Description

Technical Field

[0001] This utility model relates to the field of display screen bezel splicing technology, specifically to a bezel splicing structure for a liquid crystal display screen. Background Technology

[0002] Currently, the bezel structure of spliced ​​LCD displays often requires the inclusion of protective bezels in its design. These protective bezels primarily protect the outer surfaces of the LCD screen, providing a certain level of protection. Even if the thickness of the protective bezel is made as thin as possible, it inevitably increases the gap at the splicing points. Furthermore, without protective bezels, the LCD screen lacks sufficient protection when used alone, increasing the risk of damage.

[0003] Currently, the protective bezels on LCD screens require precise alignment of multiple bezel components during the splicing process. If the splicing device lacks precise guidance and limiting mechanisms, or if the tolerances of the splicing components are large, it can easily lead to inaccurate alignment between the bezel and the LCD screen, resulting in positioning errors. In addition, in some traditional splicing structures, the way to connect the bezel and the LCD screen may be too simple, such as relying on a single buckle or fixing point, lacking effective sliding, adjustment, or limiting designs. This means that the bezel is not adequately fixed and supported after splicing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a frame splicing structure for a liquid crystal display screen, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A frame splicing structure for a liquid crystal display screen includes two horizontal frames and two vertical frames. Both ends of the two horizontal frames are provided with horizontal mounting grooves. A horizontal sliding groove is provided in the horizontal mounting groove. A mounting shaft is slidably installed in the horizontal sliding groove. A connecting bracket rod is fixedly installed on the mounting shaft. Both ends of the two vertical frame pieces are provided with vertical mounting slots, and the inner sides of the two horizontal frame pieces and the two vertical frame pieces are fixedly installed with clips, and the clips are provided with clip slots. Adjustment components are provided on both of the horizontal frames.

[0006] Preferably, the two horizontal frames are arranged front to back, and the two vertical frames are arranged left to right, with the horizontal and vertical frames connected by connecting rods.

[0007] Preferably, the adjustment assembly includes two mounting plates fixedly installed on the horizontal frame, bearings fixedly installed on the mounting plates, a bidirectional lead screw fixedly installed on the bearings, and symmetrically arranged L-shaped sliding plates movably installed on the bidirectional lead screw.

[0008] Preferably, a sliding groove is provided on the horizontal frame, and a T-shaped sliding plate is slidably installed inside the sliding groove.

[0009] Preferably, an adjusting rod is fixedly installed on the side end face of the T-shaped slide plate, and a fitting groove is provided at the end of the adjusting rod away from the T-shaped slide plate.

[0010] Preferably, the L-shaped slide plate is fixedly mounted on the T-shaped slide plate, the end of the adjusting rod away from the T-shaped slide plate extends into the interior of the transverse slide groove, and the fitting groove fits into the mounting shaft.

[0011] Preferably, a U-shaped frame plate is fixedly installed on the horizontal frame and on the outside of the mounting plate, and the two ends of the bidirectional lead screw are respectively rotatably installed on the two U-shaped frame plates.

[0012] Preferably, a hexagonal rotating block is fixedly installed on the bidirectional lead screw, and the hexagonal rotating block is positioned between the two mounting plates.

[0013] This utility model provides a bezel splicing structure for a liquid crystal display screen. Compared with the prior art, it has the following advantages: 1. This utility model places the LCD screen between two horizontal bezels and two vertical bezels, and pushes the two vertical bezels to move inward. When the vertical bezels move inward, the vertical bezels will drive the two horizontal bezels to move inward through the cooperation of the connecting rod and the mounting shaft and the limiting of the mounting shaft and the horizontal sliding groove. By moving the two vertical bezels and the two horizontal bezels inward at the same time, the precise positioning of the LCD screen is effectively achieved, avoiding errors and misalignments during splicing, thereby improving the use effect of the bezel splicing structure. 2. In this utility model, when the two vertical bezels are preferentially attached to the LCD screen, the hexagonal rotating blocks on the two horizontal bezels are rotated respectively. The hexagonal rotating blocks drive the bidirectional lead screw to rotate, and the L-shaped sliding plate on the bidirectional lead screw will move inward. When the L-shaped sliding plate moves, it will synchronously drive the adjusting rod on the T-shaped sliding plate to move. When the adjusting rod does not limit the mounting shaft, the mounting shaft on the connecting rod will slide in the horizontal sliding groove. By sliding the mounting shaft in the horizontal sliding groove, the horizontal bezel is continuously pushed, which can effectively make the slot on the horizontal bezel fit with the LCD screen, ensuring the positioning and stability of the LCD screen.

[0017] Please see Figure 1-4 This utility model is a frame splicing structure for a liquid crystal display screen, including two horizontal frame 1 and two vertical frame 2. Both ends of the two horizontal frame 1 are provided with horizontal mounting grooves 3, and horizontal sliding grooves 4 are provided in the horizontal mounting grooves 3. Mounting shafts 5 are slidably installed in the horizontal sliding grooves 4, and connecting brackets 6 are fixedly installed on the mounting shafts 5. Both ends of the two vertical frame 2 are provided with vertical mounting grooves 7. The inner sides of the two horizontal frame 1 and the two vertical frame 2 are fixedly installed with locking blocks 8, and locking slots 9 are provided on the locking blocks 8. The two horizontal frame 1 are arranged front and back, and the two vertical frame 2 are arranged left and right. The horizontal frame 1 and the vertical frame 2 are connected by connecting brackets 6, wherein the number of connecting brackets 6 is the fourth, and the two horizontal frame 1 and the two vertical frame 2 are on the same horizontal plane.

