The hook body  2  is used to hang the curtain rod. 
     In view of the above-mentioned related technology, it is found that there is following deficiency: when the operator needs to hang curtain rods with different diameters, the operator needs to dismantle the vertical rod and the hook body from the ceiling, and then install a matched hook body on the ceiling, incurring inconvenient installation for the operator. 
     SUMMARY 
     In order to facilitate the installation of curtain rods with different diameters for an operator, the present application provides a curtain rod hanging structure. 
     A curtain rod hanging structure provided in the present application adopts the following technical solution. 
     A curtain rod hanging structure includes a vertical rod and a hook body, the hook body is provided on the vertical rod, an installation groove is provided in an inner wall of the hook body, and an adjusting pad is detachably arranged in the installation groove and configured to hang the curtain rod. 
     With the above technical solution, when in use, the operator removes the adjusting pad from the installation groove, and replaces an adjusting pad which is adapted to the corresponding curtain rod. The operator only needs to replace the adjusting pad to realize the installation of curtain rods with different diameters, which facilitate the operation for the operator. 
     Optionally, the adjusting pad is elastic, and is snap connected in the installation groove. 
     With the above technical solution, when in use, the operator only needs to bend the adjusting pad and removes the adjusting pad out of the installation groove, which facilitate the replacement the adjusting pad for operator. 
     Optionally, a plurality of anti-slip grooves are provided in a sidewall of the adjusting pad close to an inner wall of the hook body. 
     With the above technical solution, the friction force between the adjusting pad and the inner wall of the hook body is increased by providing the anti-slip grooves, so as to reduce the occurrence of detaching of the adjusting element from the installation groove during use. 
     Optionally, the vertical rod includes a fixing tube and a sliding rod, in which the sliding rod is slidably connected inside the fixing tube, and the sliding rod is in friction connection with the inner wall of the fixing tube, and the hook body is arranged on the sliding rod. 
     With the above technical solution, when installing, the operator can realize the height adjustment of the curtain rod by adjusting the position of the sliding rod relative to the fixing tube, so as to further facilitate the installation for operator. 
     Optionally, the fixing tube is provided with an installation assembly, the installation assembly includes an installation plate and a fixing screw, the installation plate is provided with a plurality of installation through-holes and the fixing screw is threadedly connected on the installation plate, the fixing screw penetrates the installation plate and the fixing tube is threadedly connected with the fixing screw. 
     With the above technical solution, when installing the fixing tube in a room, the expansion bolt is passed through the installation through-hole by the operator, so as to install the installation plate in the room, and then the fixing tube is threadedly connected with the fixing screw to realize the installation of the fixing tube in the house, which facilitate the installation for operator. 
     Optionally, a rubber ring is provided on the outer sidewall of the sliding rod, and the outer wall of the rubber ring abuts against the inner wall of the fixing tube. 
     With the above technical solution, the rubber ring abutting against the inner wall of the fixing tube achieves a damping effect between the sliding rod and the fixing tube, so that the structure is simple. 
     Optionally, a connecting tube is provided on the sidewall of the fixing tube, the connecting tube is communicated with the fixing tube, a unidirectional structure is provided in the connecting tube, the unidirectional structure includes a unidirectional tapered body and an unidirectional spring for keeping the directional tapered body closing the connecting tube, the unidirectional tapered body is slidably connected in the connecting tube in the direction approaching or departing from the fixing tube, and the outer diameter of the unidirectional tapered body is gradually increased along the direction from the fixing tube to connecting tube. 
     With the above technical solution, when installing the fixing tube, the operator threadedly connects the fixing tube with the fixing screw, so that air or medium between the fixing screw and the sliding rod can drive the sliding rod to slide to the farthest position in the fixing tube. For adjusting the relative position between the sliding rod and the fixing tube, the operator presses the sliding rod into the fixing tube, so that air or medium between the fixing screw and the sliding rod drives the unidirectional tapered body to move in the direction away from the fixing tube, so as to compress the unidirectional spring. After adjusting, the unidirectional spring drives the unidirectional tapered body to move in the direction approaching the fixing tube, so that the unidirectional tapered body closes the connecting tube. This realizes the effect that the relative position between the sliding rod and the fixing tube will not change when the operator pulls the curtain to improve the overall stability during use, since the external air is blocked by the unidirectional tapered body. 
