It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Please see Figures 1-4 This utility model provides a technical solution: a novel combined top plate chain, comprising: several top plates 1 and rotating plates 9. Each top plate 1 is square tube shaped. Fixed posts 5 are fixedly installed on the left and right sides of the lower inner wall of each top plate 1. Limiting posts 7 are symmetrically and elastically connected to the front and rear ends of each fixed post 5. Circular grooves 6 are opened on the front and rear sides of the upper end of each fixed post 5. A limiting post 7 is slidably inserted into each circular groove 6. A spring 8 is fixedly installed on the inner end of the limiting post 7. The inner end of the spring 8 is fixedly connected to the inner wall of the inner end of the circular groove 6. When the spring 8 is in a balanced state, the outer end of the limiting post 7 is located outside the circular groove 6, and the inner end is located inside the circular groove 6. The limiting post 7 can be moved within the circular groove 6 by compressing the spring 8.
[0022] Rotating cylinders 10 are fixedly installed on the upper ends of the left and right sides of each rotating plate 9. The rotating cylinders 10 pass through the upper and lower ends of the rotating plate 9. Limiting rings 11 are fixedly installed on the upper ends of the rotating cylinders 10. The inner diameters of the limiting rings 11 and the rotating cylinders 10 are slightly larger than the diameter of the fixed column 5. The rotating cylinders 10 at the left and right ends of the rotating plate 9 are respectively inserted into the two top plates 1 and rotated and sleeved on the outside of the fixed column 5. When the rotating cylinders 10 are sleeved on the outside of the fixed column 5, the limiting rings 11 are located at the lower end of the limiting column 7. The limiting rings 11 limit the limiting column 7 to prevent the limiting rings 11 and the rotating cylinders 10 from falling off the fixed column 5, connecting the two adjacent top plates 1 together and rotating through the rotating plate 9.
[0023] An elastic connecting plate 12 is fixedly installed between two adjacent top plates 1. The elastic connecting plate 12 is U-shaped, and plug-in plates 13 are fixedly installed at both ends of the elastic connecting plate 12. The plug-in plates 13 and the elastic connecting plates 12 are made of elastic steel sheets, which have good elasticity and stability, and cover the gap between the two adjacent top plates 1. They also rotate with the top plate 1 through elastic deformation. Fixing holes 14 are opened on the side walls of the front and rear ends of the two plug-in plates 13.
[0024] The plug-in plate 13 can be inserted into the inner end of the top plate 1, and the upper end of the elastic connecting plate 12 is flush with the upper end and the upper end of the top plate 1, respectively. Threaded posts 2 are fixedly installed on the inner walls of the front and rear sides of the left and right ends of the top plate 1. When the plug-in plate 13 is inserted into the top plate 1, the two side walls of the plug-in plate 13 are pushed inward so that the fixing hole 14 is sleeved on the outer end of the threaded post 2. Then, a washer 4 is sleeved on the outer end of the threaded post 2 and a fastening nut 3 is threadedly connected, thereby fixing the plug-in plate 13 to the inner end of the top plate 1 and fixing the elastic connecting plate 12 between two adjacent top plates 1.
[0025] In actual use, several top plates 1 are spliced together by rotating plate 9 to form a top plate chain. The rotating cylinders 10 at the left and right ends of rotating plate 9 are inserted into two top plates 1 respectively and rotated and sleeved on the outside of fixed column 5. Then, insert plate 13 is inserted into top plate 1. By pushing the two side walls of insert plate 13 inward, the fixing hole 14 is sleeved on the outer end of threaded column 2. Then, a washer 4 is sleeved on the outer end of threaded column 2 and a fastening nut 3 is threadedly connected, thereby fixing insert plate 13 to the inner end of top plate 1. The elastic connecting plate 12 is fixed between two adjacent top plates 1 to cover the gap between two adjacent top plates 1. And through elastic deformation, it rotates with top plate 1 to prevent small objects from getting stuck in the gap between two adjacent top plates 1 when transporting them.
