Abstract

PURPOSE: A pipe connector is provided to simplify a connecting and decomposing work without damage to a pipe by producing a nipple and a bushing movably and to excellently prevent water leakage. CONSTITUTION: A pipe connector consists of a bushing(13) forcibly inserted in an inner circumferential face of a pipe(1) by a pipe connecting unit(13-1); a press fastening ring(12) of which bore is resiliently contracted and pressed on an outer circumferential face of the pipe if a slant face(12-1) is pressed by a slant face(10-1) of a fastening nut(10); and a nipple(15) of which sealing sill(15-2) is pressed by a packing(14) and a front end face(15-1) is adhered to a fastening flange(13-3) of the bushing. Upon connecting the pipe in a narrow space, a front end of the pipe is resiliently pulled back. The pipe connecting unit(13-1) is inserted while inserting the fastening nut and the press fastening ring in order. The sealing portion of the bushing is inserted in the packing. When the pipe and the nipple are put coaxially, a female screw unit(10-2) of the fastening nut is combined with a male screw unit of the nipple. If the slant face of the fastening nut is adhered to a rear side face of the fastening flange by pushing the press fastening ring, the press fastening ring is not processed any more. Upon tightening the fastening nut more, the slant face(10-1) contracts the bore of the press fastening ring while sliding along the slant face(12-1). Thus, the press fastening ring fixes the pipe while pressed on the outer circumferential face of the pipe.

Description

관 연결구{PIPE CONNECTOR}PIPE CONNECTOR}

본 발명은 관 연결구에 관한 것으로, 특히 협소한 공간에서 관과 관을 연결할 때 관을 구부리거나 절단한 후 연결하는 작업없이 간단히 연결이 가능한 관 연결구에 관한 것이다.The present invention relates to a pipe connector, and more particularly to a pipe connector that can be easily connected without connecting the pipe after bending or cutting the pipe when connecting the pipe in a narrow space.

종래의 관 연결구는 도1 및 도2에 도시한 바와같이 관(1)을 연결부싱(3)에 끼운 상태에서 조임너트(6)를 니플(2)에 나사결합한 상태로 조이게 되면 압착조임링(4)이 관의 외주면을 따라 이동되면서 니플의 내주면과 연결부싱의 외주면 사이로 끼워지게 된다.1 and 2, the conventional pipe connector is tightened when the tightening nut 6 is screwed to the nipple 2 while the pipe 1 is inserted into the connecting bushing 3. 4) is moved along the outer circumferential surface of the tube and is inserted between the inner circumferential surface of the nipple and the outer circumferential surface of the connecting bushing.

이때, 니플(2)의 내주면과 연결부싱(3)의 외주면 사이로 진행되는 압착조임링(4)은 그 내경이 축소되면서 관(1)의 외주면을 조이게 된다.At this time, the compression tightening ring 4 which proceeds between the inner circumferential surface of the nipple 2 and the outer circumferential surface of the connecting bushing 3 tightens the outer circumferential surface of the pipe 1 while its inner diameter is reduced.

그러나, 종래의 관 연결구는 관(1)내를 흐르는 유체가 패킹(5)에 의해 실링(Sealing)이 이루어지나 패킹(5)이 관(1)의 내주면과의 마찰에 의해 쉽게 손상되어 누수발생의 문제가 있다.However, in the conventional pipe connector, the fluid flowing in the pipe 1 is sealed by the packing 5, but the packing 5 is easily damaged by friction with the inner circumferential surface of the pipe 1, causing leakage. There is a problem.

또한, 협소한 공간에 주로 사용되는 관 연결구는 니플(2)과 연결부싱(3)이 일체형으로 제작되기 때문에 연결부싱을 관(1)에 삽입하거나 관으로부터 빼내기 위해서 관(1)을 강제로 구부리거나 절단하게 되고, 이로써 관(1)에 손상을 주게될 뿐만아니라 관의 절단시 재시공의 문제가 있어 관의 연결조립 및 연결해체작업이 매우 번거로운 단점이 있다.In addition, since the pipe connector mainly used in a narrow space is made of the nipple (2) and the connecting bushing (3) integrally, the pipe (1) is forcibly bent to insert or remove the connecting bushing into the pipe (1) Or cut, thereby causing damage to the tube (1) as well as the problem of reconstruction when cutting the tube has the disadvantage of very cumbersome connection assembly and disconnection of the tube.

