Description

Upright piano with independent support bracket for center plate

Technical Field

The utility model belongs to the vertical piano field especially relates to an vertical piano with independent support holder of center plate.

Background

The structure of an upright piano (piano for short) comprises a frame and internal components; the frame comprises a mark back frame, the outer side of the mark back frame is provided with a shell, the mark back frame is suspended on the ground through the shell, the front side of the mark back frame is provided with a middle disc, and two ends of the middle disc are connected with the shell through screws; the internal components comprise a keyboard, a string striking machine, hammers, a keyboard and a linkage system, the keyboard is arranged on a middle disc, the string striking machine, the hammers, the keyboard and the linkage system are arranged on a Mark back frame, the keyboard, the hammers, the string striking machine and the linkage system are all connected with the middle disc, the middle disc is a reference platform for mounting the internal components, the stability of the middle disc is very important, if the middle disc is unstable, sinking or deformation occurs, the intonation of the piano is reduced, even some hammers can not strike the string striking machine, so that certain keys on the keyboard can not make the piano generate corresponding sound after being pressed, and the usability of the piano is affected, therefore, the stability of the middle disc determines the stability of the intonation of the piano and the stability of use to a great extent. The middle disc is connected with the shell through the screws, the middle disc is connected with the shell in a multi-point mode, the middle disc and the shell are both made of wood and are made of soft materials, and the multi-point connection causes the joint of the middle disc and the shell to be easy to deform, so that the middle disc sinks; because the shell is the bearing part of piano, the weight of mark back of the body frame, well dish and internals all need the shell to bear, and the shell takes place to warp under the action of gravity easily, and the shell deformation direct action well dish also can cause well dish to warp. Therefore, the stability of the middle disc of the existing piano is poor, and the intonation stability and the use stability of the piano are poor.

The piano needs to stand for several months for aging after the piano assembly is completed, and the piano intonation is debugged for many times during standing, so that the piano intonation can be sold after being stable enough. In actual sale, in order to meet the individual requirements of consumers, manufacturers generally make a plurality of pianos with different appearances for selection by the consumers, namely make a plurality of pianos with different shells for selection by the consumers. Because the shell belongs to a part of the composition framework, the piano can not be configured after being assembled, and the multiple pianos with different appearances need to be separately stocked, so that the total stock quantity of the multiple pianos is huge, and the capital pressure of stock of manufacturers is large.

Therefore, the existing piano has the defects of poor intonation stability, poor use stability and large stockpile fund pressure of manufacturers.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an upright piano with independent support holder of well dish. The utility model has the advantages of the intonation stability is better, the stability in use is better and the producer is equipped with goods fund pressure little, still has the short advantage of customization style delivery cycle.

The technical scheme of the utility model: including the frame, the inside internals that is equipped with of frame, frame include mark back of the body frame, and the outside of mark back of the body frame is equipped with the shell, and the front side of mark back of the body frame is equipped with the well dish, and the both sides of mark back of the body frame all are equipped with the support holder of being connected with the well dish.

In the aforesaid upright piano with independent support holder of well dish, the support holder includes the T shaped plate of compriseing diaphragm and riser, and the riser is fixed with the lateral wall of mark back of the body frame, and the diaphragm extends to the front side of mark back of the body frame, and the inboard of diaphragm front end is equipped with the angle bar, and the diaphragm passes through the adaptor to be fixed with the angle bar, well dish is fixed with the angle bar.

In the upright piano having the center independent support stand, the cross plate is fixed to the case.

Compared with the prior art, the utility model adds the supporting bracket on the basis of the prior piano, the middle disc is connected with the mark back frame through the supporting bracket, the middle disc is in surface contact connection with the mark back frame, the joint between the middle disc and the mark back frame is not easy to deform, and the middle disc is not easy to sink; the middle disc is mainly fixed on the mark back frame through the supporting bracket, and the supporting bracket is stable in structure and not easy to deform, so that the deformation of the shell cannot or hardly cause the deformation of the middle disc through the supporting bracket; because the center is difficult to sink and is difficult to warp, so the stability of center is good for the intonation stability of piano is better and stability in use is better.

The supporting bracket can fix the middle disc without supporting the shell, so that a manufacturer can assemble the mark back frame, the middle disc and the supporting bracket into a main body structure of a frame, then assemble the internal parts into the main body structure to obtain a blank of the piano, stock the blank, stand and debug the blank, assemble the corresponding shell on the blank according to the delivery requirement to obtain the corresponding style of piano, and do not need to separately stock each style of piano, thereby reducing the total stock quantity of the piano and lowering the capital pressure of the manufacturer.

Under general condition, piano structure changes and reduces piano tone quality easily, and this is also the main reason that the piano continues to use current structure always, and the producer is reluctant to go to try to change the piano structure, but through the experiment, the applicant discovers, the utility model discloses a tone quality does not reduce in the tone quality of current piano.

In another case, the piano style is produced by the customer, and a shell with a specific shape is required to be manufactured according to the order, and the existing piano needs to be assembled and statically debugged after the shell is produced, so that the delivery period is long. And the utility model discloses can assemble the base article that obtains the piano in advance before customer's order is assigned, to the base article debugging that stews, carry out the stock, wait the shell production and accomplish the back, directly install the shell on the base article and can shipment, reduced the delivery cycle of piano greatly.

Therefore, the utility model has the advantages of the intonation stability is better, the stability in use is better and producer's stock fund pressure is little, still has the advantage that customization style delivery cycle is short.
