It has a wide range of applications, such as cold chain logistics for food, transportation of pharmaceuticals, constant temperature transportation of industrial and scientific research samples, and fresh food retail and warehousing.

[0003] Patent CN201921767878.2 discloses a partitionable refrigerated truck compartment, including a cab and a compartment. Two vertical partitions are fixed inside the compartment, dividing the interior into three identical storage zones. From left to right, these zones are a low-temperature zone, a medium-temperature zone, and a high-temperature zone. Sealed doors are provided on the same side surface of each of the three zones. A refrigeration unit is installed at the top of the compartment near the cab, and a cooling fan is installed on the inner wall of the top of the low-temperature zone, connected to the refrigeration unit via pipes. This device uses partitions to divide the interior into several different temperature zones, meeting the storage needs of multiple temperature zones. However, to facilitate access to items within each zone, doors need to be opened from the side of the compartment. Therefore, not only do the partitions require new production lines, but the compartment itself also requires new production lines. Furthermore, increasing the number of doors increases the probability of cold air leakage and places higher demands on the sealing of the compartment. Additionally, the uneven weight distribution on the left and right sides of the compartment can affect the vehicle's balance to some extent. Utility Model Content

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figures 1-7As shown, this utility model provides a multi-temperature box with front and rear sealable partitions, including a box body 1. A refrigeration unit 2 and a door 3 are respectively arranged on the front and rear sides of the box body 1. Two sets of partition components 4 are arranged inside the box body 1, with a cooling fan 5 and an exhaust window 6 mounted on each partition component 4. The two partition components 4 divide the interior of the box body 1 into three temperature zones: front, middle, and rear. The refrigeration unit 2 provides cooling to the front temperature zone, while the cooling fan 5 distributes cooling to the middle and rear temperature zones, thus forming storage temperature zones with different temperatures and a certain spatial size. Based on this, the partition component 4 provided by this utility model includes a flip partition 41 and a hook partition 42 that is engaged with the flip partition 41. The top of the flip partition 41 is provided with at least two ball hinges 43. The top of the ball hinges 43 is provided with a fixing groove plate 44. The bottom of the fixing groove plate 44 is provided with a lifting sealing plate 45. The lifting sealing plate 45 has an inverted T-shaped structure and its upper half is in sealing contact with the inner side of the fixing groove plate 44. The top of the flip partition 41 has a regular T-shaped structure and is located below the lifting sealing plate 45.

[0026] Specifically, this utility model does not provide a door on the side of the box 1, but only requires the installation of the partition component 4 at the corresponding position inside the box 1. Therefore, the original production line of the box 1 can be maintained, and only the production line of the partition component 4 needs to be added. For the partition component 4, the fixed groove plate 44 is used as the installation base. The fixed groove plate 44 can be welded to the box 1 or fixed to the inner top of the box 1 with screws. The lifting sealing plate 45 below the fixed groove plate 44 is used to form a relatively sealed combination with the fixed groove plate 44 and the flip partition 41. On the other hand, it can leave sufficient flipping margin for the top of the flip partition 41 to avoid the flip partition 41 getting stuck during the flipping process around the ball hinge 43. Furthermore, the flip-up partition 41 and the hanging partition 42 can form a partition component 4 that is sealed on all four sides (top, bottom, left, and right). Removing the hanging partition 42 from the flip-up partition 41 and flipping up the flip-up partition 41 allows for the placement and removal of items in different temperature zones without needing a side door on the cabinet 1. For the flip-up partition 41, one side of the plate corresponding to the ball hinge 43 is a blocking surface, while the other side provides a reasonable opening for the ball hinge 43. Since the flip-up partition 41 is an insulated plate, it has a certain thickness. During the flipping process, the diameter from its top to the rotation center of the ball hinge 43 is certain. Therefore, the flip-up partition... After the partition plate 41 flips, it can lift the lifting sealing plate 45 to a certain height, providing sufficient radius margin for its flipping. After the partition plate 41 flips into place, the lifting sealing plate 45 can rest on the top of the ball head 432 of the ball hinge 43. During the action of the partition plate 41 flipping down, the top edge of the partition plate 41 can abut against the side of the sealing plate, lifting the sealing plate along the side of the sealing plate until the partition plate 41 falls completely. The top of the partition plate 41 is attached to the bottom surface of the lifting sealing plate 45. With the nesting effect of the fixing groove plate 44, the top of the partition plate 41 returns to the original sealing conditions. Therefore, the partition component 4 can ensure good sealing at its flipping node position while ensuring its effective flipping ability, so as to ensure the relative sealing of adjacent temperature zones.

