CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International application No. PCT/CN2018/082565 filed on Apr. 10, 2018, which claims the benefit and priority of Chinese patent application No. 201710233909.5 filed on Apr. 11, 2017. Both of these applications are incorporated herein in their entirety by reference. 
    
    
     TECHNICAL FIELD 
     The present invention relates to a guiding device and a display device, and more particularly, to a guiding device and a self-unloading anti-separation display device. 
     BACKGROUND 
     The existing display screen usually includes a display screen frame and a display screen installed in the display screen frame, wherein a signal connector of the display screen is connected to a signal interface on the display screen frame. Since the connection between the signal connector of the display screen and the signal interface on the display screen frame has certain tightness, and both the frame and the display screen are provided with a magnet, and the two are adsorbed by the magnets, so that the display screen and the frame are tightly installed. Therefore, when a display module needs to be unloaded from a display screen box, the display screen needs to be adsorbed by a magnetic auxiliary screen disassembly tool, so as to disassemble the display screen by offsetting the magnet adsorption force between the display screen and the frame. However, this situation is prone to have the problem that the lamp beads of the display screen are damaged by the magnetic auxiliary screen disassembling tool; moreover, on one hand, the magnetic auxiliary screen disassembling tool has a heavier weight, after the screen is disassembled, the magnetic auxiliary screen disassembling tool is possible to fall off, and on the other hand, after the display screen is disassembled from the frame, the display screen cannot be left on the frame and needs to be immediately supported. When an operator needs to perform an operation check on a plurality of screens, each screen needs to be disassembled from the frame firstly, and the display screen cannot be left on the frame if the display screen is separated from the frame. If the display screen is mistakenly disassembled, the display screen also needs to be disassembled and then is installed again. Therefore, it is easy to increase the operator&#39;s work intensity.

     The present invention further relates to a self-unloading anti-separation display device comprising the guiding device according to any one of the guiding devices above, wherein the self-unloading anti-separation display device comprises a display screen and a frame, the frame is a first component, the display screen is a second component, the frame and the display screen are cooperatively installed, a cooperative installation surface of the first component is provided with an unloading device of a guiding device, the frame is provided with a guidepost, and the display screen is provided with a guide hole. 
     The present invention has the beneficial effects that: by arranging the guiding device on the cooperative installation surface of the first component and starting the driving device of the unloading device by a control device, the driving device drives the linkage between the first transmission piece and the pushing mechanism, the pushing mechanism drives the first dowel bar on the second transmission piece to move, the first dowel bar drives the second dowel bar to move, and the second dowel bar abuts with the second component or abuts with the abutting end on the second component, so that the first component is displaced relative to the second component, thus forming a gap between the first component and the second component. When the operator separates the first component from the second component, since at least one guidepost is arranged in the cooperative installation surface of the first component, and at least one guide hole is arranged at the position of the cooperative installation surface of the second component corresponding to the guidepost, the guidepost is inserted into the guide hole, and when the pushing mechanism applies a reaction force to the second component, the guidepost moves along the guide hole. 
     Therefore, the first component cannot be completely separated from the second component while the pushing mechanism generates a gap between the first component and the second component, but the guidepost is inserted into the guide hole to support the first component or the second component. When the first component is the display screen and the second component is the frame, the guidepost is arranged in the display screen, and the guide hole is arranged in the frame; when the first component (display screen) is pulled, at the moment, the guidepost will slide along the guide hole until the guidepost is completely separated from the second component, then the display screen is separated from the frame. 
     Similarly, when the first component is the frame and the second component is the display screen, the guidepost position is arranged in the frame, and the guide hole is arranged in the display screen; when the second component (display screen) is pulled, at the moment, the guidepost will slide along the guide hole until the guide hole is completely separated from the first component. Therefore, when the display screen needs to be replaced, and dismantled for maintenance or changing the installation position thereof, the guiding device can assist in supporting the display screen already separated by the unloading device on the frame, and generate a gap between the display screen and the frame. Therefore, when the display screen is disassembled, the operator is not necessary to disassemble the display screen from the frame completely; multiple display screens can be separated at the same time and then checked one by one, if replacement is not necessary, the display screen does not need to be disassembled from the frame completely, and can be directly pushing back to the original position. 
     Even if the screen is completely disassembled, the screen is ejected out by the pushing mechanism, the display screen is supported on the frame by a guide bar, and the display screen can be disassembled by pulling. It is not necessary to use a strong magnetic screen disassembly device in the entire process, thus reducing the damage of the strong magnetic screen disassembly device to the LED lamp beads on a display panel during adsorption, reducing the working intensity, and improving the working efficiency. 
