CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation application of International Application No. PCT/CN2020/102994, filed on Jul. 20, 2020, which claims priority to Chinese Patent Application No. 202010614434.6, filed on Jun. 30, 2020. The disclosures of the above-mentioned applications are incorporated herein by reference in their entireties. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to the technical field of medical equipment, in particular to a hermetic tarpaulin device and a nursing room. 
     BACKGROUND 
     When patients with infectious diseases are treated, such patients need to be isolated to prevent the spread of the infectious virus to the outside world. Nowadays, patients with infectious diseases are generally transferred to wards formed by engineering construction methods such as hospitals. However, this kind of ward cannot be moved, and it takes a certain amount of time to transfer patients to the ward, which may delay the best time for treatment. Meanwhile, the cost of this kind of ward is high. In addition, when clustered infectious diseases occur, it is difficult for the ward to meet the use demand. 
     In the related art, there are some devices that can be temporarily constructed to form an isolation space to replace the above-mentioned wards. These devices generally consist of frames and canvas. When building, the frame is first unfolded into a structure that occupies a certain space, and then multiple pieces of canvas are connected to the unfolded frame, and the canvas and the frame together form a simple temporary ward. This kind of temporary ward has great defects in use. A lot of gaps exist between the connecting parts, especially when there is a severe infectious disease transmitted by aerosol, it is very easy for the infectious virus to spread to the outside world, so the isolation effect of the ward formed by the engineering construction method cannot be achieved.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present disclosure are shown in the accompanying drawings. However, the present disclosure can be implemented in many other different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the contents of the present disclosure more thorough and comprehensive. 
     It should be noted that when an element is referred to as being “fixed on” another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being “connected to” another element, it can be directly connected to the other element or intervening elements may also be present. The terms “vertical”, “horizontal”, “left”, “right”, and similar expressions are used herein for purposes of illustration only. 
     Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     The embodiments of the present disclosure provide a nursing room. The nursing room can be completely isolated from the outside world, which is suitable for nursing use of severe infectious diseases transmitted through aerosols, influenza-like infectious diseases, tuberculosis infectious diseases, unexplained infectious diseases, and frail and sick people. 
     In some embodiments of the present disclosure, as shown in  FIG.  1    to  FIG.  4   , the nursing room includes a movable support structure  100  and a hermetic tarpaulin device  200 . The movable support structure  100  mainly plays a role of support, function integration and necessary control. Rollers  101  are provided at the bottom thereof. The hermetic tarpaulin device  200  is installed on the support structure  100  to form a nursing room together with the support structure  100 . 
     It can be understood that the specific number of support structures  100  can be determined according to actual needs. For example, in the embodiments below, the nursing room may include two support structures  100 , and the nursing room may include four support structures  100 . Besides, the nursing room can also have more composition modes, for example, it can include three support structures  100 , or more support structures  100 . 
     In some embodiments of the present disclosure, the nursing room is provided with the movable support structure  100 . Therefore, when building the nursing room, it can be realized only by controlling the movement of the support structure  100 , which is convenient to build. Compared with the ward formed by engineering construction, it can significantly reduce the cost and reduce the occupied space, and can achieve complete isolation from the outside world, thereby improving the isolation effect. 
     In an embodiment, as shown in  FIG.  1    to  FIG.  4   , the nursing room includes a first support structure  110 , a second support structure  120  and a hermetic tarpaulin device  200 , and the hermetic tarpaulin device  200  is installed on the first support structure  110  and the second support structure  120 . 
     In this embodiment, the first support structure  110  and the second support structure  120  can approach or move away from each other, so as to release enough space between them to provide conditions for the hermetic tarpaulin device  200  to unfold. 
     It should be noted that the movement of the first support structure  110  and the second support structure  120  can be done manually, or by automatic control. When the latter is used, related control devices can be integrated and installed on the first support structure  110  and/or the second support structure  120 . 
