본 고안은 두개의 관을 상호 연결하기 위한 관접속구에 관한 것으로서 접속되는 관체가 원통상의 관접속구의 내에 삽입하도록 관체의 내면과 그 내주면과 적당한 간격이 유지되도록 취부되는 슬리브가 구비되어 그 슬리브는 소정의 온도 변화에 의해 내경이 확대되는 형상으로 변형되는 형상기억 합성수지로 구성되는 것이다.The present invention relates to a joint for interconnecting two tubes, the sleeve is provided with a sleeve which is maintained so as to maintain a proper distance from the inner surface and its inner circumferential surface of the tube so that the connected tube is inserted into the cylindrical tube. It is composed of a shape memory synthetic resin deformed into a shape in which the inner diameter is enlarged by a predetermined temperature change.

종래에 관을 접속하는 접속구로 서로 접속관 양편에서 관체를 삽입하여 고무링을 갖는 커플링을 나사식으로 결합하여 체결 연결하는 것이 있으나 이는 접속되는 관체 사이에서 틈이 생겨 누수현상이 발생하거나 커플링 사이에서도 밀접 되지 못하고 누수 될 뿐만아니라 연결 작업이 다소 불편함이 있었다.Conventionally, the connection port for connecting the pipe is to connect the couplings with rubber rings by inserting the pipes from both sides of the connection pipes, but the coupling is connected by screwing, but this is caused by a gap between the pipes to be connected, which causes water leakage or coupling. Not only did not close between the leaks, but also the connection work was inconvenient.

따라서, 본고안은 상술한 바와 같은 문제점을 해소 하고자 안출 된 것으로서 접속구 내에 삽착되어 있는 슬리브가 나합 접속되는 관체의 내부에 연접되도록 하는 것으로서 이를 첨부 도면에 의거 상세히 설명하면 다음과 같다.Therefore, the subject matter of the present invention is to solve the problems described above, and the sleeve inserted into the connection port is to be connected to the inside of the tubular body to be screwed connection as described in detail based on the accompanying drawings as follows.

접속구(20)의 양측에서 지지부(21)의 내면에 경사지게 나사부(21a)를 형성하고 그 중앙에 연결부(22)의 내면 내경이 다소 크게 환상형으로된 요구(22a)를 형성하여 슬리브(30)를 취부하되 슬리브(30)는 원통상의 유입부(31)의 중앙 외측에 연결부(33)에 의해 지지부(32)가 형성되고, 그 슬리브(30)는 소정의 온도 이상으로 되었을 때의 관체(10)의 내면에 삽입하는 선단부가 그 관체(10)의 내주면에 압접하여 내경이 확경 되도록 하는 형상기억 수지로 되는 것이다.On the both sides of the connector 20, the threaded portion 21a is formed to be inclined on the inner surface of the support portion 21, and in the center thereof, the inner surface of the connecting portion 22 forms a request 22a in which the inner diameter of the connecting portion 22 is somewhat large. The support 30 is formed by the connection part 33 in the center outer side of the cylindrical inflow part 31, and the sleeve 30 is a tubular body when the sleeve 30 became more than predetermined temperature ( The tip portion inserted into the inner surface of 10) is formed into a shape memory resin that presses against the inner circumferential surface of the tube 10 so that the inner diameter thereof can be increased in diameter.

이와같이 구성된 본고안의 실시예를 설명하면, 내면에 합성수지층(12)이 접종된 관체(10)의 선단 접속관(11) 외면에 경사형의 나사부(13)를 형성하여, 접속구(20)의 경사지게 형성된 나사부(21a)에 나합하면 관체(10)의 선단이 슬리브(30)의 지지부(32)에까지 나합되는데, 관접속구(20)에 구비되어 있는 슬리브(30)은 관접속구(20)의 동심원상으로 되어 원통상의 연접부(31)와 관접속구(20)의 연결부(22)의 요구(22a)내에 요입되어 있는 지지부(32)를 갖고 있다.Referring to the embodiment of the present invention configured as described above, the inclined screw portion 13 is formed on the outer surface of the tip connecting pipe 11 of the tubular body 10 in which the synthetic resin layer 12 is inoculated on the inner surface thereof, so that the connector 20 is inclined. When screwed into the formed threaded portion (21a), the front end of the tubular body 10 is screwed to the support 32 of the sleeve 30, the sleeve 30 provided in the tubing 20 is concentric with the tubular opening 20 It has the support part 32 recessed in the request 22a of the cylindrical connection part 31 and the connection part 22 of the connection port 20. As shown in FIG.

슬리브(30)의 연접부(31)은 관접속구(20)의 지지부(21) 내주면과 적정한 간격을 유지하고 있다. 슬리브(30)는 축심방향의 중아부가 약간 투텁게 되어있고 선단측으로 순차적으로 얇게 되어 있다. 접속구(20)에 관체(10)를 나합한 다음 적정 이상의 온도를 갖는 유체가 관체(10) 내부를 통과하게 되면 형상기억 합성수지로된 슬리브(30)의 원통상의 연접부(31)가 제2도면에 예시되고 제3도에 실시예가 도시된 바와 같이 직경이 확경되어 관체(10)의 내경면에 밀폐되게 적충되므로 누수 현상이 발생하지 않게된다.The connection part 31 of the sleeve 30 maintains the proper space | interval with the inner peripheral surface of the support part 21 of the connection port 20. As shown in FIG. The sleeve 30 is slightly thickened in the center of the axial direction, and is gradually thinned to the tip side. After joining the tubular body 10 to the connector 20 and passing a fluid having a temperature higher than an appropriate level through the tubular body 10, the cylindrical joint 31 of the sleeve 30 made of a shape memory synthetic resin is formed as a second. As illustrated in FIG. 3 and the embodiment is shown in FIG. 3, the diameter is increased in diameter, and the water is not leaked to the inner diameter surface of the tubular body 10.

특히, 본고안에서 접속구(20)와 관체(10)를 접속할때 특별히 가열이 필요하지 않게된다. 또한 제4도에 도시된 바와 같이 관체(10)의 내면과 슬리브(30)의 연접부(31) 사이에 고무탄성부재(40)의 O링을 개입하여 접속하게 되면 밀폐 상태를 이중으로 하게되어 누수현상을 이중 차단하게되는 효과를 얻게 되는 것이다.In particular, when connecting the connector 20 and the tubular body 10 in this article, no heating is particularly necessary. In addition, as shown in FIG. 4, when the inner surface of the tubular body 10 and the connecting portion 31 of the sleeve 30 are connected through the O-ring of the rubber elastic member 40, the sealed state is doubled. You will get the effect of double blocking leakage.

본고안의 특징은 특별히 별도의 기계장치가 없이도 관체를 용이하고 밀폐되게 접속하여 누수현상을 완벽하게 배재할 수 있다는 특징이 있는 것이다.The special feature of this paper is that the pipe can be easily and hermetically connected without any special mechanical device to completely eliminate the leakage phenomenon.
