[0003] Most of the existing large curved LED splicing screens are installed by splicing small LED screens onto the back panel through bolts and other methods to form a larger LED screen. However, the existing installation methods such as bolts are relatively cumbersome, and the workload is too large for the splicing of larger LED screens, which greatly increases the workload of the staff and reduces the splicing efficiency of the large LED screens. Therefore, a large curved LED splicing screen mounting bracket is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a large curved LED splicing screen mounting bracket to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large curved LED splicing screen mounting bracket, comprising a back plate for mounting the large curved LED splicing screen mounting bracket, a vertical plate symmetrically fixedly connected to the side wall of the back plate, a limited position frame rotatably connected between the two vertical plates, and a rotating shaft between the vertical plate and the limit frame is located in the lower half of the structure, a placement groove is provided at the lower end of the inner part of the limit frame, and mounting grooves are symmetrically provided on both sides of the inner wall of the limit frame, a first spring is fixedly connected to the inside of the mounting groove, and the end of the first spring is fixedly connected to A moving block, which slides and extends to the outside of the mounting groove and is fixedly connected with a push plate, and anti-slip pads are fixedly connected to the opposite sides of the two push plates, a mounting hole is horizontally opened in one of the vertical plates, and a second spring is horizontally fixedly connected to the inside of the mounting hole, a clamping block is fixedly connected to the side of the second spring close to the limit frame, and the side of the clamping block away from the second spring extends to the outside of the mounting hole, and a connecting rod is fixedly connected to the side of the clamping block close to the second spring, and the end of the connecting rod slides and extends to the outside of the vertical plate, and a clamping groove is opened on the side of the limit frame close to the clamping block.

[0006] Preferably, a limiting block is symmetrically fixedly connected to the side wall of the clamping block, and a limiting groove is symmetrically provided on the inner wall of the mounting hole.

[0007] Preferably, the two limiting blocks symmetrically fixedly connected on the side wall of the clamping block are respectively slidably connected to the inside of two limiting grooves opened on the inner wall of the mounting hole.

[0008] Preferably, a plurality of strip blocks are symmetrically fixedly connected to the side walls of the moving blocks, and a plurality of strip grooves are symmetrically fixedly connected inside the mounting grooves.

[0011] Preferably, the top surfaces of the two push plates are both arc-shaped.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0013] When the large curved LED splicing screen mounting bracket needs to be spliced, the pull rod is first pulled toward the outside of the vertical plate, so that the card block fixedly connected to it is driven by the pull rod to shrink toward the inside of the mounting hole until the card block moves out of the card slot opened on the side wall of the limit frame, thereby releasing the limit on the limit frame, and then the limit frame is turned outward along the rotation axis between it and the vertical plate, and then the LED screen is snapped into the inside of the limit frame, and then the two push plates symmetrically arranged inside the limit frame will be squeezed by the LED screen, thereby compressing the first spring. , and at the same time, the first spring pushes the push plate and the anti-skid pad to squeeze the LED screen, thereby squeezing and limiting the LED screen to prevent it from sliding, and then the limit frame is flipped toward the vertical plate again. When the side wall of the limit frame contacts the card block, at this time, because one side of the card block is set in an arc shape, and the limit frame has limited contact with the arc side of the card block, as the limit frame continues to flip, the card block will be pushed by the limit frame to slide toward the inside of the installation hole until the card block is parallel to the card slot opened on the side wall of the limit frame. At this time, the second spring will push the card block to be connected to the inside of the card slot to limit the limit frame. Compared with the prior art, this device can facilitate the splicing and disassembly of the LED screen, thereby greatly improving the splicing efficiency of the LED and reducing the workload of the staff.

DETAILED DESCRIPTION

[0022] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0025] like Figures 1 to 5The main structure of the device shown is a back plate 1, and vertical plates 2 are symmetrically fixedly connected to the side walls of the back plate 1. A limit frame 3 is rotatably connected between the two vertical plates 2, and the rotation axis between the vertical plates 2 and the limit frame 3 is located in the lower half of the structure, thereby effectively enabling the upper half of the limit frame 3 to be flipped open, thereby facilitating the insertion of the LED screen into the interior of the limit frame 3. A placement groove 4 is provided at the lower end of the interior of the limit frame 3, and the size of the placement groove 4 is the same as that of the lower end of the LED screen, thereby effectively clamping and limiting the lower end of the LED screen, thereby further preventing the LED screen from shaking in the limit frame 3;

