Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0042] like Figures 1 to 10 As shown, the plug-in assembly of the LED display device of this embodiment includes: a first plug-in structure 10, a second plug-in structure 20 and a first locking member 30. The first plug-in structure 10 includes a first seat body 11 and a first plug-in member 12 arranged on the first seat body 11. The second plug-in structure 20 includes a second seat body 21, a second plug-in member 22 movably arranged on the second seat body 21, and a driving member 23 for driving the second plug-in member 22 to move. The first locking member 30 is movably arranged on the driving member 23, and a first matching portion is arranged on the second seat body 21. The first locking member 30 is movably arranged so that the first locking member 30 has a first locking position in which it is locked and matched with the first matching portion and a first unlocking position separated from the first matching portion. In this embodiment, the driving member 23 drives the second connector 22 to move so that the second connector 22 has a connection position plugged with the first connector 12 and a disconnection position separated from the first connector 12. When the second connector 22 is in the connection position, the first locking member 30 can move from the first unlocking position to the first locking position to keep the second connector 22 in the connection position. When the second connector 22 is in the plugged connection position with the first connector 12, the first plug structure 10 is connected with the second plug structure 20, further realizing the connection of the two boxes, and finally realizing the power connection and signal transmission of the LED display device.

[0043] By applying the technical solution of this embodiment, the first plug-in structure 10 can be installed on an adjacent box, and the second plug-in structure 20 can be installed on another adjacent box. The driving member 23 drives the second plug-in connector 22 to move so that the second plug-in connector 22 has a connection position plugged with the first plug-in connector 12 and a disconnection position separated from the first plug-in connector 12. When the second plug-in connector 22 is in the connection position, the first locking member 30 can be moved from the first unlocking position to the first locking position to keep the second plug-in connector 22 in the connection position. In this way, the second plug-in connector 22 can be kept in the connection position and is not easy to loosen, which ensures that the second plug-in connector 22 can effectively be plugged and matched with the first plug-in connector 12 to maintain a good contact effect and avoid poor contact. Therefore, the technical solution of this embodiment can solve the problem that the integrated plug in the related art is easy to loosen, which makes the integrated plug and the integrated socket easy to have poor contact. Furthermore, the first plug-in structure 10 and the second plug-in structure 20 can replace the wire connection between the boxes in the related art, and realize the function of quickly connecting the power and signals between the boxes after the overall assembly of the LED display device is completed, thereby realizing the on-off control of the connection between the boxes, facilitating the assembly or disassembly of the boxes by on-site personnel, and solving the problem of difficulty in introducing external power and signals.

[0044] It should be noted that the second plug-in component 22 can move linearly, and the first locking component 30 can move linearly.

[0045] like Figure 3 and Fig. 9 As shown, the first locking member 30 includes a first locking column 31, and the first matching portion includes a first matching hole 211 corresponding to the first locking column 31. In this way, the first locking column 31 can be inserted into the first matching hole 211, and the first locking member 30 can be moved from the first unlocking position to the first locking position. The first locking column 31 cooperates with the first matching hole 211, so that the first locking member 30 is easy to use and reliable in locking.

[0046] like Figure 3 and Fig. 9 As shown, the first locking member 30 also includes a first operating portion 32 disposed on the first locking column 31. A first mounting hole 231 is disposed on the driving member 23, and the first locking column 31 is movably disposed in the first mounting hole 231. The operating end of the first operating portion 32 is located outside the first mounting hole 231. The arrangement of the first operating portion 32 facilitates the movement of the first locking column 31 and is convenient to use. The first operating portion 32 is a first pin structure fixedly connected to the first locking column 31, and the operating end of the first operating portion 32 is a first operating head, which has a first straight protrusion.

