Opening and closing apparatus of side door for loading box of truck
The present invention relates to an opening and closing apparatus for a side door of the cargo bed of a truck, which opens and closes a side door by enabling the side door of a loading box of a truck to be folded or unfolded by being divided into an upper door and a lower door to be connected through a link. The opening and closing apparatus for a side door of a truck's cargo bed can improve availability of peripheral space. The opening and closing apparatus for a side door of a truck's cargo bed comprises: two reciprocating cylinders installed to correspond to each other in the upper part of the front or the rear of a truck's cargo bed; a chain gear installed in the upper part of the front or the rear of the cargo bed and rotating according to the operation of the reciprocating cylinder, thereby promoting the opening and closing of the side door in which the upper door is connected to a rotation shaft; a connection member connected to the chain gear and a piston of the reciprocating cylinder and rotating the chain gear according to the operation of the piston; a guide member guiding the opening and closing while supporting the side door as one side is connected to the door frame by a hinge and the other side is connected to a lower end of the lower door of the side door by the hinge; and a locking member including a fixing roller and a fixing guide. The fixing roller is installed at a lower end of the side door. The fixing guide is installed in the lower part of the door frame and maintains a closed state of the side door by accommodating the fixing roller.
본 발명은 화물차의 적재함의 측면도어가 링크를 통해 결합되게 상부도어 및 하부도어로 분할되어서 접힘 또는 펼쳐짐에 의해 상기 측면도어가 개폐되게 하는 차량 적재함의 측면도어 개폐장치에 관한 것으로, 상기 적재함의 전방 또는 후방의 상부에 서로 대응하여 설치된 두 개의 왕복 실린더; 상기 적재함의 전방 또는 후방의 상부에 설치되어서 상기 왕복 실린더의 작동에 따라서 회전함으로써, 상기 상부도어가 회전축에 결합된 상기 측면도어의 개폐를 조장하는 체인기어; 상기 왕복 실린더의 피스톤과 상기 체인기어와 결합되어서, 상기 피스톤의 작동에 따라서 상기 체인기어가 회전되게 하는 연결부재; 일측은 도어프레임에 힌지결합되고 타측은 상기 측면도어의 하부도어의 하단부에 힌지결합되어서 상기 측면도어를 지지하면서 개폐를 안내하는 가이드부재; 및 상기 측면도어의 하단부에 설치된 고정 로울러와, 상기 도어프레임의 하부에 설치되어서 상기 고정 로울러를 수용하여 상기 측면도어의 닫힘 상태가 유지되게 하는 고정 가이드를 구비한 잠금부재;를 포함하여 구성된다.
