[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] like Figures 1 to 6As shown, applying the technical solution of this embodiment, the anti-slip assembly of the LED display device is arranged between the box body 10 and the display module 20. The anti-slip assembly of the LED display device includes: a plug-in 30, a seat body 40 and a stopper 50. The first end of the plug-in 30 is connected to one of the box body 10 and the display module 20. The seat body 40 is arranged on the other of the box body 10 and the display module 20. The stopper 50 is movably arranged on the seat body 40, and the stopper 50 moves to have an anti-slip position for stopping the second end of the plug-in 30 and an avoidance position for avoiding the second end of the plug-in 30.

[0035] In this way, the structure of the base 40 is simple, and the stopper 50 is conveniently arranged on the base 40 in a movably manner. When the stopper 50 moves to the anti-slip position, the plug-in 30 can cooperate with the stopper 50 to stop, so that the display device and the box 10 can be fixedly connected, so that the display module 20 is more reliably fixed on the front side of the box 10, and it is convenient to install the display module 20 on the box 10. When the stopper 50 moves to the avoidance position, the stopper 50 can avoid the plug-in 30, so that the display device and the box 10 can be separated, so as to facilitate the removal of the display module 20 from the box 10. In this way, when the display module 20 is heavy, the display module 20 and the box 10 can be detachably connected by setting the stopper 50 and the plug-in 30, which improves the reliability of the connection between the display module 20 and the box 10. Furthermore, by moving the position of the stopper 50, the display module 20 can be separated from the box body 10, avoiding the need for the operator to screw the screws in the related art, making the disassembly and assembly of the display module 20 on the box body 10 simpler and more convenient. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that when the display module is heavy, the disassembly and assembly of the display module on the box body is troublesome.

[0036] like Figures 1 to 6 As shown, there are two base bodies 40 and two stoppers 50, and the two stoppers 50 are arranged on the two base bodies 40 in a one-to-one correspondence. The two base bodies 40 are arranged at intervals, and the two stoppers 50 are arranged oppositely and the moving directions of the two stoppers 50 are opposite. The two stoppers 50 are close to each other to clamp the second end of the plug-in 30 between the two stoppers 50 and cooperate with the second end stopper of the plug-in 30, so that the stopper 50 is in the anti-slip position. The two stoppers 50 are away from each other to avoid the second end of the plug-in 30, so that the stopper 50 is in the avoidance position. The above arrangement makes it more reliable for the second end of the plug-in 30 to stop and cooperate with the stopper 50 when the stopper 50 is in the anti-slip position, so that the connection between the display module 20 and the box body 10 is more reliable. And when the stopper 50 is in the avoidance position, the two stoppers 50 are away from each other so that the plug-in 30 can be separated from the stopper 50, which improves the efficiency of disassembling the display module 20 from the box body 10.

[0037] In this embodiment, the plug-in 30 is connected to the rear side of the display module 20, and the base 40 is disposed on the box 10. The plug-in 30 is a metal piece.

[0038] In other embodiments, the seat 40 and the stopper 50 are both one, and the box 10 includes a box body and a convex rib or a vertical plate arranged on the box body. When the stopper 50 is in the anti-slip position, the second end of the plug-in 30 is located between the stopper 50 and the convex rib or the vertical plate, so as to connect the display module 20 to the box 10 and prevent the display module 20 from slipping off. When the stopper 50 is in the avoidance position, the second end of the plug-in 30 can be detached from between the stopper 50 and the convex rib or the vertical plate, so that the display module 20 can be removed from the box 10. The plug-in 30 is connected to the box 10, and the seat 40 is arranged at the rear side of the display module 20.

[0039] like Figures 1 to 6 As shown, the LED display device anti-drop assembly further includes an elastic member 60 disposed between the seat body 40 and the stopper 50, and the elastic member 60 applies elastic force to the stopper 50 to keep the stopper 50 in the anti-drop position. The setting of the elastic member 60 facilitates the stopper 50 to be kept in the anti-drop position, so that the stopper 50 can keep the stopper 50 in the anti-drop position, so that the stopper 50 can keep the stopper cooperation with the second end of the plug-in 30, so that the setting of the display module 20 on the box body 10 is more reliable. In this embodiment, the elastic member 60 is a spring.

[0040] like Figures 1 to 8 As shown, the base 40 includes a connecting plate 41 connected to the other of the box 10 and the display module 20 and a mounting plate 42 disposed on the connecting plate 41, and the stopper 50 includes a slide bar 51 passing through the mounting plate 42 and a stopper block 52 disposed at the first end of the slide bar 51. The arrangement of the mounting plate 42 and the slide bar 51 facilitates the movement of the stopper 50 on the base 40, and the structures of the mounting plate 42 and the stopper block 52 are simple and easy to process. In addition, the arrangement of the stopper block 52 facilitates the cooperation with the stopper at the second end of the plug-in 30.

