[0002] The universal wheel is a special wheel installed on a trolley. It can rotate freely in multiple directions, making the trolley more flexible and convenient when moving. The design principle of the universal wheel mainly relies on its internal bearing structure and steering mechanism, which enables the wheel to easily change direction without the user having to laboriously adjust the overall direction of the trolley. The trolley with universal wheels is widely used in various occasions, such as warehouses, supermarkets, hospitals, factories, etc., for transporting goods, equipment or other heavy objects; the existing universal wheels basically meet daily needs, but still have certain defects. The existing trolleys need to use tools or other materials to block the universal wheels when stopping on a slope with a certain inclination angle, which is inconvenient to use. When the ground is uneven, the trolley may tilt after stopping, causing the materials and goods therein to spill, which is easy to waste materials; the existing universal wheels may stick to dirt under poor working conditions, which is easy to affect the use of the trolley, so it is necessary to design a universal wheel with a top column structure.
