Abstract
The utility model relates to a piano action adjusting knob screw. The piano action adjusting knob screw comprises an adjusting thread part and an adjusting handle fixedly arranged on the top of the adjusting thread part, wherein the adjusting handle is tabular; the adjusting thread part is externally provided with threads completely; the adjusting part is flat in shape; sharp-nose pliers can be used for screwing the knob easily; and clearances among screws of a slim action adjusting knob become large without mutual affection to respective action adjusting knob screw in operation.
Description
[technical field]
The utility model relates to piano technical field, is specifically related to a kind of piano striking machine adjusting knob screw.
[background technology]
Piano striking machine adjusting knob screw adjustment part circle of position shape in the market, thumb screw structure, so must ensure the internal diameter in round end hole because needs regulate, because piano striking machine structure is intensive, 88 combinations are arranged together closely, when being regulated, each hammered string instrument adjusting knob screw is easy to each other influence each other, too compact hammered string instrument adjusting knob screw regulates and wastes time and energy, between adjacent due to adjusting knob in the time adjusting and install, position is very compact, easily cause the bad adjustment of part adjusting knob, even influence each other.
[utility model content]
The purpose of this utility model is to overcome the defect of prior art, provides a kind of volume little maneuverable piano striking machine adjusting knob screw.
For achieving the above object, technical solution adopted in the utility model is:
A kind of piano striking machine adjusting knob screw, it comprises the adjusting handle that regulates threaded portion and be fixedly installed on adjusting top, threaded portion, and described adjusting handle is flat, and outside, described adjusting threaded portion is all provided with screw thread.
Furtherly, the width of described adjusting handle is 0.8-1.5 with the ratio range that regulates threaded portion diameter.
Furtherly, described adjusting handle is rounded square.
Furtherly, described adjusting threaded portion and adjusting handle are one-body molded, and the material of described adjusting threaded portion and adjusting handle is No. 45 steel.
Compared with prior art, the beneficial effect that the utility model is obtained is:
Adjusting portion shaped flat of the present utility model, is used nose pliers knob easily, and it is large that the hammered string instrument adjusting knob screw gap between them of weight reducing becomes, and in the time that the hammered string instrument adjusting knob screw on separately operates, do not affect each other.
[brief description of the drawings]
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side structure schematic diagram;
Fig. 3 is background technology structural representation;
In the accompanying drawings: 1 adjusting handle, 2 regulates threaded portion.
[embodiment]
Below in conjunction with attached Fig. 1 and 2, the utility model is described in more detail.
As shown in attached Fig. 1 and 2, a kind of piano striking machine adjusting knob screw, comprise and regulate threaded portion 2 and be fixedly installed on the adjusting handle 1 that regulates 2 tops, threaded portion, described adjusting handle 1 is flat, 2 outsides, described adjusting threaded portion are all provided with screw thread, and the width of described adjusting handle 1 is 0.8-1.5 with the ratio range that regulates threaded portion 2 diameters.As shown in Figure 2, described adjusting handle 1 is rounded square, and described adjusting threaded portion 2 and adjusting handle 1 are one-body molded, and the material of described adjusting threaded portion 2 and adjusting handle 1 is No. 45 steel.
Piano striking machine adjusting knob screw adjustment part circle of position shape in the market, as shown in Figure 3, thumb screw structure, so must ensure the internal diameter in round end hole because needs regulate, because piano striking machine structure is intensive, 88 combinations are arranged together closely, when being regulated, each hammered string instrument adjusting knob screw is easy to each other influence each other, adjusting portion 1 shaped flat of utility model, use nose pliers knob easily, it is large that the hammered string instrument adjusting knob screw gap between them of weight reducing becomes, in the time that operating, the hammered string instrument adjusting knob screw on separately do not affect each other, the hammered string instrument adjusting knob screw of weight reducing does not reduce the turning moment of hammered string instrument adjusting knob screw, increase on the contrary hammered string instrument adjusting knob screw turn-knob moment, make the adjusting of hammered string instrument adjusting knob screw easier, the Torque-adjusting of original hammered string instrument adjusting knob screw is the radius of interior ring, the radius of interior ring is significantly less than the radius that regulates threaded portion 2, adjusting portion 1 after improvement makes the knob moment of hammered string instrument adjusting knob screw between 0.8-1.5 times that regulates threaded portion 2 radiuses.
Other structures of the piano that the utility model relates to and ordinary steel lyrate with, do not relate to annexation between the modular construction of the technical program and parts and do not repeat.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the present invention.For persons skilled in the art, any apparent change of under the prerequisite that does not deviate from the utility model principle and spirit, it having been done, within all should being contemplated as falling with claim protection domain of the present utility model.
