DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: In order to solve the technical problems that the music score cannot be stably placed during page turning and the music score information is not accurately displayed during page turning, the following technical solution is proposed:

[0030] Reference Figure 1-6 and Figure 8 In this embodiment, an adjustable piano sheet music rack includes a rear support plate 1 and a front lining plate 2. The front lining plate 2 is arranged on the front side of the rear support plate 1, and a card slot 3 is vertically opened in the middle of the front side of the rear support plate 1 and the front lining plate 2, and vertical raised strips are arranged at both ends of the front side of the front lining plate 2; a slide groove 17 is opened in the middle of the front side of the front lining plate 2, and the front lining plate 2 is provided with a clamping assembly through the slide groove 17, and the clamping assembly includes an inner card plate 6 and an outer card plate 7, the inner card plate 6 and the outer card plate 7 are slidably connected, and the inner ends are respectively provided with arc plates 2 9 and arc plates 1 8 facing opposite directions, and the clamping assembly is used for placing piano sheet music; a supporting assembly is arranged on the rear side of the rear support plate 1, and the supporting assembly is used for setting the piano sheet music placement angle.

[0031] The clamping assembly also includes a moving seat 10, both ends of the moving seat 10 are equipped with moving blocks 15 matching the "L"-shaped slide groove 17, and both sides of the moving block 15 are provided with limit blocks 16, and the limit blocks 16 are in contact with the vertical raised strips on both sides of the front of the front lining plate 2. The moving seat 10 extends to the front side of the front lining plate 2 and is connected to the inner card plate 6 at one end, and the outer end of the outer card plate 7 is connected to the cloth bag 19, and the outer card plate 7 extends to the cloth bag 19 and is provided with a steering plate 22, and the rear side of the cloth bag 19 is connected to a sleeve 1 that is sleeved with the inner card plate 6. 8, wherein the outer card plate 7 is connected to the sleeve 18 through the cloth bag 19. When a thicker music score needs to be turned and pressed, the outer card plate 7 is rotated 180° in the cloth bag 19 to change the direction of the inner concave surface of the arc plate 18 of the outer card plate 7. At this time, the arc plate 18 makes a relatively tight pressing on the music score page, and the inner concave surfaces of the arc plate 18 and the arc plate 2 9 are far away from each other in the initial position, which facilitates the music score to be quickly and accurately inserted inward between the inner card plate 6 and the outer card plate 7, reducing the complexity of the page turning action;

[0032] A magnetic stripe 21 is arranged on the front side of the inner card plate 6 near the arc plate 29, and a plurality of magnetic stripes 1 20 are arranged on the rear side of the outer card plate 7 near the arc plate 1 8. When the music score page is inserted between the inner card plate 6 and the outer card plate 7, the music score is stably adsorbed by the attraction between the magnetic stripe 1 20 and the magnetic stripe 2 21, and the outer card plate 7 can also move horizontally on the inner card plate 6 through the cloth bag 19 and the sleeve 18, thereby changing the pressing position of the magnetic stripe 1 20 and the magnetic stripe 2 21 relative to the music score, and making adaptive adjustments to the pressing position of music scores of different specifications and used in different occasions, wherein different occasions, such as the indoor air-conditioning blowing area and the outdoor natural wind blowing area, have different pressing position adjustment requirements;

[0033] Basic principle: Figure 1 and Figure 2 It is explained that when different users place music scores of different specifications, the bottom of the music score and the book spine can form a preliminary limit, and the book edges can be stably pressed to ensure that the current display content of the music score can be stably and continuously displayed. At the same time, the music score can be turned with one hand without causing excessive page turning of other pages. At the same time, the support component with tiltable adjustment of the music score placement angle can effectively meet the needs of the performer. The mutual use of the two makes the music score have the function of being stably placed according to the required specifications, and also has the advantage of not producing a joint turning effect during the page turning process, with fewer operation steps and simple movements.

[0034] The following is a detailed description. When placing: first, the spine of the music score is aligned with the card slot 3, and the outer side of the page after turning is abutted against the anti-drop rod 5. According to the specifications of the music score and the width of the page after unfolding, the position of the movable seat 10 inside the slide slot 17 is adjusted, and the unfolded side of the music score is inserted between the inner card plate 6 and the outer card plate 7. The inner card plate 6 and the outer card plate 7 are constantly approached to complete the fixation of the unfolded side of the music score, and then the other side of the unfolded music score is fixed in the same way; if the height of the music score is high, it is necessary to unfold the extension rod 28 to a vertical state to complete the support of the top of the rear side of the music score and complete stable placement;

[0035] When turning pages: at this time, both sides of the music score are stuck between the inner card plate 6 and the outer card plate 7. When it is necessary to turn the page, use your fingers to lightly flick the edge of the page to be turned. At this time, the edge of the page to be turned of the music score is subjected to force and moves outward, and the pages below the page to be turned will not be affected by the turning force and will not be turned together. The page turning is completed by turning a single page with one hand, and then the turned page is inserted between the inner card plate 6 and the outer card plate 7 on the other side with one hand. The placement is stable, the movements are simple during the page turning process, and there are few fixed steps.

