[0023] The embodiment of the present application discloses an advertising light box clamping frame. Figure 1-5 , an advertising light box clamping frame, comprising a first horizontal frame 1, a first vertical frame 2, a second horizontal frame 3, a second vertical frame 4 and an advertising light box body 7, the first horizontal frame 1, the first vertical frame 2, the second horizontal frame 3 and the second vertical frame 4 are arranged in a mouth shape, the first horizontal frame 1, the first vertical frame 2, the second horizontal frame 3 and the second vertical frame 4 are symmetrically slidably installed with fixed plates 12 inside, and two adjacent fixed plates 12 are fixedly connected in an L shape, and the first horizontal frame 1 and the first vertical frame 2 are each provided with a driving component for driving the fixed plate 12 to move;

[0024] The driving assembly includes a connecting shaft 16 and a bidirectional screw 11. The connecting shaft 16 is rotatably installed inside the first horizontal frame 1 and the first vertical frame 2. A worm 14 is sleeved on the side wall of the connecting shaft 16. A bidirectional screw 11 is provided inside the first horizontal frame 1 and the first vertical frame 2. The two ends of the bidirectional screw 11 are respectively threadedly installed inside the two fixed plates 12. A worm wheel 15 meshing with the worm 14 is sleeved on the side wall of the bidirectional screw 11. One end of the connecting shaft 16 movably passes through the first horizontal frame 1 and the second vertical frame 4 and is fixedly connected to the knob 8.

[0025] The interior of the second horizontal frame 3 and the second vertical frame 4 are both provided with a limiting assembly for limiting the fixed plate 12, and the limiting assembly includes a connecting rod 5 and a fixed block 17. The interior of the second horizontal frame 3 and the second vertical frame 4 are both provided with a connecting plate 20 movably provided by a spring 21. One side of the fixed plate 12 inside the second horizontal frame 3 and the second vertical frame 4 is fixedly connected with a tooth plate 18, and one side of the connecting plate 20 is symmetrically fixedly connected with a latching tooth 19 engaged with the tooth plate 18. One end of the connecting rod 5 is rotatably connected to the side wall of the connecting plate 20, the connecting rod 5 is located in the spring 21, and the fixed block 17 is fixedly connected to the side wall of the connecting rod 5. A fixing groove 9 that slides with the fixed block 17 is provided on one side of the second horizontal frame 3 and the second vertical frame 4;

[0026] A plurality of card plates 6 are fixedly mounted on opposite sides of the first horizontal frame 1 and the second horizontal frame 3, and the advertising light box body 7 is located inside the plurality of card plates 6;

[0027] The implementation principle of the advertising light box clamping frame of the embodiment of the present application is as follows: when in use, the connecting rod 5 on the second horizontal frame 3 and the second vertical frame 4 can be pulled to drive the connecting plate 20 to move, and the connecting plate 20 can drive the latching teeth 19 thereon to move. When the latching teeth 19 move to no longer contact with the tooth plate 18, the fixing block 17 on the connecting rod 5 can also be disengaged from the fixing groove 9. Then, the connecting rod 5 is rotated counterclockwise so that the fixing block 17 fits the side walls of the second horizontal frame 3 and the second vertical frame 4. The connecting rod 5 can be loosened, and the bottom of the advertising light box body 7 can be placed in the middle position of the upper surface of the first horizontal frame 1. By rotating the knob 8 on the first horizontal frame 1, the connecting shaft 16 on it can be driven to rotate. The connecting shaft 16 can drive the bidirectional screw 11 to rotate through the worm 14 and the worm gear 15. The bidirectional screw 11 can drive the two fixing plates 12 inside the first horizontal frame 1 to approach each other, thereby driving the first vertical frame 2 and the second vertical frame 4 to approach each other. At the same time, the two fixing plates 12 in the second horizontal frame 3 will also approach each other. The first vertical frame 2 and the second vertical frame 4 can be tightly fixed to the left and right sides of the advertising light box body 7. At the same time, the multiple card plates 6 on the first horizontal frame 1 can also be attached to the front and rear sides of the advertising light box body 7. By rotating the knob 8 on the first vertical frame 2, the bidirectional screw 11 inside it can be driven to rotate, thereby driving the two fixing plates 12 in the first vertical frame 2 to approach each other, thereby The first horizontal frame 1 and the second horizontal frame 3 can be fixed to the top and bottom of the advertising light box body 7, and the multiple card plates 6 on the second horizontal frame 3 can also be fitted to the front and rear sides of the advertising light box body 7. Finally, the connecting rod 5 is rotated clockwise to align the fixing block 17 with the fixing groove 9. After loosening the connecting rod 5, the connecting plate 20 can be driven to move and reset under the elastic force of the spring 21. The latch teeth 19 on the connecting plate 20 can be engaged with the tooth plate 18. At the same time, the fixing block 17 can also be moved into the fixing groove 9, thereby limiting the fixing plate 12 inside the second horizontal frame 3 and the second vertical frame 4 to ensure the stability of the entire device. In this process, the knob 8 on the first horizontal frame 1 can be rotated to It drives the two fixing plates 12 inside it to approach each other, thereby driving the first vertical frame 2 and the second vertical frame 4 to approach each other to fix the left and right sides of the advertising light box body 7 tightly. By rotating the knob 8 on the first vertical frame 2, the two fixing plates 12 inside it can be driven to approach each other, thereby driving the first horizontal frame 1 and the second horizontal frame 3 to approach each other to fix the top and bottom of the advertising light box body 7 tightly. In addition, the four corners of the advertising light box body 7 can be clamped and fixed by the multiple clamping plates 6 on the first horizontal frame 1 and the second horizontal frame 3, thereby improving the firmness of the installation of the advertising light box body 7, and the installation and disassembly process of the advertising light box body 7 are relatively convenient, thereby improving the practicality of the device.
