Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a high-strength shock-absorbing corrugated cardboard box. Background Technique

[0002] A corrugated cardboard box is a rigid paper box made from corrugated cardboard through processes such as die-cutting, indentation, box nailing, or gluing. It is mainly composed of corrugated base paper and linerboard, and the linerboard can be further divided into kraft paperboard and imitation kraft paperboard, etc.

[0003] The corrugated cardboard has a special structure, with 60 - 70% of its volume being empty in the cardboard structure. Therefore, it has good shock-absorbing performance, can prevent the packaged items from being collided and impacted, is lightweight and firm. The corrugated cardboard is a hollow structure, using the least amount of materials to form a box body with relatively high rigidity. Therefore, it is more firm than similar cardboard boxes, and compared with wooden boxes of the same volume, its weight is only about half of that of wooden boxes.

[0004] However, the compressive strength of the existing corrugated cardboard boxes in the prior art is affected by pressure to a certain extent. An increase in pressure will cause the compressive strength of the cardboard box to decrease, and when the cardboard box is subjected to a large impact force, its shock-absorbing effect is limited, and it is difficult to effectively protect the internal items from being damaged. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a high-strength shock-absorbing corrugated cardboard box to solve the technical problems that the compressive strength of the existing corrugated cardboard boxes in the prior art is affected by pressure to a certain extent, an increase in pressure will cause the compressive strength of the cardboard box to decrease, and when the cardboard box is subjected to a large impact force, its shock-absorbing effect is limited, and it is difficult to effectively protect the internal items from being damaged.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A high-strength shock-absorbing corrugated cardboard box, including a box body, in which a first support plate and a second support plate are symmetrically arranged. The included angle between the first support plate and the second support plate is 90°. A reinforcing block is arranged at the included angle between the first support plate and the second support plate. A plurality of first connecting rods are fixedly connected inside the first support plate, and a first fixing block is fixedly connected to the end of the first connecting rod. A plurality of second connecting rods are fixedly installed inside the second support plate, and a second fixing block is fixedly connected to the end of the second connecting rod. A first airbag is arranged inside the first fixing block, a first pressing plate is arranged outside the first airbag, a second airbag is fixedly connected to the inner side of the second fixing block, and a second pressing plate is arranged outside the second airbag.

[0007] By adopting the above technical solution, during use, the first support plate and the second support plate are clamped inside the box body. Then, through the 90° angle design between the first support plate and the second support plate, a stable support structure is provided for the box body, which can resist forces from different directions and maintain the overall stability of the box body. The reinforcing blocks located at the angle can further enhance the connection strength of the support plates and prevent deformation or damage caused by uneven stress. At the same time, the first airbag and the second airbag are respectively arranged in the first fixing block and the second fixing block, and they are combined with the first pressing plate and the second pressing plate on the outside to form an effective shock absorption and buffering system. When the box body is impacted or vibrated, the airbags can absorb and disperse energy, reduce the direct impact on the items inside the box, and protect the items from damage. The first fixing block and the second fixing block are respectively fixed on the first support plate and the second support plate through the first connecting rod and the second connecting rod. With this structure, the replacement and maintenance of the entire shock absorption component become more convenient. At the same time, the flexibility of the box body design is also increased, thereby improving the shock absorption and compressive resistance of the entire high-strength shock-absorbing corrugated cardboard box.

[0008] The present utility model is further configured such that convex blocks are fixedly connected to the outer sides of the reinforcing blocks, and sliding grooves for cooperating with the convex blocks are respectively formed on the inner sides of the first support plates.

[0009] By adopting the above technical solution, the mutual cooperation between the provided convex blocks and the sliding grooves is conducive to fixing the reinforcing blocks on the inner sides of the first support plates.

[0010] The present utility model is further configured such that the reinforcing blocks are located on both sides of the first support plate and at the angle between the first support plate and the second support plate. The reinforcing blocks are of a right triangle structure and are formed by folding corrugated paper.

[0011] By adopting the above technical solution, when the provided reinforcing blocks are of a right triangle structure, it is conducive to better clamping at the angle between the first support plate and the second support plate. Through the characteristics of the right triangle itself, it can effectively resist the lateral pushing force and shear force of external forces, thereby enhancing the stability and load-bearing capacity of the entire support structure, preventing deformation or damage caused by uneven stress, and improving the strength of the entire corrugated cardboard box.

