The socket 4 comprises a main body 1 and a rotating sleeve 2.
In a pipe joint including and,
Is formed, and substantially rectangular guide ribs 13 are arranged side by side in the circumferential direction on the end surface of the collar 9, and the guide ribs 13 serve as insertion gaps 14, and the base portion of the insertion gap 14 has a leaf spring end locking portion. 12 is provided to form the main body 1, and the leaf spring 10 and the cam engaging projections 11 are integrally provided continuously in the axial direction at a plurality of circumferential positions inside the cylinder to form the rotary sleeve 2. Is formed at a plurality of positions near the connection end of the triangular columnar locking cam 7 having a taper in the axial direction, and a fitting gap 15 into which the cam engaging projection 11 fits is sandwiched between the locking cams 7 and the main body 1 is provided behind it. Guide rib 1
An insertion rib 8 to be inserted between the three is formed, and a collar 9 is provided behind it.
To form the plug 5, and the end of the leaf spring 10 of the rotary sleeve 2 is locked to the leaf spring end locking portion 12 of the main body 1,
While the rotary sleeve 2 is locked to the main body 1, the insertion rib 8 of the plug 5 is inserted between the guide ribs 13 of the main body 1, and at the same time, the locking cam 7 is brought into contact with the cam engaging projection 11 of the rotary sleeve 2, The rotation sleeve 2 is rotated by deforming the leaf spring 10 in the rotation direction until the locking cam 7 reaches a position where the engagement projection 11 is pushed away, and the engagement protrusion is generated by the repulsive force of the leaf spring 10 deformed in the rotation direction. 11 is the fitting gap 1
5 is pushed back to engage with the locking cam 7, and the plug 5
And a socket 4 for connecting the pipe joint.

を接続することを特徴とする配管継ぎ手。2. A cylindrical socket 4 and a cylindrical plug 5
The socket 4 comprises a main body 1 and a rotating sleeve 2.
In the pipe joint including the sleeve retaining ring 3 and the sleeve retaining ring 3, a flange 9 is formed at the tip end of the cylinder 6, and a substantially rectangular guide rib 13 is arranged side by side in the circumferential direction on the end surface of the flange 9. A space is defined as an insertion gap 14, and a leaf spring end engaging portion 12 is provided at the base of the insertion gap 14 to form the main body 1.
The leaf spring 10 and the cam engaging projections 11 are integrally provided in the circumferential direction in the cylinder in a continuous manner in the axial direction to form the rotary sleeve 2, and the rotary sleeve 2 is formed at a plurality of locations near the connecting end of the cylinder 6. Inserting ribs that form a triangular-cylindrical locking cam 7 that has a taper in the direction, and are inserted between the guide ribs 13 of the main body 1 behind the engaging gap 15 into which the cam engaging projection 11 is fitted. 8 is formed, and a flange 9 is formed behind it to form a plug 5, and the end portion of the leaf spring 10 of the rotary sleeve 2 is locked to the leaf spring end locking portion 12 of the main body 1 to form the rotary sleeve 2 The body 1
With the sleeve retaining ring 3 arranged at the end of the rotary sleeve 2, the insertion rib 8 of the plug 5 is inserted between the guide ribs 13 of the main body 1 and at the same time the locking cam 7 is attached to the rotary sleeve 2. While contacting the cam engaging projection 11 of FIG. 1, the rotary sleeve 2 is rotated by deforming the leaf spring 10 in the rotational direction until the locking cam 7 reaches a position where the engaging projection 11 is pushed away. A pipe joint in which the engaging projection 11 is pushed back to the position of the fitting gap 15 by the repulsive force of the leaf spring 10 and fits with the locking cam 7 to connect the plug 5 and the socket 4.