[0036] Embodiment 2: This embodiment is based on the embodiment 1, and achieves an angle suitable for the performer to watch by changing the tilt angle when the music score is placed, as follows:

[0037] Reference Figure 7 - Figure 8 , including a support assembly including a rotating seat 11 and a bottom rod 13, the rotating seat 11 is fixedly installed at the middle of the rear side of the rear support plate 1, the supporting plate 12 is rotatably installed on the rotating seat 11, the bottom rod 13 is arranged at the bottom of the supporting plate 12, a pin rod 24 is inserted on the rotating seat 11, one end of the pin rod 24 is rotatably installed with a positioning seat 23, and a spring 25 is sleeved on the outer side of the end of the pin rod 24 away from the positioning seat 23, and the two ends of the spring 25 are respectively abutted against the rotating seat 11 and the pin rod 24, wherein the rotating seat 11 is a rubber seat, and when the arc surface of the positioning seat 23 abuts against the rotating seat 11, one side of the rotating seat 11 is deformed, thereby clamping the top of the supporting plate 12, so that it cannot complete the rotation to achieve the positioning purpose;

[0038] The lower end of the pin rod 24 is connected to a lever 26 . The support plate 12 is triangular in shape, and both ends of the bottom rod 13 extending to the outer side of the bottom of the support plate 12 are sleeved with latex rings 14 .

[0039] When adjusting the inclination: the arc surface of the positioning seat 23 is moved to a position away from the side of the rotating seat 11 by the lever 26. At this time, after the pin rod 24 is separated from the contact between the arc surface of the positioning seat 23 and the rotating seat 11, the spring 25 restores its original length and no longer clamps the top of the support plate 12. At this time, the support plate 12 is rotated. After the support plate 12 drives the bottom rod 13 to complete the inclination adjustment, the arc surface of the positioning seat 23 is restored to contact with the side of the rotating seat 11, so that the positioning seat 23 presses the rotating seat 11 to fix the top of the support plate 12. At this time, the music score placed on the front side of the inner lining plate 2 is stably placed after the angle inclination is adjusted.

[0040] Example 3: Reference Figure 1 - Figure 8 This embodiment combines the technical contents of the first embodiment and the second embodiment to form the following usage method:

[0041] Step 1: Align the spine of the music score with the card slot 3, and the outer bottom of the page after turning over is in contact with the anti-drop rod 5, adjust the position of the movable seat 10 inside the slide slot 17, insert the unfolded side of the music score between the inner card plate 6 and the outer card plate 7 to fix the unfolded side of the music score, and then fix the unfolded side of the music score in the same way; if the height of the music score is high, it is necessary to unfold the extension rod 28 to a vertical state to support the top of the back side of the music score and complete the stable placement;

[0042] Step 2: When it is necessary to turn the page, use your fingers to lightly flick the edge of the page to be turned. At this time, the edge of the page to be turned of the music score is stressed and moves outward, and the pages below the page to be turned will not be affected by the turning force and will not be turned together. The page can be turned by one hand and one page at a time, and then the turned page can be inserted between the inner card plate 6 and the outer card plate 7 on the other side with one hand. The placement is stable, the action is simple during the page turning process, and there are few fixed steps.

[0043] Step 3: Move the arc surface of the positioning seat 23 to a position away from the side of the rotating seat 11 through the lever 26. At this time, the pin rod 24 no longer clamps the top of the support plate 12 after it is separated from the abutment between the arc surface of the positioning seat 23 and the rotating seat 11. At this time, the rotating support plate 12 drives the bottom rod 13 to complete the tilt adjustment, and then restores the abutment between the arc surface of the positioning seat 23 and the side of the rotating seat 11, so that the positioning seat 23 presses the rotating seat 11 to fix the top of the support plate 12. At this time, the music score placed on the front side of the inner lining plate 2 is stably placed after the angle tilt adjustment.

[0044] The scheme effects are as follows:

[0045] When different users place musical scores of different specifications, the bottom of the musical score and the spine of the book can form a preliminary limit, and the book edges can be stably pressed to ensure that the current display content of the musical score can be stably and continuously displayed, and at the same time, turning the pages of the musical score can be completed with one hand without causing excessive page turning of other pages; the support component with tiltable adjustment of the musical score placement angle can effectively meet the needs of the performer, and the mutual use of the two makes the musical score have the function of stable placement according to the required specifications, and also has the advantage of no associated turning effect during page turning, combined with placement and quick fixation after turning the pages to achieve fast-paced use, with few operating steps and simple movements.
