A kind of explosion-proof screw and the processing technology of this explosion-proof screw

Abstract

The invention provides an explosion-proof screw. The explosion-proof screw comprises a screw body and an explosion-proof washer, wherein the screw body comprises a rod part and a head part which is positioned at the upper end of the rod part; the explosion-proof washer is cased in a position abutted against the head part, and is integrally fixed to the screw body through threads formed after threading on the rod part. The explosion-proof washer is previously cased and is integrally fixed to the screw body, so the trouble that the explosion-proof washer is required to be manually cased when the screw body is screwed into an object is avoided, the production efficiency is greatly improved, the labor cost is reduced, and the explosion-proof screw is suitable for large-scale production of enterprises. The invention also relates to a machining process of the explosion-proof screw.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to an explosion-proof screw and a processing technology of the explosion-proof screw. Background technique [0002] If the screw in the prior art is directly screwed into an object with higher hardness and greater brittleness, such as an enamelled part, the impact force generated by the screw will easily cause the enameled part to break. For this reason, generally, when screwing in the screw, the installer will insert a washer to buffer the impact force generated by the screw, so as to avoid the cracking of the enamel parts. However, it also brings another problem, that is, the installation Personnel need to insert the gasket on the screw separately, which not only increases the work intensity of the installation personnel, but also reduces the production efficiency of the entire product, increases labor costs, and is not conducive to large-scale production of enterprises.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of the prior art, and provide an explosion-proof screw suitable for use on enamel parts or relatively brittle parts, so as to solve the problem that the existing screws need to be pre-inserted with explosion-proof gaskets before use. Low production efficiency, not suitable for mass production
