Description

Technical Field

[0001] The utility model relates to a carton, and more specifically, to a high-strength carton. Background Art

[0002] Cartons are a widely used packaging product. For more than half a century, 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 warehousing and transportation, they also play a role in beautifying and promoting goods. Moreover, cartons are green environmental protection products, which are beneficial to environmental protection and loading and unloading transportation.

[0003] At present, in the process of transportation and storage of existing cartons, the edges and faces of the cartons are extremely vulnerable to damage, which affects the strength and hardness of the cartons themselves, making them unable to better withstand the pressure during transportation and storage and causing damage to the items inside the cartons.

[0004] For the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0005] In view of the problems in the related art, the utility model proposes a high-strength carton to overcome the above technical problems existing in the related art.

[0006] To this end, the specific technical solution adopted by the utility model is as follows:

[0007] A high-strength carton includes a carton body. A paper cavity is provided inside the carton body. Partition grooves are symmetrically provided on both sides of the inner surface of the paper cavity. Partition plates are slidably connected in the partition grooves. A vertical plate is slidably connected between the partition plates. Reinforcing side plates are fixedly connected to the four circumferences of the outer surface of the carton body. An X-shaped stabilizing strip is fixedly installed between the reinforcing side plates. A reinforcing bottom frame is fixedly connected to the bottom end of the carton body. The carton body is composed of a cardboard body. The cardboard body includes an outer layer, a reinforcing layer, and an inner layer. The reinforcing layer is fixedly installed between the outer layer and the inner layer. The reinforcing layer includes an outer corrugated layer and an inner corrugated layer. Reinforcing longitudinal bars are equidistantly arranged between the outer corrugated layer and the inner corrugated layer. Reinforcing cross bars are fixedly connected equidistantly between the reinforcing longitudinal bars. Reinforcing vertical bars are fixedly installed equidistantly at the top and bottom ends of the reinforcing longitudinal bars. The top and bottom ends of the reinforcing vertical bars are respectively fixedly connected to the outer corrugated layer and the inner corrugated layer.

[0008] Furthermore, in order to increase the moisture-proof performance of the carton, a moisture-proof layer is provided between the outer layer and the reinforcing layer. The moisture-proof layer is fixedly connected to the outer layer and the outer corrugated layer respectively through an adhesive.

[0009] Furthermore, in order to protect the surface of the cardboard box, an outer protective layer is fixedly connected to the outer surface of the outer layer.

[0010] Furthermore, in order to facilitate the storage of small-sized items, vertical grooves are equidistantly formed on one side of the partition board, and the vertical grooves are slidably connected to the vertical plates.

[0011] Furthermore, in order to avoid external force collision and strengthen the side plates, anti-collision strips are fixedly connected to the outer surface of the strengthening side plates.

[0012] Furthermore, in order to facilitate the handling of the cardboard box, square openings are formed at both ends of the outer surface of the cardboard box body, and a grasping plate is fixedly installed at the top end of the square openings.

[0013] Furthermore, in order to make the cardboard box stable on the ground, support legs are symmetrically provided at the bottom end of the strengthening bottom frame.

[0014] Furthermore, in order to increase the friction between the cardboard box and the ground, anti-slip foot pads are fixedly connected to the bottom ends of the support legs.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. By providing strengthening side plates and X-shaped stabilizing strips outside the cardboard box body, the strength of the outer surface of the cardboard box body is further increased. The cardboard body on the cardboard box body adopts a multi-layer structure, which further enhances the overall strength of the cardboard box body. And outer corrugated layers, inner corrugated layers, strengthening cross bars, strengthening longitudinal bars and strengthening vertical bars are respectively arranged in the cardboard body, which protects the strength of the cardboard box surface to a certain extent, effectively prevents the cardboard box from deforming and cracking, and further improves the compressive capacity and impact resistance of the cardboard box.

[0017] 2. Through the mutual cooperation between the partition board, partition grooves, vertical plates and vertical grooves, the paper cavity is divided into multiple chambers, which facilitates the classified placement of items. At the same time, it avoids the mutual collision between items during handling or transportation, resulting in damage to the items. BRIEF DESCRIPTION OF THE DRAWINGS
