However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1 - 4As shown in the figure, the utility model provides a plastic drainage board assembly, including a drainage board body 1. Connection grooves 3 are provided on the outer four sides of the drainage board body 1. Connection ports 4 are penetrated and provided on the inner walls of the four connection grooves 3. One end of the drainage board body 1 is provided with a connection plate 6. Plug plates 8 are fixedly installed at both ends of the outer part of the connection plate 6. A limiting groove 9 is provided inside the connection plate 6. A plurality of uniformly distributed springs 10 are fixedly installed on the inner wall of the limiting groove 9. A moving plate 11 is fixedly installed at the top of the plurality of springs 10. Second openings 15 are penetrated and provided on both sides inside the limiting groove 9. Storage grooves 13 are provided at the tops of the two plug plates 8. First openings 12 are penetrated and provided on the opposite sides of the two storage grooves 13. Two clamping blocks 14 are fixedly installed at the top of the moving plate 11. The two clamping blocks 14 are respectively slidably connected with the two storage grooves 13. A fixing groove 16 is provided at the top of the connection plate 6. A connecting rod 18 is fixedly installed at the top of the moving plate 11. The top of the connecting rod 18 penetrates the limiting groove 9 and enters the fixing groove 16 and is fixedly installed with a pulling plate 19.

[0024] The effect achieved by the entire embodiment 1 is that during connection, the staff presses the pulling plate 19. The pulling plate 19 drives the moving plate 11 to descend through the connecting rod 18, thereby driving the two clamping blocks 14 to enter the two storage grooves 13 respectively, and the springs 10 are compressed. Then the staff inserts the plug plates 8 into the connection grooves 3. When the clamping blocks 14 move below the connection ports 4, the staff releases the pulling plate 19. The elastic force of the springs 10 pushes the two clamping blocks 14 to enter the connection ports 4 on the two drainage board bodies 1 respectively. At this time, the two drainage board bodies 1 are connected together. During disassembly, the staff presses the pulling plate 19, and the clamping blocks 14 leave the connection ports 4. At this time, the plug plates 8 can be pulled out, and the disassembly can be completed at this time, which facilitates the replacement of the drainage board body 1.

[0025] Embodiment 2, as Figures 1 - 4 shown, further, internal threads 22 are provided on the inner wall of the fixing groove 16, and a protective groove 17 is provided on the inner wall of the fixing groove 16.

[0026] Further, a protective plate 20 is slidably installed inside the protective groove 17. A threaded rod 23 is fixedly installed at the bottom of the protective plate 20. The threaded rod 23 is threadedly connected with the internal threads 22. A handle 21 is fixedly installed at the top of the protective plate 20.

[0027] Further, a plurality of uniformly distributed top platforms 2 are fixedly installed at the top of the drainage board body 1, and a plurality of uniformly distributed through grooves 7 are provided at the bottom of the drainage board body 1.

[0028] Further, a plurality of uniformly distributed diversion grooves 5 are provided at the top of the drainage board body 1. When the plastic drainage board is bent or wound and taken and placed, the diversion grooves 5 can provide a buffer space for the inner wall extrusion of the drainage board, avoid excessive extrusion of the drainage board, and extend the service life.

[0029] Further, the outer walls of the two clamping blocks 14 are respectively in contact with the inner walls of the two storage grooves 13, the outer wall of the clamping block 14 is in contact with the inner wall of the connection port 4, and the outer wall of the insertion plate 8 is in contact with the inner wall of the connection groove 3, preventing the clamping block 14 from shaking when the clamping block 14 enters the connection port 4.

[0030] Further, the outer wall of the protection plate 20 is in contact with the inner wall of the protection groove 17, preventing external objects and moisture from entering the fixing groove 16 and affecting the pull plate 19.

[0031] The effect achieved by the entire Embodiment 2 is that after the two drainage plate bodies 1 are connected together, the staff inserts the threaded rod 23 into the internal thread 22 and rotates the handle 21. The threaded rod 23 rotates, causing the threaded rod 23 to move downward along the internal thread 22 until the bottom of the protection plate 20 is in contact with the inner wall of the protection groove 17. At this time, the outer wall of the protection plate 20 is in contact with the inner wall of the protection groove 17, thus ensuring that foreign objects are prevented from entering the fixing groove 16 and causing accidental contact with the pull plate 19.

[0032] Working principle: During connection, the staff presses the pull plate 19. The pull plate 19 drives the moving plate 11 to descend through the connecting rod 18, thereby driving the two clamping blocks 14 to enter the two storage grooves 13 respectively, and the spring 10 is compressed. Then the staff inserts the insertion plate 8 into the connection groove 3. When the clamping block 14 moves below the connection port 4, the staff releases the pull plate 19, and the elastic force of the spring 10 pushes the two clamping blocks 14 to enter the connection ports 4 on the two drainage plate bodies 1 respectively. At this time, the two drainage plate bodies 1 are connected together. During disassembly, the staff presses the pull plate 19, and the clamping block 14 leaves the connection port 4. At this time, the insertion plate 8 can be withdrawn, and the disassembly is completed, facilitating the replacement of the drainage plate body 1. After the two drainage plate bodies 1 are connected together, the staff inserts the threaded rod 23 into the internal thread 22 and rotates the handle 21. The threaded rod 23 rotates, causing the threaded rod 23 to move downward along the internal thread 22 until the bottom of the protection plate 20 is in contact with the inner wall of the protection groove 17. At this time, the outer wall of the protection plate 20 is in contact with the inner wall of the protection groove 17, thus ensuring that foreign objects are prevented from entering the fixing groove 16 and causing accidental contact with the pull plate 19.

[0033] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical content of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
