Anti-falling safety pressure pressing rivet nut

Abstract

The invention relates to the technical field of nuts, and discloses an anti-falling safety pressing rivet nut. The anti-falling safety pressing rivet nut comprises a supporting plate, a rollover riveting ring, a nut block, a supporting outer plate, a reset spring, a rotating block and a rotating plate, wherein the supporting plate comprises a supporting plate shell, flange riveting claws and sunkcave deformed material accumulating grooves, wherein the lower surface of the rollover riveting ring is fixedly connected with the upper surface of the supporting plate shell, the lower surfaces of the flange riveting claws are fixedly connected with the upper surface of the supporting plate shell, a riveting claw grooves are formed in the upper surfaces of the flange riveting claws, the upper surface of the nut block is fixedly connected with the lower surface of the supporting plate, two limiting holes are formed in the lower surface of supporting outer plate shell, the supporting outer plate comprises a rotating groove, the limiting holes and the supporting outer plate shell, the nut block is positioned in the supporting outer plate shell, a rotating groove is formed in the upper surface of a rotating plate shell, the rotating block is inserted into the rotating groove, and the rotating block is movably connected with a rotating plate. The pressing rivet nut has the advantages thatthe after the pressing rivet nut is pressed and riveted on a dissimilar material, a thin sheet metal and a high-strength steel sheet, a bolt can be stably fixed on the sheet metal.

Description

technical field [0001] The invention relates to the technical field of nuts, in particular to an anti-falling safety rivet nut. Background technique [0002] Rivet nuts are also called rivet nuts, self-fastening nuts, which are used for riveting fasteners, standard parts, and rivet nuts are generally used in automotive body metal sheet metal industry products, metal stamping or copper, aluminum and plastic materials. When installing, it is necessary to put the end of the rivet nut with the tooth surface into the product material matrix by stamping or other means of extrusion. It is a kind of nut applied to thin plates or sheet metals. It is round in shape and embossed at one end. teeth and guide slots. 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 ...
