For this purpose, we release and a kind of being fixedly connected with screw using more easily piano cast iron plate to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of piano cast iron plates to be fixedly connected with screw, to solve above-mentioned background technology The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions:A kind of piano cast iron plate is fixedly connected with screw, 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.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the mounting structure schematic diagram of the utility model;
Fig. 3 is the screw rod end construction schematic diagram of the utility model.
In figure:1 screw rod, 2 cast iron plates, 3 soundboards, 4 qin framves, 5 first fixing pieces, 6 second fixing pieces, 7 fastening nuts, 8 are adjusted Save nut, hexagonal groove, 10 springs in 9.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1-3, the utility model provides a kind of piano cast iron plate and is fixedly connected with screw technique scheme, including spiral shell Bar 1,1 one end of the screw rod sequentially pass through cast iron plate 2 and soundboard 3 and are spirally connected with qin frame 4, and it is solid that 1 upper end of the screw rod is equipped with first Determine part 5, and 1 lower end of screw rod is equipped with the second fixing piece 6, first fixing piece 5 is located at 2 outside of cast iron plate, and the first fixing piece 5 It is socketed on screw rod 1, second fixing piece 6 is between soundboard 3 and qin frame 4, and 6 one end of the second fixing piece passes through soundboard 3 It is spirally connected with the fixation of fastening nut 7.
Specifically, first fixing piece, 5 and second fixing piece 6 is spirally connected by screw thread and screw rod 1.
Specifically, one end of first fixing piece, 5 and second fixing piece 6 is equipped with adjusting nut 8.
