Description

Technical Field

[0001] The utility model relates to the technical field of konghou, in particular to a flexible tuning device for a modern konghou. Background Technique

[0002] The konghou, also known as Kanhou or Konghou, is a traditional plucked string instrument in ancient China and also a kind of plucked instrument. The konghou has a history of more than two thousand years. From ancient times to the Tang Dynasty, its playing art continued to develop and reached a relatively high level. However, since the late 14th century, the konghou has no longer been popular and has gradually disappeared. Only partial patterns can be seen on the remaining murals and reliefs. The modern Chinese konghou is a new instrument innovated by Chinese musical instrument reformers since the 1970s on the basis of the sketches of the large konghou left in the Qingyue Canon, combining the characteristics of instruments such as the harp and the zheng. The new konghou is different from the ancient konghou in terms of appearance, structure and playing techniques, but it still retains the basic characteristics and timbre of the konghou.

[0003] When the current konghou is in use, a tuning operation is required, that is, to adjust the effective length of the strings of the konghou, so as to change the effective string lengths of the strings on both sides of the konghou. Changing the effective string length will change the vibration frequency of the strings, and thus change the pitch of the emitted sound. At present, the konghou is provided with support columns for winding the strings on both sides of the konghou respectively, and then the strings are wound around the support columns by using an external force, so as to change the effective string length of the konghou for tuning. However, when winding the strings, pulling the strings by using an external force easily makes the connection between the strings and the support columns not firm, and the strings are easy to slip off, with low safety.

[0004] Therefore, in view of the above problems, it is necessary for the applicant to design a flexible tuning device for a modern konghou to solve the problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flexible tuning device for a modern konghou to solve the problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A flexible tuning device for a modern konghou, including a connecting plate detachably installed inside the konghou housing, and a first fastening mechanism is rotatably arranged on the connecting plate. A second fastening mechanism is rotatably arranged obliquely below the first fastening mechanism on the connecting plate, and the second fastening mechanism is the same as the first fastening mechanism. The first fastening mechanism and the second fastening mechanism are arranged in a flipped manner. The first fastening mechanism includes a connecting shaft rotatably connected to the connecting plate, and a winding block for winding the strings is fixedly arranged at one end of the connecting shaft extending outside the konghou housing. A string arranging member for abutting against the strings is fixedly arranged at the end of the connecting shaft away from the winding block and penetrating through the konghou housing.

[0007] Further, the vertical cross-section of the wire winding block is square to prevent the strings from slipping.

[0008] Through the above structural design, the wire winding block is set to be square, which is convenient for fastening the strings and preventing the strings from slipping.

[0009] Further, chamfers are provided at the four corners of the wire winding block.

[0010] Through the above structural design, the chamfers facilitate the strings to closely adhere to the wire winding block, improving the firmness of the connection between the strings and the wire winding block.

[0011] Further, waist-shaped grooves are formed on the outer side of the string arranging member, and the waist-shaped grooves are in contact with the strings.

[0012] Through the above structural design, the contact between the waist-shaped grooves and the strings facilitates controlling the direction of the strings, preventing the strings from shifting, and thus improving the tension degree of the strings.

[0013] Further, the strings wound around the wire winding block included in the first fastening mechanism are in contact with the waist-shaped grooves on the string arranging member included in the second fastening mechanism.

[0014] Through the above structural design, the effective lengths of the strings on both sides of the konghou can be adjusted by flipping the first fastening mechanism and the second fastening mechanism arranged.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The flexible tuning device of the modern konghou is convenient for adjusting the effective string length of the strings, and has a high adjustment firmness. The strings are not easy to slip, which is convenient for improving the safety when using the konghou. The specific content is as follows:

[0016] A first fastening mechanism and a second fastening mechanism arranged obliquely below the first fastening mechanism are provided. When in use, the strings are tied to the wire winding block, and the strings are in contact with the waist-shaped grooves. When tuning is required on both sides of the konghou, rotate the string arranging members on both sides of the konghou. The string arranging members will drive the connecting shaft to rotate, and the rotation of the connecting shaft will drive the wire winding block to rotate, tightening the strings, changing the effective string length, and having a high adjustment firmness. The strings are not easy to slip, which is convenient for improving the safety when using the konghou. BRIEF DESCRIPTION OF THE DRAWINGS
