Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering, and in particular to a rotating oil pipe structure for a shock absorber. Background Technology

[0002] To meet the needs of different installation environments, the shock absorber oil circuit joint needs to be designed as a rotatable structure. Currently available rotatable shock absorber joints can be found in Chinese Utility Model Patent Application No. CN202220949419.1, entitled "A Shock Absorber Joint." While existing rotatable shock absorber joints enhance the sealing at the connection between the oil pipe, piston cylinder, and oil cup, they suffer from several drawbacks. Firstly, their structural design is complex, resulting in low durability and high replacement costs. Secondly, they restrict the freedom of movement of the oil pipe, making adjustments to the relative angle and orientation of the oil cup and piston cylinder more cumbersome. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rotating oil pipe structure for a shock absorber that is easy to adjust while ensuring sealing.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a rotating oil pipe structure for a shock absorber, including a piston cylinder tail seat, the piston cylinder tail seat being rotatably connected to one end of the oil pipe through a first joint, the other end of the oil pipe being rotatably connected to a third joint through a second joint, the third joint being screwed to an oil cup, the rotation axis of the first joint and the rotation axis of the second joint being coaxial with the axis of the oil pipe, the rotation axis of the third joint being perpendicular to the rotation axis of the second joint, and the oil holes of the piston cylinder tail seat, the first joint, the oil pipe, the second joint, the third joint and the oil cup being connected in sequence.

[0005] Furthermore, the inner wall of the oil hole of the piston cylinder tailstock is provided with a stepped surface, and the first joint rotates and seals with the stepped surface.

[0006] Furthermore, the stepped surface has a first step surface, and the outer wall of the first joint is provided with a first sealing ring, which is interference-fitted with the first step surface.

[0007] Furthermore, the outer wall of the first connector is provided with an annular mounting groove, and the first sealing ring is disposed in the annular mounting groove.

[0008] Furthermore, the stepped surface has a second step surface, the second step surface is provided with a first annular groove, the outer wall of the first connector is provided with a second annular groove, and a clamp is provided between the first annular groove and the second annular groove.

[0009] Furthermore, both the first and second connectors are equipped with pagoda-shaped male connectors for insertion into the oil pipe.

[0010] Furthermore, a first joint sealing sleeve is provided on the connection between the first joint and the oil pipe, and a second joint sealing sleeve is provided on the connection between the second joint and the oil pipe.

[0011] Furthermore, the outer wall of the first connector is provided with a first limiting boss for limiting the sealing sleeve of the first connector, and the outer wall of the second connector is provided with a second limiting boss for limiting the sealing sleeve of the second connector.

[0012] Furthermore, the second connector is provided with a connection hole, and the third connector is rotatably connected to the connection hole.

[0013] Furthermore, the third connector is provided with an external thread, and the oil cup is provided with a screw hole that engages with the external thread.

[0014] The beneficial effects of this utility model are as follows: A rotating oil pipe structure for a shock absorber uses a first connector to connect the piston cylinder tailstock and the oil pipe, a second connector to connect the oil pipe and a third connector, and the third connector to connect the oil cup. Since the rotation axes of the first and second connectors are coaxial with the axis of the oil pipe, and the rotation axis of the third connector is perpendicular to the rotation axis of the second connector, it is possible not only to flexibly rotate the connection point between the oil pipe and the piston cylinder tailstock and the second connector, but also to rotate the connection point between the second and third connectors. The structural design is simpler, and it is more convenient to adjust the relative angle and orientation of the oil cup and the piston cylinder. Attached Figure Description
