본 발명은 주철관 연결 소켓에 파이프를 연결하는 파이프연결 어셈블리에 관한 것으로, 더욱 상세하게는 소켓에 주철관 등의 파이프를 체결함에 있어 그 작업을 편리하고 신속하게 할 수 있을 뿐만 아니라, 주철관 외에 합성수지관도 쉽게 연결하도록 구성된 파이프연결 어셈블리에 관한 것이다.The present invention relates to a pipe connection assembly for connecting a pipe to a cast iron pipe connecting socket, and more particularly, to fasten the pipe, such as cast iron pipe to the socket, the operation can be convenient and quick, as well as a synthetic resin pipe in addition to the cast iron pipe A pipe connection assembly configured to connect.

본 발명에서의 "파이프"는 주철관과 합성수지관을 통칭하는 것으로 정의한다."Pipe" in the present invention is defined as collectively cast iron pipe and synthetic resin pipe.

종래에도 소켓에 주철관 등의 파이프를 연결하기 위한 어셈블리가 개발되어 왔고 최근에 본 출원인이 특허권자로 되어 있는 국내등록특허 제10-633423호가 특허공보에 개시된바 있다.Conventionally, an assembly for connecting a pipe such as a cast iron pipe to a socket has been developed, and recently, Korean Patent No. 10-633423, in which the applicant is a patent holder, has been disclosed in a patent publication.

상기의 종래기술은 소켓의 주철관 수구와 파이프 사이를 밀폐하는 고무링과, 이 고무링을 눌러주는 압륜과, 파이프를 잡아주는 스파이크와, 이 스파이크를 가압하는 가압링으로 구성된 것으로, 상기와 같은 종래기술은 가압링을 압륜에 체결할 때 다수개의 볼트로 체결하여야 하므로 체결작업이 번거롭고 신속하지 못하며 파이프를 소켓의 주철관 수구에 삽입할 때 어느 정도 삽입되었는지 가늠이 쉽지않아 작 업상 불편한 점이 많았고 주철관보다 외경이 작게 생산되는 합성수지관의 체결은 어려운 문제점이 있었다.The prior art is composed of a rubber ring for sealing between the cast iron pipe outlet of the socket and the pipe, a pressure ring for pressing the rubber ring, a spike for holding the pipe, and a pressure ring for pressing the spike. As the technology requires fastening the pressure ring to the pressure wheel, it is necessary to fasten it with a number of bolts. Therefore, the fastening work is not cumbersome and quick, and it is not easy to estimate how much it is inserted when inserting the pipe into the cast iron pipe outlet of the socket. This small production of synthetic resin pipes had a difficult problem.

본 발명은 상기와 같은 여러 가지 문제점을 해결하기 위하여 압륜과 가압링의 체결구조를 개선하고, 소켓의 내부에 걸림턱을 형성하여 파이프가 수구에 삽입될 때 삽입되는 길이가 한정되게 하여 체결작업을 신속하고 편리하게 한 파이프연결 어셈블리를 제공함에 그 목적이 있다.The present invention improves the fastening structure of the pressure wheel and the pressure ring in order to solve the various problems as described above, and forming a locking jaw in the socket so that the length to be inserted when the pipe is inserted into the water port is limited to the fastening operation The purpose is to provide a pipe connection assembly that is quick and convenient.

상기와 같은 목적을 달성하기 위한 본 발명은 소켓 본체와 고무링과 압륜과 조임구와 가압링이 구비된 것에 있어서, 압륜과 가압링을 체결하는 구조로서 압륜의 상면에 중앙의 관통공과 동심원을 이루는 나사관을 형성하고 가압링에도 상기 나사관과 나사 결합하는 나사관을 형성하여 상기 압륜과 가압링의 체결을 상기 각자의 나사관으로 체결할 수 있게 한 특징이 있다.In order to achieve the above object, the present invention provides a socket body, a rubber ring, a pressure ring, a clamping hole, and a pressure ring, wherein the pressure ring and the pressure ring form a concentric circle with a central through-hole on the upper surface of the pressure wheel. It is characterized in that the formation of a threaded pipe and a screw tube for screwing the screw pipe to the pressure ring to fasten the pressure ring and the pressure ring to the respective screw pipe.

또, 본 발명은 소켓 본체의 내부에 연결되는 주철관이나 합성수지관이 모두 소정의 길이만큼 삽입되면 더 이상 삽입이 되지 않도록 걸림부를 돌출 형성하여서 된 다른 특징이 있다.In addition, the present invention has another feature that is formed by protruding the locking portion so that the cast iron pipe or the synthetic resin pipe connected to the inside of the socket body is inserted by a predetermined length so that no further insertion.

상기와 같은 특징을 지닌 본 발명은 압륜과 가압링 간의 체결작업이 용이하고 그 작업이 신속하게 이루어지며 주철관뿐만 아니라 외경이 주철관보다 작은 합성수지관도 연결할 수 있게 되는 이점이 있다. The present invention having the characteristics as described above has the advantage that the fastening operation between the pressure wheel and the pressure ring is easy and the operation is made quickly, as well as the cast iron pipe can be connected to the synthetic resin pipe smaller than the cast iron pipe.