[0041] like Figures 1 to 8 As shown, a stop hole 43 is provided on the mounting plate 42, and the slide bar 51 is inserted into the stop hole 43 and cooperates with the stop hole 43 to stop rotation. The setting of the stop hole 43 can limit the rotation of the slide bar 51, so that the movement of the slide bar 51 on the mounting plate 42 is more stable, and then the movement of the stop block 52 is more stable, so that the switching of the stop member 50 between the anti-slip position and the avoidance position is more stable and reliable. The stop member 50 also includes a limit block 53 provided at the second end of the slide bar 51, and the limit block 53 is limitedly cooperated with a side of the mounting plate 42 away from the stop block 52. The setting of the limit block 53 makes the movement of the slide bar 51 on the mounting plate 42 more reliable, and the limit cooperation between the limit block 53 and the mounting plate 42 reduces the possibility of the slide bar 51 coming off the mounting plate 42.

[0042] In this embodiment, two mounting plates 42 are spaced apart along the axis direction of the slide bar 51, and the stop block 53 is limitedly matched with the mounting plate 42 near the second end of the slide bar 51. The elastic member 60 is disposed between the mounting plate 42 near the stop block 52 and the stop block 52. The anti-rotation hole 43 is a square hole, and the cross section of the slide bar 51 along the direction perpendicular to its axis is a square.

[0043] In other embodiments, the mounting plate 42 is provided with a stop hole 43, and the slide bar 51 is inserted into the stop hole 43 and is engaged with the stop hole 43. Alternatively, the stopper 50 further includes a limit block 53 disposed at the second end of the slide bar 51, and the limit block 53 is engaged with a side of the mounting plate 42 away from the stop block 52.

[0044] like Figures 1 to 8 As shown, the plug-in 30 includes an insertion rod 31 connected to one of the housing 10 and the display module 20 and a plug 32 arranged at one end of the insertion rod 31. The structure of the insertion rod 31 and the plug 32 is simple, which is convenient for processing the plug-in 30. The end of the plug 32 away from the insertion rod 31 has a first curved surface 33, and the first curved surface 33 gradually tilts outward along the direction away from the insertion rod 31 to the direction close to the insertion rod 31. In this way, when the plug-in 30 is inserted between the two stoppers 50, the first curved surface 33 can abut against the stopper 50, so that the stopper 50 switches from the avoidance position to the anti-slip position, making the position switching of the stopper 50 more convenient. The end of the plug 32 facing the insertion rod 31 has a second curved surface 34, and the second curved surface 34 gradually tilts inward along the direction away from the insertion rod 31 to the direction close to the insertion rod 31. In this way, when the plug-in 30 is separated from between the two stoppers 50, the second curved surface 34 can abut against the stopper 50, so that the stopper 50 switches from the anti-slip position to the avoidance position, making the position switching of the stopper 50 more convenient. In addition, the operator can drive the movement of the plug-in 30 through the plug-in 30 on the front side of the display module 20, so that the stopper 50 switches between the anti-slip position and the avoidance position, and one operator can operate the disassembly and installation of the display module 20 on the box 10. Compared with the related art that requires at least two operators to disassemble and install the display module 20, the application of the technical solution of this embodiment improves the disassembly and assembly efficiency of the display module 20 on the box 10, reduces the labor intensity of the operator, and also reduces the labor cost.

[0045] In other embodiments, the plug 30 includes a plug rod 31 connected to one of the box 10 and the display module 20 and a plug 32 disposed at one end of the plug rod 31; the end of the plug 32 away from the plug rod 31 has a first curved surface 33, and the first curved surface 33 gradually tilts outwards in a direction away from the plug rod 31 to approach the plug rod 31. Alternatively, the end of the plug 32 facing the plug rod 31 has a second curved surface 34, and the second curved surface 34 gradually tilts inwards in a direction away from the plug rod 31 to approach the plug rod 31.

[0046] like Figures 1 to 8 As shown, the plug-in 30 includes an insertion rod 31 connected to one of the housing 10 and the display module 20 and a plug 32 arranged at one end of the insertion rod 31. The structure of the insertion rod 31 and the plug 32 is simple, which is convenient for processing the plug-in 30. The end of the plug 32 away from the insertion rod 31 has a first curved surface 33, and the first curved surface 33 gradually tilts outward along the direction away from the insertion rod 31 to the direction close to the insertion rod 31. In this way, when the plug-in 30 is inserted between the two stoppers 50, the first curved surface 33 can abut against the stopper 50, so that the stopper 50 switches from the avoidance position to the anti-slip position, making the position switching of the stopper 50 more convenient. The end of the plug 32 facing the insertion rod 31 has a second curved surface 34, and the second curved surface 34 gradually tilts inward along the direction away from the insertion rod 31 to the direction close to the insertion rod 31. In this way, when the plug-in 30 is separated from the two stoppers 50, the second curved surface 34 can abut against the stopper 50, so that the stopper 50 is switched from the anti-slip position to the avoidance position, making the position switching of the stopper 50 more convenient. The curvature of the second curved surface 34 is greater than the curvature of the first curved surface 33, so that it is easier for the plug-in 30 to drive the stopper 50 to switch from the avoidance position to the anti-slip position, and it is more difficult for the plug-in 30 to drive the stopper 50 to switch from the anti-slip position to the avoidance position. In this way, it is easier for the plug-in 30 to enter between the two stoppers 50, and the efficiency of the connection between the display module 20 and the box 10 is improved. It is more difficult for the plug-in 30 to be pulled out from between the two stoppers 50, so that the stopper cooperation between the plug-in 30 and the stopper 50 is more reliable, further reducing the possibility of the display module 20 falling off from the box 10 under the action of its own gravity, and improving the reliability of the connection between the display module 20 and the box 10.

