Description

Technical Field

[0001] This utility model belongs to the field of cold chain transportation technology, and in particular relates to a cold chain transportation device. Background Technology

[0002] Cold chain transportation refers to a specialized logistics method that uses specific refrigeration technology and temperature control equipment to keep goods in a constant low-temperature environment throughout the entire process from production, warehousing, transportation to sales, in order to ensure the quality, safety, and freshness of perishable goods (such as fresh food, pharmaceuticals, and biological agents). It acts like a "mobile refrigerator," connecting every stage from source to end, and is a key support for modern logistics in ensuring product value.

[0003] Cold chain transportation is mainly achieved through several modes of transport, including refrigerated trucks, refrigerated railcars, refrigerated ships, refrigerated containers, and multimodal transport. Among these, road transport is flexible and convenient, suitable for short- and medium-distance delivery; refrigerated trucks are one of the most commonly used methods for cold chain transportation.

[0004] A prior art cold chain transportation anti-collision device disclosed in Chinese Patent (CN219192994U) includes a box body with multiple baffles inserted inside. Multiple springs are provided on the bottom wall of the box body, and spring seats are provided on the top of each spring. A base is provided on every two spring seats. A top seat is provided on the top of the box body. A lead screw is rotatably connected to the bottom wall of the top seat via a bearing. A circular plate is provided on the top of the lead screw, and multiple levers are provided on the outer wall of the circular plate. A connecting block is threaded onto the outer wall of the lead screw. Connecting rods are provided on the left and right outer walls of the connecting block. A rectangular block is provided on the connecting rod, and a sliding rod is provided at the bottom of the rectangular block. The bottom end of the sliding rod extends into the box body.

[0005] This method has the following drawbacks: First, while existing technologies place the refrigerated boxes stacked in the truck bed into a clamping mechanism to prevent them from shaking, this method puts the refrigerated boxes into another storage space, which occupies some of the space used for storing refrigerated boxes, reducing the effective space for cold chain transportation and lowering transportation efficiency. Second, in the process of using trucks for cold chain transportation, refrigerated boxes usually need to be stacked inside the truck bed for transport. The transportation method provided by the existing technology requires additional stacking of refrigerated boxes into the device and an extra layer of filling, which reduces loading and unloading efficiency. Third, although the device can fix the refrigerated boxes inside the truck bed to prevent impact damage, it occupies a large space when used for transportation, requiring a space for loading and unloading on site, which makes loading and unloading goods inconvenient.

[0006] Therefore, this utility model provides a cold chain transportation device. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model discloses a cold chain transportation device that saves transportation space inside refrigerated truck compartments and improves transportation efficiency. The folded-down fixing frame occupies little space and only requires a small area for storage during loading and unloading, improving the spatial convenience of loading and unloading operations. It eliminates the need for secondary loading and unloading after the refrigerated boxes are placed into the limiting device, ensuring work efficiency. Furthermore, the position of the fixing column can be freely adjusted according to the loading and unloading method, improving the device's applicability.

[0008] To achieve the above-mentioned technical effects, this utility model provides a cold chain transportation device, including a refrigerated compartment, a refrigerated box, and an auxiliary transportation mechanism. The auxiliary transportation mechanism is located inside the refrigerated compartment, and the refrigerated box is placed on the auxiliary transportation mechanism. The auxiliary transportation mechanism also includes a fixing frame and a blocking mechanism. A deformable and retractable fixing frame is provided at the bottom of the inner side of the refrigerated compartment, and adjustable blocking mechanisms are provided on the left and right sides of the inner side of the refrigerated compartment.

[0009] Preferably, the fixing frame further includes frame a, frame b, and rubber base, with frame a hinged to the front and rear sides of frame b respectively, and the rubber base respectively located below frame a and frame b.

[0010] Preferably, a rectangular elastic rubber pad is provided on the top of the frame a.

[0011] Preferably, a fixing rubber pad with side plates is provided above the frame b, and the top height of the fixing rubber pad is flush with the height of the elastic rubber pad.

[0012] Preferably, the blocking mechanism further includes a chute, a fixed post, a limiting mechanism, and a blocking strip. The chute is respectively located on the left and right sides of the inner side of the refrigerated compartment. The fixed post is respectively located on the inner side of the chute and is slidably connected to the chute. The limiting mechanism is located below the fixed post. The blocking strip is respectively located between the fixed posts. The left side of the blocking strip is fixedly mounted on the fixed post located on the left side, and the right side of the blocking strip is hooked to the hook of the fixed post located on the right side by a hook.

