PIPE JOINT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a pipe joint structure easily and promptly conducting a connecting work and surely connecting pipes without thread cutting work. SOLUTION: This pipe joint structure comprises a joint body 1 wherein a part of an inner peripheral surface 5 of an insertion hole 4 to which a connected pipe 2 is inserted becomes a cam surface 6, and a plurality of small disk elements 3... arranged between an outer peripheral surface 13 of the connected pipe 2 inserted in the insertion hole 4 and the cam surface 6 of the joint body 1. The small disk elements 3 have a circular outer peripheral end edge 16 pressed by the cam surface 6 to sharply bite in the outer peripheral surface 13. The circular outer peripheral end edge 16 bites into the outer peripheral surface 13, thereby preventing the connected pipe 2 from coming off.