[0047] It should be noted that curvature refers to the degree of curvature of a surface. The greater the curvature, the greater the curvature of the surface.

[0048] like Figures 1 to 8 As shown, a guide curved surface 521 is provided on one end of the stop block 52 away from the slide bar 51. The provision of the guide curved surface 521 facilitates the guiding cooperation between the stop block 52 and the plug-in 30, so that the switch of the stop member 50 between the avoidance position and the anti-slip position is smoother. A positioning groove 11 is provided on the other of the box body 10 and the display module 20, and the connecting plate 41 is installed in the positioning groove 11. The provision of the positioning groove 11 facilitates the installation of the connecting plate 41 on the other of the box body 10 and the display module 20. And installing the connecting plate 41 in the positioning groove 11 can play a role in pre-positioning the connecting plate 41, and reduce the movement of the connecting plate 41 after installation, so that the installation of the connecting plate 41 on the other of the box body 10 and the display module 20 is more stable and reliable.

[0049] In other embodiments, a guide curved surface 521 is provided on one end of the stop block 52 away from the slide bar 51. Alternatively, a positioning groove 11 is provided on the other of the box body 10 and the display module 20, and the connecting plate 41 is installed in the positioning groove 11.

[0050] like Figures 1 to 8 As shown, the anti-slip assembly of the LED display device also includes a fastener 12 connecting the seat 40 and the other one of the box 10 and the display module 20. The setting of the fastener 12 can connect the seat 40 and the other one of the display module 20, and the structure is simple and reliable. The anti-slip assembly of the LED display device also includes a positioning member arranged between the seat 40 and the other one of the box 10 and the display module 20. The positioning member includes a positioning column 13 and a positioning hole 44, the positioning column 13 is arranged on the other one of the display module 20, and the positioning hole 44 is arranged on the seat 40. The setting of the positioning member facilitates the positioning of the seat 40 and the other one of the box 10 and the display module 20, so that the positioning of the seat 40 on the other one of the box 10 and the display module 20 is more accurate. The structure of the positioning column 13 and the positioning hole 44 is simple and easy to process. In addition, the setting of the positioning member reduces the use of the fastener 12, so that the connection of the seat 40 with the other one of the box 10 and the display module 20 is more convenient and quick.

[0051] In this embodiment, the fastener 12 is a screw, and a threaded hole is provided on another one of the display modules 20 . The screw passes through the base 40 and extends into the threaded hole.

[0052] In other embodiments, the anti-detachment assembly of the LED display device further includes a fastener 12, which connects the base 40 with the other of the box 10 and the display module 20. Alternatively, the anti-detachment assembly of the LED display device further includes a positioning member, which is disposed between the base 40 and the other of the box 10 and the display module 20, and the positioning member includes a positioning column 13 and a positioning hole 44, one of the positioning column 13 and the positioning hole 44 is disposed on the other of the box 10 and the display module 20, and the other of the positioning column 13 and the positioning hole 44 is disposed on the base 40.

[0053] In other embodiments, the positioning member includes a positioning post 13 and a positioning hole 44 . The positioning hole 44 is disposed on another one of the display modules 20 , and the positioning post 13 is disposed on the base 40 .

[0054] In this embodiment, the display module 20 is fixed to the front side of the box 10 by magnetic attraction, and the anti-drop assembly can prevent the display module from falling off the box when the magnetic attraction fails. This makes the front installation and maintenance of the display module 20 on the box 10 more convenient and reliable when the display module 20 is large and heavy.

[0055] The present application also provides an LED display device, which includes a housing 10 and a display module 20 disposed on the front side of the housing 10. The LED display device also includes an anti-slip component disposed between the housing 10 and the display module 20, and the anti-slip component is the anti-slip component of the above-mentioned LED display device. Since the anti-slip component of the above-mentioned LED display device can solve the problem in the related art that when the display module is heavy, the disassembly and assembly operation of the display module on the housing is troublesome, the LED display device having the anti-slip component can solve the same technical problem.
