Description

Damping force mechanical adjusting mechanism of shock absorber Technical Field The utility model relates to the technical field of vibration absorbers, in particular to a mechanical damping force adjusting mechanism of a vibration absorber. Background The requirements of the vehicle on the damping strength of the shock absorber can be changed along with the changes of the running conditions such as load, road conditions and the like. When the driving condition is changed, for example, the damping force of the shock absorber cannot be adjusted correspondingly, the shock absorbing effect is difficult to be satisfied, and the comfort of the vehicle is seriously affected. Currently, with the continuous rise of the technology of various shock absorber manufacturers and the needs of users, various shock absorbers with adjustable damping force exist on the market; When the existing partial shock absorber carries out damping force adjustment operation, the flow velocity of oil in the working cavity is adjusted through the adjusting valve, so that the purpose of controlling the damping force of the shock absorber is achieved, but in the actual use process, the accurate control of the flow velocity of the oil cannot be guaranteed, the effective adjustment of the damping force of the shock absorber is not facilitated, and the comfort of a vehicle is affected. Disclosure of utility model In view of the above, the utility model provides a mechanical adjusting mechanism for damping force of a shock absorber, which adjusts the flow of oil through blocking adjustment of an oil passing hole, thereby being beneficial to realizing effective adjustment of damping force of the shock absorber and improving driving pleasure. In order to solve the technical problems, the utility model provides a damping force mechanical adjusting mechanism of a shock absorber, which comprises a shock absorber body, wherein a compression valve assembly is arranged in the shock absorber body, an adjusting needle seat corresponding to the compression valve assembly is arranged in the shock absorber body, a damping adjusting needle is arranged in the adjusting needle seat, the compression valve assembly axially corresponds to the damping adjusting needle, and the damping adjusting needle can move back and forth towards the compression valve assembly and is used for adjusting the blocking condition of an oil passing hole in the compression valve assembly.
