[0002] A music score support stand is a tool used to support music scores. It is mainly used to facilitate performers (such as pianists, violinists, etc.) to clearly see the music scores during the performance. It can also provide support for the music scores for teachers during the teaching process, while freeing their hands, making performance or teaching smoother and more convenient.

[0003] The existing utility model with authorization announcement number CN214152430U discloses a music score swing stand for piano teaching. By setting a swing frame body and a fixed horizontal axis provided under the swing frame body, the teacher can flip the music score at a regular time when teaching piano and using the adjustment part provided under the swing frame body for piano teaching. The rotating part provided under the swing frame body can be rotated, thereby effectively flipping the music score automatically and preventing the swing frame body from slipping. The fixing part provided under the swing frame body further improves the stability of the swing frame body and further improves the teaching efficiency of the teacher.

[0004] Although the above technical solution can automatically turn the music scores at a fixed time, the support surface for the scores is relatively limited, and there is a lack of a large support surface structure that is convenient for folding. As a result, the number of scores that can be displayed simultaneously during music teaching is relatively limited, and the space occupied when stored is relatively large.

[0005] Therefore, those skilled in the art provide an adjustable music score support stand for music teaching to solve the problems raised in the above background technology. Utility Model Content

[0023] See also Figure 1-5A music sheet support frame for music teaching includes a support plate 1, a large support surface folding mechanism 2 is provided above the support plate 1, the large support surface folding mechanism 2 includes two storage shells 201, each storage shell 201 is slidably connected to an expansion plate 202, the outer surface of the support plate 1 is slidably connected to a support shell 3, and the bottom surface of the support shell 3 is fixedly connected to a counterweight base 4. By providing the support shell 3, the support plate 1 can slide up and down relative to it, thereby facilitating the adjustment of the height of the entire music sheet support frame in conjunction with other limiting structures. By providing the counterweight base 4, the supporting area of ​​the support shell 3 can be increased, thereby increasing the stability of the entire music sheet support frame when placed.

[0024] The upper surface of the support plate 1 is fixedly connected to a support base 203, and the upper surface of the support base 203 is fixedly connected to two vertical rods 204. The bottom surface of each storage shell 201 is in contact with the upper surface of the support base 203, and the outer surface of each vertical rod 204 is rotatably connected to the inner wall of the storage shell 201. The outer surface of the support shell 3 is fixedly connected to an anti-slip cover 5, and the outer surface of the anti-slip cover 5 is fixedly connected to a number of identical anti-slip bosses 6. By providing the anti-slip bosses 6, the anti-slip property of the outer surface of the anti-slip cover 5 can be increased. By providing the anti-slip cover 5 and the anti-slip bosses 6, the anti-slip property of the outer surface of the support shell 3 can be jointly increased, thereby making it convenient to hold the support shell 3 by hand and carry and move the entire music score support stand.

[0025] The front of each storage shell 201 is fixedly connected to a fixed support plate 205, the inner wall of each expansion plate 202 is fixedly connected to a transverse rod 206, and the inner wall of the support shell 3 is threadedly connected to a first hand-tightened threaded push rod 7, and the end of the first hand-tightened threaded push rod 7 close to the support plate 1 is in contact with the front of the support plate 1. By setting the first hand-tightened threaded push rod 7, it can move relative to the inner wall thread of the support shell 3 after being twisted by hand, thereby facilitating the tightening of the support plate 1 to fix the height of the support plate 1 in the support shell 3.

[0026] The outer surface of each transverse rod 206 is rotatably connected to a movable support plate 207, and the outer surface of each movable support plate 207 is in contact with the inner wall of the expansion plate 202. The inner wall of each storage shell 201 is threadedly connected to a second hand-tightened threaded top rod 8, and the bottom end of each second hand-tightened threaded top rod 8 is in contact with the upper surface of the expansion plate 202. By setting the second hand-tightened threaded top rod 8, the expansion plate 202 can be tightened after being twisted by hand, thereby facilitating the fixing of the expansion plate 202 in the internal position of the storage shell 201 and preventing the expansion plate 202 from sliding out of the storage shell 201 at will.

[0027] The side surfaces of the two expansion plates 202 that are away from each other are fixedly connected to the limiting plates 208, and the outer surface of each vertical rod 204 is threadedly connected to a hand-tightening nut top block 9, and the bottom surface of each hand-tightening nut top block 9 is in contact with the upper surface of the storage shell 201. By setting the hand-tightening nut top block 9, it can move up and down along the outer surface thread of the vertical rod 204 after being twisted by hand, and then it is convenient to cooperate with the support seat 203 to clamp the storage shell 201, thereby preventing the storage shell 201 from rotating freely along the outer surface of the vertical rod 204.

[0028] The working principle of the present invention is as follows: when in use, the entire sheet music support frame can be folded and stored in a small volume and unfolded with a large support surface. When the height of the entire sheet music support frame needs to be adjusted, the support plate 1 is slid up and down inside the support shell 3, and then the first hand-tightened threaded push rod 7 is screwed along the inner wall thread of the support shell 3 to tighten the front of the support plate 1 and fix the position of the support plate 1 inside the support shell 3. When multiple sheet music need to be supported, the two storage shells 201 are rotated around the outer surface of the vertical rod 204 so that the front surfaces of the two storage shells 201 are in the same plane, and then the hand-tightened nut push block 9 is screwed around the outer surface thread of the vertical rod 204 and then cooperates with the support seat 203 to clamp the storage shell 201, and then the expansion plate 202 is slid out of the storage shell 201 until the movable support plate 2 07 can be rotated around the horizontal rod 206 and then turned out from the inside of the expansion plate 202, and then the second hand-tightened threaded top rod 8 is screwed to make the second hand-tightened threaded top rod 8 press the upper surface of the expansion plate 202, and then the score can be stably placed under the back support of the storage shell 201 and the expansion plate 202 and the bottom support of the fixed support plate 205 and the movable support plate 207. When the entire music score support frame needs to be stored, the reverse operation can be performed with reference to the above-mentioned large-area expansion process, which increases the number of scores supported by the entire music score support and reduces the space occupied when stored. The design of the entire adjustable music score support frame for music teaching effectively solves the problem that the number of scores that can be displayed simultaneously during music teaching is relatively limited due to the lack of a large support surface structure that is convenient for folding, and the space occupied when stored is large.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
