The objective of the present invention is to provide a pin-jig for supporting a weight material, which is provided with uniform height-adjustable repulsive force and has high durability. The pin-jig for supporting a weight material in accordance with the present invention is a pin-jig for supporting a weight material, of which an inner cylinder is vertically inserted into an outer cylinder, such that the position of the inner cylinder can be changed in a vertical direction. The pin-jig for supporting a weight material is characterized by comprising: a hollow rod-shaped guide frame including a guide rod having an upper surface with a sealed upper end portion and a lower fixing plate coupled to a lower end portion of the guide rod, and configured to be inserted into the outer cylinder; a movable bundle including a support plate formed on an lower end portion thereof to support a lower end of the inner cylinder, formed in a sleeve shape surrounding the guide rod, and coupled to the guide frame to be able to move in a vertical direction; and a spring which supports the weight of the inner cylinder when the movable bundle moves up and down, wherein the spring is positioned in the inner space of the guide rod, and has an elastic body of which stress in accordance with deformation is uniformly maintained.
본 발명은 일정한 높낮이 조절 반발력을 가지면서 내구성이 높은 중량물 지지용 핀지그를 제공하는 것을 목적으로 하는 것으로, 본 발명에 따른 중량물 지지용 핀지그는, 지면에 직립되게 세워지는 외통의 내부로 내통이 수직하게 삽입되어 상기 내통의 위치가 상하로 변경될 수 있는 중량물 지지용 핀지그에 있어서, 중공의 봉형상으로 상단부는 밀폐된 상부면을 갖는 가이드봉과 상기 가이드봉의 하단부에 결합되어 있는 하부고정판으로 이루어져, 상기 외통 내부에 삽입되는 가이드프레임; 하단부에는 지지판이 형성되어 상기 내통의 하단을 지지하며, 상기 가이드봉을 감싸는 슬리브 형태로 형성되어 상기 가이드프레임에 상하로 이동되도록 결합되는 가동뭉치; 및 상기 가동뭉치의 상하 이동시 상기 내통의 중량을 받쳐 지지하는 스프링;을 포함하되, 상기 스프링은 상기 가이드봉의 내부 공간에 위치하며, 변형에 따른 탄성체의 응력이 항상 일정한 스프링인 것을 특징으로 한다.
