상수관, 하수관 등 각종 관으로 사용되는 PE(Polyethylene)관 등 합성수지관체를 수밀되게 연결시키는 관 연결구는 다수 개의 합성수지관체를 일렬로 배열하고, 맞닿는 단부를 안정되게 일직선으로 연결시켜 높은 직선도를 유지하면서 수밀이 이루어지도록 하는 기구이다.Pipe connector that tightly connects synthetic resin pipes such as PE (Polyethylene) pipes used for various pipes such as water pipes and sewage pipes arranges a number of synthetic resin pipes in a row and maintains a high straightness by stably connecting the end parts in contact with each other. It is a mechanism that ensures watertightness.

이와 같은 관 연결구의 기본적인 구조는 둥글게 감겨진 체결밴드와; 상기 체결밴드의 양단부에 설치되고, 체결밴드의 감긴 방향과 반대 방향인 외측으로 둥글게 감기며, 다수 개의 결합공이 뚫린 압지편장착대와; 상기 압지편장착대에 결합되게 설치되되 상기 결합공과 통하도록 형성된 볼트삽입공이 형성된 압지편과; 상기 볼트공과 볼트삽입공에 끼워져 너트로 체결되어 체결밴드를 조여주는 볼트;로 구성된다.The basic structure of such a tube connector is round fastening band wound; Installed on both ends of the fastening band, and wound around the outer side of the fastening band in a direction opposite to that of the fastening band, and a plunger piece mounting hole having a plurality of coupling holes; A blotting piece installed to be coupled to the blotting piece mounting stand and having a bolt insertion hole formed to communicate with the coupling hole; The bolt is inserted into the bolt and the bolt insertion hole is fastened with a nut to tighten the fastening band; consists of.

상기와 같은 종래 관 연결구의 구조에서는, 볼트를 체결밴드의 양단에 설치된 압지편장착대에 체결된 압지편의 볼트삽입공에 끼운 후 너트로써 조여주게 된다. 이 때 체결밴드가 조여짐에 따라 그 직경이 작아지게 되는데 직경이 변화되어감에 따라 압지편의 볼트삽입공의 방향이 변하게 된다. 따라서 볼트삽입공에 삽입된 볼트가 굽힘력을 받게 되고, 이에 의한 저항에 의해 체결밴드가 완전하게 관을 이음할 수 없게 되고, 이로써 수밀이 저하되는 문제가 있다.In the structure of the conventional pipe connector as described above, the bolt is inserted into the bolt insertion hole of the blotting piece fastened to the blotting piece mounting table installed on both ends of the fastening band and tightened with a nut. At this time, as the fastening band is tightened, the diameter thereof decreases. As the diameter changes, the direction of the bolt insertion hole of the blotter piece changes. Therefore, the bolt inserted into the bolt insertion hole receives a bending force, and thus the fastening band cannot completely join the pipe due to the resistance, thereby causing a problem in that the watertightness is reduced.

따라서 본 발명은 체결밴드를 볼트로써 조여줄 때 체결밴드의 직경이 변화하더라도 볼트가 직진성을 그대로 유지할 수 있도록 압지편이 회동되는 구조를 제공 함에 목적이 있다.Therefore, an object of the present invention is to provide a structure in which the blotting piece is rotated so that the bolt can maintain the straightness even when the diameter of the fastening band is changed when tightening the fastening band with the bolt.

상기의 목적을 달성하기 위하여 압지편이 압지편장착대에서 회전될 수 있도록 압지편에 형성된 결합돌기를 압지편장착대에 형성된 결합공의 상하 폭보다 작게 하여 결합돌기가 결합공에 체결된 상태에서 상하로 움직일 수 있도록 하는 구조를 제공한다. 그리고 보다 확실한 수밀을 위하여 패드에 형성된 수밀돌조의 구조를 두께가 큰 것 한 개와 두께가 작은 다수 개로 형성시킨 수밀성이 향상된 관 연결구를 제공하게 된다.In order to achieve the above object, the upper and lower sides of the engaging projection formed in the crushing piece mounting bracket is smaller than the upper and lower widths of the engaging holes formed in the crushing piece mounting bracket so that the tacking piece can be rotated in the tacking piece mounting bracket. It provides a structure that allows it to move around. In order to ensure more water tightness, it is possible to provide a water-tightness pipe joint formed by forming a watertight protrusion formed on the pad in one of a large thickness and a plurality of small thicknesses.

