Description
Technical field
The utility model relates to musical instrument fields, more specifically, it relates to a kind of adjustable chromatic scale mouth of key press
Qin.
Background technique
Chromatic harmonica is from traditional mouth organ improvement, and using one, cleverly inflexion plate key can be in a mouth organ
Lifting semitone is played out above, because its range is wide, and is convenient for transposition or modulation, is promoted rapidly in recent years, is often applied to mouth organ
It instrumental ensembles and multiple plays.Bassoonist is because individual hand strength strength is different, and pressing keys dynamics demand is different, and keystroke dynamics are big
The small spring part torque magnitude by connection inflexion plate restrains, and former spring part structure is as shown in figure 3, torsional spring torsion is single non-adjustable
It is whole, the adjusting to vary with each individual cannot be achieved.Mouth organ is pressing in use process repeatedly simultaneously, and spring part torsion is smaller and smaller, presses
Key bullet speed also just gradually becomes smaller, and sensitivity then becomes worse and worse.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of keys to solve the above problems
The chromatic harmonica of pressure adjustable section, rotating threaded shaft adjust torsional spring torque magnitude, adjust inflexion plate bullet on demand and move dynamics.
To achieve the above object, the utility model provides following technical solution:
The adjustable chromatic harmonica of key press, including it is located in the middle Qin Ge, the upper spring successively assembled above qin lattice
Plate, upper cover plate, lower reed plate that lower section successively assembles, lower cover plate, inflexion plate that front side wall successively assembles, mouthpiece, the inflexion plate
Right end protrudes key, is equipped with spring part inside qin lattice right end, and spring part connects inflexion plate, pressing keys inflexion plate Qin Ge with
Left and right displacement between mouthpiece, the spring part include positioning column, torsional spring, lead screw, and Qin Genei lead screw is arranged in parallel with inflexion plate, silk
The screw rod right end of bar is located at qin especially, and for torsion spring set on the positioning column on rear side of lead screw, inside torque arm is resisted against lead screw
On the right side of nut, outside torque arm is connected on inflexion plate.By rotary screw, the torque of adjustable torsional spring is reached with adjusting torsion
To the function of changing the shifting sensitivity of inflexion plate bullet.
The utility model is further improved technical solution, and the end face of the screw rod right end, which is equipped with, adjusts spin slot.Adjust rotation
Slot can be cross or "-" type, play rotation using cross or a word, adjust more convenient, light.
The utility model is further improved technical solution, and the inflexion plate is equipped with perforation, and the outside torque arm of torsional spring is inserted
Enter in perforation.Jack connection, it is convenient for disassembly and assembly.
The utility model is further improved technical solution, and the positioning column center is equipped with threaded hole, and upper square bolt passes through
Upper cover plate, upper spring plate are screwedly mounted in threaded hole, and assembling upper cover plate, upper spring plate are connected on qin lattice.Positioning column is both when torsional spring is fixed
Frame, and as mouth organ component assembling hole, it is compact-sized.
It further includes the steel part top plate being fixed on qin lattice, top plate right side that the utility model, which is further improved technical solution to be,
Wall center is equipped with groove, and the screw rod left end of screw rod is resisted against in top plate groove.Bad modeling is pushed up in screw rod left end in precession in order to prevent
Materials and parts qin lattice, steel part top plate play a very good protection, and steel part top plate against, lead screw adjust after be not susceptible to deviate,
Stability is good.
The utility model compared with prior art, has the advantage that
Existing chromatic harmonica structure, the controlled torsional spring torsion of inflexion plate is possessed by its certain time point itself, can not
Change, therefore can not be adjusted due to each one hand-power size moves sensitivity requirement difference to inflexion plate bullet.
And existing structure, torsional spring torsion after pressing a period of time can gradually become smaller, and inflexion plate key bullet speed will
Become smaller, deterioration of sensitivity needs to increase torsion at this time, then rotary screw adjusts torque, restores sensitivity.
Detailed description of the invention
Fig. 1 is the utility model front view；
Fig. 2 is the overlooking structure figure that Fig. 1 removes upper cover plate, upper reed plate；
Fig. 3 is existing chromatic harmonica schematic diagram of internal structure.
Specific embodiment
As shown in figure 3, existing chromatic harmonica, it is only that a torque arm is directly connect with inflexion plate that internal torsional spring, which is fixed,
Torsion is single to be cannot be adjusted.
As shown in Figure 1 and Figure 2, the utility model includes being located in the middle qin lattice 5, the upper spring plate successively assembled above qin lattice
(not shown), upper cover plate 8, lower reed plate (not shown) that lower section successively assembles, lower cover plate 9, front side wall successively assembles
Inflexion plate 6, mouthpiece 7, be screwed.6 right end of inflexion plate protrudes key 61, is equipped with spring inside 5 right end of qin lattice
Part, spring part connect inflexion plate, 61 inflexion plate 6 of pressing keys left and right displacement between qin lattice 5 and mouthpiece 7, the spring part packet
Positioning column 1, torsional spring 2, lead screw, top plate 4 are included, lead screw is arranged in parallel with inflexion plate 6 in qin lattice 5, and top plate 4 is fixed on qin lattice, top
4 right side wall center of plate is equipped with groove, and 31 left end of screw rod of screw rod is resisted against in 4 groove of top plate, the 31 right end position of screw rod of screw rod
Especially in qin, end face is equipped with "-" type or cross tune spin slot, and torsional spring 2 is sleeved on the positioning column 1 on rear side of lead screw, in
Side torque arm 21 is resisted against 32 right side of nut of lead screw, and outside torque arm 22 is connected on inflexion plate 6, and connection type is on inflexion plate 6
