암플러그(1)는 단부내주면에 암나사부(6)가 형성되고 내측면에 스프링(9)이 외측으로 끼워지는 돌출부(8)가 .형성된 엘보(3)와, 외주면에 수플러그(2)의 몸체(13)의 단부가 걸리는 몸체걸림틱(22)과 볼삽입흠(12)이 형성되고 후단부의 외주면에 상기 암나사부(6)와 결합되는 수나사부(7)가 형성되며 전단부에 상기 수플러그(2)의 푸시부재(19)가 삽입되는 통공(11)이 형성된 결합부재(4)가 일체로 결합되어 있다.The female plug 1 has an elbow 3 formed with a female threaded portion 6 on the inner circumferential surface of the end and a protrusion 8 on which the spring 9 is fitted on the inner surface of the female plug 1, and the male plug 2 on the outer circumferential surface. A body catching tick 22 and a ball insertion flaw 12 are formed on the end of the body 13 and a male screw portion 7 is formed on the outer circumferential surface of the rear end portion to be coupled to the female screw portion 6. A coupling member 4 having a through hole 11 into which the push member 19 of the plug 2 is inserted is integrally coupled.
또 상기 암플러그(1)의 내부에는 상기 스프링(9)에 의해 탄성지지되고 상기 통공(11)을 개폐시키는 밀폐부재(10)가 설치되어 있다.The female plug 1 is provided with a sealing member 10 which is elastically supported by the spring 9 and opens and closes the through hole 11.
수플러그(2)는 내부에 스프링(14),푸시부재(19)가 차레로 삽입된 상테에서 지지부재(20)와 패킹(21)이 차례로 부착고정되고 단부에 원주를 따라 볼(16)이 삽입되는 다수개의 볼삽입통공(24)이 형성되며 외주면에 링(17)이 고정되고 스프링(15)이 끼워지는 몸체(13)와, 상기 스프링(15)에 의해 탄성지지되고 암플러그(1)와의 결합시 상기 링(17)에 의해 이탈이 방지되고 상기 볼(16)을 지지하는 환덮개(18)가 일체로 결합되어 있다.The male plug 2 has a spring 14 and a push member 19 inserted therein, and the support member 20 and the packing 21 are attached and fixed in turn, and the ball 16 is circumferentially attached at the end thereof. A plurality of ball insertion holes 24 to be inserted are formed, and a body 13 to which a ring 17 is fixed to the outer circumferential surface and a spring 15 is fitted, and is elastically supported by the spring 15, and an arm plug 1.

상기의 상태에서 푸시부재(19)가 제1밀폐부재(40)을 밀면 스프링(49)의 압축력이 스프링(45)의 압축력보다 크기때문에 상기 제1밀폐부재(40)는 상기 푸시부재(19)에 밀려 통공(11)을 개방시키게된다.When the push member 19 pushes the first sealing member 40 in the above state, since the compressive force of the spring 49 is greater than that of the spring 45, the first sealing member 40 is the push member 19. Pushed to open the through hole (11).
제3도에서 확인되는 바와같이 상기의 상태에서 제2밀폐부재(44)는 여전히 가스의 흐름을 차단시키고 있기때문에 가스의 유출은 방지된다.As can be seen in FIG. 3, in the above state, since the second sealing member 44 is still blocking the flow of gas, outflow of gas is prevented.
상기의 상태애서 암플러그(31)를 더 삽입시키면 패킹(21)이 결합부재(34)의 전면에 밀착되게됨과 동시에 푸시부재(19)에 의해 밀린 제1밀폐부재(40)가 제2밀폐부재(44)를 밀게된다.If the female plug 31 is further inserted in the above state, the packing 21 is brought into close contact with the front surface of the coupling member 34 and the first sealing member 40 pushed by the push member 19 is the second sealing member. Will push 44.
상기의 결합과정애서 푸시부재(19)가 어느정도의 탄성에 의해 후진되나 스프링(49)의 압축력이 스프링(9)의 압축력보다 크기때문에 상기 푸시부재(19)가 제2밀폐부재(44)를 밀고 상기 제1밀폐부재(40)가 제2밀폐부재(44)를 밀게되어 가스가 수플러그(32)쪽으로 흐르게 된다.In the coupling process, the push member 19 is retracted by some elasticity, but the push member 19 pushes the second sealing member 44 because the compression force of the spring 49 is greater than that of the spring 9. The first sealing member 40 pushes the second sealing member 44 so that the gas flows toward the male plug 32.
상기에서 확인되는 바와같이, 본 고안에 따른 가스플러그는, 스프링들의 압축력의 크기를 스프링(45)보다 스프링(9)이 크게하고,스프링(9)보다 스프링(49)이 크게 한 것에 의해 1차결합시에 푸시부재(19)가 제1밀폐부재(40)를 밀어 통공(11)을 개방시킨 상태에서도 제2밀폐부재(44)는 암플러그(31)의 내부를 밀폐시킨상태에 있기 때문에 암플러그(31)와 수플러그(32)의 체결도중에도 가스의 유출이 방지되게 된다는 것이다.As can be seen from the above, the gas plug according to the present invention is primarily made of a spring 9 larger than the spring 45 and a spring 49 larger than the spring 9. Even when the push member 19 pushes the first sealing member 40 to open the through hole 11 at the time of engagement, the second sealing member 44 is in a state of sealing the inside of the female plug 31. The outflow of gas is prevented even during the engagement of the plug 31 and the male plug 32.
