용수관연결부재의 용수관 조임구{Water pipeline tightener of water pipeline connecting members}Water pipeline tightener of water pipeline connecting members

본 고안은 합성수지재 용수관을 이음하는 용수관연결부재의 용수관 조임구에 관한 것으로서, 보다 구체적으로는 연결부재본체와 결합되는 캡의 내측에 장치되어 캡과 본체의 조임에 의해 용수관의 단부를 조임하여 고정하는 조임구가 캡의 경사면을 따라 내경이 축소됨과 동시에 용수관을 캡을 따라 회전하도록 하여 결합되는 용수관의 둘레를 조임구의 조임돌기가 파고들어 보다 견고하게 결합할 수 있도록 하는 용수관연결부재의 용수관 조임구에 관한 것이다.The present invention relates to a water pipe tightening port of the water pipe connecting member for joining the synthetic resin water pipe, and more specifically, is installed inside the cap coupled to the connecting member body, the end of the water pipe by tightening the cap and the main body The fasteners for tightening and tightening are reduced in diameter along the inclined surface of the cap, and at the same time, the water pipes are rotated along the caps so that the fasteners of the fasteners can penetrate the circumference of the combined water pipes so that they can be joined more firmly. It relates to a water pipe fastener of the pipe connecting member.

일반적으로 공업용수 및 농업용수 등을 원하는 목적지까지 운반할 수 있도록 하는 용수관은 이음매가 없이 사용함이 누수 등을 방지할 수 있어 가장 바람직 하지만, 운반 및 취급의 편리성을 위하여 제조공장에서 일정길이로 절단하여 공급되고 사용중에 부분적 손상으로 인하여 손상된 부분을 절단하여 제거하고 절단된 용수관을 연결하는 등 용수관의 길이를 확장하기 위하여 용수관 연결부재를 이용하여 연결하여 사용하게 된다.Generally, a water pipe that can transport industrial water and agricultural water to a desired destination is most preferable because it can be used without a seam to prevent leakage. It is supplied by cutting and using the water pipe connection member to extend the length of the water pipe such as cutting and removing the damaged part due to partial damage during use and connecting the cut water pipe.

또한 용수를 단속하기 위하여 사용되는 밸브 및 용수관을 분기하여 다방향으로 용수를 공급하도록 하는 분기관 등 용수관을 단속하는 연결자재로서 다양한 종류의 용수관 이음용 연결부재가 사용되고 있다.In addition, various types of connection members for water pipe joints are used as a connecting material for intercepting water pipes such as branch pipes for branching valves and water pipes to supply water in multiple directions.

상기에서 주지한 용수관 연결부재에 용수관을 결합하기 위하여서 연결부재 본체에 나사결합되는 캡과 캡의 내측에 조임구가 위치하여 용수관의 단부를 조임하여 고정한다.In order to couple the water pipe to the water pipe connecting member well-known above, the cap is screwed to the connecting member main body and a fastener is located inside the cap to tighten and fix the end of the water pipe.

일반적으로 연결부재본체에 장치되는 조임구는 도 6에서와 같이 일측 외경이 경사지게 형성되고 그 둘레에 축방향으로 다수의 신축홈을 형성하며 내측에 원주방향으로 조임돌기을 형성하고 본체의 나사결합되는 캡의 내경은 외협내광의 경사를 가지며 형성함으로서 조임구는 캡이 본체와 나사결합함에 따라 조임구의 일측이 패킹고정링과 밀착되어 이동이 제한되고 동시에 캡은 본체방향으로 이동함으로 캡의 내경이 좁아지게 된다.In general, the fasteners provided in the connecting member main body is formed with one outer diameter inclined as shown in FIG. As the inner diameter is formed with the inclination of the outer narrow light, the fastener is limited by the one side of the fastener is in close contact with the packing fixing ring as the cap is screwed with the main body and at the same time the cap is moved toward the main body to narrow the inner diameter of the cap.

따라서 캡의 내경에 장치되는 조임구 일측이 신축홈에 의해 캡의 내경을 따라 휘어져 그 내경이 축소됨으로 조임구의 내경에 투입된 용수관을 가압돌환이 가압고정하는 구조로 되어 있다.Therefore, one side of the cap is installed on the inner diameter of the cap is bent along the inner diameter of the cap by the expansion groove is reduced in its inner diameter is a structure in which the pressure return to pressurize the water pipe injected into the inner diameter of the cap.

