Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a packaging box with a quick-assembly pulley structure. Background Technology

[0002] Packaging boxes are containers used for packaging, transporting, and storing goods, and are widely used in logistics, warehousing, retail, and other fields. Depending on different needs and application scenarios, packaging boxes come in various types and materials.

[0003] Most current packaging boxes are fixed-form. When not loaded with goods, fixed-form packaging boxes often occupy a large space, which leads to a waste of space resources during warehousing and transportation. In addition, traditional packaging box designs usually lack flexibility, cannot be folded, and do not have wheels at the bottom, making it inconvenient to handle and move. This limits their application in various scenarios, resulting in limitations on their reusability and space efficiency, which increases the overall logistics costs. Utility Model Content