[0047] like Figure 2 , Figure 3 and Figure 8As shown, a convex-concave contact structure is provided between the driving member 23 and the second plug connector 22. The convex-concave contact structure includes an arc-shaped convex portion 221 and a concave portion 232 wrapped around the arc-shaped convex portion 221, and the concave portion 232 rotates around the arc-shaped convex portion 221 so that the driving member 23 drives the second plug connector 22 to move. In this way, the arc-shaped convex portion 221 can support the driving member 23, and the arc-shaped convex portion 221 can form a rotation path of the concave portion 232, so that the driving member 23 can drive the second plug connector 22 to move smoothly and directly. In this way, the second plug structure 20 has a simple structure and is easy to drive.

[0048] Specifically, by pressing the upper end of the recessed portion 232, the recessed portion 232 rotates counterclockwise around the arc-shaped protrusion 221, and the driving member 23 drives the second connector 22 to move downward, so that the second connector 22 is switched from the connected position to the disconnected position. By pressing the lower end of the recessed portion 232, the recessed portion 232 rotates clockwise around the arc-shaped protrusion 221, and the driving member 23 drives the second connector 22 to move upward, so that the second connector 22 is switched from the disconnected position to the connected position.

[0049] like Figure 2 , Figure 4 and Fig. 9 As shown, the arc-shaped convex portion 221 is arranged on the second plug-in member 22, and the concave portion 232 is arranged on the driving member 23. The second plug-in member 22 includes a plug-in block 222 and two vertical blocks 224 arranged at intervals on one side of the plug-in block 222, and the arc-shaped convex portion 221 is arranged on one side of the plug-in block 222 and located between the two vertical blocks 224. The driving member 23 is rotatably connected to the corresponding vertical block 224 through a rotating shaft 233. The moving direction of the first locking member 30 is parallel to the axis of the rotating shaft 233, and the moving direction of the second plug-in member 22 is perpendicular to the axis of the rotating shaft 233. The setting of the two vertical blocks 224 can limit the movement of the driving member 23 along the axis direction of the rotating shaft 233, so as to limit the driving member 23 between the two vertical blocks 224. At the same time, the setting of the rotating shaft 233 can also limit the driving member 23 on the two vertical blocks 224, so that the concave portion 232 of the driving member 23 can only rotate around the arc-shaped convex portion 221.

[0050] like Figures 2 to 4As shown, there are two rotating shafts 233, and the driving member 23 is preferably a driving block. The two rotating shafts 233 are located on opposite sides of the driving block, and each vertical block 224 is provided with a first half hole. The second plug-in structure 20 also includes a baffle 25 connected to each vertical block 224. The baffle 25 is provided with a second half hole corresponding to the first half hole, and the first half hole and the second half hole together form a circular hole, and a rotating shaft 233 penetrates into the circular hole. The setting of the baffle 25 can limit the rotating shaft 233 in the circular hole, preventing the rotating shaft 233 from falling from the corresponding vertical block 224, and then during the movement of the second plug-in member 22, the driving member 23 can move with the second plug-in member 22, so that the driving member 23 drives the second plug-in member 22 to move more conveniently.

[0051] like Figures 4 to 8 As shown, the second plug-in structure 20 also includes an elastic member 24 disposed between the second seat body 21 and the second plug-in component 22. In the process of the driving member 23 driving the second plug-in component 22 to move so that the second plug-in component 22 switches from the disconnected position to the connected position, the elastic member 24 plays a damping role so that the second plug-in component 22 and the first plug-in component 12 can be smoothly plugged in, and the internal structure (such as the plug pin) of the second plug-in component 22 or the first plug-in component 12 is prevented from being damaged by the plug-in too quickly. In the process of the driving member 23 driving the second plug-in component 22 to move so that the second plug-in component 22 switches from the connected position to the disconnected position, the elastic member 24 provides a thrust so that the second plug-in component 22 and the first plug-in component 12 can be quickly separated, which is conducive to improving the plug-in efficiency of the first plug-in structure 10 and the second plug-in structure 20.

[0052] like Figures 4 to 12 As shown, the second seat body 21 includes a first half seat 212 and a second half seat 213 that are spaced apart. In this way, the first half seat 212 and the second half seat 213 can be fixed on a box. The second plug-in component 22 is located between the first half seat 212 and the second half seat 213. In this way, the structure of the second plug-in structure 20 is more compact and small, and occupies less space in the box. At the same time, the first half seat 212 and the second half seat 213 can simultaneously limit the two sides of the second plug-in component 22 and the two sides of the driving component 23, so as to prevent the driving component 23 from being deflected during the driving process and prevent the second plug-in component 22 from being deflected during the movement process.

