Description

Technical Field

[0001] This utility model relates to the field of cardboard boxes, specifically a cardboard box with a shock-absorbing and cushioning structure. Background Technology

[0002] Cardboard boxes are three-dimensional in shape and have the advantages of low cost, light weight, and recyclability. Each cardboard box is composed of multiple cardboard pieces. The raw material for making cardboard boxes is pulp, mostly corrugated paper. Because corrugated paper itself is a recyclable material, discarded cardboard boxes can be recycled and reused, effectively protecting the environment. Existing cardboard box packaging is mostly used for: logistics distribution, industrial packaging, food packaging, pharmaceuticals, and the distribution and packaging of electronic products. Cardboard boxes are mainly composed of bottom cardboard, side cardboard, and top cardboard. The outer surface of the cardboard box packaging can display product information, facilitate user handling, and has good transportation performance.

[0003] However, existing cardboard boxes still have the following drawbacks in use: Traditional cardboard boxes are mostly made of single or double-layered ordinary cardboard, which is mainly made from wood pulp. While these cardboards have a certain degree of flexibility, their cushioning and energy absorption capacity is limited when subjected to impact. For example, common kraft paperboard is prone to cracking or deformation when faced with impact, failing to effectively protect the contents. Furthermore, ordinary cardboard has a low modulus of elasticity, failing to quickly disperse impact force, causing the impact to concentrate in a localized area, increasing the risk of damage to the contents. Existing cardboard boxes rely solely on the cardboard's own toughness to resist impacts, which cannot provide sufficient cushioning when encountering large impacts, easily causing damage to the contents. For example, during transportation, cardboard boxes may be subjected to collisions from other goods, and the boxes are unable to effectively withstand such impacts. The four corners and edges of traditional cardboard boxes are easily damaged upon impact because these areas are stress concentration zones and lack effective protection. For example, during handling, the corners of the cardboard box are easily collided with other objects; due to the lack of anti-collision structures, the cardboard at the corners is prone to cracking, thus affecting the overall protective performance of the cardboard box. To reduce costs, some cardboard boxes use thinner or lower-quality cardboard, resulting in lower bending and compressive strength. When subjected to a certain weight of stacked goods or external pressure, this cardboard is prone to deformation and collapse, causing the box to lose its protective function for the contents. For example, during warehouse storage, when multiple layers of boxes are stacked together, the thinner cardboard cannot withstand the weight of the boxes on top and is easily crushed. Existing cardboard boxes often lack effective reinforcing structures to enhance their compressive strength. The absence of reinforcing ribs or plates means that the box cannot effectively distribute stress under pressure, making it prone to deformation in localized areas. For example, without reinforcement at the bottom and top, these areas are prone to denting under pressure from goods above, affecting the box's stability. Therefore, existing cardboard boxes suffer from poor impact resistance and susceptibility to deformation, exhibiting poor resistance to deformation. Further improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a cardboard box with a shock-absorbing structure, which can effectively solve the technical problems of poor anti-collision performance, easy deformation, and poor resistance to deformation of existing cardboard boxes.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a cardboard box with a shock-absorbing structure, including a box body and a detachable top cover. A fixed frame is provided on the surface of the box body. Several anti-collision strips are provided on the surface of the box body near the fixed frame. The anti-collision strips are arranged along the fixed frame. Several anti-collision plates are provided on the surface of the box body. The anti-collision plates, anti-collision strips and fixed frame are all on the same horizontal plane. The anti-collision plates include two layers of corrugated cardboard and honeycomb cardboard. The honeycomb cardboard is disposed between the two corrugated cardboards. Several rigid plates are also provided between the honeycomb cardboard and the corrugated cardboard. The rigid plates are arranged at equal intervals. Side plates are provided between the honeycomb cardboard and the corrugated cardboard. Several support plates with a triangular structure are also provided between the honeycomb cardboard and the corrugated cardboard. The support plates are arranged at equal intervals.

[0006] Furthermore, the interior of the housing is fitted with a reinforcing box composed of five protective plates. A support base is bonded to the inside of the reinforcing box. Four reinforcing plates are also provided at one end of the support base. The four reinforcing plates are arranged along the inner wall of the reinforcing box. A foam board is also provided at one end of each reinforcing plate. Columns are also provided at the four corners of the reinforcing box. The sides of the columns are connected to the support base, the reinforcing plates, and the foam boards.

[0007] Furthermore, a sponge board is placed inside the reinforcing box, and the side of the sponge board is tightly fitted to the inner wall of the foam board.

[0008] Furthermore, the surfaces of the housing, top cover, fixing frame, and anti-collision plate are all covered with a polypropylene film.

[0009] Furthermore, one end of the top cover is provided with two round holes, through which hemp ropes are threaded.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a cardboard box with a shock-absorbing structure. By setting anti-collision plates, anti-collision strips and fixing frames on the surface of the box and placing them on the same horizontal plane, a sturdy protective structure is formed. The anti-collision plates are composed of two layers of corrugated cardboard and honeycomb cardboard, with a rigid plate and a triangular support plate sandwiched in the middle. This effectively disperses and absorbs the impact force, preventing the cardboard box from deforming due to collision or squeezing during transportation, and greatly improving the anti-collision performance and deformation resistance of the cardboard box.

