[0018] 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.

[0019] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a semi-finished product storage shelf for LCD screen production, comprising a frame body 1, which serves as the supporting foundation for the entire shelf and is made of high-strength aluminum alloy to ensure structural stability. It is equipped with casters at the bottom. The frame body 1 has two sets, each with a shelf 2 fixedly connected to its top. The shelf 2 is designed with its front end tilted upwards to prevent the LCD screen from easily sliding out. It is made of wear-resistant and anti-static material to effectively protect the surface of the semi-finished LCD screen from damage. A vertical rod 3 is fixedly connected to the top rear end of the shelf 2. The vertical rod 3 has a rectangular structure and its surface is treated with... The shelves 2 are smoothed to ensure stable vertical movement. Four sets of shelves 2 are provided, connected at the rear by X-shaped connecting rods 4. These X-shaped connecting rods 4 are formed by two sets of metal rods hinged together, enhancing the connection strength and synchronous adjustment capability between the shelves 2. Each of the four sets of shelf 2 contact surfaces is equipped with a sponge pad 5. The sponge pad 5 is soft and elastic, preventing direct contact between the semi-finished products and the shelf 2, thus avoiding scratches. The tops of the lower three sets of shelf 2 are fixedly connected with stop blocks 6. These stop blocks 6 have an L-shaped structure and are located inside the shelf 2, providing lateral restraint for the placed semi-finished products and preventing direct contact with the uprights 3, thus avoiding damage to the liquid crystal display. The display screen is scratched. A fixing plate 7 is fixedly connected to the rear of the top set of shelves 2. The fixing plate 7 is a rectangular metal plate integrally constructed with the top set of shelves 2. A locking block 9 is elastically connected to the front of the fixing plate 7 via a compression spring 8. When the compression spring 8 is in its natural state, it can push the locking block 9 to remain extended, fixing the spacing between the four sets of shelves 2. A guide rod 10 is fixedly connected to the rear of the locking block 9. The guide rod 10 is coaxial with the locking block 9, ensuring the stability of the locking block 9 during movement and facilitating manual movement to release the locking block 9 from its limit. A slot 11 is provided at the rear of the upright 3, with slots 11 evenly spaced along the length of the upright 3. Block 9 provides multiple fixed positions, thereby changing the spacing between the four sets of shelves 2, thus contacting the top of the LCD screen and providing vertical limiting capability. The inner walls of the upper three sets of shelves 2 are slidably connected to the outer wall of the upright 3. One end of the compression spring 8 is fixedly connected to the front of the fixed plate 7, and the other end of the compression spring 8 is fixedly connected to the rear of the locking block 9. Through the opposing squeezing force between the compression spring 8 and the fixed plate 7, the locking block 9 is always locked on the inner wall of the slot 11 without being affected by external force. The guide rod 10 is slidably connected to the inner wall of the fixed plate 7.

[0020] Reference Figures 1-3A crossbeam 12 is fixedly connected to the inner wall of the right-side frame 1. The crossbeam 12 provides structural rigidity for the frame 1. An auxiliary rod 13 is fixedly connected to the left side of the crossbeam 12. The auxiliary rod 13 maintains the stability of the lateral movement of the two sets of frame 1 and serves as a guide. A crossbeam 2 14 is fixedly connected to the inner wall of the left-side frame 1. The crossbeam 2 14 has the same structure as the crossbeam 12 and is at the same horizontal height. A rack 15 is fixedly connected to the right side of the crossbeam 2 14. The rack 15 has a uniform tooth pitch and meshes with a gear 16. The length of the rack 15 is the same as that of the auxiliary rod 13, providing a stroke for adjusting the lateral spacing between the two sets of frames 1. The rack 15 has a gear 16 meshing on the inner side of its outer wall. The number of teeth of the gear 16 matches that of the rack 15, enabling smooth transmission. By rotating the gear 16, the rack 15 is moved laterally, thereby changing the spacing between the two sets of frames 1. The outer wall of the auxiliary rod 13 passes through and is slidably connected to the inner wall of the second cross frame 14. The rack 15 passes through and is slidably connected to the inner wall of the first cross frame 12. The gear 16 is rotatably connected to the inner wall of the first cross frame 12.

[0021] Reference Figures 3-5 A rotating shaft 17 is fixedly connected to the center of gear 16. The rotating shaft 17 is coaxial with gear 16 to achieve synchronous rotation and is used to extend the connection between gear 16 and the limiting structure. A guide block 19 is elastically connected to the inner wall of the rotating shaft 17 through a limiting spring 18. The limiting spring 18 is always in a stationary state, providing downward tension to the guide block 19. The guide block 19 is square, so it can slide vertically on the inner wall of the rotating shaft 17 and also drive the rotating shaft 17 to rotate. A knob 20 is fixedly connected to the top of the guide block 19. The surface of the knob 20 is provided with anti-slip texture for easy manual rotation by the operator. A limiting block 21 is fixedly connected to the bottom of the knob 20. The limiting block 21 is provided in two opposing sets for opposing engagement with the limiting groove 22 to improve... For stability, a limiting groove 22 is provided at the top of the cross frame 12. The limiting groove 22 matches the limiting block 21, and several sets are provided for multiple locking of the limiting block 21. The rotation angle of the rotating shaft 17 and the gear 16 is fixed. The rotating shaft 17 is rotatably connected to the inner wall of the cross frame 12. One end of the limiting spring 18 is fixedly connected to the bottom inner wall of the rotating shaft 17, and the other end of the limiting spring 18 is fixedly connected to the bottom of the guide block 19. Through the opposing pressing force between the limiting spring 18 and the rotating shaft 17, the limiting block 21 is always locked on the inner wall of the limiting groove 22 without being affected by external force. The guide block 19 is slidably connected to the inner wall of the rotating shaft 17, and the limiting block 21 is locked on the inner wall of the limiting groove 22.

[0022] Working principle: When the LCD screen is temporarily stored, the LCD screens are placed one by one on the top of the shelf 2, and their ends are in contact with the stop block 6 on the inner side of the top of the shelf 2. Then, the guide rod 10 is manually pulled backward to pull the locking block 9. The compression spring 8 is compressed, and the locking block 9 is released from the locking slot 11. Then, the shelf 2 is moved up and down. The shelf 2 slides along the smooth vertical rod 3. At the same time, the X-shaped connecting rod 4 at the rear extends and retracts synchronously, ensuring the connection strength between the four sets of shelf 2 while realizing synchronous adjustment. When the upper set of shelf 2 contacts the top of the LCD screen, the guide rod 10 is released, the compression spring 8 returns to its original position and pushes the locking block 9 to lock into the corresponding locking slot 11 again, thus completing the fixing of the LCD screen.

[0023] When the widths of the LCD screens are different, pull up the knob 20, and the guide block 19 slides along the inner wall of the rotating shaft 17. The limiting spring 18 is stretched, and the limiting block 21 disengages from the limiting groove 22. Rotate the knob 20, and the rotating shaft 17 and the coaxially fixed gear 16 will rotate through the guide block 19. The gear 16 meshes with the rack 15 on the right side of the second cross frame 14, driving the rack 15 to move laterally, thereby causing the two sets of frames 1 to move inward or outward. At the same time, the auxiliary rod 13 on the left side of the first cross frame 12 slides along the inner wall of the second cross frame 14 to ensure the stability of the lateral movement of the two sets of frames 1. When the spacing is adjusted to the target width, release the knob 20, and the limiting spring 18 will return to its original position, pulling the limiting block 21 into the corresponding limiting groove 22, fixing the position of the gear 16, and completing the locking of the spacing between the two sets of frames 1.
