Description

Technical Field

[0001] This utility model relates to the field of agricultural product transportation packaging technology, specifically to a shock-absorbing and protective packaging frame for agricultural product transportation. Background Technology

[0002] Agricultural product packaging racks are structured support devices used to fix, separate, and protect agricultural products during transportation, storage, and sales. They typically serve as the internal skeleton or independent load-bearing unit of packaging boxes or containers to support fragile agricultural products such as fruits, vegetables, and eggs, preventing mechanical damage caused by collisions, squeezing, and vibration during distribution, and ensuring the freshness and commercial value of the products.

[0003] While common agricultural product transport packaging racks incorporate internal cushioning structures, often using materials like foam, sponge, or paper trays for protection, these traditional cushioning materials often exhibit insufficient resilience during long-distance transport. After continuous bumps, vibrations, and repeated compression, they are prone to plastic deformation or even collapse, failing to promptly return to their original shape. This leads to a gradual decline or even failure of the cushioning effect. Especially in high-temperature and high-humidity environments, some materials may soften or age, further weakening the protective capacity. This leaves agricultural products without effective protection in the later stages of transport, still facing a high risk of mechanical damage such as bruising, crushing, and cracking. This is particularly pronounced for high-value, easily damaged fruits with fragile skins and delicate textures, such as strawberries, cherries, and blueberries. The damage not only affects appearance and quality but may also accelerate spoilage, reducing commercial value and causing economic losses. This approach fails to meet the demands of modern agricultural product logistics for efficient, long-lasting, and reliable protection. Utility Model Content

[0004] This utility model aims to solve the problems of poor resilience, easy permanent deformation, decreased protective performance with transportation time, and insufficient structural strength of existing agricultural product packaging rack cushioning materials, and provides a shock-absorbing and protective packaging rack with fast rebound, good durability, reusability, and stable cushioning performance.

[0005] To address the shortcomings of existing technologies, this utility model provides a shock-absorbing and protective packaging frame for agricultural product transportation. The elastic fiber side net and bottom net form a three-dimensional mesh frame that deforms to absorb energy and rebounds quickly when subjected to force, effectively protecting fragile agricultural products. At the same time, the packaging units are integrally formed through flexible connecting parts, creating a stable honeycomb structure that can undergo localized micro-deformation to buffer impacts and prevent damage from hard compression. This solves the problem that common packaging frames often use foam, sponge, or paper cushions for cushioning, but these are prone to deformation and collapse during long-distance transportation due to continuous vibration and compression, have poor resilience, and are more likely to age and fail under high temperature and humidity, resulting in reduced protective power. This leads to bruising, crushing, and cracking of fragile fruits such as strawberries and cherries, accelerating rot, affecting quality, causing losses, and failing to meet the needs for long-term protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing and protective packaging frame for agricultural product transportation, comprising a honeycomb-shaped packaging frame and packaging units. The honeycomb-shaped packaging frame is divided into multiple layers, and the multi-layer honeycomb-shaped packaging frame is assembled. The honeycomb-shaped packaging frame is composed of multiple hexagonal packaging units, and adjacent packaging units are integrally connected by flexible connecting parts to form a honeycomb-shaped overall structure that can be locally deformed. Shock-absorbing and protective components are installed on the reinforced corners.

[0007] The shock absorption and protection components include connecting grooves opened on the reinforced corners, connecting sliders slidably installed in the connecting grooves, connecting plates connected to the connecting sliders, elastic fiber side meshes set between two opposing connecting plates, and elastic fiber bottom meshes embedded in the bottom of the six connecting plates.

[0008] Furthermore, the upper end of the packaging unit is provided with a snap-fit ​​plate, and the lower end of the packaging unit is provided with a snap-fit ​​groove. The adjacent honeycomb-shaped packaging racks are stacked by inserting the snap-fit ​​plate and the snap-fit ​​groove to form a multi-layer transportation structure.

[0009] Furthermore, the flexible connection is a thin-walled section that connects the side walls of adjacent packaging units. The flexible connection is integrally injection molded using the same elastic plastic material as the packaging unit. When adjacent packaging units are under pressure, their flexible connection will generate a small relative displacement to buffer and coordinate the pressure.

[0010] Furthermore, the elastic fiber side net and elastic fiber bottom net are woven from highly elastic and wear-resistant polyester fibers. When subjected to lateral or vertical impacts during transportation, the highly elastic elastic fiber side net and elastic fiber bottom net can cushion agricultural products.

[0011] Furthermore, the reinforcing corners also serve as reinforcing ribs, used to improve the structural strength at the corners of the packaging unit.

[0012] Furthermore, a silicone sealing ring is provided on the contact surface between the snap-fit ​​plate and the snap-fit ​​groove, which enhances the stability of the connection between the upper and lower packaging units.

