Abstract
The utility model discloses an engine head gasket structure. The engine head gasket structure comprises a gasket body and is characterized in that cylinder holes are distributed in the gasket body, a convex rib is arranged on each cylinder hole and formed by a flange, positioning holes are distributed in the circumference of each cylinder hole and comprise the kidney-shaped positioning holes and the round positioning holes, and installation holes are formed outside the positioning holes; a hollow frame-shaped fixed end is arranged at one end of the gasket body, installation holes and threaded holes are distributed in the outer edge of the frame-shaped fixed end, and the upper end face and the lower end face of the gasket body are respectively coated with a black fluoro rubber layer. The engine head gasket structure is reasonable in structural design; due to the structure of the single-layer gasket body, the engine head gasket structure is convenient to machine and manufacture and low in manufacturing cost; due to the structure of the positioning holes, the engine head gasket structure is convenient to install and position; due to the convex rib structures on the cylinder holes and the structural design of the black fluoro rubber layers on the upper end face and the lower end face of the gasket body, the design is simple, seal performance of the engine head gasket structure is improved, and the service life of the engine head gasket structure is prolonged.
Description
Technical field
The utility model relates to cylinder seal technical field, relates in particular to a kind of cylinder mat structure.
