摘要

PURPOSE: A joint member of a pipe movement adjustment is provided to adapt to a temperature deviation according to an external impact or a weather change and to quickly and simply join pipes without a welding or a screw combination. CONSTITUTION: A pipe(10) has a first recessed groove(11) in the outer circumference of a jointed portion and a second recessed groove(12) between the end and the first recessed groove. A tightening member(20) has a hollow inside to penetrate a pipe. A clamping portion(21) is formed in the center and a spiral(22) and a protrusion are formed in the ends of the tightening member. A spring(30) is installed between the pipe and the tightening member. A spring holder(40) is a ring shape to be opened one side. A supporting piece to be inserted in the first recessed groove is integrally formed in the inner circumference of the spring holder. A packing(50) has a protrusion(51) to be stuck to the second recessed groove in the inner circumference. A tube joint(60) has a packing storage portion therein. A spiral is formed in the inner circumference of the tube joint to combine with the tightening member.
