Abstract
The utility model provides a level adjusting device of piano keys, comprising a middle pin arranged on a middle cross beam of a middle-disc type keyboard frame. The middle pin nail is thread-shaped, and the thread-shaped middle pin close to the middle cross beam is provided with a blocking piece. In the level adjusting device, the middle pin is changed into a thread state on the middle cross beam of the middle-disc type keyboard frame, simultaneously one blocking piece is added on the middle pin close to the middle cross beam and is used for supporting the key, the top of the middle pin does not have the turnable state with a mill or other tools, and the lifting is adjusted by rotation, so that the effect of leading the keys to be level is achieved.
Description
Technical field
The utility model relates to a kind of structure of fingerboard.
Background technology
Since piano is born, on the working method of keyboard, continuing traditional technology all the time, promptly available cushioning comes the concordant degree of adjusting key and the submergence depth of key with the way that subtracts pad.In 88 keys, each key all will carry out the process that taking off more than three times loaded onto at least in the piano manufacture process.The spent work in this work of each frame piano is a large amount of, and 30 minutes to 40 minutes time is taken in approximately each debugging work approximately.Under this still more skilled condition, can spend the longer time if not so.If this problem occurs when use, the thing of an expend energy in order to address this problem, is necessary fundamentally to reform especially.
Summary of the invention
It is a kind of easy to adjust that the purpose of this utility model is to provide, the concordant adjusting gear of piano key that degree of accuracy is high.
The purpose of this utility model is achieved in that the middle pin that comprises on the middle beam that is installed in middle disc type keyboard frame, and middle pin is a pin in the screw-like, is provided with catch near pin in the screw-like of middle beam.
The pin top is provided with the gong edge of a knife in the described screw-like.
The pin top is rectangular or square in the described screw-like.
The utility model is on the middle beam of middle disc type keyboard frame, become the screw thread state with middle pin, simultaneously adding a catch near on the middle pin of middle beam, be used for lifting key, the state that can reverse at middle pin top gong cutter of no use or other instrument, regulate lifting by rotation, thereby to making the concordant effect of key.
