Abstract
The invention discloses a metal upright post for a grand piano, which is used for supporting a body of the grand piano. When a piano is played, the hammer strikes the strings, vibration waves generated by the strings are transmitted to the soundboard through Ma Qiaochuan, resonance generated by the soundboard is the sound, the soundboard is bonded with the back frame of the whole piano, the whole piano body is vibrated, and the vibration waves are transmitted to the metal upright post and reach the resonance cavity to generate resonance effect.
Description
Technical Field
The invention relates to a metal upright post, in particular to a metal upright post for a grand piano.
Background
With the progress and development of society, people are pursuing fashion, pursuing mental life and simultaneously paying more attention to personal maintenance, and along with the improvement of the living standard of people, pianos have come into every family. At present, upright posts for supporting grand piano bodies are generally made of wood materials, which have the following disadvantages: 1. the upright post formed by wood materials is heavy, and the upright post is easy to damage in the repeated moving process of the grand piano. 2. The wood material shaped column has limited weight. 3. Wood materials are more susceptible to weather conditions, and over time, the studs become progressively deformed and even crack.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the metal upright post for the grand piano, which is high in bearing weight, not easy to damage and capable of forming a resonance cavity.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
the utility model provides a metal upright for grand piano, its is used for supporting the body of grand piano, the metal upright includes supporting leg and supporting bench, and the body of grand piano is born at the supporting bench up end, connects through the transition frame between supporting leg and the supporting bench, supporting bench one side is equipped with the backup plate, and the backup plate lower part extends to the up end of supporting leg, form one side open-ended resonance chamber between transition frame, backup plate and the supporting bench.
The transition frame comprises an integrally formed bottom plate and 2 side plates, the bottom plate is arranged on the upper end face of the supporting leg, two ends of the bottom plate are respectively connected with one end of the corresponding side plate, and the other end of the side plate is connected with one end of the corresponding supporting table.
The upper part of the backup plate extends out of the table top of the supporting table.
And a mounting hole is formed in the table top of the supporting table.
The mounting holes are formed at two ends of the table top of the supporting table.
The supporting legs are cylindrical supporting legs.
The cylindrical supporting legs are of solid structures.
The metal upright post is formed by aluminum alloy.
The included angle between the side plate of the transition frame and the supporting table is 30-60 degrees.
Preferably, an included angle between the side plate of the transition frame and the supporting table is 45 degrees.
According to the technical scheme, the metal upright post comprises the supporting legs and the supporting table, the body of the grand piano is supported on the upper end face of the supporting table, the supporting legs and the supporting table are connected through the transition frame, and a cavity with one surface open is formed among the transition frame, the backup plate and the supporting table, and is the resonance cavity. When a piano is played, the hammer strikes the strings, vibration waves generated by the strings are transmitted to the soundboard through Ma Qiaochuan, resonance generated by the soundboard is the sound, the soundboard is bonded with the back frame of the whole piano, the whole piano body is vibrated, and the vibration waves are transmitted to the metal upright post and reach the resonance cavity to generate resonance effect. The metal upright post is formed by metal materials, so that the bearing weight of the upright post is improved, and the upright post is preferably made of aluminum alloy materials, so that the upright post is light in material and convenient to move; on the other hand, the aluminum alloy material is not easily affected by climatic conditions and is not easily deformed and cracked. The cavity formed among the transition frame, the backup plate and the supporting table is a cavity, so that on one hand, materials are saved, and more importantly, the cavity forms an unexpected resonance cavity, and the tone effect of the piano is improved.
Drawings
The invention is described in further detail below with reference to the attached drawings and detailed description:
fig. 1 is a schematic structural view of a metal pillar for grand piano according to the present invention.
Detailed Description
As shown in fig. 1, the metal upright post for grand piano of the present invention is used for supporting the body of grand piano, the metal upright post comprises supporting legs 4 and supporting tables 1, the body of grand piano is supported on the upper end surfaces of the supporting tables 1, the supporting legs 4 and the supporting tables 1 are connected through transition frames 2, one side of each supporting table 1 is provided with a backup plate 3, the lower parts of the backup plates 3 extend to the upper end surfaces of the supporting legs 4, and resonance cavities 5 with one surface open are formed among the transition frames 2, the backup plates 3 and the supporting tables 1.
The transition frame 2 comprises a bottom plate 21 and 2 side plates 22 which are integrally formed, the bottom plate 21 is arranged on the upper end face of the supporting leg 4, two ends of the bottom plate 21 are respectively connected with one end of the corresponding side plate 22, and the other end of the side plate 22 is connected with one end of the corresponding supporting table 1.
As an implementation mode of the invention, the upper part of the backup plate 3 extends out of the table top of the supporting table 1, the extended part can be wrapped at the edge of the body, and various patterns such as figure images and the like can be designed on the whole backup plate and supporting legs, so that the aesthetic feeling of the upright post is enhanced. The shape of the backup plate 3 corresponding to the position of the transition frame 2 is matched with the shape of the resonance cavity 5, and the visual effect is better.
The table top of the supporting table 1 is provided with mounting holes 11, the mounting holes 11 are arranged at two ends of the table top of the supporting table 1, and the body of the grand piano is supported on the upper end face of the supporting table 1 through the mounting holes 11.
The supporting legs 4 are cylindrical supporting legs with solid structures, so that the bearing weight of the metal upright posts is ensured.
The stand column is formed by metal materials, the bearing weight of the stand column is improved, the stand column is preferably formed by aluminum alloy materials, the stand column is relatively light in material and convenient to move, and in addition, compared with wood materials, the stand column formed by the aluminum alloy materials is not easy to influence by climatic conditions, and deformation and cracking are not easy to occur, so that the stand column is damaged.
The included angle alpha between the side plate 22 of the transition frame 2 and the supporting table 1 is 30-60 degrees, the included angle alpha is preferably 45 degrees, and the inclined design ensures that the metal upright post has better stress effect.
