Abstract
The utility model discloses a cylinder gasket structure with good stability. The cylinder gasket structure comprises a gasket body, wherein cylinder holes, water holes, mounting holes and positioning holes are distributed in the gasket body; two end surfaces of the gasket body are coated with silicone rubber layers respectively; positioning grooves are distributed in two sides of the gasket body respectively; buckles are distributed on two sides of the positioning groove on one side and the two ends of the gasket body respectively; peripheries of the water holes, the mounting holes and the positioning holes on the other side are coated with nylon plastic layers respectively; sealing bulging ribs are arranged on outer edges of the cylinder holes; and edges outside the sealing bulging ribs are coated with blue butadiene-acrylonitrile rubber layers. According to the cylinder gasket structure, the structure of the buckles and the positioning grooves is adopted, so that the cylinder gasket structure is convenient to install and fix, good in stability and not easy to shift; and the structure of the silicone rubber layers on the gasket body, the nylon plastic layers of the water holes, the mounting holes and the positioning holes as well as the sealing bulging ribs and the blue butadiene-acrylonitrile rubber layers of the cylinder holes is adopted, and a plurality of sealing materials are combined, so that the cylinder gasket structure is good in sealing performance and applicable to sealing in various environments.
Description
Technical field
The utility model relates to cylinder seal technical field, relates in particular to the head gasket structure that a kind of stability is good.
Background technique
Existing head gasket is in order to increase sealability, the head gasket body that mostly adopts multiple layer metal material to form, although increased impacting force, improved to a certain extent sealability, but its cost is high, and manufacturing is inconvenient, installs fixing inconvenient simultaneously, during use, be easily shifted, affect its sealability.
Model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and the head gasket structure that a kind of stability is good is provided.
The utility model is achieved through the following technical solutions:
The head gasket structure that a kind of stability is good, include shim body, in described shim body, be distributed with cylinder-bore, water hole, mounting hole and positioning hole, it is characterized in that: in the both ends of the surface of described shim body, be coated with respectively silastic-layer, the both sides of described shim body are distributed with respectively positioning groove, and the positioning groove both sides of a side and the two ends of shim body are distributed with respectively buckle, the water hole of opposite side, mounting hole and positioning hole periphery are coated with respectively Nylon layer, the outer edge of described cylinder-bore is provided with seal bead, edge outside described seal bead is coated with blue butyronitrile glue-line.
The utility model has the advantages that:
The utility model is by the structure of buckle and positioning groove, it installs convenient fixing, stability is good, be not easy displacement, by the structure of the Nylon layer of the silastic-layer in shim body, water hole, mounting hole and positioning hole and the seal bead of cylinder-bore and blue butyronitrile glue-line, the combination of multiple sealing material, it is good seal performance not only, and applicable to all-environment sealing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
