Sealing structure of tapered slip ring with self-compensating property

The invention discloses a sealing structure of a tapered slip ring with a self-compensating property, which comprises a tapered slip ring, an O-ring, a cylinder barrel and a shaft sleeve, wherein the O-ring is arranged in a sealing ring groove of the cylinder barrel; a mobile annular retaining ring is arranged between the O-ring; the tapered slip ring is arranged between the cylinder barrel and the shaft sleeve and the cross section is a right triangle; an elastic element is arranged on the end face of the slip ring; the tapered slip ring moves rightward along the inclined plane of the shaft sleeve under the action of the elastic element and the internal pressure; the O-ring is extruded when the slip ring moves rightward; the deformed O-ring reacts on the slip ring as the diameter compression ratio of the cross section changes along with the internal pressure of a sealing cavity; and the contact pressure on the dynamic sealing surface of the slip ring is wavy to form serrated sealing effect.
