Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box technology, and in particular to a pressure-resistant pearl cotton honeycomb structure packaging box. Background Technology
[0002] In the field of modern logistics and packaging, pressure-resistant EPE foam honeycomb structure packaging boxes are widely used for the transportation and storage of electronic products, precision instruments, fragile goods, and other items due to their excellent cushioning performance and environmentally friendly characteristics. The honeycomb closed-cell structure of EPE foam gives it excellent energy absorption capabilities, effectively reducing damage to goods caused by vibration and collisions during transportation. However, with the increasing complexity of the logistics and transportation environment and the rising demands for cargo load-bearing capacity, the limitations of traditional packaging boxes in terms of structural stability and protective performance are gradually becoming apparent.
[0003] In existing technologies, common EPE foam honeycomb structure packaging boxes mostly rely on the material's own cushioning properties, improving the protective effect by increasing the thickness of the EPE foam or adjusting the honeycomb pore size. Their mechanical structure design is relatively simple, often using a simple box body and lid splicing method, with no additional external support for the box body, and the lid and box body are only fixed together by buckles, tape or simple magnetic attraction.
[0004] However, when existing packaging boxes are stacked or subjected to strong pressure, the bottom and corners are prone to deformation and damage due to stress concentration, resulting in damage to the goods inside the box. To address this issue, a pressure-resistant pearl cotton honeycomb structure packaging box is proposed. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a pressure-resistant pearl cotton honeycomb structure packaging box, which aims to improve the problem that in the prior art, the bottom and corner parts of the packaging box are easily deformed and damaged due to stress concentration when stacked or subjected to strong compression, resulting in damage to the goods inside the box.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The reinforcement component includes a bracket, which is sleeved on the outside of the box. A fixing sleeve is fixedly connected to the side wall of the bracket. A connecting plate is rotatably connected inside the fixing sleeve. A base is fixedly connected to the bottom of the bracket. A protective pad is fixedly connected to the inner wall of the bracket. The side wall of the protective pad is attached to the side wall of the box.
[0009] As a further description of the above technical solution:
[0010] The fixing component includes magnetic block one and magnetic block two. One side wall of magnetic block one is fixedly connected to the inside of the box, and the side wall of magnetic block two is fixedly connected to the inside of the cover plate.

[0015] As a further description of the above technical solution:
[0016] The side wall of the box is fixedly connected to an installation sleeve, and a rotating plate is rotatably connected inside the installation sleeve.
[0017] As a further description of the above technical solution:
[0018] The rotating plate is L-shaped and is distributed on the left and right sides of the box.

The connecting plates inside the fixing sleeve of the bracket side wall are rotatably connected in an inclined cross shape and surround the box body. This can convert the pressure and impact force into axial tension and compression, improve the protection effect of the packaging box, and solve the problem that some pressure-resistant pearl cotton honeycomb structure packaging boxes are prone to deformation and damage at the bottom and corners due to stress concentration when stacked or subjected to strong compression, resulting in damage to the goods inside the box. The above structure enhances the strength of the packaging box.
[0025] 2. In this utility model, when the cover slides onto the upper surface of the box, magnetic block one and magnetic block two attract each other to prevent the cover from being accidentally opened during transportation, and also to prevent dust, moisture, etc. from entering the box. In addition, after the cover is closed, the rotating plate is rotated to lock into the cover, and together with magnetic block one and magnetic block two, the cover is firmly fixed to the box.

