The present invention relates to an interlocking connection structure for a trailer and, more specifically, to an interlocking connection structure which is installed in a frame body of a trailer. The interlocking connection structure for the trailer of the present invention comprises: a fixed bracket fixed to an end of a frame body; a rotation unit including a pair of rotating connection shafts having one end rotatably and axially coupled to the fixed bracket and a support shaft for connecting the rotating connection shafts; a rotating support unit formed on the support shaft; an elevating driving unit rotatably and axially coupled to the rotation unit; a cylinder bracket fixed to the bottom surface of the frame body; and a cylinder unit having one end fixed to the cylinder bracket and rotating the rotation unit by pressing the rotating support unit. The elevating driving unit installed in a trailer to tow an object is elevated by the cylinder unit and the rotation unit, and is supported by an elastic coil spring after elevation such that stable elevation and support after elevation can be performed.

    본 발명은 트레일러용 연동형 연결구조에 관한 것으로서, 보다 상세하게는 트레일러의 프레임본체에 설치되는 연동식 연결구조로서, 상기 프레임본체의 단부에 고정되는 고정브라켓과, 상기 고정브라켓에 일단이 회동되게 축결합되는 한쌍의 회동연결샤프트와 상기 회동연결샤프트를 연결하는 지지샤프트로 이루어진 회동부와, 상기 지지샤프트에 형성되는 회동지지부와, 상기 회동부에 회전되게 축결합되는 승강주행부와, 상기 프레임본체의 저면에 고정되는 실린더브라켓와, 상기 실린더브라켓에 일단이 고정되고, 상기 회동지지부를 가압하여 상기 회동부를 회전시키는 실린더유닛으로 이루어져, 트레일러에 설치되어 대상물을 견인하도록 된 승강주행부가 실린더유닛과 회동부에 의해 승강되도록 하고, 승강 후 탄성코일스프링에 의해 지지되도록 함으로써, 안정적인 승강과 승강 후 지지가 가능하게 되는 효고가 있다.
