[0025] This specification provides one or more embodiments of a thermal insulation structure for a low-temperature logistics warehouse, such as... Figure 1 , Figure 2 and Figure 5 As shown, it includes a heat insulation box 1, which is a cavity structure with openings at both ends. The heat insulation box 1 is provided with a door 2 at each end. The heat insulation box 1 is provided with two sets of support mechanisms. Each set of support mechanisms includes several vertically arranged load plates 3. The heat insulation box 1 is equipped with support members for supporting the load plates 3.

[0026] A lead screw 6 is provided between the two sets of support mechanisms. The bottom end of the lead screw 6 is rotatably connected to the heat insulation box 1. A rotating shell 7 is rotatably sleeved on the outside of the lead screw 6. A lifting seat 8 located above the rotating shell 7 is sleeved on the outside of the lead screw 6. The rotating shell 7 and the lifting seat 8 are connected by a threaded connection. At least one first guide bar 9 is fixedly connected to the top of the rotating shell 7, and the first guide bar 9 passes through the lifting seat 8.

[0027] The lifting seat 8 is equipped with a translation component for pushing the load plate 3 to move horizontally. The heat insulation box 1 is equipped with a drive mechanism that drives the lead screw 6 and the first guide bar 9 to rotate. When the operator opens the box door 2, the drive mechanism drives the lead screw 6 to rotate, so that the lead screw 6 drives the lifting seat 8 to slide vertically relative to the first guide bar 9, changing the height of the lifting seat 8 and the translation component. When the lifting seat 8 and the translation component move to the preset height, the drive mechanism drives the lead screw 6 and the first guide bar 9 to rotate synchronously. The first guide bar 9 drives the lifting seat 8 and the translation component to rotate below the corresponding load plate 3. The drive mechanism drives the lead screw 6 to rotate again, and the lead screw 6 drives the lifting seat 8 and the translation component to move upward, so that the translation component supports the corresponding load plate 3. The support is then used to move the carrying plate 3 out of the heat insulation box 1 via the translation component. The staff removes the carrying plate 3 from the translation component and places the next carrying plate 3 to be placed in the heat insulation box 1 on the translation component. Similarly, by reversing the above steps, the carrying plate 3 can be automatically stored in the heat insulation box 1. The staff places the carrying plate 3 in a preset position outside the heat insulation box 1, and the carrying plate 3 will be automatically stored in the heat insulation box 1. The heat insulation box 1 provides insulation, eliminating the need for manual placement and installation of the carrying plate 3 inside the heat insulation box 1, thus improving convenience. This also avoids collisions between the carrying plate 3 and the inside of the heat insulation box 1, reducing the possibility of items falling from the carrying plate 3 and causing injury to personnel, thereby improving safety.

[0028] In embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 5 As shown, the translation component includes a rectangular frame 10 fixedly installed on the lifting base 8. A support base 12 is provided above the rectangular frame 10. A first electric push rod 11 is fixedly installed on the rectangular frame 10. The telescopic end of the first electric push rod 11 and the bottom of the support base 12 are fixedly connected through a support part 13. Several slots 15 are provided on the top of the support base 12. Several clips 14 that are adapted to the slots 15 are fixedly connected to the bottom of the carrying plate 3. Fixing frames 16 are fixedly connected to both sides of the support base 12, and the fixing frames 16 are located at the end of the support base 12 away from the support part 13. First guide grooves are provided on both sides of the rectangular frame 10. 17. A guide block 18 is slidably provided in the first guide groove 17, and the guide block 18 is fixedly connected to the fixing frame 16. The support includes a support plate 25 and a side plate 26 respectively provided on both sides of the carrying plate 3. The support plate 25 and the side plate 26 are fixedly connected to the inner wall of the heat insulation box 1. The top of the support plate 25 is in contact with the bottom of the carrying plate 3. A second guide groove 27 is provided on the side plate 26. A second guide strip 28 is slidably provided in the second guide groove 27. The second guide strip 28 is fixedly connected to the carrying plate 3. An iron plate 29 is fixedly connected to the second guide strip 28. An iron block 30 adapted to the iron plate 29 is fixedly connected to the side plate 26.

