본 발명은, 확장돌기를 이용하여 관연결구의 양측에 삽입되는 주름관 내부를 이동하는 물이 주름관 밖으로 나와 관연결구 내주면과 주름관 외부에 형성된 골을 따라 외부로 이동하는 것을 방지할 수 있을 뿐 아니라, 특히 확장돌기의 끝단이 삽입되는 주름관과 맞닿도록 되어 있어 주름관이 관연결구 내부에 꽉 끼이면서 삽입되어 삽입된 후에는 잘 빠져나가지 않게 되며, 방수 성능을 보다 향상시킬 수 있도록 한, 확장돌기를 이용한 양방향 관연결구에 관한 것이다.The present invention, not only can prevent the water moving inside the corrugated pipe inserted into the both ends of the connector using the expansion protrusion to move out of the corrugated pipe and move to the outside along the bone formed on the inner peripheral surface of the pipe and the corrugated pipe. The end of the expansion protrusion is in contact with the corrugated pipe to be inserted, so that the corrugated pipe is tightly inserted inside the pipe connection and is not easily escaped after being inserted. The bidirectional pipe using the expansion protrusion can further improve waterproof performance. It is about a connector.

양방향 관연결구에 관한 기술로, 서로 연결될 관의 단부를 확관하여 서로 맞대고, 그 사이에 특별한 패킹부재와, 고정부재를 삽입한 후, 확관의 외부에서 클램프로 결합시킴으로써, 패킹부재에 의한 결합구조에 의해 관내의 압력변화에 능동적으로 작용하여 강력한 수밀력을 얻을 수 있도록 한 '관연결구조'(한국 공개특허공보 10-2007-0093784)가 공개된 바 있다.In the technology related to the two-way pipe connector, the ends of the pipes to be connected to each other by expanding, but a special packing member and the fixing member is inserted therebetween, and then coupled by a clamp from the outside of the expansion pipe, the coupling structure by the packing member By the 'pipe connection structure' (Korean Patent Publication No. 10-2007-0093784) has been disclosed to actively act on the pressure change in the pipe to obtain a strong watertight force.

아울러, 관의 단부에 용이하게 융착 또는 삽입하여 관과 관을 결합할 수 있도록 한 '관연결용 소켓 및 이를 구비한 관'(한국 등록특허공보 제10-0724794호)이 본 출원인에 의해 출원되어 등록받은 바 있다.In addition, a 'pipe connection socket and a pipe having the same' (Korea Patent Publication No. 10-0724794), which can be easily fused or inserted at the end of the pipe to couple the pipe and the pipe, has been filed by the present applicant. I have been registered.

상기와 같은 기술들은 관 연결 작업을 용이하게 하고, 방수 성능을 향상시킨 것들이다.Such techniques are those that facilitate pipe work and improve waterproof performance.

그런데, 위와 같은 관연결구를 이용하여 관을 연결시킬 때, 관연결구에 끼워지는 관이 주름관일 경우 관연결구 내측에 끼워진 주름관의 끝단부로부터 관연결구 내주면 사이로 물의 흐름이 발생될 때 주름관의 골을 타고 물이 관연결구 밖으로 이동하는 현상이 발생되는 문제점이 있었다.By the way, when connecting the pipe by using the above pipe connector, when the pipe is inserted into the pipe connector is a corrugated pipe when the flow of water from the end of the end of the corrugated pipe inserted inside the pipe connector between the inner peripheral surface of the pipe joint to take the corrugated pipe There was a problem that the water moves out of the connector.

특히, 이러한 현상은 관연결구의 양방향에 관이 연결되어 있거나, 양방향 관연결구 일측에 관이 연결되어 있는 경우 관연결구와 주름관 연결부위에 강한 압력이 발생하면서 일어나게 된다.In particular, this phenomenon occurs when the pipe is connected to both sides of the pipe connection, or when the pipe is connected to one side of the two-way pipe connector and a strong pressure occurs in the pipe connection and the corrugated pipe connection.

