Description

가스 스프링용 볼소켓{A BALL SOCKET IN THE GAS SPRING}Ball socket for gas spring {A BALL SOCKET IN THE GAS SPRING}

본 발명은 가스 스프링용 볼소켓에 관한 것으로서, 더욱 상세하게는 볼소켓과 볼스터디 간에 분리가 용이하도록 한 가스 스프링용 볼소켓에 관한 것이다.The present invention relates to a gas spring ball socket, and more particularly to a gas spring ball socket to facilitate separation between the ball socket and the ball study.

일반적으로 승용 자동차의 경우, 엔진이 탑재된 엔진룸을 개폐하기 위한 후드와, 화물을 적재할 수 있는 트렁크룸을 개폐시키기 위하여 트렁크 리드가 제공되어 있고, 또한 승합 자동차의 후방에는 승객 또는 화물이 승차 또는 탑재될 수 있는 테일게이트가 제공되어 있으며, 이같은 후드, 리드 및 게이트에는 이들을 용이하게 개폐시키기 위한 가스 스프링이 설치되어 있다.In general, a passenger car is provided with a hood for opening and closing an engine room equipped with an engine, a trunk lid for opening and closing a trunk room in which cargo can be loaded, and a passenger or cargo is carried behind the van. Or there is provided a tailgate that can be mounted, such a hood, lid and gate is provided with a gas spring for easily opening and closing them.

도 1에 도시되어 있는 바와 같이, 승합차의 후방에는 테일게이트(2)가 차체(1)의 후방에 대해 회동식으로 개폐 가능하게 제공되는바, 이 같은 회동 개폐 작동의 용이함을 위해 가스 스프링(10)이 설치된다.As shown in FIG. 1, the tailgate 2 is provided at the rear of the van so as to be able to open and close pivotally with respect to the rear of the vehicle body 1. ) Is installed.

상기 가스 스프링(10)은 밀폐된 저장튜브에 오일과 압축된 질소 가스가 충진되어 있어 돌출된 피스톤 로드(14)를 눌러서 왕복시킬 때 피스톤 로드(14)에 받는 하중을 변화시키는 구조이므로, 금속 스프링, 고무 스프링 등에 비하여 소형 또는 큰 초기하중 값으로 적은 스프링 정수를 낼 수 있으며, 상기한 금속 스프링 등에서 불가능한 압축 또는 신축 방향시 속도를 제어할 수도 있고 충격을 완화할 수 있는 등의 많은 장점을 가진다.Since the gas spring 10 is filled with oil and compressed nitrogen gas in a sealed storage tube, the load applied to the piston rod 14 is changed when the piston rod 14 is reciprocated by pressing. Compared to a rubber spring, a small or large initial load value can produce a small spring constant, and it is possible to control the speed in the compression or expansion direction, which is impossible in the metal spring, etc., and to reduce the impact.

도 2에 도시된 바와 같이, 종래의 가스 스프링(10)의 조립구조는 가스 스프링(10)의 피스톤 로드(14)의 선단 내측에 삽입홀(24)이 형성된 볼소켓(30)이 설치되고, 상기 볼소켓(30)의 삽입홀(24)에는 볼 스터디(20)의 볼(22)이 끼워져 결합되며, 상기 볼 스터디(20)의 나사부(26)는 차체(1)에 체결된다.As shown in FIG. 2, a conventional assembly structure of the gas spring 10 includes a ball socket 30 having an insertion hole 24 formed inside the tip of the piston rod 14 of the gas spring 10. The ball 22 of the ball study 20 is fitted into the insertion hole 24 of the ball socket 30, and the threaded portion 26 of the ball study 20 is fastened to the vehicle body 1.

상기와 같은 종래 방식의 볼 스터디 조립구조에서는, 볼 스터디(20)의 볼(22)이 볼소켓(30)의 삽입홀(24)에 결합된 상태로부터 서로 쉽게 분리되지 않도록 하기 위한 구조로, 상기 볼소켓(30) 삽입홀(24)의 상부 내주면에는 링 삽입홀부(34)를 형성하고 있으며 상기 링 삽입홀부(34)에는 일부가 절단된 C자형의 링(32)이 조립되어 있다. 상기 링(32)은 볼 스터디(20)의 볼(22)이 밀고 들어옴에 따라 하부로 이동하면서 벌어지게 되고, 볼(22)이 완전히 볼소켓(30)의 내부에 안착이 되면 링(32)은 탄성력에 의하여 복원되어 링 삽입홀부(34)의 상부로 이동한다. 상기 이동된 링(32)은 볼 스터디(20)의 볼(22)이 외경 간섭하여 빠질 수 없는 상태를 유지하게 된다. 따라서 가스 스프링의 분리 또는 교체가 필요할 시에 볼 스터디(20)와 볼소켓(30)을 함께 교체하여야 하므로 교체 비용이 많이 소요되는 문제점이 있었다.In the conventional ball study assembly structure as described above, the ball 22 of the ball study 20 is configured to prevent the ball 22 from being easily separated from each other from being coupled to the insertion hole 24 of the ball socket 30, A ring insertion hole portion 34 is formed on the upper inner circumferential surface of the ball socket 30 insertion hole 24, and a C-shaped ring 32 is partially assembled into the ring insertion hole portion 34. As shown in FIG. The ring 32 is opened while moving downward as the ball 22 of the ball study 20 is pushed in. When the ball 22 is completely seated in the ball socket 30, the ring 32 Is restored by the elastic force is moved to the upper portion of the ring insertion hole 34. The moved ring 32 is maintained in a state that the ball 22 of the ball study 20 can not be removed by interference with the outer diameter. Therefore, when the gas spring needs to be separated or replaced, the ball study 20 and the ball socket 30 have to be replaced together, which causes a lot of replacement costs.

본 발명은 상술한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 볼 스터디가 볼소켓에 결합된 후에도 필요에 따라 이들이 용이하게 분리될 수 있도록 함으로서 가스 스프링 교체시 볼소켓을 재활용 가능토록 하고, 이에 따라 가스 스프링의 교체 비용이 절감되는 가스 스프링용 볼소켓을 제공하는데 그 목적이 있다.The present invention is to solve the conventional problems as described above, so that they can be easily separated as needed even after the ball study is coupled to the ball socket so that the ball socket can be recycled when replacing the gas spring, accordingly It is an object of the present invention to provide a gas socket ball socket for reducing the cost of replacing the gas spring.
