Abstract
Description
Technical Field
[0001] This utility model relates to the field of guqin (a seven-stringed zither), and in particular to a modular guqin structure with easily replaceable parts. Background Technology
[0002] As one of the oldest plucked string instruments in China, the traditional guqin is complex in its production process and difficult to maintain. Especially during long-term use, vulnerable parts such as the strings, nut, bridge, and foot will suffer severe wear and tear, directly affecting the tone and lifespan of the instrument.
[0003] Currently, the maintenance of guqin mainly relies on manual repair techniques, which require professional luthiers to handle the work through tedious processes such as varnishing, filling, and re-polishing. This is not only time-consuming and labor-intensive, but also very costly, making it difficult for ordinary users to complete independently.
[0004] In performance practice, the frequent friction between the strings and the bridge and nut causes rapid wear at the contact points, and traditional structures cannot replace these parts individually; there is also a lack of effective solutions for the long-term contact wear between the goose feet and the table.
[0005] To address the aforementioned issues, this patent proposes an innovative structure that enables standardized and rapid replacement of components. While maintaining the traditional tone quality, it significantly reduces maintenance difficulty and costs, thereby enhancing the practicality and durability of the guqin. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] To achieve the above-mentioned utility model objectives, such as Figures 1-6As shown, this utility model provides a modular guqin structure with easily replaceable components, including a body 1, a headstock 2 connected to the front end of the body 1, a tailstock 3 connected to the rear end of the body 1, a dragon's beak 4 located at the middle of the rear end of the tailstock 3, two goose feet 5 threadedly connected to the lower rear side of the body 1, a tuning peg 6 connected to the lower front side of the headstock 2, a nut 7 located at the upper rear side of the headstock 2, the nut 7 consisting of a bridge, a dew-collecting structure, and string holes, multiple tuning pegs located at the lower end of the headstock 2, and multiple strings 8 positioned between the multiple tuning pegs and the two goose feet 5. The multiple strings 8 are fixedly inserted through the multiple string holes and the dragon's beak 4, and are attached to the upper end of the bridge. The multiple strings 8 are located on the upper side of the body 1. The modular guqin consists of a body 1, a headstock 2, a tailstock 3, and multiple strings 8. The strings 8 are tightly stretched between the goose feet 5 and the tuning pegs on the body 1. The guqin has a bridge at the top and passes through the chord holes (4 and 4) into the tailstock (3) and nut (7). The string (8) can be adjusted by rotating the tuning pegs to regulate the tone. During playing, the string (8) comes into direct contact with the tailstock (3) and nut (7), causing wear on the bridge (4) and the nut (7) as well as the string (8). Additionally, the goose feet (5) and tuning pegs (6) come into contact with the table, causing wear. Therefore, the guqin requires maintenance by repairing the tailstock (3), goose feet (5), tuning pegs (6), nut (7), and string (8). Modular guqins can maintain the instrument by quickly replacing the tailstock (3), goose feet (5), tuning pegs (6), nut (7), and string (8). By replacing worn parts instead of repairing them, the maintenance cost of the guqin can be reduced, and the efficiency of maintenance can be improved.
[0031] Preferably, a positioning groove 9 is provided on the rear side of the upper end of the headstock 2, and the nut 7 is engaged inside the positioning groove 9. Multiple positioning holes 10 are provided on the rear side of the lower inner wall of the positioning groove 9. Each of the cylindrical inner walls of the multiple positioning holes 10 has a limiting ring groove 11. Multiple positioning posts 12 are connected to the rear side of the lower end of the nut 7, and each positioning post 12 is inserted into the multiple positioning holes 10. Each cylindrical outer wall of the multiple positioning posts 12 is connected to a limiting ring 13, which is engaged inside the multiple limiting ring grooves 11. During the replacement of the nut 7, because the nut 7 is connected to the headstock 2 through the positioning groove 9 and is limited by the multiple positioning holes 10 and the multiple positioning posts 12, the nut 7 is effectively positioned. Furthermore, the positioning hole 10 and the positioning post 12 are limited by the limiting ring groove 11 and the limiting retaining ring 13. Therefore, when the nut 7 needs to be replaced, first remove multiple strings 8, then pull the nut 7 upwards with force, so that the limiting retaining ring 13 can be dislodged from the limiting ring groove 11 and slide out of the positioning hole 10, allowing the nut 7 to be smoothly removed from the positioning slot 9 for replacement. When installing the new nut 7 into the positioning slot 9, press the new nut 7 firmly into the positioning slot 9, and let the positioning post 12 engage with the positioning hole 10 and the limiting retaining ring 13 engage with the limiting ring groove 11 to complete the installation. This allows the nut 7 to be replaced quickly, achieving rapid maintenance of the nut 7.
[0032] Preferably, the headstock 2 has first connecting grooves 14 on both the left and right sides of its front end. Multiple first limiting side grooves 15 are connected to both ends of the two first connecting grooves 14. First connecting plates 16 are inserted into both first connecting grooves 14. The two first connecting plates 16 are respectively connected to the left and right sides of the upper end of the tuning peg 6. Multiple first limiting blocks 17 are connected to both ends of the two first connecting plates 16, and the multiple first limiting blocks 17 are respectively engaged inside the multiple first limiting side grooves 15. During the replacement of the tuning peg 6, because the tuning peg 6 is connected to the headstock 2 via the first connecting grooves 14 and the first connecting plates 16... The headstock 2 is connected and limited by the first limiting side groove 15 and the first limiting block 17. Therefore, when the peg 6 needs to be replaced, pull the peg 6 forward to make the first limiting block 17 pop out from the first limiting side groove 15 and slide out from the first connecting groove 14, so that the peg 6 can be smoothly separated from the headstock 2 for replacement. When installing the new peg 6, insert the first connecting plate 16 at the top of the new peg 6 into the first connecting groove 14 and let the first limiting block 17 snap into the first limiting side groove 15 to complete the quick replacement of the peg 6 and realize the quick maintenance of the peg 6.
[0033] Preferably, a second connecting groove 18 is provided inside the rear end of the body 1. Multiple second limiting side grooves 19 are connected to both ends of the second connecting groove 18. A second connecting plate 20 is inserted into the second connecting groove 18 and connected to the front end of the dragon gum 4. Multiple second limiting blocks 21 are connected to both ends of the second connecting plate 20, and the multiple second limiting blocks 21 are respectively engaged inside the multiple second limiting side grooves 19. During the replacement of the tailpiece 3, since the tailpiece 3 is connected to the body 1 through the second connecting groove 18 and the second connecting plate 20, and through the second connecting groove 18 and the second connecting plate 20, the tailpiece 3 is connected to the body 1 through the second connecting groove 18 and the second connecting plate 20. The second limiting side groove 19 and the second limiting block 21 limit the movement of the tailpiece. Therefore, when the tailpiece 3 needs to be replaced, pull the tailpiece 3 backward to make the second limiting block 21 pop out from the second limiting side groove 19 and slide out from the second connecting groove 18, so that the tailpiece 3 can be easily separated from the body 1 for replacement. When installing the new tailpiece 3, insert the second connecting plate 20 at the front end of the new tailpiece 3 into the second connecting groove 18 and make the second limiting block 21 snap into the second limiting side groove 19 to complete the quick replacement of the tailpiece 3 and achieve quick maintenance of the tailpiece 3.
[0034] In addition, string 8 can be replaced and maintained directly, while goose feet 5 can be replaced by unscrewing them from the bottom of the body 1, enabling quick maintenance of goose feet 5 and string 8.
[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
