Description
Technical field
The utility model relates to a kind of potentiometer, particularly relates to a kind of hollow potentiometer.
Background technology
Along with the future development of industrial automation towards 4.0, the demand of automation is increasing, the demand of transducer also increases day by day, wherein is no lack of tangent displacement sensor (potentiometer), traditional potentiometer carries rotating shaft, excessive height, bulky, use occasion has limitation, the occasion of narrow space cannot be applied, the hollow type potentiometer that volume is small cannot carry out potentiometric precision adjustment, cannot reach service precision requirement, makes some occasion cannot realize automation by the transmission of potentiometric effective accuracy analog signals.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of hollow potentiometer, and its volume is little, can carry out potentiometric precision adjustment, reach service precision requirement.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of hollow potentiometer, and it is characterized in that, it comprises lid, substrate, brush, type thing, axle sleeve, shell, lid is provided with the first through hole and the first projection, and substrate is provided with the second through hole, screwed hole, type thing is provided with third through-hole, fourth hole, second is protruding, and axle sleeve is provided with fifth hole, and shell is provided with the 3rd projection, perforate, fin, groove, 6th through hole, first through hole and the first projection are all positioned at the centre of lid, first projection is enclosed within third through-hole through after the second through hole, one end of brush is threaded with screwed hole, the other end of brush be positioned at fourth hole, second projection is between third through-hole and fourth hole, and second is protruding through fifth hole, perforate, the outer surface that the 3rd projection is positioned at shell is positioned at the outside of perforate, and groove is between fin and perforate, and the 6th through hole is through fin and be communicated with perforate, the diameter of the 6th through hole, the diameter of fifth hole is all less than the diameter of perforate.
Preferably, the side of described second projection is provided with step.
Preferably, the diameter of described third through-hole is less than the diameter of fifth hole.
Preferably, the diameter of described third through-hole is less than the diameter of the first through hole.
Preferably, the diameter of described third through-hole is less than the diameter of the second through hole.
Positive progressive effect of the present utility model is: the utility model hollow potentiometer volume is little, can carry out potentiometric precision adjustment, reach service precision requirement, can realize automation by the transmission of potentiometric effective accuracy analog signals.
Accompanying drawing explanation
