Abstract
The invention discloses an air cylinder gasket structure with a buckle. The air cylinder gasket structure comprises a gasket body, and an air cylinder hole, a water hole, a locating hole and an installation hole are formed in the gasket body. The air cylinder gasket structure is characterized in that the locating hole is a square locating hole, a cylinder hole retainer is arranged at the position of the air cylinder hole, buckle sides extending outwards and turned over outwards are distributed on the two sides of the gasket body respectively, a semi-circular clamping groove is further formed in one side of the gasket body, and the gasket body is coated with a polytetrafluoroethylene layer and a rubber layer. According to the air cylinder gasket structure with the buckle, through the structural design of the buckle sides, the semi-circular clamping groove and the square locating hole, the locating function of the gasket body is enhanced during installation of the gasket body, and the air cylinder gasket structure is good in stability and not prone to moving, and the sealing performance is enhanced and the use requirements are met through the structure combining the cylinder hole retainer, the polytetrafluoroethylene layer and the rubber layer.
Description
Technical field
The present invention relates to cylinder seal technical field, relate in particular to a kind of head gasket structure with buckle.
Background technique
The effect of head gasket is the microscopic void of filling up between cylinder block and head, guarantees that there is good sealing at junction plane place, and then guarantees that the sealing of firing chamber prevents that cylinder leakage tester and water jacket from leaking.Existing head gasket is simple in structure, and it is fixed and mostly adopts simple positioning hole and mounting hole that location is installed, and its poor stability, easily moves, and affects its sealability, can not meet usage requirement.
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 buckle is provided.
The present invention is achieved through the following technical solutions:
A kind of head gasket structure with buckle, include shim body, in described shim body, be distributed with cylinder-bore, water hole, positioning hole, mounting hole, it is characterized in that: described positioning hole is square positioning hole, described cylinder-bore place is provided with cylinder hole guard ring, the both sides of described shim body are distributed with respectively the button limit that stretches out and turn down, and one side is also provided with semicircle draw-in groove, are coated with polytetrafluorethylecoatings coatings and rubber layer in described shim body.
Advantage of the present invention is:
The present invention is by the structural design of button limit, semicircle draw-in groove, square positioning hole, strengthened shim body locating function when mounted, make its good stability, be not easy displacement, structure in conjunction with cylinder hole guard ring, polytetrafluorethylecoatings coatings and rubber layer, strengthen sealability, met usage requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Referring to accompanying drawing, a kind of head gasket structure with buckle, include shim body 1, in shim body 1, be distributed with cylinder-bore 2, water hole 3, positioning hole 4, mounting hole 5, positioning hole 4 is square positioning hole, and cylinder-bore 2 places are provided with cylinder hole guard ring 6, and the both sides of shim body 1 are distributed with respectively the button limit 7 that stretches out and turn down, and one side is also provided with semicircle draw-in groove 8, is coated with polytetrafluorethylecoatings coatings and rubber layer in shim body 1.
Claims (1)
