Abstract
The present invention discloses a potentiometer knob structure with a scale. The potentiometer knob structure comprises a scale round disc and a cylindrical plastic cap. The middle part of the scale round disc is provided with a round hole through which the cylindrical plastic cap passes. The bottom of the cylindrical plastic cap is provided with a groove which is matched with potentiometer rotation shaft. The outer side face of the cylindrical plastic cap is provided with a first arc concave part which can be held by a forefinger and a second arc concave part which can be held by a thumb, and the first arc concave part and the second arc concave part are cylindrically arranged. Through the above mode, the potentiometer knob structure has the advantages of simple and reasonable structure and high reliability, and force is uniform in use.
Description
Technical field
The present invention relates to potentiometer technical field, particularly relate to a kind of potentiometer knob structure with a scale.
Background technology
Potentiometer be there are three exits, resistive element that resistance can regulate by certain Changing Pattern.Potentiometer is made up of resistive element and moveable brush usually.Potentiometer is installed in the enterprising enforcement use of various equipment, plays regulating action.
Rotational potentiometer is the many a kind of potentiometers used in potentiometer.The rotating shaft outside need of rotational potentiometer coordinates knob, is convenient to people and rotates.Current this knob rotates discontinuity, and rocking of axle is large, and the contact between brush and resistive element is unreliable.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of potentiometer knob structure with a scale, simple and reasonable, and use stressed relatively more even, reliability is high.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of potentiometer knob structure with a scale, comprise: dial disc and cylindrical plastic cap, there is in the middle part of described dial disc the circular hole passed for cylindrical plastic cap, there is bottom described cylindrical plastic cap the groove matched with potentiometer turning axle;
The lateral surface of described cylindrical plastic cap has the first circular arc recess pinched for forefinger and the second circular arc recess pinched for thumb, described first circular arc recess and the second circular arc recess are symmetrical arranged.
In a preferred embodiment of the present invention, described groove semicircular in shape or regular hexagon.
In a preferred embodiment of the present invention, the first circular arc recess has anti-skidding lines.
In a preferred embodiment of the present invention, the second circular arc recess has anti-skidding lines.
The invention has the beneficial effects as follows: the potentiometer knob structure that the present invention is with a scale, simple and reasonable, use stressed relatively more even, reliability is high.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the present invention's potentiometer knob structure one preferred embodiment with a scale.
In accompanying drawing, the mark of each parts is as follows: 1, dial disc, and 2, cylindrical plastic cap, 3, groove, the 4, first circular arc recess, the 5, second circular arc recess.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of potentiometer knob structure with a scale, comprise: dial disc 1 and cylindrical plastic cap 2, there is in the middle part of described dial disc 1 circular hole passed for cylindrical plastic cap 2, there is bottom described cylindrical plastic cap 2 groove 3 matched with potentiometer turning axle, can be more accurate when described dial disc 1 makes potentiometer regulate.
The lateral surface of described cylindrical plastic cap 2 have the first circular arc recess 4 pinched for forefinger and the second circular arc recess 5 pinched for thumb, described first circular arc is recessed, 4 and second circular arc recess 5 be symmetrical arranged, during adjustment, forefinger and thumb pinch the first circular arc recess 4 and the second circular arc recess 5 respectively, use stressed relatively more even, reliability is high.
Preferably, described groove 3 semicircular in shape or regular hexagon.
Preferably, the first circular arc recess 4 has anti-skidding lines, skid when avoiding rotating.
Preferably, the second circular arc recess 5 has anti-skidding lines, skid when avoiding rotating.
The invention has the beneficial effects as follows: the potentiometer knob structure that the present invention is with a scale, simple and reasonable, use stressed relatively more even, reliability is high.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
Claims (4)
