Abstract
The invention discloses a sealing dustproof potentiometer which comprises a lower shell and an upper shell.A shaft sleeve is arranged on the top of the upper shell, a first dustproof ring, a graphite sealing ring and a second dustproof ring are arranged on the inner surface of the shaft sleeve, and a cavity is formed between the lower shell and the upper shell.The cavity is internally provided with a rotary shaft, a conductive rotary piece, a first fixed pin, a second fixed pin, a movable pin and an arc resistor.The rotary shaft is matched with the shaft sleeve and comprises a metal core and a graphite outer layer, and the first fixed pin and the second fixed pin are connected to the two ends of the arc resistor respectively.In this way, triple sealing and dust prevention are conducted on the sealing dustproof potentiometer, sealing performance is good, and outside dust and moisture can be effectively prevented from entering the potentiometer.
Description
Technical field
The present invention relates to potentiometer field, particularly relate to a kind of sealing and dustproof potentiometer.
Background technology
Potentiometer be there are three exits, resistive element that resistance can regulate by certain Changing Pattern, potentiometer is generally made up of resistive element and moveable brush.Potentiometer is installed in the enterprising enforcement use of various equipment, plays adjustment effect, existing rotational potentiometer poor sealing performance, and sealant expansion character is poor, causes that dust, steam etc. enter inside potentiometer, can reduce the service life of potentiometer.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of sealing and dustproof potentiometer, it is possible to carry out triple seal dust-proof, good seal performance, it is possible to effectively prevent external dust, dampness from entering inside potentiometer.
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is: provide a kind of sealing and dustproof potentiometer, it is characterized in that, including: lower house, upper shell, described upper shell top is provided with axle sleeve, described axle sleeve inner surface is provided with the first dust ring, carbon seal ring, second dust ring, a cavity is formed between described lower house and upper shell, described cavity inside is provided with rotating shaft, conduction revolving fragment, first fixed pin sheet, second fixed pin sheet, dynamic pin sheet and circular arc resistance body, described rotating shaft matches with described axle sleeve, described rotating shaft includes metal inside and non-graphite outer layers, the first described fixed pin sheet and the second fixed pin sheet are connected to the two ends of circular arc resistance body.
In a preferred embodiment of the present invention, the first described dust ring is PTFE dust ring.
In a preferred embodiment of the present invention, described carbon seal ring material is expanded graphite.
In a preferred embodiment of the present invention, the second described dust ring is PTFE dust ring.
