Description

Technical Field

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

[0002] The sealing ring, also known as the O-ring, is a fitting used for sealing, commonly used for dynamic sealing between the shaft and the hole, mainly playing the role of preventing liquid or gas leakage. After being compressed, the sealing ring can closely fit with the corresponding sealing surface through its own deformation to improve the sealing effect.

[0003] Chinese Patent Authorization Publication No. CN 206582244 U discloses an automobile sealing ring, including an automobile sealing ring. An anti-detachment groove for the automobile sealing ring is provided at the edge position of the automobile sealing ring. A sealing groove for the automobile sealing ring is provided on the upper surface of the automobile sealing ring near the inner side of the anti-detachment groove for the automobile sealing ring. And a folded rubber sleeve for the automobile sealing ring is provided on the upper surface of the automobile sealing ring near the inner side of the sealing groove for the automobile sealing ring. A penetrating disassembly hole for the folded rubber sleeve of the automobile sealing ring is provided on the outer wall of the folded rubber sleeve of the automobile sealing ring. In the utility model, the four anti-detachment grooves for the automobile sealing ring are sequentially placed below the four protrusions on the dust cover, so that the anti-detachment grooves for the automobile sealing ring are engaged with the protrusions on the dust cover, thereby preventing the automobile sealing ring from falling off the dust cover during use. The above-mentioned existing technical solutions have the following deficiencies: The sealing ring is usually simply made of a rubber ring, so its own strength and anti-deformation ability are poor. When the sealing ring is used for a long time or is subjected to a strong impact, it is easy to break and deform, and there is a certain room for optimization. Therefore, an anti-cracking automobile sealing ring can be proposed to solve the above problems. Content of the Utility Model

[0011] Preferably, the sizes of the guide blocks match the sizes of the guide grooves, and the guide blocks and the guide grooves are symmetrically arranged about the central axis of the movable block.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] When the main body of the automobile sealing ring is affected by external factors such as bumps, squeezes, and collision forces during use, the movable column will be forced to move downward, and then drive the movable block to move downward in the receiving groove. The movable block drives the elastic support plate to contract inward, thereby being able to play a protective role for the lower sealing ring, preventing the lower sealing ring from cracking and being damaged under the action of external extrusion and other forces, improving the anti-cracking effect on the lower sealing ring, extending the service life of the lower sealing ring, and the sliding of the guide block in the guide groove can play a role in limiting and guiding the movable block;

[0014] The sliding of the guide block in the guide groove can play a role in limiting and guiding the movable block, avoiding the deviation of the movable block during movement, and improving the stability of the movable block during movement;

[0015] By setting the protection mechanism, by setting the waterproof layer, which is made of acrylic waterproof paint, it can play a very good role in waterproofing, anti-seepage, and protection. By setting the anti-corrosion layer, which is made of epoxy resin paint, it can play a very good anti-corrosion effect. By setting the wear-resistant layer, which is made of polyurethane wear-resistant paint and has characteristics such as wear resistance and chemical corrosion resistance, it can play a very good wear-resistant effect, preventing the installation surface from being worn and scratched;

[0016] By setting the first compensation ring and the first compensation groove, during use, the compensation function at the connection between the outer side of the lower sealing ring and the upper sealing ring can be realized through the action of the first compensation ring and the first compensation groove, effectively improving the sealing effect.

[0017] By setting the second compensation ring and the second compensation groove, during use, the compensation function at the connection between the inner sides of the upper sealing ring and the lower sealing ring can be realized through the action of the second compensation ring and the second compensation groove, thereby effectively improving its sealing property.
