Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display screen protection technology, and in particular to a liquid crystal display screen with a protective structure. Background Technology

[0002] An LCD screen is a device that uses the optical properties of liquid crystal molecules to display images. Its applications are extremely wide, covering various fields such as daily life, work, and industry. LCD screens require protection for two main reasons: firstly, the glass substrate on the screen surface has relatively low hardness and is easily scratched by hard objects; secondly, the internal liquid crystal layer may leak due to impacts or collisions, directly causing screen damage. Therefore, an LCD screen with a protective structure is needed. LCD screens with protective structures are protective devices that facilitate convenient and environmentally friendly use of the screen. However, in existing technologies, they often cannot be replaced in a timely manner when damaged, leading to a shortened lifespan. Utility Model Content

Specifically, the fixed column 16 provides fixed support for the display screen 1 and fixes the movable plate 17. When the movable plate 17 moves, the fixed column 16 can drive the display screen 1 to move.

[0020] Reference Figure 4 The inner wall of the movable plate 17 is fixedly connected to a rotating shaft 27, and the outer wall of the rotating shaft 27 is rotatably connected to a movable table 23. Specifically, the rotating shaft 27 fixes the movable plate 17, and the rotating shaft 27 rotates inside the moving platform 23.

Specifically, the movable platform 23 provides fixed support for the second motor 24, and when the second motor 24 is working, it drives the worm gear 25 to rotate through the output end.

[0022] Reference Figure 4 The toothed end of the worm 25 is meshed with a worm wheel 26, and the outer wall of the worm wheel 26 is fixedly connected to one end of the rotating shaft 27. Specifically, when the worm 25 rotates, it drives the worm wheel 26 to rotate through the tooth end. The worm wheel 26 fixes the rotating shaft 27. When the worm wheel 26 rotates, it drives the rotating shaft 27 to rotate inside the moving table 23.

[0023] Reference Figure 4 The inner wall of the moving platform 23 is slidably connected to a slide rod 22, and both ends of the slide rod 22 are fixedly connected to an L-shaped fixing plate 21. The outer wall of the L-shaped fixing plate 21 is fixedly connected to a background wall 18. Specifically, the L-shaped fixing plate 21 is fixed by the background wall 18, and the L-shaped fixing plate 21 provides fixed support for the slide rod 22. When the moving platform 23 moves up and down, the slide rod 22 can play a limiting role.

[0024] Reference Figure 4 The outer wall of the background wall 18 is fixedly connected to the first motor 19, and the output end of the first motor 19 is fixedly provided with a threaded rod 20. The outer wall of the threaded rod 20 is threadedly connected to the inner wall of the moving platform 23. Specifically, the background wall 18 serves to fix the first motor 19. When the first motor 19 is working, it can drive the threaded rod 20 at the output end to rotate. When the threaded rod 20 rotates, it will drive the moving table 23 to move up and down through the threads on its surface.

[0025] Working principle: When using this device, firstly, the second protective shell 11 is installed and slid into the inner wall of the display screen 1 to engage. Then, the first protective shell 2 is installed and slid into the outer wall of the display screen 1. At this time, the first protective shell 2 will slide into the interior of the second protective shell 11 through the latch 3. The latch 3 presses against the movable rod 12 inside the second protective shell 11. The movable rod 12 will retract through the second spring 13 on the inner wall of the second fixing block 14. When the latch 3 passes the movable rod 12... Afterwards, the movable rod 12 will rebound through the second spring 13 on the inner wall of the second fixed block 14. When it rebounds, the movable rod 12 will be limited by the third limiting block 15 to prevent excessive ejection and jamming. After rebounding, the movable rod 12 will engage with the buckle 3, thereby achieving a fixed connection between the second protective shell 11 and the first protective shell 2. After installation, the protective film 10 can be slid into the inner groove of the first protective shell 2 for engagement and fixation. After fixation, the other half of the first protective shell 2 can be slid in and installed on the other side of the protective film 10, and then engaged and fixed diagonally on the outer wall of the display screen 1 and the second protective shell 11. After the protective shell is installed, the first motor 19 can drive the threaded rod 20 at the output end to rotate. When rotating, the thread on the outer surface of the threaded rod 20 will drive the moving platform 23 to move up and down. The second motor 24 can also drive the worm gear 25 to rotate on the upper surface of the moving platform 23 through the output end. When the worm gear 25 rotates, it will drive the worm wheel 26 to rotate through the tooth end. When the worm wheel 26 rotates, it will drive the movable plate 17 to swing up and down through the rotating shaft 27. When swinging, it will drive the display screen 1 to swing up and down at the same time, thus breaking the limitation of the fixed shape and realizing flexible adjustment to improve the experience and comfort. When the protective film 10 needs to be replaced, the latch 3 can be pushed to slide on the inner wall of the first fixed block 8 by pressing the isolation block 9. When sliding, the latch 3 can be limited by the second limit block 7. At this time, the latch 3 will drive the slider 4 to slide past the movable rod 12. After passing, the pressure on the isolation block 9 is released, and the latch 3 can be pushed out by the first spring 6 inside the first protective shell 2. Then the first protective shell 2 slides out from the outer wall of the display screen 1, and the protective shell can be removed to take out the protective film 10. This device not only protects the display screen from external impacts, but also allows for flexible adjustments to enhance the user experience and comfort. If the protective film is damaged, it can be disassembled and removed, thus saving on repair and replacement costs.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
