The spring base stated is equipped with damping spring, is arranged with spring-loaded governor on the oil cylinder, the damping spring with it is described
Spring-loaded governor connects, the adjusting step that the spring-loaded governor differs equipped with several height, on the oil cylinder outer wall
Limited block is installed with, the limited block is abutted with any adjusting step.
Further, it is convexly equipped with hollow adjusting block on the spring-loaded governor.
Further, bottom valve is equipped with close to one end of oil cylinder seat in the oil cylinder, between the piston and the bottom valve
Working cylinder is formed, the working cylinder is interior filled with hydraulic oil；
Guide holder is additionally provided in the oil cylinder, the guide holder and the oil cylinder are set between one end of spring base
There is oil sealing, oil cylinder spring is equipped between the guide holder and the piston, the piston rod passes through the oil cylinder
Spring.
Further, the junction of the piston rod and the spring base is equipped with jam nut.
Further, cushion pad is also arranged on the piston rod, the cushion pad is abutted with the oil cylinder.
Further, it is equipped with beam on the spring base and oil cylinder seat.
Further, the adjusting step is in semicircle shape.
The beneficial effects of the utility model are：Better damping performance is provided, and pass through by the form of hydraulic pressure
The cooperation of spring-loaded governor and limited block so that commonly used person can also borrow the elasticity of adjustment spring easily, so that
Damper can preferably coordinate the use of vehicle.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the internal structure schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Reference Fig. 1~Fig. 2, a kind of spring adjustable type hydraulic damper, including oil cylinder seat 1 and spring base 2, the oil
Cylindrical oil cylinder 3 is provided in cylinder seat 1, piston 4 is equipped in the oil cylinder 3, piston rod is fixed on the piston 4
5, the other end of the piston rod 5 stretches out the oil cylinder 3 and affixed with the spring base 2, is set on the spring base 2
There is damping spring 6, spring-loaded governor 7, the damping spring 6 and the spring-loaded governor 7 are arranged on the oil cylinder 3
It connects, the adjusting step 8 that the spring-loaded governor 7 differs equipped with several height, it is fixed limited on 3 outer wall of oil cylinder
Position block 9, the limited block 9 are abutted with any adjusting step 8.Preferably, the adjusting step 8 is in semicircle shape,
Resistance can be reduced when adjustment spring is elastic so that it is more laborsaving, smooth to adjust process.
In the present embodiment, hollow adjusting block 10 is convexly equipped on the spring-loaded governor 7.It is common by screwdriver etc.
Tool is inserted into the hollow adjusting block 10, then can firmly agitate and be shifted on the spring-loaded governor 7 so that limited block 9
