Detailed Description

The following description of the embodiments of the present utility model will be made more clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model provides a novel waterproof P+R key, which comprises a silica gel sheet 1 and a plastic sheet 2, wherein the plastic sheet 2 is buckled above the silica gel sheet 1, an installation part 11 is arranged in the middle of the silica gel sheet 1, an outer convex part 21 is arranged at the lower part of the plastic sheet 2, the outer convex part 21 is arranged in the installation part 11, the upper part of the section of the outer convex part 21 is of a square structure, and the lower part of the section of the outer convex part is of a polygonal structure.

The waterproof P+R key mainly comprises a silica gel sheet 1 and a plastic sheet 2 buckled on the silica gel sheet 1, wherein the middle part of the silica gel sheet 1 is provided with an installation part 11, the lower part of the plastic sheet 2 is provided with an outer convex part 21, and the outer convex part 21 is installed in the installation part 11, so that the silica gel sheet 1 and the plastic sheet 2 are directly fixed in a buckling manner, the key is convenient and quick to assemble, and the labor cost is further saved; through setting the upper portion of outer convex part 21 cross-section to square structure, the lower part sets up to polygonal structure, prevents to drop in the installation department 11 after outer convex part 21 installation is fixed, guarantees that cosmetic product's installation stability is good.
