Multi-stage damping shock absorber

The invention provides a multi-stage damping shock absorber. The multi-stage damping shock absorber comprises an elastic packaging housing, a primary buffer plunger, a primary shock absorbing and damping disc, a secondary buffer plunger, a secondary porous damping disc, a first viscous oil fluid and a second viscous oil fluid, wherein the primary buffer plunger, the primary shock absorbing and damping disc, the second buffer plunger and the second porous damping disc are all mounted in a cavity of the elastic packaging housing; the second buffer plunger is mounted on the second porous damping disc; the primary shock absorbing and damping disc is mounted on the secondary buffer plunger; the primary buffer plunger is mounted on the primary shock absorbing and damping disc; the second viscous oil fluid is placed at the bottom of the cavity of the elastic packaging housing; and the first viscous oil fluid is placed at the upper part of the cavity of the elastic packaging housing. The multi-stage damping shock absorber is simple in structure, excellent in shock absorption, skillful in design and favorable in performance, and is convenient and practical.