본 발명에 따르면, 관 연결구를 관의 인접된 단부에 부착하여 볼트로써 체결밴드를 조일 때 발생되는 체결밴드의 작경 변화에 따라 볼트가 굽힘력을 받지 않도록 볼트를 체결하고 있는 압지편이 회전을 하게 됨으로써, 볼트의 굽힘에 의해 체결밴드가 제대로 관을 수밀되게 이음하지 못하였던 종래의 문제점을 해소하게 된다.According to the present invention, by attaching the pipe connector to the adjacent end of the tube to tighten the fastening band with a bolt, the blotting piece fastening the bolt so that the bolt is not subjected to bending force in accordance with the change in the diameter of the fastening band generated by By the bending of the bolt, the conventional band can not solve the conventional problem that the fastening band was not tightly seam tightly.

그리고 수밀돌조를 굵은 것과 얇은 것의 다중 구성을 함으로써, 얇은 것에 의해 세밀한 수밀이 이루어지고, 굵은 것에 의한 수압을 견디는 이중 효과에 의해 보다 확실한 수밀이 이루어지게 된다.And by making a watertight roughening multiple structure of a thick and a thin thing, fine watertightness is achieved by thinness, and more reliable watertightness is achieved by the double effect which withstands the water pressure by coarseness.

관 연결구(100)는 관(50)을 감싸도록 둥글게 포개지도록 감겨진 체결밴드(1); 상기 체결밴드(1)의 감겨진 방향의 양측부에 각각 나란히 설치되고, 일정 간격으로 압지편(2)이 삽입되는 삽입홈(3)이 둥글게 형성된 압지편장착대(4); 상기 체결밴드(1)의 내부에 설치된 패드(5); 상기 각각의 압지편장착대(4)의 삽입홈(3)에 삽입되어 체결되고, 볼트삽입공(6)이 관통되며, 볼트삽입공(6)의 일측부에 결합돌기(7)가 형성된 압지편(2); 상기 마주보는 압지편(2)의 볼트삽입공(6)을 관통하여 고정시키는 볼트(8) 및 너트(9);를 포함하여 구성된다.Pipe connector 100 is fastening band (1) wound so as to surround the tube 50 roundly; A press-fit piece mounting table 4 having side-by-side portions of the fastening band 1 which are respectively installed in parallel with each other and having insertion grooves 3 into which the press-piece pieces 2 are inserted at regular intervals; A pad 5 installed in the fastening band 1; The blotter paper which is inserted into and fastened to the insertion grooves 3 of the respective blotting piece mounting brackets 4, and the bolt insertion holes 6 penetrate through the coupling protrusions 7 formed at one side of the bolt insertion holes 6. Section (2); And a bolt (8) and a nut (9) for penetrating and fixing the bolt insertion hole (6) of the opposing press piece (2).

본 발명은 상기의 압지편장착대(4)에 형성된 삽입홈(3)이 도 1과 같이 상하 방향으로 길게 형성된 구조이고, 상기 결합공(10)에 결합되는 압지편(2)의 결합돌기(7)는 결합공(10)에 결합된 상태에서 상하로 움직일 수 있도록 결합공(10)의 상하 폭보다 작은 상하 두께로 되어 있음에 특징이 있다.The present invention has a structure in which the insertion groove (3) formed in the blotting piece mounting table (4) is formed long in the vertical direction as shown in Figure 1, the engaging projection of the blotting piece (2) coupled to the coupling hole 10 ( 7) is characterized in that the upper and lower thickness is smaller than the vertical width of the coupling hole 10 to move up and down in the state coupled to the coupling hole (10).

