Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically to a multi-layer protective cardboard box. Background Technology

[0002] In the logistics and packaging industry, cardboard boxes are the most basic and widely used containers, and their core function is to provide safe protection and convenient transportation support for the contents.

[0003] However, traditional cardboard boxes generally use a single-layer or simple composite structure, with limited material strength and a lack of targeted protective design. This makes them prone to deformation, damage, or even collapse when faced with stacking pressure, transportation bumps, or accidental collisions, directly causing a chain reaction of damage to the goods inside, increased packaging costs, and reduced logistics efficiency.

[0004] Therefore, a multi-layered protective cardboard box is proposed to solve the problems mentioned above. Utility Model Content

[0007] Preferably, the inner layer is made of honeycomb paperboard, and the protective layer is made of foam board.

[0008] Preferably, the cushioning layer is made of cardboard, and the reinforcing layer is made of thick corrugated cardboard.

[0009] Preferably, the waterproof layer is made of epoxy resin, and the cushioning pad is made of rubber.

[0010] Preferably, the frame is square and is horizontally positioned.

[0011] Preferably, there are five frames, with a connecting rod fixedly installed on the inner wall of the fifth frame, and the columns are vertically arranged, each column being a cylindrical rod, and there are four columns in total.

[0012] Preferably, the reinforcing rod is X-shaped, and there are two reinforcing rods.

[0013] Compared with the prior art, this utility model provides a multi-layer protective cardboard box, which has the following beneficial effects: 1. This utility model features an inner layer made of honeycomb cardboard. The honeycomb structure provides excellent impact protection and cushioning, while the honeycomb cardboard also has strong compression resistance. The protective layer increases the buffer space around the items, ensuring that the products are not damaged by the shaking of the carton. The buffer layer provides additional cushioning and effectively absorbs external impacts. The reinforcing layer provides basic compression resistance and cushioning, effectively absorbing external impacts and increasing the carton's compression strength. The waterproof layer improves the carton's waterproof performance and enhances its wear resistance, preventing damage to the outer carton when subjected to external impacts, thus providing basic protection for the internal items. 2. This utility model, by setting up a protective mechanism, is used to increase the strength of the cardboard box and facilitate its use.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0017] 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.

[0018] Example: Please see Figure 1 - Figure 4 This embodiment of a multi-layer protective cardboard box includes a box body 1, within which a protective mechanism 3 is provided. The protective mechanism 3 increases the strength of the cardboard box, facilitating its use. A cushioning pad 2 is inserted within the protective mechanism 3 to enhance the box's cushioning performance and prevent items from colliding with it. The box body 1 includes an inner layer 11, which is made of honeycomb cardboard. The honeycomb structure provides excellent impact protection and cushioning, while also exhibiting strong compression resistance. A protective layer 12 is fixedly installed on the surface of the inner layer 11, increasing the buffer space around the items. To ensure that the product is not damaged by the shaking of the carton inside, a buffer layer 13 is fixedly installed on the surface of the protective layer 12. The buffer layer 13 provides additional cushioning and can effectively absorb external impact. A reinforcing layer 14 is provided on the buffer layer 13. The reinforcing layer 14 provides basic compression resistance and cushioning, and can effectively absorb external impact and increase the compression strength of the carton. A waterproof layer 15 is fixedly installed on the reinforcing layer 14. The waterproof layer 15 improves the waterproof performance of the carton and also enhances its wear resistance, preventing the outer carton from being damaged when subjected to external impact, thus providing basic protection for the contents. The protective mechanism 3 includes a frame 32, which is fixedly installed inside the inner layer 11. Columns 31 and reinforcing rods 33 are fixedly installed between the frames 32.
