Sewer line connection device

Abstract

The invention discloses a sewer line connection device, including a drain base and a detachable drain flange connected to the drain base; said drain flange is provided with a placing groove body underneath the edge near the top, and the interior of said placing groove body is filled with a sealing member. The invention adopts structures such as detachably connected drain flange and the drain base, and sealing member is added between the drain flange and drain base, which can increase sealing performance of the drainer, avoiding occurrence of phenomena such as leakage in the process of use; and at the same time, the sealing member can also be replaced according to needs, which is more time-saving and labor-saving, and can effectively avoid water from overflowing from the sewer line.

1 . A sewer line connection device including a drain base ( 1 ) and a detachable drain flange ( 3 ) connected to the drain base ( 1 ); said drain flange ( 3 ) is provided with a placing groove body ( 4 ) underneath the edge near the top, and the interior of said placing groove body ( 4 ) is filled with a sealing member ( 2 ). 
     
     
         2 . The sewer line connection device of  claim 1  wherein the top of said drain flange ( 3 ) extends towards the edge to form a projection, the lower part of which is set in cylindrical structure, the first fixing hole ( 10 ) is set below the projection of said drain flange ( 3 ), and the second fixing hole ( 11 ) is set below said drain base ( 1 ); said first fixing hole ( 10 ) and second fixing hole ( 11 ) are connected together by means of flat head screw ( 5 ). 
     
     
         3 . The sewer line connection device of  claim 2  wherein a sealing down pipe ( 8 ) is provided in conjunction with the inner wall of the cylindrical structure at the lower part of said drain flange ( 3 ), a mating groove ( 9 ) is provided below said drain flange ( 3 ), and a drain adapter ( 6 ) is placed inside said mating groove ( 9 ). 
     
     
         4 . The sewer line connection device of  claim 3  wherein in said drain adapter ( 6 ) is connected with down pipe ( 7 ), and the top outer circumference of the down pipe ( 7 ) is bonded to the drain adaptor ( 6 ) via glue for draining the water out. 
     
     
         5 . The sewer line connection device of  claim 1  wherein said sealing member ( 2 ) is rubber sealing ring.
