Abstract

The invention discloses a cylinder head gasket structure with annular sealing rubber ribs. The cylinder head gasket structure with the annular sealing rubber ribs comprises a gasket body, wherein the gasket body is of a rectangular structure, two corners of one end of the gasket body are in bevel edge transition, air cylinder holes are distributed in the gasket body, installing holes, square locating holes and water holes are distributed in the peripheries of the air cylinder holes, the annular sealing protruding rib is distributed on the outer edge of the gasket body, sealing ribs are arranged at the outer edges of the installing holes respectively, and the inner edge of each air cylinder hole is coated with a silicone rubber sealing layer. According to the cylinder head gasket structure with the annular sealing rubber ribs, the gasket body can be conveniently manufactured, materials are saved, and the production cost is reduced; the edge of the whole gasket body is sealed through the structure of the annular sealing protruding rib, and the annular sealing protruding rib is large in sealing pressing force and good in sealing performance; and local sealing performance of the cylinder head gasket structure is ensured through the structure of the silicone rubber sealing layer of each installing hole, the silicone rubber sealing layer of each square locating hole and the silicone rubber sealing layer of each air cylinder hole.

Description

A kind of head gasket structure with annular caulking gum muscle
Technical field
The present invention relates to cylinder seal technical field, relate in particular to a kind of head gasket structure with annular caulking gum muscle.
Background technique
Existing gasket structure design is improper, in order to increase its sealability, mostly adopts multi-layer structure, and multi-layer structure certainly exists certain drawback, as inconvenient in manufacturing, finished product is high, in order to reduce production costs, therefore need to improve the structure of individual layer shim body.
Summary of the invention
The object of the invention is in order to make up the deficiency of prior art, a kind of head gasket structure with annular caulking gum muscle is provided.
The present invention is achieved through the following technical solutions:
A kind of head gasket structure with annular caulking gum muscle, include the shim body of the structure that is rectangle, it is characterized in that: two corners of one end of described shim body are respectively hypotenuse transition, in described shim body, be distributed with cylinder-bore, the outer periphery of described cylinder-bore is distributed with mounting hole, square positioning hole, water hole, the outer edge of described shim body is distributed with ring packing convex tendon, the outer edge of described mounting hole is respectively equipped with sealed muscle, and the inside edge of described cylinder-bore is coated with silicone rubber seal layer.
Advantage of the present invention is:
The present invention coordinates by structure and one end hypotenuse transitional structure of individual layer shim body, can facilitate being processed into of shim body, saved material, reduced cost of production, simultaneously by the structure of ring packing convex tendon, the edge of whole pad has been sealed, and the sealing impacting force of ring packing convex tendon is large, good seal performance, the structure of the silicone rubber seal layer by mounting hole, square positioning hole and cylinder-bore, has guaranteed the sealability that it is local.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Referring to accompanying drawing, a kind of head gasket structure with annular caulking gum muscle, include the shim body 1 of the structure that is rectangle, two corners of one end of shim body 1 are respectively hypotenuse transition, in shim body 1, be distributed with cylinder-bore 3, the outer periphery of cylinder-bore 3 is distributed with mounting hole 4, square positioning hole 5, water hole 6, and the outer edge of shim body 1 is distributed with ring packing convex tendon 2, the outer edge of mounting hole 4 is respectively equipped with sealed muscle 7, and the inside edge of cylinder-bore 3 is coated with silicone rubber seal layer 8.
