DETAILED DESCRIPTION

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4 As shown, a light guide plate connection mechanism that is easy to disassemble involves pulling the second limiting plate 12 to drive the movable frame 11. The movable frame 11 drives the second extension rod 9 to gradually straighten the hinged first extension rod 8. When the hinged first extension rod 8 and the second extension rod 9 rotate and straighten within the connecting frame 7 and the movable frame 11 respectively, the second extension rod 9 stretches the elastic rubber column 10. When the second extension rod 9 loses external force and is pulled apart, the elastic force of the elastic rubber column 10 drives the second extension rod 9 back to its original position, thereby returning the second extension rod 9 and the first extension rod 8 to their original positions and causing the movable frame 11 to abut against the connecting frame 7. After the second extension rod 9 and the first extension rod 8 are pulled apart, the movable frame 11... Move the second limiting plate 12 away from the connecting frame 7, so that the second limiting plate 12 on the outside of the mounting plate 1 moves away from the mounting plate 1. Then place the light guide plate on the mounting plate 1. One end of the light guide plate is abutted and limited by the first limiting groove opened by the first limiting plate 2. Release the second limiting plate 12, and the second extension rod 9 loses the external force pulling. The elastic rubber column 10 pulls the second extension rod 9 under its own elastic force. The second extension rod 9 drives the hinged first extension rod 8 to return to its original position in the connecting frame 7 and the movable frame 11. The movable frame 11 drives the second limiting plate 12 to abut against the outside of the light guide plate. The second limiting groove opened by the second limiting plate 12 limits the light guide plate, so that the light guide plate is initially limited and installed on the mounting plate 1.

[0022] Example 2, as Figure 2 and Figure 3 As shown, a light guide plate connection mechanism that is easy to disassemble is described. After the light guide plate is placed on the mounting plate 1 and clamped by the second limiting plate 12, the movable plate 6 is pulled. The movable plate 6 drives the movable screw 4 to extend on the mounting plate 1 until one side of the movable plate 6 is flush with one side of the light guide plate. Then, the movable block 5 is pulled to drive the movable screw 4 to rotate on the movable plate 6. The movable block 5 rotates on the movable plate 6 based on the movable screw 4 to limit the light guide plate on one side. At this time, the rotating movable screw 4 will limit the thread on the threaded side and the thread of the arc groove opened in the limiting block 3 to each other, preventing the movable screw 4 from continuing to extend on the mounting plate 1. The friction between the light guide plate and the movable block 5 also prevents the movable block 5 from rotating back to its original position, thereby limiting and fixing the light guide plate on the mounting plate 1.

[0023] It should be noted that the utility model discloses a light guide plate connecting mechanism convenient to disassemble, when using, through pulling movable plate 6 and driving movable screw rod 4 to extend mounting plate 1, can adapt to the light guide plate of different width, through pulling second limiting plate 12 and driving movable frame 11, movable frame 11 drives second extension rod 9 and drives articulated first extension rod 8 to open between movable frame 11 and connecting frame 7 and stretch elastic rubber column 10, utilize elastic rubber column 10 self elastic force and pull second extension rod 9 and drive movable frame 11 and drive second limiting plate 12 to be clamped in the outside of light guide plate, the second extension rod 9 and first extension rod 8 of stretchable can adapt to the clamping of light guide plate of different length, and the overall application range of device is more extensive, and through pushing movable block 5 and driving movable screw rod 4 to rotate on movable plate 6 one side, the threaded side of movable screw rod 4 is separated from the arc-shaped slot of limiting block 3, at this time, movable plate 6 drives movable screw rod 4 not to be limited by mounting plate 1, and movable plate 6 drives movable screw rod 4 to be convenient to pull on mounting plate 1, and movable block 5 is not limited in the one side of light guide plate, and pulls the light guide plate and slides in the second sliding slot of second limiting plate 12, and the one end of light guide plate is separated from the first limiting slot of first limiting plate 2, until light guide plate is completely separated from second limiting plate 12 and mounting plate 1, so that light guide plate is conveniently disassembled.