     Optionally, a closing assembly is provided between the connecting tube and the fixing tube, the closing assembly includes a tapered closing body, a return spring for keeping the tapered closing body closing the communicating portion between the connecting tube and the fixing tube, and a driving structure for driving the tapered closing body to move in the direction away from the connecting tube, and the outer diameter of the tapered closing body is gradually decreased along the direction from the fixing tube to the connecting tube. 
     During the threaded connecting of the fixing tube to the fixing screw, air between the sliding rod and the fixing screw can be discharged out of the unidirectional tapered body, so that it is difficult for the fixing tube to drive the sliding rod to move during the threaded connecting of the fixing tube to the fixing screw. 
     With the above technical solution, during the threaded connecting of the fixing tube to the fixing screw, the return spring and the tapered closing body close the communicating portion between the connecting tube and the fixing tube, so as to reduce the possibility of the air between sliding rod and the fixing screw leaking out of the connecting tube. The sliding rod drives the tapered closing body to move in the direction away from the connecting tube when sliding to the limit position in the fixing tube, so that the communicating portion between the connecting tube and the fixing tube is opened, which facilitates the fixing tube to drive the sliding rod to move during the threaded connecting of the fixing tube to the fixing screw. 
     Optionally, the driving structure includes a driving ring, the driving ring is arranged at the tail of the fixing screw, and the driving ring is configured to abut against the sidewall of the tapered closing body. 
     With the above technical solution, during the threaded connecting of the fixing tube to the fixing screw, the driving ring moves in the direction approaching the tapered closing body, so that the driving ring abuts against the sidewall of the tapered closing body, and the driving ring drives the tapered closing body to move in the direction away from the connecting tube. This realizes the movement of the tapered closing body in the direction away from the connecting tube during the threaded connecting of the fixing tube to the fixing screw, so that the structure is simple. 
     Optionally, a leveling assembly is provided in the connecting tube, the leveling tube includes a transparent box, a partition plate, a first sliding plate and a second sliding plate, the partition plate is fixedly connected inside the transparent box, the partition plate divides the transparent box into two cavities, that is, a first cavity and a second cavity, respectively, the first sliding plate is slidably connected inside the first cavity, the second sliding plate is slidably connected inside the second cavity, a first communicating pipe is communicated with the bottom of the first cavity inner wall, a second communicating pipe is communicated with the bottom of the second cavity inner wall, and the first communicating pipe is configured to communicate with the connecting tube. 
     With the above technical solution, when in use, two fixing tubes are threadedly connected to two fixing screws respectively by the operator to realize the installation of the curtain rod hanging structure in the room. Air between the fixing screw and the sliding rod drives the sliding rod to move to the limit position, so as to realize “zero adjustment” of the sliding rod. Air inside the fixing tube is discharged through unidirectional tapered body under air pressure. After the air pressure in the fixing tube is stabilized, the first communicating pipe is communicated with one of the connecting tubes, and the second communicating pipe is communicated with the other of the connecting tubes. When adjusting the extension length of one sliding rod, air between the sliding rod and the fixing screw is discharged from the fixing tube through unidirectional tapered body, and then enters the first cavity through first communicating pipe, so that the first sliding plate in the first cavity moves upward vertically. When adjusting the extension length of another sliding rod, air between the sliding rod and the fixing screw is discharged from fixing tube through unidirectional tapered body, and then enters the second cavity through second communicating pipe, so that the second sliding plate in the second cavity moves upwards vertically. The operator only needs to observe and compare the heights of the first sliding plate and the second sliding plate to control the extension length of two sliding rods, which facilitates the leveling of the curtain rod for operator. 