또한, 등록특허 제10-0724794호의 경우 방수 성능을 향상시키기 위하여 관연결구 내부에 관연결구 형태에 버금가는 패킹을 설치하고, 홀더를 설치하는 등 많은 구성요소를 필요로 하는 문제점이 있었다.In addition, in the case of Patent No. 10-0724794, there is a problem in that a lot of components are required, such as installing a packing similar to that of a pipe connector inside the pipe connector and installing a holder in order to improve waterproof performance.

본 발명의 확장돌기를 이용한 양방향 관연결구는 위와 같은 종래 기술에서 발생되는 문제점을 해소하기 위한 것으로, 확장돌기를 이용하여 관연결구의 양측에 삽입되는 주름관 내부를 이동하는 물이 주름관 밖으로 나와 관연결구 내주면과 주름관 외부에 형성된 골을 따라 외부로 이동하는 것을 방지하려는 것이다.Bidirectional connector using the expansion protrusion of the present invention is to solve the problems caused in the prior art as described above, the water moving inside the corrugated pipe inserted into both sides of the pipe using the expansion protrusion out of the corrugated pipe inner peripheral surface It is intended to prevent movement to the outside along the bone formed outside the corrugated pipe.

특히, 관연결구 자체의 형상만으로 이러한 방수성을 갖도록 함으로써 방수 성능을 향상시키기 위한 별도의 구성요소가 최소한으로 소요되도록 함으로써 시공을 간편하게 하고, 최소한의 부품이 소요되도록 함으로써 경제성을 향상시키려는 것이다.In particular, it is intended to improve the economics by simplifying the construction by having a minimum amount of separate components for improving the waterproof performance by having such a waterproofness only in the shape of the pipe connector itself, and the minimum components are required.

또한, 확장돌기의 끝단이 관연결구 내부로 삽입되는 주름관과 맞닿도록 구성함으로써 주름관이 관연결구 내부에 꽉 끼이면서 삽입되고, 삽입된 후에는 잘 빠져나가지 않게 함으로써 관연결구와 주름관의 상호 고정을 위해 필요한 구성요소를 최소화하려는 것이다.In addition, the end of the expansion protrusion is configured to abut the corrugated pipe inserted into the connector, so that the corrugated pipe is inserted while being tightly inserted into the tube, and it does not escape well after being inserted so that it is necessary for mutual fixing of the connector and the corrugated pipe. We want to minimize the components.

아울러, 위와 같은 확장돌기를 이용하여 관연결구와 주름관의 고정을 강화시킴으로써 방수 성능을 보다 향상시킬 수 있게 하려는 것이다.In addition, by using the expansion protrusions as described above to enhance the fixing of the pipe and the corrugated pipe to improve the waterproof performance.

이때, 방수 성능을 향상시키고 관연결구와 주름관 상호 고정을 견고히 하기 위하여, 확장돌기연결부는 관삽입공간의 두께보다 더 길게 형성되어 있고, 확장돌기는 양측이 확장돌기연결부로부터 휘어진 채 형성되어 있고, 양측 끝단이 확장돌기연결부와 이격된 채 주름관과 맞닿도록 구성되어 있는 것을 특징으로 한다.At this time, in order to improve the waterproof performance and to secure the pipe joint and the corrugated pipe mutual fixing, the expansion projection connecting portion is formed longer than the thickness of the pipe insertion space, the expansion projection is formed on both sides bent from the expansion projection connection, both sides The end is characterized in that it is configured to contact the corrugated pipe while being spaced apart from the expansion protrusion connection.

본 발명에 의해, 확장돌기를 이용하여 관연결구의 양측에 삽입되는 주름관 내부를 이동하는 물이 주름관 밖으로 나와 관연결구 내주면과 주름관 외부에 형성된 골을 따라 외부로 이동하는 것을 방지할 수 있게 된다.According to the present invention, it is possible to prevent the water moving inside the corrugated pipe inserted into both sides of the connector using the expansion protrusion to move out of the corrugated pipe and move outward along the bone formed on the inner peripheral surface of the pipe and the corrugated pipe.

