To achieve these goals, the technical solution of the utility model is as follows:
One has hand-type error prompting function and height-adjustable piano, including keyboard with for correcting rectifying of hand-type function
Equipment；Described keyboard is fixed on keyboard drawer；Described apparatus for correcting is fixed on described keyboard drawer；Described rectification fills
Put and include a pressure pin；It is fixed on described keyboard drawer by location bar at the two ends of described pressure pin and is provided with on described pressure pin
Pressure transducer；Described pressure transducer is connected with controller；Described controller and a siren connect；Described keyboard drawer
It is fixed on piano frame；It is provided with adjusting the lifting assembly of piano height in the bottom of described piano frame；Described liter is come down to a lower group
Part includes being built in the Retractive leg bottom described piano frame, and is arranged on the roller bottom described Retractive leg.
Preferably, described keyboard drawer includes the supporting plate of both sides and the backing of bottom；Described location bar is fixed on described supporting plate；
Described pressure pin is higher than backing.
Preferably, described pressure pin is in below wrist when abecedarian plays the piano, and the wrist lifting abecedarian is in normal level.
Preferably, bar end fixing with described supporting plate in described location is less than the fixing end of described location bar and described pressure pin.
Preferably, described pressure pin and wrist contact surface are cambered surface.
Preferably, described location bar is fixed with described supporting plate by bolt.
Preferably, described pressure transducer is fixed on the contact surface of described pressure pin and wrist.
Preferably, the length that described pressure transducer covers on described pressure pin is equal with the length of described keyboard.
Preferably, described roller is the universal wheel with auto-lock function.
This utility model compared with prior art, has the advantages that
Arranging pressure pin by the lower section in wrist, make abecedarian when playing the musical instrument, pressure pin is as object of reference, it may be determined that wrist
Position, i.e. wrist will not be pressed down, also will not on lift；It is easy to the hand-type rapid shaping of abecedarian.The upper surface of cambered surface, it is to avoid
Sharp corner angle are had to fray the tender and lovely skin of child；
By arranging pressure transducer, when wrist exceedes certain numerical value to the pressure of pressure pin, controller will be sent out to siren
Going out information, siren will send alarm, reminds and presses severity under piano practicer's wrist, it should be noted that hand-type；
By Retractive leg and universal wheel, can easily realize adjusting height and the position of piano, to adapt to the exercise of different height
Person, also allows for moving position.

Detailed description of the invention
By making, architectural feature of the present utility model and effect of being reached are had a better understanding and awareness, in order to preferably
Embodiment and accompanying drawing coordinate detailed description, are described as follows:
One has hand-type error prompting function and height-adjustable piano as shown in Figure 1 and Figure 2, including keyboard 1 and for
Correct the apparatus for correcting 2 of hand-type function；Keyboard 1 is fixed on keyboard drawer 3；Apparatus for correcting 2 is fixed on keyboard drawer 3；
Apparatus for correcting 2 includes a pressure pin 21；It is fixed on keyboard drawer 3 by location bar 22 at the two ends of pressure pin 21.At pressure pin
Being additionally provided with pressure transducer 23 on 21, pressure transducer 23 is connected with controller (not shown), controller and report
Alert device (not shown) connects.
Keyboard drawer 3 is fixed on piano frame 4；The liter being provided with adjusting piano height in the bottom of piano frame 4 is come down to a lower group
Part；Lifting assembly includes the Retractive leg (not shown) being built in bottom piano frame, and is arranged on the rolling bottom Retractive leg
