Claims

[Scope of utility model registration request]

A shielding wall is provided in the middle of the cylindrical tube, one end of which is used as a connecting part to a compressed fluid supply source, and a connecting member is attached to the other end. Plug insertion/removal is carried out by loosely fitting the plug into several small tapered holes drilled in the cylinder wall in the axial direction so that a part of the small plug-locking ball protrudes into the cylindrical body. At the same time, the outer peripheral wall in the side direction of the connecting part is the deepest and widest from the installation position of the shielding wall.
A first annular groove in which several holes for forming compressed fluid passages are opened is provided at the bottom of the groove near the shielding wall, and a first annular groove is formed continuously from the first annular groove on the connecting part side. A second annular groove that is slightly shallower and narrower in width, and a second annular groove that is shallower than the second annular groove but more than twice as wide as the second annular groove on the side of the plug insertion/removal part that is continuous with the first annular groove and is twice as wide as the second annular groove. By providing third annular grooves each having several holes for forming compressed fluid passages at the bottom of the groove near the shielding wall, the cut surface of the cylindrical tube body by a plane including the axis can be V-shaped. A coupler base in which an annular groove is formed, and a second tube on the inner peripheral wall of a cylindrical tube that is slidably fitted along the outer peripheral wall surface of the coupler base.
Although the first annular protrusion is in airtight sliding contact with the groove bottom of the annular groove, and the first annular protrusion that can be removed from the groove bottom is in airtight sliding contact with the groove bottom of the second annular groove from beginning to end, the first annular protrusion While the strip is in airtight sliding contact with the groove bottom of the second annular groove, the compressed fluid supply source is connected to the compressed fluid passage forming hole opened in the groove bottom of the third annular groove. It is brought into sliding contact with the groove bottom closer to the connecting part side, and when the first annular protrusion is separated from the groove bottom of the second annular groove, it is brought into sliding contact with the groove bottom on the opposite side. In addition to the second annular protrusion, the inner circumference of the edge of the coupler base on the side of the plug insertion/removal section is provided with a notch for releasing the plug locking state using a small plug locking ball. The coupler body consists of a rider and one end can be airtightly inserted into the plug insertion/removal part of the coupler body, and the outer peripheral wall has an annular groove for inserting a small plug locking ball. 1. A pipe joint for supplying compressed fluid, characterized in that the other end is a plug serving as a connection part to a side to be supplied with compressed fluid.
