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.

[0037] like Figures 1 to 3 , Fig.14As shown, the plug-in assembly of the LED display device of this embodiment includes: a first pair of plug-ins 10, a second pair of plug-ins 20 and an intermediate structure 30. The second pair of plug-ins 20 are arranged at intervals from the first pair of plug-ins 10. The intermediate structure 30 is arranged between the first pair of plug-ins 10 and the second pair of plug-ins 20, and the intermediate structure 30 includes a third pair of plug-ins 31 and a fourth pair of plug-ins 32 arranged at intervals and a driving member 33 for driving the third pair of plug-ins 31 and the fourth pair of plug-ins 32 to move, and the third pair of plug-ins 31 and the fourth pair of plug-ins 32 are connected by a wire 34. In this embodiment, the driving member 33 has an initial position and a push-up position. When the driving member 33 is in the initial position, the third pair of plug-ins 31 and the fourth pair of plug-ins 32 are close to each other, and the third pair of plug-ins 31 are separated from the first pair of plug-ins 10, and the fourth pair of plug-ins 32 are separated from the second pair of plug-ins 20. When the driving member 33 is in the push-up position, the third pair of plug-ins 31 and the fourth pair of plug-ins 32 are away from each other, and the third pair of plug-ins 31 is plugged with the first pair of plug-ins 10, and the fourth pair of plug-ins 32 is plugged with the second pair of plug-ins 20.

[0038] By applying the technical solution of this embodiment, the first pair of plug-ins 10 and the second pair of plug-ins 20 can be respectively installed on two adjacent LED boxes, so that the second pair of plug-ins 20 are spaced apart from the first pair of plug-ins 10. The intermediate structure 30 is arranged between the first pair of plug-ins 10 and the second pair of plug-ins 20, and the intermediate structure 30 includes a third pair of plug-ins 31 and a fourth pair of plug-ins 32 spaced apart and a driving member 33 for driving the third pair of plug-ins 31 and the fourth pair of plug-ins 32 to move, and the third pair of plug-ins 31 and the fourth pair of plug-ins 32 are connected by a wire 34. In this embodiment, the driving member 33 has an initial position and a push-up position. When the driving member 33 is in the initial position, the third pair of plug-ins 31 and the fourth pair of plug-ins 32 are close to each other, and the third pair of plug-ins 31 is separated from the first pair of plug-ins 10, and the fourth pair of plug-ins 32 is separated from the second pair of plug-ins 20. When the driving member 33 is in the push-up position, the third pair of plug-ins 31 and the fourth pair of plug-ins 32 are away from each other, and the third pair of plug-ins 31 is plugged into the first pair of plug-ins 10, and the fourth pair of plug-ins 32 is plugged into the second pair of plug-ins 20. The first pair of plug-ins 10, the second pair of plug-ins 20 and the intermediate structure 30 can integrate the power cord and the data cord and can realize on and off. In this way, by setting the movable third pair of plug-ins 31 and the fourth pair of plug-ins 32 between the LED boxes, the third pair of plug-ins 31 can be plugged with the first pair of plug-ins 10, and the fourth pair of plug-ins 32 can be plugged with the second pair of plug-ins 20 to realize communication. The plugging and separation of the intermediate structure 30 with the first pair of plug-ins 10 and the second pair of plug-ins 20 replaces the power cord and data cord at the adjacent parts. The connection is simple, so that the back of the spliced ​​LED box is tidy, and the staff can easily disconnect the connection, which improves the safety of operation. Therefore, the technical solution of this embodiment can solve the problem of unsafe conditions caused by the back of the LED box being full of wires in the related art. Furthermore, the first pair of plug-ins 10, the second pair of plug-ins 20 and the intermediate structure 30 can replace the wire connection between the boxes in the related art, and realize the function of fast connection of power and signals between the boxes after the overall assembly of the LED display device is completed, thereby realizing on-off control at 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.

[0039] It should be noted that the third pair of plug-ins 31 and the fourth pair of plug-ins 32 approach each other and the third pair of plug-ins 31 and the fourth pair of plug-ins 32 move away from each other are approaching each other in terms of relative distance, that is, the distance between the third pair of plug-ins 31 and the fourth pair of plug-ins 32 when the third pair of plug-ins 31 and the fourth pair of plug-ins 32 approach each other is less than the distance between the third pair of plug-ins 31 and the fourth pair of plug-ins 32 when the third pair of plug-ins 31 and the fourth pair of plug-ins 32 move away from each other. In the process of the third pair of plug-ins 31 and the fourth pair of plug-ins 32 approaching each other or moving away from each other, in order to prevent the wire 34 from being torn off, the wire 34 of this embodiment is relatively loose or elastic.

[0040] The driving member drives the third pair of plug-ins 31 and the fourth pair of plug-ins 32 to move in a linear manner.

