Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold chain transportation, specifically a food preservation cold chain transportation box. Background Technology
[0002] Food preservation cold chain transport boxes are key tools for ensuring the quality stability of temperature-sensitive items such as fresh produce and medicine during transportation. Their core function is to extend the shelf life of items and reduce losses through heat insulation, intelligent temperature control, and environmentally friendly design.
[0003] Mainstream cold chain transport boxes use high-density insulation materials (such as food-grade LLDPE and polyurethane foam) or vacuum insulation panels to maintain a low internal temperature environment by reducing heat conduction and convection. For example, food cold chain boxes are formed in one piece using a rotary molding process, resulting in a strong airtight seal that can keep food fresh for a long time.
[0004] In actual transportation, multiple transport boxes are usually placed on a cutting board to increase the amount of items transported at one time. Unloading is then carried out using a forklift and the cutting board. Since the multiple transport boxes are not connected to each other, they are prone to shaking during unloading. When stacked transport boxes encounter these shaking or accidental collisions, they are prone to falling at an angle, which can damage the food inside. Therefore, a food preservation cold chain transport box is proposed to address the above problems. Utility Model Content

[0018] 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 scope of protection of the present utility model.
[0019] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail. This application discloses a cold chain transport box for food preservation. (Refer to...) Figure 1 , Figure 2 and Figure 6A food preservation cold chain transportation box includes an insulated box body 1. A connecting frame 11 is fixedly connected to the outer wall of the insulated box body 1. A support plate 12 is fixedly connected to the outer wall of the insulated box body 1. A connecting post 13 is slidably contacted on the inner wall of the support plate 12. A first limiting block 14 is fixedly connected to the side wall of the connecting post 13. A spring 15 is fixedly connected to the side wall of the first limiting block 14. The support plate 12 is fixedly connected to the side wall of the spring 15. A connecting block 16 is fixedly connected to the outer wall of the insulated box body 1. The connecting block 16 and the connecting frame 11 are symmetrically arranged. A limiting groove 17 is formed on the side wall of the connecting block 16. When the equipment is working, food is placed inside the insulated box body 1. When multiple insulated box bodies 1 are being transported simultaneously, the insulated box bodies 1 filled with food are arranged in an orderly manner, and the ends of two insulated box bodies 1 are connected. At this time, the connecting block 16 of one insulated box body 1 will connect with the connecting frame 11 of another insulated box body 1. When the insulated box body 1 is in a close proximity, push the insulated box body 1 so that the connecting block 16 is inserted into the connecting frame 11. The connecting block 16 will contact the curved side of the first limiting block 14. The connecting block 16 will press the first limiting block 14, at which time the spring 15 will be stretched and the connecting column 13 will slide. Continue to push the connecting block 16 until the connecting block 16 is fully in contact with the connecting frame 11. At this time, the first limiting block 14 will coincide with the limiting groove 17. The connecting column 13 will push the first limiting block 14 to reset, thereby initially fixing the connecting block 16. Through the connection block 16 and the first limiting block 14, when multiple insulated box bodies 1 are loaded, multiple insulated box bodies 1 can be connected sideways, increasing the stability of the connection between multiple insulated box bodies 1 and reducing the possibility of multiple insulated box bodies 1 tilting and falling when encountering accidental collisions or shaking during loading and transportation, making it easier for staff to use the equipment.
