Description

A kind of fingerboard radical occlusion device

Technical field

This utility model belongs to piano adnexa and in particular to a kind of fingerboard radical occlusion device.

Background technology

Piano abecedarian, when learning piano, is often stared at hand and is played with key, and this custom is unfavorable for cultivating player Identification of spectrogram be familiar with keyboard capability.For solving this problem, in teaching, typically blocked and drilled by teacher or another people's paper or book The sight line of the person of playing, enables student to change to bow and see the bad habit of handss, forms the good custom seeing that spectrum is played, but this mode needs Auxiliary completes on one side to stand in piano by a people, is inconvenient.

Utility model content

The purpose of this utility model is to provide a kind of fingerboard radical occlusion device of convenient use.

The technical scheme realizing the employing of this utility model purpose is as follows:

The fingerboard radical occlusion device that this utility model provides, including having the substrate of lateral length, be hinged on described base The both ends of plate and the portable plate that can fold with described substrate, the end of described substrate is provided with opens in described activity plate level The positioner positioning afterwards, the side of described substrate is provided with fixture.

The side of described substrate is provided with fixture by globe joint or sizing flexible pipe

Described positioner is the support member being actively installed in described base ends and can stretching.

Described positioner is the step being located at described base ends.

Beneficial effect

This utility model can be fixed on the music stand of upright piano by fixture when using, and portable plate is opened, and utilizes The sight line of piano abecedarian is blocked by substrate and portable plate, changes student and bows and see the bad habit of handss to reach, forms and see spectrum The good custom played.This utility model adopts fixture, easy to installation and removal, and portable plate adopts folding mode, is easy to carry, because This has the advantages that easy to use.

Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings.

Brief description

Fig. 1 is structural representation of the present utility model.

Fig. 2 is schematic diagram when portable plate of the present utility model draws in.

Fig. 3 is the top view of Fig. 2.

Fig. 4 is use state schematic diagram of the present utility model.

Specific embodiment

See Fig. 1 Fig. 3, the fingerboard radical occlusion device that this utility model provides, including the substrate 1 with lateral length, At the both ends of described substrate 1, the portable plate 6 that can fold with described substrate 1, the end of described substrate 1 are hinged with by hinge 5 Portion is provided with the positioner of positioning after described portable plate 6 level is opened, and described positioner is to be actively installed on described edge of substrate In portion and the support member 2 that can stretch, the side of described substrate 1 passes through globe joint or sizing flexible pipe 4 is provided with fixture 3.

Described positioner may also be employed being located at the step 7 of described substrate 1 end.

As shown in figure 4, when player uses this utility model, first the music stand b on upright piano a qin lid d being opened, passing through This utility model is fixed on the music stand b of upright piano fixture 3, adjusts the upper of substrate using globe joint or sizing flexible pipe 4 Lower angle, extracts out from the support member 2 at substrate 1 both ends, then portable plate 6 is opened to both sides one-tenth is horizontal, using supporting part Part 2 positions (if positioner adopts step 7, directly being positioned with step 7), and substrate 1 and portable plate 6 can regarding player Line blocks so as to can't see keyboard c.
