본 고안은 일 부품에 다른 부품을 착탈이 자유롭게 결합할 수 있도록 하는 탄성록크핀에 관한 것으로, 더 자세하게는 양 부품의 체결과 해체를 더욱 용이하게 할 수 있도록 개선한 것에 관한 것이다.The present invention relates to an elastic lock pin that can be detachably attached to other components to one component, and more particularly, to improve to facilitate the fastening and disassembly of both components.
종래에 있어서 독립적으로 제작된 두 부품을 착탈이 자유롭게 결합하는 로크핀(lock pin)으로는 양 부품의 핀공을 관통한 일단부를 좌우측으로 벌리는 것에 의해 이탈이 방지되도록 하는 스필트핀(spilt pin)이나 핀헤드의 타단부에 보조 스필트핀을 결합할 수 있도록 하는 보조핀공을 형성한 것, 또는 일단부 외주에 링홈을 형성하고 안쪽으로 오므려지는 탄성을 갖는 E자형 링을 결합하는 것등이 주로 사용되었다.In the related art, as a lock pin for detachably attaching two parts manufactured independently, a split pin or a pin to prevent separation by spreading one end penetrating the pin hole of both parts to the left and right sides. Forming an auxiliary pin hole for joining the auxiliary split pin to the other end of the head, or forming a ring groove on the outer periphery of one end and joining an E-shaped ring having elasticity to be retracted inwardly .
그러나 상기 종래의 록크핀들에 있어서는 각 부품의 핀공에 핀의 몸체를 투입한 후 보조핀이나 링을 결합하여 핀을 설치하는 작업이나 보조핀이나 링을 벗겨내어 핀을 뽑아내고 각 부품을 분해하는 작업이 꽤나 힘들고 번거롭게 되는 문제가 있게 된다.However, in the conventional lock pins, after inserting the body of the pin into the pin hole of each part, the work to install the pin by combining the auxiliary pin or ring, or to remove the pin by removing the auxiliary pin or ring to disassemble each part There is a problem that is quite difficult and cumbersome.
즉, 보조 스필트핀을 사용하는 경우에는 비교적 강도가 높은 보조 스필트핀을 양측으로 벌리거나 오므리는데에 많은 힘이 들 뿐 아니라 별도의 벤딩공구를 사용해야 하는 문제가 있게 되고, 탄성이 양호한 E자형링을 사용하는 경우에도 마찬가지로 작은 링을 양측으로 벌려 핀몸체의 링홈에 끼우거나 그로부터 이탈시키는 작업이 힘들고 별도의 작업공구를 사용해야 하는 문제가 있게 된다.That is, in case of using the auxiliary split pin, it is not only a lot of force to spread or pinch the relatively high auxiliary split pin to both sides, but also requires the use of a separate bending tool. In the case of using, likewise, it is difficult to insert a small ring to both sides of the ring body of the pin body or to detach it from the pin body and use a separate work tool.
본 고안은 상기 종래의 실정을 감안하여 안출한 것이며, 그 목적은 각 부품에 보다 용이하게 설치할 수 있도록 함은 물론 손쉽게 분해해낼 수 있도록 하는 탄성로크핀을 제공하는 데에 있는 것이다.The present invention has been devised in view of the above-described conventional situation, and an object thereof is to provide an elastic lock pin that can be easily disassembled as well as easily installed on each component.
본 고안은 상기의 목적을 달성하기 위하여 팬헤드에 비틀림스프링을 회동이 자유롭게 설치하는 것을 특징으로 하여, 이하 그 구체적인 내용을 첨부도면에 도시한 한 바람직한 실시예를 통하여 더욱 자세히 설명하면 다음과 같다.The present invention is characterized in that the torsion spring is rotatably installed in the pan head in order to achieve the above object, when described in more detail through one preferred embodiment shown in the accompanying drawings as follows.
즉, 본 고안은 탄성로크핀(1)을 구성함에 있어서 제1도 및 제2도와 같이 각 체결대상 부품(2), (3)에 형성된 핀공(2a), (3a)에 투입되는 핀몸체(10)의 일측에 마련되는 핀헤드(11)의 전후방에 끼움공(12)을 형성하고, 상기 양 끼움공(12)을 통해 양단에 내향절곡부(21)가 형성된 비틀림스프링(20)을 핀 헤드(11)에 회동이 자유롭게 설치하여서 되는 것이다.That is, in the present invention, in forming the elastic lock pin 1, the pin body (2a), (3a) to be inserted into the pin hole (2a, 3a) formed in each of the fastening part (2), (3) as shown in Figs. The fitting hole 12 is formed in front and rear of the pin head 11 provided at one side of the pin 10, and the torsion spring 20 in which the inward bending portion 21 is formed at both ends through the fitting holes 12 is pinned. The rotation is freely provided in the head 11.
