Problems solved by technology
[0002] At present, the tuners of the piano are made of brass. The strings pass through the through holes of the tuners, and the strings have an upward force on the through holes. Since the strings are made of steel, they have high hardness and small radius. The string will cut upwards on the through hole, and the brass tuner is relatively soft, so the top of the through hole will be cut and deformed, which will affect the position of the string and the tightness. Causes the strings to sound inaccurate, and the life of the tuners is short, often requiring maintenance

Embodiment Construction
[0020] The present invention will be further described below in conjunction with drawings and embodiments.
[0021] Such as figure 1 A steel core tuner shown includes a tuner head 1 and a tuner threaded part 2 connected to each other. The tuner head 1 is provided with three parallel through holes 3 through which strings 4 pass through. A steel core 5 is provided above the through hole 3 and at a position perpendicular to the through hole 3 . In order to achieve the best anti-cut effect, such as figure 2 As shown in the section, the lower part of the steel core 5 is tangent to the upper part of the through hole 3 . The diameter of the steel core is 2 mm. For the convenience of processing, the tuner head 1 and the tuner threaded part 2 are integrally formed, and the steel core 5 is one piece, which is embedded in the tuner head 1 . The material of the tuner head 1 and the tuner thread 2 is brass.
[0022] In order to connect more tightly, the position where the tuner head ...

The invention discloses a steel core chord knob comprising a chord knob head and a chord knob thread part which are mutually connected, wherein, the chord knob head is provided with a plurality of through holes, chords pass through the through holes, and a steel core is vertically arranged above the through holes. The steel core chord knob improves the existing chord knob structure, and the steel core is vertically added above the through holes; the chords pass through the through holes of the chord knob and perform a lifting acting force to the through holes; as the steel core is made of steel and has large strength so that the steel core can bear an upward cutting acting force to the through holes by the chords; and the position above the through holes is not separated to deform, thus ensuring the compactness of the chords and intonation given out by the chords, prolonging the service life of the chords and saving the time for replacement and maintenance.
Description
technical field [0001] The invention relates to a tuner for a piano, in particular to a steel core tuner. Background technique [0002] At present, the tuners of the piano are made of brass. The strings pass through the through holes of the tuners, and the strings have an upward force on the through holes. Since the strings are made of steel, they have high hardness and small radius. The string will cut upwards on the through hole, and the brass tuner is relatively soft, so the top of the through hole will be cut and deformed, which will affect the position of the string and the tightness. As a result, the strings do not sound accurate, and the tuners have a short lifespan and often require maintenance. Contents of the invention [0003] In order to overcome the disadvantages of the prior art above, the present invention provides a steel core tuner with a steel core above the through hole, which is not easy to be cut and deformed. [0004] The purpose of the present inve...
