Technical Field

[0001] The utility model belongs to the technical field related to guqin, and specifically relates to a spiral adjustment type peg. Background Art

[0002] Guqin is one of the oldest and most important traditional Chinese musical instruments, with a long history and rich cultural connotations. Qinzhen refers to a structure on the guqin used to fix the strings and adjust the pitch. Qinzhen is usually made of wood and installed on the head part of the guqin. The strings pass through the holes of the Qinzhen. The tension of the strings can be changed by adjusting the position of the Qinzhen, thereby adjusting the pitch of the strings. At the same time, the performer can also use the small holes on the Qinzhen to perform special playing techniques, such as glissando, vibrato, etc., which is an indispensable part of guqin performance.

[0003] However, the traditional method of adjusting the pegs is usually to fix the pegs and the strings and adjust the tightness of the strings by twisting the ropes. This method often causes slippage during adjustment, causing the strings to rebound, and it is impossible to stably adjust the tightness of the strings. Utility Model Content

[0004] The purpose of the utility model is to provide a spiral-adjustable peg to solve the problem that the traditional peg adjustment method proposed in the above background technology usually fixes the peg and the string by twisting the rope and adjusts the tightness of the string. This method usually causes slippage during adjustment, causing the string to rebound, and the problem of being unable to stably adjust the tightness of the string.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spiral adjustment type peg, comprising a peg and an outlet arranged at the bottom of the peg;

[0015] Compared with the prior art, the utility model provides a spiral adjustment type peg, which has the following beneficial effects:

[0016] 1. By using the structure of an internal threaded sleeve, a threaded block and an internal insert rod, more precise string adjustment can be achieved. The threaded connection can provide finer adjustment steps, making the adjustment process more accurate and the tightness and pitch of the strings better controlled. Using an anti-slip pad as the contact surface at the bottom of the tail can increase the friction between the pegs and the tail, preventing the pegs from sliding or slipping during the adjustment process, thereby ensuring the stability and accuracy of the adjustment. By rotating the pegs, the tightness and position of the strings can be gradually adjusted. This adjustment method is more convenient and quicker than the traditional rope twisting method, and can more easily adjust the pitch and timbre of the strings. This peg structure has advantages in accuracy, stability, convenience and timbre control in guqin tuning, which can improve the performer's control over the guqin's timbre and simplify the tuning process.

[0017] 2. By arranging an upper threaded head, an upper threaded sleeve, an external threaded sleeve, a fixing metal sheet, a fixing bolt, a transverse bolt and a nut, it is possible to achieve a firm fixation of the tether and the rope sleeve. The external threaded sleeve is fixed to the tether by the fixing metal sheet, and is tightened by the fixing bolt and the transverse bolt to ensure that the external threaded sleeve will not move during the tuning process, thereby ensuring the stability and accuracy of the tuning. The fixing metal sheet provides a fixing point, which makes the connection between the external threaded sleeve and the tether more secure and avoids the possibility of loosening or falling off. By rotating the upper threaded head, the upper rope sleeve can be gradually tightened and fastened to the chord node, thereby ensuring that the rope sleeve and the chord node are more firmly fixed, and preventing the rope sleeve from being too large and causing the chord node to detach from the rope sleeve, thereby affecting the performance quality of the guqin. The improved structure has the advantages of stability, enhanced fixing effect and stable chord node fixation in terms of tuning of the pegs, which can improve the stability and accuracy of the tuning, while ensuring a firm connection between the chord node and the rope sleeve, thereby improving the performance quality of the guqin.
