The utility model discloses a
universal motor train unit hand-held sliding plug door rubber strip anti-
extrusion function measuring device, which comprises a hand-held terminal, one side of the hand-held terminal is provided with a fixed threaded hole, the inside of the hand-held terminal is fixedly connected with a sensor base, and one side of the hand-held terminal is provided with a single-
chip microcomputer installation limiting groove. According to the
universal motor train unit hand-held sliding-plug door rubber strip anti-
extrusion function measuring device, a hand-held terminal is placed on the edge of a sliding-plug door frame, then a sliding-plug door is closed, a sensor fast plug and a high-pressure block are extruded, and a high-precision S-shaped
pressure sensor is installed on a sensor base through bolts; the sensor can convert tiny deformation caused by
mechanical pressure when the anti-
extrusion rubber strip of the sliding plug door is activated into resistance change, then the resistance change is converted into accurate
voltage or current signals through the
Wheatstone bridge circuit and the
signal conditioning circuit, and a single-
chip microcomputer is installed in the single-
chip microcomputer installation limiting groove. According to the device, lean maintenance item points of the sliding plug door are effectively increased.
