Abstract

The invention provides a rivet nut, and particularly relates to the technical field of riveting fasteners. The rivet nut comprises a stop portion, a tubular portion, an elastic deformation portion and a threaded connecting body, wherein the stop portion is connected with one end of the tubular portion and stops at one side of a rivet nut mounting hole; the elastic deformation portion is connected with the other end of the tubular portion and is provided with a deformation body and a containing cavity; the deformation body penetrates through the rivet nut mounting hole after being axially stretched and deformed, and stops at the other side of the rivet nut after being axially compressed and deformed; and the threaded connecting body is arranged in the containing cavity and is connected with the end, facing away from the tubular portion, of the elastic deformation portion. According to the rivet nut, a rivet tool does not need to be independently arranged, and deformation of the elastic deformation portion can be realized by means of a screw; and the deformation of the elastic deformation portion of the rivet nut is elastic deformation, so that the rivet nut is convenient to disassemble or replace.

Description

technical field [0001] The invention relates to the technical field of riveted fasteners, in particular to a blind rivet nut. Background technique [0002] Traditional automotive exterior parts (external parts) are externally connected to counterparts, usually using self-tapping screws or blind rivet nuts. The self-tapping screw connection is easy to loosen during the long-term vibration of the car, and the blind rivet nut has become an important means of nut connection for the car body because of its low cost, high connection efficiency and simple method. [0003] At present, the common blind rivet nut is in the state of penetrating the hole of the installed part, and the tubular part is buckled by using a blind riveting tool to expand the diameter of the tubular part, and it is clamped between the buckled tubular part and the flange. Installed parts, and then install other installed parts through matching screws / bolts. Because the blind rivet nut must be used with the bl...