     In this embodiment, the hermetic tarpaulin device  200  includes a frame  210  and a tarpaulin body  220 . The frame  210  can be unfolded or folded into a predetermined shape. The tarpaulin body  220  can be connected to the frame  210 . When the frame  210  is unfolded, the tarpaulin body  220  can be unfolded to form a hermetic space completely isolated from an outside world, and when the frame  210  is folded, the tarpaulin body  220  can be folded into a whole. 
     It should be noted herein that the tarpaulin body  220  follows the frame  210  and performs related actions, and the corresponding actions of the frame  210  can be realized manually, for example, directly apply force to the frame  210  manually, or indirectly apply force to the frame  210  manually. For example, the frame  210  can be installed on the support structure  100  (the embodiments herein are mainly presented in this way), and the support structure  100  can be manually pushed to move, so as to realize the corresponding action of the frame  210 . The corresponding action of the frame  210  can also be realized through automatic control, which can directly control the action of the frame  210  or indirectly control the action of the frame  210  through the support structure  100 . 
     In some embodiments, the frame  210  includes a plurality of support rods. The support rods are installed on the first support structure  110  and the second support structure  120 . By driving the first support structure  110  and the second support structure  120  to move, indirectly causing the support rods to perform corresponding actions, the arrangement of the frame  210  can be varied, which is not limited herein. 
     For ease of understanding, in some embodiments, as shown in  FIG.  2   , the frame  210  includes a first support upright  211 , a second support upright  212 , a first support cross rod  213  and a second support cross rod  214 , the first support upright  211  and the second support upright  212  are vertical and parallel to each other, the first support cross rod  213  and the second support cross rod  214  are horizontal and parallel to each other, the first support cross rod  213  is connected to the first support upright  211 , and the second support cross rod  214  is connected to the second support upright  212 . 
     Thus, the arrangement and combination of the first support upright  211 , the first support cross rod  213 , the second support upright  212  and the second support cross rod  214  can play the role of propping up the tarpaulin body  220 , and the structure is simple, and since the hermetic tarpaulin device  200  can form a hermetic space completely isolated from the outside world, the effect of isolation can also be improved. 
     Further, in some embodiments, a first diagonal rod  215  is provided between the first support upright  211  and the first support cross rod  213 , and/or a second diagonal rod  216  is provided between the second support upright  212  and the second support cross rod  214 . 
     Thus, the first diagonal rod  215  and/or the second diagonal rod  216  can enhance the structural strength, making the entire frame  210  more stable and reliable. 
     Further, in some embodiments, a third support cross rod  217  is provided between the first support cross rod  213  and the second support cross rod  214 . The third support cross rod  217  plays the role of connection and reinforcement, making the whole frame  210  more stable in structure. 
     As shown in  FIG.  3   , the first support upright  211  and the second support upright  212  may be installed on the first support structure  110  and the second support structure  120  respectively. This installation can be carried out after the first support structure  110  and the second support structure  120  are moved into place, and then the tarpaulin body  220  is connected to the frame  210  to form a nursing room. 
     When the first support upright  211  and the second support upright  212  are installed on the first support structure  110  and the second support structure  120  respectively, a better way is to enable the first support upright  211  and the second support upright  212  to unfold or fold correspondingly following the movement of the first support structure  110  and the second support structure  120 . Thus, the first support upright  211  and the second support upright  212  can be installed when the first support structure  110  is close to the second support structure  120 . 
     In some embodiments, the first support upright  211 , the second support upright  212 , the first support cross rod  213 , the second support cross rod  214  and the third support cross rod  217  are telescopic rods or folding rods. 
     The above process can be understood with reference to  FIG.  1    and  FIG.  2   . First, as shown in  FIG.  1   , the first support structure  110  is close to the second support structure  120 , the first support upright  211 , the second support upright  212 , the first support cross rod  213 , the second support cross rod  214  and the third support cross rod  217  are shrunk into the first support structure  110  and the second support structure  120 . Then, as shown in  FIG.  2   , under the action of external force, the first support structure  110  and the second support structure  120  are far away from each other, correspondingly, the first support upright  211  and the second support upright  212  are extended to a certain length, and the first support cross rod  213 , the second support cross rod  214  and the third support cross rod  217  are also extended to a certain length, in this way, the frame  210  is unfolded or folded following the first support structure  110  and the second support structure  120 . 
