AI Technical Summary
Existing strollers with simple swivel wheels are flexible in steering under heavy loads, but their direction is unstable and difficult to control when there is no load or a light load. On the other hand, simple fixed wheels are not flexible in directional control under heavy loads and the wheels wear out quickly.
Design a swivel wheel with a directional structure. By opening directional slots on the wheel frame and combining a directional mechanism and a front top assembly, the swivel wheel can be directionally locked in the slots under heavy loads and allowed to rotate inertially under light loads. Combined with a rotating bearing, the swivel wheel's flexibility and stability are ensured.
It achieves stable and flexible control under both light and heavy loads, improves the ease of use of the trolley, and reduces wear on the casters.
