Height limiting rivet

Abstract

The invention discloses a height limiting rivet. The height limiting rivet comprises a rivet body and a rivet core, wherein a rivet body head is arranged at the top end of the rivet body, an inclinedplane is arranged at the bottom of the rivet body, a rivet body rod is arranged outside the rivet body, a convex body is arranged above the inner wall of a rivet body hole, and a groove is formed in the upper portion of the outer wall of the rivet body rod; and a breakage rod is arranged at the top of a breakage groove, an oblique angle piece is fixedly installed at the top of the breakage rod, arivet core rod is arranged at the bottom of the rivet core, a connection mode between the rivet body and the rivet core is simple, a riveting process can be achieved without too complex operation tools, the riveting process is simpler and more convenient, the labor burden of workers is reduced, the blind rivet head is low after the rivet body and the rivet core are riveted, and the situation thatthe height of the rivet is so high as to influence subsequent use is avoided, so that the rivet has better convenience and is more convenient for people to use.

Description

technical field [0001] The invention belongs to the technical field of riveting, in particular to a height-limiting rivet. Background technique [0002] Blind rivets are a kind of rivets that are riveted on one side. Because single-sided riveting is relatively simple and convenient, blind rivets can be rapidly developed and applied to all walks of life, so they are widely used in construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products. Blind rivets are divided into open type, closed type, structural type, etc. Among them, the open type and closed type are formulated by ISO and GB / T standards in the world and my country respectively; the structural type rivets are formulated by several large companies in the world. The standard only clearly stipulates various dimensions and performance standards, and does not specify the height of the blind rivet head after riveting. [0003] Open-type riveting needs to be realized by extendi...

AI Technical Summary

Problems solved by technology

[0003] Open-type riveting needs to be realized by extending the nail body to wrap the mandrel head, so the nail body must be long enough, and the height of the blind rivet head after riveting is also relatively high; there is a large part of the length above the closed mandrel head The pre-reserved nail body has a relatively high height of the blind rivet head after riveting; the structural type of the nail mandrel is exposed outside after riveting, and the height of the blind rivet head after riveting naturally cannot be lowered; In the case of high, the current blind rivets cannot be used
