Embodiment 1

[0015] Embodiment 1, as figure 1 , figure 2 As shown, an anti-running string mechanical shaft is composed of a damping structure and a locking mechanism. Through the damping mechanism and locking mechanism arranged on the left and right plates of the string groove. The damping mechanism is arranged on the left plate (10) of the string groove of the musical instrument, and the damping mechanism is composed of a damping plate (3), a spring seat (2), a tuner sealing plate (4), and a tuner shell (5). The damping mechanism uses elastic force to press the damping plate (3) to meet the large frictional force required for tuning. The annular spring seat (2) is provided with a spring (9). The damping mechanism is made of metal and anti-aging and wear-resistant The assembly composed of materials is not affected by the change of weather temperature and humidity. The tuner shell (5) is arranged outside the damping plate (3), and the tuner shell (5) is fixed on the left plate (10) of th...

Embodiment 2

[0016] Embodiment 2, as image 3 As shown, when installing in reverse, the spring seat (2) is welded on the damping mechanism as the tuner sealing plate (4), and the spring seat (2) is welded on the tuner shell (5), and the working principle is the same. The damping mechanism uses the elastic force of the spring (9) to press the damping plate (3). Since the damping plate (3) is made of anti-aging and wear-resistant materials, the friction force required for tuning can be satisfied when the spring pressure is large. When turning the peg (1) to make the strings reach the standard pitch, you can tighten the locking screw (7). During the tightening process, the locking chuck (8) is squeezed, and the locking chuck (8) also has a taper, and the taper is the same as that of the locking screw (7), and the locking chuck (8) has a cross-shaped groove, so that The locking chuck (8) holds the peg (1) tightly, so as to achieve the purpose of locking. The piano shaft can be loosened by th...

Abstract

A string offset preventing mechanical axis is provided, belongs to the technical field of musical instrument, and particularly relates to a string offset preventing mechanical axis applied for string musical instruments such as lute, plucked stringed musical instrument, Nguyen violin, cello, viola and violin. The string offset preventing mechanical axis is composed of a damping structure and a locking mechanism. The damping structure and the locking mechanism are respectively arranged on a left plate and a right plate of a string slot of the musical instrument; the string axis of the musical instrument runs through the damping structure and the locking mechanism located on the left and right plates of the string slot successively. The string offset preventing mechanical axis provided by the invention has the following beneficial effects: the string offset preventing mechanical axis is made of metal which is free from the effects of weather, temperature and humidity; in this way, the strings are easy to adjust and the string offset phenomenon during playing is avoided, the string axis is locked fixedly in order to avoid the string offset. The string offset preventing mechanical axis is featured in simple structure, low manufacturing cost and wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of musical instruments, and relates to an anti-running string mechanical shaft used for string instruments such as pipa, liuqin, ruan, large, medium and violin. Background technique [0002] At present, the shafts of pipa, liuqin, big, medium and violin are basically wooden shafts. Due to the lack of precision in the manufacturing process, or the influence of weather, temperature and humidity, the peg hole and peg size will change. However, using wooden shafts If it does not move or is not tightened tightly or is too loose after tightening, the friction between the peg and the peg hole will be uneven and unstable, resulting in difficulty in tuning. The depth is difficult to grasp, which brings a lot of trouble for beginners to practice. If professionals suddenly run out of strings during performance, it will be a big disaster. At present, in the face of these situations, people paint chalk on the pegs if the...
