Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1-3, a packing box with a refrigeration function comprises a box body 1, wherein the top of the box body 1 is an open structure, a box cover 2 is in sliding contact with the top end of the box body 1, the box cover 2 is an inverted dish-shaped structure, and the box cover 2 is pressed down on the box body 1, so that food in the carton box is in a relatively closed space. The box body 1 comprises a paper board layer 3, a foam sandwich board 4 and a cooling water curtain 5, wherein the outer wall of the box body 1 is the paper board layer 3, so that when the box body 1 is vibrated in transportation and collides with the inside of a transport vehicle, the paper board layer 3 is soft and deformable, the inside of the transport vehicle cannot be scratched by a knife, the foam sandwich board 4 is bonded on the inner side of the paper board layer 3, foam can isolate high temperature outside the box, the inside of the box can be kept at low temperature, clamping plates on two sides of the foam are color steel tiles, the bearing capacity of the carton is improved, and the carton is firmer and can be repeatedly utilized for many times. One side of the foam sandwich board 4 far away from the paper board layer 3 is adhered with a cooling water curtain 5, the cooling water curtain 5 is connected with an elastic band 6, the stretching part of the elastic band 6 is positioned inside the carton, the ice bag is placed into the elastic band 6 on the inner side wall of the carton, the ice bag is fixed in position, the ice bag can be cooled and kept fresh from each side of the carton, the phenomenon that the carton shakes is avoided, the ice bag shifts, partial food cannot be fully contacted with low temperature, the food cannot keep enough fresh is avoided, and when the transportation time is long, the temperature in the box body 1 rises, the ice bag melts, crystals on the outer package of the ice bag melt, water drops into the cooling water curtain 5 and then contacts with the air in the box, the heat in the box is absorbed and evaporated, the temperature in the box is reduced, and the fresh-keeping time of the food in the.

2 outer walls of case lid are cardboard layer 3, 2 inner walls of case lid are foam battenboard 4, when case lid 2 is covered at 1 top of box, 2 inside foam battenboard 4 of case lid and the 3 sliding contact in cardboard layer of 1 outer wall of box, 1 box is provided with on being close to the open-ended lateral wall in top and moulds pole 7, mould pole 7 and fix on foam battenboard 4 outer wall, mould the pole 7 other end and wear out cardboard layer 3, upwards extended slide 8 has all been seted up to the foam battenboard 4 both sides bottom of 2 inner walls of case lid, round hole 9 has been seted up to 2 outer walls of case lid cardboard layer 3 both sides, round hole 9 internal rotation has eccentric wheel 10, eccentric wheel 10 can be tensile in case lid 2 horizontal direction, eccentric wheel 10 is located same horizontal plane with slide 8. 2 lid of case lid down before pushing down on 1 board of box, with eccentric wheel 10 to the pulling of 2 outer walls of case lid, push down the in-process, mould pole 7 and slide in slide 8, when case lid 2 covered tightly with 1 board of box, mould pole 7 and slide 8 top contact, promote eccentric wheel 10 to 2 inner walls of case lid, make and mould 7 one end and be located eccentric wheel 10, rotate eccentric wheel 10 again, can make and mould pole 7 and eccentric wheel 10 rigidity, make box 1 and case lid 2 fixed, it is better to make the sealed effect of incasement space.

The position of the ice bag on the inner side wall of the refrigerator is fixed, so that food is cooled uniformly, when the temperature in the refrigerator rises, crystals outside the ice bag packaging bag melt, water drips into the cooling water curtain 5, and the air in the refrigerator evaporates water on the cooling water curtain 5 to absorb heat in the refrigerator and reduce the temperature in the refrigerator body 1.

The working principle is as follows: put into each lateral wall elastic cord 6 internal fixation position of incasement with the ice bag, put the food that needs cold-stored fresh-keeping in box 1, before covering case lid 2, promote eccentric wheel 10 of case lid 2 both sides to case lid 2 outer wall direction, press down case lid 2 lid on box 1 again, the slide 8 that the pole 7 was seted up in case lid 2 inside of moulding of box 1 both sides slides, after case lid 2 covered tightly with box 1, mould pole 7 and be located the slide 8 top, promote eccentric wheel 10 to moulding pole 7 direction, make and mould pole 7 one end and be located eccentric wheel 10, rotate eccentric wheel 10, can make case lid 2 and box 1 fixed. The carton is in the transportation, and when the incasement temperature rose, the outer crystallization of ice bag wrapping bag began to melt, and on the water drop fell cooling cascade 5, the incasement air contacted with the water on the cooling cascade 5, absorbed the incasement heat, reduced incasement temperature, made the fresh-keeping effect of incasement food better.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature.
