[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, the high-strength rubber sealing ring comprises a sealing ring body 1 arranged in an annular structure, a sealing component for improving sealing strength and movable up and down is arranged on the corresponding end surface of the sealing ring body 1, two limiting rings 2 for movable limiting of the sealing component are arranged on the sealing ring body 1, a connecting ring groove 3 for installing the sealing component is opened on the corresponding end surface of the sealing ring body 1, the sealing component comprises a sealing ring 4 for improving sealing strength and movably connected to the sealing ring body 1, a sealing frame 5 located inside the sealing ring 4, and two magnetically repelling magnetic rings 6, and the cross section of the sealing ring 4 is arranged in a T-shaped structure , two limit rings 2 are respectively located on both sides of the sealing ring 4 and fixedly connected to the end face of the sealing ring body 1. A connecting skeleton 7 for improving the strength of the sealing ring body 1 is embedded in the connecting ring groove 3. Two magnetic rings 6 are relatively arranged in the connecting ring groove 3. The structure is simple, and the sealing strength of the sealing ring body 1 is effectively improved by the cooperation of the sealing ring 4, the connecting ring groove 3, the magnetic ring 6 and the limit ring 2 structure, and a multi-layer sealing effect is obtained. At the same time, the sealing ring 4 and the limit ring 2 are respectively made of fluororubber material and fluororubber, which can make them have high elasticity and oil resistance and corrosion resistance, and greatly extend the service life of the sealing ring.

[0021] To further elaborate, in order to improve the compressive strength of the sealing ring body 1 and the sealing ring 4 and facilitate the movement of the sealing ring 4, the connecting skeleton 7 is embedded in the bottom of the connecting ring groove 3 in a concave structure, and the two magnetic rings 6 are installed inside the connecting skeleton 7 in a repelling structure.

[0022] To further elaborate, in order to achieve the movable limit of the sealing ring 4, the two limit rings 2 are respectively located on both sides of the notch of the connecting ring groove 3, and cooperate to form a limit shrinkage for the movable limit of the sealing ring 4.

[0023] To further elaborate, in order to improve the compressive strength of the sealing ring body 1 and the sealing ring 4, the sealing skeleton 5 has a T-shaped cross-section and is located inside the sealing ring 4 for support. The sealing skeleton 5 and the connecting skeleton 7 are both woven from stainless steel wires.

[0024] To elaborate further, in order to increase the service life of the sealing ring body 1, the sealing ring body 1 is made of nitrile rubber material, the sealing ring 4 is made of fluororubber material, and the limiting ring 2 is made of fluororubber. Fluororubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain, so that the sealing ring 4 has high elasticity to open the sealing ring body 1 to achieve a high-strength sealing effect, and at the same time has certain sealing performance itself. The limiting ring 2 uses fluororubber to make it have high oil and high temperature resistance, which can effectively prevent oil corrosion and aging from causing oil leakage and extend its service life.

[0025] The limiting ring 2 and the sealing ring body 1 are integrally formed.

[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0027] Although the terms such as sealing ring body 1, limiting ring 2, connecting ring groove 3, sealing ring 4, sealing frame 5, magnetic ring 6, connecting frame 7 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
