The invention provides a manual control constant brake universal wheel, and relates to the technical field of universal wheels. A manual control constant brake universal wheel comprises a mounting box, a wheel carrier and a wheel rotationally arranged on the wheel carrier. The mounting box is rotationally provided with a rotating assembly; the wheel frame is arranged on the rotating assembly; the rotating assembly is slidably provided with an installation rod in the vertical direction, and the installation rod is provided with a brake shoe matched with a wheel. The mounting box is provided with a driving assembly used for driving the mounting rod to slide in the vertical direction. By the adoption of the trolley, automatic braking is achieved when the trolley is not used, operation is convenient, speed reduction can be achieved through braking when the trolley is pushed to go downhill, a worker does not need to pull a handle of the trolley forcefully to enable the trolley to slide downwards without acceleration, and the labor intensity of the worker is reduced.
本发明提出了一种手动控制常刹万向轮,涉及万向轮技术领域。一种手动控制常刹万向轮,包括安装箱、轮架以及转动设于轮架的车轮;安装箱转动设有旋转组件,轮架设于旋转组件;旋转组件沿竖直方向滑动设有安装杆,安装杆设有与车轮配合的刹车蹄片;安装箱设有用于驱动安装杆沿竖直方向滑动的驱动组件。采用本发明,在不使用手推车时自动刹车,操作方便,而且推动手推车下坡的过程中可以通过刹车进行减速,不需要工作人员用力拉着手推车的把手让手推车不加速往下滑动,降低了工作人员的劳动强度。
