Description

Technical Field

[0001] This utility model relates to the field of anti-collision cushioning technology, and in particular to an anti-collision cushioning packaging box for eggs. Background Technology

[0002] In the food supply chain, eggs, as high-value and fragile agricultural products, are easily damaged by collisions and vibrations during transportation, storage, and handling due to their fragile shell structure. This not only causes economic losses but may also lead to food safety issues. According to statistics, traditional packaging methods severely restrict industry efficiency. To address this problem, anti-collision cushioning packaging boxes have emerged. This type of packaging uses the synergistic effect of physical structure and cushioning materials to convert external forces into absorbable deformation energy, effectively reducing the risk of egg damage. Its core components include a rigid shell, an elastic cushioning layer, and a positioning support structure. Common materials such as corrugated paper and pearl cotton can disperse impact forces to a certain extent. However, traditional cushioning packaging has obvious drawbacks. The thickness of the cushioning layer increases the packaging volume, leading to higher transportation costs. The cushioning performance of a single material is limited, and the protective effect is not good when facing high-frequency vibration and severe impact. Moreover, most structures lack adaptive adjustment capabilities and are difficult to adapt to different egg sizes.

[0003] To overcome the limitations of traditional packaging, mechanical structure innovation has become a key direction for technological breakthroughs. Early mechanical solutions used foldable corrugated cardboard supports, achieving multi-angle cushioning through a three-dimensional honeycomb structure. However, this structure lacks the ability to disperse complex external forces, and its cushioning performance significantly decreases after repeated use. In recent years, existing technologies have used suspension fixing devices based on the principles of springs and dampers, which can dynamically adjust the cushioning force through elastic elements, significantly improving impact resistance. Pneumatic adaptive cushioning chambers utilize the gas compression characteristics to intelligently adjust the cushioning effect according to the collision intensity. However, existing technologies suffer from high costs, complex structures leading to low packaging efficiency, and the inability to provide multi-level vibration reduction to reduce the probability of egg damage, resulting in low practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an egg anti-collision cushioning packaging box, which aims to improve the problem that the existing technology cannot reduce the probability of egg damage by multi-level vibration reduction and has low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an egg anti-collision buffer packaging box, including a packaging shell, a plurality of hinges fixedly connected to the top of the packaging shell, a cover plate fixedly connected to the top of the hinges, a vibration damping mechanism provided on the inner wall of the packaging shell, and a locking mechanism provided on the front side of the packaging shell, the locking mechanism being used for quick installation and disassembly. The vibration damping mechanism includes a protective plate, on the inner wall of which multiple eggs are slidably connected. Multiple vibration damping and buffering components are provided at the bottom of the protective plate, and a damping component is provided at the top of the protective plate.

[0006] As a further description of the above technical solution: The locking mechanism includes a U-shaped plate, the rear side of which is fixedly connected to the front side of the cover plate. A rotating shaft is rotatably connected to the inner wall of the U-shaped plate, and an L-shaped plate is rotatably connected to the outer wall of the rotating shaft. A limit component is provided on the front side of the packaging shell.

[0007] As a further description of the above technical solution: The vibration damping and buffer assembly includes an elastic plate. Multiple elastic plates are fixedly connected to the bottom of the protective plate, and a spring is slidably connected to the outer wall of the elastic plate.

[0008] As a further description of the above technical solution: The damping component includes a base column, the bottom of which is fixedly connected to the top of the protective plate, and a spring column is fixedly connected to the top of the base column. A vibration damping component is provided on the top of the spring column.

[0009] As a further description of the above technical solution: The vibration damping component includes a damper, the bottom of which is fixedly connected to the top of the spring column, a fixing plate is fixedly connected to the top of the damper, and a pneumatic buffer component is provided on the outer wall of the spring column.

[0010] As a further description of the above technical solution: The pneumatic buffer assembly includes a pneumatic chamber, the inner wall of which is slidably connected to the outer wall of the spring column, an air inlet valve is fixedly connected to the top of the pneumatic chamber, and an exhaust valve is fixedly connected to the top right side of the air inlet valve.

[0011] As a further description of the above technical solution: The limiting component includes a limiting plate, the rear side of which is fixedly connected to the front side of the packaging shell. Springs are slidably connected to the left and right sides of the inner wall of the limiting plate, and engaging components are provided on the left and right sides of the springs.

[0012] As a further description of the above technical solution: The engaging assembly includes a wedge block, the left and right sides of which are fixedly connected to the left and right sides of the second spring, and a wedge plate is slidably connected to each adjacent side of the wedge block.

[0013] This utility model has the following beneficial effects: 1. In this utility model, multiple raw eggs are placed in the holes of the protective plate. When subjected to external force, the spring deforms, converting kinetic energy into elastic potential energy, thus achieving initial shock absorption. At the same time, the fixed plate compresses the spring column and the damper. The spring column absorbs energy through compression, and the damper consumes energy synchronously. The two work together to gradually dissipate the impact energy, thereby protecting the eggs. Meanwhile, when subjected to external force, the gas inside the air pressure chamber is compressed, the air pressure increases, and the gas is slowly discharged through the exhaust valve. After the external force disappears, the air inlet valve automatically opens, and the air pressure chamber is re-intaken to restore its original state. This achieves multi-stage vibration reduction and effectively reduces the probability of egg damage, thus enhancing practicality.

[0014] 2. In this utility model, when the packaging box is closed, rotating the hinge causes the L-shaped plate to rotate its pivot, which in turn causes the wedge plate to rotate synchronously. This allows the rear side of the wedge plate to engage with the front side of the wedge block, compressing the second spring. This causes the wedge plate to slide to the rear side of the inner wall of the limiting plate. The second spring then returns to its original state, locking the wedge plate in place. When it is necessary to open the cover, rotating the wedge plate in the opposite direction compresses the wedge block, disengaging the wedge plate from the limiting position and opening it. This achieves the function of opening and closing the outer packaging box as needed, enhancing its practicality. Attached Figure Description

[0022] Working principle: Multiple raw eggs 202 are placed in the holes of the protective plate 201. When subjected to external force, spring 2032 deforms, converting kinetic energy into elastic potential energy, thus achieving initial shock absorption. At the same time, the fixed plate 2052 compresses the spring column 2042 and the damper 2051. The spring column 2042 absorbs energy through compression, and the damper 2051 consumes energy synchronously. The two work together to gradually dissipate the impact energy, thereby protecting the eggs. Meanwhile, when subjected to external force, the gas inside the pressure chamber 2061 is compressed, and the air pressure increases. The gas is slowly discharged through the exhaust valve 2063. After the external force disappears, the air inlet valve 2062 automatically opens, and the pressure chamber 2061 re-intakes air and returns to its original state. This achieves multi-stage vibration reduction, effectively reducing the probability of egg damage and enhancing practicality. When closing the packaging box, rotating hinge 5 causes L-shaped plate 303 to rotate shaft 302, which in turn causes wedge plate 3052 to rotate synchronously. This allows the rear side of wedge plate 3052 to engage with the front side of wedge block 3051, compressing spring 2 3042. This causes wedge plate 3052 to slide to the rear side of the inner wall of limiting plate 3041. Spring 2 3042 then returns to its original state, locking wedge plate 3052 in place. When it is necessary to open cover 4, rotating wedge plate 3052 in the opposite direction compresses wedge block 3051, disengaging wedge plate 3052 from the limiting position and opening it. This achieves the function of opening and closing the outer packaging box as needed, enhancing its practicality.
