Abstract
The invention discloses a mould-proof moisture absorption potentiometer which comprises a lower shell and an upper shell. The inner surface and the outer surface of the upper shell and the inner surface and the outer surface of the lower shell are coated with transparent three-proofing paint. A shaft sleeve is arranged at the top of the upper shell, a cavity is formed between the lower shell and the upper shell, and a rotary shaft, a conductive rotary sheet, a first fixed connecting pin sheet, a second fixed connecting pin sheet, a movable connecting pin sheet and an arc resistor are arranged in the cavity. The rotary shaft is matched with the shaft sleeve and comprises an inner metal core and an outer graphite layer, and the first fixed connecting pin sheet and the second fixed connecting pin sheet are connected to the two ends of the arc resistor respectively. In this way, the potentiometer has the special performance of dampness prevention, salt mist prevention and mould prevention, it is avoided that the potentiometer rusts to age, and the service life of the potentiometer is prolonged.
Description
Technical field
The present invention relates to potentiometer field, particularly relate to a kind of mildew-resistant moisture absorption type potentiometer.
Background technology
Potentiometer be there are three exits, resistive element that resistance can be regulated by certain Changing Pattern, potentiometer is generally made up of resistive element and moveable brush.Potentiometer is installed in enterprising enforcement of various equipment and uses, play regulation effect, existing rotational potentiometer lubricity is poor, fretting wear is big, when potentiometer uses environment moister, be easily accessible moisture, long-time after easily cause the oxidation and going mouldy of getting rusty of potentiometer, it is substantially reduced the normal service life of potentiometer, thus increases use cost.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of mildew-resistant moisture absorption type potentiometer, has protection against the tide, Defend salt fog, anti-mildew property, it is to avoid potentiometer occurs because getting rusty aging, extends its service life.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of mildew-resistant moisture absorption type potentiometer, it is characterized in that, including: lower house, upper shell, described upper shell is all painted with transparent three-proofing coating with the surfaces externally and internally of lower house, described upper shell top is provided with axle sleeve, a cavity is formed between described lower house and upper shell, cavity inside is provided with rotating shaft, conduction revolving fragment, first fixed pin sheet, second fixed pin sheet, dynamic pin sheet and circular arc resistance body, described rotating shaft matches with described axle sleeve, described rotating shaft includes metal inside and non-graphite outer layers, the first described fixed pin sheet and the second fixed pin sheet are connected to the two ends of circular arc resistance body.
In a preferred embodiment of the present invention, described transparent three-proofing coating is polyurethane resin coating.
In a preferred embodiment of the present invention, described transparent three-proofing coating is brushed by baking, at potentiometer surfaces externally and internally film-forming.
In a preferred embodiment of the present invention, described non-graphite outer layers is expanded graphite.
In a preferred embodiment of the present invention, described metal inside is connected by epoxide-resin glue is gluing with non-graphite outer layers.
The invention has the beneficial effects as follows: potentiometer provided by the present invention has protection against the tide, Defend salt fog, anti-mildew property, it is to avoid potentiometer occurs aging because getting rusty, and extends its service life.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the present invention a kind of mildew-resistant moisture absorption type potentiometer one preferred embodiment；
In accompanying drawing, the mark of each parts is as follows: 1-lower house, 2-upper shell, 3-axle sleeve, 4-rotating shaft, 5-metal inside, 6-non-graphite outer layers, the transparent three-proofing coating of 7-.
Detailed description of the invention

Described transparent three-proofing coating 7 is polyurethane resin coating, and this film has protection against the tide, Defend salt fog, anti-mildew NBC protective performance, and film transparency, and brightness is high, is coated with rear surface outward appearance preferable.
Described transparent three-proofing coating 7 is brushed by baking, at potentiometer surfaces externally and internally film-forming, toasts film forming, and performance is more preferably.
Described non-graphite outer layers 6 is expanded graphite, and this graphite, except having the chemical stability of native graphite, anti-erosion, outside the characteristics such as lubricity is good, also has special flexibility and elasticity, has certain sealing property.
Described metal inside 5 is connected by epoxide-resin glue is gluing with non-graphite outer layers 6.
Potentiometer provided by the present invention has protection against the tide, Defend salt fog, anti-mildew property, it is to avoid potentiometer occurs aging because getting rusty, and extends its service life.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
