A freight trolley convenient to climb stairs comprises a trolley frame, wheels installed below the rear side of the trolley frame and a supporting frame arranged on the rear side of the trolley frame in a protruding mode and located on the inner sides of the two wheels. The rear surface of the supporting frame is a supporting face used for assisting the wheels to climb stairs, the supporting face is arranged up and down, and the distance between the supporting face and the frame in the front-back direction is gradually increased or equal from top to bottom. The distance between the lower end of the supporting face and the frame in the front-back direction is smaller than the distance between the rear surface of the wheel and the frame in the front-back direction. In the process of not influencing normal rolling of the wheels, the outer edges of the wheels and the supporting faces are smoothly connected in the stair climbing process, the sliding process between the supporting faces and the intersecting lines is smoothly transited to the rolling process between the wheels and the intersecting lines, and the trolley is more labor-saving and convenient in the stair climbing process.

    一种便于上楼梯的运货手推车,包括车架、安装于车架后侧下方的车轮以及凸设于车架后侧且位于两车轮内侧的支撑架;支撑架的后表面为用于辅助车轮爬楼梯的支撑面,支撑面上下设置,且支撑面与车架在前后方向的距离由上至下逐渐增大或相等;支撑面下端距离地面的高度小于车轮上表面距离地面的高度,且支撑面下端与车架在前后方向的距离小于车轮后表面与车架在前后方向的距离。在不影响车轮正常滚动的过程中,使车轮的外缘与支撑面在上楼梯的过程中流畅的衔接,将支撑面与相交线之间的滑动过程流畅地过渡到车轮与相交线之间的滚动过程,本案中的手推车在上楼梯过程更加省力方便。
