Next, fold the first interlayer 103 fixed to the left side piece 111 downward along the folded connecting edge c1 so that the first inner side piece 1031 overlaps the left side piece 111; fold the first inner bottom piece 1033 along the folded connecting edge c2 Fold upwards so that the first inner bottom sheet 1033 overlaps the bottom surface of the packaging box; fold the first support sheet 1034 upwards along the folded connection edge c3 so that the first support sheet 1034 is perpendicular to the first inner bottom sheet 1033; connect along the fold Fold the first cushioning sheet 1032 downwards at edge c4, so that the first buffering sheet 1032 is perpendicular to the first supporting sheet 1034; It is perpendicular to the ground of the packaging box; fold the first support bottom sheet 1036 upward along the folded connection edge c6, so that the first support bottom sheet 1036 overlaps with the bottom surface of the packaging box, and the bottom edge c7 coincides with the bottom edge of the right side sheet. Here, the heights of the first support sheet 1034 and the first support sheet 1036 are equal, so that the first buffer sheet 1032 is parallel to the bottom surface of the packaging box. That is, the first inner bottom sheet 1033 and the first supporting bottom sheet 1036 are against the bottom plate, the first support sheet 1034 and the first support sheet 1035 uprightly support the first buffer sheet 1032, and make the first buffer sheet 1032 and the bottom plate spaced apart from each other to form the first buffer sheet 1032. A storage space. Thereby, in the first accommodating space formed between the first buffer sheet 1032 and the bottom plate, relevant accessories of the product can be placed, such as the power supply of the product, connecting wires, etc. For the function of the following products, the first buffer sheet 1032 also becomes the bottom surface of the second accommodating space formed after the second accommodating area of the product in the second interlayer 102 is folded, and plays a supporting role. At this time, the assembled state of the packaging box is shown in FIG. 5 .

Next, fold the second inner sheet 1021 of the second interlayer 102 downward along the folded connection edge f1 so that the second inner sheet 1021 overlaps the right side sheet 113; Fold so that the second buffer sheet 1022 is parallel to the bottom surface of the packaging box. At this time, the folding groove on the second buffer sheet 1022 is folded to form a second accommodating space, that is, the groove on the second buffer sheet 1022 The first, second, third and fourth flaps 1023, 1024, 1025, 1026 are folded to form a second accommodating space, which can be used to place the host of the product, such as an electronic product with a liquid crystal display The host of the screen; then insert the tongue piece 1 into the first notch 2, so that the second interlayer 102 is located above the first interlayer 103, as shown in FIG. 6 .

Next, fold the third interlayer 101 downwards along the folded connection edge a1, so that the sealing sheet 1012 and the front side sheet 112 form a vertical state; fold the third support sheet 1013 downwards along the folded connection edge a2, so that the third support The sheet 1013 and the sealing sheet 1012 form a vertical state; the third buffer sheet 1011 is folded up along the folded connection edge a3, and at this time, the protruding sheet 5 is inserted into the opening 4 of the second inner sheet 1021 of the second interlayer 102, and the protruding Sheet 6 is inserted into the second notch 3 of the first inner sheet of the first interlayer 103, and the third buffer sheet 1011 is parallel to the bottom surface of the packaging box and fixed to a certain extent; The fifth support sheet 1014 is folded upwards, so that the fifth support sheet 1014 and the third buffer sheet 1011 form a vertical state. At the same time, the fifth support sheet 1014 overlaps with the rear side sheet 114. The state of the entire packaging box at this time is shown in Figure 7 .

Finally, insert the fastening piece 8 of the box cover 104 into the socket 9 of the sealing piece 1012 of the third interlayer, so far, the whole packaging box is completed, as shown in FIG. 8 .

As shown in Fig. 9, Fig. 10, Fig. 11 and Fig. 12, they are schematic diagrams of the second embodiment of the present invention. In order to increase the stability of the folded area on the second buffer sheet 1022 to form the second accommodating space, the The design of the second accommodating area of the product is subject to change. The following description only focuses on the structure that is different from that in the first embodiment, and the structure of the other parts that are the same will not be described in detail, nor will they be marked in the figure. The first plug-in piece 1025a and the second plug-in piece 1025b are respectively added to the first block piece 1023 and the second block piece 1024 in the second accommodation area, and at the same time, the third block piece 1025 and the fourth block piece 1026 are respectively formed The third and fourth plug-in pieces 1026a, 1026b. In addition, a circular through hole 10 is opened at the corresponding position in the middle of the first cushioning sheet 1032, and the left and right sides of the through hole 10 are respectively vertically provided with narrow and long rectangular through grooves 11, and the two through grooves 11 correspond to the first blocking piece 1023 and the second blocking piece The first plug-in piece 1025a and the second plug-in piece 1025b of the piece 1024 are inserted and received and respectively fixed to the first blocking piece 1023 and the second blocking piece 1024. In this way, after the second accommodating area is folded and formed along the scoring line, The supporting degree of the first blocking piece 1023 and the second blocking piece 1024 is enhanced. In addition, the user can conveniently pull the first interlayer 103 apart by holding the through hole 10 with his fingers.

To sum up, those skilled in the art can make various other corresponding changes and deformations according to the technical solutions and technical concepts of the present invention, and all these changes and deformations should belong to the scope of the present invention. the scope of protection of the claims.
