플라스틱 주름관의 방수 연결구{CONNECTING AND SEALING DEVICE FOR A PLASTIC CORRUGATED PIPES}CONNECTING AND SEALING DEVICE FOR A PLASTIC CORRUGATED PIPES}

본 발명은 플라스틱 주름관의 방수 연결구에 관한 것으로, 더욱 상세하게는 플라스틱 주름관의 단부를 변경하여 방수기능과 이탈방지기능을 강화시킨 플라스틱 주름관의 방수 연결구에 관한 것이다.
The present invention relates to a waterproof connector of a plastic corrugated pipe, and more particularly, to a waterproof connector of a plastic corrugated pipe having an enhanced waterproof function and a departure preventing function by changing an end of the plastic corrugated pipe.

일반적으로 플라스틱 주름관은 전선관이나 액상 또는 가스를 수송하는 튜브 등을 내장하고 이들을 보호하는 관체(管體)로서, 몸체에 나선형 주름이 형성되어 굴곡성이 우수하고, 온도나 압력변화에 따라 신축하면서 내장재를 보호한다. 그러나, 이러한 플라스틱 주름관은 전체길이가 한정되어 있어, 여러 가지 관이음수단을 이용하여 상호연결하여 길이를 연장하여 사용하고 있다.In general, plastic corrugated pipes are conduits that contain wires or tubes for transporting liquids or gases and protect them. Spiral corrugations are formed on the body to provide excellent flexibility, and expand and contract the interior materials according to changes in temperature or pressure. Protect. However, these plastic corrugated pipes have a limited overall length, and are used by extending the length by interconnecting them using various pipe jointing means.

종래 주름관의 공지 관이음수단으로서는, 주름관이 소경인 경우에는 연결부분에 장착되는 이음관을 테이프로 감아서 접속하는 방법과, 주름관이 대경인 경우에는 연결부분에 장착되는 2분할된 이음부재를 덧씌워 나사체결하는 방법이 있다.As a conventional pipe fitting means of a conventional corrugated pipe, if the corrugated pipe is a small diameter, a method of connecting and connecting the joint pipe mounted on the connection portion with a tape, and when the corrugated pipe is large diameter, add a two-part joint member attached to the connection portion. There is a method to fasten the screws.

한국 공개특허 제10-2005-0108821호에는 상호연결되는 주름관들의 연결부위를 소정의 폭으로 감싸는 프레임부재와, 해당 프레임부재의 내부면과 주름관들의 외주면 사이에 설치되고 외부로부터 가해지는 주입부를 가지며, 이 주입부를 통하여 주입되는 유체의 압력에 의해 팽창되어 상기 프레임부재와 주름관의 외주면을 가압하여 주름관을 연결하는 신축부재를 포함하는 주름관 연결장치를 개시하고 있다.Korean Patent Publication No. 10-2005-0108821 has a frame member surrounding a connecting portion of corrugated pipes that are interconnected with a predetermined width, and an injection portion installed between the inner surface of the frame member and the outer peripheral surface of the corrugated pipes, and applied from the outside, Disclosed is a corrugated pipe connecting device that includes an expansion and contraction member that expands by the pressure of a fluid injected through the injection portion and presses the outer peripheral surface of the frame member and the corrugated pipe to connect the corrugated pipe.

또한, 한국 등록특허 제10-0586455호에는 각 파형관(주름관)의 연결부분 골에 감기게 되는 밀폐부재와, 열결될 파형관을 동시에 감게 되는 고무재질 덮개와, 나사축의 양측을 조임너트 체결로 결합시켜 파형관을 연결하도록 형성된 연결체와, 상기 연결체의 고정돌기를 외부에서 감싸아 나사축의 양측을 조임너트 체결로 견고하게 결합시키는 이탈방지체로, 구성되는 파형관의 연결 및 이탈방지용 연결구를 개시하고 있다.In addition, in Korean Patent No. 10-0586455, the sealing member wound around the corrugated part of each corrugated pipe (corrugated pipe), the rubber material cover that simultaneously winds the corrugated pipe to be thermally coupled, and the both sides of the screw shaft are joined by tightening the tightening nut. Disclosed is a connecting body formed to connect a corrugated pipe, and a release preventing body that firmly couples both sides of the screw shaft by tightening a tightening nut by surrounding a fixing protrusion of the connecting body from the outside, and discloses a connector for connecting and preventing a corrugated pipe.

그러나, 공지의 이러한 관이음수단은 작업단계가 복잡하고, 작업공수가 많이 들고, 또한, 방수처리가 제대로 이루어지지 않는 문제점과 연결된 주름관이 쉽게 분리 이탈되는 문제점이 있었다.
However, such a known pipe joint means has a problem in that the work step is complicated, the work is expensive, and the corrugated pipe connected to the problem that the waterproofing is not properly performed is easily separated and separated.
