Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box with pressure resistance function. Background Technology

[0002] Packaging boxes are widely used containers for storing and transporting goods, providing basic protection and convenient handling. Especially during logistics, warehousing, and distribution, packaging boxes need to withstand various pressures from stacking, handling, and external compression. If the packaging box's pressure resistance is insufficient, it may deform or collapse during transportation or storage, leading to damage to the contents and consequently economic losses or reduced logistics efficiency. Therefore, designing packaging boxes with excellent pressure resistance is an important requirement to ensure the safety of goods and the lifespan of the packaging boxes.

[0003] Currently, cardboard boxes are the primary form of packaging, widely used for the storage and transportation of goods. Existing cardboard boxes typically enhance their compression resistance by adjusting the structure of the corrugated cardboard (such as U-shaped, V-shaped, or UV-hybrid) and the cardboard thickness. Some designs also add simple support structures inside the box to improve strength. However, these designs mainly focus on enhancing the overall compression resistance of the box, offering limited protection for the lid and corners. Especially during transportation and handling, the corners of the box and lid are easily subjected to external impacts, leading to localized deformation or damage, thus affecting the overall structural strength of the box and the safety of the contents. Therefore, a packaging box with compression resistance is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a packaging box with pressure resistance, aiming to improve the limited protection of the box lid and corners of the box body in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pressure-resistant packaging box includes a box body, a box cover on the top of the box body, a reinforcing component inside the box body, and a cushioning component inside the box body.

[0007] The reinforcement components include a base pad, which is fixedly connected to the inside of the box. An inner corner protector is fixedly connected to the top of the base pad. A reinforcement plate is fixedly connected to the top of the inner corner protector. A limit plate frame is fixedly connected between the reinforcement plates. A bottom plate is fixedly connected to the bottom of the box. A clamping plate is fixedly connected to the side wall of the box. Outer corner protectors are fixedly connected to the four corners of the side wall of the box cover.

[0008] As a further description of the above technical solution:

[0009] The buffer assembly includes a corrugated plate and a spring strip. The corrugated plate is fixedly connected to the top of the base pad, and the spring strip is fixedly connected to the side wall of the limiting plate frame.

[0010] As a further description of the above technical solution:

[0011] A pad is fixedly connected to the top of the first corrugated plate, a second corrugated plate is fixedly connected to the top of the pad, and a placement plate is fixedly connected to the top of the second corrugated plate.

[0012] As a further description of the above technical solution:

[0013] Each of the spring bars has a contact plate fixedly connected to its opposite side;

[0014] As a further description of the above technical solution:

[0015] The lid is slidably connected to the side wall of the box body, and the side wall of the lid is slidably connected to the inside of the card plate;

[0016] As a further description of the above technical solution:

[0017] The inner corner protectors are located at the four corners inside the box, and the reinforcing plates are located at the edges inside the box.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the outer corner guards at the four corners of the box cover provide edge and corner protection for the box cover, which can effectively resist external impacts during transportation and handling, and extend the service life of the box cover. The reinforcing plates and inner corner guards are arranged at the four corners and edges inside the box, which not only enhances the overall structural strength and pressure resistance of the box, but also reduces the risk of deformation caused by external impacts, thereby providing a safer protection and storage environment for the internal items.

[0020] 2. In this utility model, the corrugated plate absorbs external impact force through its corrugated structure, effectively reducing the damage to the internal items. The pad and placement plate provide a stable surface for placing items, while dispersing the impact force to the corrugated structure, significantly improving the cushioning performance. The spring strip deforms under impact, and the cushioning force is evenly dispersed through the contact plate, playing a role in protecting the items, thereby improving the impact resistance and ensuring the safety of the items.

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.

