Embodiment Construction

[0042] The present invention will be further described in detail through the drawings and examples below. Through these descriptions, the features and advantages of the present invention will become more apparent.

[0043] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0044] According to the anti-loosening and anti-disassembly bolt provided by the present invention, the bolt includes a screw rod 1 and a nut 3 matched therewith, and a washer 2 to prevent the nut from loosening is also arranged on the screw rod 1, see figure 1 and figure 2 .

[0045] In a preferred embodiment, the gasket 2 is annular and sleeved on the screw 1, the axis of the...

Abstract

The invention discloses a looseness-preventing and disassembling-preventing bolt. The looseness-preventing and disassembling-preventing bolt comprises a screw, a gasket and a nut, wherein the gasket and the nut are arranged on the screw in a sleeving manner. Grooves extending in the axis direction of the screw are formed in the screw and matched with bosses arranged on the gasket, so that the gasket can only move in the axis direction of the screw and can not rotate around the axis of the screw. The gasket can be in contact with the nut, helical teeth are arranged on the contact faces of the gasket and the nut respectively, and the helical teeth on the gasket are meshed with the helical teeth on the nut, so that when the nut is screwed to the portion where the nut is meshed with the gasket, the nut is locked, looseness caused by vibration and the like can be avoided, and disassembling is also difficult.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to an anti-loosening and anti-disassembly bolt. Background technique [0002] A bolt is a commonly used mechanical part, which is a cylindrical threaded fastener with a nut, specifically a type of fastening consisting of a head and a screw (a cylinder with external threads). It is generally used to fasten and connect two parts with through holes, which have high requirements for fastening performance and fastening strength. [0003] Existing bolts are prone to loosening during use, especially under vibration conditions. After a long period of vibration, the originally locked bolts are easy to loosen. This is mainly due to the characteristics of the bolt itself and the conditions of use. In addition, in some occasions, it is no longer necessary to loosen the bolt after the bolt is tightened and fixed, so it is even more necessary to ensure the anti-loosening performance of the bol...
