Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper, and in particular to a high-quantity and high-strength corrugated paper box. Background Art

[0002] The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled and regenerated. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used. Although corrugated paper is easy to use and recyclable, the existing corrugated paper can only have strong supporting force in one direction, and it will become easy to bend when subjected to side force. After the corrugated box is bent on the side, the seals at the upper and lower ends will become unstable. Therefore, we need to propose a high-strength corrugated box.

[0003] After searching, the Chinese patent publication number is CN219948874U, which discloses a high-strength corrugated paper box. In this patent, the outer box body, the inner box body and the reinforcement frame are used in combination to strengthen the compressive strength of the corrugated paper box. The corner reinforcement blocks, the reinforcement connecting rods and the cross reinforcement ribs are used in combination to further strengthen the corrugated paper box, which is conducive to improving the compressive and torsional strength of the corrugated paper box.

[0004] However, although the above-mentioned device utilizes the reinforcing connecting rod and the cross reinforcing ribs to cooperate with each other to improve the compressive resistance of the side of the corrugated cardboard box, this method is not sufficient to ensure the anti-collision performance of all side panels of the corrugated cardboard box when encountering external force collision. In addition, when in use, due to the hollow design of the inner cavity of the corrugated cardboard box, the placed items cannot be reasonably stacked, resulting in a waste of space in the inner cavity of the corrugated cardboard box. Utility Model Content

[0005] The utility model proposes a high-quantity and high-strength corrugated cardboard box, which has the advantages of improving the overall anti-collision performance of the corrugated cardboard box when in use and effectively utilizing the internal space of the corrugated cardboard box to avoid waste, solving the problems of poor anti-collision performance of the corrugated cardboard box and space waste when stacking items in the inner cavity of the corrugated cardboard box.

[0006] The technical solution of the utility model is as follows: a high-quantity and high-strength corrugated cardboard box, comprising a bottom plate, wherein strip grooves are provided in the middle of the front and rear sides of the bottom of the bottom plate, support blocks are fixedly installed at the four corners of the bottom plate, side panels are fixedly installed on the top of the bottom plate, a plurality of slots are provided on the front and rear sides of the inner cavity of the side panels, a placement groove is provided at the top of the inner cavity of the side panels, a storage groove is provided on the left side of the top of the bottom plate, a plurality of partitions are placed in the inner cavity of the storage grooves, a circular hole is provided on the top of the partitions, and a cover plate is detachably installed on the top of the side panels.

[0007] Preferably, the strip groove does not pass through the upper and lower sides of the bottom plate, and the opening of the inner cavity of the strip groove is designed to be arc-shaped. Therefore, when in use, the strip groove opened in the middle of the front and back sides of the bottom plate and the arc-shaped design of the strip groove opening make it easy to pick up the entire corrugated cardboard box through the strip groove when the whole is used.

[0008] Preferably, the height of the inner cavity of the support block is greater than the thickness of the bottom plate, and the shape of the inner cavity of the support block matches the shape of the outer surface of one corner of the bottom plate, so that when in use, the support block is used to wrap the four corners of the bottom plate, and the height of the inner cavity of the support block is used. After the support block and the bottom plate are fixed and bonded, the support block is used to effectively wrap and fix the four corners of the connection between the bottom plate and the side plate, thereby improving the fixing effect between the bottom plate and the side plate, and using the thickness of the support block to avoid direct contact between the bottom plate and the ground, thereby improving the moisture-proof performance of the overall corrugated cardboard box.

[0009] Preferably, the distance between the left and right sides of the slot cavity matches the length between the left and right sides of the partition, the height of the partition is greater than the height of the slot cavity, the slots are evenly distributed on the front and rear sides of the side panel cavity, and the distance between the opposite sides of the front and rear slot cavities matches the width between the front and rear sides of the partition. Therefore, when in use, after the partition is inserted into the slot, the shape of the outer surface of the partition and the shape of the slot cavity are utilized to effectively fill the space of the front and rear slot cavities after the partition is inserted into the slot cavity, thereby dividing the space of the side panel cavity, and utilizing the partition to improve the front and rear anti-collision performance of the side panel when in use.

[0010] Preferably, the width between the front and rear sides of the partition matches the width between the front and rear sides of the placement groove cavity, and the height of the partition is smaller than the distance between the left and right sides of the side panel cavity. Therefore, when in use, the partition is placed in the placement groove cavity to separate the upper and lower sides of the side panel cavity, and the installed partition is used to improve the anti-collision performance between the front and rear sides of the side panel cavity.

[0011] Preferably, the width between the left and right sides of the storage slot inner cavity matches the thickness of all the partitions combined, and the number of partitions matches the number of slots opened on the front or rear side of the side panel inner cavity, so that when in use, the storage slot can effectively accommodate all the partitions.

[0012] Preferably, the inner cavities of the bottom plate, side plates, partition plates and cover plates are all made of corrugated paper, and the outer surfaces of the bottom plate, side plates, partition plates and cover plates are all provided with a waterproof coating. Thus, when in use, the corrugated paper material in the inner cavities of the bottom plate, side plates, partition plates and cover plates is utilized to reduce production costs and facilitate subsequent recycling. At the same time, the waterproof coating on the outer surfaces of the bottom plate, side plates, partition plates and cover plates is utilized to improve the moisture-proof performance of the entire device.

[0013] Preferably, the cross-sectional shape of the inner cavity of the cover plate matches the cross-sectional shape of the outer surface of the side plate, so that when in use, the shape of the cover plate is used to effectively block the top of the side plate, preventing external impurities from entering the interior of the corrugated box or items inside the corrugated box from falling out when the entire corrugated box moves.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] The high-quantity and high-strength corrugated paper box uses a partition structure and a circular hole structure in combination. When in operation, the partition is inserted into the inner cavity of the slot or placed in the inner cavity of the placement groove, and the partition is used to improve the anti-collision performance of the side panel when in use. At the same time, the installed partition can be used to separate the articles in the inner cavity of the side panel to prevent the articles from colliding with each other, thereby improving the utilization rate of the inner cavity of the side panel, thereby achieving the effect of improving the overall anti-collision performance of the corrugated paper box when in use and effectively utilizing the internal space of the corrugated paper box to avoid waste.
