Description

Technical Field

[0001] The utility model relates to the field of educational toys for intellectual development, and particularly to an animation film projection toy. Background Art

[0002] A projector is a mechanical device that restores the images and sounds recorded on a film, in combination with a screen, an amplifier, etc. With the continuous development of technology, film projectors have gradually faded out of people's sight, but their important role in the film industry will not be forgotten by people. To facilitate children's understanding of film projectors, some science and technology museums still retain prototypes for children to visit. However, since they can only be viewed at close range and cannot be intuitively understood through manual operation of their working principles, it is difficult to learn about projectors. Content of the Utility Model

[0003] The purpose of the utility model is to provide an animation film projection toy to solve the problem in the above background art that it is difficult to learn about projectors because they can only be viewed at close range and cannot be intuitively understood through manual operation of their working principles.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an animation film projection toy, including a mounting plate, a driving component and a winding component;

[0005] Among them: a projection lens is installed on the surface of the mounting plate, and brackets are installed on both sides of the top of the mounting plate;

[0006] The driving component includes a mounting seat installed at the top of one of the brackets. A rotating rod is rotatably installed inside the mounting seat. One end of the rotating rod is fixedly installed with a driven gear. A transmission rod is rotatably installed on one side inside the mounting seat. A driving gear is fixedly installed on the surface of the transmission rod. The driving gear is meshed with the driven gear. One end of the transmission rod extends outside the mounting seat and is fixedly installed with a crank.

[0007] The winding component includes a winding disc installed at the other end of the rotating rod. The top of the other bracket is rotatably installed with a film reel, and a movie film is wound inside the film reel.

[0008] As a preferred scheme of the utility model: a ratchet is further installed on the surface of the transmission rod near the driving gear. A shifting rod is rotatably installed inside the mounting seat. One end of the shifting rod is installed with a pawl, and the pawl is inserted into the middle of the ratchet tooth groove.

[0009] As a preferred scheme of the utility model: a return spring is sleeved on the surface of the shifting rod.

[0010] As a preferred embodiment of the present utility model: the other end of the rotating rod is connected with a fixing screw, a threaded hole is formed in the middle of the winding disc, and the fixing screw is threadedly connected inside the threaded hole.

[0011] As a preferred embodiment of the present utility model: a plurality of guide wheels are installed on the surface of the mounting plate, and the motion picture film is wound around the surface of the guide wheels.

[0012] As a preferred embodiment of the present utility model: a protective cover is installed on one side of the mounting seat, and the protective cover covers the surface of the driven gear.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] (1) A mounting seat is installed at the top of one of the brackets. A rotating rod is rotatably installed inside the mounting seat. One end of the rotating rod is installed with a driven gear. Rotating the crank handle drives the transmission rod to rotate. The transmission rod rotates to drive the driven gear connected by meshing through the driving gear installed at one end. The driven gear drives the rotating rod to rotate, so as to drive the winding disc to rotate accordingly through the rotating rod, which is convenient for driving the film to realize continuous rolling and presenting a playing picture through the projection lens. This toy enables children to more intuitively understand its basic principle through manual operation, improving the learning fun.

[0015] (2) When the crank handle drives the transmission rod to rotate, the ratchet on the surface of the transmission rod rotates accordingly. The rotation of the ratchet drives the claw at one end of the lever to disengage from the tooth groove of the ratchet. At the same time, the lever is continuously driven by the force applied by the return spring to drive the claw to penetrate into the tooth groove of the ratchet. When the transmission rod stops rotating, the claw is engaged in the tooth groove of the ratchet to prevent the transmission rod from rotating, thereby avoiding the film from rewinding.

[0032] During specific use: The guide wheels 10 installed on the surface of the mounting plate 1 facilitate the winding and guiding of the movie film 53.

[0033] Please refer to Figure 2 , a protective cover 11 is installed on one side of the mounting seat 41, and the protective cover 11 covers the surface of the driven gear 43.

[0034] During specific use: The protective cover 11 on one side of the mounting base 41 covers the surface of the driven gear 43, playing a protective role to prevent children's hands from coming into contact with the driven gear 43 and causing harm.

[0035] A mounting base 41 is installed at the top of one of the brackets 3. A rotating rod 42 is rotatably installed inside the mounting base 41. One end of the rotating rod 42 is installed with a driven gear 43. Rotating the crank 46 drives the transmission rod 44 to rotate. The rotation of the transmission rod 44 drives the driven gear 43 that is meshed and connected through the driving gear 45 installed at one end to rotate. The driven gear 43 drives the rotating rod 42 to rotate, thereby driving the winding reel 51 to rotate along with the rotating rod 42, facilitating the continuous rolling of the film and presenting a playback image through the projection lens 2.
