Abstract

The utility model discloses an anti-extrusion deformation gasket comprising a gasket body consisting of a framework and a rubber body. A plurality of convex ribs are arranged on the inner side surface of the framework along the circumferential direction, arranged along the height direction of the framework and extend from the upper surface of the framework to the lower surface of the framework; strip-shaped through grooves matched with the convex ribs are arranged on the outer side surface of the rubber body, annular grooves are arranged in the middle of the inner side surface of the rubber body and annular bulges are arranged on the upper surface and the lower surface of the rubber body. The anti-extrusion deformation gasket has the following beneficial effects: as the framework and the rubber body are clamped and matched with each other by the convex ribs and the strip-shaped through grooves, the disassembly and assembly are convenient, a releasing space is provided for the deformation of the gasket, and the annular grooves also provide a releasing space for the deformation of the rubber body, so that the product is not easy to extrude and damage, and the sealing effect of the gasket is guaranteed; and the annular bulges arranged on the rubber body provide certain radian for the sealing surface, thus further guaranteeing the sealing effect.

Description

Anti-extrusion distortion packing ring
Technical field
The utility model belongs to the sealed member field, is specifically related to a kind of anti-extrusion distortion packing ring.
Background technique
Seal washer commonly used in the existing technology is made up of skeleton and rubber body, utilizes the interference fit between rubber body and the contact component, makes packing ring play seal action.But the side that seals on the rubber body is solid shape; After rubber body receives bigger extruding force; Can produce bigger distortion, and solid rubber body does not have for its distortion the space that discharges distortion to be provided, and do not provide the Free up Memory of rubber body tangential deformation between skeleton and the rubber body yet; Therefore very easily cause the breakage of packing ring, cause seal failure.And the wear resistance of existing packing ring is also relatively poor.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned existing technology, and a kind of anti-extrusion distortion packing ring is provided, and prevents that effectively packing ring is damaged, improves the sealing effect and the wear resistance of packing ring.
The technological scheme that the utility model adopted is: a kind of anti-extrusion distortion packing ring; Comprise the packing ring body that constitutes by skeleton and rubber body; The inner side surface of said skeleton along the circumferential direction is provided with some fins; Said fin extends to its lower surface along the setting of skeleton short transverse and by the skeleton upper surface; Said rubber body outer side surface is provided with the bar shaped groove with above-mentioned fin coupling, and the medium position of said rubber body inner side surface is provided with annular groove, and the upper surface and the lower surface of said rubber body are equipped with annular projection.
As preferably, said fin is evenly distributed on the said skeleton inner side surface.
As preferably, the sectional shape of said annular groove is circular arc.
As preferably, the sectional shape of said annular projection is circular arc.
The beneficial effect of the utility model is: because skeleton and rubber body are through fin and bar shaped groove clamping coupling; Both easy disassembly; Free up Memory is provided also for the packing ring tangential deformation; Annular groove also provides Free up Memory for the rubber body distortion, makes product be difficult for being extruded breakage, has guaranteed the sealing effect of packing ring; The annular projection that on rubber body, is provided with is that sealing surface provides certain radian, has further guaranteed the sealing effect of packing ring.
