Universal prosthetic nail ring which can be fast worn and removed and is adjustable in tension for plucking musical instruments

Abstract

The invention relates to a universal prosthetic nail ring which can be fast worn and removed and is adjustable in tension for plucking musical instruments. The nail-benefiting ring comprises a mounting base, an adjusting rotary knob, a base pad and a binding band. A mounting part is recessed at one end of the mounting base, an elastic ratchet wheel ring is arranged on the inner side wall of the mounting part, mounting racks are arranged on the bottom wall of the mounting part, a binding band mounting slot runs inwards through the outer side of the mounting base and is located directly above the mounting racks, and the outer side of the adjusting rotary knob is provided with elastic ratchets meshed with the elastic ratchet wheel ring; a coaxial gear is disposed at one end of the adjusting rotary knob in a protrusive mode, the adjusting rotary knob is rotatably disposed in the mounting part, the base pad is disposed at the end, away from the rotary knob, of the mounting base, the two ends of the binding band are provided with first racks and second racks respectively, and the middle portion of the binding band is bent; the first and second racks are intersected in position, the firstracks are located on the outer sides of the second racks and meshed with the coaxial gear and penetrate through the binding band mounting slot, and the second racks penetrate through the binding bandmounting slot and are meshed with the mounting racks. The prosthetic nail ring is adjustable in tension and high in adaptability and can be fast worn and removed.

Description

technical field [0001] The invention relates to the technical field of an auxiliary device for a plucked stringed instrument, in particular to a tension-adjustable quick-release universal armor finger ring for a plucked stringed musical instrument. Background technique [0002] There are many kinds of plucked stringed instruments in modern times, such as zither and lute, etc. When playing, you need to wear armor on your fingertips, and use armor to pluck the strings to produce sound. The traditional way of wearing armor is to use adhesive tape to bind it. Its advantages are: first, it is stable, second, it has little interference with finger movement, third, it is not limited by the size of fingers, and fourth, the restraint on fingers is relatively soft and comfortable. . This is the most mainstream way of wearing at present, and it is almost the only way of wearing. The above-mentioned traditional armor wearing method is undoubtedly successful in terms of music and skill...

AI Technical Summary

Problems solved by technology

This armor is easy to put on and take off, and can match all finger sizes. However, due to the lack of plastic deformation ability of the copper sheet and the lack of elasticity, it cannot completely match the cross-sectional shape of the finger, resulting in the stability and stability of this armor finger cot. unacceptable comfort

At the same time, the playing texture and timbre of armor made of copper sheets cannot be compared with celluloid and nylon, and it is not professional, so it lacks practical value.

[0004] A kind of Velcro finger cot, which uses Velcro instead of adhesive tape. It is a flexible finger cot that can be easily taken off and put on. Its adaptability to finger size and wearing comfort are better than the previous one, but it is still There are disadvantages that cannot be overcome: one is that the material properties of the Velcro are soft and inelastic, and the tightness of the fingers is far less than that of the traditional adhesive tape, resulting in insufficient rigidity when the armor touches the strings, and the pronunciation is slow and soft; the second is that the thickness of the Velcro is much larger than Two layers of adhesive tape, and the frictional damping between the Velcro and the Velcro is very large. When two fingers need to be alternately plucked quickly, the Velcro rings on each finger interfere with each other and rub against each other when the fingers move alternately, which has a great influence on finger movement.

The above defects will seriously reduce the player's technical performance level, beginners can still try it out, but advanced players will not accept it
