Fig. 2 is a schematic cross-sectional view of the gasket for an engine.
In the figure, 1, a body; 2. a cylinder groove; 3. a front seal lip; 4. a middle sealing lip; 5. a rear seal lip; 6. a seal abutment; 7. an arc-shaped groove; 8. sealing point A; 9. and sealing the contact.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1 and 2, the sealing gasket for the engine comprises a body 1 which is in sealing connection with a cylinder cover, wherein the body 1 is of a circular structure, a cylinder groove 2 is formed in the middle of the sealing gasket, a sealing structure is arranged on the end face of the body 1 which is in sealing connection with the cylinder cover, the sealing structure is connected to the body 1 in a bonding mode, the sealing structure comprises a front section sealing lip 3, a middle section sealing lip 4 and a rear section sealing lip 5 which are sequentially distributed from left to right, the front section sealing lip 3, the middle section sealing lip 4 and the rear section sealing lip 5 are integrally arranged, the longitudinal section of the middle section sealing lip 4 is obliquely arranged, a sealing abutting part 6 is formed between the inner end of the middle section sealing lip 4 and the rear section sealing lip 5, an arc-shaped groove 7 is formed between the outer end of the middle section sealing lip 4 and the front section sealing lip 3, and the top end of the front section sealing lip 3 is provided with a sealing point A8 which is formed by abutting against the cylinder cover.
Preferably, the bottom end of the front sealing lip 3 has a sealing contact 9 protruding outwards and abutting against the body 1.
Preferably, the body 1 is made of rubber material.
The sealing gasket is placed at the corresponding position of the cylinder cover (the bottom of the cylinder cover is provided with the sealing groove), the cylinder cover is then mounted on the cylinder body, the sealing gasket is stressed to deform in the process, the groove wall of the sealing groove in the cylinder cover presses the front section sealing lip 3, the front section sealing lip 3 is easier to deform under the action of the arc-shaped groove 7, the sealing contact 9 is further contacted with the body 1, and the sealing contact between the point and the surface is formed, so that the sealing performance is improved.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
Although the terms of the body 1, the cylinder groove 2, the front stage seal lip 3, the middle stage seal lip 4, the rear stage seal lip 5, the seal abutment 6, the arc-shaped groove 78, the sealing point A8, the seal contact 9, and the like are used more herein, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