[0013] Preferably, the chute is provided with downward drainage grooves at both ends.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The device features a deformable, retractable frame and adjustable blocking mechanisms on both sides. The stacked refrigerated containers are secured by the frame at the bottom and the blocking straps on the sides. After unloading, the frame and blocking straps can be retracted, saving space inside the refrigerated truck and improving transport efficiency. The retracted frame occupies minimal space, requiring only a small area for loading and unloading, enhancing spatial convenience. Using this solution, loading and unloading refrigerated containers only requires setting up the frame and then pulling the blocking straps to secure them; a second loading / unloading is unnecessary after inserting the container into the limiting device, ensuring efficiency.

Detailed Implementation

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0019] like Figures 1 to 7 As shown The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: First, the existing storage method occupies a portion of the space used for storing refrigerated boxes, reducing the effective space for cold chain transportation and reducing transportation efficiency; Second, the transportation method provided in the prior art requires additional stacking of refrigerated boxes into the device and an extra layer of filling process, which reduces loading and unloading efficiency; Third, the device occupies a large area, requiring a space for loading and unloading on site, which makes loading and unloading goods inconvenient. Therefore, the inventor provides a cold chain transportation device, including a refrigerated compartment 1, a refrigerated box 2, and an auxiliary transportation mechanism. The auxiliary transportation mechanism is located inside the refrigerated compartment 1, and the refrigerated box 2 is placed on the auxiliary transportation mechanism. The auxiliary transportation mechanism also includes a fixing frame 3 and a blocking mechanism 4. The bottom of the inner side of the refrigerated compartment 1 is provided with a deformable and retractable fixing frame 3, and the left and right sides of the inner side of the refrigerated compartment 1 are provided with adjustable blocking mechanisms 4.

[0020] Using the above method, before loading the goods, the loading and unloading workers unfold the fixing frame 3 and place it at the bottom of the inner side of the refrigerated compartment 1. Set up the fixing frame 3 for the required layer, set the blocking mechanism 4 in front of the fixing frame 3, and then place the refrigerated box 2 on top of the fixing frame 3. The fixing frame 3 is used to fix the left and right sides of the refrigerated box 2 to reduce shaking during transportation. After placing one layer of refrigerated box 2, use the blocking mechanism 4 to fix the front of the refrigerated box 2. Follow the above steps to stack and fix the refrigerated boxes 2 from the inside to the outside and from the bottom to the top in sequence to complete the loading of the goods. During unloading, open the barrier mechanism 4 in the order from top to bottom and from outside to inside, remove the refrigerated boxes 2 on the fixed frame 3, and after removing the refrigerated boxes 2 of each layer, fold up the fixed frame 3 at the bottom for recycling. Follow the above steps to unload the refrigerated boxes 2 in the refrigerated compartment 1 to complete the unloading. Example 2

[0021] like Figures 1 to 7 As shown Furthermore, the fixed frame 3 also includes frame a5, frame b6, and rubber base 7. Frame a5 is hinged to the front and rear sides of frame b6 respectively, and rubber base 7 is respectively located below frame a5 and frame b6. Furthermore, a rectangular elastic rubber pad 8 is provided above the frame a5; Furthermore, a fixed rubber pad 9 with side plates is provided above the frame b6, and the top height of the fixed rubber pad 9 is flush with the height of the elastic rubber pad 8. In the folded state, frames a5 and b6 are hinged together and folded inwards, placed in the working area outside the refrigerated compartment 1. When the refrigerated box 2 is being packed, the fixing frame 3 is unfolded and placed at the bottom inside the refrigerated compartment 1. The rubber base 7 below the fixing frame 3 increases the friction between the fixing frame 3 and the inner wall of the compartment, preventing the refrigerated box 2 from moving inside the compartment during transportation. After the fixing frames 3 are placed, each layer of fixing frames 3 fits together, so that the bases of the fixing frames 3 are in contact and connected together. During transportation, they share the friction generated by the bumps of the truck at the bottom, maintaining the stability of the overall refrigerated box 2 and reducing the shaking of the goods inside the refrigerated box 2. The refrigerated box 2 is placed above the fixing rubber pad 9 of frame b6 and between the side panels of the fixing rubber pad 9. The fixing rubber pad 9 and the elastic rubber pad 8 provide support and elastic cushioning for the refrigerated box 2 at the bottom, reducing the vibration of the refrigerated box 2 during transportation. The above solution can provide fixed support for the refrigerated boxes 2 stacked inside the refrigerated compartment 1, while reducing the vibration of the goods inside the refrigerated boxes 2. The fixing frame 3 can be directly removed and stored during unloading, saving transportation space inside the refrigerated compartment 1 and improving transportation efficiency. The fixed frame 3 occupies little space overall and only requires a small area in the loading and unloading space, which improves the spatial convenience of loading and unloading work. Example 3