특히, 관연결구 자체의 형상만으로 이러한 방수성을 갖도록 함으로써 방수 성능을 향상시키기 위한 별도의 구성요소가 최소한으로 소요되도록 함으로써 시공을 간편하게 하고, 최소한의 부품이 소요되도록 함으로써 경제성이 향상된다.In particular, by having only such a shape of the connector itself has such a waterproof property to minimize the separate components to improve the waterproof performance by simplifying the construction, the minimum components are required to improve the economics.

또한, 확장돌기의 끝단이 관연결구 내부로 삽입되는 주름관과 맞닿도록 구성 함으로써 주름관이 관연결구 내부에 꽉 끼이면서 삽입되고, 삽입된 후에는 잘 빠져나가지 않게 함으로써 관연결구와 주름관의 상호 고정을 위해 필요한 구성요소가 최소화된다.In addition, the end of the expansion protrusion is configured to abut the corrugated pipe inserted into the connector, so that the corrugated pipe is inserted while being tightly inserted into the tube, and does not come out well after being inserted so that it is necessary for the mutual fixing of the tube and the corrugated pipe. The component is minimized.

아울러, 위와 같은 확장돌기를 이용하여 관연결구와 주름관의 고정을 강화시킴으로써 방수 성능을 보다 향상시킬 수 있게 된다.In addition, it is possible to further improve the waterproof performance by reinforcing the fixing of the pipe and the corrugated pipe by using the above-described expansion protrusion.

이하, 본 발명의 확장돌기를 이용한 양방향 관연결구의 각 구성요소에 대해 첨부된 도 1 내지 도 5를 통해 상세히 설명하면 다음과 같다.Hereinafter, the components of the bidirectional connector using the expansion protrusion of the present invention will be described in detail with reference to FIGS. 1 to 5.

제1수평부(10)는 도 1 및 도 3에 도시된 바와 같이 내벽면에 주름관(20)이 끼워지도록 일정한 내경을 갖는 원통 형상으로 형성되어 있다.As illustrated in FIGS. 1 and 3, the first horizontal portion 10 is formed in a cylindrical shape having a constant inner diameter so that the corrugated pipe 20 is fitted to the inner wall surface.

아울러, 제1수평부(10)는 합성수지 재질로 형성되어 있는 것이 가장 바람직하다.In addition, the first horizontal portion 10 is most preferably formed of a synthetic resin material.

확장돌기연결부(13)는 도 1 및 도 3에 도시된 바와 같이 제1수평부(10) 내측 중앙측에 형성되어 있는데, 꼭 중앙에만 위치해야 하는 것은 아니며, 필요한 사양에 따라 다양한 위치에 형성할 수도 있다.The expansion protrusion connecting portion 13 is formed on the inner side of the first horizontal portion 10, as shown in Figures 1 and 3, but is not necessarily located only in the center, it may be formed in various positions according to the required specifications It may be.

아울러, 확장돌기연결부(13)는 제1수평부(10)의 내주면을 따라 형성되어 있으며, 제1수평부(10)를 수직으로 절단하였을 때 완전한 원형을 이룰 수 있도록 형성되어 있는 것이 좋다.In addition, the expansion protrusion connecting portion 13 is formed along the inner circumferential surface of the first horizontal portion 10, and may be formed to form a complete circle when the first horizontal portion 10 is vertically cut.

또한, 확장돌기연결부(13)는 제1수평부(10)와 연결되는 부분과 끝단 부분의 두께 및 폭이 일정한 두께 및 폭을 갖는 것이 바람직하다 할 것이다.In addition, it is preferable that the extension protrusion connecting portion 13 has a constant thickness and width of the portion and the end portion connected to the first horizontal portion 10.

또한, 확장돌기연결부(13)는 제1수평부(10)와 일체로 합성수지 재질로 형성되어 있는 것이 가장 바람직하다 할 것이다.In addition, it is most preferable that the expansion protrusion connecting portion 13 is formed of a synthetic resin material integrally with the first horizontal portion 10.

