CONNECTION STRUCTURE OF CORRUGATE PIPE

摘要

PROBLEM TO BE SOLVED: To solve a problem of a joint enclosing and connecting end parts of corrugate pipes from the outside wherein the joint becomes slide resistance to require a large amount of labor when adjusting arrangement after the connection of the corrugate pipes, and to solve a problem of a means inserting the end parts of the corrugate pipes into a cylindrical joint body to connect the corrugate pipes wherein lock force of the corrugate pipes is weak to allow detachment when adjusting the arrangement. SOLUTION: A nearly cylindrical joint has external diameter nearly equal to internal diameter of the corrugate pipes to be connected and has lock protrusions on the outer wall. As the joint is inserted into the corrugate pipes, the lock protrusions lock intake holes of the corrugate pipes from the inside to connect both the corrugate pipes.
