The invention relates to a caster wheel capable of braking. A braking mechanism of the caster wheel is positioned inside a wheel body component and comprises a controller provided with a signal receiving unit, a locking device controllably connected to the controller, and a rotary damper. The rotary damper is provided with a first part with a limiting structure and a second part fixed on the wheel body component, wherein the first part is separated from or matched with the locking device through the limiting structure to form a rotatable free state or an irrotatable locking state, and the first part is in opposite rotating fit with the second part through a damping element. The design of the rotary damper is used in the caster wheel; after exceeding the specified area, a trolley also can be slowly pushed under the action of the rotary damper instead of being suddenly and completely locked, thereby the risk on users can be avoided and the damage on the wheel body by forcing to push the trolley after the caster wheel is locked can be prevented.
Description
technical field [0001] The invention relates to a caster, in particular to a caster with a braking mechanism. Background technique [0002] Supermarket shopping has increasingly become an indispensable consumption behavior for modern people in today's society. As a convenient delivery tool for supermarket shopping, supermarket shopping carts play an important role in supermarket shopping. After the supermarket shopping cart is used to load the goods, most of the domestic supermarket shopping carts are recycled by the supermarket staff at present, which wastes human resources. At the same time, the labor cost is getting higher and higher, which is not conducive to the cost control of the supermarket. The theft of supermarket shopping carts also happens from time to time. Since each shopping cart is quite expensive, the loss of the shopping cart causes great economic losses to the merchant. [0003] Based on the theft of supermarket shopping carts and saving labor costs, ant...
