Description

Technical Field

[0001] This utility model relates to the field of profile technology, specifically to a multi-layer anti-damage profile for refrigerated boxes. Background Technology

[0002] Multi-layered, damage-resistant profiles for refrigerated boxes are key components ensuring the safe transport of refrigerated goods. Made from a composite of various materials, they cushion external impacts, resist environmental corrosion, and reduce the risk of damage to refrigerated goods during transport due to collisions and compression. They also enhance the insulation performance of the refrigerated box, maintaining a stable low-temperature environment inside, playing a vital role in cold chain logistics and other fields.

[0003] Application No. 202320726367.6 discloses a multi-layer profile for refrigerated container linings. The method involves creating several through slots on the lining bag to be installed, then fitting these slots onto each screw. This allows each rubber ring to be fitted onto each screw, and rotating a block secures each rubber ring, thus fixing the crossbars. Water bags are then used to compress the lining bag, further securing it. Injecting cold air into the container freezes the water in each water bag, causing the bags to collide and enhance the fixing effect. This method facilitates lining bag fixation while the gradual freezing of water provides reinforcement, preventing damage from over-fixing. Furthermore, the expansion of the frozen water eliminates the need for forceful tightening of the rotating block during fixing.

[0004] The aforementioned profiles have poor damage resistance; during frequent loading and unloading and long-distance transportation, they are unable to effectively absorb external impacts, leading to dents and cracks in the refrigerated boxes, affecting the preservation of the items inside. Furthermore, their poor corrosion resistance makes them susceptible to corrosion in complex environments such as humidity and low temperatures, shortening their service life and increasing operating costs. Moreover, their poor damage resistance may also damage the sealing and insulation structure of the refrigerated box, causing temperature fluctuations inside, affecting refrigeration performance, and even causing spoilage of goods, resulting in economic losses. Therefore, we propose a multi-layered, damage-resistant profile for refrigerated boxes. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-3 A multi-layered, damage-resistant profile for refrigerated boxes, comprising:

[0027] First aluminum plate 1;

[0028] The second aluminum plate 2 is disposed at the bottom end of the first aluminum plate 1;

[0029] The anti-damage component is disposed between the first aluminum plate 1 and the second aluminum plate 2 to improve the wear resistance of the first aluminum plate 1 and the second aluminum plate 2.

[0030] The first aluminum plate 1 and the second aluminum plate 2 serve as the outer load-bearing structure. When subjected to external pressure or impact, they transmit the force to the anti-damage component between them. The anti-damage component disperses and buffers the force through its own structure and material properties, reducing the direct effect of external force on the first aluminum plate 1 and the second aluminum plate 2, thereby improving their wear resistance.

[0031] Insulation boards 8 are fixedly connected to the inner walls of both the first aluminum plate 1 and the second aluminum plate 2.

[0032] When external heat attempts to enter the refrigerator, the insulation board 8 prevents heat transfer and maintains a low-temperature environment inside the refrigerator.

[0033] Damage protection components include reinforcing plate 6 and polyurethane foam 7;

[0034] The reinforcing plate 6 is fixedly connected between the two sets of insulation plates 8. The reinforcing plate 6 is X-shaped and has several reinforcing plates 6 arranged linearly.

[0035] Polyurethane foam 7 is filled between two reinforcing plates 6, and polyurethane foam 7 is located in the gap between adjacent reinforcing plates 6.

[0036] The reinforcing plate 6 in the damage protection component is X-shaped and linearly distributed between the two sets of insulation plates 8. When subjected to external force, it can disperse the concentrated force to multiple directions. The polyurethane foam 7 fills the gaps between the reinforcing plates 6 and absorbs the impact energy of the external force by its own elastic deformation. The two work together to buffer the external impact force. The reinforcing plate 6 and the polyurethane foam 7 in the damage protection component can efficiently absorb and disperse the external impact force, prevent the first aluminum plate 1 and the second aluminum plate 2 from denting or cracking, and extend the service life of the profile.

[0037] Rubber pads 5 are fixedly connected at both ends between the first aluminum plate 1 and the second aluminum plate 2;

[0038] A connecting box 3 is fixedly connected between the two rubber pads 5. The connecting box 3 is provided in two sets and is symmetrically arranged at both ends of the first aluminum plate 1 and the second aluminum plate 2. An arc plate 4 is fixedly connected to the inner wall of the connecting box 3.

[0039] The rubber pads 5 at both ends between the first aluminum plate 1 and the second aluminum plate 2 undergo elastic deformation when the device is squeezed or collided, thus buffering the force on the ends. The connecting box 3 is used to connect with other components of the refrigerator. The arc plate 4 on the inner wall enhances the structural strength of the connecting box 3 and helps to disperse the force on the ends. The design of the rubber pads 5, connecting box 3 and arc plate 4 not only improves the impact resistance of the profile ends, but also provides reliable support for the connection between the profile and the refrigerator, enhancing the stability of the overall structure.

[0040] The outer wall of the first aluminum plate 1 is provided with a fluorocarbon coating 9, and a polycarbonate 10 is provided at the end of the fluorocarbon coating 9 away from the first aluminum plate 1;

[0041] The fluorocarbon coating 9 on the outer wall of the first aluminum plate 1 resists external corrosive media with its chemical stability; the polycarbonate 10 protects the inner layer with its high strength and impact resistance; and the aluminum foil moisture-proof layer 11 isolates water vapor. The three together form a protective system to protect the first aluminum plate 1 and its internal structure.

