[0033] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0034] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0035] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0036] See also Figures 1-14 In an embodiment of the present invention, a sheet music holder for triggering automatic page turning includes: A bottom support member 1 is mounted on a music board 5 for placing music scores. The music board 5 is provided with a page-starting assembly, a page-turning assembly, and a pressing assembly. The page-starting assembly includes a page-starting member rotatably mounted on the music board 5. The movement of the page-starting member can drive the paper to turn over. For details, please refer to Figure 1 The music board 5 is provided with a support plate 501. When the music sheet is placed on the music board 5, the center seam of the music sheet coincides with the symmetry axis in the length direction of the music board 5. The lower part of the music sheet is supported by the support plate 501. The support plate 501 can prevent the music sheet from sliding down, and at the same time provides a prerequisite for subsequent page turning operations. Preferably, as a further optimization of this solution, the above-mentioned music board 5 can be connected to the bottom supporting member 1 by adjusting the rotating member. When the user is playing, the angle between the music board 5 and the bottom supporting member 1 can be changed according to actual usage habits and needs by controlling the adjusting rotating member.

[0037] The page starter includes a deflection rod 7 rotatably mounted on the music board 5. The deflection rod 7 is symmetrically arranged in two groups along the width direction of the music board 5. A deflection plate 6 is rotatably mounted between the two groups of deflection rods 7. The deflection plate 6 is provided with an adhesive disc 601. In particular, see Figure 1 、 Figure 2 、 Figure 12 The deflection plate 6 is rotatably mounted on the two sets of deflection rods 7, and the plane formed by the deflection center of the deflection rod 7 and the symmetry axis in the longitudinal direction of the music board 5 remains perpendicular to the music board 5. When the deflection rod 7 drives the deflection plate 6 to deflect, the adhesive disc 601 provided on the deflection plate 6 is affected by gravity, so that the deflection plate 6 and the music board 5 are always kept parallel, thereby driving the paper to be turned over. The above-mentioned adhesive disc 601 has certain adhesive properties and elastic deformation capabilities, and can be disassembled and replaced. When not in use, a mounting cover is provided on the adhesive disc 601. The mounting cover can protect the adhesive disc 601 and prevent dust from adhering to the adhesive disc 601 and affecting the adhesion of the adhesive disc 601 to the paper.

[0038] The pressing assembly includes a movable frame 9 provided on the music board 5. The movable frame 9 is provided with a pressing structure. When the movable frame 9 slides relative to the music board 5, the pressing structure also moves accordingly, thereby pressing the music after turning the page. For details, please refer to Figure 1In the initial state, the pressing assembly and the page opening assembly are respectively arranged on the left and right sides of the music board 5, and can respectively press the left and right pages of the opened music score to prevent the left and right pages of the music score from being flipped or hinged due to the surrounding wind fluctuations during the performance, so that the performer can read the music score correctly and smoothly; For details, please refer to Figure 5 、 Figure 14 A clamping rod 902 is fixedly provided on the above-mentioned movable frame 9. The clamping rod 902 is slidably provided in the clamping groove 502 provided on the music board 5. Under the cooperation between the clamping rod 902 and the clamping groove 502, the movable frame 9 can only slide along the length direction of the music board 5, thereby driving the pressing structure to press the music score.

[0039] The pressing structure includes a threaded rod 21 and a guide rod 33 provided on the movable frame 9. A pressing plate 20 is provided between the threaded rod 21 and the guide rod 33. A threaded sleeve 22 is fixedly provided on the pressing plate 20. The threaded sleeve 22 is threadedly connected to the threaded rod 21. A ratchet 11 is coaxially fixedly provided on the threaded rod 21. The ratchet 11 cooperates with a ratchet plate 10 fixedly provided on the music board 5. For details, please refer to Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 13 、 Figure 14 The ratchet plate 10 is provided with a plurality of groups of ratchets equidistantly and rotatably mounted thereon. Each group of ratchets is connected to the ratchet plate 10 by a spring plate. With the cooperation of the spring plate, the ratchets are always in an open state. Therefore, when the movable frame 9 moves toward one side, the ratchets can cooperate with the pawls on the ratchet wheel 11, thereby driving the ratchet wheel 11 to rotate. As the ratchet wheel 11 rotates, the ratchet wheel 11 also rotates, thereby driving the pressing plate 20 to gradually move away from the music board 5 along the axial direction of the guide rod 33, thereby pressing the left side of the music score after the page is turned.

