[0024] By setting the positioning structure 4, the electric slide rail 401 and the electric slider 402 can drive the electric push rod 408 inside the embedded rod 404 to move horizontally, and then cooperate with the movable end of the electric push rod 408 to drive the pressing contact 409 to gradually contact the opened page of the music score body 3, which can realize the stable clamping of the music score, avoid the falling back of the opened page, especially in the outdoor performance environment, it can avoid the situation that the music score turns over automatically due to the wind, thus ensuring the normal performance of the performer.

[0025] Specifically, a splicing rod 104 is fixedly installed inside the connecting side rod 103, and the opposite ends of the two splicing rods 104 are fixedly connected to the side end of the support rod 105.

[0026] In this implementation scheme, through the mutual cooperation of the splicing rod 104 and the support rod 105, the connection stability between the connecting side rod 103 and the support rod 105 is increased, and the overall stability of the placement structure 1 is improved.

[0027] Specifically, a damping rotating rod 106 is provided at the top of the support rod 105, and the movable end of the damping rotating rod 106 is connected to the back side of the placement frame 107.

[0028] In this implementation scheme, the setting of the damping rotating rod 106 facilitates the adjustment of the angle of the placement frame 107 to meet the usage requirements of different performers. At the same time, the damping rotating rod 106 also has a certain resistance, which can maintain the stability of the placement frame 107 after adjustment.

[0029] Specifically, a reinforcing rod 108 is fixedly installed inside the placement frame 107, and a holding handle 109 is installed on the outer rod of the placement frame 107.

[0030] In this implementation scheme, the setting of the reinforcing rod 108 further improves the structural strength of the placement frame 107 and increases its load-bearing capacity; the setting of the holding handle 109 facilitates the performer to carry and move the entire automatic music score page-turning device for piano performance, improving the convenience of use.

[0031] Specifically, a telescopic hose 207 is fixedly installed at the intake end of the air suction pump 206, and the other end of the telescopic hose 207 is fixedly connected to the outlet end of the adsorption tube 205.

[0032] In this implementation scheme, the setting of the telescopic hose 207 increases the flexibility of the connection between the air suction pump 206 and the adsorption tube 205, so that the adsorption tube 205 will not be overly restricted when moving. At the same time, the telescopic hose 207 also has a certain elasticity, which can buffer the vibration generated when the adsorption tube 205 moves, ensuring the stability of the contact between the adsorption tube 205 and the opened page of the music score body 3.

[0033] Specifically, a dust-proof nozzle 208 is movably clamped at the air inlet end of the adsorption tube 205, and a filter screen is arranged inside the dust-proof nozzle 208.

[0034] In this implementation scheme, the filter screen arranged inside the dust-proof nozzle 208 can block external dust and impurities from entering the internal part of the suction pump 206, ensuring the normal operation of the suction pump 206 and extending its service life.

[0035] Specifically, an outer sleeve rod 405 is rotatably connected to the outside of the hinge shaft 403. The outer sleeve rod 405 is located outside the inner sleeve rod 404. A locking block 406 is installed inside the outer sleeve rod 405. When the outer sleeve rod 405 and the inner sleeve rod 404 are perpendicular to each other, the locking block 406 abuts against the outside of the inner sleeve rod 404.

[0036] In this implementation scheme, the outer sleeve rod 405 and the inner sleeve rod 404 cooperate with each other to enable flexible adjustment of the positioning structure 4, meeting the positioning requirements of different opened pages of the music score body 3.

[0037] The setting of the locking block 406 can lock the outer sleeve rod 405 when the outer sleeve rod 405 and the inner sleeve rod 404 are perpendicular to each other, preventing it from accidentally rotating and ensuring the stability of the positioning structure 4.

[0038] Specifically, a pressing contact 409 is arranged at the movable end of the electric push rod 408, and the pressing contact 409 is a soft rubber silicone grease post.

[0040] When in use, first spread out the music score body 3 and place it on the placing plate 110, then start the electric slide rail 401 and the electric slider 402, so that the electric slide rail 401 and the electric slider 402 can drive the inner sleeve rod 404 to perform adaptive adjustment according to the size of the music score, and further move the electric push rod 408 to the position of the opened page of the music score body 3; Next, the electric push rod 408 extends, and the pressing contact 409 at its movable end gently touches the opened page to achieve stable clamping of the music score; When it is necessary to release the positioning of the music score by the electric push rod 408, manually dial the outer sleeve rod 405 to separate the outer sleeve rod 405 from the electric push rod 408, so that the inner sleeve rod 404 can rotate freely at this time, and further cause the electric push rod 408 to be unable to press down on the music score. At this time, the music score body 3 can be easily taken off.

[0041] When it is necessary to turn the page of the sheet music, the electric push rod 408 is started in advance to cause the movable end of the electric push rod 408 to retract, releasing the clamping of the opened page of the sheet music body 3, so that the opened page of the sheet music body 3 can be turned without being pressed at this time; Subsequently, the servo motor 204 is started to drive the suction tube 205 to gradually approach and contact the edge of the currently opened page; At the same time, the air suction pump 206 starts to work, adsorbing the opened page through the suction tube 205 to form a separation gap with other sheets; Immediately afterwards, the drive motor 202 starts to operate, and its output shaft drives the rotating shaft 203 to gradually insert into the separation gap. This process is accompanied by the action of the adsorbed paper turning forward; As one page of paper is turned over, the electric push rod 408 adjusts its position again to clamp the new opened page, and the rotating shaft 203 and the suction tube 205 return to their initial positions, thus preparing for the next page-turning action.

[0042] The whole process does not require the performer to operate manually, realizing automatic page turning, which greatly improves the coherence and efficiency of the performance.

[0043] In summary, for the automatic sheet music page-turning device for piano performance, by setting the page-turning structure 2, the servo motor 204 can drive the suction tube 205 to gradually contact the opened page of the sheet music body 3, and then cooperating with the air suction pump 206, the opened page of the sheet music body 3 can be adsorbed through the suction tube 205, causing the paper to separate from other papers of the sheet music to form a separation gap. At the same time, the drive motor 202 can drive the rotating shaft 203 to gradually insert into the separation gap to push the adsorbed paper for page-turning processing, realizing automatic page turning of the sheet music when the performer plays the piano piece, enabling the performer to continuously play the piano piece, avoiding distraction caused by turning the music score, and thus improving the performance effect; By setting the positioning structure 4, the electric slide rail 401 and the electric slider 402 can drive the electric push rod 408 inside the embedded rod 404 to move horizontally, and then cooperating with the movable end of the electric push rod 408, the pressing contact 409 can be driven to gradually contact the opened page of the sheet music body 3, which can realize stable clamping of the sheet music, avoid the falling back of the opened page, especially in an outdoor performance environment, it can avoid the situation of the sheet music turning itself due to the wind, and thus ensure the normal performance of the performer.
