[0023] refer to Figures 1-3 The contents stabilizing component 5 includes a folding plate 51 that is snapped into the inside of the box body 1. The folding plate is made of cardboard so that it still has support after being bent. Both sides of the folding plate 51 can be bent to connect to connecting plates 52. The outer side of the connecting plates 52 is bent to form a limiting edge 53. Both sides of the inside of the box body 1 are fixedly connected to limiting protrusions 54. Multiple limiting protrusions 54 are provided, and the limiting edge 53 is snapped between multiple limiting protrusions 54. After the items are placed inside the box body 1, the folding plate 51 can be adjusted according to the area of ​​the items inside the box body 1. When the items are smaller than the box body 1, the folding plate 51 can be folded. During the folding process, the folding plate 51 should contact the items on one side. Then, the limiting edges 53 connected to both sides of the folding plate 51 are inserted between the multiple limiting protrusions 54 on both sides of the box body 1. After the insertion is completed, the folding plate 51 can be fixed. This makes it easy to fix the items inside the box body 1 when packaging smaller items, thus achieving a convenient use.

[0024] refer to Figures 1-3 The bottom of the box 1 is movably connected to a corrugated cardboard 4, which is located directly below the contents stabilizing component 5. A waterproof base 3 is fixedly connected to the bottom perimeter of the box 1. The corrugated cardboard 4 mainly provides a cushioning effect for the items inside the box 1. The cushioning structure of the corrugated cardboard 4 can absorb a large amount of impact energy and play a good vibration isolation role, thereby avoiding damage to the contents caused by impact and vibration. At the same time, the waterproof base 3 can prevent the box 1 from contacting the ground, thus preventing the ground moisture from being transmitted to the box 1 and causing damage to the box 1.

[0025] refer to Figure 1 , Figure 2 and Figure 5Inside the box 1, a square cardboard 10 is movably connected to the upper end of the contents stabilizing member 5. A reinforcing paper tube 8 is fixedly connected inside the square cardboard 10. After the items are placed, the square cardboard 10 can be placed on the upper end of the contents stabilizing member 5. The reinforcing paper tube 8 between the square cardboards can enhance the compressive strength of the box 1. Compared with the cardboard, the paper tube of this device has a stronger compressive strength.

[0026] refer to Figures 1-2 Both sides of the box 1 are provided with round holes 6, and plastic plates 7 are fixedly connected inside the round holes 6. Both sides of the plastic plates 7 cover the round holes 6. When moving the carton, the box 1 can be moved by inserting your hand into the round holes 6. The plastic plates 7 can increase the contact area between your fingers and the inner wall of the round holes 6, thereby increasing the pressure resistance of the round holes 6.

[0027] refer to Figure 3 and Figure 5 Inside the box 1, on both sides away from the content stabilizer 5, there are fixed sponge pads 11. The inner side of the sponge pads 11 is connected to a buffer plate 12, which covers the round hole 6. Under the action of the sponge pads 11 and the buffer plate 12, the sides of the contents inside the box 1 can be cushioned, avoiding the damage to the contents inside the box 1 caused by the impact on the sides of the box 1. At the same time, after the buffer plate 12 covers the round hole 6, it can prevent external water from contacting the contents inside the box through the round hole 6 and causing damage to the contents, thus further increasing the practicality of the device.

[0028] refer to Figure 4The waterproof composite layer 112 includes a waterproof layer 113 and a wear-resistant layer 114. The outer side of the corrugated paper base layer 111 is fixedly connected to the waterproof layer 113, and the outer side of the waterproof layer 113 is fixedly connected to the wear-resistant layer 114. The waterproof layer 113 is an acrylic waterproof coating, and the wear-resistant layer 114 is a metal-ceramic coating. The metal-ceramic coating is used to prepare a wear-resistant coating that plays a role in many aspects such as resistance to adhesive wear, abrasive wear, fiber wear, and micro-vibration wear, thereby increasing the wear resistance of the box 1. Secondly, the acrylic waterproof coating has excellent waterproof performance, which can effectively prevent water from penetrating to the surface of the box 1 and prevent water from eroding and damaging the structure of the box 1. The corrugated paper layer is composed of a corrugated core paper interlayer and a cardboard layer. Kraft paper is bonded to the upper and lower surfaces of the corrugated paper layer to form the corrugated paper base layer. Operating principle and advantages: First, open the lid 2. Then, place the corrugated cardboard 4 at the bottom of the box 1. Next, place the items inside the box 1. After placing the items, adjust the folding plate 51 according to the area of ​​the items inside the box 1. If the items are smaller than the box 1, fold the folding plate 51 to widen its width. During folding, ensure one side of the folding plate 51 contacts the items. Then, insert the limiting edges 53 connected to both sides of the folding plate 51 into the multiple limiting protrusions 54 on both sides of the box 1. After insertion, fix the folding plate 51. This allows for easy fixing of smaller items inside the box 1, facilitating convenient use. After limiting the items, place the square cardboard 10 inside the box. The upper end of the stabilizer 5, and the first reinforcing paper tube 8 and the second reinforcing paper tube 9 placed between the cardboard, can enhance the compressive strength of the box body 1. Compared with the cardboard, the paper tube of this device has a stronger compressive strength. With the action of the sponge pad 11 and the buffer plate 12, it can cushion the sides of the contents inside the box body 1, avoiding the phenomenon of damage to the contents inside the box body 1 due to impact on the sides of the box body 1. At the same time, after the buffer plate 12 wraps the round hole 6, it can prevent external water from contacting the contents inside the round hole 6 and causing damage to the contents, thus further increasing the practicality of the device. When moving the cardboard box, the box body 1 can be moved by inserting the hand into the inside of the round hole 6. With the action of the plastic plate 7, the contact area between the fingers and the inner wall of the round hole 6 can be increased, thereby increasing the compressive strength of the round hole 6.
