The movable sleeves are sleeved on the outer side of the sliding rod, and the movable sleeves are slidingly connected to the sliding rod. The internal threads of the movable sleeves are connected with tightening bolts, and the tightening bolts are in contact with the sliding rod.

[0027] By adopting the above technical solution, the placement plate is pulled, and the placement plate drives the movable sleeve to slide in the vertical groove. After adjustment, the tightening bolt is tightened to facilitate the upward and downward adjustment of the position of the placement plate, so as to better adapt to the size of the goods for placement and use.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. An absorption component is provided. The goods are placed inside the thermal insulation box. The thermal insulation box stores different goods separately. The activated carbon plate absorbs the odor emitted by the goods. When the goods are stored in the thermal insulation box, the operator starts the servo motor through an external switch. The servo motor drives the lead screw to rotate. The three guide rods limit the moving bars on both sides. The lead screw drives the moving bar to move up and down. When the moving bar rises, it drives the connecting bar and the tooth block to move. The tooth block drives the gear to rotate, and the length of the tooth block is just enough to drive the gear to rotate half a circle. The gear drives the mounting frame to flip, so that the unused activated carbon plate on the back of the mounting frame is turned out for use, thereby improving the effect of absorbing odors. The mounting frame is made of iron material, so that when the gear is not driven by the tooth block, the mounting frame and the magnetic strip are adsorbed and positioned, reducing the mounting frame. In the case of autonomous tilting, the movement of the moving bar will drive the moving block and the erasing bar to move, and the erasing bar moves up and down to scrape the two side walls of the insulation box. When the moving block contacts the wider middle position of the blocking piece, the two moving blocks are squeezed and expanded by the blocking piece, and the two moving blocks stretch the spring. When the moving block is separated from the wider middle position of the blocking piece, the elastic force of the spring drives the moving block to reset and fit the vertical bar. The inclined surfaces on both sides of the blocking piece assist the moving block to move back and forth smoothly horizontally, realizing the longitudinal reciprocating scraping of the erasing bar. Combined with the up and down scraping, the cleaning effect of the two side walls of the insulation box is improved, the adhesion of residues and the residual odor are reduced, and the problem of inconvenience in timely absorption and treatment of the odor generated by the goods is solved, which causes the odor to cross between adjacent goods, thereby reducing the quality of the goods.

[0030] 2. An adjustment component is provided. When placing goods, the operator opens the second door and adjusts the distance between the placement plates according to the height of the goods. By loosening the fastening bolts on both sides of the placement plates, the fastening bolts on the slide rod are released, so that the movable sleeve can slide on the slide rod. Then the placement plate is pulled, and the placement plate drives the movable sleeve to slide in the vertical slot. After adjustment, the fastening bolts are tightened again to facilitate the up and down adjustment of the position of the placement plate, thereby better adapting to the size of the goods for placement and improving the flexibility of use.

[0031] 3. When packing the insulation box, open the box door and the operator uses a cart to push the insulation box into the interior of the transport box so that the insulation box is located on one side of the center bar and the limit bar is located inside the bottom groove. At this time, the guide wheel is located between two adjacent limit bars. The guide wheel and the center bar guide the insulation box to facilitate stable sliding placement. The center bar limits the insulation boxes on both sides to reduce the impact of subsequent transportation bumps on the insulation box. The compression refrigerator is used for cooling to keep the insulation box inside the transport box at a low temperature. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating groove 87 is provided on the back of the inner wall of the insulation box body 5. Gears 88 are symmetrically connected to the two sides of the rotating groove 87. The gears 88 are meshed with the tooth blocks 86. The same mounting frame 89 is fixedly connected between the two gears 88, and the activated carbon plate 15 is fixedly installed symmetrically on the front and back inside the mounting frame 89.

[0052] The screw rod 82 and the three guide rods 83 are evenly distributed around the interior of the insulation box 5. The tooth block 86 is vertically arranged, and the length of the tooth block 86 is equal to the semi-circumference of the outer ring of the gear 88. The rotating groove 87 is evenly opened from top to bottom, and there are no less than two rotating grooves 87.

[0053] The gear 88 is rotatably connected to the rotating groove 87, and the gear 88 protrudes from the outside of the rotating groove 87, so that the tooth block 86 can smoothly engage with the gear 88 when moving up and down. The inner side of the rotating groove 87 is symmetrically fixed with a magnetic strip 810, and the mounting frame 89 is made of iron material.

