Problems solved by technology

Now in the field of aerospace, high lock nuts are usually used for structural connection. 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, and after installation It can only be disassembled by means of destruction, 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 costs

Embodiment Construction

[0023] The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.

[0024] Such as Figure 1 to Figure 6 As shown, the hexagon self-locking nut of the present invention includes a hexagon nut body 10 provided with a threaded hole 11 and an extension part 20 integrally connected with the hexagon nut body 10 .

[0025] Specifically, as figure 1 As shown, the hexagonal nut body 10 is provided with an outer hexagonal surface 12 . The extension portion 20 extends obliquely and outwardly from the lower end of the hex nut body 10 . The extension 20 has an inclined outer hexagonal surface 22 . The inclined outer hexagonal surfaces 22 intersect with the outer hexagonal surfaces 12 of the hex nut body 10 one by one to form an included angle. In this embodiment, the intersecting angles are 150 degrees. A triangular surface 23 is respectively provided between two adjacent surfaces of the inc...

Abstract

A hexagonal surface self-locking nut is provided with a hexagonal nut body provided with a threaded hole. The hexagonal surface self-locking nut is characterized in that micro-deformation portions distributed at intervals along the circumference of the hexagonal nut body are evenly arranged on the hexagonal nut body, the micro-deformation portions are produced by exerting radial deformation pressure on the side wall of the hexagonal nut body, and the micro-deformation portions enable the hexagonal surface self-locking nut to achieve self-locking. According to the hexagonal surface self-locking nut, the side wall of the hexagonal nut body is extruded in a three-point extrusion mode, so that the hexagonal nut body and a thread in the threaded hole generate micro-deformation so as to achieve the stable and reliable self-locking effect, a technological portion in a high-lock nut can be replaced, the reliable self-locking effect is achieved, raw materials can be greatly saved, and manufacturing cost is lowered. In addition, the hexagonal surface self-locking nut has the advantages of being simple in structure, convenient to install, capable of being used repeatedly, light in weight, wide in application range and the like.

Description

【Technical field】 [0001] The invention relates to a self-locking nut, in particular to a hexagonal self-locking nut used in aerospace. 【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. Now in the field of aerospace, high lock nuts are usually used for structural connection. Although high lock nuts can meet t...
