Description

Technical Field

[0001] This utility model relates to the field of packaging and storage technology, and in particular to foldable portable storage cardboard boxes. Background Technology

[0002] Traditional cardboard boxes are widely used in daily life and logistics. However, they have several significant limitations. First, in terms of space utilization, their fixed structure prevents them from being effectively folded when not in use, occupying a large amount of storage and transportation space and severely restricting efficient space utilization. This is undoubtedly a major problem, especially for logistics companies and families with limited space.

[0003] A search revealed Chinese Patent Publication No. CN211732172U, which discloses a foldable storage cardboard box. The box includes a main body with a hollow interior. First pivot blocks are fixedly connected to both the front and rear ends of the top of the main body. Upper panels are movably connected to the front and rear ends of the top of the main body via the first pivot blocks. Second pivot blocks are fixedly connected to both sides of the top of the main body. This foldable storage cardboard box, through the design of limiting blocks, a covering cloth, and fixing rods, allows the top of the main body to be covered when large items are not needed. The design of the first pivot blocks, second pivot blocks, upper panels, and side panels expands the storage volume of the main body, facilitating the storage of larger items. The design of the first limiting frame, connecting block, second limiting frame, and top block limits the upper and side panels, preventing them from tilting. It is simple to operate, portable, and meets the user's needs.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the multi-axis structure of the device requires multiple limiting components, making the assembly process cumbersome and user operation inconvenient; insufficient support stability: the expanded box is prone to structural imbalance due to side panel tilting, affecting load-bearing capacity; limited space utilization: the U-shaped divider design is shallow and lacks layered reinforcement structure, making it difficult to meet the needs of refined storage; portability needs optimization: the volume reduction after folding is limited, and the handle design does not achieve modular storage, occupying additional space.