[0040] For further information, see Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 11 The music board 5 is further provided with a driving assembly, which includes a moving member slidably arranged on the music board 5, and the moving member is connected to a trigger assembly arranged on the bottom supporting member 1. When the trigger assembly is triggered, the page-starting member can first turn over the paper, and then the page-turning assembly can drive the turned paper to move toward the pressing structure. When the paper is about to be completely turned over, the pressing structure is actuated to press the turned music sheet. The driving assembly includes a first driving rod 12, a second driving rod 13, and a third driving rod 14 rotatably mounted on the music board 5. The first driving rod 12 is connected to the rotating shaft 701 of the deflection rod 7 via a bevel gear set. The first driving rod 12 is provided with a first rotation groove 1201 and a first sliding groove 1202. The second driving rod 13 is provided with a second sliding groove 1301 and a spiral groove 1302. The third driving rod 14 is provided with a third sliding groove 1401 and a third rotation groove 1402. The movable member includes three groups of movable sleeves 25 respectively sleeved on the first drive rod 12, the second drive rod 13 and the third drive rod 14. The three groups of movable sleeves 25 are fixedly connected to each other, and the inner wall of each group of movable sleeves 25 is fixedly provided with a ball, and the ball is slidably provided in a groove structure provided on the first drive rod 12, the second drive rod 13 and the third drive rod 14 respectively; Combine Figure 5 In the initial state, the movable sleeve 25 is close to the left side of the music board 5. From top to bottom, the balls on the inner wall of the movable sleeve 25 are respectively located at the end of the third sliding groove 1401, the second sliding groove 1301 and the first rotating groove 1201. When using the music sheet holder, first place the music sheet on the music sheet board 5, then remove the installation cover, and the adhesive disc 601 can adhere to the edge of the right paper. When it is necessary to turn the page of the music sheet, the trigger assembly can drive the movable sleeve 25 to move toward the right. During the movement, the balls on the inner wall of the movable sleeve 25 on the second driving rod 13 and the third driving rod 14 slide in the second sliding groove 1301 and the third sliding groove 1401 respectively. At this time, the second driving rod 13 and the third driving rod 14 remain stable. At the same time, the balls on the inner wall of the movable sleeve 25 on the first driving rod 12 contact and squeeze the first rotating groove 1201, which can force the sheet to turn. The first drive rod 12 rotates counterclockwise, and then, in conjunction with the bevel gear assembly, the first drive rod 12 drives the deflection rod 7 to rotate clockwise. At this time, the adhesive disk 601 can adhere to a piece of paper and drive the paper to flip toward the left. In particular, during the flipping process, because the flipping center of the music sheet is higher than the deflection center of the deflection rod 7, the paper will bend. This bending facilitates subsequent page turning by the page turning assembly. In addition, when the deflection rod 7 drives the deflection plate 6 and the adhesive disk 601 to flip, it can be ensured that each time a page is turned, only the paper in contact with the adhesive disk 601 is driven to start a page, thereby avoiding excessive page turning. When the ball on the inner wall of the movable sleeve 25 on the first driving rod 12 is separated from the first rotating groove 1201, the deflection angle of the deflection rod 7 reaches the maximum. Then, with the continued movement of the movable sleeve 25, the ball on the inner wall of the movable sleeve 25 on the first driving rod 12 is combined with the first sliding groove 1202, and the position of the first driving rod 12 remains stable. At the same time, the ball on the inner wall of the movable sleeve 25 on the second driving rod 13 contacts the spiral groove 1302. With the continued movement of the movable sleeve 25, the ball can drive the second driving rod 13 to rotate counterclockwise. Then, the rotating second driving rod 13 can drive the page turning component to move, thereby turning the paper adhered to the adhesion plate 601.

[0041] For details, please refer to Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 The page turning assembly includes a movable structure and a telescopic structure. The movable structure includes a pulley 18 rotatably mounted on the music board 5. The pulleys 18 are provided in two groups, one of which is connected to the second drive rod 13 via a bevel gear set. A belt 19 is provided between the two groups of pulleys 18. A mounting plate 1901 is fixedly provided on one of the running ends of the belt 19. Combined with the above, refer to Figure 5 In this example, when second drive rod 13 rotates counterclockwise, driven by the bevel gear train, it drives pulley 18 clockwise. Belt 19, driven clockwise by pulley 18, then moves mounting plate 1901 to the right. During this process, the telescopic mechanism is triggered, inserting itself between the flipped sheet and the remaining paper on the right. As mounting plate 1901 moves, the telescopic mechanism drives the flipped sheet to continue flipping to the left, thereby turning the pages of the sheet music.

