Infrared through-beam sensor running counter

Abstract

The present invention relates to the technical field of running counters, and discloses an infrared through-beam sensor running counter, comprising a protective housing, wherein an infrared transmitting sensor is fixedly mounted on the left side of an inner cavity of the protective housing, and a receiver cooperating with the infrared transmitting sensor is fixedly mounted on the right side of the inner cavity of the protective housing; a rotating shaft is rotatably connected, by means of bearings, between the left and right sides of the inner cavity of the protective housing and is located below the receiver. The present invention, by providing the protective housing, the infrared transmitting sensor, the receiver, the rotating shaft, a flip plate, a balance block, a shielding plate and a digital display screen, enables convenient running counting; by providing a binding assembly, the device can be conveniently bound and worn on a knee or ankle region; and by providing a limiting plate, a first magnet and a second magnet, one-way magnetic attraction limiting of the flip plate can be achieved to prevent shaking. Through the arrangement of the above structures, running counting is facilitated, thereby satisfying user usage requirements.
