The bottom of the traditional paper box is usually formed by mutually clamping or bonding bottom paperboards extending below the side paperboards, and the bottom paperboards are easy to disintegrate under the action of heavy objects, so that the bottom paperboards cannot bear the heavy objects. For the present invention, after the large heavy product is placed in the carton, the product is crimped to the first receiving plate 23 on the base 1. Because the structure of the carton is limited, the handle structure is usually formed on the side wall of the carton, and then the carton is carried through the handle structure, in this embodiment, the handle structure is preferably formed on the first side plate 21, when the carton is suspended by lifting the first side plate 21, the first side plate 21 is directly stressed, and the first receiving plate 23 has a tendency of sliding along the horizontal direction under the action of the first side plate 21, so that the key of ensuring that the carton can bear products is to limit the sliding of the first receiving plate 23 along the horizontal direction. In the invention, the first bearing plates 23 on two sides are tightly pressed on the base 1 by the product, static friction force is generated between the first bearing plates 23 and the base 1, and the friction force is opposite to the pulling force of the first side plate 21 pulling the first bearing plates 23, so that the first bearing plates 23 can be prevented from sliding along the horizontal direction, the maximum static friction force is in direct proportion to the dead weight of the product, and the greater the weight of the product is, the greater the maximum static friction force is, so that the product can adapt to products with different weights. On the other hand, the first receiving plate 23 is fixedly connected with the base 1, and the base 1 can also serve the purpose of limiting the first receiving plate 23 to slide along the horizontal direction.

Referring to fig. 5, there is shown an exploded view of a second embodiment of the present invention with one side of the second side panel 22 hidden. As shown in the figure, this embodiment is different from the first embodiment in that the second cover 3 and the fourth receiving plate 4 are further included.

The fourth receiving plate 4 is located above the first receiving plate 23 and covers the first receiving plates 23 on both sides. When the novel product pressing device is used, a product is placed on the fourth bearing plate 4, on one hand, the fourth bearing plate 4 can disperse the gravity of the product, so that the first bearing plate 23 is uniformly pressed on the base 1; on the other hand, friction force can be generated between the fourth bearing plate 4 and the first bearing plate 23, and the strength of the carton is increased at the other part.

Referring to fig. 6 and 7, fig. 6 is an exploded view of a third embodiment of the present invention, fig. 7 is an enlarged view of a connection portion between the first cover and the third side plate, and fig. 6 is a hidden view of the second side plate 22. As shown in the figure, the difference between the present embodiment and the second embodiment is that the present embodiment further includes a first cover 5, a third side plate 6, a second receiving plate 7, and a third receiving plate 8.

The two third side plates 6 are respectively positioned on the left side and the right side of the base 1, and the third side plates 6 are attached to the inner surface of the first side plate 21 positioned on the same side and are fixedly connected with the first side plate. One embodiment of the fixed connection between the third side plate 6 and the first side plate 21 is that handle holes (not shown) are correspondingly formed in the third side plate 6 and the first side plate 2, and then handles (not shown) are respectively fixed in the handle holes.

The bottom of the third side plate 6 is provided with a third bearing plate 8, and the third bearing plate 8 is positioned above the first bearing plate 23 and is attached to the first bearing plate 23. The fourth receiving plate 4 is located above the third receiving plate 8 and covers the third receiving plates 8 on both sides.

The third side plate 6 and the first side plate 21 can support each other on one hand, so that overall strength is increased, stacking of the cartons in the vertical direction can be achieved on the other hand, referring to fig. 7 specifically, the top of the third side plate 6 is lower than the top of the first side plate 21 on the same side, the first box cover 5 is inserted into the inner cavity of the box wall 2 and abuts against the top of the third side plate 6, and therefore when a heavy object (such as other cartons) is stacked on the cartons, the gravity of the heavy object is transferred onto the third side plate 6 through the first box cover 5, and due to the supporting effect of the first side plate 21 on the third side plate 6, the third side plate 6 can bear larger vertical acting force, and therefore strength requirements of stacking of the cartons are met.

Furthermore, above the first cover 5, there is a second receiving plate 7, which second receiving plate 7 can distribute the weight of the stacked objects above.

The threaded fastener for realizing separable connection can be a nut and a screw, in particular, the nut is fixed on the paper board of the paper box in a clamping manner and the like, and the screw penetrates through a through hole on the paper board to be connected and then is screwed into the nut, so that separable connection between the paper boards can be realized.
