Fine tuning peg for huqin-class musical instrument

Abstract

The present invention provides a fine tuning peg for a huqin-class musical instrument. A planet decelerator is arranged at the rear portion of a hollow peg body, an input shaft of the planet decelerator is connected with a rotary knob of the rear end of the peg body, a winding tuning peg is arranged in the peg body, an output shaft of the planet decelerator is connected with one end of the windingtuning peg, the other end of the winding tuning peg is extended out of the peg body, the portion of the winding tuning peg extending out of the peg body is sleeved with a string hanging device, a string passing hole is arranged at the portion of the winding tuning peg extending out of the peg body, the string hanging device is provided with a pair of through holes, and a hollow pin penetrates thestring passing hole and the pair of through holes. The hollow pin passes through the winding tuning peg and the string hanging device to reliably fix the string hanging device on the winding tuning peg. The fine tuning peg is arranged on the huqin body in a penetrating mode, after the qin strings pass through the hollow pin, the fine tuning peg can be the same as a traditional qin peg to achieverapid rough tuning through manual operation of the peg body, the fine tuning peg rotates the rotary knob to achieve fine rotation of the winding tuning peg by transmission of the winding tuning peg through the planet decelerator, and therefore, fine tuning of the qin strings can be achieved.

Description

technical field [0001] The invention relates to a piano shaft for tensioning strings, in particular to a fine-tuning peg for huqin instruments. Background technique [0002] The strings on some huqin instruments (such as Erhu, Jinghu) and plucked instruments (such as pipa) are all tightened and adjusted by pegs. The existing traditional pegs are completely adjusted by hand feeling in use. The disadvantage is that it is very inconvenient and difficult to control when fine-tuning the tightness of the strings to achieve tuning. The basic structure of a peg disclosed in the Chinese patent is as follows: a planetary reducer is installed at the rear of a hollow shaft, the input shaft of the planetary reducer is connected with the knob at the rear end of the shaft, and the peg is installed in the shaft, and the planetary deceleration The output shaft of the device is connected with one end of the winding shaft, and the other end of the winding shaft protrudes from the shaft body. ...

AI Technical Summary

Problems solved by technology

The peg can fine-tune the strings, but there is a shortcoming: when the string hanger is installed on the peg, the through hole must be aligned with the string hole first, and then the screw is tightened, which is troublesome to install; in use, The screws are easy to loosen, which will cause the string hanger to loosen and affect the intonation; the string hanger needs to be processed with threaded holes for mounting screws, which increases the preparation cost
