Abstract
The invention discloses a piano part and especially relates to a clamping nail for a piano keyboard. The clamping nail comprises a plastic main body (1) and a metal sheet (2), wherein the top of the plastic main body (1) which is in contact with a base of a piano linker is wrapped by the metal sheet (2). The invention has the effects that the clamping nail for the piano keyboard provided by the invention is made of more plastic materials and few metal materials and simultaneously has the advantages of lightness and easiness in mounting of a wood clamping nail and the smooth durability for resisting the friction between a metal clamping nail and the base of the piano linker.
Description
Technical field
The present invention relates to a kind of piano parts, relate in particular to a kind of bail that is used for fingerboard.
Background technology
The bail of fingerboard is mounted in the device that the piano key tail end contacts with hammered string instrument clutch base.
There is screw thread the lower end of bail, can rotate bail to regulate the bail height.Traditional bail has two kinds of wooden and metal materials, and the upper end of wooden bail scribbles lubricant, and the upper end polishing of metal bail is to reduce the friction with the clutch base.When setting height(from bottom) is not high, generally use the metal bail, the lower end screw thread is screwed into the key lever that is equipped with the hole; When setting height(from bottom) is higher, generally use wooden bail, bail is connected card post screw mandrel after needing to join with the fore-set screw mandrel earlier again with key lever.But above-mentioned two kinds of bails have following some shortcoming:
The metal bail: weight is bigger, influences feel, and cost is higher;
Wooden bail: 1, because the bail head scribbles lubricant, rubbing behind certain number of times with the clutch base, coating can fade away, and greasy property reduces, and resistance increased when key lever was pressed, and influence is played; 2, wooden bail is a quarter sawing because of grain direction, and is loosening easily when the fore-set screw mandrel was screwed into when the hole was big, when a hole hour fore-set screw mandrel is screwed into, and easy of crack.
Summary of the invention
The object of the present invention is to provide a kind of embodiment that is used for the bail of fingerboard, it is higher shorter with serviceable life to solve the big cost of existing bail weight with expectation, and friction becomes the problem of big influence performance after use a period of time.
For addressing the above problem, the technical scheme that the present invention taked is:
A kind of bail that is used for fingerboard comprises plastic body and sheet metal, and described sheet metal wraps on the plastic body and joins the contacted top of clutch base with piano.
For making the present invention play better technique effect:
Technical scheme further is that the bottom of above-mentioned plastic body is provided with threaded hole.
Technical scheme further is that above-mentioned sheet metal can be hemispheric copper sheet.
Technical scheme further is that above-mentioned plastic body can be cylindrical.
Technical scheme further be above-mentioned sheet metal surfaceness 0.04 or below.
Adopt the beneficial effect that technique scheme produced to be: a kind of bail that is used for fingerboard of the present invention is to adopt the metal material of most plastics and fraction to process, and having possessed simultaneously has the advantage slim and graceful, that be prone to install of wooden bail to join the smooth permanance that the clutch base rubs mutually with the metal bail with piano.
Description of drawings
Fig. 1 is the structural representation of an embodiment of a kind of bail that is used for fingerboard of the present invention.
Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows an a kind of embodiment who is used for the bail of fingerboard of the present invention: a kind of bail that is used for fingerboard; Comprise plastic body 1 and sheet metal 2; Described sheet metal 2 wraps on the plastic body 1 and joins the contacted top of clutch base with piano; The present invention is a kind of like this is used for the most plastics of bail of fingerboard and the metal material of fraction is processed, and has possessed the smooth permanance that advantage and metal bail and piano couplet clutch base slim and graceful, that be prone to install that wooden bail is arranged rubs mutually simultaneously.
A kind of another embodiment that is used for the bail of fingerboard according to the present invention, the bottom of plastic body 1 is provided with threaded hole 3, a kind ofly is used for the bail of fingerboard and withstands the easy to connect and firm, stable between the screw mandrel 4 so that invent.
A kind of another embodiment that is used for the bail of fingerboard according to the present invention; Sheet metal 2 can be hemispheric copper sheet; Hemispheric sheet metal can wrap completely on the plastic body 1 and join the contacted top of clutch base with piano, and having does not waste unnecessary material, adopts copper to make sheet metal 2 simultaneously; Not only cost is low, and friction factor is also very little.
A kind of another embodiment that is used for the bail of fingerboard according to the present invention, plastic body 1 can be cylindrical.A kind of another preferred embodiment that is used for the bail of fingerboard according to the present invention, the surfaceness of sheet metal 2 0.04 or below, can keep best degree of friction.
" embodiment " who is spoken of in this manual, " another embodiment ", " embodiment ", " preferred embodiment " etc. refer to the concrete characteristic, structure or the characteristics that combine this embodiment to describe and are included among at least one embodiment of the application's generality description.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in instructions.Further, when describing a concrete characteristic, structure or characteristics in conjunction with arbitrary embodiment, what institute will advocate is that other embodiment of combination realize that this characteristic, structure or characteristics also fall within the scope of the invention.
Although invention has been described with reference to a plurality of explanatory embodiment of the present invention here; But; Should be appreciated that those skilled in the art can design a lot of other modification and embodiments, these are revised and embodiment will drop within disclosed principle scope of the application and the spirit.More particularly, in the scope of, accompanying drawing open and claim, can carry out multiple modification and improvement to the building block and/or the layout of subject combination layout in the application.Except modification that building block and/or layout are carried out with improve, to those skilled in the art, other purposes also will be tangible.
