Abstract
A grand piano tuning knob comprises an upper cylinder (4), a flat column body (1) arranged on the upper end surface of the upper cylinder (4) and a lower screw (5) arranged on the lower end surface ofthe upper cylinder (4), wherein the upper cylinder (4), the flat column body (1) and the lower screw (5) form an integral structure, at least one tuning through hole (3) is arranged on the flat column body (1), a hole (2) whose axial cord is vertical to the axial cord of the tuning through hole (3) is arranged on the flat column body (1), the bottom of the hole (2) is communicated with the top portion of the tuning through hole (3), and a steel wire (9) is tightly matched in the hole (2). Compared with the prior art, since the top portion of the through hole for pressing a string originally in the tuning through hole is changed into the condition that the existing steel wire is contacted with the string to play a role of pressing the string, the strength of the steel wire is far better than the turning knob, thereby the steel wire can not be damaged easily under the effect of string tension, the depth of pressing the string can be guaranteed, and the pitch accuracy stability of the piano is better.
Description
Technical field:
The utility model belongs to the Piano Fittings field, particularly relates to a kind of grand piano button of tuning up.
Background technology:
The grand piano of the prior art button of tuning up comprises flat cylinder, upper cylinder and bottom screw rod, flat cylinder is located at the upper surface (flat cylinder also can be regarded as the projection of the flat cylinder shape in upper surface that is upper cylinder) of upper cylinder, the bottom screw rod is located at the lower surface of upper cylinder, the three is an integral structure, flat cylinder is provided with the through hole of tuning up, and the two ends of the through hole of tuning up are hydraucone.When being assembled on the piano, string passes the through hole of tuning up, the peak of through hole of tuning up this moment plays the effect of pressing string, but because string has certain force of strain, it is fragile that the peak of through hole of tuning up during use is subjected to the pressure of string, therefore be difficult to guarantee the depth of string pressure string, this has just caused the accuracy in pitch less stable of piano.
The utility model content:
The technical problems to be solved in the utility model provides a kind of accuracy in pitch stability that string presses the depth of string and piano grand piano button of tuning up preferably that guarantees.
The utility model overcomes the above problems used technical scheme: a kind of grand piano with following structure button of tuning up is provided, it comprises upper cylinder, be located at the flat cylinder and the bottom screw rod that is located at the upper cylinder lower surface of upper cylinder upper surface, described upper cylinder, flat cylinder and bottom screw rod are integral structure, described flat cylinder is provided with at least one through hole of tuning up, described flat cylinder is provided with the central axis hole vertical with the central axis of the through hole of tuning up, the bottom in described hole all communicates with the top of the through hole of tuning up, and wringing fit has steel wire in the described hole.
After adopting above structure, the utility model compared with prior art, because flat cylinder is provided with the central axis hole vertical with the central axis of the through hole of tuning up, the bottom in hole all communicates with the top of the through hole of tuning up, and wringing fit has steel wire in the hole, when then being assemblied on the piano, through hole Central Plains of tuning up is used to press the top of the through hole of string to become present steel wire to contact the string effect of pressing of playing with string, the toughness of steel wire will be much better than the button of tuning up, so it is not fragile under the effect of string tension force, can guarantee the depth of string pressure string, thereby make that the accuracy in pitch stability of piano is better.
As improvement, the junction of the lower surface of described upper cylinder and bottom screw rod is provided with the axial notch of ring-type, the crude problem that the button of tuning up is tilted that then can avoid iron plate to occur because of punching, make the lower surface and the iron plate of upper cylinder fit tightly, further guarantee the accuracy in pitch stability of piano.

As shown in the figure: 1, flat cylinder, 2, the hole, 3, the through hole of tuning up, 4, upper cylinder, 5 bottom screw rods, 6, iron plate, 7, string, 8, capotasto, 9, steel wire.
Embodiment:
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described further, but the utility model is not limited only to following concrete embodiment:
As Fig. 1, Fig. 2, Fig. 3 and a kind of grand piano shown in Figure 4 button of tuning up, it comprises upper cylinder 4, be located at the flat cylinder 1 and the bottom screw rod 5 that is located at upper cylinder 4 lower surfaces of upper cylinder 4 upper surfaces, described upper cylinder 4, flat cylinder 1 and bottom screw rod 5 are integral structure, described flat cylinder 1 is provided with at least one through hole 3 of tuning up, the difference of through hole 3 of tuning up according to the range of sound that is provided with, be provided with a (see figure 1), two (see figure 2)s or three (see figure 3)s, described flat cylinder 1 is provided with the central axis hole 2 vertical with the central axis of the through hole 3 of tuning up, the bottom in described hole 2 all communicates with the top of the through hole 3 of tuning up, be meant that specifically the through hole 3 of tuning up is no matter be one or two or three, its top all communicates with the bottom in hole 2, wringing fit has steel wire 9 in the described hole 2, and the effect of pressing string is played at the top that steel wire 9 is used for replacing tuning up originally in through hole 3 holes.
The lower surface of described upper cylinder 4 is provided with annular recess, the center of circle of described annular recess correspondence is on the axis of bottom screw rod 5, the interior circular diameter of annular recess is not more than the diameter of bottom screw rod 5, the problem that the button of tuning up that the burr that annular groove is used for avoiding iron plate 6 to occur because of punching causes tilts when installing, thus the accuracy in pitch of piano guaranteed.
The bottom in described hole 2 communicates with the top of the through hole 3 of tuning up and is meant, after in hole 2, being furnished with steel wire 9, steel wire 9 bottoms and the vertical range between through hole 3 bottoms of tuning up are not less than the diameter of string 7, because when vertical range during greater than the diameter of string 7, string 7 can't pass the through hole 3 of tuning up; When vertical range equaled string 7, string 7 just can pass the through hole 3 of tuning up, and then because of the effect of capotasto 8, an effect of the power that makes progress is arranged at the bottom of 7 pairs of steel wires 9 of string in the through hole 3 of tuning up; When vertical range during less than string 7, because of the effect of capotasto 8, string 7 still can have an effect of the power that makes progress to the bottom of steel wire 9 in the through hole 3 of tuning up equally.Therefore steel wire 9 has replaced tuning up originally through hole 3 tops as the effect of pressing string.
Add man-hour, job operation is conventional method, and the thickness of flat cylinder 1 is advisable with the tension force that can support string 7, and the top of the bottom in hole 2 and the through hole 3 of the tuning up degree of intersecting simultaneously can be passed string 7 behind the steel wire 9 and is advisable to be loaded onto in the hole 2.
During use, by bottom screw rod 5 the utility model is fixed in the threaded hole corresponding on the iron plate 6, end with each string 7 is fixed on the iron plate 6 by common mode again, pass the through hole of the other end of each string 7 from each self-corresponding flat cylinder 1, capotasto 8 through projection on the iron plate 6, capotasto 8 plays the effect of supporting string, is fixed at last on each self-corresponding Tuning peg pin.
