The invention relates to an uplift type trailer frame with the radian; the frame comprises a supporting frame and a traction rod, the supporting frame comprises two symmetrically-arranged arc-shaped rods, the arc-shaped rods gradually uplift and extend from bottom to top to form an upward arch, and the two arc-shaped rods gradually get close in the uplift and extension process and are connected at the top ends; a first cross rod and a straight rod are arranged between the two arc-shaped rods, the first cross rod is connected to the middles of the two arc-shaped rods, and the straight rod is vertically arranged between the connecting position of the two arc-shaped rods and the first cross rod; the traction rod is arranged at the front end of the supporting frame and located on the extension line of the straight rod, and a wearable traction piece is arranged at the front end of the traction rod. According to the invention, the arc-shaped rods which are gradually raised are adopted, which is more in line with ergonomics, and a tractor is more labor-saving during traction; the arc-shaped surface defined by the supporting frame can form a triangular space for the traction person to lift legs between the lower limbs of the traction person and the trailer, standing posture traction can be achieved, prone posture traction can also be achieved so as to meet the use requirements of narrow areas and special environments, and functionality is higher.

    本发明公开一种具有弧度的上扬式拖车车架,其包括支撑架及牵引杆,支撑架包括两根对称设置的弧形杆,弧形杆由下至上逐渐上扬延伸并形成向上的拱形,两根弧形杆上扬延伸的过程中逐渐靠拢,并在顶端连接;两根弧形杆之间设第一横杆及直杆,第一横杆连接于两弧形杆的中部,直杆垂设于两弧形杆连接位与第一横杆之间;牵引杆设于支撑架的前端,并位于直杆的延长线上,牵引杆的前端设穿戴式牵引件。本发明采用逐渐上扬的弧形杆,更符合人体工学,牵引者在牵引时更为省力;支撑架所限定出的弧形面能够在牵引者下肢与拖车之间形成一个供牵引者抬腿的三角空间,不仅可实现站姿牵引,还可实现卧姿牵引以满足狭窄区域和特殊环境的使用,功能性更强。
