Abstract

The invention discloses a high-efficiency riveting nut, which comprises a metal sleeve, the side wall of the metal sleeve is provided with deformation grooves distributed in an equidistant manner in a ring, the inner wall of the metal sleeve is provided with internal threads, and the outer wall of the metal sleeve is provided with An expansion sleeve, the top of the expansion sleeve is provided with equidistant circularly distributed arc-shaped expansion blocks, the bottom of the side wall of the metal sleeve is provided with an external thread part, and the outer wall of the external thread part is covered with a rubber sleeve. The outer wall of the rubber sleeve is clamped with a metal ring piece, and the bottom end of the side wall of the external thread part is screwed with a fastening cap. The invention improves working efficiency, and at the same time, combined with the arc-shaped expansion block and the expansion sleeve, it can drive the deformation of the expansion sleeve during the deformation process of the metal sleeve to realize riveting. Combined with the anti-skid groove, a better fixing effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of riveting nuts, in particular to a high-efficiency riveting nut. Background technique [0002] Rivet nuts are also called rivet nuts, self-fastening nuts, which are a kind of nuts applied to thin plates or sheet metals. They are round in shape and have 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. [0003] The existing riveting nuts are inconvenient to disassemble and assemble, and the connection effect is average, so a high-efficiency riveting nut is proposed. Contents of the invention [0004] The object of the present invention is to propose a high-efficiency r...
