[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 4 In an embodiment of the utility model, a plastic drain board that is easy to install includes a plastic drain board 1 composed of a base plate 101 and a hollow protrusion 102. The hollow protrusion 102 is integrally formed at the top of the base plate 101. A vertical stopper assembly is provided at the top of the hollow protrusion 102 and the top of the inner wall. An edge stopper assembly is provided at the bottom of the outer wall of the hollow protrusion 102 and the edge of the base plate 101.

[0027] The two hollow protrusions 102 that are sleeved up and down are limited in the vertical direction by a vertical limiting assembly;

[0028] The edge of the substrate 101 is limited by an edge limiting component between two substrates 101 laid in the horizontal direction;

[0029] The vertical limit assembly cooperates with the edge limit assembly to prevent the joint of the two sections of the plastic drainage board 1 from warping;

[0030] The edge limiting assembly includes a docking hole slot 2, a convex card slot 3, a docking column 4, and a convex card block 5;

[0031] The docking hole groove 2 and the convex card groove 3 are integrally formed at the top of the hollow protrusion 102. The docking hole groove 2 is located at the top center of the hollow protrusion 102. A plurality of convex card grooves 3 are provided. The plurality of convex card grooves 3 are distributed in a ring shape around the center of the docking hole groove 2 on the outside of the docking hole groove 2 and penetrate the outside of the hollow protrusion 102.

[0032] The docking column 4 and the convex block 5 are integrally formed at the top of the inner wall of the hollow protrusion 102. The docking column 4 is located at the center of the top of the inner wall of the hollow protrusion 102. A plurality of convex blocks 5 are provided, and the plurality of convex blocks 5 are annularly distributed on the outer side of the docking column 4.

[0033] The two hollow protrusions 102 are sleeved up and down to achieve vertical positioning by engaging the convex clamping block 5 on the upper hollow protrusion 102 with the inner side of the convex clamping groove 3 on the lower hollow protrusion 102;

[0034] The edge limiting assembly includes a limiting ring 6 and an arc-shaped slot 7;

[0035] The limiting ring 6 is integrally formed on the outer side of the hollow protrusion 102 near the bottom, and the arc-shaped slots 7 are integrally formed on the two end edges of the base plate 101;

[0036] When two sections of plastic drain boards 1 are spliced, the upper substrate 101 is clamped to the outer side of the hollow protrusion 102 on the other plastic drain board 1 through the arc-shaped clamping groove 7, and the upper surface of the edge of the substrate 101 is in contact with the lower surface of the limiting ring 6, and the edge of the upper substrate 101 can be limited by the limiting ring 6;

[0037] The inner wall diameter of the arc-shaped slot 7 matches the bottom outer diameter of the hollow protrusion 102 , the height between the limiting ring 6 and the upper surface of the substrate 101 matches the thickness of the substrate 101 , and the outer diameter of the limiting ring 6 is larger than the inner diameter of the arc-shaped slot 7 .

[0038] In this embodiment: it is necessary to supplementally explain that: arc-shaped slots 7 are formed on both ends of the plastic drain board 1 (only the arc-shaped slot 7 structure of one end edge is shown in the figure);

[0039] After one section of the plastic drain board 1 is laid, when another section of the plastic drain board 1 is spliced ​​with the first section of the plastic drain board 1, the hollow protrusion 102 on the second section of the plastic drain board 1 can be sleeved on the top of the hollow protrusion 102 of the first section of the plastic drain board 1. At this time, the docking column 4 and the convex clamping block 5 on the second section of the plastic drain board 1 are respectively clamped on the inner sides of the docking hole groove 2 and the convex clamping groove 3 on the first section of the plastic drain board 1;

[0040] Since the edges of the convex block 5 and the convex slot 3 have a certain elasticity, when the convex block 5 is inserted into the convex slot 3, the edges of the convex block 5 and the convex slot 3 will be deformed, so that the convex block 5 can be smoothly and completely inserted into the convex slot 3, and then the edges of the convex block 5 and the convex slot 3 will be reset under their own elasticity. At this time, the edges of the convex block 5 and the convex slot 3 are mutually attached and connected, thus providing a vertical limiting force for the two sections of the plastic drainage board 1;

[0041] After the hollow protrusions 102 on the two sections of the plastic drain board 1 are sleeved, the edge of the second section of the plastic drain board 1 can be slightly bent and the arc-shaped slot 7 can be clamped on the outer bottom of the hollow protrusion 102 on the first section of the plastic drain board 1. Finally, the edge of the second section of the plastic drain board 1 fits with the upper surface of the limiting ring 6. The limiting ring 6 limits the edge of the second section of the plastic drain board 1, thereby effectively preventing the edge of the second section of the plastic drain board 1 from warping.

[0042] Through the coordination of the above-mentioned multiple parts, the warping phenomenon at the joint of two sections of the plastic drain board 1 can be effectively avoided, so that the paving of the plastic drain board 1 maintains good flatness.

[0043] Please refer to Figures 1 to 4 The plastic drainage board 1, the docking hole groove 2, the convex slot 3, the docking column 4, the convex block 5, and the limit ring 6 are integrally formed through an injection molding process, and the arc slot 7 is formed by punching in the later stage.

[0044] In this embodiment: this structure makes the overall production process of the plastic drainage board 1 simple, with fewer steps, and is easy to promote production.

[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
