제1도에는 종래 실린더가 도시되어 있는바, 이는 실린더 본체(1)와, 상기 실린더 본체(1) 내부에 설치되며 일단에 피스톤부(2a)가 형성된 피스톤로드(2)와, 상기 실린더 본체(1)에 소정간격 이격되도록 형성된 제1,2포트(3)(4)로 구성된다.FIG. 1 illustrates a conventional cylinder, which includes a cylinder body 1, a piston rod 2 installed inside the cylinder body 1 and having a piston portion 2a at one end thereof, and the cylinder body ( It is composed of the first and second ports (3) (4) formed to be spaced apart a predetermined interval in 1).
이와 같이 구성된 종래 실린더는 제1포트(3)로 작동유체가 공급되면 피스톤로드(2)가 후진되고 제2포트(4)로 작동유체가 공급되면 피스톤로드(2)가 전진되게 되는 것으로서 실린더 본체(1)의 길이보다 긴 행정거리를 얻을 수 없게 되는 문제점이 있었다.In the conventional cylinder configured as described above, the piston rod 2 is retracted when the working fluid is supplied to the first port 3, and the piston rod 2 is advanced when the working fluid is supplied to the second port 4. There was a problem that the stroke length longer than the length of (1) could not be obtained.
본 고안은 상술한 바와 같이 문제점을 감안하여 안출된 것으로서, 실린더 본체의 길이보다 긴 행정거리를 갖는 실린더를 제공함에 그 목적이 있다.The present invention has been made in view of the problem as described above, the object is to provide a cylinder having a stroke length longer than the length of the cylinder body.
상기의 목적을 달성하기 위하여 본 고안은, 제1, 제2포트가 소정간격으로 형성된 실린더 본체와, 상기 실린더 본체 내부에 슬라이딩 가능하게 설치되며 그 일단에 피스톤부가 형성되 피스톤로드를 구비하여된 실린더에 있어서, 일단에 제3포트가 형성된 피스톤부가 형성되고 타단에 제4포트가 형성된 연결로드가 상기 실린더 본체 내부에 슬라이딩 가능하게 설치되고, 상기 연결로드 내부에, 일단에 피스톤부가 형성된 피스톤로드가 슬라이딩 가능하게 설치됨과 동시에 제1스프링부재에 의해 행정방향과 반대방향으로 탄성바이어스 되도록 설치되어 된 점에 그 특징이 있다.In order to achieve the above object, the present invention provides a cylinder body having a first and second ports formed at predetermined intervals, and slidably installed in the cylinder body, and having a piston part at one end thereof. The piston rod having a third port formed at one end thereof and a connecting rod having a fourth port formed at the other end thereof is slidably installed in the cylinder body, and the piston rod formed at one end of the piston rod slidable inside the connecting rod. At the same time, the first spring member is installed so as to be elastically biased in the opposite direction to the stroke direction.
이하 첨부된 도면을 참조하여 본 고안에 따른 한 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도에는 본 고안에 따른 실린더가 도시되어 있는바, 이는 제1, 제2포트(11)(12)가 소정간격 이격되도록 형성된 본체(10)와, 상기 본체(10) 내부에 슬라이딩 가능하게 설치되며, 일단에 제3포트(22)가 형성된 피스톤부(21)가 형성되고 타단에 제4포트(23)가 형성된 연결로드(20)와, 상기 연결로드(20) 내부에 슬라이딩 가능하게 설치되며 제1스프링부재(40)에 의해 행정방향과 반대방향으로 탄성바이어스 되는 일단에 피스톤부(31)가 형성된 피스톤로드(30)를 구비한다.2 shows a cylinder according to the present invention, which is formed so that the first and second ports 11 and 12 are formed to be spaced apart from each other by a predetermined interval, and are slidable inside the body 10. It is installed, the connecting rod 20 is formed in one end of the piston port 21 is formed with a third port 22 and the fourth port 23 is formed in the other end, and the sliding rod is installed in the connection rod 20 And a piston rod 30 having a piston portion 31 formed at one end elastically biased in a direction opposite to the stroke direction by the first spring member 40.
