종래의 관 연결구로서는 실용신안등록 제420349호에 개시되어 있는 것이 있으며 도 7에 도시되어 있다. 도 7에 도시되어 있는 관 연결용 밴드는 본체(10)에 클램프(20) 한 쌍이 서로 마주보며 'ㄴ'자 형상의 단면을 갖도록 형성되어 있는데, 이런 종래의 관 연결용 밴드는 관이 매설되어 있는 땅의 기온이 상승되어 외경이 확장될 경우 볼트체결부에만 압력이 가해지므로 클램프 사이의 틈이 벌어지게 되고 이로 인해 그 틈새로 물이 샐 우려가 많다.Conventional pipe connectors are disclosed in Utility Model Registration No. 420349 and are shown in FIG. The pipe connecting band shown in Figure 7 is formed to have a cross-section of the 'b' shape and a pair of clamps 20 facing each other on the main body 10, this conventional pipe connection band is a tube buried When the temperature of the ground is increased and the outer diameter is expanded, pressure is applied only to the bolted joints, which leads to a gap between the clamps, which causes water leakage.

더군다나, 팽창, 수축의 과정을 수회 반복하게 되면 클램프의 형상이 찌그러져 소망하는 관 연결구의 기밀효과를 얻기가 어렵다.In addition, repeated expansion and contraction of the process several times, the shape of the clamp is distorted, it is difficult to obtain the airtight effect of the desired tube connector.

또 다른 것으로서는 본 출원인이 선출원한 특허 제562754호와 같은 것으로서 도 8에 도시되어 있다. 도 8에 도시되어 있는 합성수지관체 연결구는 높은 기밀성을 가지고 있으나 체결구 내에 다수의 압지편(7)을 형성함으로써 그 제작비용이 상승되는 문제가 있다.Another example is shown in FIG. 8 as the same as the patent No. 562754 filed by the applicant. The synthetic resin pipe connector shown in FIG. 8 has a high airtightness, but there is a problem in that the manufacturing cost is increased by forming a plurality of tack pieces 7 in the fastener.

따라서, 본 발명은 체결밴드, 압지판 및 체결돌기가 형성된 합성수지관 연결구를 제공하되, 상기 체결돌기는 결합중심축에서 서로 마주보도록 바깥쪽으로 컬링하여 체결돌기의 강도를 향상시키고, 상기 체결돌기의 단면이 원형이므로 합성수지관의 온도변화에 따른 외경변화에도 유연하게 대처할 수 있는 합성수지관 연결구를 제공하는데 그 목적이 있다.Accordingly, the present invention provides a synthetic resin pipe connector formed with a fastening band, a pressure plate and a fastening protrusion, wherein the fastening protrusion is curled outward to face each other at a coupling center axis to improve the strength of the fastening protrusion, and the cross section of the fastening protrusion. Since the circular shape, the purpose is to provide a synthetic resin pipe connector that can flexibly cope with changes in the outer diameter according to the temperature change of the synthetic resin pipe.

또한, 상기 합성수지관의 연결구는 제작비용을 낮추면서도 기밀효과를 상승시킬 수 있는 합성수지관 연결구를 제공하는데 또 다른 목적이 있다.In addition, the connector of the synthetic resin pipe is another object to provide a synthetic resin pipe connector that can increase the airtight effect while lowering the manufacturing cost.

본 발명은 체결밴드, 압지판 및 체결돌기가 형성된 합성수지관 연결구를 제공하되, 상기 체결돌기는 결합중심축에서 서로 마주보도록 바깥쪽으로 컬링하여 그 다면이 원형에 가깝도록 형성한다.The present invention provides a synthetic resin pipe connector formed with a fastening band, a pressure plate and a fastening protrusion, wherein the fastening protrusion is curled outwards to face each other at a coupling center axis so as to have a surface close to a circular shape.

또한, 상기 합성수지관의 연결구는 제작비용을 낮추면서도 기밀효과를 상승시킬 수 있다.In addition, the connector of the synthetic resin pipe can increase the airtight effect while lowering the manufacturing cost.

본 발명은 합성수지관 연결구에 관한 것으로서, 더욱 상세하게는 체결밴드, 압지판 및 체결돌기가 형성된 합성수지관 연결구에 있어서 상기 체결돌기를 결합중심축에서 바깥쪽으로 컬링하여 합성수지관의 조임력이 균일하게 작용됨과 동시에 탄성이 있도록 형성하여 온도 변화로 인해 합성수지관의 외경이 변하더라도 유연하게 대처할 수 있는 합성수지관 연결구이다.The present invention relates to a synthetic resin pipe connector, and more particularly, in the synthetic resin pipe connector formed with a fastening band, a pressure plate and a fastening protrusion, the fastening force of the synthetic resin pipe is uniformly acted by curling the fastening protrusion outward from the coupling center axis. At the same time, it is formed to be elastic, it is a synthetic resin pipe connector that can flexibly cope with the change in the outer diameter of the synthetic pipe due to temperature changes.

이하 첨부된 도면에 의해 본 발명의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일실시 예시도이고, 도 2는 도 1의 A-A 단면도로서, 본 발명에 의한 합성수지관 연결구는 체결밴드(10)와, 상기 체결밴드(10)의 내측에 파이프를 가압하는 압지판(11)과, 상기 체결밴드(10)의 외측에 결합되어 볼트삽입공(13)이 하나 이상 형성되어 있는 체결돌기(12)를 포함하여 구성된 합성수지관 연결구에 있어서, 상기 체결돌기(12)는 결합중심축(C)에서 바깥쪽으로 컬링되어 있으 며, 그 단면이 원형인 것이 특징이다.Figure 1 is an exemplary view of the present invention, Figure 2 is a cross-sectional view AA of Figure 1, the synthetic resin pipe connector according to the present invention is to fasten the pipe to the inside of the fastening band 10, the fastening band 10 In the composite resin pipe connector comprising a pressure plate (11) and a fastening protrusion (12) which is coupled to the outside of the fastening band (10) and at least one bolt insertion hole (13) is formed, the fastening protrusion (12) ) Is curled outward from the coupling center axis (C), and its cross section is circular.

