Description

금속관 압착 체결구조 { a pipe jointing structure }{A pipe jointing structure}

본 고안은 스테인레스관이나 동관 등 소성 변형되는 한 쌍의 금속관을 압착 체결할 수 있도록 하는 금속관 압착 체결구조에 관한 것으로, 더 자세하게는 양 금속관의 결속을 위한 금속가압링과 기밀을 유지하는 고무밀폐링을 구비하는 것에 관한 것이다.The present invention relates to a metal tube crimping fastening structure that can crimp a pair of plastically deformed metal pipes such as stainless steel pipes or copper pipes, and more specifically, a metal pressure ring for binding both metal pipes and a rubber sealing ring for maintaining airtightness. It relates to having a.

일반적으로 주택이나 건물의 상수도관, 또는 그 밖의 유체 이송용으로 널리 사용되고 있는 스테인레스관이나 동관 등의 금속관은 그 두께가 얇아서 나사절삭에 의한 접속이나 용접접속이 용이하지 않고, 용접 가열로 발생되는 금속조직의 변화와 열응력에 의한 내식성 저하의 문제가 있기 때문에 압착의 방법으로 체결하는 예가 많다.In general, metal pipes such as stainless steel pipes and copper pipes, which are widely used for water supply pipes of houses, buildings, or other fluids, are thin in thickness and are not easily connected or welded by screw cutting. Since there is a problem of lowering the corrosion resistance due to changes in the structure and thermal stress, there are many examples of fastening by pressing method.

상기 금속관의 압착 체결구조는 제1금속관의 체결측 내부에 고무밀폐링과 금속가압링을 설치하고 제1금속관의 체결측에 제2금속관을 삽입한 후 제1금속관 체결측을 압착공구로 가압하는 형태의 것이 주로 사용되고 있는 실정이며, 이러한 금속관 압착 체결구조에 있어서 압착공구로 제1금속관 체결측을 압착하게 되면 금속가압링이 제1금속관을 누르게 되어 제1금속관과 제2금속관을 체결하게 되는 동시에고무밀폐링이 기밀을 유지하게 된다.In the crimping fastening structure of the metal pipe, a rubber sealing ring and a metal pressure ring are installed inside the fastening side of the first metal pipe, the second metal pipe is inserted into the fastening side of the first metal pipe, and then the first metal pipe fastening side is pressed with a crimping tool. In this type of metal pipe crimping structure, when the first metal pipe fastening side is crimped with a crimping tool, the metal pressure ring presses the first metal pipe, thereby joining the first metal pipe and the second metal pipe. Rubber sealing ring keeps airtight.

그런데 도 1a에서 도 1d에 도시한 바와 같은 종래의 금속관의 압착 체결구조에 있어서는 제1금속관(10)과 제2금속관(20) 사이의 기밀을 유지하는 고무밀폐링 (30')의 단면형상이 원형으로 되어 있고, 제1금속관(10)과 제2금속관(20)을 체결하는 금속가압링(40')의 단면형상이 장방형으로 되어 있었기 때문에 금속가압링(40')에 의한 체결력이 좋지 않을 뿐 아니라 외부 충격에 의해 도 1c와 같이 양 금속관 (10)(20)의 체결부위가 인장되었다가 도 1d와 같이 원위치로 복귀하게 되면 고무밀폐링(30')에 의한 기밀 유지가 제대로 이루어지지 않게 되는 문제가 있었다.However, in the conventional crimping structure of the metal tube as shown in FIG. 1D in FIG. 1D, the cross-sectional shape of the rubber sealing ring 30 'which maintains the airtightness between the first metal tube 10 and the second metal tube 20 is different. Since the cross-sectional shape of the metal pressing ring 40 'connecting the first metal tube 10 and the second metal tube 20 is rectangular, the clamping force of the metal pressing ring 40' is not good. In addition, when the fastening portion of both metal pipes 10 and 20 is tensioned as shown in FIG. 1C by an external impact and then returned to its original position as shown in FIG. 1D, airtightness is not properly maintained by the rubber sealing ring 30 '. There was a problem.

