Description

Technical Field

[0001] This utility model relates to the field of English phonetics teaching technology, specifically a phonetics symbol hanging board for teaching. Background Technology

[0002] In English teaching, the recognition of phonetics and the English alphabet by beginners is extremely important. Phonetics are symbols used to record phonemes; they are the written representations of phonemes. The principle behind their creation is that one phoneme is represented by only one phonetic symbol, and one phonetic symbol represents only one phoneme. English is a phonetic language, and letters express sounds. However, English has more than 40 sounds but only 26 letters. To accurately represent pronunciation, phonetic symbols were introduced. These phonetic symbols are called phonetics. The International Phonetic Alphabet (IPA) is divided into two types: British IPA and American IPA. Learning English phonetics is a fundamental aspect of English language teaching.

[0003] Existing teaching phonetic symbol hanging boards are typically fixed to the wall using ropes, screws, or suction cups. However, these boards are limited in their use, as they are suspended from the wall and cannot be used vertically on the ground. Consequently, during teaching, the wall where the board is hung is often far from the students' desks, and the fixed position of the board affects students' learning outcomes, thus reducing the practicality of the teaching phonetic symbol hanging boards.

[0034] like Figure 2 , Figure 3 , Figure 4 and Figure 5 The support rod 401 has guide grooves 4011 on both sides. The support rod 401 has a positioning hole 4012 and a positioning hole 4013 on the side adjacent to the connecting block 405. The inner diameter of the positioning hole 4012 is the same as that of the positioning hole 4013. The inner diameter of the positioning hole 4012 is the same as that of the positioning block 406. The positioning block 406 can be matched with the positioning hole 4012 and the positioning hole 4013 respectively. When the positioning block 406 is matched with the positioning hole 4012, the support foot 404 is parallel to the support rod 401. When the positioning block 406 is matched with the positioning hole 4013, the support foot 404 is perpendicular to the support rod 401.

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 5The connecting block 405 is U-shaped, and the distance between the connecting block 405 and the positioning block 406 is the same as the axial dimension of the sleeve block 402. Both sides of the connecting block 405 can fit against the sleeve block 402. The connecting block 405 can move along the sleeve block 402, causing the positioning block 406 to move away from the sleeve block 402. Simultaneously, the sleeve block 402 causes the spring 407 to stretch, and the positioning block 406 moves along the guide hole 4021, separating from the first positioning hole 4012. When the sleeve block 402 moves the positioning block 406 to the position of the second positioning hole 4013, the connecting block 405 is released, and the spring... The elastic force of spring 407 causes the positioning block 406 to match the positioning hole 4013, making the multiple support feet 404 perpendicular to the support rod 401. A guide hole 4021 is provided on the side of the sleeve block 402 adjacent to the connecting block 405. The inner diameter of the guide hole 4021 is the same as the outer diameter of the positioning block 406. The guide hole 4021 can match the positioning block 406. A guide block 4022 is provided on the side of the sleeve block 402 adjacent to the guide groove 4011. The shape of the guide block 4022 is the same as the shape of the guide groove 4011. The guide block 4022 can match the guide groove 4011.

[0036] Specifically, manually rotating the connecting screw 2 separates it from the connecting hole 3011 at the current position, causing the telescopic component 3 to slide out of the storage cavity 101 under the influence of gravity. After the sleeve rod 301 slides out to the corresponding length, rotating the connecting screw 2 in the opposite direction makes it match the corresponding connecting hole 3011, separating the magnetic card block 303 from the connecting groove 3015. Then, pulling the slide rod 302 out to the corresponding distance makes the round block 3031 match the corresponding insertion hole 3022. By adjusting the extension length of the slide rod 302, the connecting block 405 can move along the sleeve block 402, driving the positioning block 406 to move away from the sleeve block 402. The positioning block 406 moves along the guide hole 40 21. The moving sleeve block 402 moves away from the sleeve rod 301 and separates from the positioning hole 4012. The sleeve block 402 can drive multiple connecting rods 403 to rotate. The connecting rods 403 on both sides drive the support feet 404 to rotate along the support rod 401. When the sleeve block 402 drives the positioning block 406 to the position of the positioning hole 4013, the connecting block 405 is released. The elastic force of the spring 407 makes the positioning block 406 match the positioning hole 4013, so that the multiple support feet 404 are perpendicular to the support rod 401. Similarly, the support components 3 and 4 on the other side are adjusted to the same position. The hanging plate 1 is erected on the ground for use through the support component 4. The height of the hanging plate 1 is adjusted through the telescopic component 3.