     In some embodiments, as shown in  FIG.  4   , the tarpaulin body  220  can be unfolded to form a hexahedron structure with six surfaces, an interior of the hexahedron structure forms a hermetic space, and at least one surface is designed to have an open state that communicates with the outside world and a closed state that is isolated from the outside world. 
     It should be noted herein that only the hexahedral structure is used as an example to illustrate the tarpaulin body  220 , in other embodiments, the tarpaulin body  220  may form a pentahedral structure or other polyhedral structures. 
     For the tarpaulin body  220 , at least one surface thereof includes at least one curtain, and the curtain can be moved to open or close the hermetical space. 
     It can be understood that the curtain can be separated from other parts of the tarpaulin body  220  (the base  221 ), and when the two are separated, the hermetical space can be opened. 
     In some embodiments, the tarpaulin body  220  includes a first curtain  222  and a second curtain  223 . The first curtain  222  and the second curtain  223  are connected to the base  221 . The first curtain  222  and the second curtain  223  can move away from and approach each other to open or close the hermetic space. The hermetic tarpaulin device  200  also includes a driving mechanism  230 . The driving mechanism  230  is installed on the frame  210 , for example, can be installed on the aforementioned third support cross rod  217 , and it can also replace the third support cross rod  217 . The driving mechanism  230  is for driving the first curtain  222  and the second curtain  223  to move. 
     Therefore, by driving the first curtain  222  and the second curtain  223  to move through the driving mechanism  230 , the hermetic space can be quickly opened or closed without human intervention, saving time and effort. 
     In some embodiments, as shown in  FIG.  5    to  FIG.  9   , the driving mechanism  230  includes a first driving frame  231  and a second driving frame  232  hinged to the frame  210 , the first driving frame  231  is hinged to the second driving frame  232 , a first curtain slider  233  and a first slider driving assembly  234  are provided on the first driving frame  231 , a second curtain slider  235  and a second slider driving assembly  236  are provided on the second driving frame  232 , the first slider driving assembly  234  is configured to drive the first curtain slider  233  to move along the first driving frame  231 , the first curtain slider  233  is fixedly connected to the first curtain  222 , the second slider driving assembly  236  is configured to drive the second curtain slider  235  to move along the second driving frame  232 , and the second curtain slider  235  is fixedly connected to the second curtain  223 . 
     In this embodiment, the first curtain slider  233  and the second curtain slider  235  respectively drive the first curtain  222  and the second curtain  223  to move. When the first curtain slider  233  and the second curtain slider  235  move away from each other, the first curtain  222  and the second curtain  223  open the hermetic space. When the first curtain slider  233  and the second curtain slider  235  approach each other, the first curtain  222  and the second curtain  223  enclose the hermetic space. 
     In some embodiments, the first slider driving assembly  234  includes a first driving motor  2341  and a first conveyor belt assembly  2342 , the first curtain slider  233  is fixedly connected to the first conveyor belt assembly  2342 , the second slider driving assembly  236  includes a second driving motor  2361  and a second conveyor belt assembly  2362 , and the second curtain slider  235  is fixedly connected to the second conveyor belt assembly  2362 . 
     Thus, the first curtain slider  233  and the second curtain slider  235  can be moved by driving the motor to rotate the conveyor belt assembly, thereby realizing the movement of the first curtain  222  and the second curtain  223 . 