[0041] Specifically, the first pair of plug-ins 10 and the second pair of plug-ins 20 both have plastic parts, power copper pins, signal copper pins, power wire welding positions and signal PCB welding positions.

[0042] The third pair of plug-ins 31 and the fourth pair of plug-ins 32 both have power copper pins, signal copper pins, guide posts, power wire welding positions, and signal PCB welding positions. The power copper pins are used to plug into the power copper holes of the plug-ins. The signal copper pins are used to plug into the signal copper holes of the plug-ins. The power wire welding positions are used to weld wires to connect to the power supply inside the LED display device. The signal PCB welding positions are used to weld the PCB and realize the connection between the welding connector on the PCB and the signal inside the LED display device.

[0043] like Figures 2 to 5 , Fig.12 and Fig.13 As shown, the intermediate structure 30 further includes a separator 35 for separating the third pair of plug-ins 31 and the fourth pair of plug-ins 32. The driving member 33 is rotatably disposed on the separator 35. When the third pair of plug-ins 31 and the fourth pair of plug-ins 32 approach each other, the separator 35 is disposed so as to separate the third pair of plug-ins 31 and the fourth pair of plug-ins 32, thereby preventing the third pair of plug-ins 31 and the fourth pair of plug-ins 32 from continuing to approach each other and colliding.

[0044] like Figures 2 to 5 , Fig.12 and Fig.13 As shown, the separator 35 includes a separator 351 disposed between the third pair of plug-ins 31 and the fourth pair of plug-ins 32 and a connecting plate 352 disposed on the separator 351. The driving member 33 is rotatably disposed on the connecting plate 352. The wire 34 between the third pair of plug-ins 31 and the fourth pair of plug-ins 32 can pass through the hollow area of ​​the separator 351, and the hollow area of ​​the separator 351 can also avoid part of the driving member 33, so that the separator 351 and the part of the driving member 33 and the wire 34 do not interfere with each other, and the structure of the intermediate structure 30 is compact. The setting of the connecting plate 352 facilitates the support of the driving member 33, so that part of the driving member 33 can be smoothly extended into the hollow area of ​​the separator 351.

[0045] Specifically, the partition frame 351 includes a partition bottom plate, a first side plate and a second side plate arranged on both sides of the partition bottom plate, and a first partition vertical plate and a second partition vertical plate arranged between the first side plate and the second side plate. The first partition vertical plate and the second partition vertical plate are connected to the surface of the partition bottom plate at intervals, and the first side plate, the first partition vertical plate, the second partition vertical plate and the second side plate are sequentially located on the same surface of the partition bottom plate. A partial driving member (hereinafter referred to as the driving block 332) is located between the first partition vertical plate and the second partition vertical plate, a part of the wire 34 (signal line) is located between the first side plate and the first partition vertical plate, and another part of the wire 34 (power line) is located between the second partition vertical plate and the second side plate. In this way, the wire 34 and the partial driving member are respectively located in their own independent spaces to prevent the partial driving member from interfering with the wire 34 when rotating. The above-mentioned signal line is used for signal transmission; the power line is used for voltage and current transmission.

[0046] Specifically, in order to facilitate the partial driving member to extend between the first partition vertical plate and the second partition vertical plate, the connecting plate 352 includes a square hole plate connected to the first side plate and the second side plate and a rectangular plate nested in the hole of the square hole plate, and the driving member 33 is rotatably arranged on the rectangular plate.

[0047] like Figures 2 to 5 , Fig.12 and Fig.13 As shown, the driving member 33 includes a rotating shaft 331, a driving block 332 arranged at the first end of the rotating shaft 331, and an operating portion 333 arranged at the second end of the rotating shaft 331. The axis of the rotating shaft 331 is perpendicular to the moving direction of the third pair of plug-ins 31 or the fourth pair of plug-ins 32. The rotating shaft 331 is rotatably arranged in the connecting plate 352, and the driving block 332 can cooperate with the third pair of plug-ins 31 and the fourth pair of plug-ins 32 to push and push to drive the third pair of plug-ins 31 and the fourth pair of plug-ins 32 away from each other. When the operating portion 333 is screwed, the rotating shaft 331 is driven to rotate, and the driving block 332 can rotate together, so that the driving block 332 can realize the pushing action. In order to facilitate processing and reduce the friction force on the third pair of plug-ins 31 and the fourth pair of plug-ins 32, the driving block 332 is in the shape of a flat key, and the operating portion 333 is a knob.

