[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6This utility model provides a technical solution: a frozen food transport packaging box, including a box body 1. A guide groove 2 is provided on the rear inner wall of the box body 1. A threaded rod 11 is rotatably connected inside the guide groove 2. An installation block 3 is slidably connected inside the guide groove 2. The installation block 3 is movably sleeved on the outside of the threaded rod 11. A placement plate 4 is provided on the outside of the installation block 3. A first cavity 5 is provided inside the installation block 3. A threaded connecting sleeve 6 is rotatably connected inside the first cavity 5. The threaded connecting sleeve 6 is threaded on the outside of the threaded rod 11. A first worm gear 7 is fixedly sleeved on the outside of the threaded connecting sleeve 6. A first worm 8 is meshed on the outside of the first worm gear 7. The first worm 8 is rotatably connected to the inner wall of the first cavity 5 through a shaft. A second cavity 12 is provided inside the box body 1. The upper end of the threaded rod 11 rotatably penetrates into the inside of the second cavity 12. A drive assembly is provided on the outside of the threaded rod 11.

[0025] The upper surface of the mounting block 3 is rotatably connected to a first operating lever 9. The lower end of the first operating lever 9 rotatably penetrates into the interior of the first cavity 5. Both the lower end of the first operating lever 9 and the outer side of the shaft of the first worm 8 are fixedly fitted with bevel gears 10. The two bevel gears 10 are meshed and connected. By rotating the first operating lever 9 and the two bevel gears 10, the rotation of the first worm 8 can be driven. The rotation of the first worm 8 can drive the rotation of the first worm wheel 7. The rotation of the first worm wheel 7 can drive the rotation of the threaded connecting sleeve 6. At this time, since the threaded rod 11 of the drive assembly does not rotate, the rotation of the threaded connecting sleeve 6 can drive the mounting block 3 and the placement plate 4 to move, thereby realizing the adjustment of the height of the placement plate 4.

[0026] The drive assembly includes a second worm gear 13, which is fixedly sleeved on the outside of the threaded rod 11. The second worm gear 13 is located inside the second cavity 12, and a second worm 14 is meshed with the outside of the second worm gear 13. The second worm 14 is rotatably connected to the inside of the second cavity 12 via a shaft. The self-locking property between the second worm 14 and the second worm gear 13 ensures the stability of the second worm gear 13. Therefore, when the threaded connecting sleeve 6 rotates, it will not drive the threaded rod 11 to rotate. Subsequently, by rotating the second worm 14, the rotation of the second worm gear 13 can drive the rotation of the threaded rod 11, thereby driving the rotation of the threaded rod 11. At this time, due to the self-locking property between the first worm 8 and the first worm gear 7, the threaded connecting sleeve 6 will not rotate. This allows the two mounting blocks 3 to move simultaneously outside the threaded rod 11, thereby enabling the height of the two placement plates 4 to be adjusted simultaneously.

[0027] A second operating lever 15 is rotatably connected to the rear surface of the housing 1. The second operating lever 15 rotatably penetrates into the interior of the second cavity 12 and is fixedly connected to the second worm gear 14. Rotating the second operating lever 15 can drive the rotation of the second worm gear 14.

[0028] Two water storage tanks 16 are provided on the upper surface of the placement plate 4. The inner walls of the two water storage tanks 16 are provided with through grooves 17. Water passages 18 are provided on both sides of the inner walls of the box body 1. The water storage tanks 16 are connected to the through grooves 17 and the water passages 18.

[0029] The bottom plate of the box 1 has a water storage chamber 19 inside, which is connected to the water passage 18. The front surface of the box 1 has a water outlet 20. The water accumulated on the surface of the placement plate 4 can be guided to the inside of the water storage tank 16 by the inclined surface of the placement plate 4. Then, the water is discharged into the inside of the water passage 18 through the through groove 17 and enters the inside of the water storage chamber 19 for collection, so that the water can be discharged later.

[0030] In the above embodiment, the bottom wall of the box 1 and the upper surface of the placement plate 4 are both set with a slight slope.

[0031] The placement plate 4 has a sliding groove 21 inside, and a trapezoidal block 22 is slidably connected inside the sliding groove 21. The surface of the mounting block 3 has a slot that communicates with the inside and is adapted to the trapezoidal block 22. A return spring 23 is fixedly connected between the trapezoidal block 22 and the inner wall of the sliding groove 21. When the placement plate 4 is disassembled or installed, it is only necessary to make the inclined surface of the trapezoidal block 22 contact the mounting block 3. At this time, the trapezoidal block 22 can slide inside the sliding groove 21 by means of the inclined surface. The return spring 23 will generate elastic deformation so that the trapezoidal block 22 can be inserted into the inside of the mounting block 3 after the slot on the surface of the mounting block 3 is aligned.

[0032] The trapezoidal block 22 has a slot 24 on its surface. The mounting block 3 has a threaded connection to a plug screw 25. The plug screw 25 and the slot 24 are compatible. When the trapezoidal block 22 is inserted into the mounting block 3, the plug screw 25 is inserted into the slot 24 to achieve secondary fixation, thereby effectively ensuring the stability of the placement plate 4.

[0033] Working principle:

[0034] When the frozen food transport packaging box is in use, rotating the first operating lever 9 and the two bevel gears 10 will drive the first worm 8 to rotate. The rotation of the first worm 8 will drive the rotation of the first worm wheel 7. The rotation of the first worm wheel 7 will drive the rotation of the threaded connecting sleeve 6. At this time, the threaded rod 11 of the second worm 14 and the second worm wheel 13 will not rotate. Therefore, when the threaded connecting sleeve 6 rotates, it can drive the mounting block 3 and the placement plate 4 to move, thereby realizing the adjustment of the height of the placement plate 4.

[0035] Subsequently, rotating the second operating lever 15 will drive the rotation of the second worm gear 14, which in turn drives the rotation of the second worm wheel 13, thereby driving the rotation of the threaded rod 11. At this time, due to the self-locking property between the first worm gear 8 and the first worm wheel 7, the threaded connecting sleeve 6 will not rotate, thus enabling the two mounting blocks 3 to move simultaneously outside the threaded rod 11, thereby allowing the height of the two placement plates 4 to be adjusted simultaneously.

[0036] When disassembling or installing the placement plate 4, it is only necessary to make the inclined surface of the trapezoidal block 22 contact the mounting block 3. At this time, the trapezoidal block 22 can slide inside the sliding groove 21 with the help of the inclined surface. The return spring 23 will generate elastic deformation so that the trapezoidal block 22 can be inserted into the mounting block 3 after the slot on the surface of the mounting block 3 is aligned. After the trapezoidal block 22 is inserted into the mounting block 3, the plug screw 25 can be inserted into the slot 24 to achieve secondary fixation, thereby effectively ensuring the stability of the placement plate 4.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
