Blind pulling rivet

Abstract

The invention discloses a blind pulling rivet. The blind pulling rivet comprises a rivet body, wherein the rivet body is combined by a shank and a sleeve tube; the inner side of the rivet body is fixedly connected with the shank; the outside of the top of the shank is uniformly distributed with snap threads; the bottom of the shank is fixedly connected with a cap head; the top of the cap head is fixedly connected with a shank portion; the encircle portion of the shank portion is uniformly distributed with anti-slip threads; the outside of the shank portion is uniformly distributed with lockingthreads; the outside of the locking threads are provided with anti-rotating threads; and the outside of the rivet body is fixedly connected with the sleeve tube. According to the blind pulling rivet,a tube portion of the sleeve tube is arranged at the outside of the shank portion, and the rivet body penetrates through a first connecting plate and a second connecting plate, so that fixed connection between the first connecting plate and the second connecting plate is achieved; and the rivet body is arranged at the connection point of the first connecting plate and the second connecting body,so that the connection between special workpieces such as blind hole workpieces and connectors with insufficient single edge space is achieved, and the problems of single function and low practicalityof an existing connecting mechanism are solved.

Description

technical field [0001] The invention belongs to the technical field of workpiece fixing accessories, and in particular relates to a blind rivet. Background technique [0002] Existing connection techniques include bolts, welding, stamping riveting, butt-through riveting, etc. The technical solutions are briefly described as follows: (1) Bolt connection: first insert the bolt into the mounting hole, and fix the head of the bolt to prevent it from rotating, and then insert the nut Screw on the bolt and continue to rotate and tighten to achieve the connection effect between the workpieces; (2) Welding connection: firstly, the workpieces to be connected are closely and orderly fitted together, and then the joint surface, line or point of the workpiece is carried out. Welding operation to achieve the connection effect between the workpieces; (3) Stamping riveting connection: first insert the rivet into the mounting hole, and place or fix the rivet head on the fixed end of the riv...
