본 발명은 강력범의 퇴치나 고귀한 인명 및 재산을 보호하기 위하여 사용될 수 있는 안전 분사기에 관한 것이다.The present invention relates to a safety injector that can be used to combat violent criminals or to protect noble lives and property.

종래의 안전 분사기는 제1도에 도시된 바와같이 그 요부가 일측에 압력용기(1)가 나합고정되는 고정부재(2)의 중심가이드구멍(2a)에 스프링(3)이 탄지된 공이(4)를 내설하고, 고정부재(2)의 가이드구멍(2a) 하부엔 안내경사공(2b)을 형성하며, 그 단부엔 고무링(5)이 삽착되고 분사공(6a)이 형성된 별도의 안내파이프(6)가 끼워져 이루어진다.As shown in FIG. 1, the conventional safety injector has a ball 4 in which the spring 3 is supported in the center guide hole 2a of the fixing member 2, in which the recessed portion of the pressure vessel 1 is fixed to one side thereof. ), A guide sloping hole (2b) is formed in the lower portion of the guide hole (2a) of the fixing member (2), and a separate guide pipe having a rubber ring (5) is inserted at the end thereof and the injection hole (6a) (6) is fitted.

이와같이 안전 분사기는 방아쇠(7)를 당기면 방아쇠(7)의 일측단이 공이(4)의 단부를 밀어주어 공이(4)가 전진하면서 예리한 단부(4a)가 압력용기(1)의 단부를 찌르고 압력용기(1)가 개방되어 압력용기(1)로부터 분사되는 압축가스는 순식간에 중심 가이드구멍(2a), 안내경사공(2b), 안내파이프(6)의 분사공(6a) 및 고무링(5)을 경유, 몸통(8) 내부를 거쳐 외부로 분사되게 되어 있는바, 이때 통상적으로 몸통(8) 내부엔 분말 약제가 내장되어 있어 압축가스가 배출되면서 분말약제가 함께 분사되게 된다.In this way, when the safety injector pulls the trigger (7), one end of the trigger (7) pushes the end of the ball (4), while the ball (4) is advanced, the sharp end (4a) poke the end of the pressure vessel (1) Compressed gas ejected from the pressure vessel 1 by opening the container 1 is quickly discharged into the center guide hole 2a, the guide inclined hole 2b, the injection hole 6a of the guide pipe 6 and the rubber ring 5 Through), to the outside through the body (8) is to be sprayed to the outside, at this time, the powder (8) is usually embedded in the body (8) is injected with the powdered drug while the compressed gas is discharged.

그러나 전술한 안전 분사기는 방아쇠(7)를 작동시켜 공이(4)가 압력용기(1)를 개방시키면, 압력용기(1) 내부에 있던 모든 압축가스는 일시에 외부로 분사되므로 단지 1회에 한하여 사용할 수 밖에 없어 다수의 범인퇴치나 보안용으로는 적합하지 아니하고 여러번 사용할 수 없으므로 내부의 압력용기(1)나 분마약제를 사용후엔 바로 교체해 주어야만 하는 불편한 점이 있다. 또한 사용한후엔 안내파이프(6) 및 고무링(5)의 하부외주연엔 내부압력과 구조적인 문제점으로 인하여 내부의 분말 약제가 이들 주위에 남아 있게 되어 약제의 낭비는 물론 비경제적인 문제점이 있다.However, when the above-mentioned safety injector operates the trigger 7 and the ball 4 opens the pressure vessel 1, all the compressed gas inside the pressure vessel 1 is injected to the outside at a time, so only once Since it is not suitable for a large number of criminals or for security purposes and cannot be used many times, it is inconvenient to replace the internal pressure vessel (1) or powdered drug immediately after use. In addition, due to internal pressure and structural problems in the lower outer periphery of the guide pipe (6) and the rubber ring (5) after use, the internal powdered drug remains around them, and there is a waste of drugs as well as an uneconomical problem.

이하 본 발명의 작용 및 효과에 대하여 살펴보고자 한다.Hereinafter, the operation and effects of the present invention will be described.

