[0038] Please refer to Figures 1-4 , a cold storage box for cold chain transportation, and the specific implementation is as follows:
[0039] The structures of the box body and the box cover
[0040] In this embodiment, the cold storage box includes a box body 1 and a box cover 2. The exterior of the box body 1 is made of high-strength materials, such as ABS plastic or composite materials, which have good impact resistance and durability and are suitable for use in harsh transportation environments. The box cover 2 is tightly fitted with the box body 1 through a sealing strip. The sealing strip is made of flexible rubber material to ensure that the inside of the cold storage box is isolated from the outside air in the closed state, prevent cold air from leaking, and maintain a low-temperature environment inside the box. In addition, a locking device is also provided between the box cover 2 and the box body 1 to ensure that the box cover will not accidentally open during transportation, further enhancing the safety of the box body.
[0041] The setting of the thermal insulation inner liner
[0042] A thermal insulation inner liner 3 is snap-fitted inside the box body 1. The thermal insulation inner liner 3 is designed with a three-layer structure to enhance the thermal insulation performance of the box body in multiple directions and extend the cold storage time.
[0043] Outer thermal insulation layer 31: The outer thermal insulation layer is made of polyurethane foam plastic. This material has a low thermal conductivity and good compressive properties, which can effectively prevent external heat from conducting into the box. In addition, the lightweight characteristic of polyurethane foam plastic also helps to reduce the weight of the box body, facilitating transportation and handling.
[0044] Thermal reflection layer 32: The thermal reflection layer is made of multiple layers of aluminized polyester film material, which can effectively reflect infrared rays and other forms of radiant heat, prevent external radiant heat from entering the box, and further improve the overall thermal insulation effect of the box body. The thermal reflection layer is closely attached to the outer thermal insulation layer to ensure that heat cannot penetrate through the gaps, thus maintaining a low-temperature environment inside the box body.
[0045] Inner thermal insulation layer 33: The inner thermal insulation layer is made of polystyrene foam plastic. This material has good thermal insulation performance and can maintain the stability of the internal temperature. At the same time, polystyrene foam plastic also has a certain buffering effect, which can protect the items inside the box from impact damage during transportation. The surface of the inner thermal insulation layer has been specially treated, with corrosion resistance and easy cleanability, ensuring good hygiene conditions during long-term use.
[0046] The design of the item-taking component
[0047] Inside the heat-insulating inner container 3, an article-taking component 4 is provided. This component is reasonably designed and has a compact structure, aiming to facilitate users to quickly and easily take and place items in a low-temperature environment.
[0048] Bottom support plate 41: The bottom support plate is made of high-density polyethylene (HDPE) material, has high strength and low-temperature resistance, and can maintain a stable shape in a low-temperature environment without shrinking or deforming due to freezing. The bottom support plate 41 is flat and smooth, and can support the items inside the box.
[0049] Side connecting plates 42: The side connecting plates 42 are located at the central positions of the left and right edges of the bottom support plate 41, and are made of high-strength metal or engineering plastics, providing sufficient supporting force to fix the handle 43. The side connecting plates are fixedly connected to the bottom support plate to ensure that they will not loosen or deform when extracting or placing items.
[0050] Handle 43: The handle is designed according to ergonomics, and its surface is covered with an anti-slip rubber layer, with a comfortable feel, facilitating users to operate under cold conditions. The handle is connected to the side connecting plate 42 by bolts or buckles, and users can easily extract the bottom support plate and the items above it through the handle.
[0051] Anti-slip design
[0052] To improve the safety of the cold storage box under different transportation conditions, in this embodiment, a rectangular frame-shaped anti-slip pad 6 is provided along the edge at the bottom of the box body 1. The anti-slip pad 6 is made of wear-resistant rubber and has a high friction coefficient, which can effectively prevent the box body from sliding on a smooth surface. The anti-slip pad is fixed to the bottom of the box body by adhesives or buckles. The thickness of the anti-slip pad is appropriate, which can not only provide sufficient anti-slip performance but also not affect the stability of the box body. In addition, the anti-slip pad has a certain shock-absorbing effect and can reduce the impact of vibration on the items inside the box during transportation.
[0053] Application of locking bolts
[0054] To prevent the box body from accidentally opening during transportation, locking bolts 5 are provided at the front and rear inner walls inside the box body 1. The locking bolts 5 are made of stainless steel, have high strength and corrosion resistance, and can be used for a long time in a harsh environment. The threaded part of the locking bolt is precisely processed to ensure a strong locking effect when screwed, so that the heat-insulating inner container 3 can be taken out. Furthermore, after the outer box body 1 is damaged by collision, the internal heat-insulating inner container 3 can be taken out and the outer box body 1 can be replaced.
[0055] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
