Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper packaging boxes, specifically a pressure-resistant and shockproof corrugated paper packaging box. Background Technology

[0002] Corrugated cardboard boxes are packaging containers made primarily of corrugated cardboard, a composite material consisting of one or more layers of corrugated core paper bonded together with one or more layers of sheet paper (coating paper, liner paper) using adhesives. This structure gives the packaging box good strength, elasticity, and cushioning properties, effectively protecting the product inside.

[0003] Corrugated core paper is a crucial component of corrugated cardboard. Its wavy shape and thickness determine the cushioning performance and strength of the cardboard. Common corrugated shapes include U-shaped, V-shaped, and UV-shaped. U-shaped corrugations offer good elasticity and excellent cushioning; V-shaped corrugations have high stiffness and compressive strength; and UV-shaped corrugations combine the advantages of both. The basis weight (weight per square meter) and number of layers of corrugated core paper also vary, but existing corrugated cardboard packaging box structures do not offer ideal compressive strength and are easily deformed during transportation.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing corrugated cardboard packaging boxes. Utility Model Content

[0005] To address the technical problem that existing corrugated cardboard packaging boxes have insufficient compressive strength and are prone to deformation during transportation, this utility model provides a compression-resistant and shockproof corrugated cardboard packaging box.

[0006] This utility model is achieved using the following technical solution: a pressure-resistant and shockproof corrugated cardboard packaging box, comprising an inner box and an outer box, wherein the inner box is fixedly connected to the inside of the outer box, the inner box comprises a long board and a short board, a supporting cardboard is movably connected to the inner side of the long board, a snap-fit ​​strip is fixedly connected to the inner side of the short board, and one end of the supporting cardboard is snap-fit ​​connected to one side of the snap-fit ​​strip.

[0007] Preferably, a cavity is provided between the inner box and the outer box, and multiple horizontal strips are provided inside the cavity.

[0008] Preferably, the multiple horizontal bars are fixedly connected between the inner box and the outer box, and the multiple horizontal bars form a "well" shaped structure.

[0009] Preferably, the supporting cardboard, long board, and short board form a triangular structure.

[0010] Preferably, one side of the snap-fit ​​strip is machined with a bevel, and the snap-fit ​​connection of the supporting cardboard is inside the bevel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When in use, this utility model achieves double-layer protection by setting an inner box and an outer box. When a collision occurs during transportation, the outer box will be squeezed and deformed. Because there is a cavity between the inner box and the outer box, the outer box has a certain buffer space. The double-layer design of the inner box and the outer box can play a shock absorption role. Since the supporting cardboard, long board and short board form a triangular structure, the surrounding structure of the inner box is more solid and the pressure resistance is more ideal.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] Example 1: Please refer to Figure 1 - Figure 2 This embodiment of a pressure-resistant and shockproof corrugated cardboard packaging box includes an inner box 1 and an outer box 2. The inner box 1 is fixedly connected to the inside of the outer box 2. The inner box 1 includes a long plate 6 and a short plate 7. The inner side of the long plate 6 is movably connected to a supporting cardboard 3. The inner side of the short plate 7 is fixedly connected to a snap-fit ​​strip 4. One end of the supporting cardboard 3 is snap-fit ​​connected to one side of the snap-fit ​​strip 4.

[0018] The inner box 1 and the outer box 2 are designed to provide double protection for the objects inside the outer box 2. When a collision occurs during transportation, the double-layer design of the inner box 1 and the outer box 2 can provide shock absorption.

[0019] Furthermore, a cavity is provided between the inner box 1 and the outer box 2, and multiple horizontal bars 5 are provided inside the cavity. The multiple horizontal bars 5 are fixedly connected between the inner box 1 and the outer box 2. The cavity between the inner box 1 and the outer box 2 provides a certain buffer space when the outer box 2 is squeezed and deformed. The "well" shaped structure formed by the multiple horizontal bars 5 makes the connection between the inner box 1 and the outer box 2 more secure and can better play the role of pressure resistance and shock absorption.

[0020] Furthermore, one side of the snap-fit ​​strip 4 is machined with a beveled cut, and the snap-fit ​​connection of the support cardboard 3 is inside the beveled cut. By rotating the support cardboard 3, one end of the support cardboard 3 moves closer to the short board 7 around the inside of the long board 6, so that one end of the support cardboard 3 is inserted into the beveled cut on one side of the snap-fit ​​strip 4, thereby forming a triangular structure with the support cardboard 3, the long board 6 and the short board 7, making the structure of the inner box 1 more robust and the pressure resistance more ideal.

[0021] Working principle: By setting up an inner box 1 and an outer box 2, a double-layer protection effect can be achieved. When a collision occurs during transportation, the outer box 2 will be squeezed and deformed. Since there is a cavity between the inner box 1 and the outer box 2, the outer box 2 has a certain buffer space. The double-layer design of the inner box 1 and the outer box 2 can play a shock absorption role. Since the supporting cardboard 3, long board 6 and short board 7 form a triangular structure, the surrounding structure of the inner box 1 is more solid and the pressure resistance is more ideal.

[0022] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