Detailed Implementation

[0016] 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.

[0017] The following is combined Figures 1-3 A detailed description of a cardboard box with a shock-absorbing and cushioning structure according to this utility model is provided below:

[0018] A cardboard box with a shock-absorbing structure includes a box body 1 and a detachable top cover 2. A fixing frame 6 is provided on the surface of the box body 1. Several anti-collision strips 7 are provided on one end of the surface of the box body 1 near the fixing frame 6. The anti-collision strips 7 are arranged along the fixing frame 6. Several anti-collision plates 5 are provided on the surface of the box body 1. The anti-collision plates 5, anti-collision strips 7 and fixing frame 6 are all on the same horizontal plane. The anti-collision plate 5 includes two layers of corrugated cardboard 15 and honeycomb cardboard 16. The honeycomb cardboard 16 is disposed between the two corrugated cardboard 15. Several rigid plates 18 are also provided between the honeycomb cardboard 16 and the corrugated cardboard 15. The rigid plates 18 are all equidistantly distributed. Side plates 17 are provided between the honeycomb cardboard 16 and the corrugated cardboard 15. Several triangular support plates 19 are also provided between the honeycomb cardboard 16 and the corrugated cardboard 15. The support plates 19 are all equidistantly distributed.

[0019] The box 1 is fitted with a reinforced box 9 consisting of five protective plates 8. A support base 11 is glued to the inside of the reinforced box 9. Four reinforcing plates 12 are also provided at one end of the support base 11. The four reinforcing plates 12 are arranged along the inner wall of the reinforced box 9. A foam board 10 is also provided at one end of the reinforcing plate 12. Columns 13 are also provided at the four corners of the reinforced box 9. The sides of the columns 13 are connected to the support base 11, the reinforcing plates 12 and the foam board 10. A sponge board 14 is also placed inside the reinforced box 9. The sides of the sponge board 14 are tightly attached to the inner wall of the foam board 10. The surfaces of the box 1, the top cover 2, the fixing frame 6 and the anti-collision plate 5 are all covered with a polypropylene film. Two round holes 3 are provided at one end of the top cover 2. Hemp ropes 4 are threaded through the two round holes 3.

[0020] In this embodiment, the reinforced box 9 inside the carton 1 consists of five protective plates 8, with an internally bonded support base 11, reinforced plates 12 and foam boards 10 arranged around it, and uprights 13 at the corners. This significantly enhances the internal support strength of the carton, ensuring the stability of the contents during transportation and handling, and preventing damage caused by vibration or impact. The support base 11 provides basic support, the reinforced plates 12 enhance the structural strength of the reinforced box 9, the foam boards 10 have good cushioning performance and can absorb vibration, and the uprights 13 further stabilize the entire reinforced box 9 structure, providing better protection for the items placed inside and reducing damage caused by vibration and collision. The rigid plate 18 between the honeycomb cardboard 16 and the corrugated cardboard 15 in the anti-collision plate 5 enhances the overall strength of the anti-collision plate 5, making it less prone to deformation when impacted. The equidistantly arranged triangular support plates 19 utilize the stability principle of triangles to further improve the compression resistance and cushioning capacity of the anti-collision plate 5, effectively dispersing impact force and preventing concentrated impact force from damaging the carton. The sponge board 14 and foam board 10 inside the reinforced box 9 are tightly bonded together, further improving cushioning performance, especially for fragile items, providing all-around protection and reducing the risk of shaking and collisions during transportation. The sponge board 14 has good flexibility and energy absorption properties, working together with the foam board 10 to provide multi-layered cushioning protection for the internal items. During transportation, vibrations and impacts from both the lateral and longitudinal directions are effectively absorbed and cushioned by the sponge board 14 and foam board 10, further ensuring the safety of the items. The polypropylene film on the surfaces of the box body 1, top cover 2, fixing frame 6, and anti-collision plate 5 not only provides moisture and water protection, protecting the internal items from humid environments, but also increases surface abrasion resistance, reducing damage to the box caused by friction during transportation and handling, and extending the box's lifespan. Two round holes 3 on the top cover 2 allow for the insertion of hemp rope 4, facilitating manual lifting of the top cover 2 and opening of the box body 1.

[0021] This embodiment of a cardboard box with a shock-absorbing structure forms a robust protective structure by setting anti-collision plates 5, anti-collision strips 7, and fixing frames 6 on the surface of the box body 1, all on the same horizontal plane. The anti-collision plates 5 are composed of two layers of corrugated cardboard 15 and honeycomb cardboard 16, with a rigid plate 18 and a triangular support plate 19 sandwiched in the middle, effectively dispersing and absorbing impact forces, preventing the cardboard box from deforming due to collision or squeezing during transportation, and greatly improving the anti-collision performance and deformation resistance of the cardboard box.
