Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, and in particular to a fixing component for liquid crystal displays. Background Technology
[0002] A liquid crystal display (LCD) is a type of display that uses liquid crystals as the imaging medium. Under the influence of an electric field, the liquid crystal molecules change their alignment, thereby altering the polarization state of the polarized light passing through them. By controlling the arrangement of the liquid crystal molecules behind each pixel, the intensity of light passing through that pixel can be adjusted, thus forming an image. Fixing components ensure the stability of the LCD during installation and use, preventing screen displacement due to vibration or external forces, which could affect the display effect.
[0003] The mounting components for LCD screens in the prior art are usually designed with a fixed spacing, which limits their ability to adapt to screens of different sizes. The inability to adjust the spacing between the mounting plates will prevent them from adapting to LCD screens of different sizes and specifications, thus limiting the applicability of the components and making it impossible to install certain special-sized screens. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a fixing component for liquid crystal displays, which aims to improve the problem that the fixing components for liquid crystal displays in the prior art cannot adjust the spacing between mounting plates.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing component for a liquid crystal display screen, including a housing, a motor fixedly connected to the rear of the housing, a gear fixedly connected to the output end of the motor, fixing boxes fixedly connected to both sides of the interior of the housing, limit rods fixedly connected inside the two fixing boxes, limit blocks slidably connected to the exterior of the two limit rods, rack plates fixedly connected to the rear of the two limit blocks, gears meshing with each other on opposite sides of the two rack plates, connecting rods fixedly connected to the front of the two limit blocks, mounting plates fixedly connected to the front of the two connecting rods, and limit components fixedly connected to both sides of the two mounting plates, the limit components being used to limit the mounting plates.
[0006] Furthermore, both sides of the two mounting plates are fixedly connected to a fixing sleeve, and a circular plate is slidably connected inside the multiple fixing sleeves. One end of a movable rod is fixedly connected to one opposite side of the multiple circular plates, and a clamping plate is fixedly connected to the other end of the multiple movable rods. A pull rod is fixedly connected to the side of the multiple circular plates that is far apart from each other.
[0007] Furthermore, the limiting component includes hinge blocks and pulleys, with multiple hinge blocks fixedly connected to both sides of the mounting plate, and pulleys rotatably connected inside each of the multiple hinge blocks.
[0008] Furthermore, slide rails are provided on both sides of the interior of the outer casing, and multiple pulleys are slidably connected inside the slide rails.
[0009] Furthermore, each of the two pull rods is fixedly connected to a handle, and each of the two pull rods is fitted with a return spring.
[0010] Furthermore, one end of each of the plurality of reset springs is fixedly connected to the inside of the fixed sleeve, and the other end of each of the plurality of reset springs is fixedly connected to a circular plate.
[0011] Furthermore, multiple movable rods and pull rods are slidably connected inside the fixed sleeve, and two mounting plates are slidably connected to the inner sides of the outer casing.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this utility model, by starting the motor, the gear drives the rack plate to move, which in turn drives the limiting block to slide along the limiting rod, causing the connecting rod, mounting plate, hinge block and pulley to move in sequence, so as to realize the convenient adjustment of the mounting plate spacing, adapt to LCD screens of different sizes, and enhance the versatility and flexibility of the fixing components.
[0014] 2. In this utility model, by pulling the handle, the pull rod and the circular plate are moved, compressing the return spring. After the return spring deforms, it pushes the movable rod to slide inward, so that the clamping plate is separated to place the display screen. When the handle is released, the return spring returns to its elasticity, and the clamping plate closes to fix the display screen, realizing convenient and quick fixation of the display screen, which is stable and reliable, and can be assembled or repaired more quickly.

[0022] 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.
[0023] Reference Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of a fixing component for a liquid crystal display screen, including a housing 1. A motor 2 is fixedly connected to the rear of the housing 1, and a gear 3 is fixedly connected to the output end of the motor 2. Fixing boxes are fixedly connected to both sides of the interior of the housing 1. Limiting rods 6 are fixedly connected inside the two fixing boxes. Limiting blocks 5 are slidably connected to the exterior of the two limiting rods 6. A rack plate 4 is fixedly connected to the rear of the two limiting blocks 5. Gears 3 are meshed on opposite sides of the two rack plates 4. Connecting rods 7 are fixedly connected to the front of the two limiting blocks 5. Mounting plates 8 are fixedly connected to the front of the two connecting rods 7. Limiting components are fixedly connected to both sides of the two mounting plates 8. The limiting components are used to limit the mounting plates 8. The limiting components include hinge blocks 9 and pulleys 10. Multiple hinge blocks 9 are fixedly connected to both sides of the mounting plates 8. Pulleys 10 are rotatably connected inside the multiple hinge blocks 9. Slide rails 11 are provided on both sides of the interior of the housing 1. Multiple pulleys 10 are slidably connected inside the slide rails 11.
