Locking device, drum frame locking device and drum including the same

The present invention relates to a locking device, a drum frame locking device and a drum comprising the same.

Press, the drum for general blow, which has a hollow drum belly, covers the drum skin at the open end of the drum belly, and covers the drum frame of the drum skin and the belly of the drum, and has a plurality of connecting portions on the outer circumference of the drum belly. In order to adjust the position of the drum cover to adjust the tightness of the drum skin, the conventional method is to snail by inserting a plurality of bolts into the plurality of perforations of the drum frame and screwing them to the connecting portions. By moving the bolts to the relative positions of the connecting portions, the position of the drum frame can be changed to adjust the tightness of the drum skin, and the tone and tone emitted by the drum when the drum is hit can be adjusted.

However, since the drum generates vibration when struck, and the drum frame of the conventional drum is in contact with the bolt, when the drum vibrates, the drum frame transmits the shock wave generated during the blow to the bolt, which easily causes the bolt to shake and loose. When the bolt is loose, the drum skin will be slack and the tone and tone of the drum will be changed. Therefore, the drum needs to be constantly re-adjusted. In addition, a machine such as an audio or a machine tool can also loosen the lock of the sound or the machine tool due to vibration, and there is a drawback that needs to be improved.
