DETAILED DESCRIPTION

[0027] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0028] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0029] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides a frozen food cold chain delivery box, including an insulated outer box 100, a heat-conducting inner box 200, a positioning ring plug 300 and a box cover 400.

[0030] A positioning groove 110 is provided on the upper side of the bottom wall of the heat-insulating outer box 100 .

[0031] The heat-conducting inner box 200 is adapted to be inside the heat-insulating outer box 100, and there is a fitting gap between the side wall of the heat-conducting inner box 200 and the heat-insulating outer box 100. The bottom of the heat-conducting inner box 200 is positioned in the positioning groove 110, and a plurality of side receiving grooves 210 are provided on the outer wall of the heat-conducting inner box 200. A side cold storage unit 220 is embedded in each side receiving groove 210. A convex ring 230 extending upward from the inner wall of the heat-conducting inner box 200 is provided at the upper end of the heat-conducting inner box 200.

[0032] The positioning ring plug 300 is embedded between the convex ring 230 and the heat-insulating outer box 100 .

[0033] The box cover 400 is provided on the heat-insulating outer box 100. Figure 1 One end of the box cover 400 is hinged to one side of the upper end of the thermal insulation outer box 100, and the other end of the box cover 400 is connected to the other side of the upper end of the thermal insulation outer box 100 through a lock 420. When the box cover 400 is closed, the lock 420 can be used to lock the box cover 400 to ensure that the box cover 400 is not opened during transportation.

[0034] The present application arranges the side cold storage unit 220 outside the heat-conducting inner box 200, and the heat-conducting inner box 200 is placed in the heat-insulating outer box 100. The heat-insulating outer box 100 has the function of heat preservation and heat insulation. The heat-conducting inner box 200 is used to hold frozen products. The side cold storage unit 220 can be transferred to the frozen products through the heat-conducting inner box 200, thereby cooling the frozen products. At the same time, during the distribution process, the side cold storage unit 220 will not directly contact the frozen products, which can prevent the frozen products from directly contacting the cold storage unit and causing the cold storage unit to be contaminated.

[0035] When the side cold storage unit 220 is taken out for cooling, the heat-conducting inner box 200 needs to be taken out from the heat-insulating outer box 100. In order to ensure that the heat-conducting inner box 200 can be smoothly taken out of the heat-insulating outer box 100, a certain gap needs to be maintained between the side wall of the heat-conducting inner box 200 and the heat-insulating outer box 100. However, if there is a gap between the side wall of the heat-conducting inner box 200 and the heat-insulating outer box 100, the heat-conducting inner box 200 will be unstable in the heat-insulating outer box 100. A positioning groove 110 is provided on the top to position the bottom of the heat-conducting inner box 200. A positioning ring plug 300 is provided between the upper ends of the heat-conducting outer box 100 and the heat-conducting inner box 200 to position the upper end of the heat-conducting inner box 200. This ensures that the heat-conducting inner box 200 is stably positioned in the heat-conducting outer box 100. When the heat-conducting inner box 200 needs to be lifted out of the heat-conducting outer box 100, the positioning ring plug 300 is first removed, and then the heat-conducting inner box 200 can be easily lifted out of the heat-conducting outer box 100.

[0036] In this embodiment, refer to Figure 1 and Figure 3 In order to facilitate lifting the thermal conductive inner box 200 after removing the positioning ring plug 300, the convex ring 230 is provided with openings 231 for fingers to insert. After removing the positioning ring plug 300, fingers can be inserted into the openings 231 on both sides of the thermal conductive inner box 200, so that it is convenient to apply force to the thermal conductive inner box 200 when lifting it.

[0037] In this embodiment, continue to refer to Figure 1 and Figure 3A boss 410 is provided on the inner side of the box cover 400. When the box cover 400 is closed, the boss 410 abuts against the upper side of the positioning ring plug 300. In this way, closing the box cover 400 can press the positioning ring plug 300 and the heat-conducting inner box 200, thereby further limiting the position of the heat-conducting inner box 200.

[0038] Preferably, a top receiving groove 411 is provided on the boss 410, and a top cold storage unit 412 is embedded in the top receiving groove 411, so that the frozen products in the heat-conducting inner box 200 can be further cooled by the top cold storage unit 412, thereby further improving the freezing effect of the frozen products.

[0039] Reference Figure 5 The side cold storage unit 220 and the top cold storage unit 412 both include a cold storage container 221 and a cold storage medium disposed in the cold storage container 221. The cold storage container 221 is provided with a medium injection port that can be opened and blocked. The cold storage medium can be water. Before use, the water in the cold storage container 221 is frozen into ice by a refrigerator, thereby achieving the effect of cold storage.

[0040] In order to facilitate opening and closing of the medium injection port, a threaded interface 222 protruding outward is provided at the medium injection port, and a sealing cover is externally connected to the threaded interface 222 .

[0041] In order to enable the cold storage container 221 to be better embedded in each receiving groove, the cold storage container 221 has a flat rectangular structure, and a recessed portion 223 is provided on one side of the cold storage container 221. The threaded interface 222 is provided in the recessed portion 223. When the sealing cover is tightened on the threaded interface 222, the top of the sealing cover does not protrude from the side of the cold storage container 221.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
