Description

파이프의 연결장치{omitted}Connection of pipes {omitted}

본 발명은 결합된 연결장치에 파이프를 끼워넣는 것만으로 기밀이 완벽하게 유지되는 동시에 걸림부재가 뒤로 밀려나지 않고 견고히 유지되는 상태로 연결되게 한 원터치 삽입식 파이프의 연결장치에 관한 것이다.The present invention relates to a one-touch plug-in pipe connecting device which allows the connection to be maintained in a tightly maintained state without being pushed back while only keeping the airtightness completely by inserting the pipe into the coupled connecting device.

종래 파이프의 연결장치는 도 1에 도시된 대한민국 실용신안 공고번호 제94-3804호에서와 같이 연결부재(a)에 패킹(b)과 걸림부재(c)를 끼우고 너트(e)를 체결함으로써 파이프(f)를 결합된 연결장치에 끼우게 되면 걸림부재(c)의 경사진 걸림편(d)이 파이프(f)를 물어주도록 구성되거나, 도 2에 도시된 대한민국 실용신안 등록번호 제142425호에서와 같이 걸림부재(c)의 걸림편(d)을 일직선으로 형성하고 이 걸림편(d)이 파이프(f)가 끼워지는 방향으로 결합하는 동시에 너트(e)쪽에 경사면(g)을 형성하는 주름 파이프의 연결장치를 제안 되어졌다.Conventional pipe connecting device by inserting the packing (b) and the locking member (c) to the connecting member (a) as shown in the Republic of Korea Utility Model Publication No. 94-3804 shown in Figure 1 by fastening the nut (e) When the pipe (f) is inserted into the coupling device coupled to the inclined locking piece (d) of the locking member (c) is configured to ask the pipe (f), or the Republic of Korea Utility Model Registration No. 142425 As described above, the engaging pieces d of the locking member c are formed in a straight line, and the locking pieces d are coupled in the direction in which the pipe f is fitted, and at the same time, the inclined surface g is formed on the nut e side. A connector for corrugated pipes has been proposed.

또한 도 3에 도시된 바와 같이 연결부재(a)에 걸림부재(c)와 원형 단면을 갖는 패킹(b)를 끼워 너트(e)로 체결하는 파이프의 연결장치가 사용되어졌다.In addition, as shown in FIG. 3, a connecting device of a pipe for fastening with a nut (e) by fitting a locking member (c) and a packing (b) having a circular cross section to the connecting member (a).

그러나 이와같이 된 종래의 연결장치들은 패킹(b)의 위치가 파이프(f)의 외경에 위치하기 때문에 파이프(f)의 끝부분과 연결부재(a)사이의 기밀을 효과적으로 유지할 수 없었을 뿐만 아니라 외력에 의해 걸림부재(c)가 후퇴됨으로써 기밀상태가 쉽게 손상되는 등의 문제점이 있었다. However, in the conventional connection devices, the packing (b) is not only able to effectively maintain the airtight between the end of the pipe (f) and the connecting member (a) because the position of the packing (b) is located at the outer diameter of the pipe (f). As a result, the locking member c is retracted, so that the airtight state is easily damaged.

본 발명이 해결하고자 하는 과제는 결합된 연결장치에 파이프를 끼워넣는 것만으로 기밀이 완벽하게 유지되는 동시에 걸림부재가 뒤로 밀려나지 않고 견고히 유지되는 상태로 연결될 수 있게 한 원터치 삽입식 파이프 연결장치를 제공하기 위한 것이다.The problem to be solved by the present invention is to provide a one-touch insert pipe connecting device that can be connected in a tightly maintained state without being pushed back while the airtightness is perfectly maintained just by inserting the pipe into the combined connecting device. It is to.

도 7은 본 발명의 연결부재(10)와 고정부재(60)를 체결부재(100)으로 감합하여 결합하는 실시예를 보인 도면으로써, 이것은 도시된 바와 같이 연결부재(10)의 결합공(12)쪽 외경에 감입부(14)를 돌출 형성하고, 상기 고정부재(60)의 결합부(62)를 상기 감입부(14)와 마주닿게 형성하며, 한쪽에는 상기 감입부(14)와 결합부(62)의 폭보다 긴 삽입부(101)가 이루어지고 다른 한쪽에는 상기 결합부(62)에 밀착되는 돌출부(102)가 형성된 체결부재(100)로 상기 삽입부(101)에 감입부(14)와 결합부(62)가 완전히 삽입된 상태에서 삽입부(101)의 끝을 구부려 감입부(14)를 감싸도록 결합하여서 된 것이다.FIG. 7 is a view illustrating an embodiment in which the connecting member 10 and the fixing member 60 of the present invention are fitted by coupling to the fastening member 100, which is a coupling hole 12 of the connecting member 10 as shown. The indentation portion 14 is formed to protrude from the outer side, and the coupling portion 62 of the fixing member 60 is formed to face the indentation portion 14, and the indentation portion 14 and the coupling portion are formed on one side thereof. The insertion part 101 longer than the width of the 62 is formed, and on the other side, the insertion part 14 is inserted into the insertion part 101 by a fastening member 100 having a protrusion 102 which is in close contact with the coupling part 62. ) And the coupling portion 62 are combined to bend the end of the insertion portion 101 to surround the indentation portion 14 in a completely inserted state.

