Description

Fixed firm pressure rivet nut

[ technical field ] A method for producing a semiconductor device

The utility model relates to a technical field of fastener, especially the technical field of pressure riveting nut.

[ background of the invention ]

The pressure riveting nut is also called a riveting nut, and is a self-fastening nut, which is a fastener for pressure riveting, a standard part, the pressure riveting nut is generally used for products in the metal industry of automobile body metal plates, materials such as hardware stamping or copper-aluminum plastic, and the like. The principle is that the embossing teeth are pressed into the preset hole positions of the metal plate, the aperture of the preset hole is generally slightly smaller than the embossing teeth of the pressure riveting nut, the embossing teeth of the pressure riveting nut are extruded into the plate through pressure to enable the periphery of the hole to generate plastic deformation, and a deformed object is extruded into the guide groove, so that the locking effect is generated, and the pressure riveting nut can be widely applied along with the connection of new energy sources, light weight and heterogeneous materials of an automobile. The existing press riveting nut is not firm enough in fixation.

[ Utility model ] content

The utility model aims at solving the problem in the prior art, providing a fixed firm pressure riveting nut, can make the pressure riveting nut fixed firm.

For realizing the above-mentioned purpose, the utility model provides a fixed firm pressure rivet nut, include nut main part, screw hole, bump, compress tightly dish, spring, the nut main part comprises cylinder, spacing dish, knurling dish, the boss that links to each other in proper order from bottom to top, and the diameter of spacing dish is greater than the diameter of knurling dish, is equipped with a plurality of knurling ponds on the outer wall of knurling dish, the boss is the circular cone frustum shape of invering, and the external diameter of knurling dish is greater than the diameter on boss top, is equipped with a plurality of bumps on the outer wall of boss, be equipped with a lower extreme open-ended screw hole in the nut main part, threaded hole is equipped with one and compresses tightly the dish, and it links to each other through a spring between the roof of the screw hole that compresses.

Preferably, the bumps have gaps therebetween, and the gaps between the bumps can accommodate at least one bump.

Preferably, the salient points are located on the same horizontal circumference, the lower end faces of the salient points are horizontal planes, and the lower projection of the salient points is located in the lower projection of the boss.

Preferably, the side wall of the threaded hole is provided with two guide grooves which are symmetrically distributed, the guide grooves are vertically arranged, the side wall of the pressing disc is provided with a guide block matched with the guide grooves, and the guide block extends into the guide grooves.

The utility model has the advantages that: the utility model has the advantages that the convex points are arranged on the bosses, so that the press riveting nut is firmly fixed and is not easy to loose; the pressing disc is arranged in the threaded hole, and the pressing disc is matched with the spring, so that a thrust can be applied to the bolt when the bolt is screwed on the pressing rivet nut, the bolt is firmly fixed, and the bolt is not easy to loosen.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
