Description
Technical Field
[0001] This utility model relates to the field of agricultural product preservation technology, and in particular to agricultural product preservation and transportation boxes. Background Technology
[0002] Agricultural products refer to primary products derived from crop farming, forestry, animal husbandry, and fisheries. These include plants, animals, microorganisms, and their products obtained through agricultural activities. Agricultural products are a basic guarantee for human life and play an irreplaceable role in many areas such as food supply, nutrition intake, and industrial processing.
[0003] Agricultural products are characterized by their freshness and perishability. If left at room temperature for a short period of time, they will spoil, rot, and lose moisture, which will greatly affect their quality and economic value. Moreover, the production of agricultural products has obvious seasonality and regionality, while consumer demand for agricultural products is relatively stable and widely distributed. In order to achieve the conditions for fresh transportation of agricultural products to extend their shelf life and freshness, and to facilitate cross-seasonal and cross-regional circulation, refrigerated transport boxes have become the key to solving the problem of freshness of agricultural products during transportation and storage.
[0004] Currently, commercially available agricultural product preservation and transportation boxes generally consist of an outer shell and an insulation layer. The outer shell protects the agricultural products inside from external collisions, compression, and harsh weather conditions. The insulation layer, located inside the outer shell, reduces heat exchange between the inside and outside of the box, maintaining a relatively stable internal temperature. However, during use, the agricultural products loaded in the preservation and transportation box may be squeezed together. To solve this problem, existing technologies often use partitions to achieve layering. Since different types of agricultural products vary in size, this device cannot flexibly adjust and separate according to the shape and size of the agricultural products, resulting in wasted space, reduced practicality, and failure to meet user needs.

[0032] 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.
[0033] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of an agricultural product preservation and transportation box, including a box body 1. Multiple partitions 3 are equidistantly arranged inside the box body 1 to hold agricultural products. A cavity 6 is formed in the middle of the inner side of each partition 3. A connecting rod 8 is rotatably connected to the middle of the inner side of the cavity 6. A gear 7 is fixedly connected to the middle of the outer side of the connecting rod 8. Racks 9 are slidably connected to the front and rear sides of the cavity 6. Two racks 9 are respectively meshed with the front and rear sides of the gear 7. The movement of the rack 9 can drive the movement of the other rack 9 through the gear 7. A pull rod 4 is fixedly connected to the front wall of the front rack 9. A groove 5 is formed on the left side of the front wall of the partition 3. The front end of the pull rod 4 passes through the groove 5. Pulling the pull rod 4 can move the rack 9. A hollow rod 11 is fixedly connected to the rear left side of the cavity 6. A transmission rod 12 is slidably connected to the inner side of the hollow rod 11. The right end of the transmission rod 12 is connected to the rear rack 9. The hollow rod 11 is fixedly connected to a spring 10 on its outer side. One end of the spring 10 is fixedly connected to the left side of the cavity 6. The other ends of the multiple springs 10 are fixedly connected to one side of the corresponding rack 9. The transmission rod 12 and the hollow rod 11 are slidably connected to support the spring 10. Multiple first slots 13 are equidistantly opened on the left and right sides of the inside of the box 1. The far ends of the two racks 9 pass through the cavity 6 and engage with the corresponding first slots 13. The partition 3 can be adjusted up and down to fix its position. A folding mechanism 2 is provided on the bottom of the inside of the box 1. The folding mechanism 2 is used to facilitate the movement of the refrigerated transport box. The bottom left and right sides of the box 1 are fixedly connected to a locking block 19. The top left and right sides of the box 1 are provided with a second slot 18. The locking block 19 can engage with the second slot 18 and play a fixing role when the boxes 1 are stacked.
[0034] Specifically, the rack 9 on the front side inside the partition 3 can move laterally by pulling the lever 4. The gear 7 that meshes with the front and rear racks 9 plays a transmission role, enabling the front rack 9 to drive the rear rack 9 to move laterally. The part that passes through the partition 3 can disengage from the first slot 13 inside the housing 1. At the same time, the spring 10 connected to the rear rack 9 is compressed. The transmission rod 12 and the hollow rod 11 connected to the rear rack 9 play a supporting role in the spring 10. After the lever 4 is released, the spring 10 is freed from the compression force and then returns to its original position, pushing the rear rack 9 to drive the front rack 9 to move and re-engage with the first slot 13.