[0022] like Figures 1 to 7 As shown Furthermore, the blocking mechanism 4 also includes a chute 10, a fixed post 11, a limiting mechanism 12, and a blocking strip 13. The chute 10 is respectively located on the left and right sides of the inner side of the refrigerated compartment 1. The fixed post 11 is respectively located on the inner side of the chute 10 and is slidably connected to the chute 10. The limiting mechanism 12 is located below the fixed post 11. The blocking strip 13 is respectively located between the fixed posts 11. The left side of the blocking strip 13 is fixedly located on the fixed post 11 on the left side, and the right side of the blocking strip 13 is hooked to the hook of the fixed post 11 on the right side by a hook. Furthermore, downward drainage channels 14 are provided at both the front and rear ends of the chute 10; Furthermore, the limiting mechanism 12 also includes a limiting spring 15, a slider 16, a pull rod 17, a fixed wheel 18, and a gear tooth 19. The limiting spring 15 is disposed above the slider 16, the slider 16 is disposed in the space at the lower end of the fixed post 11, the fixed wheel 18 is disposed below the pull rod 17, the left and right sides of the fixed wheel 18 are slidably connected to the fixed post 11, the lower part of the fixed wheel 18 is provided with a gear tooth 19, the fixed post 11 on the front side of the slider 16 is provided with an opening, the front end of the slider 16 passes through the opening to the outside of the fixed post 11, and the pull rod 17 is disposed at the front end of the slider 16 located outside the fixed post 11. Furthermore, a limiting strip 20 is provided on the refrigerated compartment 1 below the fixed column 11; In the fixed state, the limiting mechanism 12 below the fixed column 11 fixes the fixed column 11 to the slide groove 10. The limiting spring 15 presses down the slider 16 with elastic force, so that the wheel teeth 19 below the slider 16 are in contact with the limiting rubber strip 20. In this way, the limiting spring 15 drives the wheel teeth 19 to engage with the limiting rubber strip 20, so that the fixed column 11 remains stationary during transportation. When it is necessary to move the fixed post 11, pull the slider 16 upward by pulling the lever 17, so that the gear teeth 19 are lifted off the limiting rubber strip 20, releasing the limitation on the fixed post 11. Then move the fixed post 11 on the slide groove 10 to adjust its position. After the adjustment is completed, lower the lever 17, and the gear teeth 19 re-engage on the limiting rubber strip 20 to complete the fixation. When a layer of goods is stacked on the fixing frame 3 between the fixed posts 11, the barrier straps 13 at the corresponding positions of the layer are stretched and fastened to the fixed posts 11 on the opposite side. The taut barrier straps 13 are used to block the refrigerated boxes 2 of the layer from the front and back. The upward limiting and fixing prevents the refrigerated box 2 from shaking in the front and back direction during transportation. The barrier belt 13 is made of high elastic rubber belt. When relaxed, it hangs naturally on the fixing post 11 on the left side. When fixed, it is stretched and tightened between the fixing posts 11. In this way, the refrigerated box 2 on each layer of the fixing frame 3 is restricted from the front and back sides, reducing the shaking of the refrigerated box 2 caused by the bumps of the refrigerated compartment 1 during transportation. With this method, the device can be stored on both sides inside the compartment, ensuring the fixing function while facilitating storage and saving space inside the compartment. When the cargo compartment contains two or more different goods, the loading and unloading workers can stack the same type of goods together and use two sets of blocking mechanisms 4 to fix the goods from the front and rear sides. Since there are no limiting side plates on the elastic rubber pads 8 on the frame a5 of the fixing frame 3, the refrigerated boxes 2 in the front and rear directions can be connected together to improve the stability of the stacked refrigerated boxes 2. The position of the side fixing column 11 can be freely adjusted. Therefore, when the refrigerated boxes 2 cannot be stacked to fill a whole layer, the position of the fixing column 11 can be pulled in and the blocking strip 13 can be tightened inward to fix the extra refrigerated boxes 2. During the transfer process, the moisture inside the refrigerated compartment 1 will condense into the inside of the chute 10 to form an ice layer. This ice layer will always melt during the unloading process, causing water to accumulate inside the chute 10. If this water is not drained in time, it will form a thicker block of ice inside the chute 10 during the next transfer, causing the fixing column 11 to be frozen and unable to move. Therefore, drainage channels 14 are set at both ends of the chute 10 to drain the water inside the chute 10 in time.

