36, black key, white key 52, totally 88.Fingerboard typically uses cork to make, and is rotated by bearing pin by key and is arranged on the end
On seat, and carrying out springing by finger, it is good that existing key springing sense of touch needs to carry out adjustment before dispatching from the factory, and user makes
Can not adjust the compression of key and the sense of touch of bounce-back according to the needs of oneself in.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of compression and the bounce-back adjustable fingerboard of sense of touch.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of fingerboard, it is characterised in that: comprise chassis overhang, support support, key, bearing pin, vertical pole, spring,
Travel(l)ing rest, vertical screw rod, nut, litter, helical gear, horizontal rotating shaft and handle, support support and be fixed in the middle of chassis overhang
Upside, key is rotatably provided on support support by bearing pin, has the blind hole vertically arranged on the downside of key one end,
Vertically pole is vertically arranged and vertically pole lower end is fixed on chassis overhang, and vertical pole upper end is arranged in blind hole, and litter is vertical
Arranging lower end to be fixed on chassis overhang, travel(l)ing rest is slidably arranged on litter and vertical pole and can vertically slide
Dynamic, spring housing is located at vertical screw rod upper end and spring between blind hole upper inside walls and travel(l)ing rest, and nut sleeve is located at perpendicular
Being connected with vertical screw flight on straight screw rod, nut is fixed on travel(l)ing rest, and the rotation of vertical screw rod lower end is arranged on chassis and props up
On frame and vertical screw rod lower end is connected with horizontal rotating shaft one end by helical gear, and horizontal rotating shaft is horizontally disposed with and the other end turns
Moving and be arranged on chassis overhang, handle is fixed on the end of the other end of horizontal rotating shaft.
Further, the other end of described key is provided with balancing weight, and the chassis overhang immediately below balancing weight is provided with
Soft spacer.
Further, the striped for increasing friction it is provided with outside described handle.
Further, described horizontal rotating shaft is rotated by bearing and is arranged on chassis overhang.
This utility model compared with prior art, has the following advantages and effect: fingerboard can pass through turning handle
Regulate the spacing between travel(l)ing rest and key, thus change the initial compression amount of spring, so reached to regulate key
The effect of the sense of touch of compression and bounce-back.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of fingerboard of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following example are right
Explanation of the present utility model and this utility model is not limited to following example.
As it can be seen, a kind of fingerboard of the present utility model, comprise chassis overhang 1, support support 2, key 3, bearing pin
4, vertical pole 5, spring 6, travel(l)ing rest 7, vertical screw rod 8, nut 9, litter 10, helical gear 11, horizontal rotating shaft 12 and handle 13,
Supporting support and be fixed on the upside of chassis overhang centre, key is rotatably provided on support support by bearing pin, under key 3 one end
Side has the blind hole 14 vertically arranged, and vertical pole 5 is vertically arranged and vertically pole 5 lower end is fixed on chassis overhang 1,
Vertically pole 5 upper end is arranged in blind hole 14, and litter 10 is vertically arranged lower end and is fixed on chassis overhang 1, and travel(l)ing rest 7 slides and sets
Putting on litter 10 and vertical pole 5 and can vertically slide, spring 6 is set in vertical screw rod 8 upper end and spring 6
Between blind hole 14 upper inside walls and travel(l)ing rest 7, nut 9 is set on vertical screw rod 8 threadeds with vertical screw rod 8,
Nut 9 is fixed on travel(l)ing rest 7, and the rotation of vertical screw rod 8 lower end is arranged on chassis overhang 1 and vertically screw rod 8 lower end leads to
Crossing helical gear 11 to be connected with horizontal rotating shaft 12 one end, horizontal rotating shaft 12 is horizontally disposed with and the other end rotates and is arranged on chassis overhang
On 1, handle 13 is fixed on the end of the other end of horizontal rotating shaft 12.
The other end of key 3 is provided with balancing weight 15, and the chassis overhang 1 immediately below balancing weight 15 is provided with soft spacer
16, such key 3 conveniently sets back under the effect of breeding block 15, and soft spacer 16 ensure that the soft contact of key 3 simultaneously,
Avoid sending noise and protect key simultaneously.
The striped for increasing friction it is provided with outside handle 13.Horizontal rotating shaft 12 is rotated by bearing 17 and is arranged on chassis
On support 1.Fingerboard can regulate the spacing between travel(l)ing rest and key by turning handle, thus changes spring
Initial compression amount, has so reached the effect of the sense of touch regulating the compression of key and bounce-back.
Above content described in this specification is only to this utility model example explanation.This utility model
Described specific embodiment can be made various amendment or supplements or use class by person of ordinary skill in the field
As mode substitute, without departing from the content of this utility model description or surmount model defined in the claims