[0027] To improve the cooperation performance between the ball hinge 43 and the fixed slot plate 44, the lifting sealing plate 45, and the flip partition 41, the ball hinge 43 provided by this utility model includes a fixed rod 431 connected to the fixed slot plate 44, a ball head 432 at the bottom of the fixed rod 431, and a ball sleeve 433 disposed on the flip partition 41. The ball sleeve 433 has a U-shaped opening 434 on its side that engages with the fixed rod 431 during flipping. The fixed rod 431 provides a lifting guide for the lifting sealing plate 45, and the ball head 432 prevents the lifting sealing plate 45 from detaching from the ball hinge 43. The ball head 432 and the ball sleeve 433 have spherical rotating surfaces. During the flipping process of the flip partition 41 around the ball head 432, the U-shaped opening 434 prevents the flip partition 41 from being stuck to one side of the fixed rod 431, thus ensuring that the flip partition 41 has an effective flipping height. For easy access to items, such as... Figure 1 As shown, several positioning protrusions can be welded onto the box body 1. If the flip partition 41 is flipped over the positioning protrusions, it can prevent it from falling freely. Alternatively, a second person can prop up the flip partition 41 so that others can take or put items.

[0028] To ensure the opening and closing performance of the flip-up partition 41, the top of the lifting sealing plate 45 provided by this utility model is provided with a through hole 451 that moves vertically and vertically with the fixing rod 431. The inner two walls of the lifting sealing plate 45 are provided with V-shaped inner inclined surfaces 452, and the outer two walls of the lifting sealing plate 45 are provided with V-shaped outer inclined surfaces 453. The through hole 451 allows the lifting sealing plate 45 to move up and down reasonably as the flip-up partition 41 flips. Furthermore, the outer inclined surfaces 453 and inner inclined surfaces 452, under the action of the top edge of the flip-up partition 41 abutting against each other, cause the lifting sealing plate 45 to have a lifting tendency, preventing the flip-up partition 41 from being stuck at the flipped angle, thereby ensuring the opening and closing performance of the flip-up partition 41.

[0029] To ensure the sealing performance at both ends of the lifting sealing section, this utility model provides sealing gaskets at both ends of the lifting sealing plate 45, which can play a certain sealing role.

[0030] To improve the fit between the hanging partition 42 and the flip partition 41, this invention provides a pair of positioning frames 411 on the flip partition, which nest with the positioning openings 421 on the hanging partition 42. Through the nesting of the positioning frames 411 and the positioning openings 421, the flip partition 41 and the hanging partition 42 can obtain support and locking forces in multiple directions, which helps improve the stability of the hanging partition 42, and also provides better quick disassembly and assembly, making it highly practical.

[0031] Furthermore, the positioning frame 411 provided by this utility model has a break 412 at its bottom, and the positioning port 421 has a protrusion 422 at its bottom that cooperates with the break 412. The break 412 allows the positioning frame 411 to have a small elastic deformation allowance, which facilitates the hanging action of the hanging partition 42. Moreover, after the hanging partition 42 is fixed on the flip partition 41, the protrusion 422 supports the break 412, thereby improving the reliability of the combination of the hanging partition 42 and the flip partition 41.

[0032] To improve the sealing performance of the hanging partition 42 and the flip partition 41 at the joint, the flip partition 41 provided by this utility model is provided with a front adhesive section 413 at the bottom, and the hanging partition 42 is provided with a rear adhesive section 423 that fits tightly with the front adhesive section 413. The front adhesive section 413 and the rear adhesive section 423 form a folded sealing surface at the joint, which helps to improve the reliability and sealing performance of the hanging partition 42 and the flip partition 41 after assembly.

[0033] like Figure 1 , Figure 3 and Figure 4 To prevent the hanging partition 42 from flipping, this utility model provides a T-shaped base plate at the bottom of the hanging partition 42. The base plate can be connected to the partition with screws. The bottom surface of the base plate increases the span of the hanging partition 42 in the front-to-back direction, thus preventing the hanging partition 42 from flipping and affecting the stability of the flipping partition 41.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