[0048] like Figures 2 to 5 , Fig.12 and Fig.13As shown, the intermediate structure 30 also includes a rotating sleeve 36 which is sleeved outside the rotating shaft 331 and fixed to the rotating shaft 331. The rotating sleeve 36 includes a sleeve body 361 located between the connecting plate 352 and the rotating shaft 331 and a stop plate 362 arranged at one end of the sleeve body 361 away from the operating part 333. The stop plate 362 and the operating part 333 are respectively located on both sides of the connecting plate 352. The rotating sleeve 36 separates the connecting plate 352 and the rotating shaft 331 to prevent the rotating shaft 331 from directly contacting the connecting plate 352 during rotation and causing wear, thereby increasing the service life of the rotating shaft 331. The stop plate 362 and the operating part 333 both cooperate with the connecting plate 352 to stop the rotating shaft 331 and prevent the rotating shaft 331 from moving along its axis so that the rotating shaft 331 can only rotate.

[0049] like Figure 7 and Fig.13 As shown, the intermediate structure 30 also includes a friction-reducing pad sleeved outside the sleeve body 361, so that the friction-reducing pad can separate the stop plate 362 and the connecting plate 352, prevent the stop plate 362 from directly contacting the connecting plate 352, and reduce the friction generated during the rotation of the rotating sleeve 36. The friction-reducing pad is preferably a plastic part.

[0050] like Figures 2 to 5 , Fig.12 and Fig.13 As shown, in the process of the driving member 33 switching from the push-up position to the initial position, in order to enable the third pair of plug-ins 31 and the fourth pair of plug-ins 32 to automatically move from positions away from each other to positions close to each other, the intermediate structure 30 also includes an elastic member 37 connected between the third pair of plug-ins 31 and the fourth pair of plug-ins 32. The elastic member 37 applies an elastic force to the third pair of plug-ins 31 and the fourth pair of plug-ins 32, so that the third pair of plug-ins 31 and the fourth pair of plug-ins 32 move from positions away from each other to positions close to each other. When the third pair of plug-ins 31 contacts the upper end surface of the partition frame 351, and the fourth pair of plug-ins 32 contacts the lower end surface of the partition frame 351, the third pair of plug-ins 31 and the fourth pair of plug-ins 32 are in positions close to each other. The elastic member 37 is preferably a tension spring, and the above-mentioned elastic force is a tension force.

[0051] Specifically, in order to make the tension applied by the elastic member to the third pair of plug-ins 31 and the fourth pair of plug-ins 32 more uniform, there are two elastic members 37, one of which is connected to the third pair of plug-ins 31 and the fourth pair of plug-ins 32 and is located between the first side plate and the first partition plate. The other elastic member 37 is connected to the third pair of plug-ins 31 and the fourth pair of plug-ins 32 and is located between the second partition plate and the second side plate.

[0052] like Figures 6 to 12As shown, the intermediate structure 30 also includes a locking member 38 movably arranged on the driving member 33. The first locking portion 353 and the second locking portion 354 are arranged at intervals on the partition 35. When the driving member 33 is in the push-up position, the locking member 38 can be locked and matched with the first locking portion 353. In this way, the third pair of plug-ins 31 is kept at a position for plugging with the first pair of plug-ins 10, and the fourth pair of plug-ins 32 is kept at a position for plugging with the second pair of plug-ins 20, and it is not easy to loosen, which ensures that the third pair of plug-ins 31 can be reliably plugged with the first pair of plug-ins 10, and the fourth pair of plug-ins 32 can be reliably plugged with the second pair of plug-ins 20, so as to maintain a good contact effect and avoid poor contact. When the driving member 33 is in the initial position, the locking member 38 can be locked and matched with the second locking portion 354. In this way, the third pair of plug-ins 31 is kept at a position for separation from the first pair of plug-ins 10, and the fourth pair of plug-ins 32 is kept at a position for separation from the second pair of plug-ins 20, and it is not easy to loosen, avoiding danger caused by misoperation.

[0053] Specifically, for the convenience of screwing and operation, the locking member 38 includes a stud, the first locking portion 353 includes a first screw hole, and the second locking portion 354 includes a second screw hole.

[0054] like Figures 2 to 13 As shown, the intermediate structure 30 also includes a fixing plate 391 and two limiting folding plates 392 arranged at both ends of the fixing plate 391. A part of the partition 35 is fixed at the middle position of the fixing plate 391. The third pair of plug-ins 31 and the fourth pair of plug-ins 32 are both located between the two limiting folding plates 392. The fixing plate 391 and the two limiting folding plates 392 limit the third pair of plug-ins 31 and the fourth pair of plug-ins 32, and guide the linear movement of the third pair of plug-ins 31 and the fourth pair of plug-ins 32, so that the third pair of plug-ins 31 is aligned with the first pair of plug-ins 10, and the fourth pair of plug-ins 32 is aligned with the second pair of plug-ins 20, so that the third pair of plug-ins 31 can be quickly plugged with the first pair of plug-ins 10, and the fourth pair of plug-ins 32 can be quickly plugged with the second pair of plug-ins 20. The fixing plate 391 and the two limiting folding plates 392 arranged at both ends of the fixing plate 391 are plastic parts of an integrated structure.

They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0061] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0062] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
