Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

Referring to fig. 1, 2 and 3, the present invention provides a transportation packing box capable of being frozen twice, which comprises: the structure of the refrigerator comprises a refrigerator cover 1, a refrigerator body 2 and an inner box 3, wherein the refrigerator cover 1 is buckled at an opening of the refrigerator body 2, the inner box 3 is installed in the refrigerator body 2, a refrigeration cavity 4 is arranged between the inner walls of the inner box 3 and the refrigerator body 2, the refrigeration cavity 4 is communicated with the two ends and the bottom in the refrigerator body 2, ice placing plates 5 are arranged in the middle parts of the two ends in the refrigeration cavity 4, a plurality of water filtering holes 6 are formed in the ice placing plates 5, a trigger device 7 is arranged below the ice placing plates 5, a detachable freezing groove 8 is arranged in the middle part of the bottom end of the inner box 3, the bottom of the freezing groove 8 is positioned in the refrigeration cavity 4, a refrigerant 9 is contained in the freezing groove 8, an opening 10 is formed in the side wall of the freezing groove 8, the trigger device 7 is composed of a water containing groove 11, a guide rod 12 and a spring 13, the water containing groove 11 is slidably installed, the utility model discloses a refrigerator, including the ice board, including the guide bar 12, spring 13 cover establish with guide bar 12, hold basin 11 outside edge guide bar 12 slides, hold basin 11 inboard bottom seted up delivery port 15, hold basin 11 inboard top is equipped with fixture block 16, corresponding card hole 17 has been seted up to inner box 3 outside bottom, be equipped with slidable push rod 18 in the card hole 17, the push rod 18 other end extends to inside the inner box 3, be equipped with heat preservation 19 in the box 1, a plurality of through-holes 20 have been seted up to inner box 3 bottom, refrigerant 9 comprises 8% sodium bicarbonate, 12% biuret and 80% methylene diurea, it is half circular structure to put ice board 5.

For example, put the express delivery article in inner box 3 during the use, then place the ice-cube on putting ice sheet 5, the ice-cube carries out the refrigeration process for inner box 3, refrigerates the express delivery article, and then the ice-cube can be gradually melted along with time lapse, and the water after melting drips from drainage hole 6 in containing basin 11, and more along with the water is more, and the water weight in containing basin 11 is more and more, then drives containing basin 11 and moves down. When the delivery port on water containing groove 11 moves down and breaks away from the lateral wall of inner box 3, water can flow out from delivery port 15, simultaneously water containing groove 11 moves down the back fixture block can block the hole bayonet socket, thereby fixing water containing groove 11, avoid making water containing groove 11 reset because of the loss of water, when needing to reuse only need promote push rod 18 with fixture block 16 push away from the card hole can, then these water that flow out flow into in freezing groove 8 and refrigerant 9 reaction produce endothermic material, the express delivery article in inner box 3 freezes once more, the cold storage time of packing box has been improved.
