[0010] The utility model further sets up that the shock-absorbing layers and the sealing layers are annular, and the annular outer ring of the sealing layer is provided with a sealing skirt.

[0011] By adopting the above technical scheme, the sealing skirt can abut against the shaft wall and is mainly used to increase the sealing effect.

[0012] The utility model further sets up that the annular inner ring of the shock-absorbing layer is provided with a thickened inner ring.

[0013] By adopting the above technical scheme, the thickened inner ring increases the structural strength.

[0014] The utility model further sets up: the sealing skirt includes sealing section and support section, sealing section and sealing laminated layer integral moulding, the support section protrudes in sealing section direction setting towards another sealing laminated layer.

[0015] Through adopting above-mentioned technical scheme, the mutual abutment of support section can play certain supporting effect.

[0016] The utility model further sets up: the buffer cavity is even interval setting.

[0017] Through adopting above-mentioned technical scheme, interval setting multiple buffer cavities, can evenly distribute impact force, thereby strengthen shock attenuation effect. BRIEF DESCRIPTION OF DRAWINGS
