Description

꼬임방지 기능을 갖는 수도배관용 고압호스 연결구 {High pressure hose connector for water pipe with anti-twist function} High pressure hose connector for water pipe with anti-twist function}

본 발명은 꼬임방지 기능을 갖는 수도배관용 고압호스 연결구에 관한 것으로, 보다 상세하게는 세면대, 샤워기, 씽크대 등에 설치되는 각종 수전금구와 수도배관 등의 관연결부에 연결하는 고압 호스의 단부에 설치되는 연결구의 구조를 개선하여 관연결부에 결합 시에도 고압호스와 연결된 니플의 원활한 자유 회전을 보장할 수 있는 고압호스 연결구에 관한 것이다.The present invention relates to a high-pressure hose connector for water pipes having a twist prevention function, and more particularly, installed at the end of a high-pressure hose connected to various faucet fittings installed in a wash basin, shower, sink, etc. and pipe connections such as water pipes. It relates to a high pressure hose connector that can ensure smooth free rotation of a nipple connected to a high pressure hose even when it is coupled to a pipe connection by improving the structure of the connector.

일반적으로, 건물의 욕실, 주방 등에 설치된 세면대, 씽크대 또는 양변기 등에 설치된 각종 수전금구와 외부에서 인입된 급수파이프(수도배관)를 연결하기 위해서는 각종 수전금구와 급수파이프 각각의 위치에 구애받지 않고 연결이 간편하도록 변형이 자유로운 플렉시블 호스가 사용된다.In general, in order to connect various faucet brackets installed in the bathroom, kitchen, etc. of a building with various faucet brackets installed on the sink, sink, or toilet of a building, the connection is made regardless of the location of the various faucet brackets and water supply pipes. For simplicity, a flexible hose with free deformation is used.

이때, 상기 플렉시블 호스의 양 끝단에는 각종 수전금구와 급수파이프를 상호 연결시킬 수 있도록 등록실용신안 제20-0438767호 및 등록실용신안 제20-0300326호에 기술된 연결조인트가 설치되는 것이 일반적이다.At this time, the connection joints described in Utility Model Registration No. 20-0438767 and Utility Model Registration No. 20-0300326 are generally installed at both ends of the flexible hose so that various faucets and water supply pipes can be interconnected.

이러한 종래 연결조인트의 경우 플렉시블 호스의 일단 또는 양단에 끼움결합되며, 일단에 원통형 패킹결합돌기가 구비되고 타단에는 테이퍼진 쐐기형 웨지편이 구비된 니플과, 상기 패킹결합돌기의 후방 외주면에 직경이 확대 형성되며, 상기 패킹결합돌기에 삽착된 고무패킹을 지지하는 패킹지지플랜지와, 상기 니플 일단의 패킹결합돌기에 결착된 상태로 패킹지지플랜지에 의해 지지되며, 각종 수전금구 또는 급수파이프와 연결너트 간의 나사 체결 시 기밀을 유지하여 누수를 방지하는 고무패킹과, 상기 웨지편이 관통 돌출되는 상태로 고무패킹과 함께 니플이 내삽됨과 동시에 플렉시블 호스의 일단 또는 양단에 자유 회전이 가능하게 결합되며, 개방된 일측 내주연에 암나사부가 구비된 연결너트로 구성되는 등 각종 수전금구와 급수파이프를 연결하는데 통상적으로 사용되고 있는 관 연결방법으로서 주로 사용되고 있었다.In the case of such a conventional connection joint, a nipple is fitted at one end or both ends of a flexible hose, and a cylindrical packing engaging protrusion is provided at one end and a tapered wedge-shaped wedge piece is provided at the other end, and the diameter is enlarged on the rear outer circumferential surface of the packing engaging protrusion. It is formed and is supported by a packing support flange that supports the rubber packing inserted into the packing coupling protrusion, and a packing support flange in a state bound to the packing coupling protrusion of one end of the nipple, and between various faucet brackets or water supply pipes and a connection nut. A rubber packing that maintains airtightness when screwing in to prevent leakage, and the nipple is inserted with the rubber packing in a state where the wedge piece protrudes through, and at the same time, it is freely rotated to one or both ends of the flexible hose, and the open side It was mainly used as a pipe connection method commonly used to connect various faucet fittings and water supply pipes, such as consisting of a connection nut provided with a female thread on the inner periphery.

그러나, 상기와 같이 구성된 조앨 연결 조인트의 경우 각종 수전금구 또는 급수파이프와 연결너트 간의 나사 체결 시 원통형 패킹결합돌기가 형성된 니플의 일단에 면착되는 상태로 연결너트에 내삽되는 고무재질의 고무패킹이 기밀하게 밀착되지 못하여 이를 통한 공극 발생 시 고무패킹과 연결너트 사이로 누수가 발생될 뿐만 아니라, 누수를 방지하기 위해 사용자가 스패터 등 조임공구를 이용하여 연결너트를 과도하게 조이게 되면 상기 고무패킹에 연결너트이 회전에 따른 압축력이 작용하게 되면서 상기 니플의 패킹지지플랜지에 고무패킹이 가압 밀착되는 등 상기 니플의 패킹지지플랜지와 고무패킹 간의 과도한 마찰력 증가로 인해 상기 연결너트의 회전 시 고무패킹 및 니플 모두 회전하게 됨과 아울러, 상기 니플 타단의 웨지편에 끼움 결합된 플렉시블 호스 역시 함께 회전하게 되면서 결과적으로 상기 연결너트의 과회전에 따른 플렉시블 호스가 뒤틀리거나 꼬이게 되는 등의 커다란 문제점이 있었다.However, in the case of the jaw connection joint configured as described above, when screwing between various faucet brackets or water supply pipes and the connection nut, the rubber packing made of rubber that is inserted into the connection nut in a state that faces to one end of the nipple with the cylindrical packing coupling protrusion is airtight. When a gap occurs through the rubber packing and the connection nut, not only leakage occurs between the rubber packing and the connection nut, but also if the user tightens the connection nut excessively using a tightening tool such as spatter to prevent leakage, the connection nut is attached to the rubber packing. Both the rubber packing and the nipple rotate when the connecting nut rotates due to an increase in excessive frictional force between the packing support flange and the rubber packing of the nipple, such as the rubber packing pressurizes against the packing support flange of the nipple as the compression force is applied. In addition, as the flexible hose fitted to the wedge piece at the other end of the nipple also rotates, there is a large problem in that the flexible hose is twisted or twisted due to over-rotation of the connection nut.

또한, 상기와 같이 연결너트의 과회전에 따른 플렉시블 호스가 뒤틀리거나 꼬이게 될 경우 이로 인한 플렉시블 호스 내의 유체이동이 원활하게 이루어지지 않게 되는 문제점과 아울러 작업자가 각종 수전금구 또는 급수파이프에 체결된 연결너트의 결합력을 해제하여 뒤틀리거나 꼬인 플렉시블 호스를 고르게 편 후 다시 조이는 반복작업을 수행해야 하는 등 종래의 연결 조인트에 대한 연결시공 시 작업이 번거롭고, 시공시간의 증가와 그에 따른 비용이 상승되는 문제점 역시 있었다.In addition, when the flexible hose is twisted or twisted due to the over-rotation of the connection nut as described above, the fluid in the flexible hose does not move smoothly, as well as the connection nut fastened to various faucet brackets or water supply pipes. There was also a problem in that the work was cumbersome during the connection construction for the conventional connection joint, such as having to perform repetitive work of releasing the bonding force of the twisted or twisted flexible hose evenly and then tightening it again, and the increase in construction time and the corresponding cost increase. .
