Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a multi-layered cushioning structure for logistics paper packaging boxes includes a packaging box body 1. Sliding grooves 2 are provided at each of the four corners of the packaging box body 1. An inner cushioning mechanism 7 is provided inside the packaging box body 1. The inner cushioning mechanism 7 includes a lower airbag 71 placed at the bottom of the inner side of the packaging box body 1. An inner compartment 72 is placed inside the packaging box body 1. There is a gap between the packaging box body 1 and the inner compartment 72. A front airbag 73 is placed in the gap on the front side between the packaging box body 1 and the inner compartment 72. A side airbag 74 is placed in the gap on one side between the packaging box body 1 and the inner compartment 72. A main connecting pipe 75 is fixedly connected to the lower end of the front airbag 73. A secondary connecting pipe 76 is fixedly connected to the lower end of the side airbag 74. An inflation pipe 77 is fixedly connected to the front end of the lower airbag 71. A sliding frame 79 is slidably connected to the inner side of the sliding groove 2. A corresponding rod 710 is slidably connected to the inner side of the sliding frame 79.

[0021] In this embodiment, the inflation tube 77 penetrates the interior of the packaging box body 1 and is fixedly connected to the packaging box body 1. A cap tube buckle 78 is threadedly installed on the outer side of the inflation tube 77 near the front side of the packaging box body 1. The rear end of the main connecting tube 75 is fixedly connected to the front end of the lower airbag 71. The main connecting tube 75 is connected to the front airbag 73 and the lower airbag 71. One end of the auxiliary connecting tube 76 is fixedly connected to one end of the lower airbag 71. The auxiliary connecting tube 76 is connected to the side airbag 74 and the lower airbag 71. The main connecting tube 75 and the auxiliary connecting tube 76 are both L-shaped. There are two sets of the main connecting tube 75, the auxiliary connecting tube 76, the front airbag 73, and the side airbag 74. One end of the corresponding rod 710 is fixedly connected to the corner of the inner compartment 72.

[0022] Specifically, a protective film is wrapped around the surface of the item to be shipped via logistics. The item is then placed inside the inner compartment 72, and the inner compartment 72 is placed inside the packaging box body 1. The inner compartment 72 is positioned so that its sides and bottom contact the two sets of front airbags 73, the two sets of side airbags 74, and the lower airbag 71. The cap tube buckle 78 is then unscrewed. The air pump is then connected to the inflation tube 77, and the air pump inflates the lower airbag 71 through the inflation tube 77. The gas inside the lower airbag 71 is then inflated through the main connecting tube 75. The auxiliary connecting pipe 76 flows into the front airbag 73 and the side airbags 74, simultaneously inflating the lower airbag 71, the two sets of front airbags 73, and the two sets of side airbags 74. This causes the lower airbag 71, the two sets of front airbags 73, and the two sets of side airbags 74 to secure the internal compartment 72 inside the packaging box body 1. Then, the inflation cylinder is removed, and the cap tube buckle 78 is screwed onto the inflation pipe 77, creating an independent space for the internal compartment 72 within the packaging box body 1. Furthermore, during transportation, especially when the logistics vehicle is traveling on poor road conditions, this ensures... When the inner compartment 72 shakes and compresses the front airbag 73, a gap is created between the rear side of the inner compartment 72 and the packaging box body 1. At this time, the gas in the front airbag 73 flows through the lower airbag 71 to another set of front airbags 73, thus blocking the gap between the inner compartment 72 and the packaging box body 1. This prevents the inner compartment 72 from forming a gap between the inner compartment 72 and the packaging box body 1, and also prevents the inner compartment 72 from repeatedly shaking within the packaging box body 1. By compressing the front airbag 73 forward and causing the gas in the front airbag 73 to flow through the main connecting pipe 75 to the lower airbag 71, and then flowing through the other set of main connecting pipes 75 to the other set of front airbags 73, the gap between the inner compartment 72 and the packaging box body 1 can be blocked by the other set of front airbags 73, thereby preventing the inner compartment 72 from forming a gap between the inner compartment 72 and the packaging box body 1, and preventing the inner compartment 72 from repeatedly shaking within the packaging box body 1.

