Description

합성수지관의 연결구조{Pipe coupler and how to make it}Pipe coupler and how to make it}

본 발명은 합성수지관의 연결구조에 관한 것으로서, 더욱 상세하게는 연결하고자 하는 관들의 일측에 삽입관과 체결관을 용접 결합하여 상기 삽입관과 체결관의 끼움 결합으로 두 개의 관을 연결하는 것이다.The present invention relates to a connection structure of a synthetic resin pipe, and more particularly, to connect two pipes by fitting coupling of the insertion pipe and the fastening pipe by welding the insertion pipe and the fastening pipe to one side of the pipe to be connected.

합성수지관은 폴리프로필렌(PP), 폴리에틸렌(PE) 등 다양한 합성수지가 재료로 사용되어 오고 있고, 뛰어난 내식성으로 인해 수도관 등 주로 지하에 매설되어 사용되고 있다.Synthetic resin pipes have been used for various synthetic resins such as polypropylene (PP) and polyethylene (PE), and are mainly used underground in water pipes due to excellent corrosion resistance.

그런데, 이런 합성수지관을 연결해주기 위해서는 별도의 체결부재가 필요하며 주로 사용되는 것으로서는 특허 제527640호에 개시되어 있는 것이 있다.However, in order to connect such a synthetic resin tube, a separate fastening member is required, and the one mainly used is disclosed in Patent No. 527640.

상기 특허 제527640호에 개시되어 있는 하수관 연결구는 별도의 볼트와 너트로서 결합하여야하므로 그 작업이 번거로우며 부식 방지를 위해 알루미늄으로 몸체가 형성됨으로써 그 가격이 상승되는 문제가 있다.Since the sewer pipe connector disclosed in Patent No. 527640 has to be coupled as a separate bolt and nut, the work is cumbersome and the price is increased because the body is formed of aluminum to prevent corrosion.

또한, 볼트를 완전히 죄지 않으면 관 내부를 흐르는 물 등의 유체가 샐 우려가 있다.If the bolt is not tightened completely, fluid such as water flowing inside the pipe may leak.

따라서, 본 발명은 뛰어난 결합성으로 인해 한번 결합되고 나면 임의로 분리작업을 하지 않는 이상 분리되지 않음으로써 반영구적으로 사용이 가능한 합성수지관의 연결구조를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a connection structure of a synthetic resin tube that can be used semi-permanently by being separated once it is combined, because of the excellent bonding properties, unless it is arbitrarily separated.

또한, 합성수지관과 동일, 유사한 재질로서 삽입관과 체결관을 형성함으로써 가격이 저렴하며, 상기 삽입관과 체결관의 체결작업이 매우 용이한 합성수지관의 연결구조를 제공하는데 또 다른 목적이 있다.In addition, by forming an insertion tube and a fastening tube with the same material as the synthetic resin tube, the price is low, and there is another object to provide a connection structure of the synthetic resin tube is very easy to fasten the insertion tube and the fastening tube.

본 발명에 의한 합성수지관의 연결구조는 제1관과 용접에 의해 결합되며 절개부 및 걸림부가 형성되어 있는 삽입관과, 제2관과 용접에 의해 결합되며 상기 걸림부에 끼워지는 돌출부가 형성되어 있는 체결관으로 구성하며, 삽입관의 단부에 형성된 절개부에 의해 그 외경이 축소되면서 체결관에 삽입되고 체결된 후에는 그 탄성력에 의해 원래의 외경으로 복귀된다.The connection structure of the synthetic resin pipe according to the present invention is combined with the first tube by welding, the insertion tube is formed with an incision and the engaging portion, and the second tube is coupled by welding and the projection is fitted to the engaging portion is formed Consists of a fastening tube, and the outer diameter is reduced by the incision formed at the end of the insertion tube is inserted into the fastening tube and after being fastened to the original outer diameter by the elastic force.

본 발명에 의한 합성수지관의 연결구조는 뛰어난 결합성으로 인해 한번 결합되고 나면 임의로 분리작업을 하지 않는 이상 분리되지 않음으로써 반영구적으로 사용이 가능하며, 합성수지관과 동일, 유사한 재질로서 삽입관과 체결관을 형성함으로써 가격이 저렴하고, 상기 삽입관과 체결관의 체결작업이 매우 용이하다.The connection structure of the synthetic resin tube according to the present invention can be used semi-permanently because it is not separated unless the separation operation is arbitrarily performed once, due to its excellent bonding properties, and the same material as the synthetic resin tube, and insert tube and fastening tube By forming a low price, the fastening operation of the insertion pipe and the fastening pipe is very easy.

본 발명은 합성수지관의 연결구조에 관한 것으로서, 더욱 상세하게는 연결하고자 하는 관들의 일측에 삽입관(10)과 체결관(20)을 용접 결합하여 상기 삽입관(10)과 체결관(20)의 끼움 결합으로 두 개의 관을 연결하는 것이다.The present invention relates to a connection structure of a synthetic resin pipe, and more particularly, the insertion pipe 10 and the fastening pipe 20 by welding coupling to one side of the pipe to be connected to the insertion pipe 10 and the fastening pipe 20 The fitting of the two will connect the two pipes.

