[0002] In recent years, with the booming development of e-commerce and the improvement of consumers' awareness of food safety, the demand for cold chain logistics has increased. As a common means of transportation in cold chain logistics, turnover boxes play an important role in the short-distance distribution of sensitive items such as fresh food and medicines due to their moderate size, easy handling and stacking. These turnover boxes not only need to have good thermal insulation performance, but also facilitate real-time monitoring and management of information to ensure the quality and safety of goods throughout the transportation process.

[0003] Although the existing cold chain logistics turnover boxes have certain insulation capabilities and basic temperature monitoring functions, there are still deficiencies in the structural design. Specifically, in order to achieve better insulation effects, most medium-sized turnover boxes use thicker insulation materials, which not only increases the weight of the box itself, but also reduces the available loading space inside, reducing transportation efficiency. In addition, due to unreasonable internal structural design, the air circulation inside the box is poor, which can easily lead to local temperature differences, affecting the quality and shelf life of the goods. These problems limit the application scope and efficiency of medium-sized turnover boxes in cold chain logistics. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-5The present invention provides a technical solution: a logistics cold chain box for the Internet of Things, comprising a cold chain box body 1, the top cover of the cold chain box body 1 is closed with a box cover 2, the cold chain box body 1 adopts a double-layer composite structure consisting of an outer hard shell layer 101 and an inner light insulation material layer 102, a plurality of evenly distributed support columns 103 are arranged between the hard shell layer 101 and the light insulation material layer 102, and a bottom partition 3 is arranged at the bottom end of the interior of the cold chain box body 1, the bottom partition 3 divides the space at the upper and lower ends of the interior of the cold chain box body 1 into a storage cavity and an air circulation cavity, and a main partition 5 is arranged in the middle of the top of the bottom partition 3, and adjustment seats 6 are arranged on both sides of the main partition 5, and auxiliary partitions 7 that can be adjusted in multiple positions are stored and released inside the adjustment seat 6. When the cold chain box body 1 of this structure is in use The hard shell layer 101 provides a solid external protection to prevent external impact from causing damage to the items in the box. The inner lightweight insulation material layer 102 effectively blocks the transfer of external heat and maintains a low temperature environment in the box. The combination of the two not only reduces the weight of the box, but also ensures excellent thermal insulation performance. The support columns 103 are evenly distributed between the two layers of material, which enhances the stability of the box structure and also plays a supporting role, avoiding the loss of cold caused by direct contact between the inner and outer materials. The design of the bottom partition 3 divides the internal space of the cold chain box body 1 into two parts, the upper part is a storage cavity, and the lower part is an air circulation cavity, which is conducive to promoting the natural circulation of air in the box, ensuring the uniform distribution of temperature in the box, and avoiding the negative impact caused by local temperature differences. The combined use of the partition 5, the adjustment seat 6 and the auxiliary partition 7 can flexibly adjust the internal space layout according to actual needs to adapt to the storage requirements of goods of different sizes and types, improve the space utilization rate, and ensure the safety and stability of the goods. It solves the problems of unreasonable internal space utilization and poor air circulation in the logistics cold chain box in the prior art. The air circulation cavity at the bottom end of the cold chain box main body 1 is evenly provided with a plurality of air holes 4. The air holes 4 are located on the side wall at the bottom end of the rear side of the cold chain box main body 1, and the outer hinges are covered, and the air holes 4 are provided with filter mesh sheets inside. The air holes 4 of this structure ensure that the air inside the cold chain box main body 1 can circulate smoothly, avoiding the local temperature unevenness caused by air stagnation, and the filter mesh sheet effectively blocks the outside To prevent dust and impurities from entering the box, a horizontally distributed push plate 61 is provided inside the adjustment seat 6, and a push shaft 62 is provided in the middle of the top of the push plate 61, and a positioning sleeve 63 is provided on the inner wall in the middle of the top of the adjustment seat 6 to form a sliding connection with the push shaft 62, and a locking screw is connected to the positioning sleeve 63 through a threaded structure. With this structure, the operator can adjust the position of the push shaft 62 in the positioning sleeve 63 by rotating the locking screw, thereby driving the push plate 61 to move vertically along the inside of the adjustment seat 6. The movement of the push plate 61 will push or pull the auxiliary partition 7, so as to realize the precise adjustment of the auxiliary partition 7 at different horizontal positions inside the cold chain box body 1. This not only allows the internal space of the cold chain box body 1 to be flexibly adjusted according to the actual size and quantity of the goods, but also improves the space utilization rate.The auxiliary