[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1-5The sheet music stand shown is suitable for teaching folk music, including a support column 1 for supporting the sheet music stand suitable for teaching folk music.

[0028] Support mechanism 2 is set outside the support column 1 and is used to house the support. The support column 1 has external threads. Support mechanism 2 includes threaded sleeve 201 and support rod 203. Telescopic column 3 is movably sleeved inside the support column 1.

[0029] An angle adjustment mechanism 5 is installed on the upper end of the telescopic column 3 for angle adjustment. The angle adjustment mechanism 5 includes a fixed frame 501, which is fixedly connected to the upper end of the telescopic column 3. A movable plate 503 is movably sleeved inside the fixed frame 501. A swing frame body 504 is hinged to the front side of the movable plate 503. A connecting rod 505 is hinged to the rear end of the movable plate 503. A limit frame 506 is fixedly connected to one end of the connecting rod 505. An adjustment frame 507 is fixedly connected to the rear side of the swing frame body 504. Limit grooves 508 are opened on the inner surface of the adjustment frame 507.

[0030] The limiting clamping mechanism 6 is rotatably connected to both sides of the surface of the swing frame body 504 and is used to clamp the sheet music. By rotating and adjusting the swing frame body 504 on the fixed frame 501, when the appropriate angle is reached, the connecting rod 505 on the rear side of the fixed frame 501 and the limiting frame 506 are placed in the limiting groove 508 inside the adjusting frame 507 on the rear side of the swing frame body 504 to complete the angle adjustment and limiting of the swing frame body 504. Compared with the traditional bolt tightening method, this is simple to operate and less prone to tilting, with good stability and greater durability; it is especially suitable for beginners, especially students in the teaching process who use it for the first time and in the early stages.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the threaded sleeve 201 is threadedly connected to the outside of the support column 1. A support frame 202 is fitted around the outside of the threaded sleeve 201. The support rod 203 is hinged around the support frame 202. A movable rod 204 is hinged inside the support rod 203. By rotating the threaded sleeve 201 outside the support column 1, the threaded sleeve 201 can move up and down through the threads on the outside of the support column 1. During the extension and retraction of the threaded sleeve 201, the externally fitted support frame 202 and the surrounding support rods 203 and movable rods 204 are retracted, thus facilitating the storage of the entire support mechanism 2 and providing support for the entire music score display stand.

[0032] like Figure 2As shown, the threaded rotating sleeve 201 is rotatably connected to the support frame 202, and the other end of the movable rod 204 is hinged to the outside of the support column 1. By rotating the threaded rotating sleeve 201, it moves on the external thread of the support column 1. The threaded rotating sleeve 201 is rotatably connected to the support frame 202, so that the threaded rotating sleeve 201 moves outside the support column 1 and simultaneously drives the support frame 202 to move and extend, thereby facilitating the storage and support of the support rod 203.

[0033] like Figure 1 and Figure 3 As shown, the external thread of the support column 1 passes through the first tightening member 4. The support column 1 and the telescopic column 3 are slidably connected. The telescopic column 3 can extend and retract inside the support column 1. When the extension and retraction are adjusted to the required height, the first tightening member 4 on the outside of the support column 1 is turned to limit and lock the telescopic column 3 inside the support column 1.

[0034] like Figure 1 and Figure 4 As shown, the upper end of the fixed frame 501 is threaded with a second tightening member 502, the movable plate 503 is slidably connected to the fixed frame 501, the limiting frame 506 is movably engaged with the adjusting frame 507, the movable plate 503 can move back and forth within the fixed frame 501 for adjustment, and when adjusted to a suitable length, the second tightening member 502 is tightened to limit and lock the movable plate 503 within the fixed frame 501.

[0035] like Figure 1 and Figure 5 As shown, the limiting clamping mechanism 6 includes a movable shaft 601, which is rotatably connected to both sides of the front of the swing frame body 504. A movable plate 602 is fixedly connected to the outside of the movable shaft 601. A telescopic rod 603 is movably sleeved inside the other end of the movable plate 602. A top block 604 is fixedly connected to the outside of the telescopic rod 603. A spring 605 is provided on the rear side of the top block 604. A pressure block 606 is fixedly connected to the front end of the telescopic rod 603. When the sheet music is placed on the swing frame body 504, the pressure block 606 and the compression spring 605 are driven by pulling the telescopic rod 603. Then, the telescopic rod 603 and the movable plate 602 are rotated, and the movable shaft 601 rotates on the swing frame body 504. When the pressure block 606 is in front of the sheet music, the telescopic rod 603 is released and the external spring 605 rebounds, pressing the pressure block 606 onto the surface of the sheet music to clamp and limit its position.

[0036] The working principle of this practical application is as follows: First, place the entire music score holder in the desired position. Then, rotate the threaded sleeve 201 on the outside of the support column 1. The threaded sleeve 201 can move up and down through the threads on the outside of the support column 1. During the extension and retraction of the threaded sleeve 201, the externally mounted support frame 202 and the surrounding support rods 203 and movable rods 204 retract and expand, thus facilitating the support of the entire support mechanism 2. Then, according to the user's height, pull the telescopic column 3 out of the support column 1. After adjusting the extension and retraction to the desired height, tighten the first fastener 4 on the outside of the support column 1 to lock the telescopic column 3 within the support column 1. According to the angle observed by the user for the placement of the main body 504 of the stand, rotate and adjust the main body 504 on the fixed frame 501 until a suitable angle is reached. Then, place the connecting rod 505 and the limiting frame 506 on the rear side of the fixing frame 501 into the limiting groove 508 inside the adjusting frame 507 on the rear side of the main body of the swing frame 504 to complete the angle adjustment and limiting of the main body of the swing frame 504. Compared with the traditional bolt tightening method, it is more secure and durable. Then, place the sheet music in front of the main body of the swing frame 504. Pull the telescopic rod 603 to drive the pressure block 606 and the compression spring 605. Then rotate the telescopic rod 603 and the movable plate 602. Use the movable shaft 601 to rotate on the main body of the swing frame 504. When the pressure block 606 is in front of the sheet music, release the telescopic rod 603 and use the external spring 605 to rebound, pressing the pressure block 606 onto the surface of the sheet music to clamp and limit it. In this way, the use process of the sheet music swing frame suitable for ethnic music teaching is completed.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