한편, 확장돌기(14)는 도 1 및 도 3에 도시된 것처럼 확장돌기연결부(13)와 일체로 연속하여 형성되어 있는데, 도시된 것처럼 확장돌기연결부(13)보다 폭이 크게 형성되어 있다.Meanwhile, as shown in FIGS. 1 and 3, the extension protrusions 14 are integrally formed with the extension protrusion connection part 13, and are wider than the extension protrusion connection part 13 as shown.

아울러, 확장돌기연결부(13)보다 큰 폭을 가지면서 형성되어 있어 확장돌기연결부(13)를 기준으로 제1수평부(10) 양측의 내벽면에 각각 관삽입공간(15)이 형성되어 있음을 알 수 있다.In addition, it is formed having a larger width than the expansion protrusion connecting portion 13, the pipe insertion space 15 is formed on each of the inner wall surface on both sides of the first horizontal portion 10, based on the expansion protrusion connecting portion (13) Able to know.

이 관삽입공간(15)에는 주름관(20)이 끼워지게 된다.The corrugated pipe 20 is fitted into the pipe insertion space 15.

이러한 확장돌기(14)는 도 1 및 도 3, 4와 같이 확장돌기연결부(13)로부터 버섯 형태로 끝단이 호형을 이루면서 하부는 주름관(20)을 덮어 물의 흐름을 방지하도록 형성되어 있다.The expansion protrusions 14 are formed to prevent the flow of water by covering the corrugated pipe 20 while the ends are arc-shaped from the expansion protrusion connecting portion 13 in the form of mushrooms as shown in Figs.

한편, 도 5에서는 보다 개량된 형태의 확장돌기(14)의 형태를 도시하였다.On the other hand, Figure 5 shows the shape of the expansion protrusion 14 of a more improved form.

도 5의 확장돌기(14)를 살펴보면, 먼저 확장돌기연결부(13)의 길이가 앞선 예보다 더 길게 형성되어 있어 관삽입공간(15)의 두께보다 더 길게 형성되어 있음을 알 수 있다.Looking at the expansion protrusion 14 of Figure 5, it can be seen that the length of the expansion protrusion connecting portion 13 is formed longer than the previous example is formed longer than the thickness of the tube insertion space (15).

아울러, 확장돌기연결부(13)로부터 일체가 된 채 형성된 확장돌기(14)는 그 끝단이 주름관(20)에 맞닿도록 구성되어 있다.In addition, the expansion protrusion 14 formed integrally from the expansion protrusion connecting portion 13 is configured such that the end thereof abuts the corrugated pipe 20.

즉, 도 5에 도시된 것처럼 확장돌기연결부(13)와 확장돌기(14) 사이에 공간(16)이 형성되어 있고, 확장돌기(14) 하부의 접촉부(17) 위치는 앞선 예에 비해 관삽입공간(15)측에 더 가까이 위치하여 사실상 주름관(20)이 삽입될 때 확장돌기(14)의 접촉부(17)가 주름관(20) 외부와 꽉 끼이도록 구성되어 있다.That is, as shown in FIG. 5, a space 16 is formed between the extension protrusion connecting portion 13 and the extension protrusion 14, and the position of the contact portion 17 below the extension protrusion 14 is inserted into the tube as compared with the previous example. Positioned closer to the space 15 side, virtually the contact portion 17 of the expansion protrusion 14 is configured to fit tightly with the outside of the corrugated pipe 20 when the corrugated pipe 20 is inserted.

이와 같이 구성하게 되면 주름관(20)이 완전히 삽입된 후 주름관(20)이 잘 빠져나가지 못하게 될 뿐만 아니라 그 힘에 의하여 방수성이 보다 향상되게 된다.In this configuration, after the corrugated pipe 20 is completely inserted, the corrugated pipe 20 is not easily removed, and the waterproofness is further improved by the force.