     Further, in order to facilitate installation, in some embodiments, the driving mechanism  230  may also include a first fixing member  237  and a second fixing member  238 . The first fixing member  237  and the second fixing member  238  are fixedly installed on the frame  210  (for example, installed on the first support upright  211  and the second support upright  212  respectively), and the first fixing member  237  is opposite to the second fixing member  238 . The first driving frame  231  is hinged to the first fixing member  237 , and the second driving frame  232  is hinged to the second fixing member  238 . 
     The driving mechanism  230  may include a first fixing member  237 , a first driving frame  231 , a second driving frame  232 , a second fixing member  238 , or the like. The first fixing member  237  and the second fixing member  238  are fixedly arranged. Between the first driving frame  231  and the first fixing member  237 , between the first driving frame  231  and the second driving frame  232 , and between the second driving frame  232  and the second fixing member  238  are hinged relationships. Therefore, the driving mechanism  230  has a folding effect, so that it can be folded into the first support structure  110  and the second support structure  120  along with the frame  210 . 
     In some embodiments, a damping hinge  239  is connected between the first fixing member  237  and the first driving frame  231 , between the first driving frame  231  and the second driving frame  232 , and between the second driving frame  232  and the second fixing member  238 . Thus, the above-mentioned folding effect can be better reflected. 
     The above process can be understood by referring to  FIG.  4    to  FIG.  5    and  FIG.  7    to  FIG.  8   . First, as shown in  FIG.  4    and  FIG.  5   , when the tarpaulin body  220  is unfolded into a hexahedron structure, the driving mechanism  230  is a linear structure extending from front to back as a whole, and the driving mechanism  230  can overlap with the aforementioned third support cross rod  217 , or the driving mechanism  230  can replace the aforementioned third support cross rod  217 , and the first fixing member  237  and the second fixing member  238  can be fixedly connected to the first support upright  211  and the second support upright  212  respectively. Then, as shown in  FIG.  7   , during the contraction process of the frame  210 , the first fixing member  237  and the second fixing member  238  will shrink in the horizontal direction. That is, the first fixing member  237  and the second fixing member  238  will gradually approach in the horizontal direction, and at this time the damping hinge  239  will change a certain angle, thereby driving the first driving frame  231  and the second driving frame  232  to gradually shrink downwards. Finally, as shown in  FIG.  8   , when the first fixing member  237  and the second fixing member  238  are close together, the first driving frame  231  and the second driving frame  232  will gradually fit together. When the first support upright  211  and the second support upright  212  are retracted into the first support structure body  110  and the second support structure body  120 , the first fixing member  237  and the second fixing member  238  will descend in the vertical direction, such that the driving mechanism  230  sinks into the first support structure  110  and the second support structure  120  as a whole, and the state can refer to  FIG.  1   . 
     When the above-mentioned driving mechanism  230  is used to move the curtain, the first curtain  222  and the second curtain  223  need to be designed accordingly, for example, it can be carried out in the following manner, cut along the “I” shape at the corresponding position of the base  221 . For ease of understanding, as shown in  FIG.  4   , for example, the above cutting can be performed on one surface of a regular hexahedron. After cutting, for each curtain, such as taking the first curtain  222  as an example, the upper and lower sides of the first curtain  222  will be separated from the base  221 , and the side of the first curtain  222  close to the second curtain  223  will be separated from the second curtain. Thus, one end of the first curtain  222  close to the second curtain  223  is fixedly connected to the first curtain slider  233 , one end of the second curtain  223  close to the first curtain  222  is fixedly connected to the second curtain slider  235 , controlling the first slider driving assembly  234  and the second slider driving assembly  236  can realize the moving away and approaching of the first curtain  222  and the second curtain  223 , thereby opening or closing the hermetical space. 
     It should be pointed out that, the embodiments herein need to always provide a hermetical space completely isolated from the outside world. Therefore, in order to ensure the sealing effect, a magnetic attractor  224  is provided between the first curtain  222  and the second curtain  223 , between the first curtain  222  and other surfaces, and between the second curtain  223  and other surfaces. The magnetic attractor  224  can provide suction force, such that when the first curtain  222  and the second curtain  223  approach, the first curtain  222 , the second curtain  223  and the base  221  can be closely connected, to eliminate gaps between the first curtain  222 , the second curtain  223  and the base  221 , and between the first curtain  222  and the second curtain  223 . 