이하, 첨부된 도면에 의해 본 발명의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention by referring to the accompanying drawings in detail as follows.

도 1은 본 발명의 구성예시도이고, 도 2는 도 1의 A-A섹션 단면도이며, 도 3은 본 발명의 분리구성예시도로서, 본 발명에 의한 합성수지관의 연결구조는 두 개의 관을 연결하기 위한 구조에 있어서, 제1관(1)과 용접에 의해 결합되며 절개부(11) 및 걸림부(12)가 형성되어 있는 삽입관(10)과, 제2관(2)과 용접에 의해 결합되며 상기 걸림부(12)에 끼워지는 돌출부(21)가 형성되어 있는 체결관(20)으로 구성되어 있다.Figure 1 is a schematic view of the configuration of the present invention, Figure 2 is a cross-sectional view of the AA section of Figure 1, Figure 3 is a separate configuration of the present invention, the connection structure of the synthetic resin tube according to the present invention to connect two pipes In the structure for, the first pipe 1 is coupled by welding and the insertion pipe 10 is formed with a cutout portion 11 and the locking portion 12, the second pipe 2 and coupled by welding It is composed of a fastening tube 20 is formed with a projection 21 to be fitted to the engaging portion 12.

미설명부호는 요홈(13) 및 고무링(14)이다.Reference numerals are grooves 13 and rubber rings 14.

상기 절개부(11)는 삽입관(10)의 원주면을 따라 하나 이상 방사형으로 형성되어 있으며, 상기 돌출부(21)는 삽입관(10)의 걸림부(12)에 억지 끼움되어 결합 후 임의로 분리되지 않는다.The cutout 11 is formed at least one radially along the circumferential surface of the insertion tube 10, the protrusion 21 is forcibly fitted to the engaging portion 12 of the insertion tube 10 is separated after coupling arbitrarily It doesn't work.

상기 삽입관(10)의 원주면에는 요홈(13)이 형성되며 상기 요홈(13)에 고무링(14)이 결합되어 기밀이 유지됨으로써 관 내부를 흐르는 유체가 외부로 새지 않는다.Grooves 13 are formed on the circumferential surface of the insertion tube 10 and the rubber ring 14 is coupled to the grooves 13 so that airtightness is maintained so that the fluid flowing inside the tube does not leak to the outside.

여기서, 상기 제1, 2관과 삽입관(10) 및 체결관(20)의 용접은 관의 재질과 동일하거나 유사한 재료를 녹여 용융접착하는 것이 바람직한데, 경우에 따라 접착제나 볼트, 너트 등의 결합부재를 사용할 수도 있다.Here, the welding of the first, the second tube and the insertion tube 10 and the fastening tube 20 is preferably melted and melted the same or similar materials as the material of the tube, in some cases, such as adhesives, bolts, nuts, etc. Coupling members may also be used.

상기 삽입관(10)에는 복수의 절개부(11)가 형성되어 있는데, 상기 절개부(11)는 삽입관(10)이 체결관(20)에 끼워질 때 그 간격이 줄어들게 되어 결국 삽입관(10)의 외경이 줄어들게 된다.The insertion tube 10 has a plurality of incisions 11 are formed, the incision portion 11 is reduced when the insertion tube 10 is fitted to the fastening tube 20, the end of the insertion tube ( 10) will reduce the outer diameter.

상기 삽입관(10)이 체결관(20)에 끼워지게 되면 도 4 및 도 5와 같은 상태가 되는데, 체결관(20)의 돌출부(21)에 삽입관(10)의 걸림부(12)가 끼워져 임의로 분리되지 않는 상태가 된다.When the insertion tube 10 is fitted to the fastening tube 20, the state as shown in Figs. 4 and 5, the locking portion 12 of the insertion tube 10 to the protrusion 21 of the fastening tube 20 It is in a state where it is inserted and cannot be arbitrarily separated.

즉, 삽입관(10)이 체결관(20) 내로 억지 끼움식으로 끼워질 때 돌출부(21)에 의해 그 외경이 줄어들면서 밀려 들어가고 걸림부(12)를 지나고 나면 합성수지관의 탄성력에 의해 그 외경이 원래의 상태대로 확장되어 임의로 분리되지 않는 상태가 된다.That is, when the insertion tube 10 is pushed into the fastening tube 20, the outer diameter is pushed down by the protrusion 21, and after passing through the locking portion 12, the outer diameter by the elastic force of the synthetic resin tube This is expanded to its original state, and the state is not separated.

또한, 상기 돌출부(21)의 형상이 위로 볼록한 모양이므로 걸림부(12)가 형성된 삽입관(10)이 더욱 빠지지 않게 된다.In addition, since the shape of the protruding portion 21 is convex upward, the insertion tube 10 in which the locking portion 12 is formed does not fall further.
