One end of the vertical profile strip 13 is welded to the connecting profile 14, and one end of the horizontal profile strip 12 is welded to the connecting profile 14. The connecting profiles 14 reduce the difficulty of welding the connection between the vertical profile strips 13 and the horizontal profile strips 12 and improve the processing efficiency.

[0022] Please refer to it again. Figure 1 , Figure 2 and Figure 3Both ends of the movable housing 3 are slidably connected to movable pipes 4 that communicate with the movable housing 3. The movable pipes 4 are annular tubes. The movable housing 3 and the connecting pipe 41 are connected by a connecting hose 31. The cold air inside the movable housing 3 is delivered to the interior of the movable pipe 4 through the connecting hose 31. Both ends of the movable housing 3 are slidably connected to connecting slide rods 42. The movable pipe 4 is fixedly connected to the bottom of the connecting slide rods 42. The connecting slide rods 42 support the movable pipe 4 to slide horizontally up and down at one end of the movable housing 3. There are multiple connecting pipes 41 fixedly connected to the movable pipe 4. All the multiple connecting pipes 41 are connected to the movable pipe 4. Multiple nozzles are opened on the movable pipe 4 and the connecting pipes 41. The cold air delivered to the interior of the movable pipe 4 is finally sprayed out through the nozzles on the movable pipe 4 and the connecting pipes 41 and blown into the interior of the refrigerated compartment 1.

[0023] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The movable housing 3 has a drive groove, and a rotating gear 5 is rotatably connected inside the drive groove. A connecting rod 51 is rotatably connected to one side of the rotating gear 5, and the other end of the connecting rod 51 is hinged to the movable tube 4. A fixed rack 6 that meshes with the rotating gear 5 is fixedly connected to the inner top wall of the refrigerated compartment 1. When the movable housing 3 slides horizontally, the rotating gear 5 is driven to rotate under the meshing action of the rotating gear 5 and the fixed rack 6. Under the connecting action of the connecting rod 51, the movable tube 4 is pulled to slide up and down at one end of the movable housing 3.

Figure 1 , Figure 2 , Figure 3 and Figure 5 A fixed slide rail 7 is fixedly connected to the inner top wall of the refrigerated compartment 1, and a sliding block 33 is fixedly connected to the top of the movable shell 3. The sliding block 33 slides inside the fixed slide rail 7. A rotating screw 71 is rotatably connected inside the fixed slide rail 7. The sliding block 33 is threadedly connected to the rotating screw 71. A motor 72 that drives the rotating screw 71 to rotate is fixedly connected to the inner top wall of the refrigerated compartment 1. By starting the motor 72, the rotating screw 71 is driven to rotate inside the fixed slide rail 7. Under the action of the sliding block 33, the movable shell 3 is driven to slide horizontally on the inner top wall of the refrigerated compartment 1, and the longitudinal section of the sliding block 33 is T-shaped.

[0025] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9The inner bottom wall of the refrigerated compartment 1 is fixedly connected with multiple support bars 11. A ventilation groove is formed between each pair of adjacent support bars 11. The support bars 11 support the bottom of the goods and allow cold air to flow between the ventilation grooves, so that the cold air can circulate from the bottom of the goods. The opening end of the refrigerated compartment 1 is hinged with a door 15. The two doors 15 are inlaid with sealing strips 16 at the ends that are close to each other. The sealing strips 16 are made of PVC material, which is one of the commonly used materials for sealing strips of refrigerated trucks. Its advantages are moderate cost and easy processing.

[0026] Working principle: By activating the refrigeration component 2, cold air is delivered into the interior of the movable housing 3 through the connecting telescopic pipe 21. The cold air inside the movable housing 3 is then delivered to the interior of the movable pipe 4 through the connecting hose 31, and finally sprayed out through the nozzles on the movable pipe 4 and the connecting pipe 41. The starting motor 72 drives the rotating screw 71 to rotate, and the sliding block 33 causes the movable housing 3 to slide horizontally on the inner top wall of the refrigerated compartment 1. During the horizontal sliding process, the movable housing 3 is driven to rotate by the meshing of the rotating gear 5 and the fixed rack 6. Under the connection of the connecting rod 51, the movable pipe 4 is driven to slide up and down at one end of the movable housing 3, so that the cold air is evenly distributed to all corners of the compartment.
