Multi-angle adjusting oil pipe assembly

Abstract

The invention relates to a multi-angle adjusting oil pipe assembly, which comprises a first joint, a second joint, a third joint, a sleeve pipe and an oil pipe; an oil or gas passage is arranged in each joint, the first end of the second joint is rotationally connected with the cylinder cover of a shock absorber, the first end of the oil pipe is sleeved to the second end of the second joint, and the second end of the second joint is clamped by the sleeve pipe so as to fix the first end of the oil pipe; the third joint is a rotary connecting part; the second end of the oil pipe is sleeved to the part of the third joint with a uniformly arranged bulges and is clamped and fixed to the third joint by the sleeve pipe, the other end of the third joint is rotationally connected with one end of the first joint, the other end of the first joint is rotationally connected with the outlet of a nitrogen tank, a double adjusting valve is arranged at the outlet of the nitrogen tank, and the double adjusting of a gas circuit or an oil circuit is realized through the double adjusting valve.

Description

technical field [0001] The invention relates to the field of shock absorbers, and more specifically, the invention relates to a multi-angle adjustment oil pipe assembly. Background technique [0002] The existing shock absorber with an oil-gas tank in the prior art includes a main oil cylinder and an oil-gas tank. The main oil cylinder and the oil-gas tank are connected by a pipeline. A piston rod is arranged in the main oil cylinder. When an external force acts on the piston rod, The oil in the main oil cylinder enters the oil and gas tank through the pipeline. The upper part of the oil and gas tank stores oil and the lower part stores gas. The two ends of the pipeline are respectively connected to the main oil cylinder and the oil and gas tank through joints. [0003] At present, the joints used on the market include a first connecting pipe and a second connecting pipe. One end of the first connecting pipe is the first connecting end, and the first connecting end is used t...

Problems solved by technology

[0003] At present, the joints used on the market include a first connecting pipe and a second connecting pipe. One end of the first connecting pipe is the first connecting end, and the first connecting end is used to fix the main oil cylinder or the oil and gas tank. The other end is closed, the closed end of the first connecting pipe is provided with a limit block, one end of the second connecting pipe is provided with a sleeve, and the other end is the second connecting end, the second connecting end is used for connecting pipelines, and the sleeve is sleeved on On the outer wall of the first connecting pipe, a diversion hole is provided on the outer wall of the first connecting pipe corresponding to the position of the casing, the first connecting pipe and the second connecting pipe are connected through the diversion hole, and a hole is provided between the casing pipe and the limit block. There is a sealing ring, and there is also a sealing ring between the main oil cylinder or the oil and gas tank and the casing. In order to prevent the oil from leaking out, the sealing ring is tightly pressed on both sides of the casing, so that the casing cannot be connected to the first connection. The pipe rotates, thereby limiting the relative position of the first connecting pipe and the second connecting pipe, which in turn restricts the installation environment of its shock absorber. If the relative position of the main oil cylinder and the oil and gas tank is changed forcibly, it is easy to cause deformation and shortening of the pipeline Life, the oil flow is not smooth, affecting the performance of the shock absorber
