Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a foldable cold chain logistics packaging box. Background Art

[0002] The packaging box is light in material and heavy in load-bearing capacity. It can be customized according to the size and specifications of the goods, and is mainly used to replace wooden boxes for transportation. It is fast to assemble, saves time and labor, has exquisite craftsmanship, good sealing performance, and can save a lot of wood resources. It is an internationally recognized and promoted new environmentally friendly packaging product. Honeycomb carton series products are not only resistant to extrusion, anti-buffering, and strong shockproof.

[0003] Existing packaging boxes are often not easy to fold during use, which often takes up a lot of space during storage, resulting in a limited storage quantity. In addition, for some low-temperature transported goods, a certain amount of ice packs are often required to be stored inside to ensure that the goods can still maintain a low temperature when transported to the designated location, but ice packs often take up a lot of space. Utility Model Content

[0004] The purpose of the utility model is to provide a foldable cold chain logistics packaging box to overcome the above-mentioned defects in the prior art.

[0005] According to the utility model, a foldable cold chain logistics packaging box includes a main box body, and two groups of positioning frames are fixedly provided with left-right symmetrical positioning frames on the upper end surface of the main box body. The front and rear end surfaces of the positioning frames respectively rotate fan blade rotating shafts, and the outer circular surface of the rotating shaft is fixedly provided with a rotating frame. A swing cavity with an opening upward and connected to the outside world is provided in the main box body, and two groups of swing shafts with front-back symmetry are rotatably provided between the left and right walls of the swing cavity. A swing frame is fixedly provided on the outer circular surface of the swing shaft, so that the swing frame and the rotating frame have a folding function, and a storage rack that can move forward and backward is provided in the main box body, and a storage cavity with an opening upward is provided in the storage rack, so that the storage cavity plays a storage role.

[0006] In some embodiments, a rotating motor is fixedly disposed in the positioning frame, and an end surface of one side of the rotating shaft close to the symmetry center is dynamically connected to the rotating motor.

[0007] In some embodiments, a swing motor is fixedly provided in the right wall of the swing cavity, and the right end surface of the swing shaft is dynamically connected to the swing motor.

[0008] In some embodiments, a power cavity connected to the outside is provided in the rotating frame, a cover frame is rotatably provided in the power cavity, and the cover frame serves to cover the swing cavity, and a handle is fixedly provided on the end face of the cover frame away from the symmetry center.

[0009] In some embodiments, a filter plate is fixedly provided on the lower wall of the swing chamber, left and right sides of the main box body are fixedly provided with left-right symmetrical threaded sliders, and screws are rotatably provided on the left and right sides of the storage rack and penetrate the storage rack, and the screws are threadedly matched with the threaded sliders.

[0010] In some embodiments, a controller is fixedly provided on the rear end surface of the main box body, and the controller plays a coordinating role in regulating various movements.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] 1. The utility model starts by two sets of swing motors that are symmetrical in front and back, thereby driving the swing shaft and the swing frame to rotate in symmetrical directions. When the inner end surface of the swing frame is kept horizontal with the filter plate, the swing motor is turned off, and then the left-right symmetrical rotating motor starts, thereby driving the two sets of rotating shafts that are symmetrical in front and back and the rotating frame to start rotating in mutually symmetrical directions. When the symmetrical end surfaces of the rotating frame are kept horizontal with the upper end surface of the swing frame, the rotating motor is turned off. At the same time, the cover frame starts to swing toward the upper end surface of the rotating frame, thereby ensuring that the rotating frame, the cover frame and the swing frame are folded, thereby ensuring that the occupied space can be reduced during storage, thereby ensuring that the box can be switched at any time when in use and not in use, thereby ensuring the practicality and flexibility of the packaging box.

[0013] 2. The utility model starts to rotate by rotating two groups of screws that are symmetrical on the left and right. At this time, due to the threaded cooperation between the screws and the threaded slider, when the screws are away from the threaded slider, the user can directly pull out the storage rack, put the ice bag into the storage cavity, push the storage rack into the main box, and then tighten the screws, thereby ensuring the realization of autonomous heat preservation, so that the heat preservation can continue when delivered to the destination, and changing the existing packaging box. When the ice bag takes up a lot of space, it ensures the space for storing goods and further ensures the practicality of the packaging box. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A rotating motor 12 is fixedly disposed in the positioning frame 28 , and an end surface of one side of the rotating shaft 13 close to the symmetry center is dynamically connected to the rotating motor 12 .

[0027] A swing motor 17 is fixedly disposed in the right wall of the swing chamber 15 , and the right end surface of the swing shaft 16 is dynamically connected to the swing motor 17 .

[0028] The rotating frame 14 is provided with a power cavity 26 connected to the outside, and a cover frame 19 is rotatably provided in the power cavity 26, so that the cover frame 19 plays the role of covering the swing cavity 15, and a handle 27 is fixedly provided on the end face of the cover frame 19 away from the symmetry center.

[0029] A filter plate 24 is fixedly provided on the lower wall of the swing chamber 15, and left and right symmetrical threaded sliders 20 are fixedly provided on the left and right sides of the main box body 11. Screws 21 are rotatably provided on the left and right sides of the storage rack 22 and penetrate the storage rack 22. The screws 21 are threadably matched with the threaded sliders 20.

[0030] A controller 25 is fixedly disposed on the rear end surface of the main box body 11, and the controller 25 plays a role in regulating various movements.

[0031] Specific workflow:

[0032] When folding, the two groups of swing motors 17 that are symmetrical in front and back start to start, thereby driving the swing shaft 16 and the swing frame 18 to rotate in a symmetrical direction. When the inner end surface of the swing frame 18 is kept horizontal with the filter plate 24, the swing motor 17 is turned off. At this time, the left-right symmetrical rotating motor 12 starts to start, thereby driving the two groups of rotating shafts 13 that are symmetrical in front and back and the rotating frame 14 to start rotating in mutually symmetrical directions. At this time, the symmetrical end surface of the rotating frame 14 is kept horizontal with the upper end surface of the swing frame 18, and the rotating motor 12 is turned off. At the same time, the cover frame 19 starts to swing toward the upper end surface of the rotating frame 14, thereby ensuring that the rotating frame 14, the cover frame 19, and the swing frame 18 are folded.

[0033] When in use, the two groups of left and right symmetrical screws 21 start to rotate. Since the screws 21 are threadedly matched with the threaded slider 20, when the screws 21 are away from the threaded slider 20, the user can directly pull out the storage rack 22, put an ice bag into the storage cavity 23, push the storage rack 22 into the main box 11, and then tighten the screws 21, so that the food can continue to keep warm when it is delivered to the destination.

[0034] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
