[0032] Reference Figure 1 As shown, the utility model provides a technical solution: a digital piano music stand, comprising an adjustment frame 1 and a placement plate 4, characterized in that a fixing device 2 is provided on the outside of the placement plate 4, and a supporting device 3 is provided on the outside of the placement plate 4.

[0033] The specific configuration and functions of the fixing device 2 and the supporting device 3 will be described in detail below.

[0034] Reference Figure 2 and Figure 3As shown, in this embodiment, the fixing device 2 includes two U-shaped plates 201, one side of each of the two U-shaped plates 201 being fixedly connected to the placement plate 4. Two T-shaped slots 202 are provided on the inner side of the U-shaped plates 201, and T-shaped blocks 203 are slidably connected to the inner sides of the T-shaped slots 202. A movable plate 204 is fixedly connected to the side of the two T-shaped blocks 203 that are close to each other. Two telescopic rods 205 are fixedly connected to one side of the movable plate 204. The output ends of the two telescopic rods 205 are fixedly connected to a pressure plate 207. The arc surfaces of the telescopic rods 205 are covered with springs 206. The two ends of the two springs 206 are fixedly connected to the movable plate 204 and the pressure plate 207, respectively. A handle 209 is fixedly connected to one side of the pressure plate 207. This achieves the effect of pulling the pressure plate 207 away from the U-shaped plates 201, exerting tension on the pressure plate 207, and thus placing the springs 206 and the telescopic rods 205 in a stretched state. One side of the U-shaped plate 201 is fixedly connected to a fixed plate 211, and one side of the fixed plate 211 is fixedly connected to an internal threaded ring 212. The U-shaped plate 201 and the fixed plate 211 are fixed, and the internal threaded ring 212 is fixed to the fixed plate 211. The internal thread of the internal threaded ring 212 is connected to a threaded rod 213, and one end of the threaded rod 213 is fixedly connected to a rotating block 214. The rotating block 214 rotates to drive the threaded rod 213 to rotate and adjust in the internal threaded ring 212. One side of the movable plate 204 is fixedly connected to an L-shaped plate 208, and both ends of the U-shaped plate 201 are fixedly connected to a limiting plate 210. The L-shaped plate 208 and the limiting plate 210 are fixed to the movable plate 204. One side of the pressure plate 207 is fixedly connected to two round rods 215, and the arc surfaces of the two round rods 215 are slidably connected to the movable plate 204. The pressing plate 207 moves to drive the round rod 215 to slide on the moving plate 204.

[0035] Reference Figure 4 As shown, in this embodiment: the support device 3 includes a mounting plate 31, one side of the mounting plate 31 is fixedly connected to the placement plate 4, and both ends of the mounting plate 31 are fixedly connected to a fixing rod 32. The fixing rod 32 and the mounting plate 31 are fixedly fixed. One end of the fixing rod 32 is fixedly connected to a limiting block 37, and the circular arc surface of the fixing rod 32 is rotatably connected to the rotating cylinder 33. The limiting block 37 limits the rotating cylinder 33 from separating from the fixing rod 32. The circular arc surface of the rotating cylinder 33 is fixedly connected to an L-shaped block 34, and one end of the L-shaped block 34 is fixedly connected to an L-shaped support plate 35. The L-shaped support plate 35 and the L-shaped block 34 are fixed, and the L-shaped block 34 rotates around the rotating cylinder 33. The long arm end of the L-shaped support plate 35 is fixedly connected to an anti-slip pad 36, and the anti-slip pad 36 is made of rubber. The anti-slip pad 36 increases the friction force.

[0036] Working principle: When it is necessary to fix the music score placed on the placement plate 4, the operator first places the music score on the surface of the placement plate 4, moves the pressure plate 207, so that the pressure plate 207 is at the edge of the music score, and then pulls the pressure plate 207 in the direction away from the placement plate 4. The pressure plate 207 is subjected to tension and drives the spring 206 and the telescopic rod 205 to stretch. When the pressure plate 207 is away from the placement plate 4, the pressure plate 207 is moved in the direction close to the music score so that the edge of the music score is directly under the pressure plate 207, and the pressure plate 207 is released. At this time, the spring 206 and the telescopic rod 205 rebound and drive the pressure plate 207 to squeeze and fix the music score. The fixing device 2 solves the problem that the traditional piano music stand has no fixing measures for the music score on the music score placement plate 4, which results in the music score easily falling off the placement plate 4 when the piano is played and the music score is turned over, resulting in mistakes in playing.

[0037] When it is necessary to place a lamp for illuminating the sheet music through the support device 3, the operator first moves the L-shaped block 34 and adjusts the distance between the L-shaped block 34 and the mounting plate 31, thereby moving the L-shaped support plate 35 to accommodate the placement of lamps of different models and sizes. After adjusting to the required distance, the lamp can be placed on the anti-slip mat 36 to illuminate the sheet music placed on the placement plate 4. The support device 3 solves the problem that the traditional piano music stand does not have a placement component for the lamp, which makes it inconvenient to place the lamp when the sheet music is insufficiently illuminated, resulting in unclear viewing of the sheet music.
