Description

Technical Field

[0001] This utility model belongs to the field of guzheng string changing auxiliary technology, specifically relating to a guzheng string changing auxiliary perforation device. Background Technology

[0002] The zither, also known as the Han zither, Qin zither, Yao zither, and Luan zither, is a traditional Chinese musical instrument belonging to the plucked string instrument family. Because the strings of the zither are frequently plucked by the user, they often become damaged and need to be replaced due to long-term wear and tear.

[0003] Patent CN222720066U describes a string-changing auxiliary perforation device for a guzheng (Chinese zither). The suspension wire inside the inner groove can be pulled out. When changing an old string, the suspension wire is connected to the old string, and when the old string is pulled out, it can be passed through the hole. Then, the new string is connected, and the new string can be pulled into the hole through the suspension wire, thus achieving the effect of convenient string changing. However, the suspension wire is also a soft wire, which is easily deformed under stress when perforating, making it difficult to perforate. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a string changing auxiliary hole device for guzheng, which has the advantage of facilitating string threading.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a string changing auxiliary perforation device for a guzheng (Chinese zither), comprising a needle, a tail tube fixedly connected to the outer wall of the tail of the needle, a groove formed on the outer wall of the middle part of the tail tube, multiple slots formed on the outer walls of both sides of the tail tube, and a round head provided at the front end of the needle.

[0006] The above technical solution facilitates stringing. The unpacked string is inserted into the slot 3, and then the string is wound in an S-shape into the slot 4. This fixes the string to the tailpiece 2. The string can then be threaded through the string hole of the guzheng by the needle 1. The round head 5 prevents the needle 1 from damaging the surface of the guzheng.

[0007] Preferably, the card slot includes a friction groove, and the top outer wall of the friction groove has a horn groove communicating with the groove.

[0008] The above technical solution can facilitate insertion. The opening of the horn groove 401 allows the string to be inserted from the slot 3 into the friction groove 400. It also makes it easy to remove the string from the horn groove 401 during subsequent disassembly.

[0009] Preferably, the friction groove is an oblong groove, wider on both sides and narrower at the top and bottom.

[0010] The above technical solution can facilitate the fixing of the strings. When the strings enter the friction groove 400, the strings will sink to the bottom, and the narrow sides can limit the position of the strings.

[0011] Preferably, the horn groove is X-shaped, with large openings at the top and bottom and a narrow middle section.

[0012] The above technical solution facilitates stringing, and the large openings at the top and bottom guide the movement of the strings, making it easier to insert them.

[0013] Preferably, the length of the needle is 10cm.

[0014] The above technical solution facilitates insertion. Since the thread hole at the tail of the guzheng is deep, the needle 1 has a length of 10cm, which can be conveniently used to insert the thread.

[0015] Preferably, the tail tube is 5cm long and the slot is wider than 2.5mm.

[0016] The above technical solution makes it easy to fix the strings. The tail tube is 5cm long and can have more slots 4, which can ensure that the strings are provided with sufficient friction.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Insert the opened strings into the slot, and then wrap the strings in an S-shape around the slot to fix the strings to the tailpiece. Then, you can thread the strings through the string holes of the guzheng by threading a needle. The rounded end of the needle can prevent damage to the soundboard of the guzheng.

[0019] 2. The opening of the trumpet groove allows the string to be inserted into the friction groove from the opening. It also makes it easy to remove the string from the trumpet groove when disassembling later. When the string enters the friction groove, the string will sink to the bottom. The narrow sides can limit the movement of the string, while the large openings at the top and bottom can guide the movement of the string, making it easy for the string to be inserted.