본 발명은 니플과 부싱을 분리형으로 제작함으로써 관과 관의 연결 또는 해체시 관에 전혀 손상을 입히지 않으면서 연결 및 해체작업이 간단하고, 누수의 방지가 우수한 관 연결구를 제공함에 그 목적이 있다.The object of the present invention is to provide a pipe connector that is easy to connect and dismantle without damaging the pipe at all when connecting or dismantling the nipple and the bushing separately, and excellent in preventing leakage.

The secondary sealing is performed by being in close contact with the front side of the blade.

그리고, 본 발명에 따른 압착조임링(12)은 그 내경이 탄성적으로 확축되도록 그 일측에 절개부(12-2)가 형성되어 있고, 그 외주면 한쪽이 경사면(12-1)을 이루도록 형성되어 있다.In addition, the compression clamping ring 12 according to the present invention has a cutout portion 12-2 formed at one side thereof so that the inner diameter thereof is elastically expanded, and one outer peripheral surface thereof is formed to form an inclined surface 12-1. have.

여기서, 조임너트(10)의 암나사부(10-2)가 니플(15)의 수나사부(15-1)를 따라 조여지게 되면 조임너트(10)의 경사면(10-1)이 압착조임링(12)의 경사면(12-1)을 밀어서 부싱(13)의 조임플랜지(13-3)에 밀착시키게 된다.Here, when the female thread portion 10-2 of the tightening nut 10 is tightened along the male thread portion 15-1 of the nipple 15, the inclined surface 10-1 of the tightening nut 10 is a crimping ring ( The inclined surface 12-1 of 12 is pushed to bring it into close contact with the tightening flange 13-3 of the bushing 13.

또한, 압착조임링(12)이 조임플랜지(13-3)의 후방측면에 밀착되면서 더이상 진행되지 않게 되면 조임너트의 경사면(10-1)이 압착조임링(12)의 경사면(12-1)을 타고 슬라이딩되면서 압착조임링의 내경을 축소하게 되고, 이에 따라 압착조임링은 관(1)의 외주면에 압착되면서 관을 고정시키게 된다.In addition, when the crimping fastening ring 12 is in close contact with the rear side of the tightening flange 13-3 and no longer proceeds, the inclined surface 10-1 of the tightening nut is inclined 12-1 of the crimping fastening ring 12. Sliding to reduce the inner diameter of the compression tightening ring, accordingly, the compression tightening ring is fixed to the tube while being pressed on the outer peripheral surface of the pipe (1).

이하, 본 발명의 작용을 설명한다.The operation of the present invention will be described below.

협소한 공간에서 관연결시 먼저, 니플(15)과 동일축상에 놓인 관(1)의 선단측을 탄성적으로 약간 젖힌 후 조임너트(10)와 압착조임링(12)을 차례로 끼우면서 부싱(13)의 관연결부(13-1)를 삽입시킨 다음, 부싱(13)의 실링부(13-2)에 패킹(14)을 끼운다.When connecting pipes in a narrow space, first, the tip side of the pipe (1) lying on the same axis as the nipple (15) is slightly reeled elastically, and then the bushing ( Insert the pipe portion 13-1 of 13), and then insert the packing 14 into the sealing portion 13-2 of the bushing 13.

그리고, 관(1)이 니플(15)과 동일축상에 놓이면 니플(15)의 실링턱(15-3)을 패킹(14)에 밀착시킨 상태에서 조임너트(10)의 암나사부(10-2)를 니플(15)의 수나사부(15-1)에 나사결합시키게 된다.Then, when the pipe 1 is placed on the same axis as the nipple 15, the female threaded portion 10-2 of the tightening nut 10 in a state where the sealing jaw 15-3 of the nipple 15 is brought into close contact with the packing 14. ) Is screwed into the male screw portion 15-1 of the nipple 15.

여기서, 조임너트(10)를 돌리면서 니플(15)의 수나사부(15-1)에 대한 조임너트(10)의 암나사부(10-2)의 나사결합을 진행시키게 되면 조임너트가 관(1)의 외주면을 따라 니플(15)측으로 이동하게 된다.Here, when the tightening nut 10 is screwed into the female threaded portion 10-2 of the tightening nut 10 with respect to the male threaded portion 15-1 of the nipple 15, the tightening nut is connected to the pipe 1 Nipple 15 is moved along the outer circumferential surface thereof.
