Description
[technical field]
The present invention relates to a kind of piano finger training devices.
[background technique]
Finger practice at present in piano practice is extremely important, needs by largely practicing.It is generally used pianist
Refer to that training device is practiced.
Chinese invention patent " a kind of piano finger training device (207445475 U of Authorization Notice No. CN) " discloses one
Kind piano finger training device, the piano finger training device can be used alone, and can also be stitched together use.But the steel
Qin finger training device has following deficiency: in order to guarantee stability of the plug-in unit in slot, slot must have certain
Depth, substrate is just thicker, and the connection wall between slot and slot is just higher, and substrate is typically all injection molding, therefore mold
Manufacturing cost is high, and the connection wall between substrate lateral wall and slot and slot is easy for becoming in injection molding production process
Shape and generate defective products, cause production waste, lead to high production cost.
Therefore, the present invention is based on above deficiency and generates.
[summary of the invention]
The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a kind of structure is simple, low in cost, quality is stable
Piano finger training device.
The present invention is achieved by the following technical solutions:
A kind of piano finger training device, it is characterised in that: including support member 1, the support member 1 includes muti-piece
The support plate 11 being stacked up, every piece of support plate 11 are equipped with multiple through-holes, when the support plate 11 described in muti-piece stacks, accordingly
Through-hole connection and form key hole 2, be installed in the key hole 2 finger practice key 3.
Piano finger training device as described above, it is characterised in that: the through-hole is to pass through punching in support plate 11
The punching hole 12 cut out and formed.
Piano finger training device as described above, it is characterised in that: be provided in undermost one piece of support plate 11 with
The corresponding blind hole of through-hole above it.
Piano finger training device as described above, it is characterised in that: be connected with base in undermost one piece of support plate 11
Plate 13, the substrate 13 have smooth upper surface 13a, and finger practice 3 lower end of key is resisted against the upper of substrate 13
On the 13a of surface.
Piano finger training device as described above, it is characterised in that: the piano finger training device further includes using
Jack corresponding with key hole 2 is equipped in the box cover of the packing box 14 of the packaging support member, the packing box 14
15。
Piano finger training device as described above, it is characterised in that: the support plate 11 is plastic plate or cardboard.
Compared with prior art, the present invention has the following advantages:
1, the present invention is that through-hole is arranged in relatively thin monolithic support plate, then stacks muti-piece support plate, is stacked
Support plate just has certain thickness, and the key hole that the through-hole of corresponding connection is constituted at this time is just relatively deep, to guarantee in key hole
The stabilization of finger practice key.Due to being that through-hole is arranged in relatively thin monolithic support plate, manufacturing cost, and components are reduced
Molding, which will be got up, to be more easy, and also will be more easy to the control of element size, it is not easy to the bad feelings such as occur deforming
Condition improves the quality of product, and then reduces production cost.
2, support member of the invention is stacked up by muti-piece support plate and is constituted, and therefore, every piece of support plate is relatively thin, so branch
Through-hole on fagging easily can be punched to be formed using punching process, and moulding process is simpler, it is no longer necessary to develop plastic cement
Mold, cost are less expensive.And be that punching hole is gone out in relatively thin monolithic support plate, support plate deforms very little, components ruler
Very little stabilization, it is ensured that product quality.
3, the configuration of the present invention is simple, low in cost, quality is stablized, and is suitble to promote and apply.
[Detailed description of the invention]
Fig. 1 is 1 perspective view of the embodiment of the present invention；
Fig. 2 is the perspective view of component of the invention；
Fig. 3 is the exploded view of the component of the embodiment of the present invention 2；
Fig. 4 is the perspective view of the embodiment of the present invention 3.
[specific embodiment]
The invention will be further described below in conjunction with the accompanying drawings:
Embodiment 1:
As depicted in figs. 1 and 2, a kind of piano finger training device, including support member 1, the support member 1 include
The support plate 11 that muti-piece is stacked up, every piece of support plate 11 is equipped with multiple through-holes, when the support plate 11 described in muti-piece stacks,
Corresponding through-hole is connected to and forms key hole 2, and finger practice key 3 is installed in the key hole 2.Through-hole is arranged relatively thin
Monolithic support plate 11 on, then muti-piece support plate 11 is stacked, the support plate 11 being stacked just have certain thickness, at this time
The key hole 2 that the through-hole of corresponding connection is constituted is just relatively deep, to guarantee the stabilization of finger practice key 3 in key hole 2.Due to being
Through-hole is set in relatively thin monolithic support plate 11, and components molding, which is got up, to be more easy, the control to element size
Also it will more be easy, it is not easy to which a problem that deforming improves the quality of product, and then reduce production cost.
As shown in Figures 2 and 3, the through-hole is the punching hole 12 formed in support plate 11 by punching.It is described
Support plate 11 can be plastic plate, be also possible to the thin plate of cardboard or other materials.Since every piece of support plate 11 is relatively thin, so
Through-hole in support plate 11 easily can be punched to be formed using punching process, and moulding process is simpler, it is no longer necessary to develop
Plastic mould, cost are less expensive.And be that punching hole 12 is gone out in relatively thin monolithic support plate 11, support plate 11 deforms very
Small, element size is stablized, it is ensured that product quality.Certainly, injection molding can also be used when support plate 11 is plastic plate
Production method, since support plate 11 is relatively thin, for thicker injection molding template, the size of relatively thin support plate 11 is being molded
It is easier to control when molding, quality can be easier to be guaranteed.
Embodiment 2:
As shown in Fig. 2, embodiment 2 the difference from embodiment 1 is that:
Substrate 13 is connected in undermost one piece of support plate 11, the substrate 13 has smooth upper surface 13a, institute
Finger practice 3 lower end of key stated is resisted against on the upper surface 13a of substrate 13, it is ensured that and finger practice key 3 will not be fallen downwards,
So that finger practice key 3 connect with support member 1 it is more firm.Certainly, it also can be set in undermost one piece of support plate 11
The lower end of blind hole corresponding with the through-hole above it, such finger practice key 3 is located in the blind hole.
Embodiment 3:
As shown in figure 4, embodiment 3 the difference from embodiment 1 is that:
The piano finger training device further includes the packing box 14 for packing the support member 1, described
The box cover of packing box 14 is equipped with jack 15 corresponding with key hole 2.Support plate 11 is encapsulated in packing box 14, so that stacking
Support plate 11 be not easy to scatter.Certainly, the support plate 11 can also be connected by connection types such as bondings.
