The invention provides a foldable wheel for a trolley. According to the foldable wheel for the trolley, by pressing an elastic pressing plate, a front baffle on the front side face of the elastic pressing plate is not parallel to the end face of a rotary fixing block any more, the rotary fixing block can rotate with a rotary cylindrical pin as a shaft, and meanwhile tooth-shaped ladder teeth on a semicircular lug plate are in meshing transmission with meshing tooth grooves in a gear disc; the gear disc drives the octagonal cylinder and the wheel set to rotate around the fixing block direction pin, the cylindrical sliding pin enters the stop groove of the rotary fixing block, the stop cylindrical pin is locked in the C-shaped spring steel, the rotary fixing block is fixed, and the wheel set is folded. The wheel folding process is simple and can be continuously completed at a time. According to the foldable wheel, the packaging size can be reduced, the transportation cost and the storage space are saved, goods transportation is facilitated, the wheel can be kept in a folded state after being folded due to the arrangement of the locking mechanism, and stability is improved.

    本发明提出一种手推车用的可折叠车轮,通过按压弹压板,使弹压板前侧面上的前档板与旋转固定块的端面不再平行,旋转固定块能够以回转圆柱销为轴转动,同时半圆耳板上的牙型梯齿与齿轮盘上的啮齿槽啮合传动,使得齿轮盘带动八边形柱体以及车轮组绕固定块方向销转动,圆柱体滑销进入旋转固定块的休止槽,停止圆柱销被锁止在C型弹簧钢内,旋转固定块被固定,车轮组完成折叠。车轮折叠过程简单、能一次连续完成。可折叠车轮不仅可减少包装体积、节省运输成本和储存空间、方便货物运输,锁止机构的设置使得车轮折叠后可保持折叠状态,提高稳定性。
