MULTI-POST OPERATION ESCALATOR AND MAVING WALK HEAD SENSOR TURN ROUND AN ANGLE REGULATION

摘要

A multi-post controlling the angle of a sensor is provided to detect accurately approach of people by controlling the angle of an infrared sensor according to installation place. In a multi-post controlling the angle of a sensor, a sensor fixing body is composed of a top cap(12), a rotation unit(13), and a bottom cap. An upper stopping protrusion is formed at an upper cap, and a lower stopping protrusion is formed at a lower cap. A circular ring of rotation unit is inserted into the upper protrusion and the lower protrusion. A guide groove is formed inside the upper and the lower cap and is joined with a coupling bolt. A fastening blot is assembled at a rigid frame. A gear is formed inside the rotation unit.
