본 발명은 유체(流體)의 압력전달 및 이송을 행하는 튜우브나 호오스등의 튜우브체와, 각종의 기기를 접속하기 위한 관이음매에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to tubing bodies such as tubs and hoses for performing pressure transfer and transfer of fluids, and pipe joints for connecting various devices.

종래, 공기, 기름, 물등의 유체를 이용하는 기기에, 이들 유체를 공급하는 튜우브나 호오스등의 튜우브체를 연결하는 관이음매는, 예를들면 제6도에 도시한 바와같이, 본체(11)의 내부단부를 향해서 순차 삽입된 시일제(12), 백링(13), 레테이닝링(14), 스텝(段付) 칼라(15), 및 스텝해방링(16)으로 구성된 것이 존재한다. 그리고, 이 관이음매는, 스텝칼라(16)으로 구성된 것이 존재한다. 그리고, 이 관이음매는, 스텝칼라(15)와 스텝해방링(16)이, 양자의 단부(15a), (16a)에 의해 서로 걸어 맞추어지지만, 양자사이에 약간의 여유(A)가 존재하고 있기 때문에, 튜우브체(17)가 삽입된 뒤에도, 스텝해방링(16)을 화살표 방향으로 누르므로서, 제6도 하반부에 표시된 바와같이, 리테이닝링(14)의 발톱부(14a)가 변형해서 튜우브체(17)와의 걸어맞춤이 해제되므로, 튜우브체(17)를 빼낼 수 있다. 또, 스텝해방링(16)의 눌리지 않는 상태에서는, 제6도 상반부에 표시하는 바와같이, 리테이닝링(14)는 발톱부(14a)의 강한 탄발력에 의해 튜우브체(17)에 파고들어가서 튜우브체(17)의 탈락을 지지하고 있다.Conventionally, as shown in FIG. 6, pipe joints connecting tubing bodies such as tubes or hoses for supplying these fluids to equipment using fluids such as air, oil, water, etc. What consists of the sealing compound 12, the back ring 13, the retaining ring 14, the step collar 15, and the step release ring 16 which were inserted one by one toward the inner end part. And this pipe joint is what consists of the step collar 16. In this pipe joint, although the step collar 15 and the step release ring 16 are engaged with each other by the end portions 15a and 16a of both, a slight margin A exists between them. Therefore, even after the tubing body 17 is inserted, the claw portion 14a of the retaining ring 14 is deformed as shown in the lower half of FIG. 6 by pressing the step release ring 16 in the direction of the arrow. Since the engagement with the tubular body 17 is canceled, the tubular body 17 can be taken out. In the state where the step release ring 16 is not pressed, as shown in the upper half of FIG. 6, the retaining ring 14 penetrates the tubular body 17 by the strong elastic force of the claw portion 14a. The dropping of the tubular body 17 is supported.
