Detailed Description

The utility model is further described below with reference to specific examples:

as shown in fig. 1-4: an external overflow piece comprises a pipe body 1, wherein the pipe body 1 comprises a water inlet and a water outlet, an elbow 11 is sleeved at the water inlet of the pipe body 1, a fixing ring 12 is screwed in the elbow 11, a positioning groove 10 convenient to clamp at an overflow port of a hand washing pool is arranged between the fixing ring 12 and the elbow 11, a ferrule 13 communicated with a sewer pipe is arranged at the water outlet of the pipe body 1, the elbow 11, the fixing ring 12 and the ferrule 13 are all communicated with the pipe body 1, a water outlet groove 131 is arranged on the inner side of the ferrule 13, the pipe body connected with the elbow is fixed at the overflow port of the hand washing pool through the elbow and the fixing ring, the lower end of the pipe body is communicated with the sewer pipe through the ferrule, and particularly, after the fixing ring is sleeved at the overflow port, the fixing ring is connected and fixed with the elbow.

In the external overflow device, the fixing ring 12 includes a threaded connection section 121 and a limiting ring 122, a sealing ring 123 is sleeved on the threaded connection section 121, one end of the threaded connection section 121 is integrally formed with the limiting ring 122, and the other end of the threaded connection section is connected with the elbow 11.

In the external overflow part, the elbow 11 is provided with a convex ring 111, and the pipe body 1 is provided with a groove 112 adapted to the convex ring 111, so as to facilitate the connection between the pipe body and the elbow.
