The inner cavity of the cylinder between the adjusting cylinder plug and the fixed cylinder plug is used as an adjustable medium receiving area. The fixed cylinder piston is provided with a built-in gas spring damping structure, which includes an inner cylinder, a piston is provided inside the inner cylinder, and a piston rod is connected to the piston. The adjustable medium receiving area is connected to the inner cavity of the inner cylinder of the built-in gas spring damping structure, forming a damping structure with an adjustable amount of damping medium in the built-in gas spring damping structure, and thus forming a gas spring structure with adjustable damping size.

[0006] Furthermore, an adjusting gas inlet hole is provided on the fixed end cap, which connects the space between the fixed end cap and the adjusting cylinder plug.

[0007] Furthermore, cylinder plug seals are provided at the connection points of the adjusting cylinder plug, the fixed cylinder plug, and the cylinder barrel.

[0008] Furthermore, a damping medium flow hole is provided on the fixed cylinder plug, and the damping medium flow hole is connected to the inner cavity of the inner cylinder.

[0009] Furthermore, the inner cylinder is provided with an inner cylinder section air exchange plate, and the inner cylinder section air exchange plate is provided with an air exchange hole, which connects the inner cylinder and the cavity between the cylinder.

[0010] Furthermore, the piston rod penetrates the piston rod end cap, and the piston rod end cap is provided with a piston rod sealing skeleton that is used in conjunction with the piston rod.

[0011] Furthermore, end caps, piston rod end caps, and cylinder inner cavity connections are all equipped with end cap seals.

[0012] Compared with the prior art, this utility model can adjust the amount of damping medium in the gas spring damping structure used as the damping part, forming a damping structure with adjustable damping value to meet the application occasions with varying damping values.
