Abstract
A plug structure of a liquid drainage installation includes a sealing ring clamped between two combined half bodies. The outer periphery of the sealing ring protrudes outward from the outer periphery of the two half bodies. Thus, the protruding dimension of the sealing ring may be adjusted by the clamping extent of the two bodies, thereby compensating the wearing amount due to usage. The two half bodies may be separated easily, thereby facilitating replacing the sealing ring.