[0054] A side groove 811 is provided on one side of the moving bar 84, and an inner rod 812 is fixedly connected to the inside of the side groove 811. A moving block 813 is slidably connected to the outer side of the inner rod 812. The side of the moving block 813 away from the moving bar 84 is fixedly connected to the erasing bar 814, and a spring 815 is sleeved on the middle part of the outer side of the moving block 813. A yield groove 816 is provided on the other side of the moving bar 84, and blocking pieces 817 are evenly fixedly connected to the upper and lower sides of the side plate 7 close to the moving bar 84, and a vertical bar 818 is fixedly connected between the upper and lower blocking pieces 817.

[0055] The moving block 813 fits against the inner wall of the side groove 811 . The two moving blocks 813 are located on both sides of the spring 815 . The spring 815 is slidably connected to the inner rod 812 . Both ends of the spring 815 are fixedly connected to the two moving blocks 813 .

[0056] The side of the moving block 813 away from the erasing bar 814 extends into the clearance groove 816, and the two moving blocks 813 are attached to both sides of the vertical bar 818, and the width of the vertical bar 818 is the same as the width of the top and bottom surfaces of the blocking piece 817. The longitudinal section of the blocking piece 817 is a regular octagon.

[0057] Example 1: Figure 1 and Figures 5 - 12 As shown, the goods are placed inside the insulation box 5, and the insulation box 5 stores different goods separately. The activated carbon plate 15 absorbs the odor emitted by the goods. When the insulation box 5 stores the goods in a closed manner, the operator starts the servo motor 81 through an external switch. The servo motor 81 drives the screw rod 82 to rotate, and the three guide rods 83 limit the moving bars 84 on both sides. The screw rod 82 drives the moving bar 84 to move up and down. When the moving bar 84 rises, it drives the connecting bar 85 and the tooth block 86 to move, and the tooth block 86 drives the gear 88 to rotate.

[0058] The length of the tooth block 86 is just enough to drive the gear 88 to rotate half a circle. The gear 88 drives the mounting frame 89 to flip over, so that the unused activated carbon plate 15 on the back of the mounting frame 89 is turned out for use, thereby improving the effect of absorbing odors. The mounting frame 89 is made of iron material, so that when the gear 88 is not driven by the tooth block 86, the mounting frame 89 and the magnetic strip 810 are adsorbed and positioned, reducing the situation of the mounting frame 89 tilting autonomously.

[0059] At the same time, the movement of the moving bar 84 will drive the moving block 813 and the erasing bar 814 to move, and the erasing bar 814 will move up and down to scrape the two side walls of the insulation box 5. When the moving block 813 contacts the wider middle position of the blocking piece 817, the two moving blocks 813 are squeezed and expanded by the blocking piece 817, and the two moving blocks 813 stretch the spring 815. When the moving block 813 is separated from the wider middle position of the blocking piece 817, the elastic force of the spring 815 drives the moving block 813 to reset and fit the vertical bar 818. The inclined surfaces on both sides of the blocking piece 817 assist the moving block 813 to move back and forth smoothly horizontally, realizing the longitudinal reciprocating scraping of the erasing bar 814, and coordinating with the up and down scraping, the cleaning effect of the two side walls of the insulation box 5 is improved, the adhesion of residues and the residual odor are reduced, and the problem of inconvenience in timely absorption and treatment of the odor generated by the goods is solved, which causes the odor to cross between adjacent goods, thereby reducing the quality of the goods.

[0060] An adjustment assembly 9 is provided on the inner side of the two side panels 7. The adjustment assembly 9 includes placement plates 91 that are evenly arranged laterally. The placement plates 91 are located between the two side panels 7. There are no less than two placement plates 91. A vertical groove 92 is vertically opened on one side of the side panel 7 close to the placement plate 91. A sliding rod 93 is fixedly connected to the inside of the vertical groove 92.

[0061] The placement plate 91 is fitted with the side plate 7, and the two sides of the placement plate 91 are symmetrically fixed with movable sleeves 94, which are sleeved on the outside of the slide rod 93. The movable sleeve 94 is slidingly connected to the slide rod 93, and the internal thread of the movable sleeve 94 is connected with a tightening bolt 95, which abuts against the slide rod 93.

