Title:
PIPE JOINT MEMBER
Document Type and Number:
WIPO Patent Application WO/2024/101142
Kind Code:
A1
Abstract:
[Problem] To provide a pipe joint member with which an operator can more reliably recognize that fluid pressure is being applied to the pipe joint member when an attempt was made to connect a corresponding pipe joint member while fluid pressure was applied to the pipe joint member. [Solution] A female pipe joint member 10 is removably connected to a corresponding male pipe joint member 1. When the female pipe joint member 10 receives fluid pressure from the rear-end opening 14 with the male pipe joint member 1 in a disconnected state, a second slide member 26 is displaced to the forward position, and a first lock 78 is held in a displacement-preventing position by the second slide member 26. This prevents a first slide member 24 from being displaced from a forward position to a rearward position. If an attempt is made to insert the male pipe joint member 1 into an internal space 16 of the female pipe joint member 10, a front end surface 2 of the male pipe joint member 1 engages with the first slide member 24 and the male pipe joint member 1 cannot be inserted to a predetermined position where connection will be completed.
