Are screwed together, and the pipe 3 is pressed and connected to the inner surface of the joint member 1.

이때, 상기 제1이음부재(1)의 단부 외주면에는 경사면(1a)이 형성되고, 상기 제2이음부재(5)의 내부에는 상기 경사면(1a)을 타고 미끄러지는 대향경사면(5a)이 형성되어, 상기 제2이음부재(5)를 조임에 따라 상기 경사면(1a)이 형성된 부위가 변형하여 파이프(3)를 강하게 압착하게 되어 파이프(3)가 빠지지 않게 된다.At this time, the inclined surface (1a) is formed on the outer peripheral surface of the end portion of the first joint member 1, the opposite inclined surface (5a) is formed in the interior of the second joint member (5) sliding on the inclined surface (1a) As the second joint member 5 is tightened, a portion where the inclined surface 1a is formed is deformed to strongly compress the pipe 3 so that the pipe 3 does not fall out.

그런데, 상기 도1에 도시한 파이프 연결장치는 금속재등으로 된 파이프의 연결에 적합한데, 한번 연결된 파이프와 제1이음부재의 경사면부위가 변형되므로, 연결장치를 재차 사용하지 못하게 된다.However, the pipe connecting device shown in FIG. 1 is suitable for connecting a pipe made of metal or the like, and since the inclined surface portion of the pipe connected once and the first joint member is deformed, the connecting device cannot be used again.

그리고, 종래 수지재로 된 파이프를 연결하는 연결장치가 개시되어 있으나, 이러한 수지재의 파이프를 연결하는 종래의 연결장치는 그 구조가 복잡하고 연결력이 강하지 못하여 고압에서는 사용할 수 없다는 문제점이 있었다.In addition, although a connecting device for connecting a pipe made of a conventional resin material has been disclosed, the conventional connecting device for connecting a pipe made of such a resin material has a problem in that its structure is complicated and its connection strength is not strong, so it cannot be used at high pressure.

따라서 본 고안은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 고안의 목적은 수지재 파이프의 연결이 용이할 뿐만 아니라 견고하며 파이프를 분리시킨 후에 재사용이 가능한 파이프 연결장치를 제공하는 데 있다.Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a pipe connecting device that is easy to connect the resin pipe and is also robust and reusable after separating the pipe.