그리고 수밀성을 향상시키기 위하여 둥글게 감긴 상기의 체결밴드(1)의 내측면, 즉 관(50)과 접촉되는 부분에 수밀돌조(11)가 형성된다. 특히 본 발명에서의 수밀돌조(11)는 도 5에 도시된 바와 같이, 두꺼운 돌조(12)와 하나 이상의 얇은 돌조(13)로 구성된다.In order to improve the watertightness, the watertight protrusion 11 is formed on the inner surface of the fastening band 1 that is roundly wound, that is, the part that is in contact with the tube 50. In particular, the watertight protrusion 11 in the present invention is composed of a thick protrusion 12 and one or more thin protrusions 13, as shown in FIG.

이와 같은 구조는 다수 개의 짧은 압지편(2) 또는 긴 하나의 압지편(2)이 개구된 삽입홈(3)에 삽입되어 관(50)을 연결하는 구조로서 도 1에 전체 사시도가 도시되어 있고, 도 2에 그 단면이 도시되어 있다. 그리고 도 3에 본 발명의 특징적인 부분으로서 볼트(8)가 회동될 수 있는 구조가 도시되어 있고, 도 4에 도 3의 "A-A" 부 단면이 도시되어 있으며, 도 5에 본 발명의 또 다른 특징인 패드(5)의 단면이 도시되어 있다.Such a structure is a structure in which a plurality of short tack pieces (2) or one long tack piece (2) is inserted into the insertion groove (3) that is opened to connect the pipe (50) as shown in FIG. 2, its cross section is shown. 3 shows a structure in which the bolt 8 can be rotated as a characteristic part of the present invention, a section “AA” of FIG. 3 is shown in FIG. 4, and another embodiment of the present invention in FIG. 5. A cross section of the pad 5 is shown.

관 연결구(100)는 체결밴드(1)의 내측에 패드(5)를 덧댄 후 도 5와 같이 관(50)의 연결부위를 밀폐시키도록 설치된다. 따라서 관(50) 연결부에 장착한 후 압지편장착대(4)에 압지편(2)을 설치하고, 서로 짝을 이루는 압지편(2)에 볼트(8)를 관통시켜 체결한 후 너트(9)로써 조여 고정하면 된다.Pipe connector 100 is installed so as to seal the connecting portion of the tube 50 as shown in Figure 5 after the pad 5 to the inside of the fastening band (1). Therefore, after attaching to the pipe 50, the tack piece (2) is installed on the tack piece mounting base (4), and the bolt (8) is fastened through a pair of tack pieces (2) mating with each other after the nut (9) Tighten with).

이와 같은 작업시에 볼트(8)와 너트(9)로써 짝을 이루는 압지편(2) 사이의 간격을 줄여 조여주면, 둥근 관(50)에 의해 압지편(2)의 볼트삽입공(6)의 방향이 점진적으로 변하게 된다.In such a work, if the gap between the squeezing piece 2 paired with the bolt 8 and the nut 9 is reduced and tightened, the bolt insertion hole 6 of the squeezing piece 2 is rounded by the round tube 50. The direction of changes gradually.

종래의 경우 상기와 같은 볼트삽입공(6)의 방향이 변화하는 이유로, 볼트(8)에 굽힙력이 방생하였고, 이로 인해 단단히 조여줄 수 없었다. 그러나 본 발명은 볼트삽입공(6)의 방향이 변화하더라도 짝은 이루는 압지편(2)의 볼트삽입공(6) 들은 직선을 이루도록 하여, 볼트(8)가 휘어지는 힘이 발생되지 않게 된다. In the conventional case, the bending force is generated in the bolt 8 due to the change of the direction of the bolt insertion hole 6 as described above, and thus, it cannot be tightened firmly. However, in the present invention, even if the direction of the bolt insertion hole 6 changes, the bolt insertion holes 6 of the pair of blotting pieces 2 form a straight line so that the force of bending the bolt 8 is not generated.