한편, 경사부(11)는 제1수평부(10)의 양측 끝단의 외주면으로부터 일정한 각도로 확장되면서 제1수평부(10)와 일체로 형성되어 있다.On the other hand, the inclined portion 11 is formed integrally with the first horizontal portion 10 while extending at a predetermined angle from the outer peripheral surface of both ends of the first horizontal portion 10.

경사부(11)가 형성된 이유는 도 4에 도시된 것처럼 관연결구와, 관연결구에 삽입된 주름관(20) 사이에 고무링(30)을 설치하여 방수 성능을 갖도록 하기 위함이다.The reason why the inclination part 11 is formed is to install a rubber ring 30 between the pipe and the corrugated pipe 20 inserted in the pipe as shown in FIG. 4 to have waterproof performance.

한편, 제2수평부(12)는 경사부(11)의 양측 끝단으로부터 일정한 내경을 가지면서 경사부(11)와 일체로 형성되어 있다.On the other hand, the second horizontal portion 12 is integrally formed with the inclined portion 11 while having a constant inner diameter from both ends of the inclined portion 11.

제2수평부(12)는 도 4에 도시된 것처럼 고무링(30)이 삽입된 상태에서 등록특허 제10-0762990호에 도시된 것과 같은 결합판(40)의 돌출턱이 관연결구와 주름관(20) 사이 공간에 끼여지도록 하기 위함이다.As shown in FIG. 4, the second horizontal portion 12 has a protruding jaw of the coupling plate 40 as shown in Korean Patent No. 10-0762990 in the state where the rubber ring 30 is inserted into the pipe connector and the corrugated pipe ( 20) It is to be inserted in the space between.

한편, 도 4에 도시된 것처럼 본 발명의 관연결구와 주름관(20) 사이에 고무링(30)과 결합판(40)이 끼여진 상태에서는 홀더(50)가 체결되어 주름관(20)이 본 발명의 관연결구에 고정된 상태를 유지할 수 있도록 되어 있다.On the other hand, the rubber ring 30 and the coupling plate 40 is sandwiched between the tube connector and the corrugated pipe 20 of the present invention as shown in Figure 4, the holder 50 is fastened so that the corrugated pipe 20 is the present invention It is designed to maintain a fixed state in the pipe connection of the.

이상과 같이 구성된 본 발명의 확장돌기를 이용한 양방향 관연결구는 양 방향에서 간편하게 주름관(20)을 연결할 수 있으며, 양방향에서 주름관(20)을 연결한 상태에서 주름관(20)에 형성되어 있는 골을 통해 관연결구 내측으로부터 주름관(20) 외측으로 물이 새는 것을 손쉽게 방지할 수 있어 종래의 관연결구에 비해 월등한 방수 성능을 제공할 수 있게 되며,The bidirectional tube connector using the expansion protrusion of the present invention configured as described above can be easily connected to the corrugated pipe 20 in both directions, and through the bone formed in the corrugated pipe 20 in the state connected to the corrugated pipe 20 in both directions. It is possible to easily prevent the leakage of water from the inner side of the corrugated pipe to the outside of the corrugated pipe 20, it is possible to provide a superior waterproof performance compared to the conventional pipe connector,

특히, 일차적인 방수 성능을 관연결구의 형상만으로 보장해주게 되므로 방수 성능을 향상시키기 위한 각종 구성요소 및 시공 과정이 덜 필요하게 되는 장점을 갖게 된다 할 것이다.In particular, since the primary waterproof performance is guaranteed only by the shape of the connector, various components and construction processes for improving the waterproof performance will be required.

이상과 같이 구성된 본 발명의 확장돌기를 이용한 양방향 관연결구는 주름관 과 연결할 때 가장 큰 효과를 발휘하나 꼭 이에 한정되는 것은 아니며, 각종 관을 연결할 때 사용할 수도 있다 할 것이다.The bidirectional pipe joint using the expansion protrusion of the present invention configured as described above has the greatest effect when connected with the corrugated pipe, but is not necessarily limited thereto, and may be used when connecting various pipes.
