[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figures 1-6 As shown in the figure, this application provides an LED splicing display screen, including:

[0030] The connecting frame 1 comprises connecting plates 101, a plurality of connecting plates 101 are connected to form a rectangular connecting frame 1, a plurality of butt plates 102 are arranged in a circular array on the connecting plate 101, and the butt plate 102 is provided with a plug-in slot 103 on the side facing the middle of the connecting plate 101;

[0031] The mounting plate 2 is provided with a through slot 201 on one side, a sliding block 202 for blocking the through slot 201 is slidingly mounted on the mounting plate 2, and a plurality of LED lamp beads are uniformly mounted on one side of the sliding block 202 and the mounting plate 2; when the sliding block 202 moves and blocks the through slot 201, the LED lamp beads on the sliding block 202 and the mounting plate 2 are just laid on the same side,

[0032] The positioning mechanism comprises a plug-in plate 3 slidingly mounted on the mounting plate 2 in a circular array, which is used for plugging into the plug-in slot 103, and a connecting piece 4 acting on the plug-in plate 3 is mounted on the sliding block 202; when the sliding block 202 moves to be completely plugged into the through slot 201, the plurality of plug-in plates 3 are respectively plugged into the plurality of plug-in slots 103 through the connecting piece 4; when the sliding block 202 moves towards the corresponding connecting plate 101, the plurality of plug-in plates 3 are slidingly separated from the corresponding plug-in slot 103 through the connecting piece 4; that is, in use, the mounting plate 2 is first placed on one side of the connecting plate 101, and then the sliding block 202 is pressed; when the sliding block 202 moves, the plurality of plug-in plates 3 can move into the corresponding plug-in slot 103 through the connecting piece 4, so that the plurality of plug-in plates 3 are respectively plugged into the corresponding plug-in slot 103, thereby completing the rapid installation of the mounting plate 2; at this time, the sliding block 202 just blocks the sliding block 202; when one of the mounting plates 2 needs to be disassembled for maintenance or replacement, the sliding block 202 is pressed to move towards the connecting plate 101, and then the plurality of plug-in plates 3 are moved away from the corresponding plug-in plate 3 through the connecting piece 4, so that the plurality of plug-in plates 3 are respectively separated from the corresponding plug-in slot 103, thereby completing the rapid disassembly of the mounting plate 2; the use is convenient, and compared with the prior art, when one of the mounting plates 2 needs to be disassembled, the plurality of plug-in plates 3 can be simultaneously separated from the corresponding plug-in slot 103 by pressing the sliding block 202, thereby achieving the purpose of disassembly, without the need to disassemble a plurality of LED display screens, and the disassembly is more convenient, thereby reducing the labor of personnel.

[0033] As Figures 1-3As shown in the drawings, in some embodiments, the connecting member 4 includes a connecting rod 401 configured on one side of the sliding block 202, and a plurality of convex plates 402 are arranged in a circular array on the outer circumferential side of the connecting rod 401, the free ends of the convex plates 402 are hingedly connected with a plurality of connecting rods 403, and the plurality of connecting rods 403 are respectively hingedly connected with the plurality of plug-in plates 3. That is, when the sliding block 202 moves, the connecting rod 401 will be indirectly moved, because the connecting rod 401 is connected with the plurality of convex plates 402, so that the movement of the connecting rod 401 will drive the movement of the plurality of convex plates 402, and in turn drive the movement of the connecting rods 403 hingedly connected with the convex plates 402. Because one end of the connecting rod 403 is hingedly connected with the plug-in plate 3, when the convex plate 402 moves, the plurality of plug-in plates 3 will be away from or close to each other through the connecting rod 403, so that the plurality of plug-in plates 3 can be simultaneously separated from or inserted into the plug-in slot 103 of the device through the movement of the sliding plate, which is convenient to use.

[0034] As shown in the drawings, Figures 1-4 In some embodiments, the mounting plate 2 is provided with an elastic reset member acting on the connecting rod 401. When the connecting rod 401 is not driven by external force, the elastic reset member is used to reset the connecting rod 401 to block the through slot 201 of the sliding block 202. That is, through the elastic reset member, the sliding block 202 can always block the through slot 201 in the normal state, so that all the LED lamp beads are in the same plane, and the accidental movement of the sliding block 202 will not cause the movement of part of the LED lamp beads to affect the viewing experience.

[0035] As shown in the drawings, Figure 1 and Figure 2 In some embodiments, one side of the mounting plate 2 is provided with a support frame 5, and the elastic reset member includes a limiting convex block 6. The connecting rod 401 slides through the support frame 5 and is connected with the limiting convex block 6 at the free end. The design of the limiting convex block 6 can prevent the connecting rod 401 from sliding off the support frame 5, thereby playing a limiting role. The connecting rod 401 plays a guiding role, so that the sliding block 202 moves more smoothly. A reset spring 7 is sleeved on the connecting rod 401. One end of the reset spring 7 abuts against the plurality of convex plates 402, and the other end of the reset spring 7 abuts against the support frame 5. That is, in the normal state, the reset spring 7 is in a normal state at this time, and the sliding block 202 blocks the through slot 201. When the sliding block 202 is pressed, the sliding block 202 moves in the direction of the corresponding connecting plate 101, and the plug-in plate 3 is separated from the corresponding plug-in slot 103. When the sliding block 202 is released, the reset spring is elastically deformed, forcing the sliding block 202 to move until the limiting convex block 6 abuts against the support frame 5. At this time, the sliding block 202 blocks the through slot 201, and the reset of the sliding block 202 is completed quickly and accurately.