이와같이 된 본 발명은 도 8에 도시된 바와 같이 주름파이프(90)가 체결부재(80)쪽에서 끼워지게 되는 것으로, 상기 걸림부재(50)의 걸림편(53)이 골부위(91)에 끼워지게 된다.In the present invention, as shown in FIG. 8, the pleated pipe 90 is fitted at the fastening member 80, such that the locking piece 53 of the locking member 50 is fitted at the bone portion 91. do.

본 발명의 연결장치를 조립하는 순서는 다음과 같다.The order of assembling the connecting device of the present invention is as follows.

연결부재(10)의 결합공(12)에 패킹(20), 지지부재(30), 가이드 링(40), 걸림부재(50)를 순서대로 삽입한후 고정부재(60)의 경사 고정돌부(61)가 걸림편(53)의 후방에서 끼워진 상태에서 체결부재(80) 또는 (100)를 이용하여 연결부재(10)와 고정부재(60)를 결합한다.After inserting the packing 20, the support member 30, the guide ring 40, and the locking member 50 into the coupling hole 12 of the connection member 10 in order, the inclined fixing protrusion of the fixing member 60 ( 61 is coupled to the connecting member 10 and the fixing member 60 by using the fastening member 80 or 100 in the state fitted in the rear of the locking piece (53).

이때 걸림편(53)과 기밀부(73)가 이루는 내경을 제외한 구성요소들의 내경은 끼워질 주름파이프(90)가 끼워질 수 있는 직경을 갖는다.At this time, the inner diameter of the components except the inner diameter formed by the engaging piece 53 and the airtight portion 73 has a diameter to which the pleated pipe 90 to be fitted.

이렇게 조립된 본 발명의 연결장치에 체결부재(80) 쪽에서 주름파이프(90)를 끼우게 되면 걸림편(53)은 주름파이프(90)가 끼워지는 반대방향으로 경사지게 형성되어 있기 때문에 외향으로 벌어졌다가 주름파이프(90)를 물어주게 되고, 기밀부(73)는 두께가 얇은 중간부위(72)와 일체로 제작되어 있기 때문에 뒤로 젖혀져 주름파이프(90)가 끼워지는데 지장을 주지 않으며 자체 탄성력에 의해 주름파이프(90)에 밀착됨으로써 기밀을 유지하는 역활을 한다.When the corrugated pipe 90 is inserted from the fastening member 80 in the connecting device of the present invention thus assembled, the locking piece 53 is formed to be inclined in the opposite direction to which the corrugated pipe 90 is fitted. The corrugated pipe 90 is queried and the airtight portion 73 is made integrally with the thin middle portion 72 so as to be rolled back so that the pleated pipe 90 does not interfere with the elastic force. As a result of being in close contact with the pleated pipe 90, it serves to maintain airtightness.

주름파이프(90)의 끝이 완전히 끼워지게 되면 주름파이프(90)의 끝부분이 패킹(20)의 기밀부(21)에 압착됨으로써 기밀이 완벽하게 유지되는 상태로 결합된다. 이때 고정부재(60)의 경사 고정돌부(61)는 걸림편(53)을 내부에서 지지함으로써 외력에 의해 주름파이프(90)가 후퇴하지 않도록 해주는 역할을 한다.When the end of the pleated pipe 90 is fully fitted, the end of the pleated pipe 90 is pressed to the airtight portion 21 of the packing 20 to be coupled in a state where the airtightness is completely maintained. At this time, the inclined fixing protrusion 61 of the fixing member 60 serves to prevent the corrugated pipe 90 from retreating by external force by supporting the locking piece 53 therein.

이와같이 본 발명은 작업자가 조립된 본 발명의 연결장치에 주름파이프(90)를 체결부재(80) 쪽에서 패킹(20)의 기밀부(21)에 압착되도록 밀어넣기만 하면 고정부재(60)에 의해 뒤로 밀려날 염려가 없는 걸림부재(50)와 체결부재(80)에 의해 주름파이프(90)가 연결장치에 견고히 결합될 뿐만 아니라 기밀부(21)에 의해 주름파이프(90)와 연결장치의 기밀상태가 완벽하게 유지될 수 있도록 한 효과가 있는 유용한 발명이다.As such, the present invention is provided by the fixing member 60 as long as the operator pushes the pleated pipe 90 to the airtight portion 21 of the packing 20 from the fastening member 80 side to the connection device of the assembled assembly. The corrugated pipe 90 is not only firmly coupled to the connecting device by the locking member 50 and the fastening member 80 without fear of being pushed back, and an airtight state of the corrugated pipe 90 and the connecting device by the airtight part 21. It is a useful invention that has the effect of keeping it perfectly.

이상에서는 본 발명을 첨부된 도면에 의거 한정하여 설명하였으나 여기에 한정되는 것은 아니며, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 다양한 변형이 가능함은 물론이다.The present invention has been described above with reference to the accompanying drawings, but is not limited thereto, and various modifications may be made without departing from the technical spirit of the present invention.
