[0023] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model relates to a high-pressure resistant rubber sealing gasket with a self-lubricating coating, comprising a rubber gasket body 1, a lubricating rubber outer ring 2 fixedly connected to the outer side of the rubber gasket body 1, and the outer contour of the lubricating rubber outer ring 2 having an arched structure, and a lubricating rubber inner ring 3 fixedly connected to the inner side of the rubber gasket body 1. Both the lubricating rubber outer ring 2 and the lubricating rubber inner ring 3 are made of polytetrafluoroethylene material, which can achieve the effects of high pressure resistance and self-lubrication. An upper lubricating layer 4 is fixedly connected to the top of the rubber gasket body 1, and a lower lubricating layer 5 is fixedly connected to the bottom of the rubber gasket body 1. The upper lubricating layer 4 and the lower lubricating layer 5 have the same thickness, and both the upper lubricating layer 4 and the lower lubricating layer 5 are made of oil-impregnated silicone, achieving self-lubrication through the oil contained inside the silicone.
