[0002] As a powerful assistant in the field of industry and logistics, trolleys are widely praised for their flexibility and convenience, especially thanks to the caster design, which significantly enhances their mobility under variable ground conditions. However, although this design innovation improves work efficiency, it also buries safety risks, especially the potential risks to the safety of users' feet, which has not been fully addressed in existing designs.
[0003] Traditional cart designs focus on load-bearing, stability, and mobility, but ignore safety protection measures around casters. In high-intensity work scenarios, such as warehouses, supermarkets, medical facilities, and factories, space constraints and high traffic coexist, requiring cart operations to be both quick and precise. During use, the operator's feet are prone to slip under the exposed casters when the cart starts or turns sharply, which can cause the shoes to deform at the least, or cause serious injuries such as contusion, extrusion, or even fracture of the feet. This poses a direct threat to employee health, reduces work efficiency, and may bring high compensation costs and operational risks to employers. Therefore, how to strengthen the safety design of the caster area while maintaining the efficient operation of the cart has become an urgent problem to be solved. Utility Model Content
