본 고안은 연결관을 사용하여 나선들을 서로 접촉연결할때 접속부위의 기밀성을 유지하기 위해 사용되는 나선관 연결용 패킹에 관한 것이다.The present invention relates to a packing for a spiral pipe connection used to maintain the airtightness of the connection when connecting the spirals in contact with each other using a connection pipe.

종래에는 나선관들을 서로 접속연결함에 있어 나선관의 외주에 요설되어있는 나선홈에다 합성수지나 기타재질로된 로우프등을 적당한 길이로 감아서 메꾸어 놓고 다시 그위에 접착제를 도포시켜준뒤 연결관을 끼워서 서로 연결된 나선관의 접속부위에 기밀성을 부여하였던 것이다. 그러나 이는 나선관과 연결관 간의 감합을 밀접시키지 않으면 접착제에 의한 봉합(封合)이 완벽하게 되지 않는 것이어서 관의 접합부분에서 누설이 빈번하게 되었고, 나선관과 연결관 간의 나합에도 힘이 들어서 그 연결작업에 많은 노력과 시간이 요구되는 등의 문제점이 있는 것이었다.Conventionally, in connecting the spiral pipes to each other, wrap the spiral grooves on the outer circumference of the spiral pipes with a suitable length of a rope made of synthetic resin or other materials, and then fill them up, and then apply an adhesive thereon, and then insert the connectors together. Airtightness was given to the connecting part of the connected spiral tube. However, if the fitting between the spiral tube and the connecting tube is not close, the sealing by the adhesive is not perfect and leakage occurs frequently at the joint portion of the tube. There was a problem that it takes a lot of effort and time to connect.

또한 이와같은 문제점을 해결하기 위한 것으로, 제4도에서 도시하고 있는 바와 같이 나선관(1)(1')의 외주에 나합케되는 연결관(2)이 비교적 큰 틈새를 갖고 나합되게 하고, 그 틈새에 합성수지제 발포물(a)을 충진시켜서 충진된 발포물(a)에 의해 나선관(1)(1')과 연결관(2)간의 결합강도를 강화시키는 동시에 완전한 기밀성이 유지되도록 하는 것도 있으나, 이는 발포물(a)을 틈새에 충진함에 있어 연결관(2)의 적당한 수개소에 발포물주입구멍을 뚫어서 이를 통해 발포물(a)을 충진시켜야 되는등 그 조립작업이 번거롭고 연결관(2)의 자체강도를 약화시키는 결과를 초래케되었으며, 발포물(a)의 충진상태도 균일하지 않게 될 우려가 있고 이렇게 될 경우 관접속부위의 완벽한 기밀성을 유지하지 못하는 문제가 따르는 것이었다.In addition, to solve such a problem, as shown in FIG. 4, the connecting pipe 2, which is screwed to the outer circumference of the spiral pipe 1, 1 ', has a relatively large gap and is screwed together. Filling the gap with a synthetic resin foam (a) to enhance the bond strength between the spiral tube (1) (1 ') and the connecting tube (2) by the filled foam (a) to maintain a complete airtightness However, this is cumbersome in assembling work such as having to fill the foam (a) through a hole in the foam injection hole in the appropriate place of the connection pipe (2) in filling the gap in the gap (2) and the connection pipe (2). This resulted in the weakening of its own strength, and the filling state of the foam (a) could be uneven, and in this case, the airtightness of the joint was not maintained.

본 고안은 이와같은 종래의 문제점들을 해결하여 나선관을 서로 연결 접속시킴에 있어 그 접속부위의 완벽한 기밀성을 얻을 수 있는 패킹을 제공함에 그 목적이 있는 것이다.The present invention aims to provide a packing which can solve the conventional problems and obtain perfect airtightness of the connection part in connecting the spiral pipes to each other.

본 고안의 내용을 첨부도면에 의거 상세히 설명하면 다음과 같다. 즉, 연결관(2)의 의하여 서로 연결접속되는 나선관(1)(1')의 기밀유지를 위한 패킹(3)을 형성함에 있어, 양측단에 걸림턱(3a')이 절곡형성된 감합대(3a)의 양선단을 서로 어긋나게하여 그 사이에 나합돌출부(3b)를 일체로 연설시켜서 감합대(3a)가 나선형을 이루도록 구성하여 되는 나선관 연결용 패킹인 것이다.Referring to the contents of the present invention in detail based on the accompanying drawings as follows. That is, in forming the packing (3) for the airtightness of the spiral pipe (1) (1 ') is connected to each other by the connecting pipe (2), the fitting table is formed in the engaging jaw (3a') bent at both ends It is a helical pipe connecting packing configured to align the two ends of (3a) with each other and to make the fitting protrusion 3a spiral so as to integrally propagate the screwing projections 3b therebetween.