     In addition, when placing the display screen, the display screen can be supported by the guidepost which generates a gap between the display screen and a placement plane. Therefore, when the display screen is taken again, the gap is more convenient to manually pick up the display screen, and the gap also avoids the back of the display screen from directly contacting with the ground, thus reducing the wear on the back of the display screen, and reducing blot generated on the back of the display screen. 
     The present invention has a simple overall structure, is easy to produce and manufacture, has low cost, is easy to use, has strong adaptability, and saves time and labor.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The embodiments of the present invention will be described in detail hereinafter, the examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout the drawings denote the same or similar elements or the elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but cannot be construed as limiting the present invention. 
     Referring to  FIG. 1  to  FIG. 11 , in a first embodiment of the present invention below, a first component  10  is configured as a display screen, a second component  20  is configured as a frame, this embodiment is also a main embodiment of the present invention in practical application; the frame is adsorbed with the display screen by a magnet, and the display screen and the frame become an integrated self-unloading anti-separation display device after assembly. The present invention provides a guiding device for guiding the first component  10  to move on the second component  20 , the first component  10  and the second component  20  respectively have a cooperative installation surface, and at least one of the cooperative installation surface  103  of the first component and the cooperative installation surface  202  of the second component is provided with at least one unloading device  30 ; the unloading device  30  has a driving device and a pushing mechanism  50  protruding towards the second component  20 , and the pushing mechanism  50  is butted with the second component  20  to apply a counter force to the first component  10 , so as to separate the first component  10  from the second component  20 ; the cooperative installation surface  103  of the first component is provided with at least one guidepost  60 ; at least one guide hole  70  is arranged at a position of the cooperative installation surface of the second component corresponding to the guidepost  60 ; and the guidepost  60  is inserted into the guide hole  70 , and when the pushing mechanism  50  applies a reaction force to the second component, the guidepost  60  moves along the guide hole  70 . 
     Further, the guidepost  60  is arranged at each angular position of the first component, and the guidepost  60  is vertically arranged relative to the cooperative installation surface  103  of the first component. Of course, other angles between the guidepost  60  and the cooperative installation surface  103  of the first component can also be formed, which is not limited herein. The guidepost  60  is vertically arranged relative to the cooperative installation surface  103  of the first component, so that after the display screen is separated from the frame, the display screen can be conveniently removed from the frame when the operator takes away the display screen, which is also convenient for the operator to observe the state of the display screen after separating from the frame. 
     Further, the guidepost  60  is a buffer such as an air-pressure rod, a hydraulic pressure rod, or an air spring, a fixed end of the guidepost  60  being a buffer such as an air-pressure rod, a hydraulic pressure rod, or an air spring is fixedly installed with the display screen or the frame, and since the other end of the guidepost  60  being a buffer such as an air-pressure rod, a hydraulic pressure rod, or an air spring is a movable end, the guidepost  60  can be retracted. Therefore, the end is arranged towards the guide hole  70 , after the display screen and the frame are assembled, the movable end is located in the guide hole  70 , through a pushing effect of the unloading device, when the first component  10  is separated from the second component  20  by the unloading device  30 , since the guidepost  60  has an elastic force, the guidepost  60  will give a counter elastic force to the first component  10  to pop from the second component  20  at the moment when the first component  10  is separated from the second component  20 , or the guidepost  60  will give a counter elastic force to the second component  20  to pop from the first component  10 , so as to further increase the separation force of the first component  10  or the second component  20 , so that the first component  10  or the second component  20  can be conveniently and automatically disassembled, thus reducing the occurrence of the failed disassembly. 
     Further, the guidepost  60  is entirely an elongated cylinder, which facilitates better processing and installation, and can also be convenient to increase the sliding distance of the first component  10  on the second component  20  or the sliding distance of the second component  20  on the first component  10 , thus avoiding the problem that the first component  10  or the second component  20  falls off directly. Certainly, the guidepost  60  can also be an elongated cylinder having square cross-section, or an elongated cylinder having elliptical cross-section, and certainly, the cross-section shape of the guidepost  60  is not limited to the various shapes above. 
     The pushing mechanism  50  is connected to the driving device  40  in a transmission way, the pushing mechanism  50  has at least one set of telescopic dowel bars  501 , an end part of the dowel bar  501  is an inclined surface  502 , and a small end formed by the inclined surface  502  is arranged close to the cooperative installation surface  103  of the first component; and the driving device  40  drives the dowel bar  501  to move along the cooperative installation surface  103  of the first component, when the dowel bar  501  moves towards the second component  20 , the inclined surface  502  of the dowel bar  501  abuts with and moves along the second component  20 , so as to separate the first component  10  from the second component  20 . 