[0024] First, motor 2 is started, and its output immediately drives gear 3 to rotate. As gear 3 rotates, the two rack plates 4 are driven and move smoothly along the track. The movement of rack plates 4 further pulls the limiting block 5, allowing it to slide smoothly on the outside of the limiting rod 6. The function of the limiting rod 6 is to provide a guiding and limiting component, ensuring that the limiting block 5 can remain on the predetermined track when it slides smoothly on its outside, preventing it from deviating or leaving the track. The sliding action of the limiting block 5 is relayed to the connecting rod 7, triggering its corresponding movement. The function of the connecting rod 7 is to transmit power and motion. When the limiting block 5 slides, the connecting rod 7 moves accordingly, converting this motion into a safe movement. The precise displacement of mounting plate 8 ensures the coordinated movement of the entire system. The movement of connecting rod 7 further causes the precise displacement of mounting plate 8, driving hinge block 9 and pulley 10 to move synchronously. Pulley 10 slides efficiently within slide rail 11. By replacing sliding friction with rolling friction, friction during movement is reduced, improving movement efficiency and precision. Slide rail 11 provides a smooth and precise track for pulley 10, ensuring that pulley 10 can slide smoothly and precisely on it, thereby driving mounting plate 8 to move in parallel, maintaining the straightness of the movement trajectory, thus enabling the two mounting plates 8 to move in parallel inside the outer casing 1.
[0025] Reference Figure 1 and Figure 4 Both sides of the two mounting plates 8 are fixedly connected to the fixing sleeves 12. The inside of the fixing sleeves 12 is slidably connected to the circular plates 15. One end of the movable rod 17 is fixedly connected to the opposite side of the circular plates 15. The other end of the movable rod 17 is fixedly connected to the clamping plate 18. The side of the circular plates 15 that is far apart is fixedly connected to the pull rod 14. The outside of the two pull rods 14 is fixedly connected to the handle 13. The outside of the two pull rods 14 is fitted with a return spring 16. One end of the return spring 16 is fixedly connected to the inside of the fixing sleeve 12. The other end of the return spring 16 is fixedly connected to the circular plate 15. The movable rod 17 and the pull rod 14 are slidably connected to the inside of the fixing sleeve 12. The two mounting plates 8 are slidably connected to the inside sides of the outer shell 1.
[0026] Once the spacing of the mounting plates 8 is adjusted to the correct position, the operator can pull the two handles 13. As the handles 13 move, the pull rod 14 is driven, which in turn drives the circular plate 15 to move smoothly within the fixed sleeve 12. The movement of the circular plate 15 applies pressure to the return spring 16, causing it to elastically deform. The return spring 16 stores energy when compressed, and this energy is the source of the force required for the spring to return to its shape. Multiple circular plates 15 work together to push the movable rod 17 to slide into the fixed sleeve 12, causing the two clamping plates 18 to gradually separate, thus reserving space for the placement of the display screen. Next, the display screen to be installed is placed between the two clamping plates 18. When the operator releases the handles 13, the return spring 16 returns to its original shape, releasing the previously stored energy. During this process, it pushes the clamping plates 18 to slowly close, thereby firmly fixing the display screen. The force of the return spring 16 ensures that the clamping plates 18 can tightly fix the display screen placed therein, providing the necessary clamping force, thereby ensuring the stability and reliability of the display screen after installation.
[0027] Working principle: First, start motor 2. The output end of motor 2 drives gear 3 to rotate. When gear 3 rotates, it drives two rack plates 4 to move. When rack plates 4 move, they drive limit block 5 to slide outside limit rod 6. The movement of limit block 5 drives connecting rod 7 to move. The movement of connecting rod 7 drives mounting plate 8 to move. The movement of mounting plate 8 drives hinge block 9 and pulley 10 to move, so that pulley 10 slides inside slide rail 11. Under the action of multiple pulleys 10, the two mounting plates 8 slide to both sides inside the outer shell 1, realizing convenient adjustment of the distance between the two mounting plates 8. It can adapt to different sizes and types of LCD screens, making the fixing component more versatile and flexible. After the position between the two mounting plates 8 is adjusted, pull the two... A handle 13 moves, causing the pull rod 14 to move. The pull rod 14 moves, causing the circular plate 15 to move inside the fixed sleeve 12. When the circular plate 15 moves, it compresses the return spring 16, causing the return spring 16 to undergo elastic deformation. After the return spring 16 is compressed, the multiple circular plates 15 drive the movable rod 17 to slide into the fixed sleeve 12, thereby moving the two clamping plates 18 away from each other. Then, the display screen to be installed is placed between the two clamping plates 18, and the two handles 13 are released. Under the elastic action of the return spring 16, the two clamping plates 18 are moved closer together to install and fix the display screen. This makes it easy to fix the display screen, ensuring that the LCD screen is stable and reliable after installation, and enabling faster completion of product assembly or maintenance.
[0028] 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.
