The purpose of this utility model is the defect more difficult in order to solve the training of the hand-type of abecedarian in prior art, it is provided that Yi Zhongshi For abecedarian and there is the piano of illumination functions to solve the problems referred to above.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of abecedarian of being applicable to and there is the piano of illumination functions, including keyboard with for correcting the apparatus for correcting of hand-type function； Described keyboard is fixed on keyboard drawer；Described apparatus for correcting is fixed on described keyboard drawer；Described apparatus for correcting includes one Pressure pin；Rotated by location bar respectively at the two ends of described pressure pin and be fixed on described keyboard drawer；Described apparatus for correcting also wraps Include pole；One end of described pole rotates and is fixed on described keyboard drawer；The other end of described pole is free end；Institute State position corresponding with described pole on pressure pin and be provided with the hole accommodating strut ends；The free end of described pole inserts described hole Hole, makes described pressure pin be in a fixed position；Described keyboard drawer is further fixed on cover of keyboard；Described cover of keyboard and described key The side that dish is relative offers multiple hole, is respectively and fixedly provided with LED in multiple holes；It is provided with in the lid of described cover of keyboard and institute State the passage that multiple hole is identical；Described LED is electrically connected with the power supply by described passage.

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.

Preferably, described location bar is fixed with described supporting plate by rotating shaft；Described rotating shaft is parallel with described pressure pin.

Preferably, one end of described pole rotates the edge of the close human body side being fixed on described supporting plate.

Preferably, the side of the good person of modern times's body of described supporting plate is provided with the receiving chamber accommodating described pole.

Preferably, described pressure pin and wrist contact surface are cambered surface.

Preferably, described pressure pin is cylindrical.

Preferably, when described cover of keyboard is opened, the afterbody of described LED is higher than its front end；The light of described LED shines Penetrate on said keyboard.

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；

By rotating shaft, when not practicing qin, pressure pin can be turned to the lower section of backing, be not take up space, be the outward appearance of piano More good-looking；

The upper surface of pressure pin cambered surface, it is to avoid have sharp corner angle to fray the tender and lovely skin of child；

By arranging multiple LED on cover of keyboard, even if not opening indoor illumination, LED can provide enough lights, Seeing keyboard clearly for piano practicer, LED is more environmentally friendly energy-conservation, and it is more beautiful to practice qin artistic conception.

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:

A kind of abecedarian of being applicable to and there is the piano of illumination functions, including keyboard 1 with for correcting hands The apparatus for correcting 2 of type function；Keyboard 1 is fixed on keyboard drawer 3；Apparatus for correcting 2 is fixed on keyboard drawer 3；Correct Device 2 includes a pressure pin 21, location bar 22 and pole 23；It is fixed on keyboard by location bar 22 at the two ends of pressure pin 21 On bracket 3.One end of pole 23 rotates and is fixed on keyboard drawer 3, and the other end is free end.Pressure pin 21 and pole 23 Corresponding position is provided with the hole accommodating pole 23 free end.When practicing qin, pressure pin 21 is turned to appropriate location, make to prop up The free end of bar 23 inserts in hole, makes pressure pin 21 stable at certain altitude, and when this height is for practicing qin, normal wrist is high Degree position.Keyboard drawer 3 is further fixed on cover of keyboard 4；The side that cover of keyboard 4 is relative with keyboard 1 offers multiple hole, Multiple LED 41 it is fixed with in multiple holes；It is provided with the passage identical with multiple holes in the lid of cover of keyboard 4 (figure not to show Go out)；Multiple LED 41 are electrically connected with the power supply by passage.

In order to make the light of LED 4 be radiated on keyboard, this utility model will be configured with necessarily when the hole on cover of keyboard 4 Angle, when i.e. cover of keyboard 4 is opened, the afterbody of LED is higher than its front end, so that the light-illuminating of LED 41 is at keyboard On 1.

Wherein, multiple LED 41 uniformly divide half bookshelf 42 both sides on cover of keyboard 4, to avoid being lived light by bookend.

As it is shown on figure 3, keyboard drawer 3 includes the supporting plate 31 of both sides and the backing 32 of bottom；Location bar 22 is by rotating shaft 24 Being fixed on supporting plate 31, rotating shaft 24 is parallel with pressure pin 21.

Pole 23 rotates and is fixed on supporting plate pressure pin 21 higher than backing 32 near the side of human body, and at backing 32 near human body Side also sets up a receiving chamber 231 accommodating pole 23.When without qin, pole 23 is taken in receiving chamber 231, make The outward appearance of piano is more attractive.

In order to reduce pressure and the frictional force of wrist, pressure pin 21 and wrist contact surface are cambered surface by this utility model, or directly Pressure pin 21 for circular cross-section.The diameter of pressure pin 21 or width should not be the widest, and about 5～10cm.The upper table of cambered surface Face, it is to avoid have sharp corner angle to fray the tender and lovely skin of child.

The pressure pin 21 that this utility model provides, when being propped by pole 32, is exactly in below wrist when abecedarian plays the piano, The wrist making abecedarian is in normal level, it is simple to abecedarian keeps correct posture and hand-type at the moment when playing the musical instrument.

Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.The industry Skilled person will appreciate that, this utility model is not restricted to the described embodiments, described in above-described embodiment and description only Being principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has various change Changing and improve, these changes and improvements both fall within the range of claimed this utility model.The guarantor that this utility model requires Scope of protecting is defined by appending claims and equivalent thereof.
