Description

Piano key-pressing gear with stable structure Technical Field The utility model relates to the technical field of piano key pressing blocks, in particular to a piano key pressing block with a stable structure. Background The key pressing gear is a structure in the piano, can press and block keys in the piano, ensures that the keys cannot rise excessively when the piano is played, can also adjust the sound of the piano, and is an indispensable structure in the piano. Because the key-pressing block is longer and is of a wooden structure, only two ends of the key-pressing block are fixed, deformation is easy to generate, and meanwhile, the key-pressing habit of a player has great influence on the key-pressing block. If the force of the keys is too large and uneven when a player plays, some keys are often subjected to excessive pressure, so that the partial bearing pressure of the key pressing bars exceeds the bearing range, and deformation is caused, and in view of the problem that the key pressing bars are easy to deform in the prior art due to the fixed length and two ends of the key pressing bars, the utility model aims to provide a stable structure capable of providing auxiliary support in the middle part of the span of the key pressing bars or at the required reinforced part. Disclosure of utility model The utility model aims to provide a piano key pressing gear with stable structure, which solves the problems in the background technology.
