[0028] On the basis of the above structure, the positioning assembly 6 includes a threaded rod 61, a movable block 62, a pull rod 63, a positioning column 64 and a guide groove 65. The threaded rod 61 is connected to the side wall of the box body 1 by a bearing. The outer side of the threaded rod 61 is threadedly sleeved with the movable block 62. The outer side of the movable block 62 is rotatably connected to the pull rod 63. The longitudinal section of the pull rod 63 is "L"-shaped, and the bottom end thereof is fixedly connected to the positioning column 64. A guide groove 65 is provided in the middle of the pull rod 63.

[0029] In this embodiment, the threaded rod 61 is used to control the movable block 62 to drive the pull rod 63 to perform lifting and lowering adjustment, so as to facilitate the convenient disassembly and assembly between the box body 1 and the ice storage box assembly 7.

[0030] On the basis of the above structure, the guide sliding of the cross bar 5 is located inside the guide groove 65. The guide groove 65 includes a vertical section and an inclined section located at the top of the vertical section. The inclined section is connected to the vertical section.

[0031] In this embodiment, the guide groove 65 is provided to facilitate the control of the rotation and stable vertical movement of the pull rod 63 .

[0032] On the basis of the above structure, the ice storage box assembly 7 includes a box body 71, an insulating pad 72, a support 73, a sealing pad 74, a connecting block 75 and a through hole 76. The bottom end of the box body 71 is bonded with the insulating pad 72, and a plurality of support pillars 73 are evenly distributed on the inner bottom of the box body 71. The upper end of the box body 71 is bonded with the sealing pad 74. The middle outer walls on the left and right sides of the top of the box body 71 are fixed with connecting blocks 75, and a through hole 76 is opened inside the connecting block 75.

[0033] In this embodiment, the external ice storage box assembly 7 is used to facilitate timely addition of ice cubes, thereby ensuring that the turnover box can still ensure good low-temperature preservation of food during long-distance transportation.

[0034] On the basis of the above structure, the height of the support 73 is equal to the internal height of the box body 71, and the top of the box body 71 and the bottom of the box body 1 are provided with a stepped structure that engages with each other.

[0035] In this embodiment, the top of the box body 71 and the bottom of the box body 1 are provided with a stepped structure that engages with each other, so as to facilitate quick and stable engagement between the two and facilitate installation of the box body 71 at the bottom of the box body 1.

[0036] On the basis of the above structure, the diameter of the through hole 76 is equal to the diameter of the positioning column 64 , and the positioning column 64 is plugged into the connecting block 75 through the through hole 76 .

[0037] In this embodiment, the through hole 76 is used to facilitate the insertion of the positioning column 64 and the connecting block 75, thereby facilitating the positioning of the pull rod 63, so that the pull rod 63 can pull the connecting block 75 upward to facilitate a stable and sealed connection between the box body 71 and the box body 1.

[0038] On the basis of the above structure, the isolation cavity 8 is communicated with the interior of the box body 71 .

[0039] In this embodiment, the isolation chamber 8 is provided to facilitate the entry of cold air emitted by ice cubes inside the box body 71, which can play a good temperature isolation role and facilitate the proper preservation of cold chain food.

[0040] The working principle of the utility model is as follows:

[0041] When in use, first place ice cubes in the box body 71, then snap the box body 71 into place at the bottom of the box body 1, and then manually rotate the threaded rod 61 to control the ice cubes. Figure 3 The movable block 62 shown in the figure drives the pull rod 63 to move upward synchronously. At this time, the cross bar 5 can squeeze the top inclined section of the guide groove 65, so that the pull rod 63 can move upward and rotate toward the box body 1. When the cross bar 5 enters the vertical section of the guide groove 65, the pull rod 63 is in a vertical state. At this time, the movable block 62 can drive the vertical pull rod 63 to move upward stably, and the positioning column 64 can be plugged into the connecting block 75 through the through hole 76, and as it continues to move upward, the connecting block 75 and the box body 71 can be moved upward. The box body 71 is pressed tightly, which facilitates the stable connection between the box body 71 and the box body 1. At the same time, the sealing gasket 74 can be used to ensure the sealing of the connection between the box body 71 and the box body 1. After the box body 71 is installed, the food can be put into the storage cavity 9 in the box body 1, and then the box cover 2 is closed, and the existing lock 3 is used to limit the box cover 2. The inside of the box body 71 is connected with the isolation cavity 8 inside the box body 1, which facilitates the cold air emitted by the ice cubes to diffuse around the storage cavity 9, play a good temperature isolation role, and facilitate the proper preservation of cold chain food;

[0042] During long-distance transportation, when the ice cubes in the box body 71 melt, the threaded rod 61 can be reversed to control the movable block 62 and the pull rod 63 to move vertically downward. When the positioning column 64 is separated from the connecting block 75, the pull rod 63 can be rotated and opened while moving downward, which is convenient for the overall disassembly of the external ice storage box assembly 7, and the ice cubes can be conveniently added and supplemented without opening the box cover 2, which is convenient for maintaining a stable low temperature state in the box body 1 and facilitating the proper storage of food. In addition, the multiple pillars 73 evenly distributed on the inner side of the box body 71 can also support the bottom of the storage cavity 9 to avoid deformation.

[0043] It should be noted that the lock 3 is an existing product, and its specific internal structure is completely consistent with the existing technology, so it will not be described in detail.

[0044] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
