본 고안은 밀폐된 실린더 내에서 핀로드의 조작으로 피스톤을 전후진 시켜서 고저조절을 필요로 하는 의료기구나 의자등에 안정하게 설치할 수 있도록 하는 밀폐식 기체 실린더에 관한 것이다.The present invention relates to a hermetically sealed gas cylinder that can be stably mounted on a medical device or a chair that requires high and low adjustment by moving the piston back and forth by manipulating a pin rod in a hermetically sealed cylinder.

종래에는 공기압이 작용하는 실린더 내에 봉입한 액체중에 피스톤을 배치해서 이 피스톤에 의하여 구획되는 가, 나 실상호간을 연통시키는 밸브공을 이 피스톤에 형성하고, 피스톤에 일단을 고정해서 그 타단을 외부에 돌출시킨 로드의 외주 장방형 방향에 파이프를 붙여서 파이프에 피스톤의 밸브공을 개폐시키는 밸브를 형성하고 밸브를 밸브공에 대하여 상대변위가 되도록 구성된 길이 조정식 가스스프링(일본특허 공보, 특개소 50-43379)이 알려져 있으나, (가), (나) 실에는 가스실과 오일실을 구성하고 있을뿐만 아니라, 밸브공을 폐쇄하고 개구하는 구조 및 그 조작에 있어서도 복잡하고 다난(多難)하여 실용적 가치가 미약하였다.Conventionally, a piston is arranged in a liquid enclosed in a cylinder in which pneumatic pressure acts and is divided by this piston, or a valve hole for communicating with each other is formed in this piston, and the other end is fixed to the piston to the outside. A length-adjustable gas spring configured to attach a pipe to the outer circumferential direction of the protruding rod to open and close the valve hole of the piston in the pipe, and to make the valve relatively displaced from the valve hole (Japanese Patent Laid-Open No. 50-43379) However, (a) and (b) the chamber not only constitutes a gas chamber and an oil chamber, but also has a complex and diverse utility value in the structure of closing and opening the valve hole and its operation, and has a poor practical value. .

이와같은 단점을 시정하기 위하여 안출한 본원은 밀폐된 실린더 내부에 피스톤을 안쪽끼우기 하되 피스톤 내측에 밸브핀이 안내될 수 있도록 밸브핀 공을 천공하여서 구동핀으로 하여금 밸브핀을 쉽게 구동하므로서, 소망하는 길이만큼 피스톤 로드를 용이하게 인출하고 인입할 수 있게 하여 의자나 의료기구의 높이를 조정하도록 되어 있는바, 첨부도면에 의하여 구조를 상술하면 다음과 같다.In order to correct this drawback, the present application inserts the piston inside the sealed cylinder, but drills the valve pin ball so that the valve pin can be guided inside the piston, so that the driving pin easily drives the valve pin. The piston rod can be easily drawn out and drawn in length to adjust the height of the chair or the medical device. The structure will be described in detail with reference to the accompanying drawings.

내부에 밸브핀(1)이 안내될 수 있는 밸브핀공(2)과 피스톤로드(3)가 끼워붙임할 수 있는 관삽구(4)를 뚫고 피스톤(5) 하단부에는 와셔(6)와 오링(7)을 안쪽끼우기 하고, 그 선단부에는 관체상의 피스톤 로드(3)를 견고하게 끼워붙임한 다음 중간에 가는 허리부(1')가 형성되고 일단에 와셔(6')가 끼워진 밸브핀(1)을 밸브핀공(2)내에 집어넣어서 피스톤(5)을 실린더(8) 내부에 안쪽끼우기한 구조이다.Drill a valve pin hole (2) through which the valve pin (1) can be guided and a pipe insertion hole (4) into which the piston rod (3) can be fitted, and a washer (6) and an o-ring (7) at the lower end of the piston (5). ), The end of which is firmly fitted with a tubular piston rod (3), and a thin waist (1 ') is formed in the middle, and the valve pin (1) with the washer (6') fitted at one end. The piston 5 is inserted into the valve pin hole 2 and the piston 5 is fitted inside the cylinder 8.

도면중 미설명부호, 9는 통기구, 10은 마개, 11은 기체인입구, 12는 체크볼, 13은 구동핀, 14는 부쉼, 15는 파이프부쉼, (a)와 (b)는 기밀실이다.In the drawings, reference numeral 9 denotes a vent, 10 a stopper, 11 a gas inlet, 12 a check ball, 13 a driving pin, 14 a swell, 15 a pipe swell, and (a) and (b) are airtight chambers.

이와같이 구성된 본 고안은 기체인입구(11)로 가스나 기타 기체를 인입하게 되면 기체는 실린더(8) 내부에 충만되어서 압축하게 되는데, 구동핀(13)을 가압하게 되면 구동핀(13)이 밸브핀(1)을 밀어내기 때문에, 밸브핀(1)은 체크볼(12)쪽으로 후진하면서 밸브핀(1)의 가는 허리부(1')가 와셔(6)과 오링(7) 사이에 위치하여 (a)의 기밀실과 밸브핀공(2)이 서로 개통되게 되므로 (a)의 기밀실에 충만되어 있는 압축기체는 통기구(9)를 거쳐서 (b)의 기밀실로 교류하게 된다.When the gas or other gas is introduced into the gas inlet 11, the present invention is configured such that the gas is filled in the cylinder 8 to be compressed. When the driving pin 13 is pressed, the driving pin 13 is a valve pin. (1) pushes the valve pin 1 back toward the check ball 12 while the thin waist 1 'of the valve pin 1 is positioned between the washer 6 and the O-ring 7 ( Since the airtight chamber of a) and the valve pin hole 2 are opened to each other, the compressor body filled in the airtight chamber of (a) exchanges with the airtight chamber of (b) via the vent 9.

반대로 구동핀(13)을 가압하지 아니하게 되면, (a)의 기밀실에 충만되어 있는 압축공기의 압력에 의하여 와셔(6')를 압상하게 되므로 밸브핀(1)은 원위치로 복귀됨과 동시에 통기구(9)를 폐쇄시키게 된다.On the contrary, if the driving pin 13 is not pressurized, the washer 6 'is pressed by the pressure of the compressed air filled in the airtight chamber of (a), so that the valve pin 1 returns to its original position and at the same time the vent hole ( 9) will be closed.

따라서 본 고안을 의자나 의료기구등에 설치하였을 시에는 구동핀(13)만 가압하여서 피스톤로드(3)의 높이를 임의로 손쉽게 조절할 수 있으므로 사용하기에 편리하고 안전하다.Therefore, when the present invention is installed in a chair or a medical device, it is convenient and safe to use because it can easily adjust the height of the piston rod 3 easily by pressing only the driving pin 13.