[0035] Reference Figure 2 and Figure 6The folding mechanism 2 includes a guide rod 204, which is rotatably connected to the lower right side of the housing 1. An inner cavity 208 is formed at the bottom of the housing 1. The left end of the guide rod 204 penetrates the housing 1, allowing external control of its rotation. Worms 201 are fixedly connected to the left and right sides of the outer wall of the guide rod 204. Rotating rods 203 are rotatably connected to the left and right sides of the inner cavity 208. Worm gears 202 are fixedly connected to the middle of the outer sides of both rotating rods 203. The two worms 201 are respectively connected to their corresponding worm gears. 202 meshing connection to achieve linkage. Rotating the guide rod 204 drives the rotating rod 203 to rotate. The outer wall of the rotating rod 203 is fixedly connected to the front and rear sides of the outer wall, and the bottom of the fixed rod 205 is fixedly connected to the wheel 206. The bottom of the box 1 has storage compartments 207 at the four corners, which can hide the wheel 206 in the storage compartments 207. The right end of the guide rod 204 is fixedly connected to the knob 17. The internal size of the storage compartment 207 matches the size of the wheel 206.
[0036] Specifically, the part of the guide rod 204 that extends through the housing 1 is connected to the knob 17. Rotating the knob 17 from the outside drives the guide rod 204 to rotate. The rotation of the guide rod 204 drives the worm gears 201 on both sides to rotate. The corresponding worm wheels 202 of the worm gears 201 on both sides mesh with them and drive the rotating rod 203 connected to the worm wheel 202 to rotate. Fixed rods 205 are connected to both sides of the rotating rod 203. The bottom of the fixed rod 205 is connected to the wheel 206. The rotation of the rotating rod 203 drives the wheel 206 to move at the same time, so that the wheel 206 can be retracted and extended by rotating the knob 17.
[0037] Reference Figure 1 , Figure 2 and Figure 3 Multiple cooling elements 15 are fixedly connected at equal intervals on the top inner side of the box 1. Multiple grooves 14 are equally spaced on the front and back sides of the top of the partition 3, which allows the heat emitted by the cooling elements 15 to circulate between the partitions 3. A controller 16 is fixedly connected to the upper right side of the box 1. The controller 16 is electrically connected to the cooling elements 15 and can control the temperature inside the box 1.
[0038] Specifically, the controller 16 operates by electrically controlling the cooling plate 15 on the top of the inner side of the housing 1, and adjusts the temperature inside the housing 1 as needed. The groove 14 opened in the partition 3 allows the temperature generated by the cooling plate 15 to flow throughout the entire housing 1 without being interrupted.
[0039] Reference Figure 1 The front side of the box body 1 is provided with a box door 23. The upper and lower sides of the left side of the front wall of the box door 23 are fixedly connected with hinges 21. The box door 23 is rotatably connected to the box body 1 through the hinges 21. The right side of the front wall of the box door 23 is fixedly connected with a handle 20 to facilitate opening the box door 23. An observation window 22 is provided in the middle of the front side of the box door 23.
[0040] Specifically, pulling the handle 20 causes the door 23 to rotate through the hinge 21 and the box body 1, thereby opening the door 23. The door 23 has an observation window 22, which allows for easy observation of the interior of the box body 1.
[0041] Working principle: When the partition 3 needs to be adjusted up and down, pull the lever 4 to the right to move the front rack 9 inside the partition 3. Both racks 9 inside the partition 3 mesh with the gear 7. When the front rack 9 moves, it drives the rear rack 9 to move and disengage from the first slot 13 inside the box 1. After the partition 3 is adjusted to the appropriate space, release the lever 4. The transmission rod 12 connected to the rear rack 9 and the hollow rod 11 slidably connected support the spring 10. The spring 10 rebounds and drives the racks 9 on both sides to reset and re-engage with the first slot 13 inside the box 1. The partition 3 can dynamically adjust the internal space of the box 1 according to the size of the agricultural products to avoid wasting space.
[0042] Furthermore, when the device needs to be moved, the guide rod 204 connected to it can be rotated by rotating the knob 17. When the guide rod 204 rotates, it drives the worm gears 201 on both sides to rotate. Since the worm gears 201 mesh with the worm wheel 202, the worm wheel 202 rotates synchronously and drives the connected rotating rod 203 to rotate. The rotating rod 203 can drive the connected fixed rod 205 to rotate. The rotation of the fixed rod 205 drives the wheel 206 connected to the bottom to move out of the storage compartment 207. When there is no need to move, rotating the knob 17 can put the wheel 206 back into the storage compartment 207. This can be selected as needed, making the box 1 more portable, saving manpower, and applicable to more scenarios.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