이와 같이 구성된 본 고안에 따른 실린더는 다음과 같이 작동되는데, 먼저 제1포트(11)로 작동유체가 공급되면 작동유체에 의해 연결로드(20)가 전진하게 되고 연결로드(20)가 전진된 상태에서 상기 작동유체가 상기 연결로드(20)의 제3포트(22)를 통해 공급되어 연결로드(20) 내부에 설치된 피스톤로드(30)의 피스톤부(31)를 밀게됨에 따라 피스톤로드(30)가 제1스프링부재(40)를 밀면서 전진하게 된다. 그리고 후진시에 제2포트(12)로 작동유체를 공급하여 연결로드(20)를 후진시키고, 연결로드(20) 내부에 설치된 피스톤로드(30)는 제1스프링부재(40)의 복원력에 의해 후진되게 된다.The cylinder according to the present invention configured as described above is operated as follows. First, when the working fluid is supplied to the first port 11, the connecting rod 20 is advanced by the working fluid, and the connecting rod 20 is advanced. As the working fluid is supplied through the third port 22 of the connecting rod 20 to push the piston 31 of the piston rod 30 installed in the connecting rod 20, the piston rod 30 The first spring member 40 is pushed forward. Then, when the reverse side is supplied to the working fluid to the second port 12, the connecting rod 20 is reversed, and the piston rod 30 installed in the connecting rod 20 by the restoring force of the first spring member 40 Will be reversed.
제3도에는 본 고안에 따른 실린더의 다른 실시예가 도시되어 있는바, 이는 제1포트(11)가 형성된 실린더 본체(10) 내부에 슬라이딩 가능하게 설치된 연결로드(20)가 제2스프링부재(50)에 의해 행정방향과 반대방향으로 탄성바이어스 되도록 설치되고, 상기 연결로드(20)의 내부에는 피스톤로드(30)가 제1스프링부재(40)에 의해 행정방향과 반대방향으로 탄성바이어스 되도록 설치된다.3 shows another embodiment of a cylinder according to the present invention, in which a connecting rod 20 slidably installed inside a cylinder body 10 in which a first port 11 is formed is provided with a second spring member 50. It is installed so as to be an elastic bias in the opposite direction to the stroke direction, the piston rod 30 is installed inside the connecting rod 20 so as to elastically bias in the opposite direction to the stroke direction by the first spring member (40). .
이와 같이 구성된 본 고안의 다른 실시예는 제1포트(11)로 작동유체가 공급되면 작동유체가 연결로드(20)의 피스톤부(21)를 밀게됨에 따라 연결로드(20)가 제2스프링부재(50)를 밀면서 전진되게 되고, 작동유체가 연결로드(20)의 제3포트(22)를 통해 공급되어 연결로드(20) 내부에 설치된 피스톤로드(30)의 피스톤부(31)를 밀게됨에 따라 피스톤로드(30)가 제1스프링부재(40)를 밀면서 전진되게 된다.In another embodiment of the present invention configured as described above, when the working fluid is supplied to the first port 11, the connecting rod 20 is connected to the second spring member as the working fluid pushes the piston 21 of the connecting rod 20. Since the 50 is pushed forward, the working fluid is supplied through the third port 22 of the connecting rod 20 to push the piston 31 of the piston rod 30 installed inside the connecting rod 20. Accordingly, the piston rod 30 is advanced while pushing the first spring member 40.
그리고 후진시에는 제1포트(11)로 공급되는 작동유체를 중단함으로써 제1, 제2스프링부재(40)(50)의 복원력에 의해 피스톤로드(30)와 연결로드(20)가 후진되게 된다.In the reverse direction, the piston rod 30 and the connecting rod 20 are reversed by the restoring force of the first and second spring members 40 and 50 by stopping the working fluid supplied to the first port 11. .
이상에서 설명한 바와 같이 본 고안 실린더는 실린더 본체 내부에 연결로드와 이 연결로드의 내부에 설치되는 피스톤로드가 설치되어 연결로드가 일차전진된 상태에서 피스톤로드가 더 전진하도록 되어 있으므로 실린더 본체의 길이보다 긴 행정거리를 얻을 수 있게 됨에 따라 제한된 공간에 실린더의 설치가 가능하게 됨과 동시에 소형화가 가능하게 되게 된다.As described above, the cylinder of the present invention has a connecting rod installed inside the cylinder body and a piston rod installed inside the connecting rod, so that the piston rod moves forward in the state where the connecting rod is first advanced. As a long stroke can be obtained, the cylinder can be installed in a limited space and at the same time, it can be miniaturized.
