Technical Field

[0001] The utility model relates to the technical field of early childhood enlightenment teaching aids, in particular to a music enlightenment teaching aid for early childhood. Background Art

[0002] Children's music enlightenment teaching aids are tools that help children get in touch with and learn music. These teaching aids can cultivate children's interest in music and develop their musical perception, sense of rhythm and auditory skills. Music boxes are children's music enlightenment teaching aids commonly used in existing families.

[0003] In the prior art, a Chinese patent document with publication number CN219696067U proposes a music box, which includes a sound-generating device and a pause device. The sound-generating device has a spring, a sound cylinder and a sound comb. The spring can rotate so that the sound comb can be hit by the sound cylinder to produce sound, and the pause device has a guide sleeve, a stopper, a push button, a guide assembly and a return spring, wherein the guide sleeve is provided with a plurality of initial positioning parts, a plurality of stop positioning parts and a connecting part, and the stopper is movably assembled on the guide sleeve and has a stopper block that can move between the initial positioning part, the stop positioning part and the connecting part. In addition, the push button can push the stopper to move along the positive direction, and the guide assembly The component can drive the stopper to rotate, and the return spring can push the stopper to move in the reverse direction. Thereby, the stopper can move into the initial positioning part or the stop positioning part in turn by pushing the button, the guide component and the return spring, so that the stopper can prevent the mainspring from rotating.

[0027] like Figure 1-Figure 6As shown, a teaching aid for music enlightenment for young children comprises a driving rod 2 and a driving member 7 mounted on a music box base 1, the driving rod 2 is meshedly connected with the driving member 7, one end of the driving rod 2 is provided with a turning handle for rotating the driving rod 2, a spiral groove is provided on the middle outer wall of the driving rod 2, the driving rod 2 is meshedly connected with the driving member 7 through the spiral groove in the middle, one end of the driving member 7 is fixedly connected with a sound cylinder 4, a sound combing plate 5 is slidably connected to one side of the upper end of the music box base 1, both sides of the middle part of the lower end of the sound combing plate 5 are fixedly connected with sliders 15, the lower ends of the two sliders 15 are provided with a clamping assembly for limiting the movement of the sound combing plate 5, and the clamping assembly consists of a limit block 9, The limit block 9 is composed of a card rod 8 and a double hook spring 13, and a card slot for limiting the movement of the card rod 8 is also opened at the upper end of the limit block 9, a positioning column 14 is fixedly connected to the middle of one end surface of the limit block 9, one end of the double hook spring 13 is sleeved on the positioning column 14, and the end of the double hook spring 13 away from the positioning column 14 is connected to the music box base 1, a positioning column 14 is fixedly connected to the middle of one end surface of the limit block 9, one end of the double hook spring 13 is sleeved on the positioning column 14, and the end of the double hook spring 13 away from the positioning column 14 is connected to the music box base 1, one end of the card rod 8 is slidably connected to the inside of the card slot, and the end of the card rod 8 away from the card slot is rotatably connected to the inside of the music box base 1. When the music box is in use, the driving rod 2 is rotated by the crank, and the driving rod 2 drives the driving member 7 to rotate, thereby rotating the sound cylinder 4, and the convex point on the upper end of the sound cylinder 4 plucks the sound comb to make a sound. When the music box is not in use, by pulling the pull rod 6, one end of the clamping rod 8 cancels the clamping connection with the second clamping groove 11 and slides out from the third clamping groove 12, and the limiting block 9 moves to the rear end by the action of the double hook spring 13, so that the front end of the sound comb plate 5 does not contact the sound cylinder 4. Pushing the pull rod 6 will make one end of the clamping rod 8 slide from the first clamping groove 10 into the second clamping groove 11, completing the limiting work of the clamping rod 8. At this time, the front end of the sound comb plate 5 contacts the sound cylinder 4, and the music box can be used again. Through this structural design, the problem that the sound quality changes when the music box is not in use due to the deformation of the front end of the sound comb in contact with the sound cylinder can be solved, thereby improving the practical performance of the music box.

[0028] Further, such as Figure 3 As shown, a non-return card plate is provided at one end of the driving member 7, and the lower end of the non-return card plate is fixedly connected to the music box base 1, and a non-return ratchet plate is fixedly connected to one end of the sound cylinder 4, and the non-return card plate is engaged with the non-return ratchet plate. Through the engagement of the non-return card plate with the non-return ratchet plate, the sound cylinder 4 can only rotate counterclockwise, and the convex point on the sound cylinder 4 can only move the sound comb from bottom to top, thereby emitting a good sound quality effect, thereby improving the music enlightenment effect on young children.

[0029] Further, such as Figure 5 , Figure 6As shown, the card slot is composed of a first card slot 10, a second card slot 11 and a third card slot 12, and the first card slot 10, the second card slot 11 and the third card slot 12 are all connected. The depth of the first card slot 10 is from shallow to deep, the depth of the second card slot 11 is slightly deeper than the deepest part of the first card slot 10, and the deepest part of the third card slot 12 is slightly the same as the second card slot 11. The depth of the third card slot 12 is from deep to shallow, and the shallowest depth of the first card slot 10 is slightly lower than the shallowest depth of the third card slot 12. Through the connection, the card rod 8 can slide freely inside it and return to the initial position. The different depths enable the card rod 8 to slide from the first card slot 10 into the second card slot 11 when it is pulled for the first time, and the second card slot 11 slides into the third card slot 12 and returns to the initial position when it is pulled again.

[0030] Further, such as Figure 1 As shown, both ends of one side of the upper end surface of the music box base 1 are provided with slide grooves 16, and the slider 15 is slidably connected inside the slide groove 16. The sliding connection can greatly improve the stability of the comb plate 5 when moving.

[0031] Further, such as Figure 1 As shown, a pull rod 6 is fixedly connected to the middle part of one side of the upper end surface of the sound combing plate 5. The convenience of moving the sound combing plate 5 can be greatly improved by setting the pull rod 6.

[0032] Further, such as Figure 1 As shown, a protective cover 3 is bolted to one side of the upper end of the music box base 1. The protective cover 3 is arranged on the outside of the driving rod 2 and the driving member 7. The protective cover 3 is made of a transparent resin material. By sleeved on the outside of the driving rod 2 and the driving member 7, it can prevent the hands of young children from accidentally entering the meshing part of the two and causing injuries. The transparent resin material makes the protective cover 3 have a high transparency, which is convenient for young children to see the driving principle clearly, and has a high teaching significance.
