摘要

The present invention relates to a detachable structure of a muffler for piano, the technical configuration of which is connected between the mounting piece (6) and the paddle (2) of the piano, the connecting piece (20) (21) which is provided at the center and one side of the lower part of the keyboard The brackets 19 and 22 are interlocked and fixed to the piano, respectively, and the paddles 2, the connecting pieces 20, and the connecting pieces 21 and the mounting pieces 6 are interposed therebetween via turnbuckles 2 and 3, respectively. By connecting the link 4, the spring 16 is coupled to the bottom of one end of the mounting piece (6) and the coupling piece 24, the mounting piece (6) so that the end of the link (4) can be inserted Link (4) is inserted to form the insertion groove 12 in the), the end of the link 4 is inserted into the adjustment bolt 11 through the elastic piece 10.;Therefore, it is extremely easy to manufacture with a simple configuration that rotates the mounting piece up and down by the link and the connecting piece, and facilitates the adjustment of the operating force by the turn buckle connecting the link, interposed between the mounting piece and the coupling plate When the pedal is stepped on and released by the spring, the operation is completed as well as vibration and noise are prevented accordingly.
