Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation boxes, and in particular relates to a thermal insulation box with a thermal insulation layer reinforcement structure. Background Art

[0002] Insulated containers are containers designed to maintain a constant internal temperature. They are widely used in key areas such as food transportation, pharmaceutical storage, and cold chain logistics. Their core function is to effectively isolate the internal microenvironment from external temperature fluctuations through a specialized structural design and carefully selected materials, ensuring that items within the container remain within a suitable temperature range for an extended period of time.

[0003] Thermal containers play a crucial role in numerous industries and are essential specialized equipment. In the food transportation sector, they ensure that food maintains the correct temperature throughout its journey. Whether it's fresh produce requiring refrigeration or hot food requiring heat preservation for delivery, thermal containers provide reliable temperature control, effectively preventing food spoilage and ensuring food quality and safety. Thermal containers also play a crucial role in pharmaceutical storage. Many pharmaceuticals require specific temperature conditions for storage and transportation to ensure their efficacy and safety. With their stable temperature control performance, thermal containers meet the stringent requirements of pharmaceutical storage and transportation, effectively preventing the risk of drug loss due to temperature fluctuations. Furthermore, thermal containers are essential equipment in cold chain logistics, which requires goods to be kept cool throughout transportation to prevent spoilage or damage. Thermal containers, with their excellent insulation performance, effectively maintain a low temperature environment within the container, fully meeting the temperature control needs of cold chain logistics.

[0004] However, it is worth noting that although the thermal insulation performance of the thermal insulation box is excellent, once its insulation layer is subjected to external impact, serious consequences may occur, causing the items in the box to be unable to maintain the required temperature, thus posing a threat to the preservation status of the items. Utility Model Content

[0005] In view of this, the utility model provides an insulation box with an insulation layer reinforcement structure, which can improve the strength of the insulation layer of the insulation box and improve the life and performance of the insulation box.

[0006] The utility model is achieved in this way:

[0007] The utility model provides an insulation box with an insulation layer reinforcement structure, which includes an insulation box body and a box cover, the insulation box body is a rectangular structure with an upper opening, the box cover is a rectangular box that matches the insulation box body, the top of the insulation box body is hinged to the box cover, the insulation box body and the box cover have an interlayer insulation layer inside, the insulation layer is used for insulation, and a reinforcement structure is distributed inside the insulation layer, and the reinforcement structure is used to strengthen the strength of the insulation layer.

[0008] On the basis of the above technical solution, the insulation box with a reinforced insulation layer structure of the present invention can also be improved as follows:

[0009] The arc-shaped iron sheet of the reinforcement structure is located inside the insulation layer, and the reinforcement structure comprises multiple pieces, which are staggeredly arranged inside the insulation layer.

[0010] Furthermore, the projections of the reinforcement structure on the inner side or the outer side of the thermal insulation layer overlap.

[0011] Furthermore, the cross section of the reinforcement structure is a sine curve.

[0012] The benefits of this improved solution include the use of curved iron sheets as reinforcement within the insulation layer of the insulation box, with multiple pieces staggered within the insulation layer. This design creates a complex support network that effectively disperses external impact forces and internal pressure, avoiding stress concentration and significantly enhancing the overall strength and stability of the insulation layer.

[0013] At the same time, the projections of the reinforcement structure on the inner or outer side of the insulation layer overlap, ensuring that there are no gaps or weak areas inside the insulation layer, further improving the strength and reliability of the overall structure.

[0014] In particular, the sinusoidal curve was chosen as the cross-sectional shape of the reinforcement structure, leveraging its unique elastic properties. When subjected to stress, the sinusoidal curve deforms to absorb the impact, while quickly returning to its original shape, demonstrating excellent fatigue resistance and durability. This design makes the reinforcement structure more flexible and reliable in responding to temperature fluctuations, vibration, or external impact, while also better protecting the insulation layer.

[0015] In summary, the staggered curved iron reinforcement structure, combined with a sinusoidal cross-section design, not only improves the overall strength and stability of the insulation box, but also maintains its structural flexibility and durability. This design enables the insulation box to perform well in a variety of application scenarios and has broad application prospects.

[0016] Furthermore, the insulation layer is provided with reinforcement corners around it, and the reinforcement corners are used to strengthen the strength of the corners of the insulation layer. The reinforcement corners are spatial right-angle structures composed of three right-angled triangles, and the reinforcement corners are located at the corners of the insulation box body and the box cover.

[0017] The beneficial effect of adopting this improved solution is that, in the design of the insulation box, reinforced corners are installed around the insulation layer. This structural innovation brings significant benefits. The reinforced corners are composed of three right-angled triangles and are located at the corners of the insulation box body and lid. Their main function is to strengthen the corners of the insulation layer.

[0018] Corners are the most vulnerable parts of an insulated box to bumps and damage. During transportation and use, insulated boxes may be subject to various external impacts, and corners are often the first to bear the brunt. If these corners are not adequately protected, they can easily break, compromising the integrity of the insulation.

[0019] If the edges and corners of the insulation layer are damaged, they create a channel for heat to escape. The main function of the insulation layer is to maintain a stable temperature within the box and prevent heat loss. However, if the edges and corners are damaged, heat will quickly escape through this weak link, significantly compromising the insulation effect.

