Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Referring to Fig. 1 and Fig. 2, a kind of compact type bilayer with reset function of a preferred embodiment of the present invention is viscous
Damper, including first end cover 2, First piston bar 3, the first spring 4, first piston 5, second piston 6, second spring 7, interior oil
Cylinder 8, outer oil cylinder 9, second end cover 10, the first damping oil 13, the second damping oil 14, third end cap 15, the 4th end cap 16；
Wherein inner cylinder 8 is hollow cylinder, and first end cover 2 and second end cover 10 are separately mounted to the left and right of inner cylinder 8
Both ends, the metal material that the material selection of inner cylinder 8 has structural strength relatively good, in first end cover 2 and second end cover 10
It is provided with mounting hole, First piston bar 3 passes through first end cover 2 and second end cover 10 and installs to be had in oil cylinder 8 to interior, first piston
5 be fixedly connected in First piston bar 3 be located at it is interior have in oil cylinder 8, the second damping oil 14 is located in inner cylinder 1, the first spring 4
One end connects 2 one end of first end cover and connects first piston 5, and when First piston bar 3 is not by external force, first piston 5 is close to second end
Lid 10；One end of First piston bar 3 is fixedly connected with the first lifting lug 1.When the first lifting lug 1 receives pulling force, first piston
Bar 3 drives first piston 5 to be displaced outwardly, and the second damping oil 14 can flow into piston another side by the through-hole 51 on first piston 5,
First piston 5 will squeeze the first spring 4 simultaneously.
For circular ring shape, it is fixed on 8 outer wall of inner cylinder second piston 6, is equivalent to the piston that inner cylinder 8 is second piston 6
Bar, third end cap 15 and the 4th end cap 16 also for circular ring shape and are respectively fixedly connected with outer oil cylinder 9 or so two in hollow cylinder
End, third end cap 15 and the 4th end cap 16 be respectively sleeved on 8 outer wall of inner cylinder, and the first damping oil 13 is located at inner cylinder 8 and outside
Between oil cylinder 9,7 one end of second spring is fixed on one end in second piston 6 and is fixed on the 4th end cap 16, at second spring 7
Second piston 6 is close to the 4th end cap 16 when not by external force.Inner cylinder 8 can be by driving second piston 6 to the by external force
The movement of three end caps 15, and then second spring 7 is stretched, the first damping oil 14 can flow into piston by the through-hole in second piston 6
Another side.
The viscosity of first damping oil 13 is greater than the viscosity of the second damping oil 14, this is in order to which first piston and second piston exist
When receiving external force, first piston preferential motion.
Through-hole 51 is provided in 5/ second piston 6 of first piston.
