Description

TECHNICAL FIELD

[0001] The utility model relates to musical instrument technical field especially, a kind of Guqin string board with adjustable function. BACKGROUND

[0002] Guqin, also known as Yaoyin, Yujin and Qixianqin, is a traditional plucked string instrument in China. The tone of Guqin is closely related to the tightness of the fixed strings. The Guqin has a string board on the top and a goose foot at the waist. One end of the string is wound and fixed on the goose foot, and the other end is wound and fixed on the string eye of the string board.

[0003] Currently, when adjusting the string through the string board, only the string is pulled to one end for adjustment. During adjustment, the string is manually plucked to determine whether the tone is accurate. This adjustment method has large errors, and it is difficult to know whether the string reaches the maximum tension during adjustment, so the string is easily broken. UTILITY MODEL CONTENT

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Example 1, such as Figures 1-4 As shown, this utility model provides a technical solution for an adjustable guqin (a traditional Chinese stringed instrument) bow board: It includes a soundboard 1, a bow board 2 fixed to one side of the top of the soundboard 1, multiple end posts 4 equidistantly fixed to the other side of the top of the soundboard 1, multiple strings 3 arranged above the top of the soundboard 1, one end of each string 3 correspondingly wound and fixed to the end post 4, and the other end of each string 3 fixed to a string connector 8. The outer surface of each string connector 8 has an annular opening 18. Multiple string supports 5 equidistantly fixed to one side of the top of the bow board 2, one end of each string 3 engaging with the top of the string support 5. Multiple mounting grooves 6 are formed to the top of the bow board 2 near one side of the top, and adjusters are installed inside each mounting groove 6. Each adjuster includes a push block 7, which engages within the mounting groove 6. The push block 7 has a tapered traction groove 10 near one edge and a hexagonal groove 11 near the other edge. One side of the hexagonal groove 11 is connected to the inside of the tapered traction groove 10. A guide sleeve 9 is fixed to one side of the push block 7. One end of the guide sleeve 9 extends into the inside of the tapered traction groove 10. The chord end 8 is slidably inserted into the inside of the guide sleeve 9, and the annular opening 18 extends into the inside of the tapered traction groove 10. A hexagonal sliding plate 16 is slidably arranged between the inner walls of the hexagonal groove 11. Multiple spring clips 17 are equidistantly arranged along the circumferential direction on the inner wall of the tapered traction groove 10. The outer surfaces of the multiple spring clips 17 are all in contact with the inner wall of the tapered traction groove 10. One end of each of the multiple spring clips 17 extends into the inside of the hexagonal groove 11 and is fixed to one side of the hexagonal sliding plate 16.

[0023] The effect achieved by the entire embodiment 1 is that, in actual use, one end of the string 3 is provided with a string connector 8, and the string connector 8 is inserted into the conical pull groove 10. Thus, when the adjusting bolt 12 is rotated, the adjusting bolt 12 drives the hexagonal slide plate 16 to slide to the other side of the push block 7. When the hexagonal slide plate 16 slides, it will pull multiple spring clips 17 towards the hexagonal groove 11. During the pulling process, under the guidance of the conical surface of the conical pull groove 10, the hook part of one end of multiple spring clips 17 will shrink towards the middle and then lock into the annular opening 18. At the same time, the hexagonal slide plate 16 slides to the other side of the push block 7, so that it can pull the string connector 8, thereby achieving the purpose of pulling and adjusting the string 3.

[0024] Example 2, as Figures 1-4 As shown, an adjusting bolt 12 is provided on the other side of the push block 7. One end of the adjusting bolt 12 is threaded through the interior of the hexagonal groove 11 and rotatably connected to the other side of the hexagonal slide plate 16. A through-hole 13 is provided on the top surface of the interior of the hexagonal groove 11, extending through to the top of the push block 7. A scale strip 14 is fixed on the top of the push block 7, and a pointer 15 is fixed on the top of the hexagonal slide plate 16. The top of the pointer 15 extends above the push block 7 and extends above the scale strip 14.

[0025] The effect achieved by the entire embodiment 2 is that when the hexagonal slide plate 16 slides to the other side of the push block 7, it will drive the pointer 15 to slide. When the pointer 15 slides, the position corresponding to the top of the pointer and the scale on the scale bar 14 will change. People can observe the position of the pointer 15 and the scale on the scale bar 14 to obtain the pulling stroke of the string 3, thus avoiding breaking the string 3 after reaching the maximum pulling amount.

[0026] Working principle: One end of the string 3 is provided with a string connector 8, which is inserted into the conical pull groove 10. When the adjusting bolt 12 is rotated, the adjusting bolt 12 drives the hexagonal slide plate 16 to slide to the other side of the push block 7. When the hexagonal slide plate 16 slides, it pulls multiple spring clips 17 towards the hexagonal groove 11. During the pulling process, under the guidance of the conical surface of the conical pull groove 10, the hook part of one end of the multiple spring clips 17 retracts towards the middle and then engages in the annular opening 18. Simultaneously, the hexagonal slide plate 16 slides to the other side of the push block 7, allowing it to pull the string end 8, thereby achieving the purpose of pulling and adjusting the string 3. When the hexagonal slide plate 16 slides to the other side of the push block 7, it will cause the pointer 15 to slide. When the pointer 15 slides, the position corresponding to the scale on the scale bar 14 will change. People can observe the position of the pointer 15 and the scale on the scale bar 14 to obtain the pulling stroke of the string 3, thus avoiding breaking the string 3 after reaching the maximum pulling amount.
