Description

Technical Field

[0001] The utility model belongs to the technical field of turnover boxes, and in particular relates to a turnover box base which is easy to move. Background Art

[0002] The turnover box base is an auxiliary tool for placing and moving turnover boxes, mainly used in logistics, warehouse management and other fields. The base is equipped with rollers, which can easily move the turnover boxes containing goods between different locations, reducing the intensity of manual handling. Since the rollers of the turnover box base in the related art cannot be stored, the rollers will occupy additional space, affecting the convenience of storage and sorting and the effective use of space. Since the rollers are usually fixed at the four corners of the base, they may be subjected to greater forces when supporting the turnover box, especially when the turnover box is loaded with heavy or unbalanced goods. The traditional roller structure cannot provide sufficient stability, which can easily cause the overall shaking or instability of the base, affecting the safe use of the turnover box. The slide rails of the turnover box base are usually responsible for guiding the turnover box to be correctly placed on the base. Since the base slide rails in the related art are prone to deformation, the stable placement and sliding effect of the turnover box are affected. The deformed slide rails may also increase the difficulty and safety risks when loading and unloading items. Summary of the invention
