Description

Technical Field

[0001] The utility model relates to the technical field of rubber rings, in particular to a rubber ring which is easy to assemble and disassemble. Background Art

[0002] The rubber sealing ring is an annular cover composed of one or more parts, which is fixed on a ring or washer of the bearing and contacts with the other ring or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects.

[0003] The China Patent Network discloses a rubber ring for tap water pipes that is easy to disassemble and assemble, with the publication number CN212775540U. Although the design is novel, easy to operate and has good use effect, it can facilitate the rapid installation and removal of the rubber ring, thereby improving work efficiency, and effectively sealing the tap water pipe to prevent water leakage in the tap water pipe and improve the sealing performance. However, since the tightening rack ring in the patent is arranged on the outside of the rubber ring, frequent disassembly and installation can easily cause wear to the rubber ring, thereby affecting the service life of the rubber ring. Moreover, it can be seen from the figure of the comparative document that the thickness of the tightening rack ring is greater than the thickness of the rubber ring, which results in the rubber ring not being able to fully contact the tap water pipe, seriously affecting the sealing performance of the tap water pipe.

[0004] For this reason, a rubber ring that is easy to disassemble and assemble is proposed. Utility Model Content
