DETAILED DESCRIPTION

[0020] In order to better illustrate the content of the utility model, the following will be expanded and described in combination with the drawings and the embodiment:

[0021] There are Figures 1-2 As shown, the utility model discloses a bidirectional rubber sealing ring convenient to replace and maintain, including connecting ring 1 and the outer ring 7 of setting in the connecting ring 1 outside, the both sides screw thread connection of the connecting ring 1 have splicing ring 6, the outer side surface of splicing ring 6 and the connecting ring 1 form matching groove 11, the matching groove 11 is provided with elastic ring 12, the outer side of elastic ring 12 is provided with the rubber ring 10 of installing with matching groove 11, the outer side surface of rubber ring 10 is provided with a plurality of convex rings 9.

[0022] Further, the first limiting ring 2 is arranged in the ring side surface of the connecting ring 1 close to the outer ring 7, and the second limiting ring 3 is arranged in the two side planes of the connecting ring 1.

[0023] Further, the first matching ring part 8 capable of being clamped into the first limiting ring 2 is arranged on the rubber ring 10.

[0024] Further, the rubber ring 10 is further provided with a second matching ring part 13 capable of being clamped into the second limiting ring 3.
