본 고안은 예로, 청소기의 밀대 등에 사용되는 파이프 연결구조에 관한 것으로, 특히 다수개의 파이프를 조립하였을 시 고정력이 확보되어 흔들거림 없이 연결상태를 안정적으로 유지할 수 있도록 한 파이프 연결구조에 관한 것이다.The present invention, for example, relates to a pipe connecting structure used for the pusher of the cleaner, and more particularly relates to a pipe connecting structure to ensure a stable connection state without a shake is secured when assembling a plurality of pipes.

종래 청소기의 밀대를 구성하는 파이프의 연결구조는 각 파이프의 일단에 수나사를 구비시키고 타단에 암나사가 구비된 구성이다.The connection structure of the pipe constituting the pusher of the conventional cleaner is a configuration in which a male screw is provided at one end of each pipe and a female screw is provided at the other end.

이같은 상태에서 각 파이프의 수나사와 암나사를 상호 한쌍으로 결합시켜서 소정의 길이를 갖추도록 되어 있다In such a state, the male and female threads of each pipe are coupled to each other to have a predetermined length.

그러나 이같은 상태에서 밀대를 사용하게 되면 각 파이프를 연결하는 수나사와 암나사의 체결력이 느슨해지는 경우가 발생하여 파이프가 자력으로 쉽게 풀리게 되거나 또는 흔들거림이 발생하는 문제가 있다.However, if the use of the push rod in such a state that the tightening force of the male screw and the female screw connecting each pipe occurs, there is a problem that the pipe is easily released by the magnetic force or shake.

따라서 본 고안은 상기와 같은 사정을 감안하여 안출된 것으로, 다수개의 파이프를 조립하였을 시 고정력이 확보되어 흔들거림 없이 연결상태를 안정적으로 유지할 수 있도록 한 파이프 연결구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and its purpose is to provide a pipe connection structure that ensures a stable connection state without shaking when securing a fixed force when assembling a plurality of pipes.

상기의 목적을 달성하기 위한 본 고안의 구체적인 수단은, 파이프를 상호 연결함에 있어서, 하부는 수나사로 형성하고, 상부는 외주면에 축선방향으로 다수의 압입돌기를 형성하여, 이 압입돌기와 수나사 사이에 경사면을 형성하며, 압입돌기의 상면에 플랜지부를 일체로 형성한 수나사뭉치와, 내부에 상기 수나사가 체결되는 암나사를 형성하여 일측에 상기 압입돌기가 압입되는 압입내주면을 형성한 암나사뭉치를 구비하고, 이들 수나사뭉치와 암나사뭉치를 파이프의 일측과 타측에 결착시켜서 된 것을 특징으로 한다.Specific means of the present invention for achieving the above object, in connecting the pipes, the lower portion is formed with a male screw, the upper portion formed a plurality of indentation protrusion in the axial direction on the outer peripheral surface, the inclined surface between the indentation protrusion and the male screw And a male thread bundle having an integrally formed flange portion on an upper surface of the indentation protrusion, and a female thread to which the male screw is fastened therein so as to form a female thread bundle having a press-fitting inner circumferential surface on which the indentation protrusion is press-fitted. These male thread bundles and female thread bundles are characterized by binding to one side and the other side of the pipe.

이하, 첨부된 도면을 참조하여 본 고안의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

제1도 및 제2도에서와 같이 파이프(10)의 일측에는 수나사뭉치(20)가 타측에는 암나사뭉치(30)가 결착되어 있다.As shown in FIG. 1 and FIG. 2, the male thread bundle 20 is attached to one side of the pipe 10 and the female thread bundle 30 is attached to the other side.

상기 수나사뭉치(20)는, 하부는 수나사(21)로 형성하고, 상부는 외주면에 축선방향으로 다수의 압입돌기(23)를 형성하여, 이 압입돌기(23)와 수나사(21)사이에 경사면(22)을 형성하며, 압입돌기(23)의 상면에 플랜지부(24)가 일체로 형성되어 있다.The male thread bundle 20, the lower portion is formed with a male screw 21, the upper portion forms a plurality of indentation protrusions 23 in the axial direction on the outer peripheral surface, the inclined surface between the indentation protrusion 23 and the male screw 21 22 is formed, and the flange part 24 is integrally formed in the upper surface of the indentation protrusion 23. As shown in FIG.

그리고 상기 암나사뭉치(30)는 내부에 상기 수나사뭉치(20)의 수나사(21)가 체결되는 암나사(31)를 형성하고 일측에 상기 압입돌기(23)가 압입되는 압입내주면(32)을 형성하고 있다.And the female screw bundle 30 forms a female screw 31 to which the male screw 21 of the male screw bundle 20 is fastened therein, and forms an indentation inner circumferential surface 32 in which the indentation protrusion 23 is press-fitted on one side thereof. have.

