Abstract

The utility model discloses a tuning device for tuning sound of strings, which comprises a housing, a gear transmission mechanism arranged in the housing, a rotating handle connected with a transmission shaft of an input gear of the gear transmission mechanism, and an adjusting sleeve connected with the transmission shaft of an output gear of the gear transmission mechanism, wherein the adjusting sleeve and the rotating handle are connected on a surface opposite to the housing, and a plurality of positioning sleeves are regularly arranged on a wall body of the housing on the periphery of the adjusting sleeve. Due to the adoption of a speed reduction transmission gear mechanism, the rotating angle can be micro-adjusted, thereby conveniently tuning the tension degree of the strings in place in a labor-saving manner and greatly improving the tuning efficiency.

Description

A kind of tuning device

Technical field

The utility model relates to musical instruments, relates in particular to a kind of tuning device that is used for adjustment string sound.

Background technology

Along with the development of society, people's quality of life and cultural quality improve constantly, and the demand of spiritual aspect becomes increasingly abundant.Musical instrument has been subjected to people's general liking, as, piano, harp, Zheng or dulcimer etc., be to send various beautiful sound by playing its string, people pass through shoegaze, can mind at rest, joyful psychosoma and improve cultural quality, so playing of musical instrument is more and more universal.In order to eject beautiful music, string all will carry out the adjustment of sound accuracy after a while, and people obtain correct sound by the tension force of tightening or loosen string.Current adjustment string all is the peg of directly rotating the tensioning string by special spanner, because the amount of spanner rotational angle should not be controlled, so the degree of string tensioning needs repeatedly to adjust back and forth, can adjustment put in place.Make adjustment efficient reduce like this, also inconvenient.

Summary of the invention

The utility model is to solve existing low, the inconvenient technical matters of string adjustment efficient, proposes a kind of easy to use, string tuning device that adjustment is fast.

For solveing the technical problem, the tuning device that the utility model proposes, the turning handle that it comprises shell, be located at gear drive in the shell, be connected with the transmission shaft of the input gear of gear drive, the adjustment sleeve that is connected with the transmission shaft of the output gear of this gear drive, this adjustment sleeve is connected on the opposite side of shell with described turning handle, and rule is provided with a plurality of abutment sleeves on the shell wall body around this adjustment sleeve.

In the preferred version, described gear drive is made of a pair of gear, and its pinion wheel is the input gear, and gear wheel is an output gear.

The transmission shaft of described turning handle and pinion wheel be connected can for fixedly connected, also can be releasable connection.

The utility model adopts the drive gear mechanism with certain reduction gear ratio to carry out the adjustment of string tensile force.To adjust sleeve earlier entangles and needs the peg of adjustment string head on the musical instrument, and other abutment sleeves around just in time entangling wouldn't adjustment the peg head of string, to stablize the utility model, shake turning handle then by gear drive and deceleration, the peg that is driven string by gear wheel is rotated, and obtains correct sound by the tension force of tightening or loosen string.Owing to adopted under drive gear mechanism, so that the rotational angle of peg can finely tune, can make things convenient for, easily, the labour-saving puts the degree adjustment of string tensioning in place, improved the efficient of adjustment greatly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:

Fig. 1 is the utility model preferred embodiment cut-open view;

Fig. 2 is the right view of Fig. 1.

Embodiment

Fig. 1 and Fig. 2 show the utility model preferred embodiment basic structure, described tuning device, and it comprises shell 1, is located at the gear drive in this shell, and in the present embodiment, this gear drive is made of the

gear

2,3 of a pair of big or small transmission.Pinion wheel 3 is the input gear, and the right-hand member of its transmission shaft is connected with a turning handle 4.And gear wheel 2 is an output gear, and the left end of its transmission shaft (end opposite with turning handle 4) connects one and adjusts sleeve 5, regularly on shell 1 wall body around this adjustments sleeve is provided with four abutment sleeves 6.In the present embodiment, adopt being connected of the transmission shaft of turning handle 4 and pinion wheel 3 fixedly connectedly, can certainly adopt releasable connection, so that carrier pack.The quantity of abutment sleeve 6 and between distance, generally be to design according to the distance between the peg of tensioning string on the different musical instruments, both shapes and distance etc. suitablely just can.Gear drive can also be made of a plurality of gears.

To adjust sleeve 5 during use earlier entangles and needs the peg of adjustment string head on the musical instrument, and other abutment sleeves 6 around just in time entangling wouldn't adjustment the peg head of string, to stablize the utility model, shake turning handle 4 then by gear drive and deceleration, the peg that is driven string by gear wheel 3 is rotated, and obtains correct sound by the tension force of tightening or loosen string.Owing to adopted under drive gear mechanism, so that the rotational angle of peg can finely tune, can make things convenient for, easily, the labour-saving puts the degree adjustment of string tensioning in place, improved the efficient of adjustment greatly.

Abovely the utility model is specifically described, but those skilled in the art can make numerous variations or variation to these embodiments these changes and changing within the scope that should fall into the utility model protection in conjunction with better embodiment.