[0042] An aluminum foil moisture barrier 11 is provided at the end of the polycarbonate 10 away from the fluorocarbon coating 9;

[0043] The aluminum foil moisture barrier 11 is located on the outside of the polycarbonate 10. Utilizing the density and barrier properties of the aluminum foil, it effectively prevents external moisture from entering the interior of the profile, protecting the internal structure from the effects of moisture.

[0044] Structural Description: First Aluminum Plate 1: As the outer structure of the profile, it is made of aluminum, which is high in strength and light in weight; its outer wall is provided with fluorocarbon coating 9, polycarbonate 10 and aluminum foil moisture-proof layer 11, forming a protective system; the inner side is connected to the insulation board 8, and together with the anti-damage components, it resists external pressure and corrosion, ensuring the performance of the profile.

[0045] The second aluminum plate 2 is installed corresponding to the first aluminum plate 1 and is also an outer load-bearing component; the inner wall is fixed with an insulation board 8, which together with the first aluminum plate 1 forms a protective space. With the cooperation of the damage prevention components, it withstands external impacts, protects the internal structure, and improves the durability of the profile.

[0046] Connecting box 3: Symmetrically arranged at both ends of the first aluminum plate 1 and the second aluminum plate 2, used for connecting the profile to other parts of the refrigerator; the inner wall arc plate 4 enhances the structural strength, and together with the rubber pad 5, it not only achieves a stable connection, but also buffers the force at the ends and improves the overall stability.

[0047] Arc plate 4: Fixed to the inner wall of the connecting box 3, the unique arc design enhances the pressure resistance of the connecting box 3; when the profile is subjected to external force, it helps to disperse the end stress, avoid stress concentration leading to damage, and ensure the reliability and service life of the connection part.

[0048] Rubber pad 5: Located at both ends of the first aluminum plate 1 and the second aluminum plate 2, it has good elasticity and can deform and buffer when the device is squeezed or collided; effectively reducing end wear, while enhancing the sealing and stability of the connection between the profile and the refrigerator.

[0049] Reinforcing plate 6: It is X-shaped and linearly distributed between the two sets of insulation plates 8; when the profile is subjected to external force, it can disperse the concentrated force, and together with polyurethane foam 7, absorb the impact energy, improve the impact resistance of the profile, and prevent dents and cracks.

[0050] Polyurethane foam 7: Fills the gap between the two reinforcing plates 6, and has high elasticity; after the reinforcing plates 6 disperse the force, it absorbs the remaining impact energy through its own deformation, and works in synergy with the reinforcing plates 6 to efficiently buffer external forces and protect the internal structure of the profile.

[0051] Insulation board 8: Fixed to the inner walls of the first aluminum plate 1 and the second aluminum plate 2 to form a heat insulation barrier; effectively preventing the entry of external heat, reducing the loss of cold air in the refrigerator, maintaining a low temperature environment, and ensuring the quality of refrigerated items.

[0052] Fluorocarbon coating 9: Coated on the outer wall of the first aluminum plate 1, it has strong chemical stability; it can resist corrosive media such as acids, alkalis and ultraviolet rays, prevent aluminum oxidation and aging, and provide long-term corrosion protection for the profile.

[0053] Polycarbonate 10: Covers the outside of fluorocarbon coating 9, with high strength and good impact resistance; it can resist external collisions and friction, protect the inner structure, and at the same time has good light transmittance, making it easy to observe in special scenarios.

[0054] Aluminum foil moisture barrier 11: Located on the outside of polycarbonate 10, it utilizes the dense properties of aluminum foil to effectively block moisture. This prevents the interior of the profile from being damaged by moisture, maintains stable insulation and damage prevention properties, and is suitable for use in humid environments.

[0055] Instructions for use

[0056] When the device is subjected to pressure, the first aluminum plate 1 and the second aluminum plate 2, as the outer structure, bear the pressure first. The insulation board 8 between them is squeezed and deformed, transmitting the pressure to the damage prevention component. The reinforcing plate 6 in the damage prevention component is X-shaped and linearly distributed, which can effectively disperse the pressure. The pressure further acts on the polyurethane foam 7 filling the gaps between the reinforcing plates 6. The polyurethane foam 7 absorbs the pressure through its own elastic deformation, realizing the buffering of the impact force. The rubber pads 5 fixedly connected at both ends between the first aluminum plate 1 and the second aluminum plate 2 play an elastic buffering role when the device is squeezed or collided, reducing the wear at the ends. The connecting box 3 between the two rubber pads 5 is symmetrically arranged at both ends. The arc plate 4 on the inner wall of the connecting box 3 further enhances the structural strength, while also helping to disperse the force at the ends. The connecting box 3 can also be used to connect and fix with other components of the refrigerator. The fluorocarbon coating 9, polycarbonate 10 and aluminum foil moisture-proof layer 11 arranged sequentially on the outer wall of the first aluminum plate 1 together constitute the protective system. The fluorocarbon coating 9 provides excellent corrosion resistance, resisting external acid, alkali, and humid environments; the polycarbonate 10 has high strength and impact resistance, protecting the inner structure; the aluminum foil moisture barrier 11 isolates moisture, preventing internal materials from being damaged by moisture; the insulation board 8, which is fixedly connected to the inner wall of the first aluminum plate 1 and the second aluminum plate 2, can still maintain its insulation function under pressure, reducing external heat transfer and ensuring a stable low-temperature environment inside the refrigerator.
