Abstract

The invention relates to the technical field of fastener self-locking, in particular to a locking bolt with an elastic quick release mechanism. The locking bolt comprises a top bolt head and an arc-shaped externally threaded assembly plate. According to the locking bolt with the elastic quick release mechanism, the split type structural design is adopted, a strip-shaped inserting groove used for installing the arc-shaped externally threaded assembly plate is formed in the outer side face of an assembly shaft tube, people can quickly change the specification and size of the bolt by replacing the arc-shaped externally threaded assembly plate according to needs, and the application range of the locking bolt is wider; the arc-shaped externally threaded assembly plate is quickly assembled together with the assembly shaft tube in the manner that an assembly strip is inserted into the strip-shaped inserting groove, a top limiting disc at the top end of an elastic internal telescopic rod is used for extruding and limiting the assembly strip, the assembly and disassembly operation is easy and quick, assembly and disassembly are convenient, and the use cost of a later period is reduced; and meanwhile, the inner side of a screw hole is elastically squeezed, so that the anti-loosening performance of the whole bolt is improved, and the safety of the bolt is improved.

Description

Technical field

[0001] The present invention relates to a technical field self-locking fastener, in particular a resilient locking bolt having a quick-release mechanism. Background technique

[0002] Mechanical parts bolt is equipped with a cylindrical nut with a threaded fastener. And a screw head (cylinder with external thread) for a class of two-part fasteners, to be fitted with the nut, for fastening the two parts having through holes. This connection form is also referred bolted. Applications bolts are: electronic products, machinery products, digital products, electrical equipment, machinery and electrical machinery products. Ships, vehicles, hydraulic engineering, and even chemistry experiment is also useful to bolt, is widely used.

[0003] Most of the current market, the bolt a simple structure, requires mating externally threaded rod and bolt head assembly in fixed limit, the main assembly is fixed by a frictional force to the screw head and the threaded surfaces betwee...
