Description

Technical Field

[0001] The utility model relates to an anti-cracking automobile sealing ring, belonging to the technical field of automobile sealing rings. Background Art

[0002] Automobile sealing rings are components used for sealing in automobiles, and are mainly made of elastomers. Due to the large number of pipe connections and valves in automobiles, different sealing rings have specific uses, and the different environments in which they are located lead to different design requirements for sealing rings in different positions.

[0003] For example, CN216143160U discloses a crack-proof automobile sealing ring, which improves the structural strength of the sealing ring body by setting a reinforcement component, so that the sealing ring body is in close contact with the installation shell after installation, avoiding deformation of the sealing ring body after precooling or preheating, resulting in oil leakage and liquid leakage, and improving the stability during use. The first connecting plate and the second connecting plate are slidably connected by the cooperation of the second limiting rod, the first limiting rod and the elastic ring, and can be automatically adjusted when the sealing ring body is deformed. The elastic ring is sleeved on the first limiting rod and the second limiting rod, which is convenient for users to disassemble and replace, and convenient for users to use for a long time. However, if the first connecting plate, the second connecting plate, the first limiting block and other structures are set in the inner ring of the automobile sealing ring, if the sealing ring needs to transport a gas or liquid medium, a certain obstruction will be generated, affecting the passing efficiency of the medium of the sealing ring. At the same time, if the first connecting plate, the second connecting plate, the first limiting block and other structures are deformed when heated or precooled, these structures will also cause the sealing ring body to deform to a certain extent, thereby affecting the sealing effect of the sealing ring body.