partition 7 is firmly positioned to ensure the safety and stability of the goods. Guide blocks 64 are welded and fixed at both ends of the push strip plate 61, and the inner walls on both sides of the adjustment seat 6 are provided with vertical guide grooves that match the guide block 64 structure. The push strip plate 61 of this structure can drive the guide block 64 to slide up and down along the vertical guide grooves on the inner walls on both sides of the adjustment seat 6, ensuring the stability and linearity of the push strip plate 61 during movement, and avoiding the deviation of the push strip plate 61 during the adjustment process, which makes the adjustment of the auxiliary partition plate 7 smoother and more precise. The auxiliary partition plate 7 is a telescopic structure composed of an inner plate 71 and an outer plate 72. The outer end of the inner plate 71 is provided with a telescopic groove that matches the inner end structure of the outer plate 72, and an elastic support pad 73 is provided in the telescopic groove inside the outer end of the inner plate 71. When the lock body 7 is in the unlocking state, the lock body 71 is in the unlocking state, and the lock body 72 is in the unlocking state, so that the lock body 72 is locked. To maintain the stability of the auxiliary partition 7 when it is adjusted to a horizontal state, both sides of the inner end of the inner plate 71 are movably connected to the push strip plate 61 by hinges, and the outer end of the outer plate 72 is bonded and fixed with a rubber strip. With this structure, the auxiliary partition 7 can be adjusted in angle under the drive of the push strip plate 61, which increases the flexibility and adaptability of the auxiliary partition 7, and the rubber strip bonded and fixed to the outer end of the outer plate 72 can fit tightly against the inner wall of the cold chain box body 1 after the auxiliary partition 7 is stretched into place, thereby playing a sealing and buffering role. The main partition 5 is vertically distributed in the middle of the top of the bottom partition 3, and the connection between the bottom end of the main partition 5 and the middle of the top of the bottom partition 3 is screwed and fixed. With this structure, the main partition 5 is fixedly connected to the bottom partition 3 by screwing, ensuring that the main partition 5 is in the cold chain box body 1 The vertical stability of the bottom, a number of through holes are evenly arranged on the bottom partition 3, and the diameter of the through holes on the bottom partition 3 is 5-10mm, and the spacing is 20-30mm. The through holes on the bottom partition 3 of this structure ensure that the air can flow smoothly between the upper and lower spaces inside the cold chain box body 1, avoiding the local temperature unevenness caused by air stagnation. The support column 103 is a hollow cylindrical structure, and the support column 103 is filled with a phase change material made of a paraffin-based composite material. The support column 103 of this structure not only provides the necessary support and enhances the structural stability of the cold chain box body 1, but also realizes adaptability to temperature changes through the paraffin-based composite phase change material filled inside, that is, when the ambient temperature rises, the phase change material changes from solid to liquid, absorbing excess heat,When the ambient temperature drops, the phase change material changes from liquid to solid, releasing the stored heat. This phase change process can effectively balance and regulate the temperature inside the cold chain box and reduce temperature fluctuations. Working principle: When using the logistics cold chain box for the Internet of Things, first adjust the position of the auxiliary partition 7 by adjusting the push plate 61 inside the seat 6 according to the size and quantity of the goods. During specific operation, the operator can adjust the position of the push shaft 62 in the positioning sleeve 63 by rotating the locking screw, thereby driving the push plate 61 to slide up and down along the vertical guide groove inside the adjustment seat 6. The movement of the push plate 61 will push or pull the auxiliary partition 7, so that it can be accurately adjusted to different horizontal positions inside the cold chain box body 1, and the auxiliary partition 7 can be telescopically matched through the inner plate 71 and the outer plate 72. When the auxiliary partition 7 is pushed in or pulled out, the outer plate 72 slides along the telescopic groove under the action of external force, and the elastic support pad 73 provides a certain elastic supporting force, so that the outer plate 72 can be horizontally supported and extended after being extended into place. Press against the inner wall of the cold chain box body 1 to ensure the stability of the auxiliary partition 7. After the adjustment is completed, pass the two locking bolts 74 through the grooves on the inner plate 71 and screw them into the threaded holes on the outside of the push plate 61 to firmly fix the inner plate 71 on the push plate 61 to further maintain the stability of the auxiliary partition 7 adjusted to a horizontal state. At this time, close the box cover 2 on the top of the cold chain box body 1 to ensure that the box cover 2 fits tightly against the cold chain box body 1 to form a closed heat-insulating environment. When the cold chain box body 1 is in use, the cover on the outside of the air vent 4 can be opened to allow outside air to enter the air circulation cavity inside the cold chain box body 1 through the air vent 4, and then be evenly distributed to various areas inside the cold chain box body 1 through the through holes on the bottom partition 3, thereby promoting the natural circulation of air in the box, thereby completing a series of tasks.
