Guide anti-loosening thread pair structure

Abstract

The invention belongs to the technical field of mechanical thread pair connection, adjustment of instruments and meters and electric signal fine adjustment of communication electronic equipment, and particularly relates to a guide anti-loosening thread pair structure. The structure comprises an internal thread guide plate and an elastic anti-loosening plate fixed together with the internal thread guide plate, wherein the internal thread guide plate and the elastic anti-loosening plate form an internal thread anti-loosening structure, the internal thread anti-loosening structure and a screwed-in screw form an anti-loosening thread pair, and at least two anti-loosening elastic pieces machined on the elastic anti-loosening plate are evenly distributed along the circumference with the thread center as the circle center; the heights of the anti-loosening elastic pieces are sequentially and uniformly distributed along the lead angle of the thread; and the end parts of the anti-loosening elastic pieces can be elastically embedded into the inner sides of two adjacent screw teeth on the screw. According to the guide anti-loosening thread pair structure, the anti-loosening effect of a screw can be well achieved, meanwhile, convenience for later adjustment can be guaranteed, and the anti-loosening thread pair structure is good in anti-loosening self-locking force consistency and suitable for large-scale application.

Description

technical field [0001] The invention belongs to the technical field of mechanical screw pair connection, instrumentation adjustment and electrical signal fine-tuning of communication electronic equipment, and specifically relates to a guiding and anti-loosening screw pair structure. Background technique [0002] In the application of machinery, electronics, and instrumentation with screw thread adjustment, it is often necessary to adjust the mechanical assembly position through the fine adjustment of the thread, and adjust the electrical signal in the electronics. [0003] At present, there are mainly two types of guided anti-loosening thread pairs: [0004] 1. Open a small groove on the external thread, as attached figure 1 As shown, a small piece of elastic material, such as nylon rod 6, is embedded in the small groove. When the screw is screwed into the nut, it meets the nylon rod 6. After the screw is continued to be screwed in, the nylon rod 6 plays a Anti-loose effec...

Problems solved by technology

[0006] Although the above two oriented anti-loosening thread pair structures can achieve a certain anti-loosening effect, the consistency of the anti-loosening self-locking force is difficult to control, which is not conducive to large-scale applications and is not conducive to multiple adjustments of the structure
