Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0013] Such as figure 1 As shown, a kind of mechanical parts connector adopted in the present invention includes a screw and a nut, the nut includes a nut body 4, and the bolt includes a screw section and a nut end 1 arranged at the end of the screw section. The end surface of the nut end 1 close to the screw section and the end surface of the nut body 4 close to the nut end 1 are provided with a plurality of elastic protrusions 3, and the elastic protrusions 3 can produce elastic deformation during the tightening process of the bolt. .

[0014] The elastic protrusio...

Abstract

The invention discloses a mechanical part connecting piece which comprises a screw and a nut. The nut comprises a nut body. A bolt comprises a screw section and a nut end arranged at the end portion of the screw section. Multiple elastic protrusions are arranged on the end face, close to the screw section, of the nut end and the end face, close to the nut end, of the nut body, wherein the protrusions can generate elastic deformation in the bolt screwing process. By means of the mechanical part connecting piece, due to the fact that the elastic protrusions are arranged on the end face of any end of the nut body, the elastic protrusions make contact with a workpiece to generate elastic deformation in the nut screwing process, elastic force generated by the above elastic deformation can serveas prestress of looseness preventing of the nut body, thus, the bolt also has the good looseness preventing capability when an elastic pad is not used in a matched manner.

Description

technical field [0001] The invention relates to a mechanical part, 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 washers. However, in the actua...
