[0002] Music is an art form and cultural activity, and its medium is regularly organized sound waves. In the process of music teaching, the music scores need to be explained so that students can master the relevant music theory knowledge in the music scores. When explaining the music scores, the music scores need to be placed, and a music notation board is usually used when placing the music scores.

[0003] The Chinese patent with the related patent publication number CN210727051U discloses a music score recognition board. The application states: "When using the existing music score recognition board, the height adjustment effect of the score recognition board is poor and it is not convenient to move, which affects students' viewing and learning of the music score recognition board and has a poor use effect." Although the application solves this problem, it has the following defects:

[0004] The music score recognition board in the above-mentioned prior art can only be adjusted in a small range when adjusting the height, resulting in that it cannot meet the needs of users of different heights when in use. Moreover, it can only be adjusted in height, and it is easy to be affected by light in a complex environment, resulting in unclear reading of the music score content. In addition, the music score cannot be well fixed when it is placed, resulting in the phenomenon of page flipping when viewing the music score. For this reason, we propose a music score recognition board. Utility Model Content

[0024] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0025] Example:

[0026] like Figure 1-Figure 5 As shown, a music score recognition board includes a base 1, a vertical rod 2 is fixedly connected to the top of the base 1, an adjustment mechanism 3 is arranged on the outer side of the vertical rod 2, a music board 5 is fixedly connected to the right side of the adjustment mechanism 3, a lighting assembly is fixedly connected to the top of the music board 5, and a limiting assembly 4 is arranged on the rear side of the music board 5.

[0027] The adjustment mechanism 3 includes a sleeve 301, which is sleeved on the outside of the vertical rod 2. A cylinder 303 is fixedly connected to the right side of the sleeve 301, a round rod 307 is slidably connected to the inside of the cylinder 303, and convex strips 305 distributed in an annular shape with equal intervals are fixedly connected to the outside of the round rod 307. An annular groove 308 is opened on the inside of the cylinder 303, and a tension spring 309 is fixedly connected to the left side of the cylinder 303.

[0028] The working principle of the above technical solution is as follows:

[0029] By canceling the limit of the sleeve 301 by the limit bolt 302, the height of the music board 5 is adjusted. The music board 5 is pulled rightward by the pull ring 304. The music board 5 moves rightward and drives the round rod 307 to move rightward until the round rod 307 leaves the cylinder 303. At this time, the music board 5 can be rotated under the action of the connecting rod 306, so as to adjust the inclination angle of the music board 5. After the adjustment is completed, the tension is slowly canceled, and the round rod 307 is allowed to enter the cylinder 303 again under the action of the tension spring 309 to complete the adjustment of the inclination angle of the music board 5.

[0030] In another embodiment, if Figure 2 As shown, a screw hole 1 is opened on the left side of the sleeve 301, and the inner side of the screw hole 1 is threadedly connected with a limiting bolt 302, and the right end of the limiting bolt 302 passes through the screw hole 1 and extends into the interior of the sleeve 301.

[0031] The limiting bolt 302 can limit the sleeve 301 after the height is adjusted, so as to ensure the stability after the height is adjusted and facilitate the use of the music board 5.

[0032] In another embodiment, if Figure 4 As shown, the right end of the tension spring 309 is fixedly connected to the connecting rod 306, and the connecting rod 306 is movably connected to the left end of the round rod 307 through a bearing.

[0033] The tension spring 309 can be connected to the round rod 307 under the action of the connecting rod 306, and the round rod 307 can be rotated under the action of the bearing.

[0034] In another embodiment, if Figure 2 and Figure 4 As shown, a pull ring 304 is fixedly connected to the right side of the music board 5 , and the convex strip 305 is slidably connected to the inner side of the corresponding groove 308 .

[0035] The pull ring 304 can pull the music board 5 to move, and the convex strip 305 and the groove 308 can limit the rotation of the round rod 307 to ensure that the inclination angle of the music board 5 can be maintained after the inclination angle is adjusted.

[0036] In another embodiment, if Figure 3 and Figure 5 As shown, the limiting component 4 includes a T-shaped slot 402, which is opened on the rear side of the music board 5. A T-shaped block 405 is slidably connected to the inner side of the T-shaped slot 402, an L-shaped block 401 is fixedly connected to the rear side of the T-shaped block 405, and an arc rod 403 is arranged on the front side of the L-shaped block 401.

[0037] Under the action of the T-shaped slot 402 and the T-shaped block 405 , the L-shaped block 401 can be moved in the left and right directions, so as to limit the position of the music scores of different sizes. Under the action of the arc rod 403 , the music scores can be limited.

[0038] In another embodiment, if Figure 5 As shown, the arc rod 403 is movably connected to the front side of the L-shaped block 401 through a bearing, and the other end of the arc rod 403 is fixedly connected to the anti-slip pad 404.

[0039] The L-shaped rod can rotate under the action of the bearing, and the anti-skid pad 404 protects the music score and has an anti-skid effect.

[0040] In another embodiment, if Figure 5 As shown, a second screw hole is provided at the rear side of the L-shaped block 401 , and a fixing bolt 406 is threadedly connected to the inner side of the second screw hole. The front end of the fixing bolt 406 passes through the L-shaped block 401 .

[0041] The second screw hole facilitates the screwing of the fixing bolt 406 , and the fixing bolt 406 limits the position of the L-shaped block 401 .

[0042] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
