Positioning potentiometer

Abstract

The invention discloses a positioning potentiometer, which belongs to the technical field of potentiometers and comprises a potentiometer body, a knob, a mounting plate, a limiting column, a connecting disc, a compression spring, a shaft, a screw, a steel ball, an elastic cylindrical pin and a bolt. The potentiometer body is fixed on one side of the mounting plate, the shaft is connected with the other side of the potentiometer via the elastic cylindrical pin after penetrating through a longitudinal hole of the connecting disc, the steel ball and the compression spring are successively placed in a transverse hole of the connecting disc, the transverse hole of the connecting disc is communicated with the longitudinal hole, a groove is arranged on the shaft and corresponds to the steel ball, the screw penetrates through the spring to be connected onto the connecting disc, the knob is connected with the shaft, and the limiting column is fixedly connected with the connecting disc. The positioning potentiometer has the advantages that the rotation angle of the potentiometer is limited, rotation action out of a work range of the potentiometer is limited, the potentiometer rotates in the normal work range, and reliable and effective work of the potentiometer is guaranteed.

Description

technical field [0001] The invention relates to a positioning potentiometer, which belongs to the technical field of potentiometers. Background technique [0002] In the use of the potentiometer in the paver, it is enough to connect the potentiometer and the knob directly. The rotation angle of the potentiometer is 360 degrees, so during the use of the steering knob of the paver, the driver's grasp of the equipment , The sense of direction is not easy to grasp. One of the characteristics of the paver is to walk in a straight line, so the position of turning left, turning right, and zero position is not easy to grasp. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a positioning potentiometer, which limits the rotation angle of the potentiometer and is convenient for the driver to operate. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a po...
