Description

Technical Field

[0001] This utility model relates to the field of display screen bezels, specifically to a double-sided LCD display screen bezel. Background Technology

[0002] With the development of the times, the application of LCD screens has become increasingly widespread. Traditional single-sided displays can no longer meet user needs in certain scenarios, so double-sided LCD screens have emerged. A double-sided LCD screen is a display device that can display images on both sides simultaneously. It achieves the function of synchronous or independent display of content on both sides by installing two sets of LCD display modules on each side of the bezel, greatly improving the flexibility of information display and space utilization. It is widely used in advertising, exhibitions and other fields.

[0003] While existing double-sided LCD screen bezels can secure and support the screen, the use of bolts or clips for fixing necessitates the use of tools during installation and disassembly, which is time-consuming and labor-intensive, impacting the ease of screen assembly and production efficiency. Therefore, this invention proposes a double-sided LCD screen bezel that facilitates installation and disassembly. Summary of the Invention

[0004] This utility model provides a double-sided LCD screen bezel. By using fixing blocks and limiting components at both ends of the side bezel to cooperate with the upper and lower bezels respectively, it solves the problem of cumbersome installation and disassembly of existing double-sided LCD screen bezels, which affects production efficiency.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In this embodiment, refer to Figure 1 - Figure 7 The specific implementation of the double-sided LCD screen bezel includes a bracket 1, an upper bezel 2, and a lower bezel 3. The upper bezel 2 and the lower bezel 3 are slidably installed on the upper and lower ends of the bracket 1 through a limiting structure 4. Side bezels 5 are provided on both sides of the bracket 1. The two ends of the side bezels 5 are respectively provided with fixing blocks 51 and limiting components 6 that cooperate with the upper bezel 2 and the lower bezel 3. The upper bezel 2 is provided with fixing grooves that cooperate with fixing blocks 51. The two ends of the lower bezel 3 are provided with limiting grooves that cooperate with limiting components 6. The front and rear ends of the bracket 1 are respectively provided with screen receiving grooves 11. The upper bezel 2, the lower bezel 3, and the side bezels 5 are all provided with limiting edges 7 that cooperate with screen receiving grooves 11.

[0025] In use, the two screens are placed into the screen receiving slots 11 respectively. Then, the upper frame 2 is installed on the bracket 1 through the limiting structure 4. The two ends of the upper frame 2 are fixed to the two sides of the bracket 1 by the cooperation of the fixing block 51 on the side frame 5 and the fixing slot. Then, the lower frame 3 is installed on the lower end of the bracket 1 through the limiting structure 4. The two ends of the lower frame 3 are tightly fixed to the side frame 5 by the cooperation of the limiting component 6 and the limiting slot, so that the frame forms a stable overall structure. After the frame is installed, the screen is firmly fixed in the screen receiving slot 11 by the limiting edge 7, thereby preventing the screen from shifting or being damaged during transportation or use.

[0026] The limiting assembly 6 includes a toggle block 61, a limiting post 62, and a return spring 63. The limiting post 62 is slidably mounted on one end of the side frame 5 via the return spring 63, and the toggle block 61 is fixedly mounted on one side of the limiting post 62. The side frame 5 has a mounting groove for mounting the limiting post 62 and the return spring 63. One side of the side frame 5 has a sliding groove 52 that cooperates with the toggle block 61. The sliding groove 52 communicates with the mounting groove. The toggle block 61 has a sliding block 611 that cooperates with the sliding groove 52. The limiting post 62 has a through groove that connects to the sliding block 611. Through the cooperation of the sliding groove 52 and the sliding block 611, the limiting post 62 slides smoothly while controlling the movement distance of the limiting post 62, thereby preventing the limiting post 62 from moving excessively and falling off.

[0027] In use, push the limiting post 62 with the toggle block 61 to compress the return spring 63 and move it into the mounting groove, thereby avoiding affecting the installation of the lower frame 3. After the lower frame 3 is installed in place, release the toggle block 61, and the limiting post 62 will automatically pop out under the action of the return spring 63 and lock into the limiting groove, thereby firmly locking both ends of the lower frame 3 and ensuring the stability of the overall structure.

[0028] One side of the side frame 5 is provided with a limiting part 53 that slides with the bracket 1. The bracket 1 is provided with a slot 12 that mates with the limiting structure 4 and the limiting part 53. Both the limiting part 53 and the limiting structure 4 are T-shaped blocks or dovetail blocks. The design of the T-shaped blocks or dovetail blocks can enhance the stability and firmness of the connection between the frame and the bracket 1. Both the T-shaped blocks and the dovetail blocks have good guiding and anti-slip capabilities, allowing the frame to slide only along the slot 12, thereby preventing the frame from shifting or misaligning during installation or disassembly. This design not only improves the assembly accuracy between the frame and the bracket 1, but also makes the frame stable and less prone to loosening when subjected to external forces.

[0029] In this embodiment, both the limiting part 53 and the limiting structure 4 are T-shaped blocks, and the slot 12 is a T-shaped groove. Through the design of the T-shaped block and the T-shaped groove, the precise fit between the frame and the bracket 1 is achieved, thereby avoiding any deviation of the frame during the installation process.

[0030] One side of the limiting edge 7 is provided with an elastic compression strip 8 that mates with the screen receiving groove 11. The elastic deformation of the compression strip 8 firmly secures the screen within the screen receiving groove 11, preventing displacement or damage to the screen when subjected to severe vibration or accidental impact. This ensures the screen remains stable under various usage environments, extending its lifespan.

[0031] The lower frame 3 has a circuit board receiving slot 31, which communicates with the screen receiving slot 11. This interconnected slot allows for quick connection between the circuit board and the screen, ensuring stable and efficient signal transmission. One side of the circuit board receiving slot 31 has several through holes for connecting to external devices, thus enabling connection between the screen and external devices. A cover plate 32 is also located on one side of the lower frame 3, attached to the circuit board receiving slot 31. The cover plate 32 is snap-fitted onto the lower frame 3. Its design facilitates circuit board installation and maintenance, effectively preventing dust and impurities from entering, thereby extending the circuit board's lifespan.

[0032] The beneficial effects of this utility model are as follows: By cooperating with the fixing block 51 and the limiting component 6 with the upper frame 2 and the lower frame 3 respectively, the frame can be quickly installed and disassembled, thereby simplifying the operation process and improving production efficiency. Furthermore, by cooperating with the limiting edge 7 and the screen receiving groove 11, the screen is confined within the screen receiving groove 11, thereby ensuring that the screen is not easily shaken during use and improving overall stability.