     In some embodiments, the magnetic attractor  224  can be selected according to the material of the tarpaulin body  220 . For example, when the tarpaulin body  220  is made of flexible materials such as PE/PVC/TPU, the magnetic attractor  224  can be soft magnets. For another example, when the tarpaulin body  220  is made of a relatively hard material, the magnetic attractor  224  can also be a permanent magnet or the like. 
     On the other hand, it can be seen from the foregoing description that the frame  210  can be installed on the first support structure  110  and the second support structure  120 , the tarpaulin body  220  needs to be connected to the frame  210 , so that the tarpaulin body  220  can also be unfolded when the frame  210  is unfolded. 
     For this, in an embodiment, please refer to  FIG.  4   , a cloth cover  225  is provided on the tarpaulin body  220 . The cloth cover  225  can just cooperate with the first support upright  211  and the second support upright  212 , so that the tarpaulin body  220  can be installed on the frame  210 . As shown in  FIG.  1    to  FIG.  3   , when the frame  210  shrinks into the first support structure  110  and the second support structure  120 , and the first support structure  110  and the second support structure  120  have not been separated, the tarpaulin body  220  can be hung on the frame  210 , and then the tarpaulin body  220  can form a hermetic space with the movement of the first support structure  110  and the second support structure  120  and the gradual expansion of the frame  210 . 
     It can be understood that when the tarpaulin body  220  is fully unfolded, taking the hexahedron structure as an example, the interior does not necessarily form a regular shape. For example, as mentioned above, the support structure  100  also has the function of functional integration. Therefore, in some applications, an air intake system and an exhaust system may be provided on the support structure  100  to create a negative pressure environment in the hermetic space. Then, under the influence of the negative pressure, the bottom of the tarpaulin body  220  may be sunken. 
     For this, in an embodiment, as shown in  FIG.  4   , an adhesive structure  226  is provided between the tarpaulin body  220  and the first support structure  110  and between the tarpaulin body  220  and the second support structure  120 . The adhesive structure  226  can be provided on the bottom of the tarpaulin body  220 . Specifically, the adhesive structure  226  can use Velcro to connect the bottom of the tarpaulin body  220  with the corresponding support structure  100  to prevent the aforementioned indentation. 
     In another embodiment, the driving mechanism  230  includes an electric zipper (not shown) provided between the curtain and other surfaces. The electric zipper, for example, can be installed on the third support cross bar  217 . The separation of the first curtain  222 , the second curtain  223  and the base  221  is realized through the automatic opening and closing of the electric zipper. 
     In this embodiment, it should be understood that the magnetic attractor  224  in the foregoing embodiments can also be applied to ensure the sealing effect. For example, the magnetic attractor  224  may be provided between the first curtain  222  and the second curtain  223 , between a lower side of the first curtain  222  and the base  221 , and between a lower side of the second curtain  223  and the base  221 . 
     In some other embodiments, ordinary zippers can also be provided between the first curtain  222  and the base  221 , and between the second curtain  223  and the base  221 , and the driving mechanism  230  can be designed as follows. 
