[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] The utility model provides Figures 1 to 4 The stress-resistant rubber gasket shown includes a gasket body 1 made of rubber and in a circular ring shape. Anti-slip strips 11 are integrally formed on both the upper and lower surfaces of the gasket body 1. Multiple anti-slip strips 11 are provided and evenly distributed around the axis of the gasket body 1. The provision of anti-slip strips 11 improves the anti-slip performance of the gasket body 1.
[0024] Rounded corners 12 are provided at both upper and lower ends of the outer ring of the gasket body 1. The rounded corners 12 are provided to facilitate the installation of the rubber gasket and avoid scratching the operator.
[0025] The outer ring of the gasket body 1 is defined by a first annular groove 2, located midway along the height of the gasket body 1. A first airbag ring 3, made of rubber, is secured within the first annular groove 2. A first arcuate groove 6 is defined on the inner wall of the first annular groove 2, forming a first accommodating cavity 7 between the first arcuate groove 6 and the first airbag ring 3. When the gasket body 1 is deformed by external forces, the first airbag ring 3 provides a certain amount of space for contraction. This also absorbs some of the deformation force, reducing the compressive strain of the gasket body 1 and improving the stress resistance of the rubber gasket's outer ring.
[0026] When the first airbag ring 3 is squeezed, the first accommodating cavity 7 will provide deformation space for the first airbag ring 3, so that the first airbag ring 3 will fill into the first accommodating cavity 7 when squeezed; at the same time, when the first airbag ring 3 extends outward from the first annular groove 2, the sealing performance of the outer ring of the rubber gasket is improved.
[0027] The inner ring of the gasket body 1 is defined by a second annular groove 4, into which a second airbag ring 5 is secured. The second airbag ring 5 is made of rubber. A second arc groove 8 is defined on the inner wall of the second annular groove 4, forming a second accommodating cavity 9 between the second arc groove 8 and the second airbag ring 5. When the gasket body 1 is deformed by external forces, the second airbag ring 5 provides a certain amount of space for contraction. It also absorbs some of the deformation force, reducing the compressive strain of the gasket body 1 and improving the stress resistance of the rubber gasket's outer ring.
[0028] When the second airbag ring 5 is squeezed, the second accommodating cavity 9 will provide deformation space for the second airbag ring 5, so that the second airbag ring 5 will fill into the second accommodating cavity 9 when squeezed; at the same time, when the second airbag ring 5 extends outward from the second annular groove 4, the sealing performance of the inner ring of the rubber gasket is improved.
[0029] The second annular groove 4 is distributed correspondingly to the first annular groove 2 , so that the inner and outer rings of the gasket body 1 can be protected at the same time, thereby improving the stress damage resistance of the overall structure of the rubber gasket.
[0030] A contraction groove 10 is formed on the inner wall of the first arc groove 6 and extends through the inner wall of the second arc groove 8. The first accommodating chamber 7 and the second accommodating chamber 9 are connected via the contraction groove 10. A plurality of contraction grooves 10 are provided and are evenly distributed around the axis of the gasket body 1. The contraction grooves 10 are provided to provide a certain amount of contraction space when the gasket body 1 is deformed by external pressure.
[0031] The inner diameter of the shrinkage groove 10 gradually decreases from the first accommodating chamber 7 toward the second accommodating chamber 9. The inner diameters at both ends of the shrinkage groove 10 are set differently, which can ensure the connection strength of the gasket body 1 at this location while providing a certain shrinkage space.
