Description

Technical Field

[0001] The utility model belongs to the technical field of carton bodies, and particularly relates to a high-strength corrugated carton. Background Art

[0002] At present, corrugated cardboard is made into corrugated cartons through die-cutting, indentation, stapling or gluing. Corrugated cartons are the most widely used packaging products, and their usage has always been the first among various packaging products. For more than half a century, corrugated cartons have gradually replaced transportation packaging containers such as wooden boxes with their superior performance and good processing performance, becoming the main force in transportation packaging. In addition to protecting goods, facilitating storage and transportation, corrugated cartons are green environmental protection products, which are beneficial to environmental protection and loading and unloading transportation. However, the strength of general corrugated cartons is still relatively poor. When subjected to relatively large pressure, they will undergo serious deformation, thereby damaging the items inside the box and making the box body unable to be used again. In addition, after the box body is deformed and damaged by external forces, it is easy to affect the stability of the stacked goods, causing damage to the goods and bringing unnecessary economic losses. Therefore, the stability of corrugated cartons is of crucial importance. In view of this, this solution was developed. Content of the Utility Model

[0003] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a high-strength corrugated carton with relatively high strength.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a high-strength corrugated carton, including a carton body. The carton body is composed of a first cardboard layer, a metal mesh layer and a second cardboard layer from top to bottom. The carton body includes a bottom plate, a first side plate, a second side plate, a third side plate and a fourth side plate. The first side plate, the second side plate, the third side plate and the fourth side plate are respectively connected to the four sides of the bottom plate. First metal sheets are formed on both sides of the first side plate and the third side plate. Second metal sheets are formed on both sides of the second side plate and the fourth side plate. The first metal sheets are folded inwards, and the second metal sheets are folded outwards towards the adjacent outer sides of the first side plate or the third side plate. The corresponding first metal sheets and second metal sheets are fixedly connected through connecting pieces;

[0005] A plurality of first connection holes are formed on the first metal sheets and the second metal sheets. A plurality of second connection holes are formed on both sides of the first side plate and the second side plate. The first connection holes on the first metal sheets and the second metal sheets correspond to the second connection holes adjacent to the first side plate or the third side plate;

[0006] The connecting member includes a buckle body and a fastener. The buckle has a buckle hole which is divided into a locking part and a connecting part. The diameter of the locking part is larger than that of the connecting part. Two deformation columns are formed on the lower surface of the fastener, and the two deformation columns are arranged at intervals. A clamping head extending outward is formed at the end of the deformation column. The clamping head passes through the first connecting hole and the second connecting hole, and the clamping head is adapted to the locking part.

[0007] Further, the metal mesh layer includes a metal frame, horizontal wires and vertical wires. The horizontal wires and the vertical wires are arranged alternately inside the metal frame, and the metal frame, the horizontal wires and the vertical wires are fixedly connected to each other.

[0008] Further, first metal sheets are fixedly connected to both sides of the metal frame on both sides of the first side plate and the third side plate, second metal sheets are fixedly connected to both sides of the metal frame on both sides of the second side plate and the fourth side plate, and the metal mesh layers inside the bottom plate, the first side plate, the second side plate, the third side plate and the fourth side plate are fixedly connected to each other.

[0009] Further, the fastener is located inside the first side plate or the third side plate, and the inner surface of the fastener facing inward is an arc surface.

[0010] Further, the connecting member includes a screw and a nut. The head of the screw is located inside the first side plate or the third side plate. The screw passes through the first connecting hole and the second connecting hole, and the screw and the nut are adapted to each other.

[0011] Further, an upper cover plate is formed on the outer surfaces of the first side plate, the second side plate, the third side plate and the fourth side plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the bottom plate, the first side plate, the second side plate, the third side plate and the fourth side plate of the carton body are all composed of a first cardboard layer, a metal mesh layer and a second cardboard layer. By sandwiching and bonding the metal mesh layer between the first cardboard layer and the second cardboard layer, the strength of the whole carton body is improved. During the process of carrying objects on the carton board body, better bearing capacity can be obtained through the support of the metal mesh layer, and it can withstand lateral tension better; first metal sheets and second metal sheets are also formed on both sides of the first side plate, the second side plate, the third side plate and the fourth side plate.