     In an embodiment, as shown in  FIG.  10    and  FIG.  11   , the driving mechanism  230  includes a first driving frame  231  and a second driving frame  232  hinged to the frame  210 , the first driving frame  231  is hinged to the second driving frame  232 , a first curtain slider  233 , a first slider driving assembly  234 , a first zipper closure  233   a  and a first zipper driving assembly  234   a  are provided on the first driving frame  231 , a second curtain slider  235 , a second slider driving assembly  236 , a second zipper closure  235   a  and a second zipper driving assembly  236   a  are provided on the second driving frame  232 , the first slider driving assembly  234  is configured to drive the first curtain slider  233  to move along the first driving frame  231 , the first zipper driving assembly  234   a  is configured to drive the first zipper closure  233   a  to move along the first driving frame  231 , the first curtain slider  233  is fixedly connected to the first curtain  222 , the first zipper closure  233   a  is fixedly connected to a zipper pull of the first zipper, the second slider driving assembly  236  is configured to drive the second curtain slider  235  to move along the second driving frame  232 , the second zipper driving assembly  236   a  is configured to drive the second zipper closure  235   a  to move along the second driving frame  232 , the second curtain slider  235  is fixedly connected to the second curtain  223 , and the second zipper closure  235   a  is fixedly connected to a zipper head of the second zipper. 
     It should be noted herein that the first zipper is provided between the upper side of the first curtain  222  and the base  221 , the second zipper is provided between the upper side of the second curtain  223  and the base  221 . There are two parallel and independent slide rails in the first drive frame  231 . The first curtain slider  233  and the first zipper closure  233   a  respectively move along a slide rail. There are also two parallel and independent slide rails in the second drive frame  232 . The second curtain slider  235  and the second zipper closure  235   a  move along one slide rail, respectively. 
     In this embodiment, the first curtain slider  233  cooperates with the first zipper closure  233   a  to drive the first curtain  222  to move, and the second curtain slider  235  cooperates with the second zipper closure  235   a  to drive the second curtain  223  to move. The movement of the first curtain  222  is taken as an example herein. When the tarpaulin body  220  is in the unfolded state shown in  FIG.  3   , the first curtain  222  and the second curtain  223  are hermetically connected to each other (mainly relying on the magnetic attractor  224  between them). When the first curtain  222  is driven to move, the first zipper driving assembly  234   a  is first activated, so that the first zipper closure  233   a  pulls the zipper pull of the first zipper, thereby separating the first curtain  222  from the base  221 . Then, the first slider driving assembly  234  is activated to move the first curtain slider  233 , thereby driving the first curtain  222  to move away from the second curtain  223 , finally opening the hermetic space. On the contrary, when it is necessary to close the hermetic space, the first slider driving assembly  234  should be activated first, so that the first curtain slider  233  drives the first curtain  222  to move towards the second curtain  222 . At this time, the function of the first curtain slider  233  is to sort out the positional relationship between the first curtain  222  and the base  221 , so that the two gradually fit together. Afterwards, the first zipper driving assembly  234   a  is activated again, so that the first zipper closure  233   a  pulls on the zipper pull of the first zipper, so that the first curtain  222  and the base  221  are sealed again. 
     In some embodiments, the first zipper driving assembly  234   a  includes a third driving motor and a third conveyor belt assembly, and the first zipper closure  233   a  is fixedly connected to the third conveyor belt assembly. The second zipper driving assembly  236   a  includes a fourth driving motor and a fourth conveyor belt assembly, and the second zipper closure  235   a  is fixedly connected to the fourth conveyor belt assembly. 
     For other structural components of the driving mechanism  230  in this embodiment, reference may be made to the foregoing embodiments, which will not be repeated herein. The driving mechanism  230  in this embodiment can be understood as a modified form of the driving mechanism  230  in the preceding embodiments. It is only necessary to add the first zipper driving assembly  234   a  and the first zipper closure  233   a  on the first driving frame  231 , and add the second zipper driving assembly  236   a  and the second zipper closure  235   a  on the second driving frame  232 . 
     In another embodiment, as shown in  FIG.  12    to  FIG.  16   , the nursing room includes a first support structure  110 , a second support structure  120 , a third support structure  130 , a fourth support structure  140  and a hermetic tarpaulin device  200 . The hermetic tarpaulin device  200  is installed on the first support structure  110 , the second support structure  120 , the third support structure  130  and the fourth support structure  140 . 
