The utility model is characterized in that the shaft is respectively provided with a string adjustment device, the string adjustment device comprises a bracket fixed on the rod, two mutually separate worm wheels and worm regulators which are arranged on the bracket in parallel, and a tripping lever fixedly connected with the shaft; the bow adopts a two-tail adjustable structure and is provided with an adjustment device which is composed of two buttons, two worms, a worm wheel and a casing. The utility model has the advantage that the vocal range is enlarged, and the utility model can solve the problem of modulation which can not be solved for a long time.

Description

Four-stringed erhu

The utility model relates to a kind of stringed musical instrument.

Urheen occupies critical role in China national orchestra, be main rhythm instrument, often serve as the solo part in musical works, the tone color of urheen is mellow and full soft and graceful, have abundant expressive force, not only be good at soft careful cavatine but also can show active cheerful and light-hearted ardent scene and the vast scene of imposing manner.Yet, since the original process structures shape of urheen its limitation, (1). urheen has only two strings, two octaves of usable range, the best range of sound has only one and half octaves, and orchestral music " Liang shanbo and Zhu yingtai " go everywhere without any hindrance here on violin, on urheen, but can't finish, because do not had sound.(2). again because urheen is made up of two strings, and modulation has just become headachy problem on the Erhu playing, a modulation, related key especially far away, available note remains little, and the unisonance that can only use another octave substitutes, and can't satisfy and finish works.

The purpose of the utility model provides a kind of Four-stringed erhu that can enlarge range, strengthen expressive force.

The technical solution of the utility model is: Four-stringed erhu is made of qin tube 1, qin bar 2, very heavy 3, qin axle 4, bow 5, string 6, it is characterized in that: a string regulating device 7 is set respectively on the described qin axle, this regulating device by one be fixed in the support 8 on the qin bar 2, two the separate worm gears 9 that be arranged in parallel on support 8, worm screw 10 regulators are formed with a trip(ping) lever 11 of fixedlying connected with qin axle 4.Each regulating device is divided into third gear, shelves, neutral gear, overside in being respectively, and each fixes a regulating wheel 12 that is used to tightly wrap string 6 wherein about two grades worm gear 9, and this regulating wheel 12 is coaxial with worm gear 9.Such two qin axles twine four strings altogether, do not disturb mutually.Described bow 5 adopts two tail adjustable structures, is provided with two tail regulating devices 13 on bow 5.This regulating device is made of the housing 17 of two buttons 14, two worm screws (15,19), a turbine 16 and a regulating device.Be provided with two worm screw sliding trays 18 in the described housing 17, rear end between two worm screws (15,19) is provided with worm gear 16, wherein the middle part of a worm screw is provided with groove 20, match with two buttons 14 respectively in the two ends, the left and right sides of this groove 20, the end of described worm screw (15,19) is provided with the screw 22 that matches with manyleaf meadowure rhizome and root joint 21.

The utility model has the advantages that to have enlarged range, can solve unsolved for a long time modulation problem.

Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:

Fig. 1: be Four-stringed erhu structural representation of the present utility model;

Fig. 2: for figure cuts open in qin axle governor motion of the present utility model office;

Fig. 3: be bow regulating device structure cut-away view of the present utility model;

Fig. 4: be bow regulating device structure A-A cut-away view of the present utility model.

Four-stringed erhu of the present utility model is on the basis of existing urheen, on qin axle 4 and bow 5, sets up a string regulating device 7 and two tail regulating device 13 respectively.Described qin axis adjustment device 7 is made of two separate worm gears 9 that be arranged in parallel, worm screw 10 and a trip(ping) lever 11, inboard worm screw 10 is the hollow cylinder body structure, trip(ping) lever 11 was scurried this hollow worm gear 10, the one end is fixedlyed connected with qin axle 4, the other end is a clutch gear 23 between two worm screws 10, every qin axle 4 just is divided into third gear like this, shelves, neutral gear, overside in being respectively.When qin axle 4 is in the home record position, the inner tines of the clutch gear 23 of trip(ping) lever 11 1 ends be meshed with the outside tooth of worm screw 10 (Fig. 2), regulate qin axle 4 like this and just can regulate inboard string 6, otherwise when the qin axle is in the overside position, the outside tooth of the clutch gear 23 of trip(ping) lever 11 1 ends is meshed with the inner tines of worm screw 10, regulates qin axle 4 like this and just can regulate outside string 6.Described bow 5 is two tail regulating devices, this regulating device is made of two buttons 14, two worm screws (15,19), worm gear 16 and housing 17, in housing 17, be provided with two sliding trays 18 for the worm screw slip, rear end between two worm screws is provided with worm gear 16, wherein the middle part of a worm screw 15 is provided with groove 20, match with two buttons 14 respectively in the two ends, the left and right sides of this groove, the end of two worm screws is provided with the screw 22 that matches with manyleaf meadowure rhizome and root joint 21.String of two horse hairs on the bow is between the 1st, 2 string, and another root string is between the 3rd, 4 string.When the next button, horse hair is tightened up can the pronunciation performance, and another root side can not produce dried around, vice versa.