[0028] Reference Figures 1-3 This utility model provides an embodiment of a packaging box with pressure resistance, comprising a box body 1, a box cover 2 on the top of the box body 1, a reinforcing component inside the box body 1, and a cushioning component inside the box body 1. The reinforcing component enhances the strength of the box body 1, while the cushioning component provides shock absorption. The reinforcing component includes a bottom pad 8, which is fixedly connected inside the box body 1. An inner corner protector 7 is fixedly connected to the top of the bottom pad 8, and a reinforcing plate 6 is fixedly connected to the top of the inner corner protector 7. The reinforcing plates 6 are fixedly connected to each other. A limit plate frame 9 is connected to the bottom of the box 1, a base plate 3 is fixedly connected to the bottom of the box 1, a clamping plate 5 is fixedly connected to the side wall of the box 1, and outer corner guards 4 are fixedly connected to the four corners of the side wall of the box cover 2. The outer corner guards 4 can effectively prevent external impact from damaging the box cover 2. The box cover 2 is slidably connected to the side wall of the box 1, and the side wall of the box cover 2 is slidably connected to the inside of the clamping plate 5. Inner corner guards 7 are set at the four corners inside the box 1 to improve the pressure resistance of the four corners. Reinforcing plates 6 are set at the corners inside the box 1 to enhance the deformation resistance of the corners of the box 1.

[0029] The outer corner protectors 4 at the four corners of the lid 2 provide protection for the edges and corners of the lid 2, effectively resisting external impacts during transportation and handling, and extending the service life of the lid 2. The clamping plate 5 is installed on the side wall of the box body 1 to ensure the stability of the lid 2 during sliding connection, and to prevent loosening or falling off due to vibration or displacement. The reinforcing plate 6 and inner corner protectors 7 are arranged at the four corners and edges inside the box body 1, which not only increases the overall structural strength of the box body 1, but also improves the pressure resistance, enabling the box body 1 to withstand higher external impacts, while reducing the risk of deformation, thereby providing a safer storage environment for the contents.

[0030] Reference Figures 3-4 The buffer assembly includes a corrugated plate 12 and a spring strip 10. The corrugated plate 12 is fixedly connected to the top of the base pad 8 to effectively absorb external impact. The spring strip 10 is fixedly connected to the side wall of the limiting plate frame 9. The spring strip 10 has deformation capability to further buffer the impact. A pad 13 is fixedly connected to the top of the corrugated plate 12. A corrugated plate 14 is fixedly connected to the top of the pad 13. A placement plate 15 is fixedly connected to the top of the corrugated plate 14. A contact plate 11 is fixedly connected to each side of the spring strip 10.

[0031] The bottom pad 8 is placed inside the housing 1 to support and fix the cushioning components, enhancing the stability of the overall structure. Corrugated plate 12 and corrugated plate 14 absorb external impact through their corrugated structure, thereby reducing the damage to the internal items. Pad 13 and placement plate 15 provide a stable surface for placing items, while effectively dispersing the impact force to the corrugated structure, further improving the cushioning performance. The spring strip 10 deforms under external impact, and the cushioning force is evenly dispersed through the abutment plate 11, achieving a good effect of protecting the items.

[0032] Working principle: The lid 2 and the body 1 are sealed by sliding. The outer corner guards 4 at the four corners of the lid 2 provide edge protection for the lid 2. The clamping plate 5 ensures the stability of the lid 2 during the sliding connection. The reinforcing plate 6 and the inner corner guards 7 are arranged at the four corners and edges inside the body 1 to increase the structural strength and improve the compressive strength of the body 1.

[0033] Secondly, the bottom pad 8 is placed inside the box 1 to support and fix the cushioning components. Corrugated plate 12 and corrugated plate 14 absorb external impact through the corrugated structure. Pad 13 and placement plate 15 provide a stable surface for placing items, while effectively dispersing the impact force to the corrugated structure. The limiting plate frame 9 achieves structural stability by fixing the spring strip 10. The spring strip 10 deforms under external impact and disperses the cushioning force evenly through the abutment plate 11, thus achieving the effect of protecting the items.
