DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] The present application provides a heat-preservation packaging carton, as shown in Figure 1 Figure 2 Figure 3 Figure 4 and Figure 5 The heat-preservation packaging carton comprises a bottom plate 1, a front end plate 2 fixedly installed on the bottom plate 1, a rear end plate 3 fixedly installed on the bottom plate 1, a left side plate 4 fixedly installed on the bottom plate 1, a right side plate 5 fixedly installed on the bottom plate 1, a top plate 6 fixedly installed on the rear end plate 3, and a plug-in mechanism arranged on both sides of the bottom plate 1 for facilitating recycling of used packaging cartons.

[0026] The plug-in mechanism comprises plug blocks 7 fixedly installed on the left side plate 4 and the right side plate 5, plug slots 8 opened on the bottom plate 1 for plug-in of the plug blocks 7, fixed plates 9 fixedly installed on the top plate 6, and support wing plates 10 fixedly installed on the fixed plates 9.

[0027] The plug blocks 7 are fixedly connected to the left side plate 4 and the right side plate 5 away from the bottom plate 1, the four sides of the plug blocks 7 are attached to the interiors of the plug slots 8, and the support wing plates 10 are provided in two, and are fixedly connected to both sides of the fixed plates 9, respectively.

[0028] ​​​​The heat-preservation packaging carton in use, first, the bottom plate 1 is placed in a suitable position, then the front end plate 2 and the rear end plate 3 are manually folded upwards along the inner folding crease line perpendicular to the bottom plate 1, then the left side plate 4 and the right side plate 5 are manually folded upwards along the inner folding crease line perpendicular to the bottom plate 1, then the left side plate 4 and the right side plate 5 perpendicular to the bottom plate 1 are manually folded downwards along the middle crease line perpendicular to the bottom plate 1, finally the insertion block 7 on the left side plate 4 and the right side plate 5 is inserted into the insertion slot 8, so that the left side plate 4 and the right side plate 5 remain perpendicular, and after folding, the left side plate 4 and the right side plate 5 and the bottom plate 1 form two compact spaces, then the top plate 6 is folded along the crease line between the top plate 6 and the rear end plate 3 until the top plate 6 is attached to the top of the front end plate 2, then the fixing plate 9 is folded along the crease line between the top plate 6 until the inner side of the fixing plate 9 is attached to the front end plate 2, then the two support wing plates 10 are inserted into the two compact spaces between the left side plate 4 and the right side plate 5 and the bottom plate 1, so that the packaging carton achieves a stable state, after use, only the two support wing plates 10 are extracted from the middle of the two compact spaces, then the insertion block 7 is pulled out of the insertion slot 8, so that the front end plate 2, the rear end plate 3, the left side plate 4, the right side plate 5 and the top plate 6 can be folded in the opposite direction, so that the packaging carton can be unfolded, which can improve the secondary use rate of the packaging carton, reduce the consumption of packaging carton materials, thereby reducing waste and further improving resource utilization efficiency.

[0029] Further, in order to heat preservation inside the packaging carton, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the bottom plate 1, the front end plate 2, the rear end plate 3, the left side plate 4, the right side plate 5 and the top plate 6 are fixedly connected with a plurality of support ribs 11 on one side, and the support ribs 11 are staggered.

[0030] The bottom plate 1, the front end plate 2, the rear end plate 3, the left side plate 4, the right side plate 5 and the top plate 6 are fixedly connected with a plurality of support ribs 11 on one side, and the support ribs 11 are staggered.

[0031] The heat-preservation packaging carton in actual use, by virtue of the setting of the support rib 11, can make the bottom plate 1, the front end plate 2, the rear end plate 3, the left side plate 4, the right side plate 5 and the top plate 6 of the packaging carton maintain a certain hardness, so that when the packaging carton is used, it can effectively prevent the packaging carton from collapsing, and because the heat preservation plate 12 is provided, it can well play a heat preservation role for the goods in the packaging carton.

[0032] It should be noted that, in order to seal the packaging box, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the two sides of the top plate 6 are fixedly connected with sealing flaps 13, and the two sides of the rear end plate 3 are fixedly connected with first connecting flaps 14.

[0033] The two sides of the front end plate 2 are fixedly connected with second connecting flaps 15.

[0034] When using this heat-insulating packaging carton, first, the front end plate 2, the rear end plate 3, the left side plate 4 and the right side plate 5 are erected by means of the plug-in mechanism. Then it can be seen that the two sealing flaps 13 installed on the top plate 6 will tightly adhere to the left side plate 4 and the right side plate 5, and the second connecting flaps 15 installed on the two sides of the front end plate 2 and the first connecting flaps 14 installed on the two sides of the rear end plate 3 will be inserted between the left side plate 4 and the right side plate 5 and between them and the bottom plate 1 to form two compact internal spaces, which can effectively ensure the sealing effect while ensuring the stability of the entire structure.

[0035] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
