상수관의 연결 구조{Structure for connecting water pipe line}Structure for connecting water pipe line

본 발명은 상수관의 연결 구조에 관한 것으로, 상수관을 연결하는 시공현장에서 상수관의 외주면에 나사를 가공하지 않고서도 상수관을 간편하게 연결할 수 있을 뿐만 아니라 연결된 상수관 사이의 누수를 확실하게 방지할 수 있고, 연결 상태가 견고하게 되도록 한 상수관의 연결 구조에 관한 것이다.
The present invention relates to a connection structure of water pipes, in a construction site for connecting water pipes, it is possible to easily connect the water pipes without machining screws on the outer circumferential surface of the water pipes as well as to reliably prevent leakage between the connected water pipes. The connection structure of the water pipe which can be made and the connection state is made strong.

일반적으로 상수관을 연결함에 있어서는 시공현장에서 연결하고자 하는 제1, 제2 상수관의 연결 단부 외주면에 탭핑장치에 의하여 수나사부를 가공하고, 누수방지용 테이프를 감은 다음 양측 내주부에 암나사부가 형성된 연결구를 조임방향으로 돌려서 제1 상수관의 수나사부에 연결구의 일측 암나사부가 나사결합에 의하여 연결되도록 하고, 다시 제2 상수관을 조임방향으로 돌려서 제2 상수관의 수나사부가 연결구의 타측 암나사부에 나사결합에 의하여 연결되도록 하는 방식이 널리 사용되어 왔다.In general, in the connection of water pipes, the male thread part is processed on the outer circumferential surface of the first and second water pipes to be connected at the construction site by a tapping device, the water leakage prevention tape is wound, and the connector with the female thread is formed on both inner peripheral parts. Rotate in the tightening direction so that one female threaded portion of the connector is connected to the male threaded portion of the first water pipe by screwing, and again, the male screwed portion of the second water pipe is screwed to the other female threaded portion of the connector by turning the second water pipe in the tightening direction. The way to be connected by has been widely used.

그러나 이러한 상수관의 연결 구조는 시공현장에서 일일이 상수관의 단부 외주면에 태핑장치에 의하여 수나사부를 가공해야 하므로 그 작업이 매우 불편할 뿐만 아니라 누수방지 기능이 단지 누수방지용 테이프에 의존하게 되기 때문에 시간이 경과함에 따라 수돗물이 누수되는 문제점이 있다.However, since the connection structure of the water pipe has to be processed by the tapping device on the outer circumferential surface of the water pipe at the construction site, the work is very inconvenient, and since the leakage preventing function depends only on the water leakage preventing tape, There is a problem in that the tap water leaks.

이러한 종래기술의 문제점을 일부 해결하기 위한 연결 컨넥터는 단면이 원형인 일정 길이의 중공형 몸체와 상기 몸체의 양단에서 이탈되지 않으면서 자체 회전이 가능하도록 설치되는 한 쌍의 연결잭 및 상기 몸체와 연결잭 사이에 개재되어 상기 연결잭을 상기 몸체의 중앙 방향으로 항상 가압하기 위하여 상기 몸체가 관통되는 방식으로 설치되는 스프링을 포함하며, 상기 한 쌍의 연결잭이 각 관로에 결합되는 구조를 가짐으로써, 연결 컨넥터의 간단한 조작만으로 상수관을 연결시키거나 해체시킬 수 있으며, 별도의 공구를 사용하지 않아도 되고, 오랜 기간 사용하여도 누수 등의 문제점이 발생하지 않아 결과적으로 제품의 신뢰성이 향상될 수 있도록 한 상수관의 연결 구조가 대한민국 등록특허 제1175311호(2012.08.13.) "상수관의 연결 구조"에 개시되어 있다.The connecting connector for solving some of the problems of the prior art is a hollow body having a predetermined cross-section and a pair of connecting jacks installed to allow self-rotation without being separated from both ends of the body and between the body and the connecting jack. It includes a spring is installed in such a way that the body is penetrated in order to always press the connecting jack in the direction of the center of the body, the pair of connecting jacks are coupled to each conduit, thereby simplifying the connection of the connector The water pipe can be connected or dismantled only by operation, no need to use a separate tool, and the water pipe can be improved to improve the reliability of the product as a result of leakage of water even after long use. The structure is disclosed in the Republic of Korea Patent No.1175311 (2012.08.13.) "Connection structure of the water pipe" There is.

그러나 상기 개선된 종래기술에 의한 등록특허의 상수관 연결 구조는 연결이 간단하다는 장점이 있으나 상수관을 연결잭으로 연결하기 위하여 상수관의 외주면에 결합홈을 형성하는 것이기 때문에 상수관의 제조가 다소 난해하고, 상수관의 단부 사이에 삽입되는 하나의 패킹만으로 누수를 방지하는 구조로 되어 있기 때문에 누수 방지 효과가 다소 낮아지는 문제점이 있다.
However, the improved water pipe connection structure of the registered patent according to the improved prior art has the advantage that the connection is simple, but because the coupling groove is formed on the outer circumferential surface of the water pipe to connect the water pipe to the connection jack is somewhat difficult to manufacture the water pipe In addition, there is a problem in that the leakage prevention effect is somewhat lowered because the structure is designed to prevent leakage by only one packing inserted between the ends of the water pipe.