[0013] Furthermore, the connecting slider and the reinforcing corner are separate structures. During the assembly of the packaging unit, the connecting slider slides into the connecting groove. After the main body of the packaging unit is formed, the honeycomb packaging frame is formed and assembled.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The shock absorption and protection components adopt a three-dimensional mesh structure with elastic fiber side mesh and elastic fiber bottom mesh. When bumps, collisions or stacking occur during transportation, the highly elastic and wear-resistant polyester fiber mesh quickly deforms to absorb energy and quickly rebounds to restore its original shape, reducing the risk of agricultural products being bruised, crushed, or cracked. It is especially suitable for long-distance transportation of fragile agricultural products such as strawberries, cherries, and kiwis.

[0016] 2. By integrating flexible connecting parts between adjacent packaging units, multiple hexagonal packaging units form a continuous honeycomb structure, which not only ensures the integrity and structural stability of the packaging frame, but also allows each unit to generate slight relative displacement through the flexible connecting parts when under pressure, realizing local deformation buffering, effectively absorbing vibration and impact during transportation, and preventing agricultural products from being damaged by rigid compression.

[0023] 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.

[0024] This packaging rack has a robust structure, and its cushioning components can maintain their performance over a long period of time. It supports multiple cleanings and reuses, reducing packaging costs and resource waste, and is in line with the trend of green logistics development.

[0025] Please see Figure 1The shock-absorbing and protective packaging frame for agricultural product transportation in this embodiment includes a honeycomb-shaped packaging frame 1 and packaging units 2. The honeycomb-shaped packaging frame 1 is divided into multiple layers. The multi-layer honeycomb-shaped packaging frame 1 is assembled. The honeycomb-shaped packaging frame 1 is composed of multiple hexagonal packaging units 2. Adjacent packaging units 2 are integrally connected by flexible connecting parts 11 to form a honeycomb-shaped overall structure that can be locally deformed. Shock-absorbing and protective components are installed on the reinforced corners 3.

[0026] In this embodiment, the shock-absorbing and protective component adopts a three-dimensional mesh frame composed of elastic fiber side mesh 7 and bottom mesh, which can deform and absorb energy and rebound quickly when bumped or squeezed, effectively protecting fragile agricultural products such as strawberries and cherries. At the same time, adjacent packaging units 2 are integrally formed through flexible connecting parts 11 to form a stable honeycomb structure, allowing local micro-deformation to buffer the impact and avoid rigid compression damage.

[0027] Please see Figures 1-5 In this embodiment, in order to achieve a flexible net structure composed of elastic fiber side net 7 and bottom net, which can deform and buffer like a spring when subjected to force to protect the fruit from being bumped or crushed, the shock absorption and protection component in this embodiment includes a connecting groove 4 opened on the reinforcing corner 3, a connecting slider 5 slidably installed in the connecting groove 4, a connecting plate 6 connected to the connecting slider 5, an elastic fiber side net 7 disposed between two opposite connecting plates 6, and an elastic fiber bottom net 8 embedded in the bottom of the six connecting plates 6.

[0028] In this embodiment, the shock-absorbing and protective component is used to buffer impacts during transportation and protect agricultural products. It has a connecting groove 4 inside, and the connecting slider 5 can slide in the groove for easy assembly. The connecting plate 6 is fixed on the slider and serves as a support structure for installing the elastic fiber side net 7 and the bottom net. The side net is connected between two opposite connecting plates 6 to form a four-sided protection. When subjected to lateral impact, it can elastically deform to absorb energy. The bottom net is embedded in the bottom of the six connecting plates 6 to form a support surface, which can buffer vertical pressure and vibration. The whole component forms a flexible net structure that deforms and rebounds like a spring under force, preventing fruit from being damaged by collision or squeezing. This component works in conjunction with the reinforcing angle 3 to improve local strength, ensure stable and reliable buffering performance, and effectively protect the integrity of fragile agricultural products such as strawberries and cherries during long-distance transportation.

[0029] It should be noted that the elastic fiber side net 7 and elastic fiber bottom net 8 are woven from highly elastic and wear-resistant polyester fibers. When subjected to lateral or vertical impacts during transportation, the highly elastic elastic fiber side net 7 and elastic fiber bottom net 8 can cushion the agricultural products. The reinforcing corner 3 also serves as a reinforcing rib structure, used to improve the structural strength of the corners of the packaging unit 2. The elastic fiber side net 7, woven from highly elastic and wear-resistant polyester fibers, has good tensile strength and resilience. It can undergo elastic deformation when subjected to lateral impacts, absorbing vibration energy and mitigating collisions between agricultural products, thus playing a lateral buffering protection role. The elastic fiber bottom net 8, woven from highly elastic and wear-resistant polyester fibers, has strong pressure resistance and resilience. It can deform when subjected to vertical pressure or bumps, cushioning bottom impacts and preventing damage to agricultural products due to squeezing or vibration. The reinforcing corner 3 is made of high-strength materials, with a robust structure, which can enhance the pressure resistance of the corner areas of the packaging unit 2, resist external extrusion, prevent corner deformation or breakage, and at the same time serve as a support point to improve the overall structural stability.

