Abstract
The invention discloses a sealed type potentiometer. The sealed type potentiometer comprises a shell and a potentiometer main body arranged in the shell, wherein the shell adopts a cylindrical sealed structure, and a shaft sleeve is arranged on the top of the shell; multiple annular sealing grooves are formed in the inner wall of the shaft sleeve; and matched annular sealing rings are arranged in the sealing grooves. According to the sealed type potentiometer provided by the invention, by setting a resistor into a folded line structure, the maximum value of the resistor is effectively improved; by enabling a sliding contact to be connected with a bending part of the resistor, different precisions of the potentiometer can be set according to the bending quantity and degree of the resistor, so that convenience in use is improved; and in addition, by virtue of the sealing rings, the good sealing property of the sealed potentiometer is ensured, and the operational performance of the potentiometer is guaranteed.

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 closed type potentiometer schematic cross-section for the present invention.A kind of closed type potentiometer, including housing 1
And it is arranged on the potentiometer main body 2 in housing 1；Described housing 1 adopts cylindrical enclosed construction, and its top is provided with axle sleeve 1-1；
Described axle sleeve 1-1 inwall is provided with multiple annular seal grooves 1-2, is provided with, in described sealed groove 1-2, the annular matching
Sealing ring 1-3；Described potentiometer main body 2 includes the carrier board 2-1 being loaded with resistance 2-2, and described carrier board 2-1 is patty, its
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 carrier board 2-1 upper surface；
Sliding contact 2-3 is additionally provided with described carrier board 2-1, described sliding contact 2-3 one end is fixed on by contact support 2-4
Described carrier board 2-1 center, the other end is slidably connected with described resistance 2-2；The fixing end of described sliding contact 2-3 also with rotation
Bar 2-5 connects, and described rotating bar 2-5 passes through described upper shell 1-1 top axle sleeve 1-3 and is arranged on described housing 1 central axis
On.
The present invention passes through to arrange sealed groove 1-2 and the O-ring seal 1-3 that matches so that potentiometer has preferably
Sealing property is it is ensured that potentiometer has preferably serviceability.Preferably, O-ring seal medial surface indention, further
Enhance the sealing property of potentiometer.
As shown in Fig. 2 potentiometer main body 2 top view for 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 is uniformly or non-uniformly bar shaped, in 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
