The pixel array screen is composed of a large number of closely arranged pixels and has an extremely high pixel density. Pixel screen assembly brackets usually adopt a modular design and are composed of multiple identical or similar components. This design enables the brackets to combine and display the screens first.

[0003] Currently, an existing splicing device (such as patent number: CN220493354U) discloses a splicing display screen mounting rack. This mounting rack does not exert pressure on the display screen, will not affect the service life of the display screen, and avoids the problem that the frame of the profile splicing rectangular frame is not square, which may cause the display screen to not be installed.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: when assembling existing pixel screens, generally multiple screens are installed on a fixed rack, and the screens are assembled by connecting a splitter. However, when actually installing the mounting rack, there may be a certain positional deviation, and the position of the installed pixel screen is not adjustable, resulting in a certain deviation error in the spliced pixel screen, which affects the screen projection effect.

In this device, an adjusting plate 4 and a positioning rod 5 that can be finely adjusted after installation are provided. After installing the pixel screen, the position of the pixel screen can be finely adjusted according to the actual installation requirements of the mounting frame 1, so that each pixel screen can be assembled together more completely, ensuring the beauty after assembly.

[0022] Embodiment

[0023] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As described above, the technical solution in the embodiment of the present application is to effectively solve the technical problem that when assembling existing pixel screens, generally multiple screens are installed on a fixing frame, and a screen splitter is connected to assemble the screens. However, when actually installing the mounting frame 1, there may be a certain positional deviation, and the position of the pixel screen after installation cannot be adjusted, resulting in a certain deviation error in the spliced pixel screen, affecting the screen projection effect. The general idea is as follows: A pixel array display splicing device includes a mounting frame 1. The number of mounting frames 1 is two. An adjusting mechanism for facilitating the splicing of pixel screens is provided on the mounting frame 1. The adjusting mechanism includes a threaded rod 2, a pulling plate 3, an adjusting plate 4, and a positioning rod 5. When a user installs a pixel screen, the pixel screen can be placed between two C-shaped rods 43 and fixed in the threaded mounting holes on the second connecting rod 41 by screws. When installing the mounting frame 1, the mounting frame 1 can be placed in the area to be fixed and installed through the threaded holes on the mounting block 12;

[0024] Circular grooves 13 are respectively formed at the side ends of the opposite surfaces of the two mounting frames 1. The threaded rod 2 is rotatably installed on the inner side walls of the two circular grooves 13. A positioning rod 5 is fixedly installed at the side end of the adjusting plate 4. A slider 52 is fixedly installed at the side end of the positioning rod 5. A threaded groove 53 is formed through the upper end of the slider 52. The threaded rod 2 is threadedly rotatably installed on the inner side wall of the threaded groove 53. Two first connecting rods 11 are fixedly installed between the two mounting frames 1. Two mounting blocks 12 are respectively fixedly installed at the ends of the two mounting frames 1. A plurality of limiting grooves 14 are further formed at the upper end of the lower mounting frame 1. An annular plate 21 is fixedly installed at the circumferential end of the threaded rod 2. A cylindrical groove 22 is formed through the upper end of the annular plate 21. The pulling plate 3 is located at the upper end of the annular plate 21. A limiting column 31 is fixedly installed at the lower end of the pulling plate 3. The limiting column 31 is slidably installed through the inner side wall of the cylindrical groove 22. Two springs 32 are fixedly installed between the pulling plate 3 and the annular plate 21. After the mounting frame 1 is installed, it may be necessary to finely adjust the position of the adjusting plate 4 according to the actual installation position of the mounting frame 1 to facilitate better splicing of the pixel screen on the adjusting plate 4. The user can pull the pulling plate 3 upward. The upward movement of the pulling plate 3 drives the limiting column 31 to move upward and leave the inner side wall of the limiting groove 14. At this time, the spring 32 is stretched;

[0025] A plurality of second link rods 41 are fixedly installed at both end portions on both sides of the adjusting plate 4. Fixed rods 42 are fixedly installed at the side end portions of the second link rods 41 on both sides. C-shaped rods 43 are fixedly installed at the side end portions of the two fixed rods 42. Two movable rings 51 are fixedly installed at the side end portion of the positioning rod 5. The two movable rings 51 are both slidably installed on the circumferential end portions of the two first link rods 11. After the limiting post 31 moves upward and leaves the inner wall of the limiting groove 14, the user can rotate the annular plate 21 forward or reversely. The rotation of the annular plate 21 drives the threaded rod 2 to rotate. The rotation of the pulling plate 3 drives the slider 52 to move upward or downward through the threaded groove 53. The movement of the slider 52 drives the adjusting plate 4 to move upward or downward through the positioning rod 5, and further drives the pixel screen to move upward or downward through the C-shaped rods 43 on both sides, so as to finely adjust the position of the pixel screen after the mounting frame 1 is installed.

[0026] Aiming at the problems existing in the prior art, the utility model provides a pixel array display splicing device. By providing an adjusting plate 4 and a positioning rod 5 that can be finely adjusted after installation, the device can finely adjust the position of the pixel screen according to the actual installation requirements of the mounting frame 1 after the pixel screen is installed, so that each pixel screen can be assembled together more completely, ensuring the beauty after assembly.

[0027] Working principle:

[0028] When the user installs the pixel screen, the pixel screen can be placed between two C-shaped rods 43 and fixed in the threaded mounting holes on the second connecting rod 41 through screws. When installing the mounting frame 1, the mounting frame 1 can be placed in the area to be fixed and installed through the threaded holes on the mounting block 12. After the mounting frame 1 is installed, it may be necessary to finely adjust the position of the adjusting plate 4 according to the actual installation position of the mounting frame 1 to facilitate better splicing of the pixel screen on the adjusting plate 4. The user can pull the pull plate 3 upward. When the pull plate 3 moves upward, the limit post 31 moves upward and leaves the inner wall of the limit groove 14. At this time, the spring 32 is stretched. After the limit post 31 moves upward and leaves the inner wall of the limit groove 14, the user can rotate the annular plate 21 forward or reversely. When the annular plate 21 rotates, the threaded rod 2 rotates. The rotation of the pull plate 3 drives the slider 52 to move upward or downward through the thread groove 53. The movement of the slider 52 drives the adjusting plate 4 to move upward or downward through the positioning rod 5, and then drives the pixel screen to move upward or downward through the C-shaped rods 43 on both sides, realizing fine adjustment of the position of the pixel screen after the mounting frame 1 is installed. When assembling the existing pixel screens, generally multiple screens are installed on a fixed frame and assembled through a connecting splitter. However, when actually installing the mounting frame 1, there may be a certain position deviation, and the position of the installed pixel screen cannot be adjusted, resulting in a certain deviation error in the spliced pixel screen, affecting the screen projection effect. This device is provided with an adjusting plate 4 and a positioning rod 5 that can be finely adjusted after installation. After the pixel screen is installed, the position of the pixel screen can be finely adjusted according to the actual installation requirements of the mounting frame 1, so that each pixel screen can be assembled more completely together, ensuring the beauty after assembly. Moreover, this device is provided with a pull plate 3, a limit post 31 and a limit groove 14 that cooperate with each other. After the adjustment of the pixel screen is completed, the position of the threaded rod 2 can be limited by inserting the limit post 31 into the limit groove 14, ensuring the stability of the threaded rod 2 and avoiding the possibility of shaking of the pixel screen after installation, with good stability.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
