Abstract
The utility model relates to a sealing gasket, and particularly relates to a sealing gasket structure specially used for a cylinder cover. The sealing gasket for a cylinder cover comprises a sealing gasket body and a boss disposed at the front part of the body, the sealing gasket is characterized in that, the front end part of the boss is provided with a coronary sealing box, the surface of the coronary sealing box is provided with several sealing projections, the connecting part of the coronary sealing box and the boss is provided with an oil discharge groove, and the rear part of the body is provided with several sealing convex points. The sealing gasket in the utility model is advantaged by good sealing effect, simple structure, convenient use, long service lifetime, etc.
Description
Technical field
The utility model relates to a kind of sealing gasket, especially relates to a kind of gasket structure that is exclusively used in cylinder head.
Background technique
As everyone knows, the cylinder head gasket conventional type of using at present all be about surface of contact add the salient line mode and design.But the performance parameter in the entire engine design now improves constantly, and makes the design service life of its product and sealability require also just to increase.So original product specification structure is difficult to satisfy the integral body requirement and the technical order of existing designed engines.Make its sealing effect and working life not long, occur phenomenons such as leakage of oil through regular meeting, also can violate environmental regulations.
Summary of the invention
The utility model mainly is at the above-mentioned technical problem of existing in prior technology, and the cylinder head gasket of a kind of good sealing effect, simple in structure, easy to use, long service life is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cylinder head gasket, comprise sealing gasket body and the boss that is positioned at body portion, it is characterized in that described boss front end is provided with crown sealing block, described crown sealing block surface is provided with the several sealed projection, described crown sealing block and boss joint are provided with unloads oil groove, and described rear body is provided with the several sealed salient point.The utility model corrects at the problem that exists in the existing cylinder cover sealing configuration shape.This structure is from mechanics, and the sealing gasket line sample distribution of new structure form is reasonably designed in the scientific research of plasticity aspect.Thereby improve the sealing effect of countercylinder housing.Avoid occurring oil leakage phenomenon, improve its working life simultaneously, reduce pollution environment.In order to realize the sealing effect, at sealing gasket and cylinder cover mould is installed and is contacted the bottom, be provided with the crown sealing block in triangle " individual " font cross section.Crown sealing block front surface has formed the seal convexity of three places trigonometric forms combination, and bottom faces, the side of itself and cylinder cover mounting groove are sealed simultaneously.Its spur line is that suitable magnitude of interference cooperates with cylinder cover groove.Being that trigonometric form branch is local is of a size of the interference fit design with mounting groove, guarantees airtight quality.
As preferably, described seal convexity is four, and seal convexity is distributed on crown sealing block front surface.Two seal convexities in side are the main structure guarantee that presents better sealing effect in the design.
As preferably, described several sealed salient point is four, and described sealing salient point is symmetrically distributed in rear body.Can increase the pressure of interference fit in the time of in the mounting groove, thereby reach better sealing, simple in structure, reasonable in design.
As preferably, the described oil groove that unloads is " V " font.The joint of crown sealing block and boss both sides forms " V " individual groove, makes its formation unload oil groove, thereby plays the pressure that reduces oil, prolongs the working life of sealing gasket.
As preferably, described sealing gasket body, boss, crown sealing block, seal convexity, sealing salient point are integrally manufactured.
Therefore, the utlity model has characteristics such as good sealing effect, simple in structure, easy to use, long service life.
Description of drawings
Accompanying drawing 1 is that a kind of structure of the present utility model is cutd open figure.
Accompanying drawing 2 is the local enlarged diagrams at A position in the accompanying drawing 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1,2, a kind of cylinder head gasket, the boss 2 that comprises sealing gasket body 1 and be positioned at body portion, boss front end are provided with crown sealing block 3, crown sealing block surface is provided with three seal convexities 4, and seal convexity is distributed on crown sealing block front surface.Crown sealing block and boss joint are provided with unloads oil groove 5, unloads oil groove and is " V " font.Rear body is provided with four sealing salient points 6.The sealing salient point is symmetrically distributed in rear body.Sealing gasket body, boss, crown sealing block, seal convexity, sealing salient point are integrally manufactured.
In order to realize the sealing effect, at sealing gasket and cylinder cover mould is installed and is contacted the bottom, be provided with the crown sealing block in triangle " individual " font cross section.Crown sealing block front surface has formed the seal convexity of three places trigonometric forms combination, and bottom faces, the side of itself and cylinder cover mounting groove are sealed simultaneously.Its spur line is that suitable magnitude of interference cooperates with cylinder cover groove.Being that trigonometric form branch is local is of a size of the interference fit design with mounting groove, guarantees airtight quality.Two seal convexities in side are the main structure guarantee that presents better sealing effect in the design.Acting as of sealing salient point: can increase the pressure of interference fit in the time of in the mounting groove, thereby reach better sealing, simple in structure, reasonable in design.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
