Claims

[Claims for Utility Model Registration] A small diameter portion, a conical portion extending from both ends of the small diameter portion in the central axis direction and expanding in the extending direction, and a conical portion extending from the conical portion coaxially with the conical portion and extending toward the inner periphery. an intermediate connecting pipe having a large diameter portion having a female thread; and an intermediate connecting pipe having a male thread screwed into the female thread on the outer periphery of one end side, and allowing the pipe to be connected to pass freely from the one end side to the other end side. A tightening member equipped with a through hole that is substantially coaxial with the central axis, the inner peripheral surface of the through hole includes a conical inner peripheral surface that becomes narrower from the one end to the other end, and there is a tightening member between the inserted pipe and the inner peripheral surface of the through hole. forming a narrow annular cavity toward the other end; holding a plurality of spheres and a nuclear sphere at approximately equal intervals within the annular cavity, and holding the nuclear sphere in the annular cavity; a locking member that biases the pipe in a narrowing direction; the locking member has a through hole through which the pipe passes, is fitted inside the conical part of the intermediate connecting pipe, and the tightening member is screwed into the large diameter part; In a pipe connecting device having a gasket that is pressed together and tightly grips a pipe inserted into the inside, it is noted that each of the plurality of balls described above has a roughness almost equivalent to a blank surface imparted to the surface. Characteristic pipe connection device.