[0020] Reference Figure 1 and Figure 5A limiting strip 2 is fixedly connected to the side wall of the insulated box body 1. A limiting plate 21 is fixedly connected to the side wall of the limiting strip 2. A limiting frame 22 is fixedly connected to the outer side wall of the insulated box body 1. A connecting plate 23 is slidably contacted on the inner side wall of the limiting frame 22. A connecting strip 24 is rotatably connected to the inner side wall of the connecting plate 23. A connecting groove 25 is opened on the side wall of the connecting strip 24. The connecting strip 24 and the limiting strip 2 are located on the same vertical line. The limiting strip 2 is located below the limiting frame 22. When the equipment is working, when multiple insulated box bodies 1 are stacked, the connecting strip 24 is rotated so that the connecting groove 25 is on top, and the connecting strip 24 is pulled. At this time, the connecting plate 23 will slide along the limiting frame 22. When the connecting groove 25 can contact the limiting strip 2, adjust the connecting groove 25 until the connecting strip 24 can be hung above the limiting strip 2. Release the connecting strip 24. At this time, under its own weight, the connecting plate 23 will slide downward. The limiting strip 2 slides to the side of the connecting groove 25 without a gap. The limiting plate 21 then restricts the connecting groove 25 to a certain extent. Through the setting of the limiting plate 21 and the connecting strip 24, the staff can connect the equipment vertically from multiple insulation box bodies 1 when stacking equipment, increasing the stability of the equipment when stacking.
[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer wall of the heat preservation box body 1 is fixedly connected to a second limiting block 3. The inner wall of the second limiting block 3 is slidably in contact with a contact strip 31. The side wall of the contact strip 31 is fixedly connected to a connecting plate 32. The side wall of the connecting plate 32 is fixedly connected to a connecting column 13. The inner wall of the contact strip 31 is fixedly connected to a connecting shaft 33. The outer wall of the connecting shaft 33 is rotatably connected to a contact rod 34. When the operator needs to separate the equipment connected to the side, the contact rod 34 is rotated to the other side. The operator pushes the contact rod 34 to make the contact strip 31 slide. The contact strip 31 pushes the connecting plate 32 to move, which in turn causes the connecting plate 32 to pull the connecting column 13 to slide until the first limiting block 14 disengages from the limiting groove 17. At this time, the connecting block 16 can disengage from the connecting frame 11. When the equipment is finished using the equipment, the contact rod 34 is rotated to the inside of the contact strip 31. Through the contact rod 34 and the connecting plate 32, the operator can quickly separate the connection between the equipment, which is convenient for the operator to use the equipment.
[0022] Reference Figure 1 , Figure 2 and Figure 7A fixing post 4 is fixedly connected to the outer wall of the heat preservation box body 1. A connecting sleeve 41 is rotatably connected to the outer wall of the fixing post 4. A fixing cylinder 42 is fixedly connected to the outer wall of the heat preservation box body 1. The fixing cylinder 42 and the fixing post 4 are symmetrically arranged. During the stacking operation, the connecting sleeves 41 and the fixing cylinder 42 between multiple heat preservation box bodies 1 are brought into contact with each other. The connecting sleeves 41 are inserted into the fixing cylinder 42, and the connecting sleeves 41 are rotated. At this time, the equipment can be connected to each other from the other side. The connecting sleeves 41 and the fixing cylinder 42 are designed to adapt to different loading environments, allowing the equipment to be connected from multiple directions, further increasing the stability of the connection between the equipment.
[0023] Reference Figure 3 A support strip 5 is fixed to the top of the outer wall of the support plate 12. The support strip 5 is in contact with the first limiting block 14. When the first limiting block 14 moves, the support strip 5 will restrict the direction of movement of the first limiting block 14. By setting the support strip 5, the stability of the first limiting block 14 when moving is increased, the tilting of the first limiting block 14 during long-term operation is reduced, and the failure rate of the equipment is reduced.
[0024] Reference Figure 4 A rubber pad 6 is fixed to the side wall of the contact rod 34. When the operator pushes the contact rod 34, the operator's palm will first come into contact with the rubber pad 6. The rubber pad 6 increases the friction between the operator's palm and the contact rod 34, thereby increasing the operator's comfort when using the equipment.
[0025] Reference Figure 3 The support plate 12 is made of rigid material. When the equipment is working, the support plate 12 plays an important supporting role. By setting the support plate 12 to be made of rigid material, the probability of the support plate 12 bending and breaking during long-term operation is reduced, thus extending the service life of the equipment.
