[0002] Packaging boxes are a common packaging tool used in logistics to transport various products. Typically, a paper insert is placed inside the packaging box to hold the product in place and prevent it from shaking.

[0003] For example, the inner tray assembly disclosed in Chinese utility model CN221068845U is made of paper material and is used to load a magnetic levitation Bluetooth speaker. It includes a first inner tray and a second inner tray, both of which are made of multiple folded paper panels.

[0004] However, the inventors discovered during the actual research and development process that the first inner tray and the second inner tray were both folded into a square structure, and the first inner tray and the second inner tray were respectively set with a first cavity and a second cavity. Such a structure would waste a lot of paper material; moreover, the square structure of the paper tray was prone to cracking at the corners, edges and surfaces during the reliability drop test, which showed that its cushioning and shock absorption performance was very poor.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a paper-formed packaging box for cylindrical electronic products, effectively solving the technical defects of existing packaging boxes with paper inner tray components, which have paper material waste and poor cushioning and shock absorption performance.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] Please refer to the following: Figures 1 to 14 The paper-molded packaging box 10 for cylindrical electronic products provided in this application embodiment will now be described. The paper-molded packaging box 10 for cylindrical electronic products includes: a base plate 11, a connecting plate 12, and a top plate 13.

[0052] The connecting plate 12 is integrally formed on the base plate 11, and the top plate 13 is integrally formed on the front end of the connecting plate 12. Triangular buffer structures 14 are provided on the left and right sides of the base plate 11 and the top plate 13. When the connecting plate 12 is folded upward and backward relative to the base plate 11, and the top plate 13 is folded downward and backward relative to the connecting plate 12, the top plate 13 and the base plate 11 are spaced vertically and together with the multiple triangular buffer structures 14 to form a receiving cavity 101 for placing the cylindrical electronic product 100.

[0053] Specifically, the base plate 11, connecting plate 12, and top plate 13 are integrally formed, and both sides of the base plate 11 and top plate 13 are provided with triangular buffer structures 14 that can enclose and accommodate the cavity 101 to accommodate cylindrical electronic products. On the one hand, there is no need to set up an additional inner support structure, which can reduce the waste of paper materials; on the other hand, the triangular buffer structure 14 strengthens the support of the product, and its edges, corners, and surfaces have good stress relief space for acceleration impact, which can provide good cushioning and shock absorption performance for cylindrical electronic products.

[0054] Please refer to the following: Figures 1 to 6 In some embodiments of this application, the triangular buffer structure 14 is integrally formed on the left side of the base plate 11, the first buffer portion 1401, the second buffer portion 1402, the third buffer portion 1403, the left side of the top plate 13, and the fourth buffer portion 1404, and the structure of the first buffer portion 1401, the second buffer portion 1402, the third buffer portion 1403, and the fourth buffer portion 1404 are the same.

[0055] When the connecting plate 12 is folded upward and backward relative to the bottom plate 11, and the top plate 13 is folded backward and downward relative to the connecting plate 12, the connecting plate 12 can be perpendicular to the front end of the bottom plate 11, and the top plate 13 can be perpendicular to the connecting plate 12 and parallel to the bottom plate 11. At this time, the first buffer part 1401 and the second buffer part 1402 of the bottom plate 11 are arranged upward, and the third buffer part 1403 and the fourth buffer part 1404 of the top plate 13 are arranged downward. The bottom of the third buffer part 1403 can abut against the top of the first buffer part 1401, and the bottom of the fourth buffer part 1404 can abut against the top of the second buffer part 1402, so that the bottom plate 11, the connecting plate 12, the top plate 13, the first buffer part 1401, the second buffer part 1402, the third buffer part 1403 and the fourth buffer part 1404 enclose a receiving chamber 101 for placing cylindrical electronic products.

[0056] Since the first buffer section 1401, the second buffer section 1402, the third buffer section 1403 and the fourth buffer section 1404 have the same structure, the structure and folding method of the first buffer section 1401 will be specifically explained here.

By swaying the fourth support plate 144, it can be offset toward the center of the receiving chamber 101. When the cylindrical electronic product is installed in the receiving chamber 101, the fourth support plate 144 can be swayed outward, and the fourth support plate 144 can further provide support for the cylindrical electronic product, thereby making it less likely for the cylindrical electronic product to move after being installed in the receiving chamber 101, thus improving the reliability of the paper-molded packaging box 10.

[0059] Preferably, the upper surface of the third support plate 143 is provided with a first adhesive layer 1431.