[0042] Specifically, the telescopic structure includes an L-shaped plate 8 fixedly arranged on the mounting plate 1901, a telescopic plate 23 is slidably arranged on the L-shaped plate 8, and a deflection sleeve 24 is rotatably mounted on the L-shaped plate 8, a second plug rod 34 is rotatably mounted on the telescopic plate 23, an end of the second plug rod 34 away from the telescopic plate 23 is inserted in the deflection sleeve 24, and an end of the deflection sleeve 24 away from the second plug rod 34 is inserted with a first plug rod 30, the first plug rod 30 is rotatably connected to a moving rod 27 slidably arranged on the mounting plate 1901, the moving rod 27 is provided with a fixing rod 28 and a protruding column 2701, a fixing piece 1902 fixed to the mounting plate 1901 is slidably provided on the fixing rod 28, and a second spring 29 is further provided on the fixing rod 28, one end of the second spring 29 abuts against the end of the fixing rod 28, and the other end abuts against the fixing piece 1902; Specifically, a limit block 2702 is fixedly provided on one side of the movable rod 27 facing the mounting plate 1901. The limit block 2702 is slidably disposed within a movable groove 1903 provided on the mounting plate 1901. The limit block 2702 and the movable groove 1903 cooperate to allow the movable rod 27 to slide only along the width direction of the music board 5. In particular, the second spring 29 is always in a compressed state. The second spring 29 in the compressed state pushes the moving rod 27 to move toward the belt 19, and a T-block 1904 is fixedly provided on the side of the mounting plate 1901 facing the music board 5. The T-block 1904 is slidably set in the T-slot 503 opened on the music board 5. Under the cooperation of the T-block 1904 and the T-slot 503, the mounting plate 1901 can only drive the moving rod 27 to slide along the length direction of the music board 5, thereby turning the turned-up paper.

[0043] Furthermore, the protrusion 2701 cooperates with a guide structure provided on the music board 5. The guide structure includes a trigger block 17 fixedly provided on the music board 5. The trigger block 17 is provided with a vertical groove 1701, a horizontal groove 1702, an oblique groove 1703, and a reset groove 1704. The vertical groove 1701, the horizontal groove 1702, the oblique groove 1703, and the reset groove 1704 are connected end to end, and a blocking plate 32 is elastically rotatably mounted at the connection between the oblique groove 1703 and the reset groove 1704. For details, please refer to Figure 11 The above-mentioned baffle plate 32 is connected to the trigger block 17 through the elastic sheet 31. In the initial state, under the action of the elastic sheet 31, the baffle plate 32 is collinear with the inclined groove 1703, and the protruding column 2701 is located at the connection between the inclined groove 1703 and the reset groove 1704.

