ANTI-DEFORMATION HOOK-EMBEDDED CONNECTION TYPE COMBINED SEALING RING FOR HYDRAULIC CYLINDER AND AIR CYLINDER

摘要

An anti-deformation hook-embedded connection type combined sealing ring for a hydraulic cylinder and an air cylinder. The combined sealing ring is formed by connecting a sealing ring (1) and an auxiliary ring through a hook-embedded type connector. The hook-embedded type connector is formed by an embedding block and a groove that are matched in shape, and the embedding block is of an anti-disengaging structure with an opposite acting force oblique angle. The anti-disengaging structure uses a shape whose front portion horizontal size is larger than a rear end horizontal size, or uses an anti-disengaging barbed shape whose hook end is less than 90 degrees, opposite acting force can be exerted on disengaging, and effective locking is achieved. The hook-embedded type connector combines and connects sealing rings in a combined sealing piece for mutual locking and sealing, oil in sealed portions of a system can be prevented from leaking to the interior of the system or the exterior of the system, serious dislocation and disengaging caused by squeezing of sealing pieces is prevented in the situations in which a device shaft swings severely and lateral load is large, a sealing capability is improved, and reliability of device operation is ensured.
