Abstract
The invention discloses a floating rod potentiometer. The floating rod potentiometer comprises a protective shell, an oil pipe, a floating rod and a resistor body, wherein the oil pipe is fixedly arranged at the center of the bottom in the protective shell; the bottom of the oil pipe is closed, the upper end of the oil pipe is open, and hydraulic oil is filled into the oil pipe; the floating rod is arranged at the center of the protective shell; the upper end of the floating rod stretches out of the protective shell and the lower end of the floating rod stretches into the oil pipe and is immersed into the hydraulic oil; the floating rod is further sleeved with a positioning ring; a positioning rod is arranged on the outer side of the positioning ring; one end of the positioning rod is fixedly arranged on the positioning ring and the other end of the positioning rod is fixedly arranged on the inner side wall of the oil pipe; a conductive ring is further arranged above the positioning ring; the conductive ring is fixedly arranged on the floating rod; an electric brush is arranged on the outer side; one end of the electric brush is fixedly arranged on the positioning ring and the other end of the electric brush is contacted with the lower surface of the resistor body; the two ends of the resistor body are fixed by a supporting rod which is fixedly arranged on the inner side wall of the protective shell. According to the floating rod potentiometer, buoyancy force is used for replacing previous spring elastic force to press the electric brush on the resistor body so that the lack of the elastic force is not worried and the floating rod potentiometer is durable.
Description
Technical field
The present invention relates to technical field of electronic components, relate in particular to a kind of fly rod potentiometer.
Background technology
Potentiometer is a kind of conventional electronic devices and components, be widely used on the by-pass cock of various electric equipments, potentiometer inside is in the market mechanical structure completely, normally the elastic force by spring is against brush on resistive element, year in and year out, along with the decline of spring force and disappearance brush probably produce loose contact with resistive element, cause current potential adjusting to go wrong.
Summary of the invention
the invention provides a kind of fly rod potentiometer, for prior art defect, adopt fly rod design to replace traditional spring.
Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of fly rod potentiometer, it is characterized in that: comprise containment vessel, oil pipe, fly rod, resistive element, described oil pipe is fixed on containment vessel inner bottom part center, hydraulic oil is equipped with in oil pipe bottom lock upper end open and inside, fly rod is arranged on containment vessel center, stretch out outside containment vessel fly rod upper end, lower end is stretched in oil pipe and is submerged in hydraulic oil, on fly rod, also cover has locating ring, the outside of locating ring is provided with backstay, one end of backstay is fixed on locating ring, the other end is fixed on oil pipe madial wall, the top of described locating ring is also provided with conducting ring, conducting ring is fixed on fly rod, the outside of conducting ring is provided with brush, one end of brush is fixed on locating ring, the other end and resistive element lower surface contact, the two ends of resistive element are fixed by the support bar being fixed on containment vessel madial wall.
Preferably, described fly rod is comprised of adjusting rod and ball float, and ball float is arranged on the bottom of adjusting rod.
Preferably, described resistive element is semicircle annular.
Preferably, below, described resistive element two ends is also provided with limited post.
Preferably, inside oil pipe, hydraulic oil surface is provided with one deck diaphragm seal.
The fly rod upper end of preferably, stretching out outside containment vessel described in it is characterized in that is provided with spacing ring.
The beneficial effect that the present invention reaches is: the design by oil pipe and fly rod replaces original spring, by buoyancy, replaces original elastic force, does not worry that the aging flexibility missing of spring causes the loose contact of brush and resistive element, and durable in use, stability is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In order to further describe technical characterstic of the present invention and effect, below in conjunction with the drawings and specific embodiments, the present invention is described further.
With reference to Fig. 1, a kind of fly rod potentiometer, comprise containment vessel 1, oil pipe 2, fly rod, resistive element 5, described oil pipe 2 is fixed on containment vessel 1 inner bottom part center, hydraulic oil 6 is equipped with in oil pipe 2 bottom lock upper end open and inside, fly rod is arranged on containment vessel 1 center, stretch out outside containment vessel 1 fly rod upper end, lower end is stretched in oil pipe 2 and is submerged in hydraulic oil 6, the top of fly rod is adjusting rod 3, bottom is ball float 4, the ball float in hydraulic oil 64 is not given buoyancy making progress of whole fly rod, on fly rod, also cover has locating ring 9 to be used for preventing fly rod double swerve, the outside of locating ring 9 is provided with backstay 10, one end of backstay 10 is fixed on locating ring 9, the other end is fixed on oil pipe 2 madial walls, the top of described locating ring 9 is also provided with conducting ring 7, conducting ring 7 is fixed on fly rod, the outside of conducting ring 7 is provided with brush 8, one end of brush 8 is fixed on locating ring 9, the other end is pressed on the lower surface of resistive element 5 under the effect of buoyancy at ball float 4, the two ends of resistive element 5 are fixing by the support bar 11 being fixed on containment vessel 1 madial wall.
With time can stretch out fly rod upper end outside containment vessel 1 by rotation and drive brush 8 mobile current potential that regulates on resistive element 5; for convenient, regulate; resistive element 5 is arranged to semicircle annular; in order to prevent that inordinate rotation fly rod from causing the disengaging of brush 8 and resistive element 5; below resistive element 5 two ends, be also provided with limited post 12; in order to prevent that hydraulic oil 6 from leaking; in oil pipe 2 inner side hydraulic oil 6 surfaces, be provided with one deck diaphragm seal 14; in order to prevent that fly rod is pressed in containment vessel 1, described in the fly rod upper end of stretching out outside containment vessel 1 be provided with spacing ring 13.
Above-described embodiment does not limit the present invention in any form, all take to be equal to replace or technical scheme that the form of equivalent transformation obtains, within all dropping on protection scope of the present invention.
