[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, this utility model provides a waterproof, moisture-proof and pressure-resistant lightweight calcium board turnover packaging box, including a packaging box body 1, and a pressure-resistant component 2 installed on the surface of the packaging box body 1;

[0025] The anti-compression component 2 includes a reinforcing seat 21. The reinforcing seat 21 is installed on the bottom surface of the packaging box body 1. A folded inner cardboard 22 is installed on the upper surface of the packaging box body 1. Several arc-shaped spring plates 23 are evenly distributed on the surface of the folded inner cardboard 22. A folded outer cardboard 24 is installed on the outer surface of the folded inner cardboard 22. A replacement component 3 is installed on the surface of the packaging box body 1. This can prevent the top of the packaging box body 1 from collapsing, being damaged, or deforming during the stacking process, thereby improving the service life of the packaging box body 1.

[0026] Specifically, the packaging box body 1 is symmetrically equipped with diagonal reinforcing plates 25 inside. The diagonal reinforcing plates 25 are fitted into the inside of the packaging box body 1, thereby improving the overall structural stability of the packaging box body 1 and enhancing its pressure resistance.

[0027] like Figures 1 to 4As shown, the surface of the main body 1 of the packaging box is coated with a composite protective coating 26, which consists of a penetrating waterproof bottom layer, a nano-silane waterproof intermediate layer, and a high-elasticity polyurethane surface layer from the inside out. This coating can waterproof and moisture-proof the main body 1 of the packaging box, prevent the main body 1 of the packaging box from being affected by moisture, and improve the service life of the main body 1 of the packaging box.

[0028] Furthermore, corner protectors 27 are installed at the corners of the main body 1 of the packaging box, thereby protecting the corners of the main body 1 of the packaging box.

[0029] It is worth noting that several arc-shaped elastic plates 23 are evenly arranged around the four sides of the folded inner cardboard 22, which can disperse the downward pressure and further improve the protection effect on the main body of the packaging box 1.

[0030] like Figures 1 to 4 As shown, the replacement component 3 includes a connecting strip 31. The connecting strip 31 is symmetrically installed on the bottom surface of the folded inner cardboard 22. The inside of the packaging box body 1 is provided with a slot that matches the connecting strip 31. The connecting strip 31 is engaged in this slot, so that the damaged folded inner cardboard 22 can be replaced as a whole, avoiding the need to discard the folded inner cardboard 22 and the packaging box body 1 as a whole, thereby saving resources.

[0031] It is worth emphasizing that a magnetic absorbing piece 32 is installed in the groove on the surface of the connecting strip 31, and a magnetic absorbing piece 33 is installed in the slot inside the main body of the packaging box 1. The magnetic absorbing piece 32 and the magnetic absorbing piece 33 are magnetically attracted to each other, thereby improving the connection between the folded inner cardboard 22 and the main body of the packaging box 1.

[0032] Among them, the structure of the main body of the packaging box 1 is existing technology, which is a lightweight calcium board. Its working principle is a well-known technology, and the appropriate model is selected according to the actual use.

[0033] Working principle and process: The goods are placed inside the main body 1 of the packaging box and the lid is closed. When multiple layers of the main body 1 of the packaging box are stacked, the inner folded cardboard 22 and the arc-shaped elastic plate 23 of the lower main body 1 of the packaging box bear the pressure of the upper main body 1 of the packaging box. The arc-shaped elastic plate 23 is evenly distributed on the surface of the inner folded cardboard 22. The arc-shaped elastic plate 23 is made of plastic and is fixed by adhesive. The arc-shaped elastic plate 23 disperses the pressure through elastic deformation to prevent the top of the main body 1 of the packaging box from collapsing. At the same time, the inner folded cardboard 22 and the outer folded cardboard 24 further disperse the pressure through the deformation of the folded structure to protect the top of the main body 1 of the packaging box.

[0034] After the external force disappears, the arc-shaped spring plate 23 returns to its original shape by its own elasticity, and the inner folded cardboard 22 and the outer folded cardboard 24 are reset synchronously to maintain the structural stability of the main body 1 of the packaging box.

[0035] The diagonal reinforcing plate 25 is symmetrically fitted inside the main body 1 of the packaging box, forming a triangular support structure with the box wall. It utilizes the principle of triangular stability. When the main body 1 of the packaging box is subjected to lateral or longitudinal pressure, the diagonal reinforcing plate 25 distributes the force to each surface of the main body 1 of the packaging box through cross support, preventing the side wall or top from denting.

[0036] The coating penetrates the pores on the surface of the calcium board, forming a sealing film that prevents moisture from seeping into the board.

[0037] Nano-silane waterproof intermediate layer: Silane molecules react with water molecules to form a hydrophobic layer, creating a "lotus effect" on the surface, where rainwater or moisture condenses into water droplets and slides off.

[0038] High-elasticity polyurethane surface layer: An elastic film covers the surface, isolating external moisture while resisting friction and scratches, protecting the inner coating layer;

[0039] The corner protector 27 can protect the corners of the main body 1 of the packaging box;

[0040] When disassembling the inner folding cardboard 22 from the main body of the packaging box 1, first pull the inner folding cardboard 22 as a whole. At this time, the inner folding cardboard 22 will cause the connecting strip 31 to disengage from the slot inside the main body of the packaging box 1. The magnetic locating piece 1 32 and the magnetic locating piece 2 33 will disengage from the magnetic state. Pull the connecting strip 31 out of the slot of the box body, so that the inner folding cardboard 22 as a whole is separated from the main body of the packaging box 1. Then replace it with a new inner folding cardboard 22 as a whole.

[0041] At this point, the connecting strip 31 is inserted into the slot opened in the main body 1 of the packaging box, and the magnetic absorbing piece 32 and the magnetic absorbing piece 33 attract each other, thereby connecting the folded inner cardboard 22 to the main body 1 of the packaging box.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
