[0063] In one possible embodiment, Figure 3 As shown, the rotating projector toy includes a driving gear 6, which is rotatably mounted on the housing 1. The rotating body 21 includes a first gear portion 213, the driving gear 6 and the first gear portion 213 are meshed with each other, and the crank 4 is connected to the driving gear 6. Rotating the crank 4 can drive the driving gear 6 to rotate, and the rotation of the driving gear 6 can drive the rotating body 21 to rotate, thereby driving the annular film 5 mounted on the mating circular table 22 to rotate, so that the light outlet 11 projects different patterns on the film.

[0064] like Figure 4 and Figure 9 As shown, a synchronization post 61 is provided on one side of the driving gear 6 along the thickness direction. The crank handle 4 has a rotating cylinder 41, which is rotatably connected to the housing 1 and has a synchronization groove 411. The synchronization post 61 is inserted into the synchronization groove 411. The cross section of the synchronization post 61 can be a quadrilateral, and the synchronization groove 411 has the same shape as the synchronization post 61. The synchronization post 61 is inserted into the synchronization groove 411. Rotating the crank handle 4 causes the driving gear 6 to rotate synchronously.

[0065] like Figure 2 、 Figure 7 、 Figure 8 and Figure 10As shown, the housing 1 is provided with a through hole 12, the rotating cylinder 41 passes through the through hole 12, one end of a connecting member (not shown) passes through the driving gear 6 and is connected to the crank 4, and the other end of the connecting member is limited to the driving gear 6.

The light board 31 is inserted into the slot 131, and the light board 31 is partially located in the battery cavity, and is very close to the battery 8. The light board 31 can be conveniently electrically connected to the battery. The mating round table 22 limits the light board 31 to prevent the light board 31 from sliding out of the slide groove.

[0070] In one possible embodiment, Figure 1 、 Figure 3 、 Figure 11 and Figure 13 As shown, the rotating projector toy includes two film reels 7, both of which are rotatably mounted on the housing 1. The rotating disk 2 is in driving connection with each of the two film reels 7. Rotation of the rotating disk 2 drives the two film reels 7. The film reels 7 enable the rotating projector of this application to highly simulate the feeling of showing a real movie, providing a great play experience for children.

[0071] like Figure 1 and Figure 3 As shown, the film reel 7 is provided with a gear ring 71, and the rotating disk 2 is provided with a second gear portion 214.