[0026] Working principle: When the equipment is working, food is placed inside the insulated box body 1. When multiple insulated box bodies 1 are being transported simultaneously, the insulated box bodies 1 filled with food are arranged in an orderly manner, and the ends of two insulated box bodies 1 are connected. At this time, the connecting block 16 of one insulated box body 1 will be close to the connecting frame 11 of another insulated box body 1. Pushing the insulated box body 1, the connecting block 16 is inserted into the connecting frame 11. The connecting block 16 will contact the curved side of the first limiting block 14, and the connecting block 16 will compress the first limiting block 14. At this time, the spring 15 will be stretched, and the connecting column 13 will slide, continuously pushing the connecting block 16 until the connecting block 16 is fully in contact with the connecting frame 11. At this time, the first limiting block... 14 will overlap with the limiting groove 17, and the connecting column 13 will push the first limiting block 14 to reset, thereby initially fixing the connecting block 16. Through the connection block 16 and the first limiting block 14, when multiple insulated box bodies 1 are loaded, the multiple insulated box bodies 1 can be connected sideways, increasing the stability of the connection between the multiple insulated box bodies 1, reducing the possibility of multiple insulated box bodies 1 tilting and falling when encountering accidental collisions or shaking during loading and transportation, and facilitating the use of the equipment by the staff. When the equipment is working, when multiple insulated box bodies 1 are stacked, the connecting strip 24 is rotated so that the connecting groove 25 is on top, and the connecting strip 24 is pulled. At this time, the connecting plate 23 will slide along the limiting frame 22. When the connecting groove 25 can be aligned with the limiting... When strip 24 makes contact, adjust the connecting groove 25 until the connecting strip 24 can be hung above the limiting strip 2. Release the connecting strip 24. At this time, under its own weight, the connecting plate 23 will slide downward. The limiting strip 2 slides to the side of the connecting groove 25 without a notch. The limiting plate 21 then restricts the connecting groove 25 to a certain extent. Through the setting of the limiting plate 21 and the connecting strip 24, the staff can vertically connect the equipment from multiple insulation box bodies 1 when stacking equipment, increasing the stability of the equipment when stacking. When the staff needs to separate the equipment connected on the side, rotate the contact rod 34 to the other side. The staff pushes the contact rod 34 to make the contact strip 31 slide. The contact strip 31 pushes the connecting plate 32 to move. The movement causes the connecting plate 32 to pull the connecting column 13 to slide until the first limiting block 14 disengages from the limiting groove 17. At this point, the connecting block 16 can disengage from the connecting frame 11. After use, the contact rod 34 is rotated into the contact strip 31. Through the contact rod 34 and the connecting plate 32, the operator can quickly separate the connection between the equipment, facilitating the operation of the equipment. During stacking, the connecting sleeve 41 and the fixed cylinder 42 between multiple insulation box bodies 1 are brought into contact. The connecting sleeve 41 is inserted into the fixed cylinder 42, and the connecting sleeve 41 is rotated. At this point, the equipment can be connected to each other from the other side. The connecting sleeve 41 and the fixed cylinder 42 facilitate adaptation to different loading environments.This design allows the equipment to be connected from multiple directions, further increasing the stability of the connections between devices. When the first limit block 14 moves, the support bar 5 restricts the direction of movement of the first limit block 14. The support bar 5 increases the stability of the first limit block 14 during movement, reducing the likelihood of tilting during prolonged operation and lowering the equipment failure rate. When the operator pushes the contact rod 34, their palm will preferentially contact the rubber pad 6. The rubber pad 6 increases the friction between the operator's palm and the contact rod 34, increasing operator comfort. During operation, the support plate 12 plays a crucial supporting role. By making the support plate 12 a rigid material, the probability of bending and breaking during prolonged operation is reduced, extending the equipment's lifespan.