[0062] Example 2: Figures 13 - 14 As shown, when placing goods, the operator opens the box door 26, adjusts the distance between the placement plates 91 according to the height of the goods, and releases the tightening bolts 95 on both sides of the placement plates 91 to release the tightening bolts 95 on the slide rod 93, so that the movable sleeve 94 can slide on the slide rod 93, and then pull the placement plate 91, and the placement plate 91 drives the movable sleeve 94 to slide in the vertical groove 92. After adjustment, the tightening bolts 95 are tightened again to facilitate the up and down adjustment of the position of the placement plate 91, so as to better adapt to the size of the goods for placement and use, thereby improving the flexibility of use.

[0063] On one side inside the transport box body 1, a partition 3 is fixedly connected, and on one side of the partition 3, a compression refrigeration machine 4 is fixedly installed. The model of the compression refrigeration machine 4 is Carrier RV580.

[0064] An installation box 10 is fixedly installed on the inner top surface of the transport box body 1. The installation box 10 is located on the side of the partition 3 away from the compression refrigeration machine 4. Through holes are evenly formed inside the installation box 10. At the lower part on the other side of the partition 3, a central strip 11 is fixedly connected, and the central strip 11 is fixedly connected to the inner bottom surface of the transport box body 1.

[0065] On the inner bottom surface of the transport box body 1, limiting strips 12 are symmetrically and fixedly connected. A bottom groove 13 is horizontally formed at the bottom of the heat preservation box body 5. A guide wheel 14 is longitudinally rotatably connected inside the bottom groove 13, and the guide wheel 14 is slidably connected to the limiting strip 12.

[0066] Embodiment 3: As Figures 2 - 5 shown, when the heat preservation box body 5 is loaded into the box, the box door 2 is opened. An operator uses a trolley to push the heat preservation box body 5 into the interior of the transport box body 1, so that the heat preservation box body 5 is located on one side of the central strip 11, and the limiting strip 12 is located inside the bottom groove 13. At this time, the guide wheel 14 is located between two adjacent limiting strips 12. Through the guiding of the guide wheel 14 and the central strip 11, the stable sliding placement of the heat preservation box body 5 is facilitated. The central strip 11 limits the heat preservation box bodies 5 on both sides, reducing the influence of subsequent transportation bumps on the heat preservation box body 5. The compression refrigeration machine 4 is used for refrigeration. The cold air of the compression refrigeration machine 4 blows onto the heat preservation box body 5 through the through holes on the installation box 10, maintaining the low-temperature storage of the heat preservation box body 5 inside the transport box body 1.

[0067] Working principle: When using this device, first, as Figures 1 - 14As shown, the operator opens the second box door 6. By loosening the fastening bolts 95 on both sides of the placement plate 91 and pulling the placement plate 91, it is convenient to adjust the position of the placement plate 91 up and down, so as to better adapt to the size of the goods for placement and use. The heat preservation box body 5 stores different goods separately, and the activated carbon plate 15 absorbs the peculiar smell emitted by the goods. The operator starts the servo motor 81 to work through an external switch, and the gear 88 drives the mounting frame 89 to turn over, so that the unused activated carbon plate 15 on the back of the mounting frame 89 is turned out for use, thereby improving the effect of absorbing peculiar smell. At the same time, the movement of the moving strip 84 will drive the moving block 813 and the wiping strip 814 to move. The wiping strip 814 scrapes the two side walls of the heat preservation box body 5 up and down. The moving block 813 is squeezed and unfolded by the blocking piece 817. When the moving block 813 separates from the wider middle position of the blocking piece 817, the elastic force of the spring 815 drives the moving block 813 to reset and fit the vertical strip 818. The inclined surfaces on both sides of the blocking piece 817 assist the moving block 813 to move smoothly back and forth horizontally, realizing the longitudinal reciprocating scraping of the wiping strip 814 and improving the cleaning effect on the two side walls of the heat preservation box body 5. When loading the heat preservation box body 5, open the first box door 2. The operator uses a trolley to push the heat preservation box body 5 into the inside of the transportation box body 1. Through the guidance of the guide wheels 14 and the center strip 11, it is convenient to stably slide and place the heat preservation box body 5. The compression refrigerator 4 is used for refrigeration to keep the heat preservation box body 5 in the transportation box body 1 stored at a low temperature.