본 고안은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 제1금속관과 제2금속관이 보다 견고하게 체결될 수 있도록 함은 물론 외부 충격에 의해 양 금속관이 인장된 후 원위치로 복귀되더라도 기밀이 유지될 수 있도록 하는 금속관의 압착 체결구조를 제공하는 데에 있는 것이다.The present invention has been devised in view of the conventional situation as described above, and its purpose is to allow the first metal pipe and the second metal pipe to be more firmly fastened, as well as return to the original position after both metal pipes are tensioned by an external impact. It is to provide a crimping fastening structure of the metal tube so that even if it is kept confidential.

The metal pressure ring (40) formed inside the fastening side of the first metal pipe (10), the second metal pipe (20) is inserted into the fastening side of the first metal pipe (10), and then the first metal pipe (10). 2) The rubber sealing ring on the fastening side has a form in which two places between the first contact portion 31 and the second contact portion 32 and between the second contact portion 32 and the metal pressure ring 40 are pressed with a crimping tool.

도 4에서 도 4d까지에 도시한 본 고안의 다른 실시예는 공지의 금속가압링 (50)과 제1접촉부(31)와 제2접촉부(32)를 갖는 장방형 단면형상의 고무밀폐링(30), 그리고 내측 바깥쪽 둘레에 경사면(41)을 형성한 금속가압링(40)을 제1금속관(10)의 체결측 내부에 설치하고, 제1금속관(10)의 체결측에 제2금속관(20)을 삽입한 후 제1금속관(10) 체결측의 고무밀폐링 제1접촉부(31)와 제2접촉부(32) 사이의 한 곳을 압착공구로 가압한 형태를 갖는다.Another embodiment of the present invention shown in Figures 4 to 4d is a rectangular cross-sectional rubber sealing ring 30 having a known metal pressing ring 50, the first contact portion 31 and the second contact portion (32) And a metal pressure ring 40 having an inclined surface 41 formed on the inner outer circumference inside the fastening side of the first metal pipe 10, and the second metal pipe 20 on the fastening side of the first metal pipe 10. After inserting the first metal pipe 10, the rubber sealing ring on the fastening side of the first contact portion 31 and the second contact portion 32 has a form in which the pressing tool.

본 고안에 있어서 제2금속관(20)이 삽입된 제1금속관(10) 체결측에 대한 가압개수 및 가압형태는 도시된 실시예들에만 국한되지 않고 예측 가능한 다른 개수 및 형태로 변형 실시될 수 있음은 물론이며, 도면부호중 미설명부호 11은 받침단턱이다.In the present invention, the number of pressurizations and pressurization forms on the fastening side of the first metal pipe 10 into which the second metal pipe 20 is inserted may be modified to other predictable numbers and shapes without being limited to the illustrated embodiments. Of course, reference numeral 11 in the drawing is a support step.

상기와 같이 구성된 본 고안에 있어서 압착공구를 통해 제1금속관(10)을 가압하게 되면 금속가압링(40)(50)이 제2금속관(20)의 외표면을 눌러 변형시키게 되면서 양 금속관(10)(20)이 체결되며, 양 금속판(10)(20)에 외력이 가해지게 되더라도 특히 경사면(41)이 형성된 금속가압링(40)을 통해 제2금속관(20)의 유동이 방지될 수 있게 되므로 더욱 견고한 체결상태를 유지할 수 있게 된다.In the present invention configured as described above, when the first metal pipe 10 is pressed through the crimping tool, the metal pressure rings 40 and 50 are pressed and deformed by pressing the outer surface of the second metal pipe 20. (20) is fastened so that the flow of the second metal pipe 20 can be prevented, especially through the metal pressure ring 40 in which the inclined surface 41 is formed even when external force is applied to both the metal plates 10 and 20. Therefore, a more secure fastening state can be maintained.