     By applying the technical solution of the embodiment of the present invention, the driving device  40  and the pushing mechanism  50  are arranged on the cooperative installation surface  103  of the first component to perform linkage, so as to enable the pushing mechanism  50  to move along the first component  10 , so that the pushing mechanism  50  can press the second component  20  by the inclined surface  502 , the inclined surface  502  slides on the second component  20  to gradually separate the first component  10  from the second component  20 , so as to create a gap therebetween, and the first component  10  is separated from the magnetic adsorption of the second component  20 , so as to facilitate the disassembly of the first component  10 . 
     Further, referring to  FIG. 1  to  FIG. 3 , the driving device  40  has a first transmission piece  401 ; the pushing mechanism  50  has a second transmission piece  402 , and the first transmission piece  401  and the second transmission piece  402  form an interlaced shaft transmission; the dowel bar  501  comprises a first dowel bar  5011  and a second dowel bar  5012 , and an axis of the second transmission piece  402  is provided with the first dowel bar  5011  connected therewith; an end part of the first dowel bar  5011  is movably connected to the second dowel bar  5012 , the second dowel bar  5012  linearly moves relative to the first dowel bar  5011 , and a moving direction of the second dowel bar  5012  and an extension direction of the first dowel bar  5011  are consistent or form an included angle; and the second dowel bar  5012  is slidably arranged in the cooperative installation surface  103  of the first component, and an end part of the second dowel bar  5012  is provided with the inclined surface  502 . 
     Referring to  FIG. 4  to  FIG. 5 , and further, the driving device  40  is a motor; the first transmission piece  401  is an output shaft connected to the driving device  40  in a transmission way, and has a spiral groove on an outer surface thereof; the second transmission piece  402  is a gear meshed with the output shaft, so that the output shaft is connected to the gear in a worm and gear way; an axis of the gear is provided with the first dowel bar  5011 ; The first dowel bar  5011  is a short shaft arranged on the axis of the gear; and the second dowel bar  5012  is a bar body having a connecting hole  5013  at the end part, and the connecting hole  5013  is spirally sleeved with the short shaft. 
     Further, the driving device  40  is a cylinder; the first transmission piece  401  is a gear rack connected to the driving device  40  in a transmission way, and the surface thereof has gear teeth; the second transmission piece  402  is a gear meshed with the gear rack, so that the gear rack is connected to the gear in a gear rack way; an axis of the gear is provided with the first dowel bar  5011 ; the first dowel bar  5011  is a short shaft arranged on the axis of the gear; and the second dowel bar  5012  is a bar body having a connecting hole  5013  at the end part, and the connecting hole  5013  is spirally sleeved with the short shaft. 
     The first transmission piece  401  can be the output shaft rotatably connected to the driving device  40 , the driving device  40  can drive the output shaft to rotate, and when the driving device  40  is the motor, the first transmission piece  401  can directly be the output shaft of the motor. When the driving device  40  is the cylinder, the output shaft can be the gear rack connected to an output end of the cylinder, the gear rack is meshed with the gear, and when the cylinder is linked with the gear rack, the gear rack drives the gear to rotate, so as to drive the first dowel bar  5011  to rotate, which certainly can be other power components. 
     Further, two sets of the first dowel bars  5011  are symmetrically arranged along the axis relative to the second transmission piece  402 , thus forming a double-screw rod connection. 
     In order to facilitate the production and manufacturing, the first transmission piece  401  is connected to the second transmission piece  402  in a worm and gear way, the short shaft can be integrally formed with the gear, two short shafts are preferably arranged at two end surfaces of the gear respectively, and certainly, one short shaft is also available. When two short shafts are provided, the pushing force is more balanced on the second component  20 , and the first component  10  can be effectively separated from the second component  20 . 
     Referring to  FIG. 6 , and further, the second dowel bar  5012  comprises a shaft sleeve  5014  connected to the short shaft and a pushing rod  5015  detachably clamped with the shaft sleeve  5014 , one end of the shaft sleeve  5014  is provided with the connecting hole  5013 , the other end thereof is provided with a concave clamping groove  5016 , one end of the pushing rod  5015  is provided with a clamping head  5017  adapted to the clamping groove  5016 , the other end thereof is provided with the inclined surface  502 , and the shaft sleeve  5014  is detachably clamped with the pushing rod  5015  by the clamping groove  5016  and the clamping head  5017 . 
