Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a UV-resistant modular liquid crystal display screen. Background Technology

[0002] UV-resistant modular LCD screens are display devices that integrate UV protection. Through modular design, they enable flexible splicing and expansion of the screen while providing UV protection. They are widely used in display scenarios that require high flexibility and protection performance.

[0003] In existing technologies, LCD displays typically use fixed-size screen modules, which are spliced ​​together to achieve large-size displays. These screen modules are mechanically fixed within a frame and signal transmission is achieved through electrical connections. Furthermore, to prevent damage to the screen from ultraviolet (UV) rays and potential health effects on users, some displays employ special UV-protective coatings or filters. These coatings or filters absorb or reflect UV rays, thus protecting both the screen and the user from direct UV exposure.

[0004] Existing fixed-size screen modules often struggle to achieve seamless connections during assembly, resulting in suboptimal display quality. Furthermore, the protective effect of UV-resistant coatings or filters is limited, and their performance deteriorates easily due to wear and aging over long-term use. Screen protection measures are typically limited to surface coatings, lacking protection for the overall screen structure, making it susceptible to damage from external impacts. Therefore, this paper proposes a UV-resistant modular LCD display to address these issues. Utility Model Content

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.

[0029] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a UV-resistant modular LCD display screen, comprising a housing 1, which protects the internal modular screens 3 and provides an installation foundation and structural support for each component. The modular screens 3 are arranged on the inner side of the housing 1, serving as the core display part of the display screen for displaying images and information. Cable management holes are provided on the right side of the housing 1 to organize and guide the cables connecting the modular screens 3, avoiding cable clutter and ensuring the cleanliness of the display screen and the safety of the cables. The number of cable management holes is consistent with the number of modular screens 3, ensuring that the cables of each screen can pass through independently. The top and bottom of the modular screens 3 are both sloped. Multiple sets of modular screens 3 are arranged, and multiple sets of modular screens 3 contact each other through the slopes, realizing modular splicing, which facilitates expansion and maintenance.

[0030] Reference Figures 1-3 An adjustment assembly 2 is provided on the left side of the outer casing 1. The adjustment assembly 2 includes an extension block, which is fixedly connected to the left side of the outer casing 1 to provide an installation base and support for the threaded rod 202. The top of the extension block is rotatably connected to the threaded rod 202 via a bearing. A knob A201 is fixedly connected to the top of the threaded rod 202 for manually rotating the threaded rod 202. A slider 205 is threadedly connected to the surface of the threaded rod 202. A toothed plate 203 is fixedly connected to the front of the slider 205 to convert the rotational motion of the threaded rod 202 into the linear motion of the slider 205. A guide block is fixedly connected to the front of the slider 205, and a guide plate is provided on the back of the toothed plate 203. The guide groove 206 has an outer wall that slides with the inner wall of the guide block, which restricts the movement direction of the slider 205 and makes it move linearly along the guide groove 206. A rotating rod is rotatably connected through the left side of the outer shell 1. A driven gear 204 is fixedly connected to the surface of the rotating rod, which drives the driven gear 204 to rotate through the movement of the toothed plate 203. The front of the toothed plate 203 meshes with the back of the driven gear 204, which converts the linear motion of the toothed plate 203 into the rotational motion of the driven gear 204. A modular screen 3 is fixedly connected to the surface of the rotating rod, which drives the modular screen 3 to rotate through the rotation of the rotating rod. A protective component 4 is provided on the back of the outer shell 1.

[0031] Reference Figures 3-5 The protective component 4 includes a stud 401, one end of which penetrates the back of the housing 1 and is rotatably connected to a movable plate, for moving the movable plate by rotating the stud 401. The other end of the stud 401 is fixedly connected to a knob B402, for rotating the stud 401 manually. A baffle 405 is fixedly connected to the front of the movable plate, for blocking or exposing the modular screen 3 by moving the movable plate. The edge of the movable plate contacts the inner wall of the housing 1, for limiting the direction of movement of the movable plate. A guide rod 404 is fixedly connected to the back of the movable plate, the end of which penetrates the inner wall of the housing 1 and is fixedly connected to a limiting plate 403, for ensuring the stability of the direction of movement of the movable plate by the guiding action of the guide rod 404, while the limiting plate 403 limits the range of movement of the guide rod 404.

[0032] Reference Figure 3 , Figure 4 , Figure 6 The number of baffles 405 is twice the number of modular screens 3. Each group of two baffles 405 forms a set, with each set symmetrically distributed vertically. These baffles are used to shield and protect the top and bottom of the modular screens 3. Each set of baffles 405 has an adjacent side with a movable groove 407. A protective pad 406 is slidably connected to the inner wall of the movable groove 407. The protective pad 406 engages with the inclined surface of the modular screen 3 to provide cushioning and protection. The protective pad 406 is elastically connected to the inner wall of the movable groove 407 via a spring 408. The connection is as follows: one end of the spring 408 is fixedly connected to the inner wall of the movable groove 407, and the other end of the spring 408 is fixedly connected to the outer wall of the protective pad 406. This is used to enable the protective pad 406 to move elastically through the elastic action of the spring 408, thereby enhancing the protective effect. The number of protective pads 406 is the same as the number of baffles 405. The side of the protective pad 406 closest to the modular screen 3 is set with an angle. The modular screen 3 and the angle of the protective pad 406 are matched to achieve a better buffering and protective effect through the angled cooperation.

[0033] Working principle: The device adjusts the angle of the modular screen 3 through the adjustment component 2. When the angle of the modular screen 3 needs to be adjusted, the operator rotates the knob A201. The knob A201 drives the threaded rod 202 to rotate. Since the slider 205 is threadedly engaged with the threaded rod 202, the rotation of the threaded rod 202 causes the slider 205 to move downward along the thread direction. When the slider 205 moves, the guide block on its front slides in the guide groove 206 on the back of the toothed plate 203, thereby driving the toothed plate 203 to move along the direction of the guide groove 206. When the toothed plate 203 moves, it meshes with the driven gear 204, thereby driving the driven gear 204 to rotate. The driven gear 204 is fixed on the surface of the rotating rod, so the rotation of the driven gear 204 will drive the rotating rod to rotate. The modular screen 3 is fixedly connected to the surface of the rotating rod. The rotation of the rotating rod causes the angle of the modular screen 3 to change. Since multiple sets of modular screens 3 are connected to the rotating rod, the movement of the toothed plate 203 can drive multiple sets of driven gears 204 to rotate synchronously, thereby realizing the synchronous adjustment of the angle of multiple sets of modular screens 3.

[0034] When the modular screen 3 is rotated to a horizontally parallel position, the protective component 4 begins to function. The operator rotates knob B402, which drives stud 401 to rotate. When stud 401 rotates, due to its threaded engagement with the moving plate, the moving plate moves axially along stud 401. The movement of the moving plate causes the baffle 405 fixed on its front to move. When the baffle 405 moves to the appropriate position, it can shield and protect the top and bottom of the modular screen 3. When the baffle 405 moves to shield the modular screen 3, the modular screen 3 presses against the inclined surface of the protective pad 406, causing them to move away from each other on the inner wall of the movable groove 407 until the protective pad 406 contacts the modular screen 3. Since the protective pad 406 is elastically connected by spring 408, it can provide a buffering effect during the contact process, preventing the baffle 405 from directly colliding with the modular screen 3 and causing damage. At the same time, the protective pad 406 can also prevent dust, foreign objects, etc. from entering the gap between the modular screen 3 and the baffle 405, further protecting the modular screen 3.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
