Abstract

The invention discloses a waterproof press-riveting nut for hardware. The waterproof press-riveting nut comprises a nut body, a limiting platform, a deformation pressing structure, locating teeth anda first annular sealing ring. The nut body is cylindrical. A threaded cavity is formed in the center of the nut body and is of a structure with the upper end being open and the lower end being closed.The limiting platform is arranged at the upper end of the nut body and is in a disc shape. The pressing structure is arranged at the upper end of the limiting platform. The multiple locating teeth are evenly arranged between the pressing structure and the limiting platform. The locating teeth are arranged around the lower end of the limiting platform at equal distance. The open end of the threaded cavity penetrates through the locating platform and the deformation pressing structure. Three annular sealing rings are arranged on the riveting nut and can cooperate with a sheet metal part, the connecting tightness degree between the riveting nut and the sheet metal part can be improved, the waterproof performance can be improved, and the requirements of some special occasions can be met.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of nuts, in particular to the technical field of rivet nuts. [0003] 【Background technique】 [0004] Rivet nuts are also called pressure rivet nuts, self-fastening nuts, which are a kind of nuts applied to thin plates or sheet metals. They are round in shape, with embossed teeth and guide grooves at one end. The principle is to press the embossing teeth into the preset holes of the sheet metal. Generally speaking, the aperture of the preset holes is slightly smaller than the embossing teeth of the rivet nut. The periphery of the hole is plastically deformed, and the deformation is squeezed into the guide groove, thereby producing a locking effect. However, the connection between the existing rivet nut and the plate is not tight enough, and the waterproof performance is poor. Some special occasions require the rivet nut to have good waterproof performance, which cannot be satisfied by the existing r...