     Further, the clamping groove  5016  is connected to the clamping head  5017  in a joggled joint way, which enables the assembly and disassembly to be easier and faster. 
     In practical application, the separation distance between the first component  10  and the second component  20  is actually greater than or equal to the thickness of the second dowel bar  5012  vertical to the direction of the first component  10 . Therefore, a size and a thickness of the second dowel bar  5012  can be set according to different usage conditions, and the separation dimension between the first component  10  and the second component  20  is adjusted. Therefore, the second dowel bar  5012  is configured as detachable shaft sleeve  5014  and pushing rod  5015 , the shaft sleeve  5014  is disassembly clamped with the pushing rod  5015 , so as to facilitate the replacement of the pushing rod  5015  with different size to meet different pushing distances. 
     Referring to  FIG. 7  to  FIG. 8 , and in addition, the shaft sleeve  5014  is a circular member, in order to facilitate the spiral generation processing in the connection hole  5013  thereof and reduce the production cost, it is necessary to configure the shaft sleeve  5014  and the pushing rod  5015  as two separable parts, the shaft sleeve  5014  can be machined by turning and milling, and the pushing rod  5015  can be a plastic part obtained by opening the mold, which is advantageous for reducing production cost and manufacturing difficulty. 
     Further, the inclined surface  502  has at least two sub-inclined surfaces  502  with different angles, the sub-inclined surfaces  502  are connected to each other, and a slop of the sub-inclined surface  502  arranged closer to the cooperative installation surface  103  of the first component is smaller than a slope of the sub-inclined surface  502  arranged farther away from the cooperative installation surface  103  of the first component. 
     In this way, when the dowel bar  501  is pushed and the inclined surface  502  abuts with a abutting end  301 , different sliding speeds will be generated in sliding, the sub-inclined surface  502  of the abutting end  301  with a smaller slope has slower speed during the sliding process, and the sub-inclined surface  502  of the abutting end  301  with a larger slope has faster speed in the sliding process. Since a larger pushing force is required to separate the second component  20  from the first component  10  at the initial stage of starting the motor, and since the smaller the degree is, the slower the pushing speed is, and the larger the force is, the motor can separate the first component  10  from the second component  20  by larger force, so that the output force of the motor can be used efficiently. Since the second component  20  is not attracted by the magnet after separating from the first component  10 , and too strong force is not required, the degree of the sub-inclined surface  502  arranged far from the cooperative installation surface  103  of the first component is increased, and the motor can output relatively minor force to complete the screen disassembly action, so that the pushing force produced by the output force of the motor is released more uniformly and effectively. 
     Referring to  FIG. 7  to  FIG. 8 , and further, the sub-inclined surface  502  comprises a first sub-inclined surface  5021  and a second sub-inclined surface  5022 , the first sub-inclined surface  5021  is arranged close to the cooperative installation surface  103  of the first component, the second sub-inclined surface  5022  is arranged far from the cooperative installation surface  103  of the first component, the slop of the first sub-inclined surface  5021  is 30 degrees, and the slop of the second sub-inclined surface  5022  is 45 degrees. This angle is the best angle in practical application and use. 
     Further, a guiding groove  101  for positioning the second dowel bar  5012  is arranged at an installation position of the second dowel bar  5012  in the first component  10 , so that the second dowel bar  5012  is stuck inside the guiding groove  101  and moves along the guiding groove  101 . 
     In this way, the storage and installation of the second dowel bar  5012  can be facilitated, and the entire second dowel bar  5012  can be prevented from protruding too much from the cooperative installation surface  103  of the first component, thus resulting in problems of ugly appearance and incontinent use and storage. 
     Further, the guiding groove  101  is a straight groove, the second dowel bar  5012  is a straight bar, a plurality of positioning bars  102  for positioning the straight bar are spanned on an opening of the straight groove by intervals, and the positioning bar  102  is arranged vertical to the extension direction of the straight bar. 
     In practical use, the second dowel bar  5012  is positioned by the positioning bar  102 , and the positioning bar  102  is an integrally formed structure on the first component  10 , which can reduce the processing procedure and processing complexity of the guiding groove  101 , can form integrally in manufacturing of the first component  10 , and prevents the second dowel bar  5012  from falling off from the first component  10 . Therefore, considering the structural strength and depanning convenience, the installation structure of the second dowel bar  5012  is the preferred form. 
     Further, the guiding groove  101  is connected to the second dowel bar  5012  by a T-shaped ring groove structure. 
