Anti-loosening thread fastening components and threaded fastener locking rings

Abstract

The invention relates to a locking thread fastening module and a thread fastening piece locking ring. The locking thread fastening module comprises a thread fastening piece and a locking ring; a convex-concave rotating stop structure is arranged on the outer wall of the thread fastening piece; the locking ring comprises a main body, and a rotating stop projection exceeding the inner wall of the main body and used for cooperating with a recess part of the convex-concave rotating stop structure; embedding teeth for embedding in a connecting piece for rotating stop cooperation with the connectingpiece is arranged on the outer wall of the main body; at least one of the rotating stop projection and the recess part is provided with an inclined guide surface for rotating out the rotating stop projection from the recess part when the two are relatively rotated; the main body achieves radial elastic deformation performance; and through the radial elastic deformation performance, when a torqueis applied to the thread fastening piece, the rotating stop projection can move to the radial outer side of the main body under the effect of the inclined guide surface to rotate out from the corresponding recess part of the convex-concave rotating stop structure, so that the rotation of the thread fastening piece in the main body is realized. The locking thread fastening module is simple and convenient to use.

Description

Technical field [0001] The present invention relates to a fastening assembly and a locking screw threaded fastener locking ring. Background technique [0002] Most of the engine case structure is connected Space studs are used, both ends of the studs respectively have a threaded, wherein the threaded end is threaded for interference and receiver connected by an interference screw through a threaded hole larger than the size of the casing the size of the generated locking force, in order to connect the casing. However, in the use of the engine will generate high frequency vibrations, the studs easy to loose under vibration environment. [0003] Authorized announcement No. CN204041687U, is authorized announcement 2014.12.24 Chinese utility model patent discloses a toothed locking studs, the studs lock the toothed connecting rod comprising a screw and a screw connection, the connecting rod is provided with external spline teeth (i.e. embossed rotation stopping structure), which lock...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a threaded fastener locking ring to solve the problem that the locking ring in the prior art has no elasticity, and the screw pile and the locking ring cannot rotate relative to each other, and can only be knocked into the connecting piece by a special tool. The problem of complicated procedures and inconvenient use; the present invention also provides an anti-loosening threaded fastening assembly using the threaded fastener locking ring
