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 2mm. 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 1...

Abstract

The invention discloses a steel core tuner, which comprises a tuner head and a tuner threaded part which are connected to each other. The tuner head is provided with several through holes through which strings pass. Above the through holes, A steel core is provided at a position perpendicular to the through hole. This steel core tuner improves the structure of the existing tuner. A steel core is added above the through hole and perpendicular to the through hole. The strings pass through the through hole of the tuner, and the strings are aligned with the through hole. There is an upward pulling force. Since the steel core is made of steel material with high hardness, it can withstand the upward cutting force of the strings on the through hole. Therefore, the upper part of the through hole will not be cut and deformed. It ensures the tightness of the strings and the pitch of the strings, and the life of the tuners is long, 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...
