[0029] Reference Figure 1-6 This utility model provides an embodiment:

[0030] A safer turntable harmonizer includes a housing 1, a support device, and a damping tray 3. The housing 1 includes a lower housing 11, a side housing 12, an upper housing 13, a vertical plate 14, and a horizontal plate 15. The side housing 12 is fixedly connected to the outer edge of the upper surface of the lower housing 11, the vertical plate 14 is fixedly connected to the outer edge of the upper surface of the lower housing 11, and the horizontal plate 15 is fixedly connected to the top of the vertical plate 14.

[0031] The support device includes a motor bracket 21, a geared motor 22, and a damping disc bracket 23. The motor bracket 21 is fixedly installed in the middle of the upper surface of the lower housing 11. The motor bracket 21 has a groove inside, in which the geared motor 22 is fixedly placed. The damping disc bracket 23 is fixedly connected to the motor bracket 21. A gear that mates with a gear ring 31 is installed at the output end of the geared motor 22.

[0032] The damping tray 3 includes a toothed ring 31, an upper outer ring 321, an upper inner ring 322, a lower outer ring 331, and a lower inner ring 332. The lower inner ring 332 is fixedly connected to the damping disc frame 23. The upper outer ring 321, the toothed ring 31, and the lower outer ring 331 are fixedly connected. The upper outer ring 321 and the upper inner ring 322 are rotatable. The lower outer ring 331 and the lower inner ring 332 are rotatable. A turntable 4 is fixedly installed on the upper surface of the upper inner ring 322.

[0033] The horizontal plate 15 is also equipped with an NFC sensor 151 and a bearing seat 152. The NFC sensor 151 is fixedly installed on the lower surface of the horizontal plate 15, and the bearing seat 152 is fixedly installed on the lower surface of the horizontal plate 15 away from the vertical plate 14. The bearing seat 152 is connected to the upper surface of the turntable 4, and an identification button 41 is detachably installed on the upper surface of the turntable 4. The outer surface of the identification button 41 is set with different colors, and different RFID electronic tags of different colors are fixedly installed inside the identification button 41. The NFC sensor 151 identifies the RFID electronic tag of the identification button 41.

[0034] A main board 121 is fixedly mounted on the inner surface of the side housing 12, and a tactile switch 122 and a single-turn rheostat 123 are mounted on the side wall of the side housing 12.

[0035] A speaker 141, a DC power supply 143, and a power switch 144 are fixedly installed on the side wall of the upright plate 14. An infrared sensor 142 is also fixedly installed on the side wall of the upright plate 14.

[0036] Working principle: When using this device, the reduction motor 22 is turned on. The output end of the reduction motor 22 is equipped with a gear that meshes with the gear ring 31. The reduction motor 22 rotates, which in turn drives the gear ring 31 to rotate. Since the upper outer ring 321, the gear ring 31, and the lower outer ring 331 are fixedly connected, the upper outer ring 321 and the lower outer ring 331 rotate synchronously.

[0037] Under normal conditions, due to resistance, the outer ring 321 of the upper plate will drive the inner ring 322 of the upper plate to rotate. A turntable 4 is fixedly installed on the upper surface of the inner ring 322 of the upper plate. At this time, the turntable 4 rotates.

[0038] When the child holds the turntable 4 still, since the outer ring 321 and the inner ring 322 of the upper plate can rotate, when the resistance generated by pressing is greater than the resistance between the outer ring 321 and the inner ring 322 of the upper plate, the turntable 4 will not move, and the outer ring 321 of the upper plate will rotate independently.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