종래의 용수관연결부재의 용수관고정부는 캡을 본체에 나사조임 함으로서 캡의 내경에 형성되는 경사면을 따라 조임구의 내경이 축소되어 용수관의 외경을 가압밀착하여 고정함과 동시에 조임구가 패킹고정링을 본체방향으로 가압함으로서 패킹고정링이 패킹을 가압하여 패킹 또한 용수관의 외면에 밀착하여 기밀을 유지하는 구조로 되어 있다.The water pipe fixing part of the conventional water pipe connecting member is screwed on the main body to reduce the inner diameter of the tightening hole along the inclined surface formed on the inner diameter of the cap, thereby press-fitting and fixing the outer diameter of the water pipe. By pressing the ring in the direction of the main body, the packing retaining ring pressurizes the packing so that the packing is also in close contact with the outer surface of the water pipe to maintain airtightness.

하지만 상기와 같이 되는 종래의 조임구는 도 6에서와 같이 단순히 용수관의 외부를 둘레를 가압하여 고정하는 구조로 이는 고정력이 견고하지 못하여 기온의 변화에 따른 용수관 및 이음구의 팽창과 축소 등에 의한 가압력의 변화에 의해 그 조임력이 변화하게 됨으로 사용중 용수관 내의 용수압력에 의해 용수관이 조임구로부터 후측으로 밀려 누수 등이 쉽게 발생하게 되고 심하면 용수관이 조임구로부터 분리되는 등의 문제점이 있었다.However, the conventional fasteners as described above is a structure for simply fixing the outside of the water pipe by pressing the circumference as shown in FIG. 6, which is not a firm force, and the pressing force due to expansion and contraction of the water pipe and the fitting port according to the change in temperature. As the tightening force is changed by the change of, the water pipe is pushed from the tightening port to the rear side due to the water pressure in the water pipe during use, so that leakage occurs easily, and if the water pipe is severely separated from the tightening port.

본 고안은 상기와 같은 문제점을 개선코자 안출한 것으로서, 조임구의 내면에 형성된 조임돌기가 용수관의 외주둘레를 파고들 수 있도록 하여 보다 견고한 결합을 이룰 수 있도록 한 것이며 이를 위하여 본 고안은 조임구의 외주가 캡의 내경에 밀착되어 캡의 회전력이 조임구에 전달되도록 함으로서 조임구의 조임돌기가 용수관의 둘레를 깎아서 파고들 수 있도록 하여 용수관을 보다 견고히 결합할 수 있도록 하는 용수관연결부재의 용수관 조임구를 제안함에 그 목적이 있다.The present invention has been devised to improve the above problems, the fastening protrusion formed on the inner surface of the fastener can be dug into the outer circumference of the water pipe to achieve a more robust coupling and for this purpose, the present invention is the outer circumference of the fastener Water pipe of the water pipe connection member so that the water tightness of the cap can be more firmly coupled by allowing the capping protrusion of the fastener to squeeze the periphery of the water pipe so that the rotation force of the cap is transmitted to the fastener. The purpose is to propose a fastener.

상기와 같은 목적을 달성하기 위하여 본 고안은 내경에 용수관과 결합하는 조임돌기를 가진 조임구의 외주둘레에 축방향으로 치형을 다수 형성함으로서 캡의 내경에 밀착하는 치형의 마찰력이 조임돌기가 용수관에 밀착하는 마찰력보다 크게 하여 조임구가 캡의 내면을 따라 회전할 수 있도록 하여 상기의 목적을 달성할 수 있게 된다.In order to achieve the above object, the present invention forms a plurality of teeth in the axial direction on the outer circumference of the fastener having a fastening protrusion coupled to the water pipe in the inner diameter, so that the frictional force of the teeth close to the inner diameter of the cap is tightened in the water pipe. It is possible to achieve the above object by allowing the fastener to rotate along the inner surface of the cap by greater than the frictional force in close contact with the cap.

상기와 같이되는 본 고안은 조임구의 치형이 캡의 내면과 밀착시에 축방향으로 길게 밀착되어 캡과 함께 회전함으로서 조임돌기가 용수관의 외주둘레를 깎으며 용수관의 외주를 파고들어 가압밀착되어 용수관이 견고하게 조임구에 고정된다. The present invention as described above, the teeth of the fastener is in close contact with the inner surface of the cap long in the axial direction is rotated together with the cap, so that the tightening projection cuts the outer circumference of the water pipe and press-contacted by digging the outer circumference of the water pipe The water pipe is firmly fixed to the fastener.