이와 같이 구성된 본 실시예의 작용을 설명한다.The operation of this embodiment configured as described above will be described.

먼저, 제3a도에 도시한 바와 같이 두개의 파이프(10,10)를 연결하려면 한쪽 파이프(10)의 선단에 결착된 수나사뭉치(20)의 수나사(21)를 다른쪽 파이프(10)의 후단에 결착된 암나사뭉치(30)의 암나사(31)에 끼워서 회전시키면, 수나사(21)가 암나사(31)에 나사결합되면서 경사면(22)이 압입내주면(32)에 원활히 진입하게 되고 이어서 압입돌기(32)가 압입내주면(32)에 점차 압착되게 된다.First, as shown in FIG. 3a, in order to connect two pipes 10 and 10, the male screw 21 of the male screw bundle 20 attached to the tip of one pipe 10 is connected to the rear end of the other pipe 10. As shown in FIG. When rotated by inserting into the female screw 31 of the female screw bundle 30 is attached to the male screw 21 is screwed to the female screw 31 while the inclined surface 22 smoothly enters the indentation circumferential surface 32 and then the indentation protrusion ( 32 is gradually pressed against the press-in inner peripheral surface 32.

이같은 상태에서 더욱 파이프(10,10)를 조임하게 되면 제3b도에서와 같이 압입돌기(23)가 압입내주면(32)에 밀착되게 되고, 이 압입돌기(23)가 압입내주면(32)에 투입이 완료되면 수나사뭉치(20)의 플랜지부(24)가 암나사뭉치(30)의 후단에 밀착되게 된다.In such a state, when the pipes 10 and 10 are further tightened, the indentation protrusion 23 is in close contact with the indentation inner circumferential surface 32 as shown in FIG. 3B, and the indentation protrusion 23 is introduced into the indentation inner circumferential surface 32. When this is completed, the flange portion 24 of the male thread bundle 20 is in close contact with the rear end of the female thread bundle 30.

따라서 수나사뭉치(20)의 압입돌기(23)가 암나사뭉치(30)의 압입내주면(32)에 강제 밀착되게 끼워진 상태에서 수나사(21)와 암나사(31)의 체결력이 유지됨으로 자력으로 풀림되는 것을 방지할 수 있다.Therefore, the indentation protrusion 23 of the male thread bundle 20 is loosened by magnetic force while the clamping force of the male screw 21 and the female screw 31 is maintained in a state in which the male screw bundle 20 is pressed against the indentation inner circumferential surface 32 of the female thread bundle 30. You can prevent it.

더욱이 수나사뭉치(20)의 압입돌기(23)가 암나사뭉치(30)의 압입내주면(32)에 강제 끼임된 상태에서 상호 파이프(10,10)의 연결단이 밀착된 상태로 유지함으로 흔들거림을 방지할 수 있다.Furthermore, the indentation protrusion 23 of the male thread bundle 20 is forced to the indentation inner circumferential surface 32 of the female thread bundle 30 so that the connection ends of the pipes 10 and 10 are kept in close contact with each other. You can prevent it.

또한, 본 원 고안은 연결되는 파이프(10)의 외경과 수나사뭉치(20)의 플랜지부(24) 외경의 지름이 같은 지름으로 형성되므로 조립후의 외면둘레가 일정하게 손으로 쥐기에도 편리한 것이다.In addition, the present invention is because the diameter of the outer diameter of the pipe 10 to be connected and the diameter of the outer diameter of the flange portion 24 of the male thread bundle 20 is formed in the same diameter, it is also convenient to grip the outer surface after assembling constantly.

이후 연결된 파이프(10,10)의 분해를 하려면 한쪽 파이프(10)를 잡고 다른 쪽 파이프(10)를 풀림방향으로 강제 회전시키면 암나사뭉치(30)에 삽입된 압입돌기(23)의 끼임이 미끌림으로 해제됨과 함께 수나사(21)가 암나사(31)로부터 풀려지면서 파이프(10,10)는 해체된다.Then, to disassemble the connected pipes (10, 10) by holding one pipe (10) and forcibly rotating the other pipe (10) in the unwinding direction, the pinch of the indentation projections 23 inserted into the female thread bundle 30 is slipped As the male screw 21 is released from the female screw 31, the pipes 10 and 10 are dismantled.

상술한 바와 같이 본 고안에 의하면 파이프의 접속부분에서 압입돌기가 압이 내주면에서 강제 끼임됨과 동시에 그 나사결합의 체결력을 견고히 유지토록 함으로 파이프의 풀림 및 흔들거림을 방지할 수 있다.As described above, according to the present invention, the indentation protrusion at the connection portion of the pipe is forced to be pinched at the inner circumferential surface, and at the same time, the fastening force of the screw connection can be maintained firmly to prevent loosening and shaking of the pipe.