[0033] 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.
[0034] Reference Figures 1-3 An embodiment of this utility model is provided: a pressure-resistant pearl cotton honeycomb structure packaging box, including a box body 1, a cover plate 2 slidably connected to the upper surface of the box body 1, an inner lining 3 provided inside the box body 1, a reinforcing component provided on the side wall of the box body 1, and a fixing component provided on the side wall of the box body 1.
[0035] The reinforcement components include a bracket 4, which is fitted onto the outside of the box 1 to form an external rigid support frame. This effectively distributes the pressure on the box 1, preventing deformation due to excessive force. A fixing sleeve 5 is fixedly connected to the side wall of the bracket 4. A connecting plate 6 is rotatably connected inside the fixing sleeve 5. The connecting plates 6 are arranged in an inclined, cross-shaped pattern and surround the box 1, converting pressure and impact into axial tensile and compressive forces. This force is then transmitted and dispersed through the bracket 4, greatly enhancing the overall pressure resistance of the packaging box and preventing damage caused by localized stress concentration. A base 7 is fixedly connected to the bottom of the bracket 4, providing stable support for the entire packaging box and preventing deformation of the bottom when bearing heavy loads, ensuring stable placement. A protective pad 8 is fixedly connected to the inner wall of the bracket 4. The protective pad 8 is made of rubber, a highly elastic material, which buffers friction and impact between objects, protecting the packaging box from damage. The pad 8 is used to adhere to the side wall of the box 1, acting as a buffer against friction between the support 4 and the box 1, preventing damage to the corners of the box 1 under the action of the support 4, and absorbing external impact. It effectively assists the box 1 and the inner liner 3 in protecting the items inside the box. The box 1 is made of pearl cotton, which is a material with good cushioning performance and flexibility, and its function is to absorb external impact. The inner liner 3 has a honeycomb structure inside. This honeycomb structure is used to disperse and buffer energy through the deformation of millions of independent airbags, providing basic cushioning protection for the items inside the box and reducing the impact of external impact on the items inside the box. The box 1 and the inner liner 3 work together to absorb and disperse the impact when subjected to external collisions or compression, thereby enhancing the protection of the items inside the box. The support 4, fixing sleeve 5, connecting plate 6, base 7 and protective pad 8 form a reinforcement component, which, together with the box 1 and the inner liner 3, significantly improves the pressure resistance of the packaging box and provides all-round protection for the items inside the box.
[0036] Reference Figures 3-5The fixing components include magnetic block 9 and magnetic block 10. Magnetic block 9 is fixedly connected to the inside of the box body 1, and magnetic block 10 is fixedly connected to the inside of the cover plate 2. Magnetic block 9 and magnetic block 10 attract each other, generating magnetic force through their own magnetism to tightly connect the cover plate 2 to the box body 1. This allows for quick and convenient initial fixing of the cover plate 2 to the box body 1, effectively preventing the cover plate 2 from accidentally opening due to slight shaking during transportation. It also provides a certain degree of sealing for the packaging box, preventing dust, moisture, and other external impurities from entering the box and protecting the contents from external environmental influences. The wall is fixedly connected to an installation sleeve 11, and a rotating plate 12 is rotatably connected inside the installation sleeve 11. The rotating plate 12 is L-shaped and distributed on the left and right sides of the box body 1. The side wall of the rotating plate 12 is slidably connected to the inside of the box body 1 and the side wall of the rotating plate 12 is slidably connected to the inside of the cover plate 2. The rotating plate 12 is used to manually rotate after the cover plate 2 is closed on the upper surface of the box body 1, so that one end of its L-shaped structure is inserted into the inside of the cover plate 2, forming a stable mechanical connection with the inside of the box body 1. This further enhances the connection stability between the cover plate 2 and the box body 1, effectively resists large external vibrations, collisions and other forces, and ensures that the cover plate 2 will not easily detach from the box body 1, providing a more reliable protection for the items inside the box.
[0037] Working Principle: The box body 1 is made of pearl cotton, which has good cushioning performance and flexibility. It can undergo elastic deformation when subjected to external impact, absorbing part of the impact force. The inner lining 3 has a honeycomb structure inside, which can effectively disperse the impact force. The deformation of millions of independent airbags buffers the energy, providing basic cushioning protection for the items inside the box. When the packaging box is subjected to external collision or compression, the box body 1 and the inner lining 3 work together to disperse and absorb the impact force, reducing the impact on the items inside the box. The bracket 4 is fitted on the outside of the box body 1, forming an external rigid support frame. The base 7 at the bottom of the bracket 4 contacts the ground, providing support for the entire box. The packaging box provides stable support to prevent deformation under pressure. The connecting plates 6, which are rotatably connected inside the fixing sleeves 5 on the side walls of the bracket 4, are inclined and cross-shaped, surrounding the box body 1. This inclined and cross-shaped structure is similar to a truss, which can convert the pressure and impact force into axial tensile and compressive forces. These forces are conducted and dispersed through the connecting plates 6 and the bracket 4, greatly enhancing the overall pressure resistance of the packaging box. For example, when the packaging box is subjected to vertical pressure, the connecting plates 6 and the bracket 4 distribute the pressure in all directions, avoiding local stress concentration that could damage the box body 1. At the same time, the protective pads 8 fixedly connected to the inner wall of the bracket 4 are made of rubber, and their side walls are attached to the box body. 1. The side wall and protective pad 8 serve two purposes: firstly, they cushion the friction between the support 4 and the box body 1, preventing damage to the edges and corners of the box body 1 from the support 4; secondly, the rubber protective pad 8 itself has a certain degree of elasticity, further absorbing external impact and assisting the box body 1 and inner lining 3 in protecting the items inside. Magnetic block one 9 is fixedly connected to the inside of the box body 1, and magnetic block two 10 is fixedly connected to the inside of the cover plate 2. Magnetic block one 9 and magnetic block two 10 attract each other. When the cover plate 2 slides onto the upper surface of the box body 1, magnetic block one 9 and magnetic block two 10 attract each other, and the resulting magnetic force tightly connects the cover plate 2 and the box body 1 together. To prevent the cover 2 from opening accidentally during transportation, it also provides a certain degree of sealing for the packaging box, preventing dust and moisture from entering the box. In addition, the rotating plate 12 further enhances the connection stability between the cover 2 and the box body 1. The rotating plate 12 is L-shaped and distributed on the left and right sides of the box body 1. Its side walls can slide to connect the inside of the box body 1 and the inside of the cover 2. After the cover 2 is closed, rotating the rotating plate 12 will cause it to snap into the inside of the cover 2. Together with the magnetic block 9 and the magnetic block 10, the cover 2 is firmly fixed to the box body 1. Even when subjected to severe vibration or collision, the cover 2 will not easily detach from the box body 1, ensuring the safety of the items inside the box.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
