AI Technical Summary
When existing trolley boxes stand for a long time, users are prone to fatigue, and sitting directly on the box may cause damage to the box or damage to internal items.
A bag with expansion function was designed, including sewing a canvas bag on the rear side wall of the trolley box body. The two side walls of the canvas bag are fixedly connected to the supporting legs of the expansion structure, and the cross bar of the expansion structure and the canvas cover are passed through the hanging hole. It quickly overlaps with the limiting column to form a soft plane that can support the body.
In scenarios such as security check queues, users are provided with quick sitting rest options, which improves the convenience and comfort of use. At the same time, after the expansion structure is pulled out, additional expansion space is provided and load-bearing capacity is improved.