[0023] In this embodiment, a short side cover 3 is fixedly connected to the upper end of the packaging box body 1, and a long side cover 4 is fixedly connected to the front side of the upper end of the packaging box body 1 near the short side cover 3. The long side cover 4 and the short side cover 3 are perpendicular to each other. A reinforcing base plate 5 is placed at the lower end of the packaging box body 1. Buckles 6 are attached to the lower side of the four corners of the packaging box body 1 near the sliding groove 2. The lower ends of the four sets of buckles 6 are fixedly connected to the upper end of the reinforcing base plate 5 near the outer side of the packaging box body 1.

[0024] Specifically, the packaging box body 1 is placed on the reinforcing base plate 5, which makes the packaging box body 1 fit into the four sets of buckles 6. Then, the short side cover 3 and the long side cover 4 are respectively placed on the packaging box body 1, and the short side cover 3 and the long side cover 4 are sealed with tape, so that the internal compartment 72 forms an independent space inside the packaging box body 1. Then, the reinforcing base plate 5 is placed in the logistics vehicle, and the packaging box body 1 is stacked in sequence to facilitate its transportation.

[0025] Working principle:

[0026] In use, the worker first wraps a protective film around the surface of the items to be shipped, then places the items into the inner compartment 72, and then places the inner compartment 72 into the packaging box body 1, ensuring that the inner compartment 72's sides and bottom contact the two sets of front airbags 73, the two sets of side airbags 74, and the lower airbag 71 respectively. Then, the packaging box body 1 is placed on the reinforced base plate 5, which secures the packaging box body 1 within the four sets of clips 6. The cap tube clip 78 is then unscrewed, and the air pump is connected to the inflation hose 77, allowing the air pump to inflate the lower airbag 71 through the inflation hose 77. The gas inside the lower airbag 71 then passes through the main connecting pipe 75 and the auxiliary connecting pipe 76. The connecting pipe 76 flows into the front airbag 73 and the side airbag 74, simultaneously inflating the lower airbag 71, the two sets of front airbags 73, and the two sets of side airbags 74. This causes the lower airbag 71, the two sets of front airbags 73, and the two sets of side airbags 74 to secure the internal compartment 72 inside the packaging box body 1. Then, the air pump is removed, and the cap tube buckle 78 is screwed onto the air hose 77. Next, the short side cover 3 and the long side cover 4 are placed on the packaging box body 1, and the short side cover 3 and the long side cover 4 are sealed with tape. This creates an independent space for the internal compartment 72 inside the packaging box body 1. Finally, the reinforcing base plate 5 is placed in the logistics vehicle, and the packaging boxes are stacked one after another. In the case of the packaging box body 1, during transportation, when the logistics vehicle is traveling on poor road conditions, the inner compartment 72 shakes, causing the inner compartment 72 to push the corresponding rod 710 to move. This, in turn, causes the inner compartment 72 to push the sliding frame 79 to slide within the sliding groove 2, and compresses the front airbag 73. This creates a gap between the rear of the inner compartment 72 and the packaging box body 1. At this point, the gas in the front airbag 73 flows through the lower airbag 71 back to another set of front airbags 73, which then block the gap between the inner compartment 72 and the packaging box body 1, thus preventing the inner compartment 72 from... To prevent gaps between the packaging box body 1 and the inner compartment 72 from repeatedly shaking within the packaging box body 1, the inner compartment 72 is used to press the front airbag 73 forward. This causes the gas in the front airbag 73 to flow through the main connecting pipe 75 to the lower airbag 71, and then through another set of main connecting pipes 75 to another set of front airbags 73. This facilitates the other set of front airbags 73 blocking the gap between the inner compartment 72 and the packaging box body 1, thereby preventing gaps between the inner compartment 72 and the packaging box body 1 and preventing the inner compartment 72 from repeatedly shaking within the packaging box body 1.
