Problems solved by technology

However, during the working process of existing threaded fasteners, due to the influence of device vibration, impact, and working condition changes, there will always be loosening and falling off, resulting in a decrease in fastening force, etc., and even lead to connection failure and falling off, resulting in huge Potential safety hazards and even personal and property damage
[0003] In order to solve this problem, people have invented anti-loosening nuts. The anti-loosening means of existing anti-loosening nuts are roughly divided into two types: the first is to add a nylon apron in the threaded hole of the nut, and use the nylon apron to increase the anti-loosening method. The friction between the threads, but because nylon is prone to aging, it will lose the anti-loosening effect after a long time; the second is to achieve the anti-loosening effect by setting the reverse thread, but the reverse bolt needs to be adjusted according to the needs of the bolt , the cost is high, and in the face of vibration load, it will still loosen due to vibration, which will eventually lead to connection failure. Therefore, it is necessary to propose a combined locknut assembly

Abstract

The invention discloses a combined type locknut component. The combined type locknut component comprises a first nut, an anti-loosing clamping piece, a second nut, an auxiliary fastening bolt and a reset spring; compared with the prior art, the combined type locknut component is simple in structure and reasonable in design, can effectively absorb vibration load, guarantees the stability and reliability of connection of the bolt for a long time, and can also recycle the other components in a way of replacing a damaged component, thus lowering the using cost.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to a combined locknut assembly. 【Background technique】 [0002] Threaded fasteners are widely used in fastening connections between various mechanical structures, involving many industries and fields such as ships and vehicles. They are easy and convenient to disassemble, and have a good fastening effect in a short time. However, during the working process of existing threaded fasteners, due to the influence of device vibration, impact, and working condition changes, there will always be loosening and falling off, resulting in a decrease in fastening force, etc., and even lead to connection failure and falling off, resulting in huge Potential safety hazards and even personal and property losses. [0003] In order to solve this problem, people have invented anti-loosening nuts. The anti-loosening means of existing anti-loosening nuts are roughly divided into two types: the first...
