[0020] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.
[0021] like Figure 1-Figure 4 As shown, this embodiment provides a corrugated paper box with a heat preservation function, including a paper box body 1, a heat preservation frame 2 and a receiving frame 3.
[0022] The carton body 1 has a mounting groove, and an upper cover plate 11 is provided around the opening of the carton body 1 .
[0023] The insulation frame 2 is located in the installation groove, and the upper surface of the insulation frame 2 has an insulation groove. The side walls and bottom walls of the insulation groove have multiple spaced partitions 22. The height of the partition 22 is set according to actual needs. The bottom plate of the insulation frame 2 is supported by a plastic plate body. The rest of the insulation frame 2 can be made of corrugated cardboard or plastic board. The use of corrugated cardboard can greatly reduce the production cost of the corrugated box. In this solution, the side plates made of corrugated cardboard and the bottom plate of plastic material are bonded by glue; the adjacent partitions 22 are filled with insulation fillers 4, which are insulation cotton or rock wool board or foamed polyurethane board. In this solution, insulation cotton is used. The thickness of the insulation filler 4 is greater than the height of the partition 22, so that the corrugated box has a certain distance of buffer distance, so that it has a seismic function. Two bosses 21 are formed at the bottom of the insulation groove. The boss 21 is located between the partitions 22. The boss 21 has a connecting hole 211, and the insulation filler 4 at the bottom has a through hole.
[0024] The object receiving frame 3 is located in the heat preservation groove and between the partitions 22. The opening of the object receiving frame 3 is surrounded by an extension plate 33 extending outward. The width of the extension plate 33 is equal to the distance between the outer wall of the carton body 1 and the object receiving frame 3. The bottom plate of the object receiving frame 3 is made of plastic material, and the side plate of the object receiving frame 3 is made of corrugated cardboard. The extension plate 33 is connected to the upper surface of the heat preservation frame 2 by gluing. When the side plates of the object receiving frame 3 and the heat preservation frame 2 are made of plastic material, the extension plate 33 is connected to the upper surface of the heat preservation frame 2 by fasteners. The lower surface of the object receiving frame 3 has a positioning column 31, the positioning column 31 passes through the connecting hole 211, and the lower end surface of the positioning column 31 has a round table 311, the diameter of the round table 311 is larger than the diameter of the connecting hole 211, and the spring 32 is sleeved on the positioning column 31, the upper surface of the spring 32 is in contact with the bottom of the object receiving frame 3, and the lower surface of the spring 32 is in contact with the upper surface of the boss 21 of the heat preservation frame 2. Specifically, the lower end of the positioning column 31 has an external thread, and the cone 311 is a nut, which is screwed together with the external thread. The reason for setting the spring 32 is to enhance the anti-seismic function of the corrugated cardboard box in the up and down directions. Since the objects are affected by gravity, when the objects are placed on the bottom of the receiving frame 3, the thermal insulation filler 4 will be compressed, which will reduce the anti-seismic effect of the thermal insulation filler 4 at the bottom. The spring 32 can make up for the reduced anti-seismic effect of the thermal insulation filler 4 and can further enhance the anti-seismic function of the corrugated cardboard box in the up and down directions.
[0025] The corrugated cardboard box in the present scheme includes a carton body 1, an insulation frame 2 and a receiving frame 3. A complete corrugated cardboard box is formed by embedding the insulation frame 2 and the receiving frame 3 in the carton body 1. A plurality of partitions 22 are arranged between the side wall and the bottom wall of the insulation frame 2, and insulation fillers 4 are filled between the plurality of partitions 22. When the three are spliced together, the corrugated cardboard box has the function of insulation, and the bottom plates of the insulation frame 2 and the receiving frame 3 are made of plastic plates to ensure that when items are placed in the receiving frame 3, the bottoms of the insulation frame 2 and the receiving frame 3 will not collapse, and the insulation fillers 4 and springs 32 between the insulation frame 2 and the receiving objects can also play an anti-seismic effect.