먼저, 본 발명의 주요한 특징은 판상의 재료 끝부분을 그 단면이 원형에 가깝도록 컬링한 것에 있는데, 이로써 체결돌기의 강도가 판상의 체결돌기에 비해 상대적으로 매우 견고해질 뿐만 아니라, 양측 체결돌기(12)의 볼트(14) 결합 후 일정 한도 내에서 탄성을 가지게 된다.First, the main feature of the present invention is that the end of the plate-like material is curled so that its cross section is close to the circular, thereby not only makes the strength of the fastening protrusion relatively very firm compared to the plate-like fastening projections, 12) will have elasticity within a certain limit after the bolt 14 is coupled.

즉, 합성수지관을 내부에 삽입한 뒤 볼트(14)로서 견고히 결합하고 이후 지하에 매설하게 되면 땅의 온도가 상승할 때 합성수지관의 외경 역시 커지게 되면서 체결밴드(10)를 압박하게 되는데 종래의 판 형상의 체결돌기(12)는 관의 외경이 커짐으로 인해 체결돌기(클램프) 사이의 틈이 벌어지게 되고 이런 과정이 수차례 반복되게 되면 결국 그 틈으로 유체가 새게 된다.That is, if the synthetic resin tube is inserted into the inside and then firmly coupled as a bolt (14) and then buried underground, the outer diameter of the synthetic resin tube is also increased when the temperature of the ground rises, and the fastening band 10 is pressed. The plate-shaped fastening protrusions 12 have a gap between the fastening protrusions (clamps) due to an increase in the outer diameter of the pipe, and when this process is repeated several times, the fluid leaks into the gaps.

그러나, 본 발명에 의한 연결구의 클램프는 그 단면이 원형이므로 합성수지관의 외경이 커질 때 r 즉, 체결돌기의 볼트삽입공 방향의 외경이 줄어들면서 체결밴드(10)의 외경이 상대적으로 커지게 되어 기밀상태가 유지된다.However, since the clamp of the connector according to the present invention has a circular cross section, when the outer diameter of the synthetic resin tube increases, that is, the outer diameter of the fastening band 10 becomes relatively large as the outer diameter in the direction of the bolt insertion hole of the fastening protrusion decreases. Confidentiality is maintained.

이 상태에서는 r' 즉, r과 수직되는 방향의 외경은 상대적으로 커지게 된다.In this state, r ', that is, the outer diameter in the direction perpendicular to r becomes relatively large.

이후 온도의 하강으로 합성수지관의 외경이 줄어들게 되면 체결돌기(12)는 탄성이 있는 금속체이므로 원래의 형상을 유지하려는 탄성력으로 인해 r의 외경이 다시 커지게 되고 상대적으로 체결밴드(10)의 외경이 작아지게 되어 기밀상태가 유 지된다.Then, when the outer diameter of the synthetic resin tube is reduced due to the temperature drop, the fastening protrusion 12 is an elastic metal body, so the outer diameter of r is increased again due to the elastic force to maintain the original shape, and the outer diameter of the fastening band 10 is relatively large. Becomes smaller and maintains hermeticity.

도 3은 본 발명의 타실시 예시도이고, 도 4는 도 3의 A-A 단면도로서, 체결돌기(12)에 볼트삽입공(13) 대신 상기 볼트삽입공보다 큰 체결홈(16)을 형성하고, 상기 체결홈(16)에는 합성수지재의 체결블록(15)이 결합되는 것이다.3 is another exemplary view of the present invention, Figure 4 is a cross-sectional view AA of Figure 3, forming a fastening groove 16 larger than the bolt insertion hole instead of the bolt insertion hole 13 in the fastening projection 12, The fastening groove 16 is to be coupled to the fastening block 15 of the synthetic resin material.

그리고, 상기 체결블록(15)에는 볼트삽입공(13)을 형성하여 볼트(14) 결합시 나사산의 파손을 방지한다.In addition, the fastening block 15 forms a bolt insertion hole 13 to prevent breakage of the screw thread when the bolt 14 is coupled.

도 5는 본 발명에 의한 체결블록(15)의 타실시 예시도로서, 볼트삽입공(13)을 원이 아닌 장공(17)으로 형성하여 볼트(14)의 체결을 더욱 용이하게 할 수 있다.5 is a diagram illustrating another embodiment of the fastening block 15 according to the present invention, and the bolt insertion hole 13 may be formed as a long hole 17 instead of a circle to further facilitate the fastening of the bolt 14.

도 6은 본 발명의 또 다른 실시예시도로서, 체결돌기(12)를 볼트(14)가 체결되는 부분마다 분리하여 구성한 것이다. 6 is a view showing another embodiment of the present invention, in which the fastening protrusions 12 are separately formed for each of the parts to which the bolts 14 are fastened.

이런 실시예는 상하에 형성된 체결돌기마다 볼트의 결합량을 다르게 할 수 있으므로 각가의 체결돌기마다 체결력이 다르게 작용될 수 있다. In this embodiment, the coupling amount of the bolts may be different for each fastening protrusion formed above and below, so that the fastening force may be different for each fastening protrusion.