[0036] As shown in the drawings, Figure 1 and Figure 2As shown, in some embodiments, a plurality of guide rods 8 are mounted on the circular array of the connecting plate 101, and a plurality of guide cylinders 9 for the guide rods 8 to be inserted are mounted on the circular array of the mounting plate 2. The design of the guide rods 8 and the guide cylinders 9 plays a guiding and limiting role, so that after the guide cylinders 9 on the mounting plate 2 are sleeved on the guide rods 8, the mounting plate 2 is not easy to shake, the gap between the mounting plate 2 and the mounting plate 2 is also reduced, the error value is smaller, and the viewing experience is better when watching the LED spliced display screen.

[0037] As shown, Figure 2 In some embodiments, the connecting plate 101 is provided with an elastic assembly 10 acting on the corresponding mounting plate 2. When the plug-in plate 3 is separated from the plurality of plug-in slots 103, the mounting plate 2 is moved away from the connecting plate 101 by the elastic assembly 10. When the sliding block 202 is pressed to make the plurality of plug-in plates 3 separate from the plug-in slots 103, the mounting plate 2 can be moved away from the connecting plate 101 by the elastic assembly 10 at this time, which means that the mounting plate 2 will protrude after disassembly, facilitating the worker to take away the mounting plate 2 that needs to be disassembled.

[0038] As shown, Figure 2 In some embodiments, the elastic assembly 10 includes a rod body 1001 mounted on the connecting plate 101, a rotating frame 1002 rotatably sleeved on the rod body 1001, a torsional spring 1003 sleeved on the rod body 1001, one end of the torsional spring 1003 connected with the connecting plate 101, the other end of the torsional spring 1003 connected with the rotating frame 1002, a top ring 1004 slidably sleeved on the guide rod 8, and a transmission assembly 1005 mounted between the top ring 1004 and the rotating frame 1002. The rotating frame 1002 is rotated by the transmission assembly 1005 to convert the rotating force of the rotating frame 1002 into the moving force of the top ring 1004. That is, when the plug-in plate 3 is separated from the plurality of plug-in slots 103, the rotating frame 1002 is rotated by the elastic deformation characteristic of the torsional spring at this time, and the plurality of top rings 1004 are moved by the transmission assembly 1005, so that the plurality of sleeves are lifted by the plurality of top rings 1004. The plurality of top rings 1004 are indirectly lifted by the plurality of top rings 1004, and only one torsional spring 1003 is needed to make the mounting plate 2 be forced in multiple directions at the same time, so that the mounting plate 2 is lifted. It is more convenient to use.

[0039] As shown, Figure 1 and Figure 2As shown in the drawings, in some embodiments, the transmission assembly 1005 includes a plurality of moving plates 10051 which are circularly arranged and slidably mounted on the connecting plate 101, a transmission rod 10052 is hingedly connected between the moving plate 10051 and the top ring 1004, a plurality of drive rods 10053 are circularly arranged on the rotating frame 1002, and the free ends of the plurality of drive rods 10053 are respectively hingedly connected to the plurality of moving plates 10051. When the rotating frame 1002 rotates, the drive rods 10053 hingedly connected to the rotating frame 1002 will move, and because one end of the drive rod 10053 is hingedly connected to the moving plate 10051, when the rotating frame 1002 moves, the plurality of moving plates 10051 will move closer to or away from each other. Because the transmission rod 10052 is hingedly connected between the moving plate 10051 and the top ring 1004, the plurality of top rings 1004 will move synchronously, and the elastic force acting on the mounting plate 2 can be balanced by the torsional spring 1003, so that the mounting plate 2 can normally pop out and is not prone to jamming.

[0040] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in some embodiments, a through groove 201 is formed in the middle of one side of the mounting plate 2, the number of guide rods 8 is four, and they are respectively located at the corners of the connecting plate 101. The through groove 201 is indirectly arranged in the middle, and the sliding block 202 is also arranged in the middle. Specifically, the plug-in plates 3 are circularly distributed around the axis direction of the connecting rod 401, and each plug-in plate 3 is more uniformly stressed. The guide rods 8 are located at the corners of the connecting plate 101, and are more uniformly stressed, so that the use is more convenient.

[0041] As shown in the drawings, Figure 2 and Figure 5 As shown in the drawings, in some embodiments, a plurality of limiting plates 11 are formed on the mounting plate 2, the number of each limiting plate 11 is two, and a limiting groove 12 is formed on each opposite side. The limiting block 13 located in the limiting groove 12 is formed on both sides of the plug-in plate 3 in the length direction. The limiting groove 12 and the limiting block 13 play a guiding and limiting role, so that the plug-in plate 3 slides more smoothly when moving.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
