Mechanical part connecting piece capable of being independent of elastic washer

Abstract

The invention discloses a mechanical part connector which does not rely on an elastic washer, which includes a screw and a nut, the nut includes a nut body, the bolt includes a screw section and a nut end arranged at the end of the screw section, A plurality of elastic protrusions are arranged on the end face of the nut end close to the screw section and the end face of the nut body close to the nut end, and the elastic protrusions can produce elastic deformation during the tightening of the bolt; A setting in which the free end is inclined in the direction of loose connection of mechanical parts. The connecting piece provided by the present invention also has a good anti-loosening ability even when the elastic pad is not used in conjunction with it; the free end of the elastic protrusion is set to be inclined in the direction of loosening the connecting piece of the mechanical part, so that the mechanical parts can be connected In the process of tightening the parts, the deformation of the elastic protrusions is guided, so that the elastic protrusions are easy to be forced to deform elastically, and the technical effect of facilitating the tightening of the connecting parts of the mechanical parts is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical connectors, in particular to a mechanical component connector which does not rely on elastic washers. Background technique [0002] A bolt is a mechanical part, usually a cylindrical threaded fastener with a nut. The bolt is composed of two parts, the head and the screw rod (a cylinder with external threads). When used, it needs to cooperate with the nut to fasten and connect two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. According to the way of connection force: divided into ordinary and hinged holes. According to the shape of the head: there are hexagonal head, round head, square head, countersunk head, etc. Among them, the hexagonal head is the most commonly used. [0003] At present, for the anti-loosening of bolted connections, a relat...
