The inclined plates (7) with (6) are connected to each other, the inclined plates (7) are attenuated by being connected to each other via a spring (9) installed on both sides about the spring hinge connection (8) of the lower housing (3) A damper 10 is provided between one inclined plate 7 and the spring hinge connecting portion 8.
본 발명의 일실시예에서는 양쪽 경사판(7)들 사이에 설치되는 스프링(9)은 4개로 도시되어 있지만 필요에 따라 그 설치 갯수는 다양하게 가감 설치할 수 있으며, 감쇠용 댐퍼(10)도 1개를 설치하였지만 도 6과 같이 양쪽으로 설치할 수도 있음은 물론이다.In an embodiment of the present invention, four springs 9 installed between both inclined plates 7 are illustrated as four, but if necessary, the number of installations can be variously added or subtracted, and a damper 10 for damping is also provided. It is installed but can also be installed in both sides as shown in FIG.
이어 본 발명의 작용원리를 설명하면, 도 2에 도시된 바와 같이 하부하우징(3)은 기기의 기초바닥에 보울트(11)와 같은 체결수단을 매개로 고정되며, 상부하우징(2)에 접하는 힌지 연결축(5)을 꼭지점으로 설치되는 경사판(7)들은 스프링(9)과 볼베어링(6)등을 매개로 하부하우징(3)에 설치되는데, 이 경사판(7)은 평상시 기기의 무게와 스프링(9)의 탄성 인장력이 평형을 이루는 점에서 수평면과 경사를 유지 위치하게 된다.Next, the operation principle of the present invention, as shown in Figure 2, the lower housing (3) is fixed to the base of the machine by means of fastening means such as bolts 11, the hinge in contact with the upper housing (2) The inclined plate (7), which is installed at the vertex of the connecting shaft (5), is installed in the lower housing (3) via the spring (9) and the ball bearing (6). At the point where the elastic tensile force of 9) is in equilibrium, the horizontal plane and the slope are maintained.
