PIPE JOINT
Document Type and Number:
Japanese Patent JP2014196801
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To connect a pipe body with a one-touch operation by reliably preventing detachment of the pipe body.SOLUTION: An insertion guide 4 is forcedly fitted and inserted in an inner cylinder part 23 of a joint body 2 with a flange 41 as a tip to cover a seal S, and an outer cylinder member 3 is screwed with one side male screw 22, so that a pipe joint 1 is assembled. Then, the pipe body 10 is inserted between the inner cylinder part 23 and the outer cylinder member 4 of the joint body 2, so that detachment of the pipe body 10 is prevented and the pipe body can be connected to the pipe joint 1. That is to say, when the pipe body 10 exceeds a detachment prevention part 43 of the insertion guide 4, if the pipe body 10 is drawn, the detachment prevention part 42 bites into an inner periphery of the pipe body 10 so as to cope with drawing. Also, when the insertion guide is pushed into a setting position via the pipe body 10, its rear edge is locked with a projection 26 of the inner cylinder part so as to block the insertion guide 4 from moving backward.
