[0002] A liquid crystal display board, also known as a liquid crystal drive board, is a circuit board specifically designed to drive a liquid crystal display and display images. Its main functions include receiving image signals from a signal source, processing these signals to optimize the display effect, and transmitting the processed signals to the liquid crystal screen to achieve image display.

[0003] In current technical practices, the firm connection between the liquid crystal display board module and the support frame often relies on traditional fasteners such as screws. During the assembly or disassembly process, operators need to apply appropriate torque to ensure that the screws tightly lock the liquid crystal display board components. However, this mechanical force transmission may cause subtle stress accumulation on the precision circuit board, potentially leading to performance degradation or damage risks.

Installation boxes 3 are installed at the front end and the rear end of the liquid crystal screen board card main body 2. Two connecting plates 4 are fixedly connected to the top of the mounting plate 1. A clamping plate 5 is fixedly connected to the top of the connecting plate 4. Two clamping buckles 6 are slidably connected inside the installation box 3. Elastic springs 7 are fixedly connected to the opposite surfaces of the clamping buckles 6. A clamping groove 8 is formed on the surface of the clamping plate 5. Limiting grooves 9 are formed on both sides of the installation box 3. A threaded rod 10 is threadedly connected inside the limiting groove 9. A rotating plate 11 is fixedly connected to the end of the threaded rod 10 away from the installation box 3. When the staff needs to disassemble and repair the liquid crystal screen board card main body 2, the rotating plate 11 is rotated inward to make the threaded rod 10 abut against the clamping buckle 6 and move it, so that the clamping buckle 6 is disengaged from the clamping groove 8 and at the same time the liquid crystal screen board card main body 2 is released from the limit; after the repair is completed, the clamping buckle 6 inside the installation box 3 is aligned with the clamping groove 8 and buckled in. After the buckling is completed, the elastic force of the elastic spring 7 makes the clamping buckle 6 firmly fixed in the clamping groove 8, so that the liquid crystal screen board card main body 2 is completed for installation. The setting of the movable clamping connection can effectively prevent the existing screw fixation from damaging the liquid crystal screen board card main body 2, and the operation is simple, which can effectively improve the work efficiency.

The number of the elastic sheets 12 is two, and the end close to the rotating plate 11 is fixedly connected to the rotating plate 11. Through the setting of the elastic sheets 12, the threaded rod 10 can form a firm limit during the process of being rotated out, preventing the threaded rod 10 from falling off due to excessive rotation and affecting the normal disassembly of the liquid crystal screen board card main body 2.

[0025] Referring to Figure 3 As shown, in this embodiment: Sliding grooves 13 are formed at the front end and the rear end inside the installation box 3. Sliding blocks 14 are fixedly connected to the front end and the rear end of the clamping buckle 6. The inside of the sliding groove 13 is slidably connected to the sliding block 14. Through the setting of the sliding groove 13 and the sliding block 14, a firm guiding effect can be formed when the clamping buckle 6 moves inside the installation box 3, thereby improving the installation and disassembly efficiency of the mounting plate 1 and the liquid crystal screen board card main body 2.

[0026] Referring to Figure 5As shown in the figure, in this embodiment: a friction plate 15 is mounted on the surface of the buckle 6.

[0030] Working principle: When the staff needs to disassemble and repair the LCD panel card main body 2, rotate the rotating plate 11 inward to make the threaded rod 10 press against the buckle 6 and move it, so that the buckle 6 is disengaged from the card slot 8 and at the same time the LCD panel card main body 2 is released from the limit; after the repair is completed, align the buckle 6 inside the installation box 3 with the card slot 8 and buckle it in. After the buckling is completed, the elastic force of the elastic spring 7 makes the buckle 6 firmly fixed in the card slot 8, so that the LCD panel card main body 2 is installed. The setting of the movable clamping connection can effectively prevent the existing screw fixation from damaging the LCD panel card main body 2, and the operation is simple, which can effectively improve the work efficiency. Through the setting of the elastic piece 12, the threaded rod 10 can form a firm limit during the process of turning out, preventing the threaded rod 10 from falling off due to excessive rotation and affecting the normal disassembly of the LCD panel card main body 2. Through the setting of the chute 13 and the slider 14, the buckle 6 can form a firm guiding effect when moving inside the installation box 3, thereby improving the installation and disassembly efficiency of the installation plate 1 and the LCD panel card main body 2. Through the setting of the friction plate 15, the buckle 6 can have a greater friction force when it is snapped into the card slot 8, thereby improving the fixing effect after the installation of the LCD panel card main body 2. Through the setting of the rounded corner 16, when the buckle 6 is pulled outwards, the edge of the buckle 6 and the edge of the rounded corner 16 are in sliding connection, which can make the process of pulling out the buckle 6 more labor-saving. Through the setting of the cooling fan 17, when the installation of the LCD panel card main body 2 is completed, starting the cooling fan 17 can achieve convenient heat dissipation of the LCD panel card main body 2 during use, effectively improving the service life of the LCD panel card main body 2. Through the setting of the reinforcing core 18, the installation box 3 can be fixed more firmly on the LCD panel card main body 2, preventing the installation box 3 from being worn and falling off due to long-term use, and improving the use experience.
