Description

Mute mechanical shaft Technical Field The utility model relates to the technical field of mechanical shaft silencing, in particular to a silencing mechanical shaft. Background The mute mechanical shaft is a special mechanical keyboard shaft body, and noise generated during key triggering and rebound is reduced through special design on the basis of keeping unique hand feeling and feedback of the mechanical shaft. At present, the axis of a mute mechanical shaft in the market is directly contacted with the bottom surface, the hard contact of the axis and the lower cover is not buffered, the resonance is relatively large, and noise can be generated in the pressing use process of the mechanical shaft. Therefore, there is a need for a silent mechanical shaft to solve the above problems. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a mute mechanical shaft. The sound-deadening device has the advantages that the silicon rubber ring and the rubber ring are added at the contact part of the shaft lever and the sound-deadening column, so that the condition that the axle center is directly contacted with the bottom surface of the lower cover to generate larger resonance noise is avoided. In order to achieve the above purpose, the present utility model adopts the following technical scheme: A silent mechanical shaft, comprising: a mechanical shaft body; The mechanical shaft comprises a mechanical shaft body, a first silencing assembly and a second silencing assembly, wherein the mechanical shaft body is used for silencing and denoising, the first silencing assembly and the second silencing assembly are arranged in the mechanical shaft body, the first silencing assembly comprises a silencing column for buffering the impact of a shaft rod of the mechanical shaft body, and the second silencing assembly comprises silencing holes for buffering airflow during the movement of the shaft rod. Through the technical scheme, the integral design of the mechanical shaft can effectively reduce noise generated in the use process of the mechanical shaft, and quieter use experience is provided for users. The mechanical shaft body comprises an upper cover, a shaft core and a lower cover, wherein the bottom of the shaft core is fixedly connected with a shaft lever, a spring is arranged on the circumferential outer wall of the shaft lever, and the spring is arranged between the upper cover and the lower cover.