우선, 안전 분사기를 사용하는 경우 방아쇠(7)를 당기면, 방아쇠(7)의 일측단부는 작동핀(15)을 수평가압 이동시켜 작동핀(15)의 소경부(39)는 체크밸브(13)의 보올(31)을 가압하고 보올(31)은 공이 (12)를 밀어 공이(12)의 경사단부(27)는 입력용기(1)의 입구부를 뚫는 동시에 압력용기(1) 내부에 있던 고압가스는 누출되면서 순간적으로 공이(12)의 요공(31) 및 개방부(30)나 공이내장공(18)을 경유, 보올(31)과 0링(37) 사이의 간극과 체크밸브(13)의 중심공(33), 통공(38), 밸브내장부(19)의 여유공간, 경사공(23) 및 밸브체(26)를 거쳐 몸통(8) 내부에 내장되어 있는 분말약제와 함께 노즐공(44)을 통하여 외부로 분사된다. 이때 밸브체(26)는 다수의 절결단부(26)가 불거져 나오면서 개방되어 압축가스가 밸브체(26)를 통과하게 된다.First, in the case of using the safety injector, when the trigger 7 is pulled, one side end of the trigger 7 moves the pressure pin 15 horizontally so that the small diameter 39 of the actuating pin 15 is the check valve 13. Pressurizes the bowl 31 and the bowl 31 pushes the ball 12 so that the inclined end 27 of the ball 12 penetrates the inlet of the input container 1 and at the same time the high-pressure gas inside the pressure container 1 The leak is instantaneously through the hole 31 and opening 30 or the ball embedded hole 18 of the ball 12, the gap between the bowl 31 and the 0 ring 37 and the check valve 13 The nozzle hole together with the powdered medicine contained inside the body 8 through the center hole 33, the through hole 38, the clearance of the valve inner part 19, the inclined hole 23 and the valve body 26, Through 44). At this time, the valve body 26 is opened while a plurality of cutout portions 26 are blown out so that the compressed gas passes through the valve body 26.

또한 방아쇠(7)의 가압력을 해제하면 원위치되면서 작동핀(15)은 스프링(14) 에 의하여 후퇴하고, 스프링(11)에 탄지된 공이(12)도 후퇴하여 보올(31) 역시 후퇴하게 되며, 보올(31)과 링(37)은 가압접촉되고 상호 기밀유지가 이루어져 압력용기(1) 내부에 있던 고압가스의 배출은 중지되며, 통공(38), 경사공(23) 및 밸브체(26)를 통한 고압가스의 배출이 멈추게 되어 밸브체(26)는 자체 탄성력에 의하여 원위치되고 밸브체(26)으 폐쇄가 이루어지는 동시에 노즐공(44)을 통한 가스분사가 멈추게 된다.In addition, when the pressing force of the trigger 7 is released, the operation pin 15 is retracted by the spring 14 while being in its original position, and the ball 12 supported by the spring 11 is also retracted so that the bowl 31 is also retracted. The bowl 31 and the ring 37 are in pressure contact with each other, and the airtightness is mutually maintained so that the discharge of the high pressure gas inside the pressure vessel 1 is stopped, and the through hole 38, the inclined hole 23, and the valve body 26 are closed. The discharge of the high-pressure gas through the stop is stopped, the valve body 26 is returned to its original position by its elastic force and the valve body 26 is closed, and at the same time the gas injection through the nozzle hole 44 is stopped.

따라서 전술한 동작을 반복하여 고압용기(1)내에 고압가스가 저장되어 있는 한 여러번에 걸쳐 안전분사기를 사용할 수 있다. 또한 고정부재(10)에 장착된 밸브체(26) 주위의 구조가 단순한 형태로 이루어져 몸통(8) 내부의 분말약재가 주위에 남아있게 될 염려가 전혀 없다.Therefore, the above-described operation can be repeated to use the safety sprayer as many times as long as the high-pressure gas is stored in the high-pressure container 1. In addition, since the structure around the valve body 26 mounted on the fixing member 10 has a simple shape, there is no fear that the powdered medicine inside the body 8 will remain around.

이상 살펴본 바와같이, 본 발명인 안전 분사기는 공이(12)와 작동핀(15)사이에 체크밸브(13)를 내장하여 고압용기(1) 내부에 고압가스가 있는 수회에 걸쳐 사용이 가능하고 수회에 걸쳐 완전한 분사작동이 이루어진 후에도 몸통(8) 내부 구석에 분말약제가 남아있지 않게 되며, 압력용기(1)를 자주 교체하지 아니하여도 되는 편리한 점이 있는 동시에 구조적으로 안정되고 보다 경제적이며 효율적으로 사용될 수 있는 장점을 갖는다.As described above, the present invention is a safety injector can be used for several times with a high-pressure gas inside the high-pressure container (1) by the built-in check valve 13 between the ball 12 and the operating pin (15) Even after complete spraying operation, no powdered chemical remains in the inner corner of the body (8), and there is a convenience that does not require frequent replacement of the pressure vessel (1) and can be used structurally stable, more economically and efficiently. That has the advantage.
