Description

Technical Field

[0001] The utility model belongs to the field of packaging boxes, and in particular relates to a material packaging box with a buffering function. Background Art

[0002] A packaging box is an outer carrier used to hold items to be transported. It has certain protective functions and is convenient for protecting and distinguishing items in transport.

[0003] A Chinese patent with announcement number CN220484139U discloses a multi-compartment buffer packaging box for electronic products, including a box body, a top cover on the top of the box body, a number of buffer bottom plates inside the box body, hemispherical rubber pads on both sides of the buffer bottom plates, the hemispherical rubber pads and the buffer bottom plates are connected to the buffer bottom plates by glue, a supporting plate is provided above the buffer bottom plates, a limit block is fixedly provided under the supporting plate, one side of the limit block is concave, connecting columns are provided at the four corners of the supporting plate, fixing rings are provided at both ends of the connecting columns, a card plate is provided on the side of the supporting plate, a slide groove is provided on the card plate, a limit slider is provided in the slide groove, a rubber block is provided on one side of the limit slider, and a protective frame is provided above the supporting plate.

[0004] However, when the multi-compartment buffer packaging box for electronic products disclosed in the application is used, it is not easy to separate the outer pallet from the box body because the outer pallet is connected to the box body by glue. After long-term use, the box body may become unusable due to bumps, moisture, damage or stains, making it inconvenient to replace the box body alone. Replacing the box body together with the outer pallet will easily increase the replacement cost. Utility Model Content
