Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard box technology, and in particular relates to an abrasion-resistant corrugated cardboard box. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. This includes calcium-plastic corrugated boxes. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and easy processing, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are environmentally friendly products, benefiting both environmental protection and ease of loading and unloading.

[0003] Traditional corrugated cardboard boxes, when used for packaging items after bending, cannot protect the folded corners on the sides of the box. This makes the folded corners of the box prone to bumps and wear during transportation, thus reducing the service life of the corrugated cardboard box. Therefore, an abrasion-resistant corrugated cardboard box is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a wear-resistant corrugated cardboard box to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a wear-resistant corrugated cardboard box, comprising a box body, a bottom plate, and a baffle. Two sets of connecting plates are provided at each of the four corners of the upper surface of the bottom plate. Each set of connecting plates has a slot on one side and a threaded hole on the other side. An elastic sheet is provided between the two sets of connecting plates, and rubber pads are provided on both opposite surfaces of the elastic sheet. An adhesive layer is provided on the upper surface of the bottom plate. Symmetrical insertion holes are provided on one side of the baffle, and bolts are threaded into the threaded holes. A cavity is provided inside the box body. Several hemispheres (first type) are provided on the left inner wall of the cavity, and several hemispheres (second type) are provided on the right inner wall of the cavity. The diameter of the second hemisphere is smaller than that of the first hemisphere. Several slots are provided on the inner wall of the box body, and partitions are provided within the slots. The bottom surface of the box body is fixedly connected to the upper surface of the bottom plate via the adhesive layer. One side of each connecting plate is attached to the side of the box body.

[0007] Furthermore, the shape and size of the baffle are adapted to the slot, the shape and size of the threaded hole are adapted to the insertion hole, the position of the threaded hole and the insertion hole are adapted, the shape and size of the bolt are adapted to the insertion hole, one end of the bolt is set in the insertion hole, the bolt is threadedly connected to the threaded hole, and both hemisphere one and hemisphere two are aligned and staggered, and both hemisphere one and hemisphere two are hemispherical hollow protrusion structures.

[0008] This utility model has the following beneficial effects:

[0009] This utility model involves placing the box body on the surface of the base plate and connecting and fixing it with an adhesive layer. Then, one side of the connecting plate is attached to the side of the box body, and the baffle is inserted into the slot. The insertion hole on the surface of the baffle coincides with the threaded hole. The bolt is screwed into the threaded hole, and one end of the bolt is inserted into the insertion hole for fixed installation. The elastic sheet and rubber pad between the two sets of connecting plates provide protection, making it less likely for the corner of the carton to be bumped and worn during transportation, thereby improving the service life of the corrugated carton. The cavity opened in the box body, with hemispheres one and two on the inner wall of the cavity, can form an effective buffer layer when subjected to pressure, reducing the impact of pressure on the inside of the carton. At the same time, the partitions in the box body can be freely adjusted according to the usage situation. The partitions can slide along the slots opened in the inner wall of the box body, thereby facilitating the division of the internal space of the carton and improving the loading capacity and practicality of the carton.

[0010] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