[0026] Both sides of the inner wall of the limit frame 3 are symmetrically provided with mounting grooves, and a first spring 5 is fixedly connected inside the mounting groove, and a moving block 6 is fixedly connected to the end of the first spring 5, and the moving block 6 slides and extends to the outside of the mounting groove and is fixedly connected to a push plate 7, and the top surfaces of the two push plates 7 are both arc-shaped, and multiple side walls of the moving blocks 6 are symmetrically fixedly connected with strip blocks 14, and multiple mounting grooves are symmetrically fixedly connected inside with strip grooves, and the two strip blocks 14 fixedly connected on the side walls of the moving block 6 are respectively slidably connected to the inside of the two strip grooves opened on the inner wall of the mounting groove, and the two strip blocks 14 fixedly connected on the side walls of the moving block 6 are respectively slidably connected to the inside of the two strip grooves opened on the inner wall of the mounting groove, so as to effectively limit the sliding direction of the moving block 6 The two push plates 7 are fixedly connected to the opposite sides with anti-skid pads 8. Thanks to the setting of the anti-skid pads 8, the LED screen is clamped to the inside of the limit frame 3, and then the two push plates 7 symmetrically arranged inside the limit frame 3 will be squeezed by the LED screen, thereby compressing the moving block 6 fixedly connected to the push plate 7 on the side close to the inner wall of the limit frame 3 and the first spring 5 fixedly connected to the side wall of the moving block 6, and shrinking them to the inside of the installation groove. At the same time, the moving block 6 fixedly connected to it and the push plate 7 fixedly connected to the side of the moving block 6 away from the first spring 5 and the anti-skid pad 8 fixedly connected to the side of the push plate 7 away from the moving block 6 are relatively pushed by multiple first springs 5 ​​to squeeze the two sides of the LED screen, so as to squeeze and limit the LED screen to prevent it from sliding.

[0027] A mounting hole 9 is horizontally opened in one of the vertical plates 2, and a second spring 10 is horizontally fixedly connected inside the mounting hole 9. A clamping block 11 is fixedly connected to a side of the second spring 10 close to the limit frame 3. A limiting block 13 is symmetrically fixedly connected to the side wall of the clamping block 11. A limiting groove is symmetrically opened on the inner wall of the mounting hole 9. Two limiting blocks 13 symmetrically fixedly connected on the side wall of the clamping block 11 are respectively slidably connected to the inside of two limiting grooves opened on the inner wall of the mounting hole 9. Two limiting blocks 13 fixedly connected on the side wall of the clamping block 11 are respectively slidably connected to the inside of two limiting grooves symmetrically opened on the inner wall of the mounting hole 9, so as to effectively limit the sliding direction of the clamping block 11. The side of the clamping block 11 away from the second spring 10 extends to the outside of the mounting hole 9. One side of the end of the clamping block 11 is arc-shaped. A connecting rod 12 is fixedly connected to the side of the clamping block 11 close to the second spring 10. The end of the connecting rod 12 slides and extends to the vertical plate 2 When the locking block 11 is moved out of the slot 15 on the side wall of the limit frame 3, the limit frame 3 is released from the position of the limit frame 3.

[0028] How it works

[0029] When using the large curved LED splicing screen mounting bracket, firstly slide and extend the connecting rod 12 to the outside of the vertical plate 2 and pull it toward the outside of the vertical plate 2, so as to drive the card block 11 fixedly connected to its end to shrink toward the inside of the mounting hole 9 through the connecting rod 12, until the card block 11 moves out of the card slot 15 opened on the side wall of the limit frame 3, so as to release the limit on the limit frame 3, and then flip the limit frame 3 outward along the rotating axis between the outside of the limit frame 3 and the two vertical plates 2, and then snap the LED screen into the inside of the limit frame 3, and then the two push plates 7 symmetrically arranged inside the limit frame 3 will be squeezed by the LED screen, so as to compress the moving block 6 fixedly connected to the side of the push plate 7 close to the inner wall of the limit frame 3 and the first spring 5 fixedly connected to the side wall of the moving block 6, and shrink them toward the inside of the mounting groove, and at the same time, through multiple The first spring 5 pushes the moving block 6 fixedly connected to it, the push plate 7 fixedly connected to the side of the moving block 6 away from the first spring 5, and the anti-slip pad 8 fixedly connected to the side of the push plate 7 away from the moving block 6 to squeeze the two sides of the LED screen, so as to squeeze and limit the LED screen to prevent it from sliding, and then the limit frame 3 is flipped toward the vertical plate 2 again. When the side wall of the limit frame 3 contacts the card block 11, at this time, because one side of the card block 11 is arc-shaped, and the limit frame 3 contacts the arc-shaped side of the card block 11 first, as the limit frame 3 continues to flip, the card block 11 will be pushed by the limit frame 3 to slide toward the inside of the mounting hole 9 until the card block 11 is parallel to the card slot 15 opened on the side wall of the limit frame 3. At this time, the second spring 10 will push the card block 11 to be clamped into the inside of the card slot 15 to limit the limit frame 3.