[0029] When the lifting seat 8 and the translating component rotate to a position below the corresponding carrying plate 3, the drive mechanism drives the lead screw 6 to rotate again. The lead screw 6 drives the lifting seat 8 and the translating component to move upward, so that the locking strip 14 is inserted into the corresponding locking slot 15. The first electric push rod 11 drives the support part 13 and the support base 12 to translate. The support base 12 can then drive the corresponding carrying plate 3 to translate via the locking strip 14. The support base 12 drives the guide block 18 to slide in the first guide groove 17 via the fixing frame 16. The design of the fixing frame 16, the first guide groove 17, and the guide block 18 increases the stability of the support base 12 and the carrying plate 3 during translation. When the carrying plate 3 moves, it slides relative to the support plate 25, and the support plate 25 no longer supports the carrying plate 3. The carrying plate 3 drives the second guide bar 28 to slide from the second guide groove 27, and the iron plate 29 is no longer magnetically attracted to the iron block 30. When the support base 12 moves in the opposite direction so that the carrying plate 3 drives the second guide bar 28 to slide into the second guide groove 27 again, the iron plate 29 is magnetically attracted to the iron block 30 again, and the support plate 25 supports the carrying plate 3. Through the design of the iron plate 29 and the iron block 30, when the support base 12 moves down and the locking bar 14 disengages from the locking groove 15, the possibility of the carrying plate 3 swaying relative to the heat insulation box 1 is reduced, and the stability is increased.

[0030] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the top of the heat insulation box 1 is provided with an air inlet pipe 4, and the bottom of the heat insulation box 1 is provided with an air outlet pipe 5. Both the air inlet pipe 4 and the air outlet pipe 5 are provided with valves. The driving mechanism includes a protective shell 19 fixedly installed on the top of the heat insulation box 1. A servo motor 20 is fixedly connected to the top of the protective shell 19. The top of the lead screw 6 passes through the protective shell 19. The output end of the servo motor 20 passes through the protective shell 19. The output end of the servo motor 20 and the top of the lead screw 6 are fixedly connected. A support column 24 is rotatably connected to the heat insulation box 1. The first guide bar 9 and the lead screw 6 both pass through the support column 24. The protective shell 19 is equipped with a swing unit for driving the first guide bar 9 to rotate. The swing unit includes a gear 21 set in the protective shell 19. The top of the first guide bar 9 and the gear 21 are fixedly connected. The protective shell 19 is fixedly installed with a second electric push rod 22. The output end of the second electric push rod 22 is fixedly connected to a toothed plate 23 that meshes with the gear 21.

[0031] Cold air is injected into the heat insulation box 1 through the air inlet pipe 4 and discharged through the air outlet pipe 5. By circulating cold air into the heat insulation box 1, the temperature inside the heat insulation box 1 can reach the preset value. The lead screw 6 is driven to rotate by the servo motor 20. When the first guide bar 9 is stationary, the lead screw 6 can drive the lifting seat 8 to slide vertically relative to the first guide bar 9. When it is necessary to drive the lifting seat 8 to rotate so that the translation component can rotate, the toothed plate 23 is driven to move by the second electric push rod 22. The toothed plate 23 drives the first guide bar 9 to rotate through the gear 21, and the servo motor 20 drives the lead screw 6 to rotate synchronously. This allows the first guide bar 9, the lifting seat 8 and the lead screw 6 to rotate synchronously, changing the position of the translation component. The first guide bar 9 also drives the support column 24 to rotate relative to the heat insulation box 1. The design of the support column 24 reduces the possibility of the first guide bar 9 tilting or swaying relative to the heat insulation box 1.
