Set；Described potentiometer main body includes that the carrier board being loaded with resistance, described carrier board are patty, and it is arranged at the bottom of above-mentioned housing
Portion；Described resistance is fold-line-shaped circular ring structure, and it is arranged on described carrier board upper surface；It is additionally provided with slip on described carrier board
Contact, described sliding contact one end is fixed on described carrier board center by contact support, and the other end slides with described resistance
Connect；The fixing end of described sliding contact is also connected with rotation bar, and described rotation bar is through described upper shell top axle sleeve and sets
Put on described casing center axis；Described rotation bar includes metal inside and non-graphite outer layers.
Further, described contact support upper surface annularly side face is provided with the locating piece of multiple projection, described cunning
Movable contact lower surface is provided with the locating slot that multiple and described locating piece is corresponding.
Further, described transparent three-proofing coating uses polyurethane resin coating.
Further, the metal inside of described rotation bar and non-graphite outer layers are by gluing connection.
The invention has the beneficial effects as follows: the mould-proof-type potentiometer of the present invention, by resistance is set to fold-line-shaped structure, has
Effect increases the maximum of resistance, and is connected with the bending part of resistance by sliding contact, it is possible to according to the bending number of resistance
Amount and degree arrange the different accuracy of potentiometer, improve the convenience of use；Recycle transparent three-proofing coating and make current potential utensil
There is the property of protection against the tide, it is to avoid potentiometer occurs aging because getting rusty, and extends its service life.
Accompanying drawing explanation
Fig. 1 is the mould-proof-type potentiometer schematic cross-section of the present invention.
Fig. 2 is the potentiometer main body top view of the present invention.
Wherein, housing 1, axle sleeve 1-1, transparent three-proofing coating 1-2, potentiometer main body 2, carrier board 2-1, resistance 2-2, slide and touch
Point 2-3, contact support 2-4, rotate bar 2-5.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, not
For limiting the present invention.
As it is shown in figure 1, be the mould-proof-type potentiometer schematic cross-section of the present invention.A kind of mould-proof-type potentiometer, including housing 1
And the potentiometer main body 2 being arranged in housing 1；Described housing 1 uses cylindrical enclosed construction, and its inner surface and outer surface are equal
Being provided with transparent three-proofing coating 1-2, top is provided with axle sleeve 1-1；Described potentiometer main body 2 includes the carrier board 2-being loaded with resistance 2-2
1, described carrier board 2-1 is patty, and it is arranged on bottom above-mentioned housing 1；Described resistance 2-2 is fold-line-shaped circular ring structure, its
It is arranged on described carrier board 2-1 upper surface；Sliding contact 2-3, described sliding contact 2-3 it is additionally provided with on described carrier board 2-1
One end is fixed on described carrier board 2-1 center by contact support 2-4, and the other end is slidably connected with described resistance 2-2；Described
The fixing end of sliding contact 2-3 is also connected with rotation bar 2-5, and described rotation bar 2-5 passes described upper shell 1-1 top axle sleeve 1-
3 and be arranged on described housing 1 central axis；Described rotation bar 2-5 includes metal inside and non-graphite outer layers.
The metal inside of the rotation bar 2-5 of the present invention and non-graphite outer layers are by gluing connection, and non-graphite outer layers is soft graphite,
There is the chemical stability of native graphite, anti-erosion, outside the characteristics such as lubricity is good, also there is special flexibility and elasticity, have one
Fixed sealing property.Transparent three-proofing coating 1-2 of the present invention uses polyurethane resin coating, has protection against the tide, puts salt fog, anti-mildew etc.
Property, and smear clear bottom, brightness height, it is coated with rear surface outward appearance preferable.
As in figure 2 it is shown, be potentiometer main body 2 top view of the present invention.The resistance 2-2 of the potentiometer main body 2 of the present invention is
Fold-line-shaped circular ring structure, its lines are uniformly or non-uniformly bar shaped, at the side near the carrier board 2-1 center of circle, its kink
Divide and be slidably connected with sliding contact 2-3, the different essences of potentiometer can be set by the bending quantity and degree arranging resistance 2-2
Degree.So that sliding contact 2-3 is more reliable and more stable in sliding process, the present invention is on contact support 2-4 upper surface edge
Ring-shaped periphery is provided with the locating piece of multiple projection, sliding contact 2-3 lower surface is provided with multiple and described locating piece corresponding
Locating slot, resistance 2-2 bending part that locating piece here and locating slot all and are connected with sliding contact 2-3 and carrier board 2-