[0030] Please see Figures 3-5 In this embodiment, to achieve a flexible connection between packaging units 2, which is integrally formed, the whole is firm yet slightly deformable, and plays a shock-absorbing role to prevent damage caused by hard collisions during transportation, the upper end of the packaging unit 2 in this embodiment is provided with a snap-fit ​​plate 9, and the lower end of the packaging unit 2 is provided with a snap-fit ​​groove 10. The upper and lower adjacent honeycomb-shaped packaging racks 1 are stacked by inserting the snap-fit ​​plate 9 and the snap-fit ​​groove 10 to form a multi-layer transportation structure. The flexible connection part 11 is a thin-walled section that connects the side walls of adjacent packaging units 2. The flexible connection part 11 is integrally injection molded using the same elastic plastic material as the packaging unit 2. When adjacent packaging units 2 are under pressure, their flexible connection parts 11 will generate a small relative displacement to buffer and coordinate the pressure.

[0031] In this embodiment, the snap-fit ​​plate 9 is disposed on the upper end of the packaging unit 2 and is used to cooperate with the snap-fit ​​groove 10 at the lower end of another packaging unit 2 to realize quick insertion between the upper and lower layers, so that the multi-layer packaging rack can be stacked stably, preventing misalignment or tipping during transportation and improving stacking safety. The snap-fit ​​groove 10 is disposed on the lower end of the packaging unit 2 and matches the snap-fit ​​plate 9 of the upper packaging unit 2. A firm connection is formed by the insertion method, which helps to realize the stable assembly of the multi-layer structure and enhances the overall vibration resistance. The flexible connection part 11 is made of elastic plastic material and connects adjacent packaging units 2. It has a certain degree of flexibility and bending ability. When subjected to external force, it can produce slight deformation, absorb impact energy, coordinate the force distribution between units, play a local buffering role, and avoid damage caused by rigid collision.

[0032] It should be noted that the contact surfaces of the snap-fit ​​plate 9 and the snap-fit ​​groove 10 are provided with silicone sealing rings. The silicone sealing rings enhance the stability of the connection between the upper and lower packaging units 2. The connecting slider 5 and the reinforcing corner 3 are separate structures. When the packaging unit 2 is assembled, the connecting slider 5 slides into the connecting groove 4. After the main body of the packaging unit 2 is formed, the honeycomb packaging frame 1 is formed and assembled.

[0033] It should be added that during the assembly of the packaging rack, after the connecting slider 5 slides into the connecting groove 4, it is positioned by interference fit to prevent it from sliding out on its own during transportation and to ensure the structural stability of the connecting plate 6.

[0034] Of the six sides of each hexagonal packaging unit 2, three to six are connected to adjacent packaging units 2 through flexible connecting parts 11, and are symmetrically distributed to ensure the integrity of the whole while allowing local elastic deformation.

[0035] The main body of packaging unit 2 is integrally injection molded from high-impact polypropylene or polyethylene, and the thickness of the flexible connection part 11 is 0.8 to 1.5 mm, which is 1 / 3 to 1 / 2 of the thickness of its side wall.

[0036] The elastic fiber side mesh 7 and the elastic fiber bottom mesh 8 are made of polyester high elastic yarn or spandex blended mesh fabric with a breaking elongation of ≥30% and excellent resilience. The flexible connection part 11 can generate 0.5 to 2 mm of elastic displacement when subjected to force, effectively absorbing impact energy and preventing stress concentration.

[0037] The working principle of the above embodiments is as follows:

[0038] In use, the packaging unit 2 is manufactured using an integrated injection molding process. Adjacent units are connected by flexible connecting parts 11 to form an overall honeycomb structure. The snap-fit ​​plate 9 and snap-fit ​​groove 10 on the packaging unit 2 are used for interlocking and stacking between upper and lower layers. During assembly, the connecting slider 5 is slid into the reinforcing corner 3 along the connecting groove 4 to complete the sliding assembly. The connecting plate 6 is fixed on the slider as a support. The elastic fiber side net 7 is installed between the opposite connecting plates 6 to form a four-sided protection. The elastic fiber bottom net 8 is embedded in the bottom of the six connecting plates 6 to form a support surface. When bumps or squeezing occur during transportation, the side net absorbs the lateral impact, the bottom net buffers the vertical vibration, the overall net structure undergoes elastic deformation and rebounds quickly, and the flexible connecting parts 11 generate a small displacement when under pressure, coordinating local forces and dispersing impact energy. The silicone sealing ring enhances the stability of the upper and lower layer connections and prevents loosening and falling off, thereby comprehensively protecting agricultural products from collision and crushing.
