Description

Technical Field

[0001] The present invention relates to the technical field of packing boxes, and particularly to a reusable cardboard box for logistics. Background Art

[0002] Chinese Patent Grant Publication No. CN 210455611 U, with the grant publication date of May 5, 2020, discloses an easily stackable cardboard box and a cardboard box stacking and fixing structure. It includes a cardboard box enclosure, a cardboard box upper cover, and a cardboard box lower cover. The outer top surface of the cardboard box upper cover is provided with a fixedly connected reinforcing corner protector, and the outer bottom surface of the cardboard box lower cover is provided with a fixedly connected clamping plate. When two such easily stackable cardboard boxes are stacked vertically with their four sides aligned, four positioning corner protectors are respectively provided at the four corners of the connection. The positioning corner protectors are fixed to the four vertical right-angle sides of the connection of the two easily stackable cardboard boxes by a packing belt. The packing belt respectively fixes the upper and lower layer packages and the paper corner protectors; the winding film wraps around the circumference of the cardboard box. This utility model overcomes the problems of the heavy wooden box packaging and insufficient load-bearing capacity of the cardboard box packaging in the traditional packaging, facilitates the operation, and improves the production efficiency; the upper and lower layers are stacked and placed, which can make more reasonable use of space, especially suitable for shipping by container by sea or land, and saves the transportation cost of the product. The defects of this prior art are as follows: 1. The clamping plate needs to be fixed by self-tapping screws, which reduces the disassembly and assembly effect; 2. It is only convenient for vertical stacking and placement. When arranged horizontally, once the horizontal placement is irregular, it will directly affect the neatness of the stacking and placement; 3. An additional packing operation is required, such as using tape or bundling tape, etc., which reduces the packing speed. In view of this situation, it is urgent to improve. Summary of the Invention

[0003] Based on this, the purpose of the present invention is to provide a reusable cardboard box for logistics, the feet are easy to disassemble and assemble, can ensure regular stacking and placement, are self-equipped with elastic straps for sealing and fixing, improve the packing speed, and have good shock absorption and buffering functions.

A plurality of mounting convex grains are arranged in a rectangular partial area on one side surface of the buffer mounting plate facing the inner cavity of the packaging box body.

[0009] Preferably, when it is necessary to improve the stability of the items placed in the packaging box body, a buffer inner card is arranged on the corresponding buffer mounting plate, and a convex grain card slot corresponding to the mounting convex grains is arranged on one side surface of the buffer inner card.

[0010] Preferably, a storage groove is formed in the middle of the inner side surface of the outer flip cover. Outer flip support plates are arranged on opposite sides of the storage groove. When the packaging box body is in a non-sealed state, the outer flip support plates are correspondingly stored in the storage groove. When the packaging box body is in a sealed state, the outer flip support plates are in a vertically flipped state.

[0011] Preferably, a rough anti-slip surface is formed along the length direction of the bottom of the second fitting groove.

[0012] Preferably, a magnet A is arranged at the top of the inner cavity of the storage groove, and a magnet B matched with the magnet A is arranged on the free end of the outward-turning support plate and on the side close to the inner cavity of the storage groove.

[0013] Preferably, the bottom of the packaging box body is provided with a honeycomb cardboard layer.

[0014] Preferably, a waterproof layer is coated on the outer side surface of the packaging box body.
