In actual use, the buffer plates 4 can effectively absorb external impact force, reduce the vibration and collision of the items inside the box body 3, thereby reducing the risk of damage to the items during transportation and storage, and protecting the safety of the items. The combination of the insertion frame 302 and the buffer plates 4 can increase the overall strength of the box body 3, making it more durable, thereby improving the overall buffering effect. At the same time, the mutual engagement of the insertion frame 302 and the buffer plates 4 makes the assembly and disassembly of the buffer plates 4 more convenient and quick, thereby facilitating replacement and improving production efficiency.

In the present invention, a layer of honeycomb cardboard 303 is provided in the side wall interlayer of the box body 3. The honeycomb structure of the honeycomb cardboard 303 itself enhances the strength and rigidity of the entire box body 3, thereby enhancing the overall performance of the paper box body 3. In actual use, the honeycomb structure of the honeycomb cardboard 303 gives it a high compressive strength. This structure can evenly distribute external force to the entire board surface, thereby reducing local pressure and further improving the overall compressive resistance of the box body 3. The material of the honeycomb cardboard 303 is relatively light, but has good rigidity, so that it can maintain a good shape when squeezed and is not easily deformed, thereby ensuring that the shape of the box body 3 itself is fixed. At the same time, the honeycomb cardboard 303 also has good buffering performance. When impacted by external force, it can absorb energy through its own elastic deformation, reducing the damage to the box body 3 caused by the impact force.

After completing the engagement between all the partitions 6 and the slots 5, the multiple partitions 6 form a continuous triangular connection, and at the same time, the entire box body 3 is divided into multiple spaces inside, which is convenient for placing and organizing items. At this time, the entire top cover 1 can be covered on the top of the box body 3. During this period, the card strip 101 provided at the bottom of the top cover 1 will be vertically inserted into the card slot 301 opened at the top of the box body 3 to form a mutual engagement, and at the same time, the card strip 101 provided at the bottom end of the card strip 101 and the bottom wall of the card slot 301 will be engaged with each other. The magnetic sheets will be tightly attracted together at the moment of contact, thereby completing the closing between the top cover 1 and the box body 3. The operator will perform subsequent handling and transportation operations on the entire box body 3. During this period, the bottom of the entire box body 3 is repeatedly placed, and the cavity 7 provided in the interlayer of the bottom wall of the box body 3 will directly transmit the vibration impact it receives to the buffer spring member 701 provided therein, and absorb and release it slowly, thereby reducing the protection of the box body 3 and the items placed therein.
