Diameter and the outer diameter for being less than outer ring damping fin, the periphery of annular outer ring damping fin are matched with interior lower cylinder inner wall, the upper cylinder
The inner sidewall of lateral wall or interior lower cylinder is equipped with the limited block of the inner ring damping fin position of limitation lowest part；Interior lower cylinder lower part is set
There is at least one side through hole, liquid level is marked in bottom base no more than the damping grease on interior lower cylinder along height.
As a preferred solution, several ventholes are equipped on the upper cylinder wall at sealing plate lower surface.
As a preferred solution, Anchoring chain is equipped between the sealing plate and bottom base bottom plate.
As a preferred solution, the bottom base bottom plate is equipped with the lower positioning ring of insertion spring bottom end；On described
Sealing plate in pedestal is equipped with the upper positioning ring of insertion spring upper end.
As a preferred solution, the top base includes top plate, the annular seating that surface under the top plate is arranged, annular seating
Periphery is arranged with the shield that wall thickness is no more than 2mm, and the lower end of shield is located at the periphery on bottom base top.
The beneficial effects of the invention are as follows：It is movably equipped with from top to bottom on the outer wall being located in bottom base due to upper cylinder several
Annular inner race damping fin, movable sleeve is equipped with annular outer ring damping fin between adjacent annular inner ring damping fin on upper cylinder outer wall,

All to match with interior lower cylinder inner wall, the lateral wall of the upper cylinder is equipped with the limit of the inner ring damping fin position of limitation lowest part
Block；Interior lower cylinder lower part is equipped at least one side through hole, interior when centrifuge generates vibration when top base compression moves down
The damping grease being flooded between circle damping fin and outer ring damping fin can play very well inner ring damping fin while absorbing impact
Supporting role can greatly promote the damping effect of damper to play the role of support to top base；And inner ring hinders
The damping grease being flooded between Buddhist nun's piece and outer ring damping fin can the upper cylinder outer wall to top base play the role of circumferentially supporting, make
Obtain the case where top base is not in double swerve substantially.
Due to being equipped with upper edge in bottom base lower than cylinder lower in edge on bottom base, effect is the damping grease when vibration generates
When extruding, damping grease is constantly creeped in lower cylinder upwards inside, overflow in lower cylinder upper end, flow under folder between cylinder and bottom base
It in layer, avoids spilling over the external world, and interior lower cylinder bottom is equipped with a side through hole, making damping grease, gradually levelling returns in interior lower cylinder.
Due to being equipped with several ventholes on upper cylinder wall at sealing plate lower surface, so that sealing plate and resistance when damper is pressurized
Air between Buddhist nun's rouge can be discharged from, avoid air be pressurized in confined space generate bounce act on top base so that
Damper can preferably work.
Due to being equipped with Anchoring chain between sealing plate and bottom base bottom plate, top base uplink is avoided to be detached from bottom base.
Since bottom base bottom plate is equipped with the lower positioning ring of insertion spring bottom end；Sealing plate in the top base is equipped with embedding
Enter the upper positioning ring of spring upper end, so that the installation positioning of spring is more convenient.
Since top base includes top plate, the annular seating on surface under the top plate is set, and annular seating periphery is arranged with wall thickness and does not surpass
The shield of 2mm is crossed, the lower end of shield is located at the periphery on bottom base top, convenient for the suit of top base and bottom base.