     In conclusion, the present application achieves at least one following beneficial effect: 
     1. it is convenient for an operator to replace the curtain rods with different diameters through installation groove and adjusting pad;

     Embodiment 2 
     Referring to  FIG.  5    and  FIG.  6   , this embodiment differs from Embodiment  1  in that. a rubber ring  14  is sleeved on the sliding rod  12 . The rubber ring  14  is fixedly connected to the sliding rod  12  and the outer sidewall of the rubber ring  14  abuts against the inner sidewall of the fixing tube  11 . A blocking ring  15  is fixedly connected to the end of the fixing tube  11  away from the fixing screw  34 . A connecting tube  4  is fixedly connected to the outer sidewall of the fixing tube  11 , the fixing tube  4  is communicated with the fixing tube  11 , and is positioned between the fixing screw  34  and sliding rod  12 . 
     Referring to  FIG.  6    and  FIG.  7   , a closing assembly  5  is provided at the communicating portion between the connecting tube  4  and fixing tube  11 .

The tapered closing body  51  is positioned on the side of the connecting tube  4  facing the fixing tube  11 . The outer diameter of the tapered closing body  51  is gradually increased along the connecting tube  4  in the direction approaching the fixing tube  11 , and the outer sidewall of the tapered closing body  51  is configured to close the communication portion between the connecting tube  4  and fixing tube  11 . The length direction of the return spring  52  is parallel to the length direction of the connecting tube  4 . One end of the return spring  52  is fixedly connected to the end of the tapered closing body  51  departing from the connecting tube  4 , and anther end of the return spring  52  is fixedly connected to the inner wall of the fixing tube  11 . 
     Referring to  FIG.  6    and  FIG.  7   . the driving structure  53  includes a driving ring  531 , the driving ring  531  is coaxial with the fixing screw  34 , and is fixedly connected to the end of the fixing screw  34  close to the blocking ring  15 , and a guiding slope is provided between the end of the driving ring  531  close to the blocking ring 15  and the inner sidewall of the driving ring  531 , which is used to abut against the outer sidewall of the tapered closing body  51 . 
     When in use, the fixing tube  11  is threadedly connected to the fixing screw  34  by the operator, so that air between the fixing screw  34  and the sliding rod  12  drives the sliding rod  12  to slide to a limit position, and the blocking ring  15  blocks the sliding rod  12 . When the operator continues to screw the fixing tube  11  to the fixing screw  34 , the driving ring  531  moves in the direction approaching the tapered closing body  51 , so that the outer sidewall of the tapered closing body  51  abuts against the guiding slope  532  of the driving ring  531 , and the guiding slope  532  drives the tapered closing body  51  to move in the direction away from the connecting tube  4 . Thereby, the communication portion between the connecting tube  4  and fixing tube  11  is opened by the tapered closing body  51 . 
     Referring to  FIG.  6   , a unidirectional structure  6  is provided at the connecting tube  4  departing from the fixing tube  11 . The unidirectional structure  6  includes a unidirectional tapered body  61 , a unidirectional tube  62  and a unidirectional spring  63  for keeping the directional tapered body  61  closing the connecting tube  4 . The end of the unidirectional tube  62  is fixedly and coaxially connected to the end of the connecting tube  4  away from the fixing tube  11 . A fixing plate  64  is fixedly connected in the unidirectional tube  62 , the unidirectional tapered body  61  is positioned between the fixing plate  64  and the connecting tube  4 , and the outer diameter of the unidirectional tapered body  61  is gradually decreased along the direction from connecting tube  4  to fixing tube  11 . The unidirectional spring  63  is positioned between the fixing plate  64  and the unidirectional tapered body  61 , one end of the unidirectional spring  63  is fixedly connected to the fixing plate  64  and the other end of the unidirectional spring  63  is fixedly connected to the unidirectional tapered body  61 , and the outer sidewall of the unidirectional tapered body  61  is configured to abut against the communication portion between the unidirectional tube  62  and the connecting tube  4 . 
