Abstract

Disclosed is an anti-pinch type translational turnstile, comprising a frame (20), an oscillating arm structure arranged on the frame, and a sensor (12). The oscillating arm structure is driven by a drive mechanism to oscillate such that the oscillating arm structure drives a gate plate (19) to translate in a sector shape. The oscillating arm structure comprises a driving oscillating arm (5) fixed to a driving end of the drive mechanism and a driven oscillating arm (6) connected to the gate plate (19) via a shaft. The driving oscillating arm (5) and the driven oscillating arm (6) are arranged in limited movement. When the gate plate (19) is blocked by an object, the drive mechanism drives the driving oscillating arm (5) and the driven oscillating arm (6) to move, and then the sensor (12) detects the displacement and controls the drive mechanism to stop operating or operate reversely. The anti-pinch type translational turnstile achieves the braking of an electric motor by mechanical shifting when an infrared fault occurs.
