The invention provides a pure rolling steering trapezoidal mechanism for a transport trailer. The pure rolling steering trapezoidal mechanism is a six-connection-rod mechanism formed by a fixing rod, a pair of connection frame rods, a pair of sliding blocks and a connection rod. In particular, the fixing rod is parallel to the connection rod, and the sliding blocks are symmetrically hinged to the two ends of the connection rod and slide along the Ackerman locus; the connection frame rods are connected between the ends of the fixing rod and the sliding blocks respectively and formed by welding turning shafts and guide rods. The turning points of the turning shafts are connected with the ends of the fixing rod. The tail ends of the turning shafts are connected with a front wheel through supports. The guide rods slide in holes in the sliding blocks. According to the pure rolling steering trapezoidal mechanism, an Ackerman principle serves as a theoretical basis, angle compensation is achieved through the six-connection-rod structure additionally provided with the sliding blocks, a traction rod is adopted to drive the connection rod to rotate around the fixing rod, the connection rod drives the sliding blocks to walk along the locus, the sliding blocks drive the connection frame rods to rotate, and the front wheel is fixed to the connection rod so as to obtain the right turning angle, so that the steering mechanism can achieve pure rolling in a real sense.
