Including screw rod, described screw rod one end sequentially passes through cast iron plate and soundboard and is spirally connected with qin frame, and it is solid that the screw rod upper end is equipped with first
Determine part, and screw rod lower end is equipped with the second fixing piece, first fixing piece is located on the outside of cast iron plate, and the first fixing piece is socketed in
On screw rod, second fixing piece is between soundboard and qin frame, and second fixing piece one end passes through soundboard solid with fastening nut
Surely it is spirally connected.
Preferably, first fixing piece and the second fixing piece are spirally connected by screw thread and screw rod.
Preferably, one end of first fixing piece and the second fixing piece is equipped with adjusting nut.
Preferably, the described one end of second fixing piece far from adjusting nut is equipped with screw thread.
Preferably, the screw rod is located at the end on the outside of cast iron plate equipped with interior hexagonal groove.
Preferably, spring is equipped between the cast iron plate and soundboard, and spring is socketed on screw rod.
Compared with prior art, the utility model has the beneficial effects that：The utility model is by being arranged the first fixing piece, the
Two fixing pieces and screw rod with interior hexagonal groove, soundboard can be fixed, pass through by the second fixing piece and fastening nut
Turn the first fixing piece just be adjusted the distance between cast iron plate and soundboard, by sleeve come turn screw rod just be adjusted soundboard and
The distance between qin frame.Compared with traditional piano cast iron plate is fixedly connected with screw, the utility model is easy to use, adjusts letter
It is single.
