Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, not
For limiting the present invention.
As shown in figure 1, the waterproof potentiometer schematic cross-section for the present invention.A kind of dust-proof potentiometer, including housing 1 and set
Put the potentiometer main body 2 in housing 1；Described potentiometer main body 2 includes the carrier board 2-1 being loaded with resistance 2-2, described carrier board
2-1 is patty, and it is arranged on above-mentioned housing 1 bottom；Described resistance 2-2 is fold-line-shaped circular ring structure, and it is arranged on described load
Body plate 2-1 upper surface；Sliding contact 2-3 is additionally provided with described carrier board 2-1, contact is passed through in described sliding contact 2-3 one end
Support member 2-4 is fixed on described carrier board 2-1 center, and the other end is slidably connected with described resistance 2-2；Described sliding contact 2-3
Fixing end be also connected with rotating bar 2-5, described rotating bar 2-5 is arranged in described housing 1 through described housing 1 top center
On heart axis, it is provided with closed loop groove one in housing 1 exterior section；Described housing 1 adopts cylindrical enclosed construction, its top
It is provided with closed loop groove two；Described housing 1 is provided with collar 1-1, described collar 1-1 medial wall with the junction of rotating bar 2-5
It is provided with closed loop projection one corresponding with described groove one, bottom is provided with closed loop projection two corresponding with described groove two.
