Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a pressure-resistant composite cardboard packaging box. Background Technology

[0002] Corrugated cardboard is typically made of a corrugated core paper (corrugated paper) and two layers of flat linerboard (face paper). While lightweight, this structure is very strong, providing excellent cushioning and support. Corrugated boxes made from corrugated cardboard are widely used in industries requiring high pressure resistance, long-distance transportation, or special storage environments, such as the express delivery and logistics industry. For example, while corrugated boxes from Dasen Paper Industry can protect the contents, when the top of the box is subjected to pressure, the top of the item is directly subjected to the pressure, leading to damage.

A first upper plate is fixedly connected to the top of each side plate, and a second upper plate is fixedly connected to the top of each bottom plate. A bottom plastic plate is placed on the top of the bottom plastic plate, and several plastic supports are placed on the top of the several plastic supports. A top plastic plate is placed on the top of each of the plastic supports. Insertion holes are provided on the surfaces of the top and bottom plastic plates, and the top and bottom ends of the plastic supports are inserted into the corresponding insertion holes. The end plates, bottom plates, side plates, first upper plates, and second upper plates are all made of pressure-resistant composite corrugated cardboard.

[0005] Preferably, the top of the top plastic plate has a buckle groove, and a buckle plate is fixedly connected to one side of the inner cavity of the buckle groove.

[0006] Preferably, a lower protective sleeve is adhered to the outer side of each of the four corners of the base plate.

[0007] Preferably, an upper protective sleeve is adhered to the outer side of the angle between the first upper plate and the second upper plate.

[0008] Preferably, the top of the upper protective sleeve is provided with a buckle hole, and a buckle block is fixedly connected to one side of the inner cavity of the buckle hole.
