Self-adjusting detachable high-locking nut assembly

Abstract

The invention relates to the application field of connectors and fasteners, in particular to a self-adjusting detachable high-locking nut assembly. The self-adjusting detachable high-locking nut assembly comprises a concave spherical washer and a locking part, wherein the locking part comprises a working part and a process part which are of an integrated structure; the working part is of a three-section integrated structure from front to back, a front section is of a convex spherical structure, a middle section is an arc-shaped shoulder, and a rear section is of an outer-hexagonal structure; an inner threaded hole is formed in the working part; a flaring is formed in the front end of the inner threaded hole; and the front end of the concave spherical washer is a flat end surface, and the rear end of the concave spherical washer is a concave spherical structure matched with the convex spherical structure. The self-adjusting detachable high-locking nut assembly has the beneficial effects that 1, the front section is of the convex spherical structure and is matched with the concave spherical washer, and under the condition that a certain inclination angle exists in an interlayer, firm connection can still be realized in an exactly matched mode; 2, the middle section is the arc-shaped shoulder, a torque wrench does not collide with the surface of an assembly plate when a nut is disassembled, and therefore the protection effect can be achieved; and 3, the rear section is of the outer-hexagonal structure so that repeated use after installation can be realized.

Description

technical field [0001] The invention relates to the application field of connector fasteners, in particular to a self-adjusting detachable high lock nut assembly. Background technique [0002] Ordinary nuts will loosen due to vibration and other reasons during use. In order to solve the problem of loosening of nuts during use, people have invented self-locking nuts. The working principle of the self-locking nut is to achieve the function of anti-vibration and anti-loosening by increasing the friction force of the threaded connection. There are many types of self-locking nuts, which mainly include embedded nylon rings, special thread bottoms, and metal anti-loosening devices. For the aerospace field, in the connecting structure of the aircraft, in order to meet its flight requirements, it is usually necessary to use connecting parts with light weight and high fatigue strength. In the field of aerospace, high-lock nuts are usually used for structural connections. On the one ...

Problems solved by technology

In the field of aerospace, high-lock nuts are usually used for structural connections. On the one hand, although high-lock nuts can meet the self-locking requirements of the connection, their structure is more complicated, and they are usually used in conjunction with the process part and the working part. The existing working part is a cylindrical structure with a smooth outer surface, so it can only be disassembled by means of destruction after installation, and cannot be reused after disassembly, which makes its use more troublesome, and it is easy to cause a lot of waste of material resources, which is not conducive to saving cost

[0003] On the other hand, the existing high-lock nuts generally have a flat end face at the front end of the working part. If the installation interlayer has a certain inclination angle, the conventional high-lock bolt and nut joint connection cannot achieve a stable connection in this case.
