Novel rust-proof screw

Abstract

A novel rust-proof screw comprises a screw main body. The screw main body is composed of a conventional screw head and a threaded rod. An oil injection hole is formed in the center of the screw head. An oil storage tank perpendicular to the ground is longitudinally arranged at the center of the threaded rod. The oil injection hole communicates with the oil storage tank. The oil storage tank is further horizontally and perpendicularly provided with an oil guide channel with the oil storage tank perpendicular to the ground as the benchmark. The oil guide channel radiallly outwards radiates and penetrates through the threaded rod and communicates with the outside. The oil injection hole is of a T-shaped structure, and a T-shaped rubber plug matched with the oil injection hole is arranged.

Description

technical field [0001] The invention belongs to the field of mechanical tooling and relates to a screw, in particular to a novel anti-rust screw. [0002] technical background [0003] In the prior art, when the screw is screwed into the workpiece, anti-rust agent will be dripped on the edge of the screw to prevent rust in the later stage, but this traditional anti-rust agent dripping method often produces anti-rust agent during the dripping process It is difficult to penetrate, or the problem that the anti-rust oil cannot penetrate due to the close contact between the screw thread and the thread groove. In terms of material saving, traditional screw rust prevention often results in a large amount of waste of rust inhibitors, and cannot achieve better screw rust prevention. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new type of anti-rust screw with good anti-rust effect, convenient ...