[0044] Combined with the above, combined Figure 5、 Figure 9 Description: When the second driving rod 13 rotates, the belt 19 drives the mounting plate 1901 to move toward the right. During this process, the protruding column 2701 slides along the inclined groove 1703 under the guidance of the blocking plate 32. During the sliding process, the contact and extrusion of the inclined groove 1703 on the protruding column 2701 can force the moving rod 27 to gradually move away from the belt 19. During this process, the second spring 29 is further squeezed, and the first insertion rod 30 extends toward the outside of the deflection sleeve 24, and drives the deflection sleeve 24 to rotate counterclockwise. That is, the deflection sleeve 24 can force the second insertion rod 34 to rotate counterclockwise and at the same time force the second insertion rod 34 to extend outward from the deflection sleeve 24. At this time, due to the restriction of the through slot 801 on the telescopic plate 23, the second insertion rod 34 can drive the telescopic plate 23 to slide outward from the L-shaped plate 8 until the protrusion 2701 moves to contact the horizontal slot 1702. The compression of the second spring 29 reaches its maximum, and the extension distance of the telescopic plate 23 reaches its maximum, and the telescopic plate 23 is inserted between the turned-up paper and the remaining paper on the right side. Then, as the mounting plate 1901 continues to move, the telescopic plate 23 can drive the turned-up page to continue to flip toward the left, until the protruding post 2701 is about to move to the end of the horizontal groove 1702, and the ball on the inner wall of the movable sleeve 25 on the third driving rod 14 engages with the third rotating groove 1402. Subsequently, as the mounting plate 1901 continues to move, the third driving rod 14 rotates clockwise synchronously. In particular, a rotating rod 26 is coaxially fixedly provided on the third driving rod 14, and a sleeve 901 is sleeved on the rotating rod 26. The sleeve 901 is fixedly provided on the movable frame 9, and a protrusion 903 is formed on the inner wall of the sleeve 901. The protrusion 903 is slidably provided in the second rotating groove 2601 provided on the outer wall of the rotating rod 26. When the third driving rod 14 rotates clockwise, the second rotating groove 2601 contacts and presses the protrusion 903, forcing the sleeve 901 to drive the movable frame 9 to slide toward the right side of the music board 5 until the protrusion 2701 moves to the end of the horizontal groove 1702. The pressing plate 20 on the movable frame 9 separates from the paper on the left side of the music sheet. At the same time, the second spring 29 releases its elastic potential energy, forcing the movable rod 27 to move rapidly toward the belt 19 and causing the protrusion 2701 to engage with the return groove 1704. At this time, the movable sleeve 25 moves to the end of the travel of the first driving rod 12. Then the trigger assembly reverses and forces the movable sleeve 25 to move in the opposite direction. During this process, the third drive rod 14 and the second drive rod 13 rotate in the opposite direction synchronously. During this process, the pressing plate 20 slides in the opposite direction. During the sliding process, the pressing plate 20 moves a distance away from the music board 5 with the cooperation of the threaded rod 21 and the threaded sleeve 22, so that the pressing plate 20 can press the left side of the music score after turning the page. At the same time, the second drive rod 13 forces the belt 19 to rotate in the opposite direction, which can pull the mounting plate 1901 to reset: during the resetting process, the protrusion 2701 slides along the reset groove 1704 and can push the baffle plate 32 to deflect until the protrusion 2701 returns to the initial position. The baffle plate 32 returns to the initial position under the action of the elastic sheet 31.

[0045] After the second driving rod 13 stops rotating, the first driving rod 12 rotates in the opposite direction, which can drive the deflection rod 7 to rotate in the opposite direction. After the first driving rod 12 stops rotating, the deflection rod 7 drives the deflection plate 6 back to the initial position. At this time, the adhesive disc 601 on the deflection plate 6 can contact the paper on the right side of the music score again to facilitate the next page turning.

[0046] For details, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The trigger assembly includes a guard plate 101 fixedly arranged on the bottom supporting member 1, and a slide rod 15 is fixedly arranged in the guard plate 101. The slide rod 15 is symmetrically arranged in two groups along the width direction of the bottom supporting member 1. A first spring 16 is slidably arranged on each of the two groups of slide rods 15. One end of the first spring 16 abuts against the bottom supporting member 1, and the other end abuts against the wedge block 3 slidably arranged on the two groups of slide rods 15. For details, please refer to Figure 5 , the wedge block 3 is connected to the movable sleeve 25 through a connecting rod 4, and the wedge block 3 cooperates with the pedal 2 slidably arranged on the bottom supporting member 1; In particular, the wedge block 3 and the pedal 2 are both configured to have a "right-angled trapezoidal structure", the inclined surface of the wedge block 3 is configured as the abutment surface 301, and the inclined surface of the pedal 2 is configured as the triggering surface 201. In the initial state, the first spring 16 is in a compressed state, and the compressed first spring 16 pushes the wedge block 3 toward the right side of the bottom support member 1 (refer to Figure 3 At this time, the wedge block 3 can push the pedal 2 away from the ground; when it is necessary to turn the page of the music score, the performer steps down on the pedal 2 with force, and then the trigger surface 201 of the pedal 2 and the abutment surface 301 of the wedge block 3 are in contact and squeezed, forcing the wedge block 3 to move to the left. At this time, under the connection of the connecting rod 4, the wedge block 3 can drive the movable sleeve 25 to move to the left (that is, the above reference Figure 5 When the page is turned, the pedal 2 is released, and the first spring 16 releases its elastic potential energy, which can push the wedge block 3 to reset. At the same time, the pedal 2 returns to its initial position, and the movable sleeve 25 is reset synchronously, which can drive the deflection rod 7, the movable frame 9, the mounting plate 1901 and the telescopic plate 23 to reset so that the range operation can be performed next time; It is particularly important to note that the above-mentioned stepping process is relatively short, so the page turning operation of the music score is relatively fast and will not affect the performer. At the same time, the music score is relatively thin, so the music score will not automatically fold during the process of the page starting piece and the movement of the pressing plate 20.
