[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment: An anti-wear polyurethane plate, as Figures 1 - 5As shown in the figure, it includes a polyurethane core board 1 and a metal plate 2. The metal plate 2 has an inner cavity, and the polyurethane core board 1 is installed in the inner cavity of the metal plate 2. One side of the metal plate 2 is provided with a flange 3, and the other side of the metal plate 2 is provided with a notch 4 adapted to the flange 3. A circular groove 5 is provided at the top of the flange 3. A top groove 6 is provided on the upper surface of the metal plate 2 directly above the notch 4. A plug pin 7 is movably inserted into the inner wall of the top groove 6. The plug pin 7 is adapted to the circular groove 5 on the flange 3, and the plug pin 7 is connected to the metal plate 2 through a push-pull assembly. By installing the polyurethane core board 1 in the inner cavity of the metal plate 2 and utilizing the characteristic of the high hardness of the metal plate 2, the polyurethane core board 1 is protected to a certain extent, so that the polyurethane board has a good anti-wear effect and the service life of the polyurethane board is improved.

[0022] Further, the push-pull assembly includes a square plate 8. The square plate 8 is movably installed inside the top groove 6. The top end of the plug pin 7 is fixedly connected to the lower surface of the square plate 8. The bottom end of the plug pin 7 penetrates through the top groove 6 and extends into the notch 4. A spring 9 is sleeved on the outer surface of the plug pin 7. The two ends of the spring 9 are respectively fixedly connected to the lower surface of the square plate 8 and the inner wall of the top groove 6.

[0023] By setting the spring 9 in a stretched state, due to the elastic recovery of the spring 9, the plug pin 7 and the square plate 8 will tend to move downward; when two metal plates 2 are spliced, the flange 3 on one metal plate 2 is inserted into the notch 4 on the other metal plate 2. At this time, the plug pin 7 on the other metal plate 2 is clamped in the circular groove 5 on the flange 3 of one metal plate 2 under the action of the spring 9, so as to connect and limit the two metal plates 2.

[0024] Further, connecting rods 10 are rotatably connected to both sides of the square plate 8, and a round rod 11 is fixedly connected between the two connecting rods 10.

[0025] After the two metal plates 2 are spliced, the connecting rods 10 and the round rod 11 can be rotated and stored inside the top groove 6. When it is necessary to pull the square plate 8 to split the two metal plates 2, the connecting rods 10 and the round rod 11 can be rotated so that the connecting rods 10 are perpendicular to the square plate 8. Thus, by pulling the round rod 11 upward, the square plate 8 and the plug pin 7 are driven to move upward, and the plug pin 7 is disengaged from the circular groove 5.

[0026] Further, two clamping buckles 12 are fixedly installed on the inner wall of the top groove 6, and the number of the two clamping buckles 12 is two and they are symmetrically arranged.

[0027] When the round rod 11 is stored inside the top groove 6, the round rod 11 can be clamped and limited by the clamping buckles 12 to maintain the stability after the round rod 11 is stored.

[0028] Further, gaskets 13 are fixedly installed on both sides of the metal plate 2, and the upper surface of the gaskets 13 is flush with the upper surface of the metal plate 2.

[0029] The gasket 13 can be made of rubber. When the two metal plates 2 are spliced, the gasket 13 will be squeezed, so as to ensure the sealing performance after the splicing of the metal plates 2.

[0030] Furthermore, the bolt 7 is in a cylindrical structure, and the bottom end of the bolt 7 is inclined inward, that is, the bottom end of the bolt 7 is inclined downward into the notch 4. By adopting the above design, when splicing the two metal plates 2, when the flange 3 of one metal plate 2 is inserted into the notch 4 of the other metal plate 2, the flange 3 of one metal plate 2 will squeeze the bottom end of the bolt 7 of the other metal plate 2, pushing the bolt 7 upward so that the flange 3 of one metal plate 2 can pass through. When the bolt 7 of the other metal plate 2 corresponds to the circular groove 5 of one metal plate 2, under the action of the spring 9, the bolt 7 is clamped in the circular groove 5, thus completing the splicing of the two metal plates 2 and achieving the effect of convenient splicing.

[0031] When splicing two polyurethane plates, the flange 3 of one metal plate 2 can be inserted into the notch 4 of the other metal plate 2. The flange 3 of one metal plate 2 will squeeze the bottom end of the bolt 7 of the other metal plate 2, pushing the bolt 7 upward. When the flange 3 is completely inserted into the notch 4, due to the elastic force of the spring 9, the bolt 7 will move downward, and the bottom of the bolt 7 will be inserted into the circular groove 5, so that the flange 3 can be clamped inside the notch 4, realizing the connection of the two metal plates 2, and the connection is stable and has a high strength. When it is necessary to disassemble the two metal plates 2, only need to pull the round rod 11 upward to drive the square plate 8 upward, so that the bolt 7 moves upward and stretches the spring 9. When the bottom of the bolt 7 disengages from the circular groove 5, the two metal plates 2 can be disassembled, which is simple and convenient.

[0032] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
