Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] As shown in the attached Figures 1 to 3 A film projection toy is shown, including an outer housing 1 and a projection film 2. The outer housing 1 is composed of a housing one 11 and a housing two 12 buckled together, and a projection film 2 is arranged between the housing one 11 and the housing two 12. A reserved hole 111 is penetrated through the housing of the housing one 11, and a crank handle 3 is arranged in the hole of the reserved hole 111, and the crank handle 3 is rotatably connected to the projection film 2. A projection chamber 4 is arranged at one end of the outer housing 1 close to the crank handle 3, and an LED lamp bead 131 is arranged on the inner side of the film body of the projection film 2 facing the projection chamber 4.

[0026] Among them: When the crank handle 3 is shaken by the user, it drives the projection film 2 arranged in the outer housing 1 to rotate synchronously, and then the film information on the projection film 2 is projected and played by using the lit LED lamp bead 131 through the projection chamber 4.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods, as Figures 1 to 7 shown, and the detailed description is as follows:

[0029] As a preferred embodiment, a film main guide wheel 21 and a film auxiliary guide wheel 22 are respectively connected to the inner side of the projection film 2, and the edges of the film body of the projection film 2 rotate with the wheel grooves of the film main guide wheel 21 and the film auxiliary guide wheel 22 as the rotation grooves. The main mounting shaft 121 and the auxiliary mounting shaft 122 are respectively arranged at the positions corresponding to the centers of the wheels of the film main guide wheel 21 and the film auxiliary guide wheel 22 on the inner side of the housing of the second housing 12. A triangular support 14 in the shape of a triangular leg is arranged at the bottom of the outer housing 1, and a convex lens 41 is arranged inside the projection chamber 4. Further, the film projection toy is stably placed at the required position by using the triangular support 14. Since the convex lens 41 is arranged inside the projection chamber 4, the picture during the projection of the projection film 2 is enlarged, and the projection area is further increased. And by virtue of the structural feature that the main mounting shaft 121 and the auxiliary mounting shaft 122 are respectively arranged at the positions corresponding to the centers of the wheels of the film main guide wheel 21 and the film auxiliary guide wheel 22, the projection film 2 rotates more smoothly during rotation, and the action of simulating a real film projector is more vivid.

[0030] As a preferred embodiment, a crank handle mounting hole 123 is reserved on the inner side of the housing of the second housing 12 corresponding to the crank handle 3. A battery compartment 13 is arranged on the side of the second housing 12 away from the first housing 11, and the battery compartment 13 is electrically connected to the LED lamp beads 131. Further, due to the auxiliary function of the crank handle mounting hole 123, the crank handle 3 will not shake additionally during shaking, and the user can shake the crank handle 3 smoothly, thereby driving the projection film 2 to rotate smoothly.

[0031] As a preferred embodiment, a plurality of groups of gear holes 23 are equidistantly arranged on the film body of the projection film 2. The crank handle 3 is composed of a crank handle rod 31, a plug-in rod 32 and a projection rod 33. An inner hexagonal plug-in hole is reserved at one end of the rod body of the crank handle rod 31. The plug-in rod 32 is inserted into the inner hexagonal plug-in hole, and a projection rod 33 that rotates synchronously with it is connected to the end of the plug-in rod 32 away from the crank handle rod 31. A plurality of groups of guide pins 331 are arranged at the position of the projection rod 33 relative to the gear holes 23. Further, due to the limiting effect of the inner hexagonal plug-in hole between the crank handle rod 31 and the plug-in rod 32, the force transmission process between the crank handle rod 31 and the plug-in rod 32 is more stable. And as the crank handle rod 31 and the plug-in rod 32 rotate, while driving the projection rod 33 and the guide pins 331 to rotate, the guide pins 331 are synchronously inserted into the corresponding gear holes 23. By virtue of the fitting effect between the gear holes 23 and the guide pins 331, the projection film 2 rotates smoothly as the crank handle 3 rotates.

[0032] The working process of the present utility model is as follows: First, use the triangular bracket 14 to stably place the film projection toy at the required position. While the crank 3 is being shaken by the user, it drives the synchronous rotation of the projection film 2 arranged inside the outer casing 1. Then, use the lit LED lamp beads 131 to project and play the film information on the projection film 2 through the projection chamber 4. Because a convex lens 41 is arranged inside the projection chamber 4, the picture during the projection of the projection film 2 is enlarged, and the projection area is further increased. As the crank lever 31 and the insertion rod 32 rotate, while driving the projection rod 33 and the guide pin 331 to rotate, the guide pin 331 is synchronously inserted into the corresponding gear hole 23. By the engagement between the gear hole 23 and the guide pin 331, the projection film 2 rotates smoothly with the rotation of the crank 3. Due to the structural features that the main installation shaft 121 and the secondary installation shaft 122 are respectively arranged at the center positions of the film main guide wheel 21 and the film secondary guide wheel 22, the projection film 2 rotates more smoothly during rotation, and the simulation of the action of a real film projector is more vivid. The above is the working principle of the film projection toy.
