Description

Novel quick-mounting rivet

Technical Field

The invention relates to the field of rivets, in particular to a novel quick mounting rivet.

Background

Rivets are nail-shaped articles used to connect two parts or components with through holes and a cap at one end. In riveting, the riveted parts are connected by self-deformation or interference. When traditional rivet is installed, pass the preset hole of mounting with rivet cover and rivet round pin post now, then follow the top of rivet round pin post, utilize the riveter to carry and draw, the inflation portion of rivet round pin post bottom rises in the rivet cover for the inflation of rivet cover bottom, then the rivet round pin post rises to certain distance after, receives the pulling force of limit and breaks from the centre, rivet round pin post and rivet cover can be fixed on the mounting. The rivet guns are divided into pneumatic rivet guns, electric rivet guns, manual rivet guns and hydraulic rivet guns according to different power, however, in some cases, for example, when no rivet gun is used for installing a rivet, the rivet is installed slowly, a rivet pin cannot bear extreme pulling force, the difficulty of lifting the rivet pin is high, and after the rivet pin is broken, a cavity is formed in the rivet sleeve, so that the fixing strength of the rivet sleeve is reduced; and the traditional rivet is difficult to disassemble after being installed and is inconvenient to fix during inspection and maintenance.

To address the problems in the related art, we propose a new type of quick setting rivet.
