[0003] During the use of the existing sealing ring with a positioning structure, in order to ensure the sealing performance, the parts are pressed tightly against the sealing rubber ring. Long-term exposure to pressure exceeding the compressive capacity will cause the rubber to harden and age faster, lose elasticity and sealing performance, and shorten the service life. Therefore, technical personnel in this field provide a sealing rubber ring with a positioning structure to solve the problems raised in the above background technology. Utility Model Content

[0010] The above technical solution makes it convenient to limit the limit block.

[0011] Furthermore, the pillar and the two limit blocks are made of rubber;

[0012] The above technical solution facilitates cooperation with a rubber base, and the rubber is soft, making it easy to insert the two limit blocks into the storage tank.
