A Velcro loop fastener 8 is glued to the side of each Velcro hook-and-loop fastener 7 away from the box body 1. A folded edge strap 9 is fixedly connected to the side of each Velcro loop fastener 8 away from the Velcro hook-and-loop fastener 7. A bottom plate 10 is fixedly connected to the bottom of the several folded edge straps 9. The top surface of the bottom plate 10 is attached to the bottom surface of the supporting bottom plate 6.

[0025] As an optional technical solution of this utility model, the bottom plate 10 is made of high-density polyethylene material. The bottom surface of the bottom plate 10 is provided with wear-resistant and anti-slip texture. The bottom plate 10 is made of high-density polyethylene material and is provided with wear-resistant and anti-slip texture, which gives it excellent wear resistance and anti-slip properties. It can effectively resist ground friction and wear during forklift handling, while ensuring the stability of the box during transportation and extending the service life of the bottom plate.

[0026] As an optional technical solution of this utility model, the supporting base plate 6 is a honeycomb aluminum plate structure, and the surface of the supporting base plate 6 is coated with an anti-corrosion coating. The supporting base plate 6 adopts a honeycomb aluminum plate structure and is coated with an anti-corrosion coating, which not only ensures the lightweight characteristics of the base plate, but also provides excellent compressive strength and load-bearing capacity. The anti-corrosion coating effectively prevents the erosion of the aluminum plate by the humid environment, so that the base plate maintains its structural integrity during long-term use.

[0027] As an optional technical solution of this utility model, the waterproof bag 5 is made of PVC composite fabric, and an elastic limiting band 11 is fixedly connected to the inner wall of the box body 1. The bottom surface of the elastic limiting band 11 is attached to the top surface of the box bottom plate 10. The waterproof bag 5 is slidably connected to the elastic limiting band 11. The design of the waterproof bag 5 using PVC composite fabric in conjunction with the elastic limiting band 11 not only achieves good waterproof performance, but also ensures that the internal items will not shift during transportation by attaching and fixing the elastic limiting band 11 to the box bottom plate 10. At the same time, it facilitates the operation when replacing the box bottom plate.

[0028] As an optional technical scheme of the utility model, the top cover 2 is made of transparent polycarbonate material, the edge of the top cover 2 is provided with a reinforcing frame, the design of the transparent polycarbonate top cover 2 cooperating with the reinforcing frame is convenient for the user to intuitively check the condition of the articles in the box, and the edge reinforcing frame improves the structural strength of the top cover, so that the top cover can withstand certain external impact without being easily damaged.

[0029] As an optional technical scheme of the utility model, the edge folding belt 9 is made of high-strength nylon webbing, and the connecting part of the edge folding belt 9 and the bottom plate 10 is reinforced by double sewing, so that the tensile strength of the connecting part of the edge folding belt and the bottom plate 10 is greatly improved, and tearing or opening of the connecting part during frequent replacement of the bottom plate is avoided.

[0030] As an optional technical scheme of the utility model, the material of the annular belt 3 is nylon webbing, and the end of the pull belt 4 is provided with an anti-skid handle, so that the carrying operation is more convenient and labor-saving, the anti-skid handle improves the gripping comfort and safety, and the nylon material ensures the durability of the pull belt during long-term use.

[0031] A logistics box convenient for replacing the bottom plate, and the working principle is as follows:

[0032] 1): when the bottom plate 10 is worn due to long-term use, the magic tape 8 is only peeled off from the hook tape 7, and the entire bottom plate 10 can be removed and replaced.

[0033] 2): the design of the elastic limiting belt 11 keeps the waterproof bag 5 and the bearing bottom plate 6 stable during replacement, avoiding displacement of the internal articles.

[0034] 3): when replacing the new bottom plate 10, the hook tape 7 on the outer surface of the box body 1 is only pressed on the hook tape 7 on the outer surface of the box body 1.

[0035] In summary, the logistics box with replaceable bottom is designed with detachable connection of the hook surface tape 7 and the loop surface tape 8, effectively solving the problem of traditional logistics box bottom wear and tear. When the bottom plate 10 is worn out after long-term use, simply peel off the loop surface tape 8 from the hook surface tape 7, and the entire bottom plate 10 can be removed and replaced. The design of the elastic limiting belt 11 keeps the waterproof bag 5 and the load-bearing bottom plate 6 stable during replacement, avoiding internal item displacement. When replacing the new bottom plate 10, simply press the loop surface tape 8 on the folded edge belt 9 onto the hook surface tape 7 on the outer surface of the box body 1 to complete the installation. This modular design makes the bottom replacement operation simple and fast, without the need for professional tools, greatly extending the service life of the box 1, while the box bottom plate 10 can be selected according to different use scenarios, improving the product's applicability and economy, and the multi-layer composite structure design realizes excellent durability and functionality. The bottom plate 10 is made of high-density polyethylene material with wear-resistant and anti-slip patterns, which can withstand frequent ground dragging; the honeycomb aluminum plate structure of the load-bearing bottom plate 6 reduces the overall weight while ensuring strength; the PVC composite fabric of the waterproof bag 5 and the elastic limiting belt 11 work together to ensure the waterproof and moisture-proof of the internal items; the transparent polycarbonate top cover 2 facilitates quick viewing of the contents of the box. The reinforced design of the ring belt 3 and the pull belt 4 makes it easier and more labor-saving to carry. Through optimized combination of various components, the stability of the overall structure is maintained, and the functionality is modularized, making the product significantly improved in durability, practicality and maintenance convenience.