도 1은 본 발명의 바람직한 실시 예를 나타낸 분해 사시도이고, 도 2는 도 1의 조립상태 단면도이다. 1 is an exploded perspective view showing a preferred embodiment of the present invention, Figure 2 is an assembled cross-sectional view of FIG.

본 발명의 파이프연결 어셈블리는 소켓 본체(10)와 고무링(20)과 압륜(30)과 조임구(40)와 가압링(50)으로 구성된다. Pipe connection assembly of the present invention is composed of the socket body 10, the rubber ring 20, the pressure ring 30, the fastener 40 and the pressure ring (50).

상기 소켓 본체(10)는 그 내부에 주철관뿐만 아니라 외경이 작은 PVC관 등 합성수지관도 걸리는 걸림부(11)가 형성되어 있다. 이 걸림부(11)는 삽입되는 파이프의 선단이 일정 위치에서 걸리도록 하기 위한 것이기 때문에 도 3과 같이 원형 테두리와 같이 형성할 수도 있고, 도 4와 같이 돌기 형상으로 형성할 수도 있으며 그밖에 파이프가 걸리도록 하는 다른 형상으로도 형성할 수 있다. The socket body 10 has a locking portion 11 is formed therein as well as cast iron pipes, synthetic resin pipes such as PVC pipes with a small outer diameter. Since the catching part 11 is intended to catch the tip of the pipe to be inserted at a predetermined position, it may be formed as a circular rim as shown in FIG. 3, or may be formed as a protrusion as shown in FIG. 4. It can also be formed into other shapes.

상기 고무링(20)은 소켓 본체(10)의 입구와 이에 삽입되는 파이프(60)의 외주면 사이를 밀폐하는 역할을 한다.The rubber ring 20 serves to seal between the inlet of the socket body 10 and the outer circumferential surface of the pipe 60 inserted thereto.

상기 압륜(30)은 중앙에 파이프가 관통되는 관통공(31)과 누름부(32)가 형성되고 상면에는 외주면에 수나사부(33a)가 형성된 나사관(33)이 돌출형성되어 있다.The pressure ring 30 has a through hole 31 through which a pipe penetrates in the center and a pressing portion 32, and a screw tube 33 having a male screw portion 33a formed on an outer circumferential surface thereof protrudes.

상기 조임구(40)는 금속으로 탄성을 갖도록 제작되고 절제부(41)를 가지며 파이프()의 외주면을 조여주는 역할을 한다.The fastener 40 is manufactured to have elasticity with a metal, has a cutout portion 41, and serves to tighten the outer circumferential surface of the pipe ().

상기 가압링(50)은 원판형으로 형성되고 중앙에 파이프 관통공(51)이 형성되고 그 주위에 가압부(52)가 형성되며 외주연에 상기 나사관(33)과 나사결합이 가능한 암나사부(53a)가 내주면에 형성된 나사관(53)이 형성되어 있다.The pressure ring 50 is formed in a disk shape, the pipe through-hole 51 is formed in the center and the pressing portion 52 is formed around the female screw portion that can be screwed to the screw tube 33 on the outer periphery The screw pipe 53 in which 53a was formed in the inner peripheral surface is formed.

상기 압륜(30)의 나사관(33)과 상기 가압링(50)의 나사관(53)은 서로 나사체결이 가능하도록 하기 위하여 형성된 것이므로 압륜(30)의 나사관에 암나사부를 형 성하고 가압링(50)의 나사관에 수나사부를 형성할 수도 있다.Since the screw tube 33 of the pressure ring 30 and the screw tube 53 of the pressure ring 50 are formed to be screwed together, form a female thread on the screw tube of the pressure ring 30 and press the ring. The male screw part can also be formed in the screw pipe of (50).

상기 가압링(50)은 나사조립시에 회전을 편리하게 하도록 공구(70)가 삽입되는 공구구멍(54)이 천공되어 있다.The pressure ring 50 is perforated with a tool hole 54 into which the tool 70 is inserted to facilitate rotation during screw assembly.

미설명부호 34는 걸이 볼트이고, 35는 너트이다.Reference numeral 34 is a hook bolt and 35 is a nut.

상기와 같이 구성되는 본 발명은 액체나 기체 등의 유체 도관을 설치할 때 사용되는 파이프연결 어셈블리로서, 소켓 본체(10)의 내부에 형성되어 있는 걸림부(11)에 의해 소켓 본체(10)에 삽입되는 파이프(60)가 적정길이만큼 삽입되기 때문에 삽입이 덜되거나 너무 과도하게 삽입되므로 인한 부실공사를 미연에 방지할 수 있고, 압륜(30)과 가압링(50)이 나사관(33)(53)에 의해 한번에 체결되어 체결작업이 편리하고 신속하게 되어 작업현장에서 아주 요긴하게 이용할 수 있는 유용한 발명이다.The present invention constituted as described above is a pipe connection assembly used when installing a fluid conduit such as liquid or gas, and inserted into the socket body 10 by a catching portion 11 formed inside the socket body 10. Since the pipe 60 is inserted as much as the proper length, less insertion or too much insertion can be prevented due to poor construction, and the pressure ring 30 and the pressure ring 50 are screw pipes 33 and 53. It is a useful invention that can be used very usefully at the work site because the fastening work is convenient and quick as it is fastened at once.