도면부호중 미설명부호 30은 연결끈이다.Reference numeral 30 in the drawing denotes a connecting string.
상기와 같이 구성된 본 고안에 있어서는 제1도와 같이 비틀림스프링(20)을 핀헤드(11)쪽으로 젖힌 상태에서 핀몸체(10)를 각 부품(2), (3)의 핀공(2a), (3a)에 투입한 다음 비틀림스프링(20)을 핀몸체(10)쪽으로 회동 시키는 것에 의해 제3도와 같이 탄성로크핀(1)을 각 부품(2), (3)에 견고하게 설치할 수 있게 되는 것이다.In the present invention configured as described above, the pin body 10 is turned into the pin holes 2a and 3a of the respective parts 2 and 3 in a state where the torsion spring 20 is turned toward the pin head 11 as shown in FIG. By rotating the torsion spring (20) toward the pin body (10), the elastic lock pin (1) can be firmly installed on each of the parts (2) and (3) as shown in FIG.
즉, 비틀림스프링(20)은 감는 방향에 따라 그 장력방향이 달라지게 되므로 제 3 도와 같이 설치가 완료된 상태에서의 탄성로크핀(1)은 그의 비틀림스프링(20)이 핀몸체(10)쪽으로의 탄성을 발휘하게 되며, 따라서 탄성록크핀(1)은 이탈의 우려없이 견고하게 각 부품(2), (3)을 고정할 수 있게 된다.That is, since the tension direction of the torsion spring 20 is changed according to the winding direction, the elastic lock pin 1 in the state where the installation is completed as shown in the third degree has the torsion spring 20 toward the pin body 10. The elastic lock pin 1 can be firmly fixed to each of the parts 2 and 3 without fear of detachment.
한편 탄성로크핀(1)을 뽑아내고 각 부품(2), (3)을 분해하고자 할 때는 비틀림스프링(20)을 제3도의 가상선상태와 같이 핀헤드(11)쪽으로 회동시키면 되는 바, 제1도 및 제3도의 가상선상태와 같이 비틀림스프링(20)이 핀헤드(11)쪽으로 회동된 상태에서는 각 부품(2), (3)에 작용하던 비틀림스프링(20)의 탄성이 제거되므로 비틀림스프링(20)이나 핀헤드(11)을 일측으로 잡아당기는 것에 의해 핀몸체(10)를 각 부품(2), (3)의 핀공(2a), (3a)으로부터 손쉽게 뽑아낼 수 있게 된다.On the other hand, when the elastic lock pin (1) is pulled out and the parts (2) and (3) are to be disassembled, the torsion spring (20) can be rotated toward the pin head (11) as shown in FIG. In the state where the torsion spring 20 is rotated toward the pin head 11 as shown in the imaginary line state of FIGS. 1 and 3, the elasticity of the torsion spring 20 acting on each of the parts 2 and 3 is removed. By pulling the spring 20 or the pin head 11 to one side, the pin body 10 can be easily pulled out from the pin holes 2a and 3a of each of the parts 2 and 3.
이상에서와 같이 본 고안은 각 부품(2), (3)의 핀공(2a), (3a)에 핀몸체(10)를 투입한 후 비틀림스프링(20)을 회동시키는 것에 의해 각 부품(2), (3)을 견고하게 결속할 수 있게 되고, 비틀림스프링(20)을 다른 방향의 회동시키는 것에 의해 각 부품(2), (3)을 용이하게 해체할 수 있게 되는 것으로, 본 고안에 의하면 수시로 착탈하여야 하는 각 부품을 결합하거나 조립함에 있어서 그 작업을 수월하게 할 수 있게 되므로 작업시간을 단축할 수 있게 되고 제품의 생산성을 향상시킬 수 있게 됨은 물론 작업비용을 절감할 수 있게 되는 등의 효과를 얻을 수 있게 된다.As described above, according to the present invention, after inserting the pin body 10 into the pinholes 2a and 3a of the respective components 2 and 3, the torsion springs 20 are rotated to rotate the respective components 2. , (3) can be firmly bound, and the components (2) and (3) can be easily dismantled by rotating the torsion spring 20 in different directions. It is possible to facilitate the work in assembling or assembling each component to be detached, thereby reducing the working time, improving the productivity of the product, and reducing the operating cost. You can get it.
