이러한 목적을 달성하기 위해 본 고안의 일실시예에 따른 플라스틱관 결합 구조는, 제1플라스틱관과 제2플라스틱관을 연통되고 기밀되게 연결시키기 위한 플라스틱관 결합 구조에 있어서, 제1플라스틱관의 제조과정중 관형성후, 고온에서 절단즉시 제1플라스틱관의 연결단부 내경측으로 삽입되고, 냉각시 열수축에 의해 그 제1플라스틱관의 열수축결합부에 압착,고정되는 관압착부와, 제2플라스틱관이 내측으로 삽입되어 패킹링홈 및 패킹링을 개재하여 기밀되게 연결되는 관삽입부와, 그 관삽입부를 내측단부에서 관압착부의 외측단부로 연결시키는 환상연결부를 포함하여 구성되는 것을 특징으로 한다.Plastic pipe joint structure according to an embodiment of the present invention to achieve this purpose, in the plastic pipe joint structure for connecting the first plastic pipe and the second plastic pipe in a hermetic and hermetic seal, the manufacture of the first plastic pipe After the formation of the pipe during the process, the tube is crimped and inserted into the inner diameter side of the connection end of the first plastic pipe immediately at high temperature, and pressed and fixed to the heat-shrink joint of the first plastic pipe by heat shrinking during cooling, and the second plastic pipe.

For this purpose, the inlet enlargement part is preferably formed at the outer end of the tube insertion part.
이하, 첨부된 도면을 참조하여 본 고안의 바람직한 실시예(들)를 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiment (s) of the present invention will be described in detail with reference to the accompanying drawings.
도 1a 및 도 1b에는 본 고안의 일실시예에 따른 플라스틱관 결합 구조의 결합전 분리단면도가 도시되고, 도 2a 및 도 2b에는 그 결합상태를 나타내는 일부단면도가 도시된다. 도 1a와 도 2a는 금속제로 가공된 경우의 일예이고 도 1b와 도 2b는 합성수지로 사출,가공된 경우의 일예이다.1A and 1B show a cross-sectional view of a plastic pipe coupling structure before coupling according to an embodiment of the present invention, and FIGS. 2A and 2B show a partial cross-sectional view showing a coupling state thereof. Figures 1a and 2a is an example of the case of metal processing and Figures 1b and 2b is an example of the case of injection, processing with synthetic resin.
도 1a 및 도 1b와 도 2a 및 도 2b에서 결합부재(10)는, 관압착부(11), 관삽입부(12) 및 환상연결부(16)로 구성된다. 그 관압착부(11)는, 대개 소경부로서 제1플라스틱관(1)의 제조과정중 관형성후, 고온에서 절단즉시, 도 3에 도시된 바와 같이, 제1플라스틱관(1)의 연결단부 내경측으로 삽입되고, 냉각시 열수축에 의해 그 제1플라스틱관(1)의 열수축결합부(1a)에 압착,고정된다.In FIGS. 1A and 1B and FIGS. 2A and 2B, the coupling member 10 includes a tube crimping unit 11, a tube inserting unit 12, and an annular connector 16. The tube crimping part 11 is a small diameter part, which is usually cut at a high temperature immediately after forming the tube during the manufacturing process of the first plastic pipe 1, and as shown in FIG. 3, the connection of the first plastic pipe 1. It is inserted into the end inner diameter side, and is compressed and fixed to the heat shrinkage coupling portion 1a of the first plastic pipe 1 by heat shrinkage during cooling.
관삽입부(12)는, 제2플라스틱관(2)이 내측으로 삽입되어 패킹링홈 (15) 및 패킹링(20)을 개재하여 기밀되게 연결된다. 그 관삽입부(12)는, 도면에서와 같이 동일한 직경의 관을 연결시키기 위해서는 관압착부(11)보다 약간 큰 직경으로 형성되어 결합부재(10)가 2단 관형상이지만, 제1플라스틱관(1) 및 제2플라스틱관(2)의 관경에 따라 단이 없는 경우도 가능할 것이다.The tube inserting portion 12, the second plastic tube 2 is inserted into the inside is hermetically connected via the packing ring groove 15 and the packing ring 20. The tube insert 12 is formed with a diameter slightly larger than the tube crimp 11 so as to connect tubes of the same diameter as shown in the drawing, the coupling member 10 is a two-stage tubular shape, but the first plastic tube Depending on the diameters of (1) and the second plastic pipe (2), it may be possible to have no stage.
환상연결부(16)는, 관압착부(11)의 외측단부를 관삽입부(12)의 내측단부에 연결시키도록 구성된다.The annular connecting portion 16 is configured to connect the outer end of the tube crimping portion 11 to the inner end of the tube inserting portion 12.
이러한 결합부재(10)는, 플라스틱제로 형성되는 것이 비용면에서 저렴하다.강도를 요하는 경우 열수축에 의한 압착 및 강도면에서 금속제로 형성되는 것이 바람직하다. 도 1a와 도 2a에서와 같이 금속제의 경우, 스피닝가공법 등에 의해 용이하게 제조될 수 있다.The coupling member 10 is made of plastic, which is inexpensive. In the case of requiring strength, the coupling member 10 is preferably made of metal in terms of compression and strength due to heat shrinkage. In the case of a metal, as shown in Figure 1a and 2a, it can be easily produced by a spinning process or the like.
