The present invention relates to a two-stage covering device for a truck loading box. The two-stage covering device for a truck loading box comprises: first covering units (10) which are installed to be rotatable on first axle fixing units (101a) formed, respectively, on an upper end of both side walls of the truck loading box; first driving means (20) which are installed on both sides of the loading box, respectively, to rotate the first covering units (10), respectively; second covering units (30) which are installed to be rotatable on second axle fixing units (101b) formed on an upper end of each first covering unit (10); and second driving means (40) which are installed on one side of each first covering unit (10) to rotate the second covering unit (30), respectively. According to the present invention, the two-stage covering device for a truck loading box comprises a covering unit opened and closed in two stages on both side walls of the truck loading box while opening and closing angles can be individually adjusted for the covering unit of each stage to facilitate opening and closing of the covering unit even in a narrow space and enable stable closing through the opening and closing angle adjustment of each covering unit even when interference is generated between loaded objects and the covering unit according to the loaded state of the loaded objects, thereby preventing the loaded objects from falling.
본 발명은 화물차 적재함용 2단형 덮개장치에 관한 것으로서, 화물차의 적재함 양 측벽 상단에 각각 형성된 제1축잡이부(101a)에 회동 가능케 설치된 제1덮개부(10); 적재함의 양측에 각각 설치되어 제1덮개부(10)를 각각 회동시키는 제1구동수단(20); 각 제1덮개부(10)의 상단부에 형성된 제2축잡이부(101b)에 회동 가능케 설치된 제2덮개부(30); 각 제1덮개부(10)의 일측에 설치되어 제2덮개부(30)를 각각 회동시키는 제2구동수단(40)을 포함한다. 본 발명에 따르면, 화물차 적재함의 양 측벽에 2단으로 개폐되는 덮개부를 구성하되, 각 단 덮개부의 개별적인 개폐 각도 조절이 가능케 함으로써 협소한 공간에서도 덮개부의 개폐가 용이하며, 적재물의 적재 상태에 따라 적재물과 덮개부 간에 간섭이 발생하더라도 각 덮개부의 개폐 각도 조절을 통해 안정적인 닫힘이 가능케 됨으로써 적재물의 낙하를 방지할 수 있는 효과가 있다.
