Description

A waterproof logistics box

technical field

The utility model relates to the technical field of logistics, in particular to a waterproof logistics box.

Background technique

The concept of logistics was first formed in the United States, originated in the 1930s, and originally meant "physical distribution" or "goods distribution". Introduced to Japan in 1963, it means "circulation of things" in Japanese. After the 1970s, the word "logistics" in Japan gradually replaced "the circulation of materials".

In logistics, some items that need to be refrigerated may sometimes need to be transported, but in the long-distance transportation process, dry ice is generally used for refrigeration. Dry ice needs to be in a sealed environment to reduce its volatilization rate and prolong the refrigeration time. Therefore, Generally, dry ice is placed directly in the transport box with the transported object.

The existing transport box itself does not have the ability to automatically reduce the air pressure, so this leads to the increase of the air pressure inside the transport box after the dry ice volatilizes in the transport box. Then the transport box will be crushed, and the heavy one will explode.

(3) Beneficial effects

Compared with the prior art, the utility model provides a waterproof logistics box, which has the following beneficial effects:

1. The waterproof logistics box is equipped with a bar block. When the dry ice is vaporized, the air pressure inside the shell increases. When the air pressure increases to a moving level, the bar block will be pushed up, and then vaporized. The dry ice is discharged from the bar opening to reduce the air pressure inside the housing. When the bar is flipped upward, the upper wall of the bar will touch the front wall of the limit block. At this time, the bar is inclined. After the internal air pressure is reduced, the bar-shaped block will move down again due to gravity, blocking the bar-shaped opening. This setting can make the utility model have the ability to automatically reduce the air pressure, and avoid the air pressure inside the casing reaching a certain level. When the pressure is reduced, the outer casing is broken, and after the air pressure is reduced, the bar-shaped block can be automatically closed to achieve the function of automatic decompression without the need for people to be by the side.

2. The waterproof logistics box is provided with grooves, and the inner walls of the front and rear sides of the groove are inclined from the side that is far away from each other to the side that is gradually approaching, so the internal air pressure will gather from the top of the groove, and then impact, and since the uppermost inner wall of the groove is the area where the strip plate is located, this arrangement makes it easier for the air pressure inside the casing to punch the strip block apart, and it is easier to discharge the vaporized dry ice.

3. The waterproof logistics box is provided with grooves. After the dry ice is vaporized, the temperature of the jaws inside the shell will decrease, and then the air inside will be liquefied and attached to the surface of the shell, and then the liquefied water will follow the grooves. The inclined surface of the radiator flows all the way to the gap between the shell and the placing block. This setting can facilitate the collection of liquefied water and avoid random dripping of water. Then, by rotating the rotating block, the rotating block is removed from the threaded pipe. The front and rear water will be discharged through the threaded pipe.
