Description
Technical Field
[0001] This utility model relates to the field of guzheng string threading technology, and more specifically, to a guzheng string threading aid. Background Technology
[0002] The guzheng, a shining pearl in the treasure trove of traditional Chinese music, boasts a history of over two thousand years and is an extremely important plucked string instrument in Han culture. Its elegant shape and unique timbre earned it the reputation of "the head of string and bamboo instruments" in ancient times. The guzheng has an intricate structure, typically composed of a soundbox, soundboard, bridge, and strings. The strings play a crucial role in the expression of tone. Originally made of silk, they gradually evolved to nylon or metal, which not only increased durability but also made the tone brighter and more sustained. During performance, the player lightly plucks the strings with their fingertips, using techniques such as glissando and vibrato to create a rich and varied sound, expressing both passionate emotions and delicate sentiments, transporting the listener to a musical world full of poetry and imagination.
[0003] Stringing the guzheng is a process that requires both skill and caution, and is crucial for the maintenance and adjustment of the instrument. Stringing refers to correctly installing the strings onto the guzheng and adjusting them to the appropriate tension and pitch. Because guzheng strings are mostly made of nylon or metal wire, these materials are relatively soft when not fully taut, but become very hard and sharp when stretched, especially on new or recently adjusted strings, where the edges can be exceptionally sharp. Therefore, when stringing, players can easily injure their fingers due to carelessness, especially when frequently adjusting string tension or changing strings.
[0004] How to design a string-threading aid for the guzheng to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

A pusher plate 7 is fixedly connected to the end of the sleeve 6. A string groove 8 is provided on the inner side of the pusher plate 7. A fitting hole 60 is provided at the end of the sleeve 6. The fitting hole 60 fits into the end of the string pin 5. A snap-fit groove is provided at the end of the sleeve 6 away from the pusher plate 7. A wrench assembly is provided on one side of the sleeve 6. A nail hole is provided through the string pin 5. The string 3 passes through the nail hole and the string pin 5. One end of the string pin 5 is externally threaded, and the other end is square. The string pin 5 is connected to the soundboard 1 through its external thread.
[0024] The wrench assembly includes a wrench head 9 and a handle 10. The wrench head 9 is hollow, and a rotating rod 11 and a rotating shaft 13 are rotatably connected inside the wrench head 9. The rotating shaft 13 is located above the rotating rod 11. A gear 12 is fixedly sleeved on the outer wall of the rotating rod 11. A conversion element 14 is provided on the rotating shaft 13. The conversion element 14 has two vertices 15 and two arc openings 16. One of the vertices 15 is engaged with the gear 12. A ball groove is opened on the inner side wall of the wrench head 9. A push ball 17 and a push spring 18 are provided inside the ball groove. The push ball 17 and the push spring 18 are fixedly connected. A paddle 19 is provided at the end of the rotating shaft 13.

[0025] The working principle of this guzheng string-threading aid is as follows: First, the string 3 is threaded into the string hole 4 on the string-threading plate 2. Then, the string 3 is threaded into the nail hole on the string pin 5. By aligning the string groove 8 on the push plate 7 with the end of the string 3 passing through the string pin 5, the sleeve 6 is pushed, causing the end of the string pin 5 to enter the sleeve 6. At this time, the push plate 7 presses against the string 3, causing the string 3 to enter the string groove 8, changing the end of the string 3 from a perpendicular state to a parallel state. The sleeve 6 is then engaged with the wrench assembly. By rotating the handle 10, the sleeve 6 is rotated, which in turn rotates the string pin 5, causing the string 3 to be wound around the surface of the string pin 5. At the same time, the section of the string 3 parallel to the string pin 5 is pressed down, thereby fixing the position of the string 3 and completing the installation of the string 3. This process first fixes the string 3 through the string groove 8 on the string pusher plate 7, and then rotates the string pin 5 to tighten the string 3. Compared with the existing technology, which first winds the string 3 around the string pin 5 and then rotates the string pin 5, this is more convenient and also prevents the problem of the string 3 easily pricking the fingers when it is wound around the string pin 5.
