Integrally-formed anti-skid anti-looseness self-locking screw rod, fastening assembly and tuning device

Abstract

The invention discloses an integrally-formed anti-skid anti-looseness self-locking screw rod, a fastening assembly and a tuning device. The screw rod comprises an integrally-formed screw rod body, thescrew rod body comprises a head portion and a body portion, the head portion comprises thread portions arranged in a spaced mode and an elastic portion located between the thread portions, the elastic portion is provided with an arc groove, and the arc groove and the thread portions are of an integrally-formed structure. Since the elastic portion is provided with the arc groove and located between the thread portions, when the screw rod body is adjusted, the purpose of self locking of the screw rod in the fastening assembly is achieved through springback torque produced by the arc groove structure on the elastic portion, the structure is smaller and more portable compared with a traditional non-self-locking screw rod, the fastening assembly with the self-locking screw rod is used in the tuning device since fine thread pitch fit is adopted in the self-locking way, the accuracy of adjusting the screw rod size is improved, adjusting time is shortened, and therefore the tuning device adopting the self-locking screw rod is stable relative to a traditional way and high in one-time passing rate.

Description

【Technical Field】 [0001] The invention relates to the technical field of tuning screws, in particular to an integrally formed anti-skid, anti-loosening and self-locking screw, a fastening component and a tuning device. 【Background technique】 [0002] The traditional tuning method uses silver-plated screws, stainless steel nuts, stainless steel washers, and aluminum cover plates to drill and tap to achieve the tuning function. Employees need to rotate the screw repeatedly to rub against other components during debugging, which is extremely easy to cause wear and slippage of the debugging position. The tightening force will gradually decrease, causing looseness, and generating debris into the resonant cavity, resulting in poor S-parameters and low first-pass rate of third-order intermodulation, increasing the probability of product rework and manufacturing costs. [Content of the invention] [0003] The purpose of the present invention is to solve at least one of the above-mentioned ...

AI Technical Summary

Problems solved by technology

[0002] The traditional tuning method is to realize the tuning function by drilling and tapping the silver-plated screw, stainless steel nut, stainless steel gasket, and aluminum cover plate. When debugging, the employee needs to rotate the screw repeatedly to rub against other parts, which will easily lead to wear and slip of the debugging position. The tightening force will gradually decrease, resulting in loosening, and debris entering the resonant cavity, resulting in poor S parameters and a low pass rate of third-order intermodulation, which increases the chance of product rework and manufacturing costs
