Description

Technical Field

[0001] The utility model relates to the technical field of pianos, in particular to a piano music stand which is convenient for turning pages. Background Art

[0002] When people play the piano, they generally need to use a piano music stand to support the music scores so that they can check them.

[0003] Patent document CN218384482U discloses a piano music stand for convenient page turning of piano scores, "including a music stand and two adjustment slots, wherein the adjustment slots are arranged on the front side of the music stand, and the inner cavity of the adjustment slots is movably connected with an adjustment plate. The utility model arranges the adjustment slots, the adjustment plates, the receiving slots, the docking device, the movable hole, the pull plate, the pressure plate, the sleeve plate, the sleeve rod and the docking slot for coordinated use. After the adjustment plate is pushed to drive the pressure plate to press the page tightly, the pull plate is released, and the spring undergoes elastic deformation to drive the movable plate back to its original position. The movable plate moves to drive the card rod to pass through the receiving slot to the docking slot, so that the piano score can be turned conveniently, which solves the problem that the existing piano music stands all use a long spring sleeved on a piano when positioning the piano score pages. The long rod is used to clamp the piano score page. When turning the page, the fingers need to pull the long rod, which is a laborious process. Sometimes, if the fingers slip, the bending force of the spring drives the long rod to instantly hit the piano score, which may cause the paper to be damaged. "In the piano music stand, the piano score is generally placed directly on the front side of the music stand. If the piano score is a piano score book with a certain thickness, the spine of the opened piano score book cannot be fixed, so that when the player operates the pressure plate to leave the piano score to turn the page, the piano score will shake and close. In addition, the position of the pressure plate is fixed, and it cannot fix the piano score books of different sizes, which is of low practicality. For this reason, we propose a piano score stand that is easy to turn the page to solve the above problems. Utility Model Content