[0018] In this embodiment, the LCD screen is placed between two horizontal frame 1 and two vertical frame 2. The two vertical frame 2 are pushed to move inward. When the vertical frame 2 moves inward, the two horizontal frame 1 will move inward through the cooperation of the connecting rod 6 and the mounting shaft 5 and the limiting of the mounting shaft 5 and the horizontal slide groove 4. By moving the two vertical frame 2 and the two horizontal frame 1 inward at the same time, the precise positioning of the LCD screen is effectively achieved, avoiding errors and misalignments during splicing, thereby improving the use effect of the frame splicing structure.

[0019] Adjustment components are provided on both horizontal frame sides 1. Each adjustment component includes two mounting plates 10 fixedly installed on the horizontal frame side 1. Bearings 11 are fixedly installed on the mounting plates 10, and double-acting lead screws 12 are fixedly installed on the bearings 11. Symmetrically arranged L-shaped sliding plates 13 are movably installed on the double-acting lead screws 12. A sliding groove 14 is provided on the horizontal frame side 1. A T-shaped sliding plate 15 is slidably installed inside the sliding groove 14. An adjusting rod 16 is fixedly installed on the side end face of the T-shaped sliding plate 15. A fitting groove 17 is provided at the end of the adjusting rod 16 away from the T-shaped sliding plate 15. The L-shaped sliding plate 13 is fixedly installed on the T-shaped sliding plate 15, and the adjusting rod 16 is located away from the T-shaped sliding plate. One end of 15 extends into the interior of the transverse sliding groove 4. The fitting groove 17 fits against the mounting shaft 5. A U-shaped frame plate 18 is fixedly installed on the transverse frame 1 and outside the mounting plate 10. The two ends of the bidirectional screw 12 are respectively rotatably installed on the two U-shaped frame plates 18. A hexagonal rotating block 19 is fixedly installed on the bidirectional screw 12. The hexagonal rotating block 19 is positioned between the two mounting plates 10. The adjusting rod 16 is slidably installed inside the transverse sliding groove 4, and the adjusting rod 16 is in contact with the mounting shaft 5 through the fitting groove 17. When the adjusting rod is fixed on the mounting shaft 5, the mounting shaft 5 will not move within the transverse sliding groove 4, but can only rotate.

[0020] In this embodiment, when the two vertical frame blocks 2 are preferentially attached to the LCD screen, the hexagonal rotating blocks 19 on the two horizontal frame blocks 1 are rotated respectively. The hexagonal rotating blocks 19 drive the bidirectional lead screw 12 to rotate, and the L-shaped sliding plate 13 on the bidirectional lead screw 12 will move inward. When the L-shaped sliding plate 13 moves, it will synchronously drive the adjusting rod 16 on the T-shaped sliding plate 15 to move. When the adjusting rod 16 does not limit the mounting shaft 5, the mounting shaft 5 on the connecting rod 6 will slide in the horizontal sliding groove 4. By sliding the mounting shaft 5 in the horizontal sliding groove 4, the horizontal frame block 1 is continuously pushed, which can effectively make the slot 9 on the horizontal frame block 1 fit on the LCD screen, ensuring the positioning and stability of the LCD screen.

[0021] Working principle: During use, the adjusting rod 16 is fixed to the mounting shaft 5. Simultaneously, the mounting shaft 5 is rotatably mounted to the adjusting rod 16 via the fitting groove 17. The LCD screen is placed between the two horizontal frame 1s and the two vertical frame 2s, pushing the two vertical frame 2s inward. When the vertical frame 2s move inward, the vertical frame 2s, through the cooperation of the connecting rod 6 and the mounting shaft 5, and the limiting action of the mounting shaft 5 and the horizontal sliding groove 4, drive the two horizontal frame 1s to move inward. By simultaneously moving the two vertical frame 2s and the two horizontal frame 1s inward, precise positioning of the LCD screen is effectively achieved. When the two vertical frame 2s preferentially fit... When assembling the LCD screen, rotate the hexagonal rotating blocks 19 on the two horizontal bezels 1 respectively. The hexagonal rotating blocks 19 drive the bidirectional lead screw 12 to rotate, and the L-shaped sliding plate 13 on the bidirectional lead screw 12 will move inward. When the L-shaped sliding plate 13 moves, it will synchronously drive the adjusting rod 16 on the T-shaped sliding plate 15 to move. When the adjusting rod 16 does not limit the mounting shaft 5, the mounting shaft 5 on the connecting bracket 6 will slide in the horizontal sliding groove 4. By sliding the mounting shaft 5 in the horizontal sliding groove 4, the horizontal bezel 1 is continuously pushed, which can effectively make the slot 9 on the horizontal bezel 1 fit against the LCD screen, ensuring the positioning and stability of the LCD screen.