[0012] The present utility model is further configured such that a first air nozzle for cooperating with the first airbag is fixedly connected to the outer side of the first fixing block, and a second air nozzle for cooperating with the second airbag is fixedly connected to the outer side of the second fixing block.

[0013] By adopting the above technical solutions, through the first air nozzle and the second air nozzle, the first airbag and the second airbag can be conveniently inflated. When needed, only by connecting the air source to the air nozzle, the inflation process can be quickly completed, improving work efficiency. At the same time, when deflation is required, the operation can also be carried out through the air nozzle, which helps to ensure that the airbag is in a safe and controllable state when maintaining, replacing or adjusting the airbag. Moreover, through the first air nozzle and the second air nozzle, the inflation amount of the airbag can be adjusted according to actual needs, so as to change the shape, size or hardness of the airbag, so that the entire corrugated cardboard box can better adapt to different working environments and requirements.

[0014] The utility model is further arranged such that chamfers are provided inside both the first support plate and the second support plate. The first connecting rod is fixed between the chamfer and the first fixing block, and the second connecting rod is fixed between the chamfer and the second fixing block.

[0015] By adopting the above technical solutions, the designed chamfers help to disperse stress at the connection points. When the connecting rod is subjected to external forces, the chamfers can evenly disperse these forces to a wider area of the support plate, thereby avoiding excessive stress concentration at the connection points and reducing the risk of structural damage. The design of the chamfers can make the edges of the support plate smoother and more aesthetically pleasing.

[0016] The utility model is further arranged such that both the first fixing block and the second fixing block are circular structures, and both the first fixing block and the second fixing block are made of plastic materials.

[0017] By adopting the above technical solutions, when both the first fixing block and the second fixing block are circular structures, they can cooperate with the first connecting rod and the second connecting rod to achieve a better supporting effect. When the box body is subjected to external pressure or impact force, the circular structures can evenly disperse the force to the entire structure, thereby reducing the risk of single-point stress and improving the stability and durability of the structure. When the first fixing block and the second fixing block are made of plastic materials, it helps to reduce the overall weight of the box body structure, lower the transportation and installation costs, and improve the compressive strength of the entire corrugated cardboard box.

[0018] The utility model is further arranged such that slots are provided on both sides of the box body, and kraft paper structures are provided on the inner sides of both the first support plate and the second support plate.

[0019] By adopting the above technical solutions, the provided slots are beneficial for handling and moving the box body, and the kraft paper structures on the outer sides of the first support plate and the second support plate can effectively enhance the overall stability effect of the first support plate and the second support plate after being processed, so as to prevent deformation or damage during use. Moreover, due to the fact that kraft paper itself has certain sound insulation and shock absorption properties, it can reduce a certain amount of noise and also achieve the effect of shock absorption and protection.

[0020] In summary, the present utility model mainly has the following beneficial effects:

[0021] 1. In the present utility model, the first support plate and the second support plate are clamped inside the box body, and then through the 90° included angle design between the first support plate and the second support plate, a stable support structure is provided for the box body, which can resist forces from different directions and maintain the overall stability of the box body. The reinforcing blocks located at the included angle can further enhance the connection strength of the support plates and prevent deformation or damage caused by uneven stress. At the same time, the first airbag and the second airbag are respectively arranged in the first fixing block and the second fixing block, and they are combined with the first pressing plate and the second pressing plate on the outside to form an effective shock absorption and buffering system. When the box body is impacted or vibrated, the airbags can absorb and disperse energy, reduce the direct impact on the items inside the box, and protect the items from damage. The first fixing block and the second fixing block are respectively fixed on the first support plate and the second support plate through the first connecting rod and the second connecting rod. With this structure, the replacement and maintenance of the entire shock absorption component become more convenient. At the same time, the flexibility of the box body design is also increased, thereby improving the shock absorption and compressive resistance of the entire high-strength shock-absorbing corrugated cardboard box;

[0022] 2. When the reinforcing block provided in the present utility model is in a right triangle structure, it is beneficial to better be clamped at the included angle between the first support plate and the second support plate.

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0029] The embodiments of the present utility model will be described below according to its overall structure.