     Different from the foregoing embodiments in which the first support structure  110  and the second support structure  120  are used to form the nursing room, in this embodiment, due to the adoption of four support structures  100 , the performance of the nursing room in terms of stability will be more superior. More functions can be integrated by setting more support structures  100 , for example, the above-mentioned air inlet system and air outlet system can be installed on the corresponding support structures  100 , and even lockers and air-conditioning systems can also be installed. 
     It can be understood that the various frames  210  described above can be applied in the nursing room. For example, same as the previous embodiments, the frame  210  may include a first support upright  211  and a second support upright  212 . The first support upright  211  is installed on the first support structure  110 , and the second support upright  212  is installed on the second support structure  120 . 
     In nursing rooms employing four support structures  100 , the frame  210  can also be deformed. 
     For example, in some embodiments, as shown in  FIG.  15   , the frame  210  includes a first support upright  211 , a second support upright  212 , a third support upright  211   a  and a fourth support upright  212   a.  The first support upright  211 , the second support upright  212 , the third support upright  211   a  and the fourth support upright  212   a  are vertical and parallel to each other. A fourth support cross rod  218  is provided between the first support upright  211  and the second support upright  212 . 
     The function of the fourth support cross rod  218  is similar to the function of the third support cross rod  217 , and plays the role of reinforcing the overall structural strength of the frame  210 . 
     On the other hand, in the nursing room using four support structures  100 , telescopic connecting frames  150  can also be provided between the support structures  100  (the telescopic connecting frame  150  can also be applied in the aforementioned nursing room using two supporting structures  100 ), such that the movement of the support structure  100  becomes more regulated, and the expansion and contraction of the nursing room will also be differentiated. 
     As shown in  FIG.  14   , a first telescopic connecting frame  151  is provided between the second support upright  212  and the third support upright  211 , a second telescopic connecting frame  152  is provided between the third support upright  211   a  and the fourth support upright  212   a,  and a third telescopic connecting frame  153  is provided between the fourth support upright  212   a  and the first support upright  211 . 
     In the embodiment in which the frame  210  is unfolded independently, the telescopic connecting frame  150  may also be directly provided between the support rods. 
     Here, please refer to  FIGS.  12 - 16    in combination, first please refer to  FIG.  12   , the four support structures  100  are still in the unseparated state, at this time, the tarpaulin body  220  can be installed on the four support structures  120  (through the cloth cover  225 , which is described in detail above), then fix the fourth support structure  140  (this fixation can be realized by the rollers  101  provided at the bottom of the fourth support structure  140 , and the rollers  101  can be self-locking rollers). Then, as shown in  FIG.  13   , the second support structure  120  and the third support structure  130  are moved synchronously along the C direction. Next, as shown in  FIG.  14   , the third support structure  130  and the fourth support structure  140  are fixed, and the first support structure  110  and the second support structure  120  are moved along the D direction, the first support structure  110  is separated from the fourth support structure  140 , the second support structure  120  is separated from the third support structure  130 . Next, as shown in  FIG.  15   , the frame  210  is slowly unfolded. During this process, the tarpaulin body  220  will be unfolded along with the frame  210 , and finally the nursing room shown in  FIG.  16    is formed. 
     It should be noted that in the aforementioned nursing room using two support structures  100 , designs including but not limited to those listed below have been made. The tarpaulin body  220  can adopt a hexahedron structure or other structures. The tarpaulin body  220  can include a first curtain  222  and a second curtain  223 . In order to move the first curtain  222  and the second curtain  223 , various driving mechanisms  230  are listed. It can be understood that the above designs can all be applied in the nursing room using four support structures  100 . For example, the driving mechanism  230  can be designed integrally with the fourth support cross rod  218 , or directly replace the fourth support cross rod  218 . 
     The various technical features of the above-mentioned embodiments can be combined arbitrarily, and for the sake of concise description, all possible combinations of the various technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope of the description. 
     The above-mentioned embodiments only express several implementation modes of the present disclosure, and the description thereof is relatively specific and detailed, but should not be construed as limiting the scope of the present disclosure.
