DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 5 As shown in the figure, a chain plate clamping structure includes a main chain plate 1 and a sub-chain plate 2 which are hinged. On one outer wall of the main chain plate 1, an extension groove 3 is provided. A slidable concave connecting plate 4 is arranged in the extension groove 3. A pushing component 5 for pushing the concave connecting plate 4 to move is arranged in the extension groove 3. On one side of the sub-chain plate 2, a hinge plate 6 is provided.

[0022] As Figure 4 shown, sliding T-shaped grooves are provided on the inner walls at both ends of the extension groove 3. T-shaped sliding blocks 7 are arranged at the outer wall corner positions at both ends of the concave connecting plate 4. The T-shaped sliding blocks 7 and the sliding T-shaped grooves are slidably clamped with each other. Clamping grooves 12 are symmetrically and evenly provided on the top surface of the concave connecting plate 4. The pushing component 5 includes a rotating screw 501. One end of the rotating screw 501 is rotatably installed on the inner wall at one end of the extension groove 3. The other end of the rotating screw 501 penetrates through the inner wall at the other end of the extension groove 3 and extends to the outer wall at one end of the main chain plate 1. A circular groove is provided on the outer wall at one end of the main chain plate 1. One end of the rotating screw 501 is located in the circular groove. Pushing gears 502 are symmetrically sleeved on the circumferential surface of the rotating screw 501. The pushing gears 502 and the clamping grooves 12 are meshed with each other. Tightening threaded holes 8 are evenly arranged at the middle position on the upper surface of the concave connecting plate 4. One end of the tightening threaded holes 8 penetrates through the upper surface of the concave connecting plate 4 and extends to the inner bottom wall of the extension groove 3, so as to drive the pushing gears 502 to rotate by twisting the rotating screw 501, and then push the concave connecting plate 4 to move horizontally through the meshing between the pushing gears 502 and the clamping grooves 12. At the same time, through the limitation between the T-shaped sliding blocks 7 and the sliding T-shaped grooves provided, it can be ensured that the concave connecting plate 4 moves stably.

[0023] As Figure 2 and Figure 3As shown, a circular convex groove 9 is provided on the upper surface of the main chain plate 1. A fastening screw rod 10 is meshed in the circular convex groove 9. One end of the fastening screw rod 10 is meshed with the fastening threaded hole 8, and the top surface of the fastening screw rod 10 is meshed with the top surface of the main chain plate 1. Hinge threaded holes are provided at both ends of one side of the concave connecting plate 4. A pin hole is provided at one end of the hinge plate 6. The axes of the hinge threaded hole and the pin hole are collinear. A hinge threaded rod 11 is inserted into the hinge threaded hole and the pin hole together, so as to facilitate the fastening connection between the fastening screw rod 10 and the fastening threaded hole 8 after the concave connecting plate 4 moves, and further prevent the concave connecting plate 4 from falling off the extension groove 3 when transporting goods on the upper surfaces of the main chain plate 1 and the sub-chain plate 2.

[0024] When the present utility model is in use, the staff splices multiple main chain plates 1, and then when the staff finally splices the main chain plate 1 and the sub-chain plate 2, the staff splices the main chain plate 1 with the sub-chain plate 2 through the concave connecting plate 4 provided in the main chain plate 1. When the staff finds that the concave connecting plate 4 on the main chain plate 1 and the hinge plate 6 on the sub-chain plate 2 cannot be accurately docked, at this time, the staff can twist the rotating screw rod 501 with a tool. At this time, the rotation of the rotating screw rod 501 drives the pushing gear 502 to rotate. The rotation of the pushing gear 502 drives the concave connecting plate 4 to rotate. Then, under the limitation of the T-shaped sliding block 7 and the sliding T-shaped groove, the concave connecting plate 4 can stably move in the extension groove 3. At this time, when the concave connecting plate 4 and the hinge plate 6 are docked, the staff makes the concave connecting plate 4 and the hinge plate 6 dock through the hinge threaded rod 11. At the same time, when the main chain plate 1 and the sub-chain plate 2 are connected into a ring shape, when the staff needs to disassemble the main chain plate 1 and the sub-chain plate 2, at this time, the staff can adjust the position of the concave connecting plate 4 in the extension groove 3, adjust the space size between the main chain plate 1 and the sub-chain plate 2, and then adjust the tightness between the main chain plate 1 and the sub-chain plate 2, thereby improving the use effect of the present device.
