They are rigid or semi-rigid materials with high strength and are not easy to deform. The packaging boxes have high overall strength, strong deformation resistance, and large packaging volume. They are suitable for transportation packaging and outer packaging. They have a wide packaging range and are mainly used for solid grocery packaging.

[0003] However, existing anti-collision packaging boxes are generally filled with foam and other structures. Although such fillings can reduce shock, their anti-collision effect is limited, which may cause items to be damaged by collisions, reducing the protective effect. In addition, the box cover is generally fixed with rivets, which makes it difficult to install and disassemble, and inconvenient to store and remove samples, and the packaging box cannot be reused, reducing its use efficiency. In addition, traditional packaging boxes are not flexible enough in the selection of transportation status and placement status, resulting in the flexibility of the packaging box failing to meet the requirements.

[0014] In view of this, compared with the prior art, the beneficial effects of the present invention are: (I) In the present application, when storing packaged items in the packaging box storage chamber, the external hand wheel is turned to rotate the horizontal adjustment screw, and the linear slider moves in the linear slide, and drives the three-sided anti-collision rod to move, so that the two three-sided anti-collision rods move away from each other and move away from the top of the packaging box cover. Then the three-sided anti-collision rod and the cover pressing mechanism release the obstruction and pressure on the packaging box cover, so as to open the packaging box cover, and then the items can be packaged and stored. The classification partition separates the inner cavity of the packaging box storage chamber and supports and limits the packaging box cover to prevent the packaging box cover from moving into the packaging box storage chamber and squeezing the stored items.

[0015] (ii) In the present application, after storage is completed, the external hand wheel is rotated again to make the two three-sided anti-collision bars approach each other, and the cover pressing mechanism is moved again to the top of the packaging box cover. The three-sided anti-collision bars block the packaging box cover to prevent it from being opened upwards, and under the elastic force of the return spring (the return spring is in a compressed state), the circular cover pressing plate tends to move downward and presses on the top of the packaging box cover so that the packaging box cover seals the packaging box storage chamber, thereby realizing rapid packaging of items. Under the action of the rectangular protective bottom frame, the single-sided anti-collision bar, the connecting cross bar and the three-sided anti-collision bar and other structures, the packaging box has a better anti-collision effect. The three-sided anti-collision bar adopts a movable installation method and cooperates with the opening method of the packaging box cover, so that the use of the packaging box is more flexible and reusable.

[0016] (III) In the present application, the U-shaped lifting handle in the lifting mechanism can be used for lifting by hand, and the U-shaped lifting handle can be rotated to a "horizontal state" or a "vertical state". In the "vertical state", it is convenient to twist up the packaging box. After the three-sided anti-collision rods are moved away from the top of the packaging box cover, in the "horizontal state", they are prevented from hindering the opening of the packaging box cover. At this time, the pressing mechanism will not affect the opening action of the packaging box cover. The layout is reasonable and beautiful.

[0017] (IV) In the present application, during the process of storing items, the moving wheels are located in the storage chamber, and each placement support leg supports the packaging box to ensure the stability of the packaging box storage chamber so that the items can be stored in the packaging box. After the packaging is completed, the second handle can be turned to rotate the Z-axis adjustment screw, and the lifting slide bar drives the linkage frame to move downward, so that the movable block drives the moving wheel to move downward until it moves out of the storage chamber. At this time, the setting of the moving wheel facilitates the transportation and transfer of the packaging box, so that the placement state and the moving state of the packaging box can be flexibly switched.
