[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-4The utility model provides an embodiment: a reinforced composite sealing rubber ring, comprising a rubber sealing ring 1, a groove 3 is provided at the inner center of the rubber sealing ring 1, and a reinforcing layer 2 is provided at the inner wall center of the groove 3. The reinforcing layer 2 made of fiber is used to avoid damage and wear of the rubber sealing ring 1, thereby improving the strength and wear resistance of the rubber sealing ring 1. The outer wall of the rubber sealing ring 1 is laterally arranged with three fixing rings 4. The fixing ring 4 made of fluororubber is provided to enable it to have high temperature resistance and chemical corrosion resistance. It can also be reasonably pre-tightened to ensure that the sealing ring generates appropriate contact stress within the normal working range, thereby improving the sealing effect. A plurality of first microcapsules 5 are provided at the inner center of the three fixing rings 4, and a plurality of second microcapsules 6 are provided at the inner center of the rubber sealing ring 1. Through the provision of the first microcapsules 5 and the second microcapsules 6, when the rubber sealing ring 1 and the fixing ring 4 are damaged and worn after being used for a period of time, the damaged parts are filled and automatically repaired, thereby improving the service life.

[0031] The first microcapsule 5 includes a shell 501, a filler 502 and a repair agent 503. The shell 501 is arranged at the upper center of the fixing ring 4, the filler 502 is arranged at the center of the shell 501, and the repair agent 503 is arranged at the center of the filler 502. When the microshell 501 is subjected to external stimulation or damage, the filler 502 will release the repair agent 503 for repair, thereby extending the service life of the microcapsule and protecting the functional components therein from damage. The shell 501 is made of polyurethane. The shell 501 made of polyurethane improves the pressure resistance of the first microcapsule 5 and the second microcapsule 6, thereby avoiding the first microcapsule 5 and the second microcapsule 6 from being broken during squeezing.

[0032] The groove 3 is trapezoidal in shape, and one end of the groove 3 passes through the inner wall of the rubber sealing ring 1 and reaches the rubber sealing ring 1. The design of the trapezoidal groove 3 can increase the contact area, thereby improving the sealing effect. The material of the reinforcing layer 2 is fiber. The reinforcing layer 2 made of fiber can avoid damage and wear of the rubber sealing ring 1, thereby improving the strength and wear resistance of the rubber sealing ring 1. The material of the fixing ring 4 is fluororubber. The setting of the fixing ring 4 made of fluororubber can make it have high temperature resistance and chemical corrosion resistance. The reinforcing layer 2 and the rubber sealing ring 1 are sleeved and connected. The sleeved connection between the reinforcing layer 2 and the rubber sealing ring 1 makes it convenient to load and unload, thereby improving convenience.

[0033] Working principle: When the reinforced composite sealing rubber ring is used, the elasticity of the rubber sealing ring 1 is first used to set the reinforcement layer 2 into the groove 3, and then the fixing ring 4 made of fluororubber is set to make it have the performance of high temperature resistance and chemical corrosion resistance, and it can also be reasonably pre-tightened to ensure that the sealing ring generates appropriate contact stress within the normal working range, thereby improving the sealing effect, and then the reinforcement layer 2 made of fiber is used to avoid damage and wear of the rubber sealing ring 1, thereby improving the strength and wear resistance of the rubber sealing ring 1.

[0034] When the reinforced composite sealing rubber ring is damaged after being used for a period of time, when the micro-shell 501 is subjected to external stimulation or damage, the filler 502 will release the repair agent 503 for repair, thereby extending the service life of the microcapsule and protecting the functional components therein from damage. Then, through the shell 501 made of polyurethane, the pressure resistance of the first microcapsule 5 and the second microcapsule 6 is improved, and the rupture of the first microcapsule 5 and the second microcapsule 6 during squeezing is avoided. Finally, through the setting of the first microcapsule 5 and the second microcapsule 6, when the rubber sealing ring 1 and the fixing ring 4 are damaged and worn after being used for a period of time, the damaged parts are filled and automatically repaired, thereby extending the service life.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
