Mechanical self-locking bolt

Abstract

The invention discloses a mechanical self-locking bolt, which comprises a bolt, a nut and a special-shaped spring washer, wherein the special-shaped spring washer sleeves a screw rod of the bolt, and the nut is screwed onto the screw rod; one surface, in contact with the screw rod, of the head of the bolt is provided with a circle of continuously arranged gear structures a, and the upper and lower surfaces of the nut are provided with a circle of continuously arranged gear structures b; the special-shaped spring washer is of a spring-shaped broad-side spring washer structure and has certain thickness, the upper surface of the special-shaped spring washer is provided with a serrated structure c1, and the lower surface of the special-shaped spring washer is provided with a serrated structure c2; the gear structures and the serrated structures are all of right triangle similar and equilateral trapezoid structures, and the two ends of the bottom surfaces of the gear structures and the serrated structures are a forward end and a locking end; the inner angle of the forward end is less than that of the locking end. Because of the excellent locking effect and non-excessively increased cost, the mechanical self-locking bolt provided by the invention has broad market prospects.

Description

technical field [0001] The invention relates to mechanical self-locking bolts. Background technique [0002] There are many types of anti-loosening bolts. The most commonly used ones are spring washers for anti-loosening effect, but the effect is average. There is also an anaerobic adhesive applied to the screw, which works well, but it is not resistant to high temperatures and has a certain shelf life. There is also a method of mechanical destruction to destroy the structure of the bolt body to prevent loosening, but there will be a problem that it is difficult to remove. Contents of the invention [0003] The purpose of the present invention is to provide a mechanical self-locking bolt, which achieves a permanent locking goal through the combined use of special-shaped bolts, nuts and special-shaped spring washers, and can be unlocked and re-locked as required. In order to achieve the above object, the present invention provides the following technical solutions: mechan...
