[0003] During use of the above invention, first, the two sets of positioning rods are pulled to drive the springs to elastically expand and contract in the two sets of sleeves. At this time, the sleeve can be inserted into the inner side of the sealing ring for connection and assembly. Then the sleeve is moved to the specified position. At this time, the positioning rods can be loosened to prompt the two sets of positioning rods to be inserted into the positioning holes under the elastic restoring force of the springs, thereby positioning the sleeve. However, the two positioning rods need to be pulled at the same time, which makes it inconvenient to free up hands to support the sealing ring so that the positioning rods and the positioning holes are aligned. In addition, it is necessary to operate the two fixings and the fixing holes to connect. The whole process is relatively cumbersome and not convenient for quick installation and disassembly.

[0004] For this reason, we propose an anti-oil leakage rubber sealing ring. Utility Model Content
