[0005] In a preferred embodiment of this utility model, the base plate, the first positioning box, and the second positioning box are formed by folding cardboard into one piece.

[0006] In a preferred embodiment of this utility model, both the first positioning box and the second positioning box are bonded to the base plate.

[0007] In a preferred embodiment of the present invention, the base plate is provided with a plurality of box-shaped hollow positioning trays, and the top of the positioning trays is provided with an arc-shaped groove.

[0008] In a preferred embodiment of this utility model, the positioning tray is bonded to the base plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a large-displacement motorcycle crankshaft packaging box. The large-displacement motorcycle crankshaft packaging box solves the packaging problem during the transportation of the large-displacement motorcycle crankshaft through a specially made inner lining C, effectively avoiding the crankshaft collision problem that may occur during transportation. At the same time, compared with the traditional wooden box structure, the large-displacement motorcycle crankshaft packaging box can both ensure strength and reduce packaging costs.

Detailed Implementation

[0012] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0013] like Figures 1 to 4 As shown, the large-displacement motorcycle crankshaft packaging box includes a cardboard box Y and an inner liner C. The inner liner C includes a bottom plate 10. One end of the bottom plate 10 is provided with a box-shaped hollow first positioning box 20. The side wall of the first positioning box 20 is provided with a "U"-shaped first positioning opening 21. The other end of the bottom plate 10 is provided with a box-shaped hollow second positioning box 30. The side wall of the second positioning box 30 is provided with a "U"-shaped second positioning opening 31.

[0014] It should be noted that the base plate 10, the first positioning box 20, and the second positioning box 30 are integrally formed by folding cardboard. Alternatively, the first positioning box 20 and the second positioning box 30 are both bonded to the base plate 10.

[0015] The working method of the crankshaft packaging box for this large-displacement motorcycle is explained below.

[0016] like Figure 5 and Figure 6 As shown, crankshaft A is placed in carton Y, so that crankshaft step 2 of crankshaft A is engaged in the first positioning opening 21 of the first positioning box 20, and crankshaft diameter 3 of crankshaft A is engaged in the second positioning opening 31 of the second positioning box 30.

[0017] The large-displacement motorcycle crankshaft packaging box solves the packaging problem during the transportation of the large-displacement motorcycle crankshaft through a specially designed inner lining C, effectively avoiding possible crankshaft bumps during transportation. At the same time, compared with the traditional wooden box structure, the large-displacement motorcycle crankshaft packaging box can both ensure strength and reduce packaging costs.

[0018] like Figure 7 and Figure 8 As shown, this is another embodiment of the present invention. In this case, the base plate 10 is provided with a plurality of box-shaped hollow positioning trays 40, and the top of the positioning tray 40 is provided with an arc-shaped groove 41.

[0019] It should be noted that the positioning tray 40 is bonded to the base plate 10.

[0020] The positioning bracket 40 on the base plate 10 can effectively support the middle part of the crankshaft A, preventing the first positioning box 20 and the second positioning box 30 from collapsing, and can also restrict the lateral movement of the crankshaft A, further protecting the crankshaft A.

[0021] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
