Description
Technical field
The present invention relates to a kind of lift piano of adjustable pedal height, relate in particular to the lift piano that a kind of qin pin and pedal are all liftable adjustable pedal height.
Background technology
Child learns piano, often just starts from very little, can the piano on market be all design and produce according to the height of adult, be unfavorable for child practicing qin.High in order to solve qin face in the market, the music stool height that changes, but the pedal of qin still can not adapt to the height of student.Also have plenty of and increase servicing unit, indirectly a pedal on the pedal of qin, so also very inconvenient.At present, child learns the more and more of piano, and a child starts study early and plays the piano, and grows up in sound of musical instrument along with her.Piano on market is all applicable adult, and child is sitting on music stool, less touch with the ground, hand and keyboard height improper, pin is also stepped on less than pedal.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of qin pin and pedal to be all the lift piano of liftable adjustable pedal height.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lift piano of adjustable pedal height, comprise key, sound-changing device, qin frame, key is arranged on above qin frame, sound-changing device is arranged on below qin frame, it is characterized in that, screw rod is fixed with in the bottom of described qin frame, upper screw rod connects the first half of rotating nut, Lower Half connect lower screw rod, lower screw rod is fixed on base plate, base plate installs pedal, pedal back side mounting plate, the bottom of steel wire is fixed on fixed head by locking cap, base plate connects the bottom of flexible metallic hose, be arranged in flexible metallic hose, the top of flexible metallic hose connects the bottom of qin frame, the top of steel wire connects sound-changing device, piano pin is installed in the bottom of qin frame, the built-in adjuster bar of piano foot bottom, adjuster bar connects castor.
The invention has the beneficial effects as follows, invent a kind of piano of applicable child exercise, simultaneously again not because children have grown up, waste original piano.Diminutive child also can be played the musical instrument like a cork in the present invention.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, further illustrate the structure and characteristics of the lift piano of adjustable pedal height of the present invention, in accompanying drawing:
Fig. 1 is the structural drawing of embodiments of the invention one.
Fig. 2 is the pedal structure figure of embodiments of the invention one.
Fig. 3 is the rotating nut structural drawing of embodiments of the invention one.
In figure: 1. key, 2. sound-changing device, 3. qin frame, 4. fixed head, 5. base plate, 6. flexible metallic hose, 7. steel wire, 8. pedal, 9. descend screw rod, 10. rotating nut, screw rod on 11., 12. locking caps, 13. piano pin, 14. adjuster bars, 15. castors.
Embodiment
Fig. 1, Fig. 2, embodiment illustrated in fig. 3 in, be provided with key (1), sound-changing device (2), qin frame (3), fixed head (4), base plate (5), flexible metallic hose (6), steel wire (7), pedal (8), lower screw rod (9), rotating nut (10), upper screw rod (11), locking cap (12), piano pin (13), adjuster bar (14), castor (15).
Implement the lift piano of adjustable pedal height of the present invention, comprise key (1), sound-changing device (2), qin frame (3), key (1) is arranged on above qin frame (3), sound-changing device (2) is arranged on below qin frame (3), it is characterized in that, upper screw rod (11) is fixed with in the bottom of described qin frame (3), upper screw rod (11) connects the first half of rotating nut (10), the Lower Half of rotating nut (10) connects lower screw rod (9), lower screw rod (9) is fixed on base plate (5), base plate (5) is installed pedal (8), pedal (8) back side mounting plate (4), the bottom of steel wire (7) is fixed on fixed head (4) by locking cap (12), base plate (5) connects the bottom of flexible metallic hose (6), steel wire (7) is arranged in flexible metallic hose (6), the top of flexible metallic hose (6) connects the bottom of qin frame (3), the top of steel wire (7) connects sound-changing device (2).Piano pin (13) is installed in the bottom of qin frame (3), piano pin (13) the built-in adjuster bar in bottom (14), and adjuster bar (14) connects castor (15).The first half internal thread of rotating nut (10) is positive tooth, the upper screw rod (11) that rotating nut (10) first half connects should be positive tooth, the Lower Half internal thread of rotating nut (10) is anti-tooth, and the lower screw rod (9) that rotating nut (10) Lower Half connects should be anti-tooth.
Implement the lift piano of adjustable pedal height of the present invention, first three of piano pin are all processed, built-in adjuster bar.The part of pedal, the hand brake cable on the connection analog bicycle of pedal and organ stop, when pressing rim brake, pulling middle steel wire, because the flexible metallic hose of outside supports, just can control tightening up and unclamping of rim brake, connect pedal and sound-changing device with it.
The pith of this piano is the body portion such as resonant tank, and qin pin is only supporting role, if make qin pin and pedal be all liftable, above problem just can solve.Say, sitting height when children play the piano with adult differs also just between 10cm again.The keyboard that invention solves qin and pedal can be adjusted, and child just can be made equally to facilitate experienced qin with being grown up.
Qin pin of the present invention is made adjustable, and pedal also connects with rotating nut, adjustment rotating nut and qin thumb screw, just can reach the requirement changing height.Pedal and sound-changing device use rim brake steel wire.The present invention not only can solve child and step on problem less than pedal, can also and qin chair supporting, allow the people of different height is convenient to play the musical instrument comfily.
Implement the present invention, effect is fine.
