Embodiment 1

[0019] Such as figure 1 As shown, a mechanical part connector includes a screw and a nut, the nut includes a nut body 4, the bolt includes a screw section and a nut end 1 arranged at the end of the screw section, and the nut end A plurality of elastic protrusions 3 are provided on the end surface close to the screw section and the end surface of the nut body 4 close to the nut end 1, and the elastic protrusions 3 can be elastically deformed during the tightening process of the bolt.

[0020] In this structure, the set screw section 2 has threads, which are used for threaded connection with the nut in the bolt connection to fasten the interconnected connectors. The above nut end 1 is used as the driving force for the operator to brake the rotation of the screw section 2. part. In this structure, by setting the elastic protrusion 3 on the end surface of the nut end 1 close to the end of the screw section 2, in this way, during the tightening process of the bolt, the elastic pro...

Embodiment 2

[0023] Such as figure 1 As shown, this embodiment is further limited on the basis of Embodiment 1: In order to make the above prestress evenly distributed in the circumferential direction of the bolt, the elastic protrusions 3 on both end faces are annular with respect to the axis of the screw segment 2 Evenly distributed.

[0024] As a further technical solution to make the above prestress evenly distributed in the circumferential direction of the bolt, the number of elastic protrusions 3 on both end faces is greater than three.

[0025] As a connector form that is convenient for processing and manufacturing, the elastic protrusion 3 on the nut end 1, the screw section and the nut end 1 is an integral structure formed by casting; the nut body 4 and the nut body The elastic protrusion 3 on the 4 is an integral structure formed by casting.

Abstract

The invention discloses a mechanical part connector, 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, and the nut end is close to the A plurality of elastic protrusions are provided on the end surface of the screw rod section and the end surface of the nut body near the nut end, and the elastic protrusions can produce elastic deformation during the tightening process of the bolt. The connecting piece provided by the present invention also has good anti-loosening ability even if the elastic pad is not matched with it.

Description

technical field [0001] The invention relates to the technical field of mechanical connectors, in particular to a mechanical part connector. 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 relatively common form is the use of elastic wash...
