One-way rotation structure for anti-loosening mechanical fastening mechanism

Abstract

The invention relates to a one-way rotation structure for an anti-loosening mechanical fastening mechanism. It solves the technical problems that the existing fastening mechanism is prone to loosening and the like. The anti-loosening mechanical fastening mechanism includes a bolt body, and the bolt body has two threaded sections respectively connected with the compression nut and the anti-loosening nut, and the thread directions of the two threaded sections are opposite. The one-way rotation structure It includes an adjustment ring sleeved on the bolt body and located between the compression nut and the anti-loosening nut, and the first one-way unit and / or the first one-way unit is arranged between the lower end of the compression nut and the upper end of the adjustment ring. A second one-way unit is arranged between the side of the compression nut and the side of the adjustment ring. The advantages are: it can realize the one-way rotation of the compression nut and the adjustment ring, the connection strength is high, the rotation direction of the mechanical parts can be adjusted reliably, the stability is good, it can prevent loosening during connection, and ensure the anti-loosening function with anti-loosening function. The performance of the mechanical fastening mechanism is realized.

Description

technical field [0001] The invention belongs to the technical field of fasteners, and in particular relates to a one-way rotation structure used for an anti-loosening mechanical fastening mechanism. Background technique [0002] The screw pair fastening mechanism is a common threaded fastening mechanism. The most common fastening connection is a bolt and a nut that cooperate with each other. The threaded connection of the mechanical equipment connection is realized through the thread of the bolt. Bolts and nuts have good connection performance and simple structure, and are widely used in the field of mechanical equipment. However, bolts and nuts have the defect of easy loosening. With the frequent vibration of the equipment, the gap between the connecting parts increases, causing the bolts and nuts to loosen or even fall off. , In this way, for some mechanical connections, the connecting bodies are prone to separate from each other, and serious accidents are likely to occur....

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned scheme improves the problem that the existing bolts and nuts are easily loosened to a certain extent. Although the above-mentioned scheme is provided with several anti-skid grooves on the opposite top surfaces of the inner nut and the outer nut, the inner nut, the outer nut, and the bolts The starting point of the thread is uncertain, and the anti-skid groove is difficult to achieve the purpose of being locked together

Even if they can be accidentally stuck together, the solution still has the problem of low connection strength, a gap between the inner nut and the outer nut when the vibration is large, or the inner nut is easy to push the outer nut back, resulting in loosening between the inner nut and the connecting body, and Eventually, the outer nut and the inner nut will be separated from the bolt.