[0023] In summary, this device features a deformable and retractable fixed frame 3 and adjustable blocking mechanisms 4 on both sides. The fixed frame 3 at the bottom of the refrigerated container 2 and the blocking straps 13 on the sides of the refrigerated container 2 secure the stacked containers. After unloading, the fixed frame 3 and blocking straps 13 can be retracted, saving transport space inside the refrigerated truck compartment 1 and improving transport efficiency. The retracted fixed frame 3 occupies little space overall, requiring only a small area for storage during loading and unloading, thus improving the spatial convenience of loading and unloading operations. Using this solution, loading and unloading the refrigerated container 2 only requires setting up the fixed frame 3 and then pulling the blocking straps 13 to secure it. There is no need for secondary loading and unloading after inserting the refrigerated container 2 into the limiting device, ensuring work efficiency. Furthermore, the position of the fixed column 11 can be freely adjusted according to the loading and unloading method, improving the device's applicability.

[0024] The working principle of this utility model: Before loading the goods, the loading and unloading workers unfold the fixing frame 3 and place it on the bottom of the inner side of the refrigerated compartment 1. They set up the fixing frame 3 for the layer to be placed. Then, they adjust the fixing post 11 according to the position of the fixing frame 3. They pull the slider 16 upward by the pull rod 17, so that the wheel tooth 19 is lifted off the limiting rubber strip 20, releasing the limitation on the fixing post 11. Then, they move the fixing post 11 on the slide 10 to adjust its position. After the adjustment is completed, they lower the pull rod 17, and the wheel tooth 19 re-engages on the limiting rubber strip 20 to complete the fixing. After a layer of goods is stacked on the fixed frame 3 between the fixed posts 11, the barrier strap 13 at the corresponding position of the layer is stretched and fastened to the fixed post 11 on the opposite side. The taut barrier strap 13 is used to limit and fix the refrigerated box 2 of the layer in the front and back direction to prevent the refrigerated box 2 from shaking in the front and back direction during transportation. The barrier strap 13 is made of high elastic rubber belt. When relaxed, it hangs naturally on the fixed post 11 on the left side. When fixed, it is stretched and tightened between the fixed posts 11. In this way, the refrigerated box 2 of each layer on the fixed frame 3 is restricted from the front and back sides, reducing the shaking of the refrigerated box 2 caused by the bumps of the refrigerated compartment 1 during transportation. In this way, the device can be stored on both sides inside the compartment, ensuring the fixing function while facilitating storage and saving space inside the compartment. After the fixed frame 3 is placed, the fixed frames 3 of each layer fit together, so that the bases of the fixed frames 3 are connected together. During transportation, they share the friction force generated by the bumps of the truck at the bottom, maintain the stability of the overall refrigerated box 2, and reduce the shaking of the goods inside the refrigerated box 2. The refrigerated box 2 is placed on top of the fixed rubber pad 9 of the frame b6 and between the side panels of the fixed rubber pad 9. The fixed rubber pad 9 and the elastic rubber pad 8 provide support and elastic cushioning for the refrigerated box 2 at the bottom of the refrigerated box 2, reducing the vibration of the refrigerated box 2 during transportation. The above solution can provide fixed support for the refrigerated boxes 2 stacked inside the refrigerated compartment 1, while reducing the vibration of the goods inside the refrigerated boxes 2. The fixed frame 3 can be directly removed and stored during unloading, saving transportation space inside the refrigerated compartment 1 and improving transportation efficiency. The fixed frame 3 occupies little space overall and only needs a small area in the loading and unloading space, which improves the spatial convenience of loading and unloading work. By following the above steps, the refrigerated boxes 2 are stacked layer by layer inside the refrigerated compartment 1; When the compartment contains two or more different goods, the loading and unloading workers can stack the same type of goods together and use two sets of blocking mechanisms 4 to fix the goods from the front and rear sides. Since there are no limiting side plates on the elastic rubber pads 8 on the frame a5 of the fixing frame 3, the refrigerated boxes 2 in the front and rear directions can be connected together to improve the stability of the stacked refrigerated boxes 2. During unloading, open the barrier mechanism 4 in the order from top to bottom and from outside to inside, remove the refrigerated boxes 2 on the fixed frame 3, and after removing the refrigerated boxes 2 of each layer, fold up the fixed frame 3 at the bottom for recycling. Follow the above steps to unload the refrigerated boxes 2 in the refrigerated compartment 1 to complete the unloading. This concludes the description of the working principle of the device.
