Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument auxiliary devices, in particular to a guzheng music score stand. Background Art

[0002] The music stand is a tool designed for instrument players. Its main function is to fix and support the music so that the player can read it conveniently during performance or practice. It is generally adjustable. The player can adjust the height and angle of the music stand according to his or her height and reading habits to maintain a comfortable playing posture.

[0003] At present, most of the common music stands on the market are of upright structure, such as the Chinese utility model patent disclosed by publication number CN220694686U: a music stand. This application makes improvements on the traditional music stand, that is, this application sets a fixing device. When using the fixing device, the music cover on the surface of the music score is inserted into the inside of the connecting groove opened on the side of the fixing strip, so that the music score can be well fixed on the surface of the music stand body. However, on the one hand, the overall structure of this application is relatively large, especially when it is used for Guzheng performance, the distance between the music score and the performer is far away, thus affecting the performer's viewing of the content on the music score. On the other hand, the music score is fixed by the fixing device in this application, which leads to cumbersome operation steps when turning the pages of the music score later, and the music score cannot be fixed and turned conveniently.

An adjusting screw 9 is movably installed in the fixed plate 8, and a metal bellows 10 is movably connected between the L-shaped mounting plate 7 and one of the extension rods 4.

[0026] like Figure 1-Figure 4As shown, a first slide groove 11 is provided in the back plate 3, and the center positions of the two extension rods 4 are rotatably connected by a pin shaft, and one end of the two extension rods 4 is respectively slidably installed on the corresponding rear end of the back plate 3 through the corresponding first slide groove 11 through the pin shaft, and the other ends of the two extension rods 4 are respectively rotatably installed on the lower end of the corresponding back plate 3 through the pin shaft. The two back plates 3 can be folded, stored and unfolded through two cross-arranged extension rods 4, and a first ball seat 13 is fixedly installed at the rear end of one of the extension rods 4, and a spherical groove is provided in the first ball seat 13, and the first end plates 14 are respectively fixedly installed at one end of the two limit plates 5, and the first end plate 14 is provided with a second slide groove 16, and a telescopic plate 15 is provided at one end of the first end plate 14, and a second end is fixedly installed at one end of the telescopic plate 15. The second end plate 17 is provided with a connecting groove 18 at the other end of the telescopic plate 15, and a slider 19 is fixedly installed on one side of the second end plate 17 relative to the limiting plate 5. The transverse cross section of the slider 19 is T-shaped, and the slider 19 is inserted and installed in the second slide groove 16. The end of the limiting plate 5 away from the first end plate 14 is rotatably installed at the front end of the corresponding supporting base 12 through a pin shaft. The two ends of the connecting plate 6 are fixedly installed with fixed shafts 20, and the two ends of the connecting plate 6 are respectively rotatably installed in the connecting groove 18 of the corresponding telescopic plate 15 through the fixed shafts 20.