[0020] Therefore, reinforcing the corners around the insulation layer significantly improves the box's impact resistance, reducing the risk of damage from bumps and bumps. Even if the box encounters external impact during transportation or use, the reinforced corners effectively absorb and disperse the force, protecting the insulation layer from damage. This helps the box maintain a more stable temperature inside, improving insulation effectiveness.

[0021] To sum up, the advantage of setting reinforced corners around the insulation layer is that it can prevent the four corners of the insulation layer from being damaged by bumps, thereby preventing temperature from escaping from the corners and ensuring the insulation effect of the insulation box.

[0022] Furthermore, the reinforcement structure is a spring, and the reinforcement structure is located inside the insulation layer.

[0023] The beneficial effect of adopting the above-mentioned improvement scheme is: in the design of the insulation box, the reinforcing structure is set as a spring and located inside the insulation layer. This innovative design brings significant benefits, namely, it can effectively prevent the insulation layer from being squeezed and deformed by external forces.

[0024] The main function of the insulation layer is to maintain a stable temperature within the box and prevent heat loss. However, in practice, insulated boxes may be subject to various external shocks and pressures, such as bumps during transportation and heavy pressure during stacking. These external forces can easily squeeze the insulation layer, causing it to deform or break, thereby compromising its insulation effectiveness.

[0025] As an elastic element, the spring has excellent resilience and compression resistance. When the insulation box is squeezed by external forces, the spring absorbs and disperses the impact, reducing its direct impact on the insulation layer. Furthermore, the spring's resilience allows the insulation layer to quickly return to its original shape after being squeezed, preventing permanent deformation.

[0026] Furthermore, placing the spring inside the insulation layer further increases its overall strength and stability. The spring's support enhances the insulation layer's ability to resist deformation, making it more robust and durable in the face of external impacts.

[0027] In summary, configuring the reinforcing structure as a spring and locating it within the insulation layer effectively prevents deformation of the insulation layer due to external forces, thereby improving the insulation effect and overall durability of the insulation box. This design innovation not only enhances the structural strength of the insulation box but also improves its reliability and stability in practical applications.

[0028] Furthermore, the length of the reinforcement structure is smaller than the thickness of the thermal insulation layer.

[0029] The beneficial effect of adopting the above-mentioned improvement scheme is to avoid leakage of the reinforced structure and reduce the thermal insulation performance.

[0030] Furthermore, the reinforcement structure is a tightly arranged hexagonal tube, and the thermal insulation box body and the box cover are, from the inside to the outside, an insulation layer, a reinforcement structure, and an insulation layer, and the axis of the reinforcement structure is parallel to the insulation layer.

[0031] Furthermore, the insulation layer and the reinforcement structure have the same thickness.

[0032] Furthermore, the insulation layer is made of polyurethane foam or polystyrene foam, and the reinforcement structure is made of aluminum alloy.

[0033] Compared with the prior art, the beneficial effects of the thermal insulation box with a thermal insulation layer reinforcement structure provided by the present invention are:

[0034] Significantly improve the overall strength and stability of the insulation box: By staggering multiple curved iron sheets inside the insulation layer as a reinforcement structure, a complex support network is formed, which effectively disperses external impact force and internal pressure, avoids stress concentration, and thus significantly enhances the overall strength and stability of the insulation layer.

[0035] Enhance the impact resistance of the corners of the insulation layer: A spatial right-angle structure consisting of three right-angled triangles is set around the insulation layer as a reinforcement corner, which significantly improves the impact resistance of the corners of the insulation box, reduces the risk of damage due to bumps, effectively prevents temperature from escaping from the corners, and ensures the insulation effect of the insulation box.

[0036] Effectively prevent the insulation layer from being deformed by external forces: the reinforcement structure is set as a spring and located inside the insulation layer. The excellent resilience and compression resistance of the spring are used to effectively absorb external impact forces and reduce their direct impact on the insulation layer. At the same time, the insulation layer can quickly return to its original shape after being squeezed, avoiding permanent deformation.

[0037] The structural design of the insulation box is optimized: the length of the reinforcement structure is shorter than the thickness of the insulation layer, preventing leakage of the reinforcement structure and reducing the impact on insulation performance. Furthermore, the use of closely spaced hexagonal tubes as the reinforcement structure further increases the overall strength and stability of the insulation layer. The axis of the reinforcement structure is parallel to the insulation layer, which helps maintain structural uniformity and stability.

[0038] Improved durability and reliability: The insulation layer is made of high-quality materials such as polyurethane foam or polystyrene foam, which offer excellent thermal insulation properties. The reinforced structure is made of high-strength materials such as aluminum alloy, which offers excellent corrosion resistance and durability. This material combination not only improves the insulation effect of the insulation box but also extends its service life.

[0039] Broad application prospects: The insulation box of the utility model has the characteristics of simple structure, high strength, good stability, and excellent insulation effect. It is suitable for various occasions requiring insulation, freshness preservation, and refrigeration, such as food transportation, medical storage, cold chain logistics and other fields, and has broad application prospects and market demand.

[0040] In summary, the present invention significantly improves the overall performance and practicality of the insulation box through a series of innovative designs and technical improvements, and provides a more reliable and efficient insulation solution for related industries.