따라서 기온의 변화에 따른 용수관 및 이음구의 팽창과 축소 등의 범위를 넘어서 용수관과 조임구가 결합됨으로 누수를 방지하고 용수관이 조임구로부터 분리되는 것을 방지할 수 있는 이점이 있다.Therefore, there is an advantage that can prevent the leakage and separation of the water pipe from the fastener by combining the water pipe and the fastener over the range of expansion and contraction of the water pipe and the joint according to the change in temperature.

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

먼저, 도 2는 본 고안의 조립실시예를 나타낸 단면예시도이며, 도 3에 본 고안조임구의 요부인 치형 나타낸 사시도와 확대도가 도시되어 있다.First, Figure 2 is an exemplary cross-sectional view showing an embodiment of the present invention, Figure 3 is a perspective view and an enlarged view showing the teeth of the main design of the present invention.

즉 본 고안은 외주둘레를 캡(2)의 내면에 대응하게 경사상으로 형성하고 그 둘레에 다수의 신축홈(301)을 형성하며 내경의 둘레에 다수의 조임돌기(302)를 형성하여서 되는 조임구(3)에 있어서;That is, the present invention is formed by forming the outer periphery in an inclined shape corresponding to the inner surface of the cap (2), forming a plurality of expansion grooves (301) around the periphery, and forming a plurality of tightening protrusions (302) around the inner diameter In sphere (3);

조임구(3)의 외주둘레에 일방향으로 그 끝이 날카롭게 형성되는 다수의 치형(303)을 축방향으로 길게 형성한 구조이다.A plurality of teeth 303, the ends of which are sharply formed in one direction on the outer circumference of the fastener 3, are formed in the axial direction to be long.

상기와 같이 되는 본 고안은 캡(2)의 내면에 축방향으로 치형(303)이 밀착되어 회전하는 캡(2)의 회전력을 조임구(3)에 전달함으로서 조임구(3)가 회전하게 된다.In the present invention as described above, the fastener 3 is rotated by transmitting the rotational force of the cap 2 to the fastener 3 by rotating the tooth 303 in close contact with the inner surface of the cap 2 in the axial direction. .

상기에 있어서 캡(2)의 내면에 밀착되는 치형(303)은 축방향, 즉 캡(2)이 본체(1)와 나선결합하여 이동하는 방향으로는 밀착이 최소화됨으로 되어 조임구(3)의 위치가 쉽게 이동하게 되어 캡(2)의 내경을 따라 조임구(3)의 내경이 원활하게 축 소되는 것이며 캡(2)의 회전방향으로는 치형이 길게 밀착되어 저항이 보다 크게 형성됨으로서 조임구(3)는 캡(2)을 따라 회전하게 된다.In the above, the teeth 303 which are in close contact with the inner surface of the cap 2 are axially, that is, the close contact is minimized in the direction in which the cap 2 is helically coupled to the main body 1, so that The position is easily moved so that the inner diameter of the fastener 3 is smoothly reduced along the inner diameter of the cap 2, and the teeth are closely contacted in the rotational direction of the cap 2 so that the resistance is made larger. 3 rotates along the cap 2.

따라서 조임구(3)의 내면에 형성된 조임돌기(302)가 용수관(4)의 둘레를 파고들어 가압고정하게 되는 것이다. Therefore, the tightening protrusion 302 formed on the inner surface of the tightening hole 3 is to pierce the circumference of the water pipe (4) to be fixed by pressure.

한편 상기의 치형(303)은 일방향으로 방향성을 가지도록 형성할 수도 있다.On the other hand, the teeth 303 may be formed to have a direction in one direction.

즉 치형(303)을 캡(2)의 잠금시 회전방향으로 저항을 증대하는 톱니형으로 형성하여 용수관(4)을 결합하여 캡(2)의 조임시에는 조임구(3)가 캡(2)을 따라서 회전하고 캡(2)의 풀림시에는 캡(2)과 조임구(3)의 저항을 줄여 캡(2)이 공회전하게 할 수도 있다. That is, the teeth 303 are formed in a sawtooth shape that increases resistance in the rotational direction when the cap 2 is locked, and the water pipe 4 is coupled to each other so that the fastener 3 is closed when the cap 2 is tightened. When rotating along the) and the cap 2 is released, the resistance of the cap 2 and the fastener 3 may be reduced to allow the cap 2 to idle.
