[0016] Example

[0017] See also Figure 1The utility model provides an anti-rotation connection structure between the gas tank and the main cylinder of the shock absorber, comprising a gas tank 1 and a main cylinder 2 arranged on one side of the gas tank 1. The main cylinder 2 and the gas tank 1 are rotatably connected through a connecting assembly, the connecting assembly is sleeved on one end of the main cylinder 2, and a cylinder cover 3 is arranged at one end of the connecting assembly. The cylinder cover 3 is sleeved on the end of the main cylinder 2. After the cylinder cover is locked, the axial movement of the connecting assembly is limited to prevent the connecting assembly from coming out during the rotation process. A piston rod group 4 is sleeved and connected inside one end of the main cylinder 2 close to the connecting assembly.

[0018] The connection assembly includes an adapter sleeve 5 and an anti-rotation sleeve 6 sleeved on the main cylinder 2, and the anti-rotation sleeve 6 and the adapter sleeve 5 are set as an integral structure. A connecting groove is provided on the side where the adapter sleeve 5 and the anti-rotation sleeve 6 contact each other, and a connecting protrusion 7 is clamped in the connecting groove, and the connecting protrusion 7 is fixedly connected to the anti-rotation sleeve 5. The adapter sleeve 5 and the anti-rotation sleeve 6 are connected into an integral structure by the clamping connection of the connecting groove and the connecting protrusion 7, which is simple in structure and strong and durable.

[0019] The anti-rotation sleeve 6 is provided with an opening, and two fixing plates 8 are fixedly connected at the opening. Through holes are provided on the two fixing plates 8, and radial locking screws 9 are provided in the through holes. A fixing piece is provided at the end of the radial locking screw 9. The fixing piece is a fixing nut, and the anti-rotation sleeve 6 is fixed to the main cylinder 2 by tightening the fixing nut. After the radial locking screw 9 is tightened, the friction force generated by the anti-rotation sleeve 6 and the main cylinder 2 limits its radial rotation, thereby preventing the adapter sleeve 5 from falling out during the rotation process.

[0020] One end of the adapter sleeve 5 away from the connection groove is rigidly connected to the gas tank 1. The rigid connection includes fixedly connecting the adapter sleeve 5 and the gas tank 1 together by welding, threaded connection, flange connection, etc.

[0021] During specific use, first connect the adapter sleeve 5 with the gas tank 1, then put the adapter sleeve 5 into the main cylinder 2, and then put the anti-rotation sleeve 6 on one end of the adapter sleeve 5, and insert the connecting protrusion 7 into the connecting groove to connect the adapter sleeve 5 and the anti-rotation sleeve 6 to form a whole. At this time, pass the radial locking screw 9 through the through holes of the two fixing plates 8 and tighten them with the fixing nut. After installing the connecting assembly, install the cylinder cover 3 on the end of the main cylinder 2. After installation, the gas tank 1 can be rotated 360 degrees around the main cylinder 2 at any angle, which is convenient for installation.

[0022] Therefore, the utility model adopts an anti-rotation connection structure between the gas tank and the main cylinder of a shock absorber with the above-mentioned structure. After the cylinder cover is locked, the axial movement of the connecting assembly is limited to prevent the connecting assembly from coming out during rotation; after the radial locking screw on the anti-rotation sleeve is tightened, the radial rotation is limited by the friction force generated by the anti-rotation sleeve and the main cylinder; by setting up the connecting assembly, when the shock absorber is installed on the vehicle, the gas tank can rotate 360 ​​degrees around the main cylinder, thereby improving versatility.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
