When, the annular projection 22 rotates in the circular trough 11, because upper cover plate 5 is connected with lower cover 1, in both common works
Under, the rotational trajectory of the annular projection of the bottom of knob 2 can be limited in the circular trough 11 of lower cover 1 so that turn knob 2
The situation that the skew of the rotational trajectory of knob 2 occurs for Shi Buhui or knob loosens；
Further, in embodiments of the present invention, in embodiments of the present invention, to be additionally provided with ring-type on the knob 2 convex
Platform 23, the upper cover plate 5 abut with annular boss 23, and specifically, the annular boss 23 is arranged at the inner side of knob 2, is used for
Upper cover plate 5 is carried, now, the rotational trajectory of knob 2 can be limited by circular trough 11 and upper cover plate 5, ensures knob 2 in circular trough
Stable rotation on 11, that is, cause gear 3 can be stablized to drive encoder 4, that is, ensure to can be very good to grasp with turn knob 2
The regulation operation of regulation or bright darkness to class such as volume；
In embodiments of the present invention, the top of annular boss 23 is set to circular arc, can so reduce in turn knob 2
Very big frictional force will not be produced because upper cover plate 5 is contacted with annular boss 23, so as to ensure that the smoothness of the rotation of knob 2
Property.
Optionally, in the lower section of upper cover plate 5, set that fluted (figure is not corresponding to the position of annular boss 23
Show), the annular boss 23 is adapted with the groove, and when knob 2 rotates, annular boss 23 rotates in the groove,
While ensureing the fluency that knob 2 rotates, it can also equally play a part of limiting the rotational trajectory of knob 2.
In other embodiments of the invention, above-mentioned encoder 4 can also be potentiometer.
Knob side provided by the invention rotational structure, by rotation of the turn knob 2 with moving gear 3, compiled so as to drive
The shaft core 41 of code device 4 rotates, and the rotary angle signal of shaft core 41 is converted into electric signal transmission to the control electricity of external pcb board
Road, it is achieved thereby that the regulatory function of class such as volume or bright darkness, the pivot in the present invention due to gear 3 deviates
The pivot of knob 2, and the diameter of knob 2 is much larger than the diameter of gear 3, so can be in the less feelings of the anglec of rotation of knob 2
Under condition, realize 360 degree of gear 3 rotations, you can realize 360 degree of the shaft core 41 of encoder 4 it is fully rotating, realize by a small margin
The can of turn knob 2 completes gamut adjustment, for example volume or bright darkness adjust from minimum to highest, meanwhile, it is not required to
Want the support of central shaft so that overall structure is simple and easy to operate.
Embodiment two
