During the use, when preventing scraping roller 401 contact transport box inner wall and taking place to remove, roll body 4012 on the pivot 4011 rotates and reduces the friction, and rubber sleeve 4013 avoids causing wearing and tearing after roll body 4012 rubs with the transport box inner wall.

In fig. 5, 6 and 7: the fastening assembly 8 comprises fixing seats 801 fixed on two sides of the bottom end face of the top plate 3, threaded through holes 805 are formed in the fixing seats 801, positioning bolts 802 are connected with the threaded through holes 805 in a threaded mode, positioning plates 803 are fixedly connected on two sides of the bottom end face of the cover plate 6, positioning screw holes 804 are formed in the side faces of the positioning plates 803, the distance between the two positioning plates 803 is equal to the length of the box body 1, and one ends of the positioning bolts 802 extend and are screwed into the positioning screw holes 804. In use, after the cover plate 6 is covered on the notch 5, the positioning plate 803 is inserted into the gap between the notch 5 and the box body 1, and then the positioning bolt 802 is screwed so that one end of the positioning bolt 802 passes through the threaded through hole 805 and is screwed into the positioning screw hole 804 of the positioning plate 803, thereby fixing the cover plate 6 in the notch 5.

In fig. 7 and 8: the placing groove 11 has been seted up to the inside of box 1, and 11 top openings of placing groove, and the inside wall swing joint of placing groove 11 has cold-storage baffle 12. The cold storage partition 12 can create a cold environment in the placement groove 11. The cold storage partition plate 12 comprises a plate body 1201, the two ends of the plate body 1201 are inserted into slots in the inner side wall of the placing groove 11, a cold storage groove 1202 is formed in the plate body 1201, an upper plate 1203 is arranged at the upper end of the plate body 1201, and a rubber plug 1204 is fixedly connected to the bottom end face of the upper plate 1203. When the cold storage device is used, the cold storage agent is placed into the cold storage tank 1202, the rubber plug 1204 of the upper plate 1203 is clamped into the cold storage tank 1202, and then the plate body 1201 and the upper plate 1203 are tightly connected to avoid the leakage of the cold storage agent. Food grade coolant is placed inside the coolant reservoir 1202. The safety of the food-grade coolant is higher, and the coolant is prevented from leaking to pollute articles in the placing groove 11.

The working principle is as follows: when the cold-chain logistics box is used, firstly, the cover plate 6 is opened through the buckle groove 7, and the placing groove 11 of the box body 1 is exposed. Then, take out cold-storage baffle 12, open upper plate 1203, put into cold-storage tank 1202 with the good food level coolant of freezing, it is fixed to go into cold-storage tank 1202 with the rubber buffer 1204 of plate body 1201 card again, insert cold-storage baffle 12 again in standing groove 11 afterwards, put into standing groove 11 with the article that need the refrigerated transport again. Finally, the cover plate 6 is closed, the positioning plate 803 is inserted into the gap between the notch 5 and the box body 1, and the cover plate 6 is fixed in the notch 5 through the fastening assembly 8. The method specifically comprises the following steps: the positioning bolt 802 is screwed so that one end of the positioning bolt 802 passes through the threaded through hole 805 and is screwed into the positioning screw hole 804 of the positioning plate 803, thereby fixing the cover plate 6 in the notch 5, and facilitating fastening or opening of the cover plate 6.

6 backs of covering, the staff will prevent scraping subassembly 4 and install on the thing flow box, specifically be: the first limiting block 404 and the second limiting block 405 are respectively clamped into the first limiting groove 9 and the second limiting groove 10, the fastening knob 406 is screwed on the corresponding threaded column 407, the threaded column 407 continuously penetrates into the threaded groove 4061 along with the screwing of the fastening knob 406 until the fastening knob 406 abuts against the limiting blocks, and the fixing mode is simple and convenient and is convenient to use. After fixing, owing to adopted fastening knob 406, during the use, after will preventing scraping the subassembly 4 and installing, staff's accessible fastening knob 406 puts a plurality of cold chain logistics boxes stack together. The method specifically comprises the following steps: one cold-chain logistics box is put well, and then the clamping groove 4062 of the fastening knob 406 at the bottom end of the other cold-chain logistics box is positioned and clamped at the upper part of the fastening knob 406 at the top end of the previous cold-chain logistics box. By analogy, a plurality of cold chain logistics boxes are conveniently stacked together, and later-stage transportation and use are facilitated.

And through the bottom plate 2 and the top plate 3 that set up, can carry out certain protection to the box 1 of depositing article, avoid outside object direct interference box 1, the staff still can be through the quick laborsaving box 1 of moving of top plate 3, the staff of being convenient for uses. In the transportation, if the thing flow box rocks to the transport case inner wall, at first with the contact of transport case inner wall prevent scraping subassembly 4 prevent scraping roller 401, it is impaired to prevent scraping roller 401 to avoid the 1 direct contact transport case inner wall of box of this thing flow box, and the cooperation of limiting plate and stopper is used and is convenient for prevent scraping roller 401's quick installation and dismantlement, effectively solved among the prior art thing flow box in the transportation its surface easy by the impaired technical problem of scratch, and then realized that thing flow box in the transportation its surface is difficult by the impaired technological effect of scratch. In addition, when the scratch prevention roller 401 contacts the inner wall of the transport box and moves, the roller body 4012 on the rotating shaft 4011 rotates to reduce friction, and the rubber sleeve 4013 prevents the roller body 4012 from being abraded after being rubbed with the inner wall of the transport box.

Therefore, the present invention is not limited to the above embodiments, and any person skilled in the art can substitute or change the technical solutions and concepts of the present invention within the technical scope of the present disclosure.
