Abstract

The utility model relates to a non-notch Banhu fiddle bar mechanical tuning device for national musical instruments, being suitable for being used for national stringed instruments, such as an Erhu, a Zhonghu, a Gaohu, etc. The non-notch Banhu fiddle bar mechanical tuning device is composed of a worm bar fixed on a regulating handle, string hanging holes arranged on the outer end of the bar, a string hanging shaft fixed on a fiddle bar, a worm-wheel shaft connected with the string hanging shaft into integration, a worm wheel fixed on the worm-wheel shaft, a string shaft covering cap fixing the shafts and positioned on the end of the string hanging shaft and a fixing pad positioned on the end of the worm-wheel shaft. The utility model has simple structure and reasonable design and uses the worm wheel and the worm bar as a transmission mechanism, when the non-notch Banhu fiddle bar mechanical tuning device is installed, the non-notch Banhu fiddle bar mechanical tuning device can make the fiddle bar have integral and beautiful appearance and convenient assembly without destroying the fiddle bar.

Description

Non-notch banhu fiddle bar mechanical tuning device

Technical field

The utility model relates to a kind of quick mechanical tuning device of national musical instruments bowed stringed instrument with a thin wooden soundboard, is applicable to tuning a stringed instrument fast of national stringed instruments such as urheen, middle Hu, high Hu simultaneously.

Background technology

Bowed stringed instrument with a thin wooden soundboard is a kind of in the bowed instrument in the Chinese Musical Instruments, and urheen, recklessly middle, musical instruments such as high Hu are the same, all between two strings, spur and pronounce by the horse hair on the bow, generally be used for the accompaniment of song or opera because most employing is former in the position, the phenomenon that the ottava alta sound substitutes certain sound can appear in the accompaniment frequently, had afterwards and modify tone and change holders to draw and play, bowed stringed instrument with a thin wooden soundboard, urheen, recklessly middle, when musical instruments such as high Hu need to modify tone in the accompaniment process, adopt dual mode, the one, when modifying tone, needs stop accompaniment, use fixedly musical instrument tuner, by rotating peg tuner repeatedly, tuner was both slow and will pull out sound like this, had influenced performing effect, and another kind of mode is when needs modify tone, change another musical instrument of preprepared, though fast like this, when playing, need prepare several identical musical instrument, very inconvenient.The someone had invented that mechanical Chinese fiddle increases tumtum and the transposer of tuning a stringed instrument fast afterwards, it drives the string tuning by the rotation of worm gear and worm screw, only with once finishing the problem of playing the quick tuning of string midway to qin, because worm gear and worm screw must be fixed on the fixture, by this fixture worm gear and worm screw are fixed on the Chinese fiddle bar again, the profile that tuning device has destroyed the qin bar is installed like this, make on the qin bar cut is arranged, very not attractive in appearance, also destroyed simultaneously the wood fibre structure of banhu fiddle bar, cause banhu fiddle bar intensity to reduce, the easy deformation bending influences tonequality.

The utility model content

The purpose of this utility model be design a kind of still with worm gear and worm screw as the tuning device that does not have housing mount of gear train, can not destroy the qin bar during installation, make qin bar outward appearance complete attractive in appearance, promote qin rod fibers intensity, improve tonequality purity.

The purpose of this utility model is to realize like this, he is provided with string hanging hole by being fixed on scroll bar, the bar outer end regulated in the handle, be fixed on extension peg on the qin bar, with hang turboshaft that peg connects as one, be fixed on turbine on the turboshaft, stationary shaft be positioned at the peg block of hanging the peg end, the setting-up piece that is positioned at the turbine axle head constitutes.When need regulating, only need to rotate handle, the scroll bar that handle drives in the handle rotates, and the rotation of scroll bar drives turbine rotation, and the rotation of turbine drives turboshaft and rotates, and turboshaft rotates to drive and hangs peg and rotate, and hangs peg and rotates and make string open, relax to change adjusting.

Non-notch banhu fiddle bar mechanical tuning device described in the utility model is simple in structure, reasonable in design, has kept worm gear and worm screw as gear train, do not have external fixture, can not destroy the qin bar during installation, make qin bar outward appearance complete attractive in appearance, easy to assembly, use is convenient and simple, and stationarity is good.

Embodiment

With reference to the accompanying drawings non-notch banhu fiddle bar mechanical tuning device structure described in the utility model is described in detail below.

Get an about 7mm Metallic rod of diameter, be processed into the worm screw that an end is a screw thread (2), the other end is made a call to an aperture, hole at the about 5mm of handle (7) centre drill one diameter, in the narrow meshed end load hole of worm screw, passing aperture with pin fixes worm screw and handle, Metallic rod with the about 8mm of diameter, be processed into a turboshaft (3) and hang the connecting shaft of peg (4), for attractive in appearance, be exposed to the outer end of qin bar and be processed into round end, the hole that end machining one is hung string, turboshaft can be processed into square, metal with the about 10mm of a diameter is processed into turbine (1), the turbine center is processed into the hole that is complementary with turboshaft, turbine is enclosed within on the turboshaft, fix with pin, go up at qin bar (8) and make a call to a hole (9) or (10), diameter and setting-up piece are complementary, length and axial length are complementary, at the mouth end is screw thread, is screw thread with the appearance that processes, and the center is that pad (6) load hole of circular hole is fixed, again with the turbine that assembles, insert the pad hole and fix, precession center, outer end is the peg block (5) in hole, and peg block bore dia is complementary with extension peg diameter.

Claims

1. non-notch banhu fiddle bar mechanical tuning device, it is characterized in that: it is to be provided with string hanging hole by being fixed on scroll bar, the bar outer end regulated in the handle, be fixed on extension peg on the qin bar, with hang turboshaft that peg connects as one, be fixed on turbine on the turboshaft, stationary shaft be positioned at the peg block of hanging the peg end, the setting-up piece that is positioned at the turbine axle head constitutes.