     When in use, the operator screws the fixing screw  34  into the fixing tube  11 , so that the sliding rod  12  slides to the limit position, and then the driving ring  531  drives the tapered closing body  51  to open the connecting tube  4 . The operator can press the sliding rod  12  along the direction approaching the fixing screw  34 , so that the air between the fixing screw  34  and the sliding rod  12  is discharged through unidirectional tapered body  61 . Since the external air is blocked by the unidirectional tapered body  61 , the external air is hard to enter into the fixing tube  11 , which can reduce the possibility of unintended sliding of the sliding rod  12  by the operator, and improves the overall stability during use. 
     Referring to  FIG.  5    and  FIG.  6   , two curtain rod hanging structures are provided, and a leveling assembly  7  is provided between two connecting tubes  4 . The leveling assembly  7  includes a transparent box  71 , a partition plate  72 , a first sliding plate  73  and a second sliding plate  74 . The partition plate  72  is vertically arranged and fixedly connected in the transparent box  71 , the partition plate  72  divides the transparent box  71  into two cavities  8 , that is, a first cavity  81  and a second cavity  82 , respectively. The first sliding plate  73  is slidably connected inside the first cavity  81 , and the second sliding plate  74  is slidably connected inside the second cavity  82 . A first communicating pipe  75  is fixedly connected with the bottom of the first cavity  81  inner wall, the first communicating pipe  75  is communicated with the first cavity  81 , and the end of the first communicating pipe  75  away from the transparent box  71  is sleeved on one of the unidirectional tubes  62 . A second communicating pipe  76  is fixedly connected on the inner bottom wall of the second cavity  82 , the second communicating pipe  76  is communicated with the second cavity  82 , and the end of the second communicating pipe  76  away from the transparent box  71  is sleeved on the other of the unidirectional tubes  62 . The first communicating pipe  75  and the second communicating pipe  76  are both made of rubber. 
     When in use, the operator installs two curtain rod hanging structures on the ceiling, then screws the fixing screw  34  into the fixing tube  11 , so that the sliding rod  12  slides to the limit position in the fixing tube  11 , and then the driving ring  531  drives the tapered closing body  51  to open the connecting tube  4 . After standing for a period of time to balance the internal air pressure with the external air pressure, the first communicating pipe  75  is sleeved on one of the unidirectional tubes  62  and the second communicating pipe  76  is sleeved on another unidirectional tube  62 . When the operator adjusts the extension length of one sliding rod  12 , air extruded by the sliding rod  12  enters the first cavity  81  via the unidirectional tapered body  61 , the unidirectional tube  62  and the first communicating pipe  75 , so that the first sliding plate  73  in the first cavity  81  is lifted. When the operator adjusts the extension length of another sliding rod  12 , the operator only needs to observe the heights of the second sliding plate  74  and the first sliding plate  73 , so as to realize the leveling of the curtain rod, which facilitates the operation for operator. 
     The implementing principle of Embodiment 2 is as follows. When in use, the operator screws the fixing screw  34  into the fixing tube  11 , so that air between the fixing screw  34  and the sliding rod  12  drives the sliding rod  12  to slide to the limit position, thereby realizing “zero adjustment” of the sliding rod  12 . After standing for a period of time, the air pressure inside the fixing tube  11  is stabilized with the external air pressure, and the two unidirectional tubes  62  are connected with each other by the first communicating pipe  75  and the second communicating pipe  76 . When the operator adjusts one of the sliding rods  12 , the air inside the fixing tube  11  lifts the first sliding plate  31 , and when adjusting the other sliding rod  12 , the air discharged from the fixing tube  11  lifts the second sliding plate  74 . The operator can realize the leveling of the curtain rods through heights of the first sliding plate  73  and second sliding plate  74 . 
     The above are the preferred embodiments of the present application, which are not intend to limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
