Description

Technical Field

[0001] The utility model relates to the technical field of hardware fitting packaging, in particular to a packaging box with a buffer structure. Background Art

[0002] A grinding sheet is a fitting for grinding workpieces. Before being sold, it needs to be packaged to avoid damage. The existing patent (publication number: CN221050442U) discloses a grinding sheet packaging box with a buffer protection structure. By arranging a plurality of supporting blocks in the second inner box body, while achieving a buffer support effect on the articles, the moisture absorption cloth bag filled in the lower part of the groove is used to absorb the internal water vapor, achieving a good moisture-proof effect. However, in actual application, the grinding sheet is placed between adjacent supporting blocks. In order to facilitate placing the supporting blocks therein, generally, there is a gap between the inner wall of the second inner box body and the grinding sheet, which causes the grinding sheet to easily move back and forth between adjacent supporting blocks, making the grinding sheet frequently collide with the inner wall of the second inner box body, which is not conducive to actual application. For this reason, we propose a packaging box with a buffer structure. Content of the Utility Model

[0003] In order to solve the above problems, the utility model provides a packaging box with a buffer structure.
