Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, and more specifically, to a waterproof, pressure-resistant and environmentally friendly corrugated paper packaging box. Background Art

[0002] Corrugated cardboard is die-cut, creased, and then stapled or glued together to create corrugated boxes. Corrugated boxes are the most widely used packaging product, consistently leading the way in terms of volume. This includes calcium-plastic corrugated boxes. For over half a century, corrugated boxes, with their superior performance and excellent processing properties, have gradually replaced wooden boxes and other transport containers, becoming the mainstay of transportation packaging. In addition to protecting products and facilitating storage and transportation, they also enhance product aesthetics and promote product promotion. Corrugated boxes are environmentally friendly and easy to handle and transport.

[0003] After searching, for example, a Chinese patent application with publication number CN221699536U discloses a waterproof, pressure-resistant and environmentally friendly corrugated paper packaging box, in which a layer of honeycomb permeable board is provided on the lower surface of the corrugated paper box body, and the honeycomb permeable board is set as a honeycomb structured cardboard, which can not only be more breathable, but also allow water to precipitate faster. Combined with multiple support frames fixed to the bottom surface of the corrugated paper box body, the support frames are fixed at the four corners of the bottom surface of the corrugated paper box body, which can provide better support for the corrugated paper box body, and a permeable groove is provided through the outer wall of the support frame. Therefore, when the corrugated paper box body is placed on the ground with water, since the contact area between the support frame itself and the ground is very small, the bottom surface of the corrugated paper box body is minimized from being damp, and the permeable groove facilitates the passage of flowing water on the ground to prevent the flowing water from being blocked by the corrugated paper box body, causing the bottom surface of the corrugated paper box body to be continuously damp.

[0004] However, the above solution improves the firmness by using the support frame, but it is difficult to fold the packaging box during production or recycling, thereby taking up a lot of space. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a waterproof, pressure-resistant and environmentally friendly corrugated paper packaging box, the technical problems to be solved are: it is difficult to fold and recycle, and it occupies a large space.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a waterproof, pressure-resistant and environmentally friendly corrugated paper packaging box, comprising a box body made of corrugated paper:

[0007] Four lower cover plates are fixedly provided at the lower end of the box body, and the four lower cover plates are folded;

[0008] The inner side of the box body is provided with a folding reinforcement device capable of reinforcing the box body, which is used to reinforce the load-bearing hardness of the box body and enable the box body to be folded;

[0009] The folding reinforcement device includes four rotation grooves, and hinge columns are respectively inserted into the inner sides of the four rotation grooves;

[0010] The lower end of the lower cover plate is provided with a waterproof isolation device capable of preventing the bottom end of the box from getting wet, and is used to isolate the contact between the ground and the bottom end of the box.

[0011] In a preferred embodiment, the inner wall of the box is provided with four receiving grooves, the four receiving grooves are located between the four rotating grooves, and a connecting plate is movably provided inside the receiving groove.

[0012] In a preferred embodiment, a hinge sleeve is fixedly provided at one end of the connecting plate, and a hinge block is fixedly provided at the other end of the connecting plate, and the hinge sleeve and the hinge block are adapted to each other.

[0013] In a preferred embodiment, the four connecting plates are arranged in a quadrilateral, the hinge sleeve and the hinge block are located inside the rotation groove, and the hinge column passes through the inside of the hinge sleeve and the hinge block.

[0014] In a preferred embodiment, the waterproof isolation device includes two L-shaped plates, and the two L-shaped plates are fixedly arranged at the lower ends of the two lower cover plates.

[0015] In a preferred embodiment, a moisture-proof plate is movably provided at the lower end of the lower cover plate, a porous plastic plate is fixedly provided at the lower end of the moisture-proof plate, a slot is provided between the moisture-proof plate and the porous plastic plate, and the slot is adapted to the L-shaped plate.

[0016] In a preferred embodiment, four upper cover plates are fixedly provided on the upper end of the box body.

[0017] The technical effects and advantages of this utility model are:

[0018] 1. The utility model increases the load-bearing capacity of the box body and achieves a compression-resistant effect by inserting hinged columns into the four corners of the box body. Four connecting plates are placed around the storage slot, and hinged columns are inserted into the hinge sleeve and the hinge block to achieve the rotation of the hinge sleeve and the hinge block. When the box body is retracted, the quadrilateral box body can be folded diagonally, thereby reducing the space occupied by the utility model.

[0019] 2. The utility model inserts two L-shaped plates into the slots, thereby installing the porous plastic plate and the moisture-proof plate at the lower end of the utility model, so that the folding of the lower cover plate can be restricted, reducing the use of tape at the bottom end of the utility model, and separating the bottom end of the utility model from the ground, preventing the utility model from being damaged by moisture due to moisture on the ground, thereby improving the overall waterproof ability of the utility model.
