[0020] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figure 1 and Figure 2 As shown, a self-turning music stand includes a frame body, and the frame body includes a music score placement plate 13, on which a music score 21 is placed, and the music score placement plate 13 is densely provided with through holes, and a page turning component is arranged in the through hole through a fixing component, and the page turning component is fixedly arranged on the fixing component and arranged at a suitable through hole position, and the page turning component is controlled and triggered by a control component.

[0022] like Figure 2 and Figure 3 As shown, the frame also includes a placement plate connector 23 fixedly connected to the music sheet placement plate 13, the placement plate connector 23 is fixedly connected to the upper end of the telescopic rod 10, and a bracket 12 is fixedly provided at the lower end of the telescopic rod 10; the telescopic rod 10 can adjust the placement height of the music sheet placement plate 13.

[0023] The page turning component includes a footer turning module, which includes a footer motor 17 fixedly arranged on the fixed component, a footer gear box 18 fixedly arranged on the output end of the footer motor 17, a footer roller 16 fixedly arranged on the output shaft of the footer gear box 18, and the footer roller 16 is set at the edge of the page of the music score 21; when it is necessary to turn the page, the footer motor 17 is triggered to rotate through the control module, and the footer motor 17 will drive the footer roller 16 to rotate through its output shaft after the footer gear box 18 changes direction, thereby driving the page on the side in contact with it to move inward and bend the middle.

[0024] The page turning assembly also includes a lever page turning module, which includes a lever motor 32 fixedly arranged on the fixed assembly, and a lever 19 is fixedly arranged on the lever motor 32, and the setting position of the lever 19 is located just above the middle of the music score 21; when the page footer turning module causes the page on one side to move inward and bend the middle part, the lever motor 32 drives the lever 19 to rotate one circle, so that the lever 19 extends from the bent and raised part of the middle part of the page to between the two pages, and as the lever 19 rotates, the page on the upper side will be pushed to the other side, thereby completing the basic page turning.

[0025] like Figure 2 and Figure 4As shown, the page turning assembly also includes a paperweight module, and the paperweight module includes a paperweight motor 33 fixedly arranged on the fixed assembly, and a paperweight gear box 34 is fixedly arranged on the output end of the paperweight motor 33, and a pressure rod 20 is fixedly arranged on the output shaft of the paperweight gear box 34, and the setting position of the pressure rod 20 is located on the opposite side of the footer turning module; when the lever page turning module completes the basic page turning and starts the paperweight motor 33, the paperweight motor 33 will drive the music score 21 to rotate to the upper side of the newly turned page after the paperweight gear box 34 changes direction, and then work in the reverse direction, so that the pressure rod 20 is pressed onto the music score 21, so as to prevent the music score 21 on this side from tilting up.

[0026] like Figure 6 As shown, the fixing assembly includes a mounting plate 24, on which a page turning assembly is directly fixed, and on which a local threaded shaft 31 is rotatably arranged, and the local threaded shaft 31 penetrates the mounting plate 24, and a knob 25 is fixedly arranged on the local threaded shaft 31 on the side away from the sheet music placement plate 13, and the sheet music placement plate 13 close to the sheet music placement plate 13 is threadedly connected with an upper support ring 27, a middle support ring 30, and a lower support ring 35 in sequence from front to back, and the lower support ring 35 is also fixedly connected to the mounting plate 24, and active support rods 28 are equidistantly arranged in an annular shape on the outer side of the upper support ring 27, and the other end of the active support rod 28 is rotatably arranged on the clamping rod 26, and the middle support ring 30, the lower support ring 35, the lower support ring 35, the lower support ring 35 is also fixedly connected to the mounting plate 24, and active support rods 28 are equidistantly arranged in an annular shape on the outer side of the upper support ring 27, and the other end of the active support rod 28 is rotatably arranged on the clamping rod 26, The outer side of the lower support ring 35 is equidistantly provided with driven support rods 29 parallel to each other, and the other end of the driven support rod 29 is rotatably connected to the clamping rod 26; when it is necessary to fix the page turning assembly in the through hole on the music score placement plate 13 through the fixing assembly, the local threaded shaft 31 is rotated by turning the knob 25. Since the lower support ring 35 is fixedly connected to the mounting plate 24, the clamping rod 26 cannot rotate with the rotation of the local threaded shaft 31 at this time, so that the upper support ring 27 moves toward the middle support ring 30 under threaded cooperation. During the movement, the upper support ring 27 will drive the clamping rod 26 to expand outward through the active support rod 28, so that the clamping rod 26 is clamped in the through hole of the music score placement plate 13.

[0027] like Figure 2 and Figure 5 As shown, the control component includes an ultrasonic sensor 14 fixedly mounted on the telescopic rod 10, and a controller 15 fixedly mounted on the sheet music placement board 13; the user triggers the ultrasonic sensor 14 through leg movements, so that the controller 15 controls the page turning component to complete a predetermined action.

[0028] The above-described embodiments are only descriptions of the preferred implementation methods of the utility model, and do not limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various modifications and improvements made by ordinary personnel in this field to the technical solution of the utility model should fall within the protection scope of the utility model, and the technical contents of the utility model for protection have been fully recorded in the claims.
