The well dish on the piano is the platform of installation core and keyboard, if the well dish is insecure, can lead to core and keyboard to walk the position, and data can change and lead to intonation, tone quality, volume distortion, and the sense of touch also can change at any time and lead to various troubles.

The piano iron bar on the existing market usually adopts the design of a multi-component splicing structure, although the installation is convenient, the service life is short, the phenomena of loosening and bending of components are easy to occur, and the use is influenced.

Therefore, how to provide a piano iron bar with long service life and good supporting effect is a problem that needs to be solved urgently by the technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a long service life, the piano iron row that moreover support effect is good prevents that the well dish from warping the platform of integrative casting from the area.

In order to achieve the above object, the present invention provides the following technical solutions, including: the bottom plate, wherein, the bottom plate is the casting design of an organic whole, be equipped with perpendicular skeleton, dust hole and a plurality of musical instrument pinhole on the bottom plate, bottom plate center department is equipped with the well dish support frame, the well dish support frame is vertical and horizontal structure design with perpendicular skeleton, is integrative casting with bottom plate, perpendicular skeleton and makes.

Be equipped with the spacing groove on the perpendicular skeleton, the inside adoption of nonmagnetic rust-resistant high strength metal material of bottom plate is cast and is formed, and the skin covers there is the one deck sound absorbing material.

Preferably, in the platform with the function of preventing the central disc from deforming and integrally casting the piano iron row, a detachable dust cover is arranged on the dust hole.

Preferably, in the piano iron row with the integrally cast platform for preventing the deformation of the middle plate, the sound absorption material is damping glue.

Preferably, in the platform that the piano iron row was from taking the integrative casting of preventing the deformation of center plate, the vertical skeleton is perpendicular to the bottom plate, and is criss-cross structural design.

Preferably, in above-mentioned piano iron row is from taking the platform that prevents that the center frame warp integrative casting, both sides about the bottom plate are located to the musical instrument pinhole, and on the string both ends were fixed in the musical instrument pinhole respectively to through erecting the spacing groove on the skeleton.

According to the technical scheme, compared with the prior art, the utility model discloses a platform for preventing the central disc from deforming and integrally casting the piano iron row, which adopts the integral casting design, is an integral structure, enhances the supporting force of the central disc support frame by vertically and horizontally arranging the vertical framework and the central disc support frame, is not easy to bend when in use, and avoids the dislocation of strings by arranging the limiting grooves on the vertical framework; make the utility model have the characteristics of long service life, good supporting effect, strong deformation resistance.