이와 같은 효과는 압지편(2)이 회전될 수 있는 구조에 의한 것으로, 도 3에 도시된 바와 같이, 압지편(2)에 형성된 결합돌기(7)가 압지편장착대(4)에 형성된 결합공(10)에 삽입되어 체결되되, 결합돌기(7)의 상하 폭이 결합공(10)의 상하 폭보다 작기 때문이다. 따라서 압지편(2)의 간격이 좁아지면서 압지편(2)의 볼트삽입공(6)의 방향이 달라지려 하면, 볼트삽입공(6)에 삽입된 볼트(8)의 강성에 의하여 압지편(2)이 회전되면서 볼트삽입공(6)은 직선을 이룰 수가 있게 된다.This effect is due to the structure that the tack piece 2 can be rotated, as shown in Figure 3, the engaging projection 7 formed on the tack piece 2 is formed in the tack piece mounting table 4 Is inserted into the ball 10 is fastened, because the upper and lower width of the engaging projection 7 is smaller than the upper and lower width of the coupling hole (10). Therefore, when the distance between the tack pieces 2 is narrowed and the direction of the bolt insertion holes 6 of the tack pieces 2 is to be changed, the tack pieces (the stiffness of the bolts 8 inserted into the bolt insertion holes 6) As the 2) is rotated, the bolt insertion hole 6 can form a straight line.

상기의 결합돌기(7)의 단부에는 돌기가 형성되어 있어, 결합공(10)에 삽입되 면 쉽게 빠지지않는 구조로 되어 있다. 그러나 움직일 수 있음은 상기에서 살펴본 바와 같다.Protrusions are formed at the ends of the coupling protrusions 7, and are inserted into the coupling holes 10 so that they do not easily come off. However, it can be moved as described above.

따라서 체결밴드(1)의 양측부에 설치된 압지편장착대(4)에 모두 압지편(2)이 설치되면, 마주보는 압지편(2)을 볼트(8)와 너트(9)로 체결하여 조여주면 된다. 볼트(8)는 압지편(2)의 결합돌기(7)의 중심으로 관통된 볼트삽입공(6)에 끼워 반대측의 압지편(2)의 결합돌기(7)의 볼트삽입공(6)으로 인출하고, 이에 너트(9)를 체결하면 된다.Therefore, when the tack pieces 2 are installed on the tack piece mounting bases 4 provided on both sides of the fastening band 1, the opposing tack pieces 2 are fastened by tightening the bolts 8 and the nuts 9. You can give it. The bolt 8 is inserted into the bolt insertion hole 6 penetrated by the center of the engaging projection 7 of the tacking piece 2 to the bolt insertion hole 6 of the engaging projection 7 of the crushing piece 2 on the opposite side. What is necessary is just to take out and to fasten the nut 9 to this.

볼트(8)와 너트(9)의 체결로 체결밴드(1)는 더욱더 조여지게 되고, 체결밴드(1)의 내부에 삽입한 패드(5) 또한 더욱더 관(50)을 밀착하게 된다. 따라서 관(50)의 단부가 기밀되게 이음될 수 있다.The fastening band 1 is further tightened by the fastening of the bolt 8 and the nut 9, and the pad 5 inserted into the fastening band 1 also comes into close contact with the pipe 50. Thus, the end of the tube 50 can be hermetically joined.

본 발명은 또한 패드(5)에 형성된 수밀돌조(11)에 특징이 있다. 도 1과 도 5에 도시된 바와 같이 수밀돌조(11)는 두꺼운 돌조(12)와 얇은 돌조(13)로 구성되고, 얇은 돌조(13)는 하나 이상 형성되어 있다. 따라서 수압과 같은 큰 힘은 두꺼운 돌조(12)가 막고, 정밀한 수밀은 다수 개의 얇은 돌조(13)가 담당하게 된다. 따라서 하나의 돌조로 형성된 경우보다 다수 개의 돌조로 형성된 본 발명의 구조가 보다 확실하세 수밀을 이룰 수가 있게 된다.The present invention is also characterized by the watertight protrusion 11 formed on the pad 5. As shown in FIG. 1 and FIG. 5, the watertight protrusion 11 is composed of a thick protrusion 12 and a thin protrusion 13, and one or more thin protrusions 13 are formed. Therefore, a large force such as water pressure is blocked by the thick protrusion 12, and the precise water tightness is the responsibility of a plurality of thin protrusions (13). Therefore, the structure of the present invention, which is formed of a plurality of protrusions, is more certain than that of one protrusion, thereby achieving watertight.
