[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution: a high-elasticity, oil-resistant rubber sealing ring, including a sealing body 1, an outer ring 2 fixedly connected to the outer side of the sealing body 1, and an inner ring 3 fixedly connected to the inner side of the sealing body 1. The sealing body 1 serves as the main sealing structure, with its outer ring 2 and inner ring 3 respectively in close contact with the surfaces of corresponding components to achieve a preliminary sealing function. An elastic component 4 plays a crucial role in elastic compensation and enhancing sealing performance within the sealing ring. The ring also includes an elastic component 4, the outer side of which is fixedly connected to the inner wall of the sealing body 1. The elastic component 4 encloses... The sealing body 1 includes a rubber sleeve 41, an annular block 42 fixedly connected to the inner side of the rubber sleeve 41, a reinforcing ring 45 fixedly connected to the inner side of the annular block 42, a helical spring 43 fixedly connected to the outer side of the annular block 42, and a helical plate 44 fixedly connected to the outer side of the helical spring 43. Elastic components 4 are symmetrically arranged along both sides of the sealing body 1. The outer side of the rubber sleeve 41 is fixedly connected to the inner wall of the sealing body 1. A threaded groove 46 is formed in the wall of the reinforcing ring 45. When subjected to force, the reinforcing ring 45 can absorb and release some energy through the deformation of the threaded groove 46, thereby adjusting the rigidity and elasticity of the reinforcing ring 45. When the pressure is low, the deformation of the threaded groove 46 is small, and the reinforcing ring 45 provides relatively large rigidity support, ensuring the shape stability of the sealing ring. When the pressure is high, the threaded groove 46 will deform to a greater extent, reducing the rigidity of the reinforcing ring 45 and increasing its elasticity, to better adapt to external pressure and prevent the sealing ring from being damaged due to excessive rigidity.
[0023] The spiral plate 44 is fixedly connected to the outer wall of the annular block 42 on both sides. The annular block 42 is arranged in a ring along the inner side of the rubber sleeve 41. The annular block 42, the spiral spring 43, and the spiral plate 44 are all located between the rubber sleeve 41 and the reinforcing ring 45. The spiral spring 43 and the spiral plate 44 are arranged in a ring along the inner side of the rubber sleeve 41. When the sealing ring is subjected to external pressure or deformation, the rubber sleeve 41 can deform to a certain extent to adapt to external changes due to its own elastic properties. At the same time, the spiral spring 43 on the outer side of the annular block 42 will undergo compression deformation due to its inherent elasticity, effectively absorbing the pressure energy applied by the outside, thereby buffering the impact force on the sealing ring and preventing the sealing ring from being damaged due to excessive pressure. The spiral plate 44 assists the spiral spring 43 in transmitting and dispersing force. The spiral groove 46 arranged in a spiral shape on the outer wall of the reinforcing ring 45 can change the elastic modulus of the reinforcing ring 45 to a certain extent.
[0024] In use, the sealing body 1 serves as the main sealing structure, with its outer ring 2 and inner ring 3 making close contact with the surfaces of the corresponding components to achieve a preliminary sealing function. The elastic component 4 plays a crucial role in elastic compensation and enhancing sealing performance within the sealing ring.
[0025] When the sealing ring is subjected to external pressure or deformation, the rubber sleeve 41 can deform to a certain extent to adapt to external changes due to its own elastic properties. At the same time, the helical spring 43 on the outside of the annular block 42 will undergo compression deformation due to its inherent elasticity, effectively absorbing the pressure energy applied by the outside, thereby buffering the impact force on the sealing ring and preventing the sealing ring from being damaged due to excessive pressure. The spiral plate 44 assists the helical spring 43 in transmitting and dispersing force. The spiral groove 46 on the outer wall of the reinforcing ring 45 can change the elastic modulus of the reinforcing ring 45 to a certain extent.
[0026] Specifically, when under stress, the reinforcing ring 45 can absorb and release some energy through the deformation of the threaded groove 46, thereby adjusting the rigidity and elasticity of the reinforcing ring 45. When the pressure is low, the deformation of the threaded groove 46 is small, and the reinforcing ring 45 provides relatively large rigid support to ensure the shape stability of the sealing ring; when the pressure is high, the threaded groove 46 will deform to a greater extent, reducing the rigidity of the reinforcing ring 45 and increasing its elasticity, so as to better adapt to external pressure and avoid damage to the sealing ring due to excessive rigidity.
