Description

Technical Field

[0001] The utility model relates to the technical field of pianos, in particular to a piano cover buffer device. Background Art

[0002] The piano is a traditional keyboard instrument, usually made of wood, steel and other materials. It consists of a series of tuning forks, each of which has a wooden or plastic keyboard connected to it. When the player presses a key on the keyboard, the corresponding tuning fork will be struck to produce a sound. The piano has a wide range of tones and can play a rich variety of music, from classical music to pop music. It is widely used in various occasions, including concerts, studio recordings, teaching and personal entertainment.

[0003] The piano cover needs to be flipped when the piano is in use and closed. The piano cover is a device that protects the key box. When closing the piano cover, due to its heavy weight, the piano cover is likely to be directly buckled on the key box, causing irreversible damage to both the key box and the piano cover. There is no buffer device at the bottom of the piano cover and the contact part of the key box, which cannot slow down the closing speed of the piano cover when it is closed. Secondly, there is no pull rod buffer device on the side of the piano cover. The piano cover is heavy, and it is more laborious to open the piano cover. When closing the piano cover, the piano cover will cause impact damage to the piano. Therefore, a piano cover buffer device is proposed to address the above problems. Utility Model Content
