Embodiment
Embodiment:
The structural representation of tuner of the present utility model as shown in Figure 6, comprise resonance housing 4 and resonant rod 5, resonant rod 5 is placed in the hollow cavity set by resonance housing 4, the top of resonance housing 4 is provided with cover plate 1, it is characterized in that cover plate 1 being equiped with tuning screw 2 and self-locking reed 3, tuning screw 2 includes thread segment 21 and polished rod section 22, self-locking reed 3 is fixed on the medial surface of cover plate 1, and self-locking reed 3 is provided with the breach in the ridge that can be stuck in thread segment 21 set by tuning screw 2, thread segment 21 and the cover plate 1 of tuning screw 2 are threaded connection, the polished rod section 22 of tuning screw 2 is placed in the hollow cavity set by resonance housing 4 through the breach set by self-locking reed 3, and the axis of the polished rod section 22 of tuning screw 2 and the axis collinear of resonant rod 5.
In the present embodiment, the diameter of above-mentioned polished rod 22 is less than the diameter of thread of thread segment 21, and polished rod 22 is easier to through the screwed hole set by cover plate 1 and self-locking reed 3.
In the present embodiment, the end of the thread segment 21 of above-mentioned tuning screw 2 is provided with and facilitates tuning regulating tank 23.
In the present embodiment, the regulating tank 23 that above-mentioned thread segment 21 is provided with is in-line groove, or cross bath.
In the present embodiment, above-mentioned self-locking reed 3 includes the both sides that the first reed 31 and the second reed 32, first reed 31 and the second reed 32 are fixed on cover plate 1 medial surface.
First reed 31 of above-mentioned self-locking reed 3 and the second reed 32 are fixed on tuning screw 2 by spot welding.In the present embodiment, the first reed 31 of above-mentioned self-locking reed 3 and the second reed 32 are provided with 8 solder joints 33.
In the present embodiment, above-mentioned first reed 31 and the second reed 32 are provided with the breach in the ridge that can be stuck in thread segment 21 set by tuning screw 2.
In the present embodiment, the breach that above-mentioned first reed 31 and the second reed 32 are provided with is circular arc cutaway.
In the present embodiment, above-mentioned first reed 31 and the circular arc cutaway set by the second reed 32 are oppositely arranged, and the cavity area that two arc gaps are formed is less than the area of section of the thread segment 21 of tuning screw 2.First reed 31 of described self-locking reed 3 and one end of the second reed 32 are connected, and make circular arc cutaway in the junction of the first reed 31 and the second reed 32, set circular arc cutaway structure can adopt the techniques such as Linear cut to make.
In addition, the thickness of above-mentioned self-locking reed 3 is less than the thread pitch of tuning screw 2.First reed 31 of self-locking reed 3 and the second reed 32 have certain rigidity and elasticity; When tuning screw does not assemble, the first reed 31 of self-locking reed 3 and the second reed 32 are smooth.
The operation principle of tuner of the present utility model is: tuning screw 2 is through after the screwed hole of cover plate 1 and self-locking reed 3, because the space of two circular arc cutaway is less than thread segment, self-locking reed 3 has flexible first reed 31 and the second reed 32 forces are applied flexural deformation to a certain extent, increase space to hold the thread segment 21 of tuning screw 2, the arc gap of reed is stuck in ridge.There is flexible reed due to restorable trend, active force is produced to tuning screw 2, this active force can be decomposed into axial force and radial load, and radial load achieves the locking of reed to screw, and axial force makes reed and cover plate acting in conjunction realize further tuning screw lock.During adjustment, adjustment means turns tuning screw 2, and tuning screw 2 changes with the relative position of resonant rod 5, thus reaches the object changing frequency.