본 고안의 실시에 있어서 도면 제3(a)도에서와 같이, 감합대(3a)의 상면 중앙에 돌기부(3a'')를 일체로 형성하여 패킹의 기밀성이 보다 향상되도록 구성할 수 있는 것이며, 제3(b)도에서와 같이 감합대(3a)의 상면에다 일측이 경상면으로된 다수개의 돌기부(3a''')를 나란히 일체로 형성할 수도 있는 것이다.In the implementation of the present invention, as shown in FIG. 3 (a), the protrusion 3a '' may be integrally formed at the center of the upper surface of the fitting table 3a, so that the airtightness of the packing may be further improved. As shown in FIG. 3 (b), a plurality of protrusions 3a '' 'having one side as a mirror surface may be integrally formed side by side on the upper surface of the fitting table 3a.

본 고안의 사용상태를 설명하면 먼저 상호 접속연결을 요하는 나선관(1)(1')의 접속단부(1a)(1a')로부터 일정한 거리에 위치되는 나선홈(1b)에 패킹(3)의 나합돌출부(3b)가 끼워지고 감합대(3a)의 양측단 걸림턱(3a')은 나선관(1)(1')의 나선돌출부(1c)에 씌워져 걸린 상태로 감합되도록한뒤 이를 연결관(2)의 양단개구부를 통하여 각기 삽입시켜서 나합전진시켜주게되면 패킹(30)이 나선관(1)(1')과 함께 연결관(2)의 활면부(2')를 타고 전진되다가 패킹지지턱(2a)에 닿게 되면서 나선관(1)(1')의 전진이 중지케됨과 동시에 나선관(1)(1')의 접속단부(1a)(1a')는 연결관(2)의 중심위치에서 서로 접속연결케되고, 패킹(3)은 패킹지지턱(2a)과 활면부(2')에 의해 가압지지되면서 완벽한 기밀성을 유지하게 되는 것이다.When explaining the state of use of the present invention, the packing (3) in the spiral groove (1b) which is located at a constant distance from the connecting end (1a) (1a ') of the spiral tube (1) (1') that requires interconnection connection Screwed projections 3b of the fittings are fitted, and both ends of the locking jaw 3a 'of the fitting table 3a are covered with the screwed projections 1c of the spiral tube 1, 1' to be fitted in a jammed state and then connected thereto. After inserting through both ends of the pipe (2) to advance each other, the packing (30) is advanced along the spiral surface (2 ') of the connecting pipe (2) together with the spiral pipe (1) (1') and then packed As it comes into contact with the support jaw 2a, the forward movement of the spiral tube 1, 1 'is stopped and at the same time, the connecting end 1a, 1a' of the spiral tube 1, 1 'is connected to the It is connected to each other at the center position, the packing (3) is to be pressed by the packing support jaw (2a) and the smooth surface portion (2 ') to maintain complete airtightness.

본 고안은 상술한 바와같이 패킹을 구성하는 감합대가 나선형을 이루고 있고 그사이에 나합돌출부가 일체로 형성되어 있는 것이어서 접착제등을 사용할 필요없이 이를 나선관의 접속단부로 부터 나합전진시켜서 패킹이 부설될 위치를 조절하기가 용이한 것이므로 연결관의 길이에 따라 이를 간편히 조절고정하여 연결된 나선관의 기밀성을 완벽하게 유지시켜 주게 되는 매우 유용한 효과를 제공하게 되는 것이다.As described above, the fitting band constituting the packing is spirally formed as described above, and the screwing protrusion is integrally formed therebetween, so that the packing is laid by advancing it from the connecting end of the spiral pipe without using an adhesive or the like. Since it is easy to adjust the fixed length according to the length of the connecting pipe is to provide a very useful effect that keeps the tightness of the connected spiral pipe perfectly.
