Description

[Brief explanation of the drawing]

The drawings show the configuration of a coupler for an air tool in which the compressed fluid supply pipe joint according to the present invention is implemented. Fig. 1 is a longitudinal cross-sectional view when the air passage is blocked, and Fig. 2 is a longitudinal cross-sectional view when the air passage is blocked. FIG. 6 is a longitudinal cross-sectional view when air passages are in a communicating state. -1; Coupler main body, 2; Air passage, 3; Large diameter part, 4; Stepped part with bite, 5; Rubber hose connection pipe, 6; Tubular member with thread part for holding rubber hose, 7; Rubber hose, 8

Claims (1)

[Scope of utility model registration request] A cylindrical coupler having a connecting part to a compressed fluid supply source at one end of the cylindrical tube and a compressed fluid delivery part at the other end communicating with the inside of the cylindrical coupler main body through the cylindrical wall of the cylindrical coupler main body. , and among the separate cylindrical extending portions extending so that the axes of the cylindrical coupler main body and the axes intersect diagonally, the one closer to the connecting portion side of the cylindrical coupler main body The open end of only one cylindrical extension part is a first cylindrical part with a small inner diameter, and the first cylindrical part is followed by a second cylindrical part with a large diameter. A cylindrical valve box is formed at the extending portion, and a compressed fluid passage is formed in the cylindrical valve box to communicate with the connecting portion side of the cylindrical coupler main body and to communicate with the compressed fluid delivery portion side. A valve seat sleeve, which is provided with a hole and has an inner diameter smaller than the inner diameter of the second cylindrical part, is tightly fitted and secured to the second cylindrical part with a space therebetween, and both ends thereof are attached to the valve body. a rod with a pushing part protruding from both ends thereof, the valve body for opening and closing the hole for forming a compressed fluid passage, and the valve body closing the hole for forming a compressed fluid passage;
When the compressed fluid passage is blocked, the valve body is airtightly fitted into the second cylindrical part, and when the valve body opens the compressed fluid passage forming hole and communicates the compressed fluid passage, a second piston-like part that is pulled out and removed from the second cylinder-like part;
When the second piston-like part starts to be inserted into the cylindrical part, it is pulled out and removed from the first cylindrical part, and when the second piston-like part starts to be pulled out and removed from the second cylindrical part, it is fitted into the first cylindrical part in an airtight manner. 1. A pipe joint for feeding compressed fluid, characterized in that a valve rod with a pushing part, which is formed by fixing a first piston-shaped part in this order, is arranged so as to be able to reciprocate and slide.
