Description

Technical Field

[0001] This utility model relates to the field of Chinese character learning technology, specifically to a rotary tube-type structure for combining initials and finals in Chinese character learning. Background Technology

[0002] A rotating cylinder-type Chinese character learning tool is a learning aid designed to help learners master the rules of combining initials and finals in Chinese characters. Its core purpose is to improve learners' ability to recognize and write Chinese characters. This tool typically consists of multiple rotating cylinders, each marked with a different initial or final.

[0021] Specifically, during operation, writing Chinese characters on the touchscreen sensor 120 sends a command, driving the motor 210 to rotate the reciprocating threaded rod 211, which in turn moves the one-way shaft 213, causing the spur gear 217 to move to the position of the nasal vowel fixing unit 430 and engage with the gear ring 432. The motor 210 then reverses the drive, rotating the spur gear 217 and causing the gear ring 432 to rotate to the designated position. At this point, the corresponding electromagnetic ring 114 is activated to attract one of the iron plates 435. The magnetic attraction causes the spring telescopic rod 434 to extend until the engraving plate 436 engages with the square groove 113. The drive motor 210 drives the reciprocating threaded rod 211 to rotate, which in turn moves the one-way shaft 213, causing the spur gear 217 to move to the position of the compound vowel fixing unit 420 and engage with the gear ring 422. The motor 210 then drives the spur gear 217 to rotate in the reverse direction, causing the gear ring 422 to rotate to the designated position. At this point, the corresponding electromagnetic ring 114 is activated to attract one of the iron plates 425. The magnetic attraction causes the spring telescopic rod 424 to stretch until the engraving plate 426 engages with the square groove 113. The drive motor 210 continues to drive the one-way shaft 213 to move, which in turn moves the spur gear 217. The device moves to the position of the single vowel fixing unit 410 and engages with the gear ring 2 412. The motor 210 drives the spur gear 217 to rotate in the reverse direction. After the gear ring 2 412 rotates to the designated position, the corresponding electromagnetic ring 114 is activated to attract one of the iron plates 2 415. The magnetic attraction pulls the spring telescopic rod 2 414 until it engages with the engraving plate 2 416 and the square groove 113. This causes the spur gear 217 to continue moving to the position of the initial consonant combination mechanism 300 and engage with the gear ring 1 312. The motor 210 drives the spur gear 217 to rotate in the reverse direction, causing the gear ring 1 312 to rotate to the designated position. After placement, the corresponding electromagnetic ring 114 activates to attract one of the iron plates 314. The magnetic attraction pulls the spring telescopic rod 313 until the engraving plate 315 engages with the square groove 113. When learning is no longer needed, the electromagnetic ring 114 releases its attraction to the iron plates 314, 415, 425, and 435. The toothed rings 312, 412, 422, and 432 return to their original positions due to the springs 311, 413, 423, and 433, making them convenient for the next use and preventing the mispronunciation of initials and finals. Example 1

A spur gear 217 is fixedly connected between the outer walls of one end of the two square rods 215. The spur gear 217 is rotatably connected to the outer wall of the round rod 212. The consonant assembly mechanism 300 includes a ring frame 310. One end of the outer wall of the ring frame 310 is fixedly connected to the inner wall of the cylinder 111. The other end of the outer wall of the ring frame 310 is rotatably connected to the gear ring 312. The vowel combination mechanism 400 includes a single vowel fixing unit 410, a compound vowel fixing unit 420 and a nasal vowel fixing unit 430. The single vowel fixing unit 410 includes a rotating seat 411, the compound vowel fixing unit 420 includes a rotating seat 421, and the nasal vowel fixing unit 430 includes a rotating seat 431. The outer walls of the rotating seats 411, 421 and 431 are fixedly connected to the inner wall of the cylinder 111.

The spur gear 217 meshes with the gear ring 312 for transmission.

[0023] In this embodiment, the drive motor 210 drives the reciprocating threaded rod 211 to rotate, which in turn drives the one-way shaft 213 to move. This drives the spur gear 217 to move to the position of the nasal vowel fixing unit 430, the compound vowel fixing unit 420, the simple vowel fixing unit 410, or the initial consonant combination mechanism 300, where it engages with the gear ring 432, the gear ring 322, the gear ring 212, or the gear ring 1 312. The motor 210 drives the spur gear 217 to rotate in the reverse direction, which in turn drives the gear ring 432, the gear ring 322, the gear ring 212, or the gear ring 1 312 to rotate to the designated position.

[0024] like Figure 1-6As shown, in this embodiment, twenty-three spring telescopic rods 313 are fixedly connected at equal angles around the outer wall of gear ring 312, ten spring telescopic rods 414 are fixedly connected at equal angles around the outer wall of gear ring 412, fourteen spring telescopic rods 424 are fixedly connected at equal angles around the outer wall of gear ring 422, and sixteen spring telescopic rods 434 are fixedly connected at equal angles around the outer wall of gear ring 432.

[0025] In practice, after the gear rings 432, 422, 412 or 312 rotate to the designated position, the electromagnetic ring 114 is activated to attract the corresponding iron plates 435, 425, 415 or 314 respectively. The magnetic attraction pulls the spring telescopic rods 434, 424, 414 or 313 until they engage with the engraving plates 436, 426, 416 or 315 and the square groove 113. Example 2

[0026] Based on Embodiment 1, in order to compensate for the fact that after completing the spelling of the initial consonant and final vowel of a character in Embodiment 1, if the initial consonant combination mechanism 300 and the final vowel combination mechanism 400 have not returned to their correct initial positions, then when attempting to spell the next character, misjudgment may occur, resulting in spelling errors.

[0028] In practical implementation, when learning is not required, the electromagnetic ring 114 cancels its attraction to iron plates 314, 415, 425, and 435. The toothed rings 312, 412, 422, and 432 return to their original positions due to the springs 311, 413, 423, and 433, making them convenient for the next use and preventing the mispronunciation of initials and finals.
