[0012] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0013] Example 1 A modular protective packaging box includes: a box body 1, a box lid 2, an inner rectangular plate 3, an inner airbag 4, a bottom airbag 5, a bottom plate 6, an upper cover 7, an upper airbag 8, and a top plate 9. The inner rectangular plate 3 and the inner airbag 4 are disposed inside the box body 1, with the inner airbag 4 surrounding the outer side of the inner rectangular plate 3. The bottom airbag 5 and the bottom plate 6 are disposed sequentially from bottom to top inside the inner rectangular plate 3. The outer end 71 of the upper cover 7 is located inside the box body 1 and above the inner airbag 4. The inner end 72 of the upper cover 7 is located inside the inner rectangular plate 3. The upper airbag 8 and the top plate 9 are disposed sequentially from top to bottom inside the inner end 72. The box lid 2 is fitted onto the outer end of the box body 1.

[0014] like Figures 1-4 As shown, the working principle of this utility model is as follows: Outer support: The box body resists direct external impacts, and the lid is fitted over the outside of the box body to further reinforce the box structure and also to prevent dust. Peripheral cushioning: The inner rectangular panel forms a placement cavity inside the box, and an inner airbag surrounds the gap between the inner rectangular panel and the box body. The inner airbag absorbs and cancels out the impact force transmitted from the surrounding area through its own elasticity, preventing the force from being directly transmitted to the inner rectangular panel and the contents. Bottom protection: An air bladder is located at the bottom of the inner rectangular panel, which is then covered by a bottom plate. The air bladder forms a bottom buffer layer, while the bottom plate provides a flat support surface for the item. Top protection: The top cover is divided into an outer end and an inner end. The outer end rests on the upper end of the outer airbag, restricting the upward movement of the inner airbag. The inner end extends into the inner rectangular plate. The upper airbag is installed inside first, and then the top plate is covered. The top plate contacts the top of the item, and the upper airbag provides cushioning for the top through elasticity.

[0015] The various combined structures in this utility model achieve six-way buffering in all directions (up, down, left, right, front, and back), effectively resisting collisions and bumps during transportation. It is especially suitable for fragile items and greatly reduces the damage rate of goods. Each component can be disassembled and assembled independently without tools, and damaged airbags can be replaced individually later. The outer box and lid are reinforced, and the inner rectangular plate, bottom plate, and top plate form a double structure of frame and buffer. The components limit each other and are not easy to shift during transportation.

[0016] As a further preferred embodiment, the top cover 7 is symmetrically provided with two sets of pull rings 74. The upper end face of the outer end 71 of the top cover 7 is located below the upper end face of the box body 1, and the pull rings 74 are located between the outer end 71 and the box cover 2. The pull rings provide a convenient point of force for opening the top cover. Users can directly grab the pull rings and pull upwards without having to pry open the edge of the top cover like with traditional boxes. The pull rings are located between the outer end and the box cover and do not protrude outside the box body. When the box cover is placed on the outside of the box body, the inner sidewall of the box cover will cover the outer side of the outer end, and the bottom of the box cover will press against the upper end face of the outer end, forming a limiting structure to prevent the top cover from shifting upwards during transportation.

[0017] As a further preferred embodiment, the inner rectangular plate 3 has slots 31 on its four sides below, and the base plate 6 has inserts 61 that match the slots 31. When installing the base plate, simply align the insert with the slot and insert it to quickly determine the position of the base plate, avoiding tilting or lateral shifting of the base plate; after the insert is inserted into the slot, the base plate and the inner rectangular plate form a stable lower frame.

[0018] As a further preferred embodiment, the inner end portion 72 is provided with a second slot 73 around its inner perimeter, and the top plate 9 is provided with a second insertion block 91 that matches the second slot 73. The second insertion block is inserted into the second slot to quickly position the top plate at the inner end portion, ensuring that the top plate completely covers the airbag.

[0019] As a further preferred embodiment, the inner airbag 4 includes airbag one 41, airbag two 42, airbag three 43, and airbag four 44, which are sequentially arranged around the area between the box body 1 and the inner rectangular plate 3. The four sets of independent airbags correspond to the four sides of the inner rectangular plate and are installed in the gaps between the box body and the inner rectangular plate, respectively. It is not necessary to insert the entire airbag at once; they can be inserted into the gaps one by one to adapt to different box sizes. If one airbag leaks or ruptures, the other three can still inflate, ensuring that the protection of the corresponding side remains effective.

[0020] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