[0030] A high-strength shock-absorbing corrugated cardboard box, as Figures 1-4 shown, includes a box body 1. A first support plate 3 and a second support plate 4 are symmetrically arranged inside the box body 1. The included angle between the first support plate 3 and the second support plate 4 is 90°. A reinforcing block 5 is arranged at the included angle between the first support plate 3 and the second support plate 4. A plurality of first connecting rods 8 are fixedly connected inside the first support plate 3. The end of the first connecting rod 8 is fixedly connected with a first fixing block 6. A plurality of second connecting rods 18 are fixedly installed inside the second support plate 4. The end of the second connecting rod 18 is fixedly connected with a second fixing block 17. A first airbag 13 is arranged inside the first fixing block 6. A first pressing plate 9 is arranged outside the first airbag 13. A second airbag 14 is fixedly connected to the inner side of the second fixing block 17. A second pressing plate 11 is arranged outside the second airbag 14.

[0031] During use, the first support plate 3 and the second support plate 4 are clamped inside the box body 1. Then, through the 90° included angle design between the first support plate 3 and the second support plate 4, a stable support structure is provided for the box body 1, which can resist forces from different directions and maintain the overall stability of the box body 1. The reinforcing block 5 located at the included angle can further enhance the connection strength of the support plates and prevent deformation or damage caused by uneven stress. At the same time, the first airbag 13 and the second airbag 14 are respectively arranged inside the first fixing block 6 and the second fixing block 17. They are combined with the first pressing plate 9 and the second pressing plate 11 outside to form an effective shock-absorbing and buffering system. When the box body 1 is impacted or vibrated, the airbags can absorb and disperse energy, reduce the direct impact on the items inside the box, and protect the items from damage. The first fixing block 6 and the second fixing block 17 are respectively fixed on the first support plate 3 and the second support plate 4 through the first connecting rods 8 and the second connecting rods 18. With this structure, the replacement and maintenance of the entire shock-absorbing component become more convenient. At the same time, the flexibility of the design of the box body 1 is also increased, thereby improving the shock-absorbing and compressive properties of the entire high-strength shock-absorbing corrugated cardboard box.

[0032] The further cooperation between the convex block 12 and the chute 16 is conducive to fixing the reinforcing block 5 inside the first support plate 3. When the reinforcing block 5 is set in a right-angled triangle structure, it is conducive to better clamping at the included angle between the first support plate 3 and the second support plate 4. Through the characteristics of the right-angled triangle itself, it can effectively resist the lateral pushing force and shear force of external forces, thereby enhancing the stability and bearing capacity of the entire support structure, preventing deformation or damage caused by uneven stress, and improving the strength of the entire corrugated cardboard box. Through the first air nozzle 7 and the second air nozzle 10, the first airbag 13 and the second airbag 14 can be inflated conveniently. When needed, only connect the air source to the air nozzle, and the inflation process can be quickly completed, improving work efficiency. At the same time, when deflation is required, it can also be operated through the air nozzle, which helps to ensure that the airbag is in a safe and controllable state when maintaining, replacing or adjusting the airbag. Moreover, through the first air nozzle 7 and the second air nozzle 10, the inflation amount of the airbag can be adjusted according to actual needs, thereby changing the shape, size or hardness of the airbag, so that the entire corrugated cardboard box can better adapt to different working environments and requirements.

[0033] In this embodiment, the design of the chamfer 15 helps to disperse stress at the connection. When the connecting rod is subjected to external forces, the chamfer 15 can evenly disperse these forces to a wider area of the support plate, thus avoiding excessive stress concentration at the connection point and reducing the risk of structural damage. The design of the chamfer 15 can make the edge of the support plate smoother and more beautiful. When the first fixing block 6 and the second fixing block 17 are both circular structures, they can cooperate with the first connecting rod 8 and the second connecting rod 18 to achieve a better supporting effect. When the box body 1 is subjected to external pressure or impact force, the circular structure can evenly disperse the force to the entire structure, thereby reducing the risk of single-point stress and improving the stability and durability of the structure. When the first fixing block 6 and the second fixing block 17 are made of plastic material, it helps to reduce the overall weight of the box body 1, reduce transportation and installation costs, and improve the compressive strength of the entire corrugated cardboard box. Finally, the provided slot 2 is conducive to handling and moving the box body 1, and the kraft paper structure on the outer sides of the first support plate 3 and the second support plate 4 can effectively enhance the overall stability effect of the first support plate 3 and the second support plate 4 after being processed, so as to prevent deformation or damage during use. Moreover, due to the sound insulation and shock absorption performance of the kraft paper itself, it can reduce a certain amount of noise and achieve the effect of shock absorption and protection.

[0034] Although embodiments of the present utility model have been shown and described, the specific embodiments are merely explanations of the present utility model and are not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