     In this way, the second dowel bar  5012  can be effectively positioned on the cooperative installation surface  103  of the first component, and the T-shaped ring groove can facilitate the clamping, disassembly and processing between the second dowel bar  5012  and the guiding groove  101 . 
     Further, the guiding groove  101  is a Y-shaped groove, which has at least two branches, and the second dowel bar  5012  is a Y-shaped bar matched with the guiding groove  101 . 
     Referring to  FIG. 9 , and further, the end of the second dowel bar  5012  provided with the inclined surface  502  is formed with a pushing head  5023  having a width larger than the width of the second dowel bar  5012 , and the pushing head  5023  can enlarges the contact area with the first component  10  or the second component  20 , so that the pushing force of the second dowel bar  5012  is more stable, the intensity is more stable and larger, and the problem about the failure of pushing caused by the relative displacement of the second dowel bar  5012  and the abutting end is reduced. The pushing head  5023  can be set into a plurality of shapes, for example, when the pushing head  5023  is a trapezoidal block, the small end of the trapezoidal block is connected to the end part of the second dowel bar  5012 , two inclined sides of the trapezoidal block are located at two sides of the moving direction of the second dowel bar  5012 , and the inclined surface is located on the trapezoidal block, when the pushing head  5023  is a rectangular block, the long side of the rectangular block is connected to the end part of the second dowel bar  5012 , and the inclined surface is located on the rectangular block, or an elliptical body, which will not be elaborated herein. 
     The driving device  40  and the pushing mechanism  50  can be arranged at any position on the back of the first component  10 , and can be arranged in multiple sets, when the first transmission piece  401  rotates, the second transmission piece  402  can be driven to rotate, thereby driving the first dowel bar  5011  to rotate, and when the first dowel bar  5011  rotates, the second dowel bar  5012  is driven to moves linearly. When the shape of the first component  10  is not limited to a rectangular screen, the second dowel bar  5012  is branched into a plurality of branch rods to facilitate the use of the first component  10  with irregular edges separated from the second component  20 , when the first component  10  is in other shapes, such as a circle or a triangle, etc., the guiding groove  101  is provided with other branch grooves, and the second dowel bar  5012  is provided with other branch rods so as to abut with other points on the  20 , which facilitates the first component  10  to be separated from the second component  20 . 
     Further, the cooperative installation surface of the second component is provided with at least one abutting end. In different situations, a plurality of the unloading devices  30  can be arranged, the quantities of the abutting end  301  and the unloading device  30  are the same, or the quantity of the abutting end  301  is at least twice the quantity of the unloading device  30 . Specifically, a second dowel bar  5012  provided with an inclined surface is corresponding to an abutting end  301 . 
     Further, the abutting end  301  of the second component  20  is arranged in a raised manner, so as to facilitate the application of force to the second component  20  by the inclined surface  502  of the second dowel bar  5012 . 
     Referring to  FIG. 10  and  FIG. 11 , and further, the abutting end  301  is a protruding boss  201 , the boss  201  is a rectangle entirely, and the boss  201  is arranged to extend towards the cooperative installation surface  103  of the first component. In this way, it is more convenient for the inclined surface  502  to be butted with the second component  20 . Certainly, the shape of the boss  201  is not limited to a rectangle, but can also be a semicircle or other shapes. 
     Further, the contact surface between the abutting end  301  and the inclined surface  502  is also arranged inclinedly. In order to successfully generate the relative sliding when the inclined surface  502  is contacted with the abutting end  301  and enable the second dowel bar  5012  to slide more smoothly, an inclined shape is also available, and the contact surface between the abutting end and the inclined surface can also be a transitional arc surface with a certain slope. 
     In the second embodiment of the present invention, the present invention further relates to a self-unloading anti-separation display device, and the unloading display device comprises a display screen and a frame. Different from the first embodiment, in the present embodiment, the first component  10  is the frame, the second component  20  is the display screen, the frame and the display screen are cooperatively installed, the cooperative installation surface  103  of the first component is provided with the unloading device of the guiding device, the frame is provided with the guidepost, the display screen is provided with the guide hole, and when the display screen needs to be separated from the frame, the display screen can gradually slide away from the frame through the support of the guiding device, that is, the reverse installation of the embodiment. 
     In conclusion, the guiding device and the self-unloading anti-separation display device provided by the present invention are simple in structure and convenient in use, can effectively improve the disassembly and assembly efficiency and reduce the damage to the LED lamp beads during the disassembly and assembly process of the display device.
