AI Technical Summary
Traditional luggage lacks locking mechanisms, making it difficult for the casters to park smoothly and prone to damage.
A luggage structure was designed that uses a rotating cap to drive a bevel gear system, causing the casters to lock into the control slot. The locking rod and the locking slot work together to prevent the casters from rotating, thus achieving control over the retraction and extension of the casters.
It achieves stable parking of luggage and protects the casters, preventing the casters from being exposed and damaged, and ensuring the normal movement and use of luggage.
