Description

Technical Field

[0001] This utility model relates to the technical field of foldable multi-layer food transport packaging boxes, specifically a foldable multi-layer food transport packaging box. Background Technology

[0002] Food transport packaging boxes are containers specifically designed for transporting food, aiming to protect the safety and quality of food during transportation. However, existing devices still have some shortcomings; for example;

[0003] For example, a food transport packaging box with announcement number CN221189647U, when used technically, includes a box body with a hinged door on one side. The box body contains a food tray assembly for storing food. A partition is rotatably mounted on the top of the box body near the door. Sealing assemblies are symmetrically arranged on the inner wall of the box. Locking assemblies for locking or releasing the partition are symmetrically arranged inside the box body near the door. By placing food on the tray, making it adhere to the top wall of the box, and then inserting the tray from one side of the tray groove, the sealing plate is compressed, thereby compressing a spring placed along the tray groove at the innermost part of the box body. By observing whether the sealing plate is reset, it can be determined whether the pallet slot should be placed at the innermost part of the box to improve the utilization rate of the internal space of the box. When the innermost part of the box is full, the pallet is then placed on the outer side of the box to maximize the storage of frozen food in the box and improve the practicality of the equipment. Although this device can be well applied to complete the storage of food during transportation, the current food transportation process requires the use of multiple packaging boxes, which take up a lot of space and are inconvenient to store and transport. Therefore, we propose a foldable multi-layer food transportation packaging box device to solve the above-mentioned problems. Utility Model Content

The bottom of the outer side of the front plate is provided with a locking block that cooperates with the stop block.

[0008] As a preferred technical solution of this utility model, the layered component includes a partition, a middle plate, outer layer plates, an assembly groove, and an assembly slider. The partition is provided with an assembly groove on both sides, and the inner sides of the outer layer plates on both sides of the middle plate are provided with assembly sliders that cooperate with the assembly grooves. The two sets of partitions are arranged vertically and parallel, and are slidably spliced ​​together by the middle plate. The two sets of outer layer plates are slidably assembled on the outer sides of the two sets of partitions respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The foldable multi-layer food transport packaging box is equipped with a folding mechanism. When the box needs to be folded and stored after use, first pull the handles inside the two side covers above the top plate, and then pull the covers to the sides. This causes the locking blocks on the surface of the sinking groove at the front of the cover to disengage from the locking grooves inside the splicing plate. After opening the cover, the internal layered components can be taken out. At this time, push the front plates on both sides, so that the lower part of the front plate disengages from the locking components and fixing blocks. Then, with the help of the hinge shaft, the front plates are retracted into the interior. At this time, push the lower and upper side plates on both sides, so that the lower and upper side plates fold inward, and the top plate position is lowered. At this time, the top plate and the base are brought closer together, completing the folding of the box. Then, insert the limiting holes on the surfaces of the partition, middle plate and outer layered plates into the limiting rod above the top plate, and rotate the fixing frame onto the limiting rod for fixing. This completes the collection of the internal layered components during folding. Attached Figure Description

[0021] Please see Figure 1-5 This utility model provides a technical solution: a foldable multi-layer food transport packaging box, including a base 1 and a top plate 2 connected above by a folding assembly 3. The folding assembly 3 includes a lower side plate 301, an upper side plate 302, and a front plate 303. Two sets of lower side plates 301 are provided above the base 1, and the lower ends of the two sets of lower side plates 301 are hinged to the base 1. An upper side plate 302 is provided above the lower side plates 301, and the top of the lower side plates 301 and the bottom of the upper side plates 302 are hinged. The upper end of the upper side plate 302 is hinged to the top plate 2. Two sets of front plates 303 are hinged below the top plate 2. The front plates 303 are connected to the base 1 below by a locking assembly 6. The locking assembly 6 includes a fixing block 10, a locking block 603, a stop block 602, and a spring 601.

One end of the spring group 601 is fixedly connected to the inside of the fixing block 10. The other end of the two spring groups 601 is provided with a stop block 602. The bottom of the outer side of the front plate 303 is provided with a locking block 603 that cooperates with the stop block 602. The top plate 2 is provided with two sets of cover plates 4. The sides of the two sets of cover plates 4 are hinged to the top plate 2. The other side of the two sets of cover plates 4 is provided with a settling groove 11. The middle of the top of the cover plate 4 is provided with a handle for pulling. The middle of the top of the middle plate 702 is provided with a handle for pulling out the middle plate 702. The thickness of the settling groove 11 is half that of the cover plate 4. The upper surface of the settling groove 11 is provided with a splicing plate 12. The upper surface of the settling groove 11 is provided with three sets of splicing plates 12. The surface of the splicing plate 12 is provided with multiple locking blocks 5. The locking blocks 5 are of different sizes. The multiple splicing plates 12 are provided with locking blocks 5. The bottom of the splicing plate 12 is provided with a locking groove that cooperates with the locking blocks 5.