상술한 바와 같이 플라스틱관 결합 구조가 구성됨으로써 결합부재(10)의 제조가 용이할 뿐만 아니라, 결합부재(10)의 관압착부(11)를 용이하게 제1플라스틱관(1)의 열수축결합부(1a)에 고강도로 기밀되게 압착결합시킬 수 있으며, 이때, 관압착부(11)의 내경을 수축될 제1플라스틱관(1)의 내경과 동일하게 하더라도 열수축결합부(1a)가 관압착부(11)의 두께만큼 확장된 상태로 수축냉각되게 되어 유량의 손실은 거의 발생하지 아니하게 된다.Since the plastic pipe coupling structure is configured as described above, not only the manufacturing of the coupling member 10 is easy, but also the heat shrinkable coupling portion of the first plastic pipe 1 facilitates the pipe crimping portion 11 of the coupling member 10. (1a) can be press-bonded with high strength and airtight, and at this time, even if the inner diameter of the tube crimping portion (11) is the same as the inner diameter of the first plastic pipe (1) to be shrunk, the heat shrinkable coupling portion (1a) Shrinkage cooling in the state extended by the thickness of (11) causes almost no loss of flow rate.
또, 관삽입부(12)는 제2플라스틱관(2)의 외경이 패킹링(20)을 개재하여 삽입되는 직경으로 제2플라스틱관(2)의 삽입이 용이할 뿐만 아니라, 패킹링(20)에 의해 고강도로 기밀되게 된다.In addition, the tube inserting portion 12 is a diameter in which the outer diameter of the second plastic tube 2 is inserted through the packing ring 20, and the insertion of the second plastic tube 2 is not only easy, but also the packing ring 20 ) Is hermetically sealed with high strength.
이와 같이 하여 제1플라스틱관(1)과 제2플라스틱관(2)은 거의 유량이나 압력의 손실없이 연통되고 기밀되게 연결되게 된다.In this way, the first plastic pipe 1 and the second plastic pipe 2 are connected in an airtight and hermetic connection with almost no loss of flow rate or pressure.
또, 단을 형성하는 환상연결부(16)에 의해 제1플라스틱관(1) 및 제2플라스틱관(2)의 삽입되는 양이 정해지게 되어 연결작업이 편리하게 된다.In addition, the amount of insertion of the first plastic pipe 1 and the second plastic pipe 2 is determined by the annular connecting portion 16 forming the stage, so that the connection work is convenient.
또한, 도1 내지 도 3에서와 같이 외측환상돌기(14)가 관압착부(11)의 외주에 형성됨으로써 제1플라스틱관(1)의 열수축결합부(1a)에의 압착력을 강화시키게 되고 더욱 강한 인출력에 의해서도 이탈을 방지시킬 수 있게 된다.In addition, as shown in FIGS. 1 to 3, the outer annular protrusion 14 is formed on the outer circumference of the tube crimping portion 11, thereby enhancing the compressive force of the first plastic pipe 1 to the heat shrinkage coupling portion 1a and becoming stronger. The departure can be prevented by the output.
더욱, 도 1 내지 도 3에 도시된 바와 같이, 입구확대부(13)가 관삽입부(12)의 외측단부에 형성됨으로써 제2플라스틱관(2)의 삽입을 더욱 용이하게 하여 조립 및 결합작업이 쉽게 이루어질 수 있으며, 현장에서의 시공도 간단하게 이루어질 수 있게 된다.Further, as shown in Figures 1 to 3, the inlet enlarged portion 13 is formed on the outer end of the tube inserting portion 12 to facilitate the insertion of the second plastic tube (2) for assembling and coupling work This can be done easily, construction in the field can be made simply.
또한, 도 1b와 도 2b에 도시된 실시예에서와 같이, 경사돌출부(15a)가 관축방향으로 다수 관삽입부(12) 내벽에 형성되고, 그 경사돌출부(15a)에 패킹링홈(15)이 형성되는 것이 제2플라스틱관(2)의 삽입을 용이하게 할 수 있어 바람직하다. 또, 그 패킹링홈(15)에 삽입되는 패킹링(20)은, 대략 ㄷ자단면형상의 패킹링(20)인 것이 제2플라스틱관(2)의 삽입을 더욱 용이하게 하고, 더욱 이탈을 방지할 수 있어 바람직하다.In addition, as in the embodiment shown in Figs. 1b and 2b, the inclined protrusion 15a is formed in the inner wall of the plurality of pipe inserts 12 in the tube axis direction, and the packing ring groove 15 is formed in the inclined protrusion 15a. It is preferable to be formed because it can facilitate the insertion of the second plastic pipe (2). In addition, the packing ring 20 inserted into the packing ring groove 15 is a packing ring 20 having a substantially c-shaped cross section, which facilitates the insertion of the second plastic pipe 2 and further prevents the separation thereof. It is preferable to be able.
이상에서 설명한 본 고안의 실시예에 따른 플라스틱관 결합 구조의 구성과 작용에 의하면, 용이하게 제작할 수 있는 간단한 구조의 결합부재를 더욱 용이하게 플라스틱관의 제작과정에서 기밀되게 장착 내지 조립할 수 있으며, 나아가, 플라스틱관의 연결작업도 간단하게 이루어질 수 있고, 연결후 연결강도 및 기밀강도가 우수하게 되는 등의 효과가 있다.According to the configuration and operation of the plastic pipe coupling structure according to the embodiment of the present invention described above, the coupling member of a simple structure that can be easily manufactured can be more easily mounted or assembled in the manufacturing process of the plastic pipe, , The connection work of the plastic pipe can also be made simply, and the connection strength and hermetic strength are excellent after the connection.
