The present invention is easy to use and adjustment is accurate, can effectively solve the problem that it is difficult that an ancient plucked stringed instrument in the prior art is tuned a stringed instrument.
Description of drawings
Fig. 1 is the diagrammatic cross-section of string fine setting device of the present invention;
Fig. 2 is that string fine setting device of the present invention is mounted to the schematic diagram on an ancient plucked stringed instrument qin body.
Embodiment
The below describes the present invention with reference to the accompanying drawings.
As shown in Figure 1, string fine setting device proposed by the invention comprises axle 1, tapered sleeve 2, sliding sleeve 3, gear 4, gear 5, gear 6, gear 7, knob 8.Axle 1 is as a whole, but it prolongs axial distribution is some joints, each joint is similar to a right cylinder, be step-like transition between joint and the joint, each cylindrical cylindrical cuts radius of circle and successively decreases successively from the bottom to top, is provided with 1 or 2 through hole for winding up at the bottom of axle 1 joint (i.e. a maximum joint that cuts radius of circle).Tapered sleeve 2 endoporus are step-like hole, its inside surface and axle 1 step outer surface cunning are joined, the outside surface of tapered sleeve 2 prolongs and axially is two joints, can be described as top joint and below joint, each joint is similar to a cylinder, is step-like transition between two joints, and it is larger than the top joint that below joint cylindrical cuts radius of circle, wherein, the part of axle 1 except the joint of bottom all is nested in the tapered sleeve 2.In addition, combine closely with wooden frame because the below of tapered sleeve 2 joint will embed in an ancient plucked stringed instrument qin body, so the below of tapered sleeve 2 joint also can be made into other cross sectional shapes that can be complementary with an ancient plucked stringed instrument qin body.Outer round and smooth the joining of the endoporus of sliding sleeve 3 and tapered sleeve 2 tops joint, the outside surface of sliding sleeve 3 is similar to a cylinder, has 1 or 2 through hole to be used for winding up on it.The radius of circle that cuts of sliding sleeve 3 through holes should be identical with section radius of circle of joint through hole, axle 1 bottom.Gear 4,5,6 is arranged in co-axial alignment from the bottom to top, is fixed together with sliding sleeve 3 upper ends, tapered sleeve 2 upper ends and axle 1 upper end respectively; Gear 4,5,6 external diameter are identical, and gear 4,6 the number of teeth are identical, and gear 5 has adopted the number of teeth different with them, so said gear 4,5,6 has consisted of a differential gear set.Gear 7 has two, be the column gear, be installed in knob 8 inside, the upper end is supported with pin 9 respectively, two gears 7 are respectively from both sides while and gear 4,5,6 interlocks, knob 8 is connected with axle 1 by open washer 10, makes knob 8 produce axial float at the Shi Buhui that rotatablely moves that does take axle 1 as axial line.
In the present invention, tapered sleeve 2 embeds in an ancient plucked stringed instrument qin body wooden frame, combine closely by conical surface friction power and wooden frame, therefore gear 5 is fixed on the tapered sleeve 2 is relatively static in the motion of sleeve mechanism, turning knob 8 drives two gears 7 and rotates around the axle center of knob, gear 7 also rotates around Pivot Point Center simultaneously, because differential gear set middle gear 4,6 and the number of teeth difference of gear 5, therefore make gear 4,6 produce the relative angle speed with gear 5, thereby axle 1 is begun with identical angular velocity rotation with sliding sleeve 3 relative tapered sleeves 2, play synchronous adjustment and pass the effect of the two strings in axle 1 through hole and sliding sleeve 3 through holes, and so that the rotation of knob 8 and axle 1 and sliding sleeve 3 has produced larger reduction gear ratio, also had simultaneously auto-lock function.Knob adopts the plastics manufacturing with damping capacity to form, thereby when making rotation preferably feel is arranged.
Fig. 2 shows the schematic diagram that string fine setting device proposed by the invention is combined with an ancient plucked stringed instrument qin body, when needs are adjusted scale, clockwise, be rotated counterclockwise knob 8, the simultaneously tensioning of power that namely can be same, lax two strings 11 that pass and 12.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
