Self-plugging rivet with anti-loosening structure

Abstract

The invention relates to the field of rivets, in particular to a self-plugging rivet with an anti-loosening structure. The self-plugging rivet comprises a riveting body and a nail body, the riveting body is arranged on the nail body in a sleeving mode, one end of the nail body is connected with a limiting cap connected with the end portion of the riveting body, the end, away from the limiting cap, of the riveting body is provided with a nail cap, the inner wall of the riveting body is provided with a plurality of limiting grooves, and the upper portion of one end of the inner wall of each limiting groove is rotatably connected with a protruding plate matched with the limiting groove. A first spring is fixedly arranged in each limiting groove, the other ends of the first springs are fixedly connected with the protruding plates, the ends, away from the hinge points, of the protruding plates are arranged towards one side of the nail cap, and limiting blocks matched with the protruding plates are arranged on the nail body. The self-plugging rivet is not easy to loosen after being riveted, and the riveting quality is improved.

Description

technical field [0001] The invention relates to the field of rivets, in particular to a blind rivet with an anti-loosening structure. Background technique [0002] Blind rivets are a kind of rivets used for single-sided riveting, but they must be riveted with a special tool—a riveting gun (manual, electric, pneumatic). When riveting, the rivet core is pulled by a special riveting gun to expand the riveting body and play a riveting role. This type of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets (riveting must be done from both sides), so it is widely used in construction, automobiles , Ships, aircraft, machines, electrical appliances, furniture and other products. Among them, the open type oblate head blind rivets are the most widely used, the countersunk head blind rivets are suitable for riveting occasions where the surface needs to be smooth, and the closed blind rivets are suitable for riveting occasions requiring hi...

AI Technical Summary

Problems solved by technology

[0003] However, the existing blind rivets have the following defects: after the existing part of the blind rivets are riveted, due to the influence of the storage environment, the riveted parts will vibrate, which leads to the loosening of the blind rivets, which ultimately affects quality of riveting