[0022] When the box needs to be folded for storage after use, first pull the handles inside the two side covers 4 above the top plate 2, then pull the covers 4 to the sides, causing the locking block 5 on the surface of the sink groove 11 at the front of the cover 4 to disengage from the locking groove inside the splicing plate 12. Next, open the cover 4 and remove the internal middle plate 702, outer layer plate 703, and partition plate 701. At this time, push the front plates 303 on both sides, causing the locking block 603 below the front plate 303 to disengage from the stop block 602 connected by the spring 601 inside the fixing block 10 above the base 1. At this time, the front plate 303 can be adjusted by the hinge shaft, allowing the front plate 303 to retract inside. Next, push the lower side plate 301 and upper side plate 302 on both sides to fold the lower side plate 301 and upper side plate 302 inward, and the top plate 2 will descend. At this time, the top plate 2 and the base 1 will move closer to each other, completing the folding of the box. Then, insert the limiting holes on the surface of the partition plate 701, the middle plate 702 and the outer layer plate 703 into the limiting rod 8 above the top plate 2, and rotate the fixing piece 9 onto the limiting rod 8 for fixing, thus completing the collection of the internal layered components during folding.

[0023] A layering component 7 for storing food in layers is provided above the base 1. The layering component 7 includes a partition 701, a middle plate 702, outer layer plates 703, an assembly groove 704, and an assembly slider 705. The partition 701 has an assembly groove 704 on both sides. The inner sides of the outer layer plates 703 on both sides of the middle plate 702 have assembly sliders 705 that cooperate with the assembly grooves 704. The two sets of partitions 701 are arranged vertically and parallel, and are slidably spliced ​​together by the middle plate 702. The two sets of outer layer plates 703 are slidably assembled on the outer sides of the two sets of partitions 701 respectively. A limit rod 8 is provided above the top plate 2. A fixing part 9 is provided above the limit rod 8. The fixing part 9 and the limit rod 8 are threadedly connected. The surfaces of the middle plate 702 and the partition 701 are provided with limit holes corresponding to the limit rod 8. The base 1 has two sets of assembly grooves inside, and the two sets of assembly grooves cooperate with the partitions 701.

[0024] In use, after inserting the partition 701 into the base 1, food can be stored in the lower half of the box. Next, the middle plate 702 is assembled using the mounting sliders 705 on both sides in conjunction with the mounting grooves 704 inside the partition 701. Then, the outer layer plates 703 on both sides are assembled using the mounting sliders 705 in conjunction with the mounting grooves 704 inside the partition 701, completing the layering of the box's interior. At this point, food can be stored in the upper half of the box, completing the layered storage of food.

[0025] Working Principle: When using the foldable multi-layer food transport packaging box, insert the partition 701 into the base 1 to store food in the lower half of the box. Next, assemble the middle plate 702 using the assembly sliders 705 on both sides in conjunction with the assembly grooves 704 inside the partition 701. Then, assemble the outer layer plates 703 on both sides using the assembly sliders 705 in conjunction with the assembly grooves 704 inside the partition 701, completing the layering of the box interior. Food can then be stored in the upper half of the box interior, achieving layered food storage. When folding the box after use, first pull the handles inside the two side covers 4 above the top plate 2, then pull the covers 4 to the sides, causing the locking blocks 5 on the surface of the sink groove 11 at the front of the cover 4 to disengage from the locking grooves inside the splicing plate 12. Then, open the covers 4 and remove the middle plate 702, outer layer plates 703, and partition 701. At this point, pushing the front panels 303 on both sides disengages the locking block 603 below the front panel 303 and the stop block 602 connected by the spring 601 inside the fixing block 10 above the base 1. The front panel 303 is then adjusted via the hinge shaft, retracting into the interior. Next, pushing the lower side panels 301 and upper side panels 302 on both sides causes them to fold inwards, lowering the top panel 2. The top panel 2 and base 1 then move closer together, completing the folding of the housing. Next, the limiting holes on the surfaces of the partition 701, middle panel 702, and outer layer panel 703 are inserted into the limiting rod 8 above the top panel 2. The fixing member 9 is then rotated onto the limiting rod 8 for fixation, completing the collection of the internal layered components during folding. All of this is done in a series of steps.
