[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1 - Figure 5 This embodiment of an interlocking LED display screen includes a display screen body 1. A splicing mechanism is installed on the back of the display screen body 1. The splicing mechanism facilitates the splicing of LED displays and improves the use of LED displays. An adjustment mechanism is provided on the back of the display screen body 1 to facilitate the adjustment of the hanging hole spacing and improve the hanging placement of LED displays. The splicing mechanism includes a housing 23, which is fixedly installed on the back of the display screen body 1. The housing 23 is used to support the sliding of a slider 22. A slider 22 is slidably provided on the inner wall of the housing 23. The slider 22 is used to support the insertion of an insert 26. An insert 26 is fixedly installed on one end of the slider 22. The insert 26 is used to insert into a slot 27. One end of the insert 26 penetrates the surface of the housing 23. A push block 25 is fixedly installed on the surface of the slider 22. The push block 25 pushes the slider 22 to move linearly along the inner wall of the housing 23.

[0028] The adjustment mechanism includes a frame 31, which is fixedly installed on the back of the display screen body 1. The frame 31 is used to support the installation of the rotating rod 32. The rotating rod 32 is rotatably connected to the inner wall of the frame 31 through a bearing. By setting the rotating rod 32 with positive and negative threads, it is easy to drive the limit blocks 35 on both sides to slide in a straight line towards each other along the inner wall of the frame 31. The rotating rod 32 is provided with positive and negative threads, and the limit blocks 35 are threadedly connected to the rotating rod 32. The limit blocks 35 slide on the inner wall of the frame 31. A receiving block 33 is fixedly installed on the limit block 35. The receiving block 33 has a hanging hole. By setting the receiving block 33 with the hanging hole, it is easy to suspend and install the LED display screen.

[0029] The box 23 is square in shape, and the cross-sectional shape of the insert 26 is a right triangle. The insert 26 is designed to be inserted into the slot 27.

[0030] There are two sliders 22, and a spring 24 is fixedly installed between the two sliders 22. The spring 24 is used to apply force to the insert block 26, so that the insert block 26 can be inserted into the slot 27.

[0031] There are two push blocks 25, and each push block 25 is square in shape. The push blocks 25 are used to move the slider 22.

[0032] A support plate 28 is fixedly installed on the back of the display screen body 1. A screw rod 29 is threaded onto the support plate 28. The screw rod 29 is set horizontally and is used to drive the mounting block 21 to slide linearly along the back of the display screen body 1.

[0033] One end of the lead screw 29 is fixedly installed with a first handle 210, which is in the shape of a round plate. The other end of the lead screw 29 is rotatably connected to a mounting block 21 via a bearing. The mounting block 21 slides on the back of the display screen body 1. A slot 27 is provided on the mounting block 21. The slot 27 is in the shape of a square groove. The slot 27 is designed to receive the insertion of the plug 26.

[0034] One end of the rotating rod 32 passes through the frame 31 and is fixedly installed with a second handle 34. The second handle 34 is in the shape of a circular plate and is used to rotate the rotating rod 32.

[0035] When splicing LED displays, turn the first handle 210. The first handle 210 drives the lead screw 29 to rotate. When the lead screw 29 rotates, it is threadedly connected to the receiving plate 28, which will drive the mounting block 21 to slide linearly along the back of the display body 1 until the first handle 210 contacts the receiving plate 28. Then, insert the side of the second LED display with the housing 23 into the side of the first LED display with the mounting block 21. During the process of inserting the housing 23 between the two mounting blocks 21, the insert block 26 will be squeezed into the housing 23 until the insert block 26 moves into the slot 27. At this time, the insert block 26, under the action of the spring 24, will be inserted into the slot 27, thus completing the splicing and installation of the LED display. The operation is simple and convenient.

[0036] When the LED display needs to be suspended, the second handle 34 can be rotated according to the spacing between the hooks on the wall. The second handle 34 drives the rotating rod 32 to rotate. The rotating rod 32 is provided with positive and negative threads, which will drive the limiting blocks 35 on both sides to move towards each other along the inner wall of the frame 31. When the limiting blocks 35 on both sides move towards each other, they will drive the receiving blocks 33 on both sides to move towards each other until the hanging holes on the surface of the receiving blocks 33 on both sides move to a suitable spacing, so as to facilitate the insertion of the hooks, thereby realizing the suspension installation of the LED display.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
