Description

Technical Field

[0001] This utility model relates to the field of display screen splicing technology, specifically to an adjustment mechanism for display screen splicing. Background Technology

[0002] A display screen is an electronic device used to display visual information. Through the control of internal circuitry, it converts signals into image elements, forming a picture that people can see. Display screens are widely used in various electronic devices.

[0003] The main functions of display screen splicing include improving display effects, enhancing user experience, and meeting various application needs. A splicing screen combines multiple displays to form a large-screen display system.

[0004] For example, a splicing display screen with application number 202322173300.7 uses a positioning mechanism and a lifting mechanism to facilitate the accurate positioning of the spliced ​​display screens, enabling workers to assemble them quickly, improving installation efficiency, and providing stable fixation for the assembled display screens, thus enhancing stability and safety during use. However, this device still has certain shortcomings.

[0005] It can only stabilize and fix the display screen when splicing. When the display screen is used separately, it cannot fix the horizontal direction of the display screen, resulting in poor stability when the display screen is fixed separately.

[0006] Therefore, we propose an adjustment mechanism for display screen splicing to solve the problems mentioned above. Utility Model Content

[0046] Please see Figure 9 This utility model provides a technical solution: an adjustment mechanism for display screen splicing, including an electromagnetic block 26. The difference between this embodiment and embodiment one is that:

[0047] The fixing mechanism includes an electromagnetic block 26. The electromagnetic block 26 is installed on the upper surface of the connecting rod 14.

Then the display screen is clamped by the limiting plate 19, and finally the vertical direction of the display screen is fixed by the first sliding strip 10 above, thereby realizing the separation and fixing of the display screen, which is more time-saving and labor-saving.

[0048] Working principle: When using the adjustment mechanism for splicing displays, firstly, when splicing displays is required, the displays are placed on the left and right sides of the second slide bar 11, respectively. The second servo motor 15 is started, which drives the transmission shaft 16 to rotate. The transmission shaft 16 drives the movable plate 17 to rotate. The movable plate 17 drives the limiting plate 19 to move relative to each other through the connecting bar 21. The limiting plate 19 completes the splicing and fixing of the two displays. The first servo motor 6 is started, which drives the left and right lead screws 7 to rotate through the output shaft. The left and right lead screws 7 drive the first slider 8 and the second slider 9 to move relative to each other or in opposite directions. The first slider 8 and the second slider 9 drive the first slide bar 10 below to move. The first slide bar 10 is moved to a position that is convenient for installing the display. Finally, the height adjustment mechanism 4 moves the first slide bar 10 downward to abut against the display, completing the vertical fixing of the display, thereby realizing the splicing and fixing of the display.

[0049] When it is necessary to separate and fix the display screen, place the display screen on the left and right sides of the second sliding strip 11 respectively. Adjust the limiting block 23 on the movable sleeve 22 to be located on the front surface of the movable sleeve 22. Then move the movable sleeve 22 so that the limiting block 23 on the movable sleeve 22 abuts against the display screen. The fixing mechanism completes the fixing of the limiting block 23. Then, the limiting plate 19 clamps the display screen. Finally, the first sliding strip 10 above completes the vertical fixing of the display screen, thereby realizing the separation and fixing of the display screen. The fixing method of the limiting plate 19 and the first sliding strip 10 for fixing the display screen is the same as the principle of separating and fixing the display screen described above. Thus, a series of operations are completed. The contents not described in detail in this specification are prior art known to those skilled in the art.
