Body；Described housing uses cylindrical enclosed construction, and outer surface is provided with moist-proof board, and it includes upper shell and lower house, described
Upper shell top is provided with axle sleeve；Described potentiometer main body includes that the carrier board being loaded with resistance, described carrier board are patty, and it sets
Put at above-mentioned housing bottom；Described resistance is fold-line-shaped circular ring structure, and it is arranged on described carrier board upper surface；Described carrier board
On be additionally provided with sliding contact, described sliding contact one end is fixed on described carrier board center, the other end by contact support
It is slidably connected with described resistance；The fixing end of described sliding contact is also connected with rotation bar, and described rotation bar passes described upper casing
Body top axle sleeve is also arranged 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 housing is connected by gluing with moist-proof board.
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 damp-proof 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；Recycling moist-proof board can be prevented effectively from outside wet
Gas invades inside potentiometer.
Accompanying drawing explanation

Fig. 2 is the potentiometer main body top view of the present invention.
Wherein, housing 1, upper shell 1-1, lower house 1-2, axle sleeve 1-3, moist-proof board 1-4, potentiometer main body 2, carrier board 2-
1, resistance 2-2, sliding contact 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 damp-proof potentiometer schematic cross-section of the present invention.A kind of damp-proof potentiometer, including housing 1
And the potentiometer main body 2 being arranged in housing 1；Described housing 1 uses cylindrical enclosed construction, and outer surface is provided with moist-proof board
1-4, it includes that upper shell 1-1 and lower house 1-2, described upper shell 1-1 top are provided with axle sleeve 1-3；Described potentiometer main body 2 is wrapped
Including the carrier board 2-1 being loaded with resistance 2-2, 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, and it is arranged on described carrier board 2-1 upper surface；It is additionally provided with slip on described carrier board 2-1 to touch
Point 2-3, described sliding contact 2-3 one end is fixed on described carrier board 2-1 center, the other end and institute by contact support 2-4
State resistance 2-2 to be slidably connected；The fixing end of described 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 is also 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.The moist-proof board 1-4 of the present invention can completely cut off the dampness in air and invade, and is prevented effectively from outside moisture and invades
Inside potentiometer.
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-
1 center of circle on the same line, thus ensure that the sliding contact 2-3 stability when being connected with resistance 2-2 bending part.This
Bright by rotate rotate bar 2-5 drive sliding contact 2-3 rotate on contact support 2-4, when sliding contact 2-3 with resistance
2-2 bending part utilizes the locating piece of contact support 2-4 upper surface and the locating slot button of sliding contact 2-3 lower surface when connecting
Closing fixing, convenient to use, stability is high.
Those of ordinary skill in the art it will be appreciated that embodiment described here be to aid in reader understanding this
Bright principle, it should be understood that protection scope of the present invention is not limited to such special statement and embodiment.This area
It is each that those of ordinary skill can make various other without departing from essence of the present invention according to these technology disclosed by the invention enlightenment
Planting concrete deformation and combination, these deform and combine the most within the scope of the present invention.
