Abstract

The utility model provides an adjustable shock absorber gas cylinder device, which is provided with a cylinder body, a penetrating piece and an adjusting piece. The penetrating piece penetrates through the bottle mouth of the bottle body and is provided with a through hole and a plurality of connecting channels. The perforation penetrates through the penetrating piece and is communicated with the inner space of the bottle body. The connecting channels are communicated with the through holes and the outer ring surface of the penetrating piece, and the sizes of the connecting channels are different. The adjusting piece is rotatably sleeved on the penetrating piece and is provided with an inlet and a selection hole. The inlet is formed on the outer surface of the adjusting piece, the selection hole penetrates through the adjusting piece, and the perforation can be selectively communicated with the inlet through one of the connecting channels. The utility model has the advantage that the selection holes are selectively communicated with different connecting channels by rotating the adjusting piece, thereby adjusting the flow rate of the working fluid flowing into the bottle body.

Description

Adjustable gas cylinder device for shock absorber Technical Field The present utility model relates to a shock absorber device, and more particularly, to an adjustable shock absorber gas cylinder device. Background Shock absorbers are often installed on vehicles such as locomotives and automobiles to reduce the shock caused by road surfaces when the vehicles run, so that drivers and passengers have comfortable riding experience. The shock absorber generally has a spring and a cylinder device. Vibration generated by the vehicle on the uneven road is mainly absorbed by the springs, the springs can generate rebound vibration after absorbing the vibration, and at the moment, the piston device is needed to slow down the expansion speed of the springs. In order to make the shock absorbing capability of the shock absorber meet the requirement of users, the conventional shock absorber is often provided with a shock absorbing adjusting device on the gas cylinder device, and has a working fluid flowing back and forth between the two devices. The conventional shock absorbing adjusting device utilizes an oil needle to selectively shield the flow passage, and controls the speed of the working fluid flowing into the piston device by the shielded area of the flow passage. However, when the oil needle is used, the user cannot know the degree of shielding the flow passage by the oil needle and cannot accurately regulate the flow condition of the working fluid because the oil needle is arranged in the shock absorber. Therefore, how to control the flow rate of the working fluid more precisely is a problem to be solved in the industry. Disclosure of utility model The main objective of the present utility model is to provide an adjustable gas cylinder device for a shock absorber, which is used for solving the problems that the user of the existing shock absorber adjusting device cannot know the degree of the shielding flow passage of the oil needle and cannot accurately adjust the flow condition of the working fluid. In order to achieve the above object, the present utility model provides an adjustable shock absorber gas cylinder device, which comprises: A bottle having: a piston member movably disposed in the bottle body; a penetrating piece which penetrates through the bottle mouth of the bottle body and is provided with: a perforation penetrating the penetrating member and communicating with the internal space of the bottle body; The connecting channels are different in size and are communicated with the through hole and the outer ring surface of the penetrating piece; An adjusting member rotatably sleeved on the penetrating member, and having: an inlet formed on an outer surface of the adjustment member; A selection hole penetrating the adjusting piece and selectively connecting the through hole with the inlet through one of the connecting channels. An adjustable shock absorber gas cylinder apparatus as described above, wherein, The adjusting member further has: a plurality of clamping grooves, the number of which corresponds to the plurality of connecting channels; The adjustable shock absorber gas cylinder device further comprises: The abutting piece is arranged in the penetrating piece and can selectively protrude out of the penetrating piece and be clamped in one of the clamping grooves; And the elastic piece is arranged in the penetrating piece and tends to push the abutting piece out towards the direction of the outer surface of the penetrating piece.
