STRUCTURE FOR CONNECTING A PIPE-CONNECTING LINK COUPLER

摘要

The present invention relates to a coupler connection structure for interconnecting pipes. Particularly, the coupler connection structure comprises a circular coupler link body segmented into three parts which connected via respective hinges. The circular coupler link body has a flange with a guide groove corresponding to a guide protrusion protruding from the flange, such that two flanges are coupled together in a firmer and safer manner, and such that a firmer and safer coupling can be visually recognized. The coupler connection structure of the present invention achieves improved water-tightness by a packing fitted between lap joint balancing portions of a lap joint.
