DETAILED DESCRIPTION

[0019] like Figure 1 , Figure 2 and Figure 4 As shown, a music composition book fixing plate includes a connecting plate 1, a supporting rod 2 and a bearing mechanism 3. The supporting rod 2 is fixedly connected to both ends of the connecting plate 1, and the supporting rod 2 is bent in an arc shape in the middle section. A sliding groove 4 is opened on the relative inner side walls of the supporting rod 2, and a positioning hole 5 is opened in the sliding groove 4. The positioning holes 5 are evenly spaced along the length direction of the supporting rod 2. The bearing mechanism 3 is slidably arranged in the sliding groove 4 and plugged into the relative positioning holes 5. The bearing mechanism 3 is arranged and installed along the length direction of the sliding groove 4, and its sliding adjustment and positioning installation are realized by rotating the bearing mechanism 3 in the positioning hole 5.

[0020] like Figure 1-6 As shown, in order to support the music score and meet the movement and adjustment of the music score in different states, so that it can meet the support of music score writing and the positioning support of music score during performance practice, the bearing mechanism 3 includes a support plate 6, a support tube 7 and a locking assembly 8. The two ends of the support tube 7 are slidably arranged in the slide groove 4. The centers of the two end surfaces of the support tube 7 are provided with limit grooves 9. The centers of the inner parts of the limit grooves 9 are provided with blind holes 10. The support plate 6 is fixedly connected to the outer side wall of the support tube 7. The locking assembly 8 is slidably arranged in the limit grooves 9 at the two ends of the support tube 7. The locking assembly 8 is connected and positioned with the positioning hole 5 through the extension and contraction of the locking assembly 8. Multiple support tubes 7 are slidably adjusted in the slide groove 4. The locking assembly 8 is plugged and fixed with the positioning hole 5, so that the support plates 6 can be arranged closely or separately.

[0021] The locking assembly 8 includes a slide bar 11 and a latch 12. The slide bar 11 is slidably disposed in the blind hole 10. The latch 12 is slidably disposed in the limiting groove 9. One end of the slide bar 11 is fixedly connected to the latch 12. The end of the latch 12 away from the slide bar 11 is arranged in an inclined surface. A limiting spring 13 is wound around the outer wall of the slide bar 11. The limiting spring 13 is fixedly connected between the latch 12 and the inner wall of the limiting groove 9. When the position of the support tube 7 needs to be adjusted, the support plate 6 and the support plate 6 are rotated. , the locks 12 at both ends of the support tube 7 rotate so that the oblique sides of the locks 12 contact the side walls of the positioning hole 5 in the moving direction. When the support tube 7 is pushed to move in the slide groove 4, the locks 12 shrink and enter the limiting groove 9, and the slide rod 11 slides in the blind hole 10. At the same time, the limiting spring 13 is compressed. When the lock 12 moves to the next positioning hole 5, the lock 12 pops out under the support of the limiting spring 13, and is plugged and fixed with the positioning hole 5, supporting the side of the lock 12 away from the inclined surface.

[0022] Among them, an adjustment groove 14 is opened inside the support plate 6, and the adjustment groove 14 is symmetrically arranged with the support tube 7 as the center. A limit rod 15 is slidably arranged in the adjustment groove 14, and the limit rod 15 is in friction contact with the inner wall of the adjustment groove 14. The upper part of the symmetrical limit plate 16 is fixedly connected with the limit plate 16, and the limit rod 15 slides left and right in the adjustment groove 14. The limit rod 15 has a positioning function through the friction connection. The area of ​​the limit plate 16 is larger than the limit rod 15, and a limiting area is formed between the two sides of the limit rod 15 and the bottom wall of the limit plate 16, which is used to press and position its edge after turning the page of the music score.

[0023] When in use, the creator can place the device on a musical instrument or a desktop. When creating a score, the creator can pull multiple bearing mechanisms 3 to be centrally positioned at one end of the symmetrical support rod 2 parallel to the desktop to support the score, making it easier for the creator to write the score.

[0024] Rotate the support plate 6 and the support plate 6, and the locks 12 at both ends of the support tube 7 rotate, so that the oblique side of the lock 12 contacts the side wall of the positioning hole 5 in the moving direction, and when the support tube 7 is pushed to move in the slide groove 4, the lock 12 contracts and is in the limit groove 9, and the slide rod 11 slides in the blind hole 10, and the limit spring 13 is compressed at the same time. When the lock 12 moves to the next positioning hole 5, the lock 12 pops out under the support of the limit spring 13, and is plugged and fixed with the positioning hole 5, supporting the side of the lock 12 away from the inclined surface;

[0025] After writing, when the music score is played, in order to facilitate observation of the music score, multiple supporting mechanisms 3 are pushed to move between the symmetrical support rods 2 and away from the creator. Multiple supporting mechanisms 3 are tilted on the desktop to increase the height of the music score, which is convenient for the creator to visually observe. The limit rod 15 connected by friction is slid and adjusted in the adjustment groove 14, so that the limit plate 16 is pressed on both sides of the music score to achieve the positioning of the music score.

[0026] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the scope of protection of the utility model.
