Suspension type removes jack and is equipped with Huqin of suspension jack

Technical Field

The utility model relates to the technical field of musical instruments, in particular to a suspension type movable jack and a Huqin with the same.

Background

The urheen is a common musical instrument, and the urheen also comprises three urheen, chinese urheen, gaohu and the like. The existing Huqin comprises a Huqin body and a bow; one end of the string is fixed on the bottom of the string cylinder, and the other end of the string is connected with a string shaft on the string rod, which is far away from the string cylinder. The current Huqin adopts a mode of binding jack lines to determine the starting point position of Hu Qinkong chord tones, determines the starting point position according to the arm length, the placement height and other factors of different people, and winds and fixes the starting point position for a plurality of times by the jack lines after the optimal height and the finger comfort level are determined. However, when the binding position of the jack wire is adjusted, the jack wire needs to be disassembled and rebinding, the adjusting process is troublesome, the strings need to be adjusted again after each adjustment is completed, the strings can be disassembled repeatedly, and the efficiency is very low.

For example, publication No. CN210156092U discloses a two-stringed bowed instrument double-jack fine setting structure, including jack main part, regulation pole and regulation structure, two upper and lower through-holes side by side have been seted up to one side of jack main part, it includes interior string regulation pole and outer string regulation pole to adjust the pole, interior string regulation pole and outer string regulation pole all include the pole main part, the inside that the through-hole got into jack main part is passed to the one end of pole main part, the part that the pole main part is located jack main part is set up to worm portion, the chord groove has been seted up on the part circumference that the pole main part exposes outside the jack main part, regulation structure is provided with two altogether, and regulation structure is located the top of adjusting the pole, regulation structure includes the third axle. However, in practical application, the jack position cannot be flexibly and conveniently adjusted, the adaptability is poor, the mechanical transmission parts are too many, the adjustment process cannot be performed while the tuning is performed, more noise can be generated, and meanwhile, after the tuning is performed, the tuning correction is required because the transverse tension of the body to the string is changed.