[0053] like Figures 4 to 12As shown, the second plug-in connector 22 includes a plug-in block 222 and a connecting plate 223 disposed on the outer side wall of the plug-in block 222. The elastic member 24 is disposed between the connecting plate 223 and the first half seat 212 and between the connecting plate 223 and the second half seat 213. The driving member 23 drives the plug-in block 222 to move, and the first matching portion is disposed on the second half seat 213. The elastic member 24 can generate a damping effect or thrust on the movement of the connecting plate 223. At the same time, the first half seat 212 and the second half seat 213 can limit the two sides of the connecting plate 223, so that the plug-in block 222 is in a position aligned with the first plug-in connector 12, so as to facilitate accurate plug-in matching. The elastic member 24 is preferably a spring.

[0054] Of course, in embodiments not shown in the figures, the elastic member may be disposed only between the connecting plate and the first half seat, or only between the connecting plate and the second half seat.

[0055] like Figures 4 to 7 As shown, the connecting plate 223 includes a plate body 2231 and a folded edge 2232 arranged at the edge of the plate body 2231. The folded edge 2232 prevents the edge of the connecting plate 223 from being scratched against the first half seat 212 and the second half seat 213 during movement. At the same time, the folded edge 2232 allows the side of the plate body 2231 to have more surface area, so that the connecting plate 223 can better contact with the first half seat 212 and the second half seat 213, thereby improving the stability of the movement of the connecting plate 223.

[0056] like Figures 4 to 7 As shown, the first half seat 212 includes a first fixed plate 2121 and a first vertical plate 2122 disposed on the first fixed plate 2121, and the folded edge 2232 is movably connected to the first vertical plate 2122 through a first fastener 41. The second half seat 213 includes a second fixed plate 2131 and a second vertical plate 2132 disposed on the second fixed plate 2131, and the folded edge 2232 is movably connected to the second vertical plate 2132 through a second fastener 42. In this way, the connecting plate 223 can be movably connected to the first vertical plate 2122 through the first fastener 41, and the connecting plate 223 can be movably connected to the second vertical plate 2132 through the second fastener 42. During the movement of the connecting plate 223, the first fastener 41 and the second fastener 42 simultaneously guide and restrict the connecting plate 223 to prevent the second connector 22 from being deflected and offset from the preset moving track during the movement.

[0057] In order to make the elastic member 24 produce a damping effect on the movement of the connecting plate 223 or a more stable thrust, there are two elastic members 24. One elastic member 24 is arranged between the plate body 2231 and the first fixing plate 2121, and the other elastic member 24 is arranged between the plate body 2231 and the second fixing plate 2131. Preferably, in order to limit the radial movement of one spring, the plate body 2231 and the first fixing plate 2121 are detachably connected by a first bolt, and one spring is sleeved outside the first bolt. In order to limit the radial movement of another spring, the plate body 2231 and the second fixing plate 2131 are detachably connected by a second bolt, and the other spring is sleeved outside the second bolt.

[0058] like Figures 2 to 7 As shown, the first fastener 41 includes a first connecting column 411, a first guide column 412 and a first stopper head 413 connected in sequence. The diameter of the first guide column 412 is larger than the diameter of the first connecting column 411, the first connecting column 411 is connected to the folded edge 2232, the first vertical plate 2122 is provided with a first oblong hole 2123 for the first guide column 412 to pass through, the first stopper head 413 is stopped outside the first oblong hole 2123, and the size of the first stopper head 413 is larger than the width of the first oblong hole 2123. The second fastener 42 includes a second connecting column 421, a second guide column 422 and a second limiting head 423 which are connected in sequence. The diameter of the second guide column 422 is larger than the diameter of the second connecting column 421. The second connecting column 421 is connected to the folded edge 2232.
