CONNECTING STRUCTURE FOR MULTIPLE TRAP

摘要

PURPOSE: A coupling structure of a drain trap is provided to facilitate the installation of a drain trap in a water-use place or facility and to prevent a water leakage through firm sealing of joints. CONSTITUTION: A coupling structure of a drain trap comprises a drain pipe(100), a discharge pipe(300), and a connection pipe(200). The drain pipe is buried in a wall or floor. The discharge pipe is inserted and coupled to the drain pipe. The connection pipe connects the drain pipe and the discharge pipe, and the connection pipe includes a grab ring for fixing the discharge pipe inserted from the back and a ring-shaped grab ring support which is thread-coupled into the connection pipe and supports the grab ring.
