Abstract: A side-hung door device, a turnstile, and a control method therefor comprise a door leaf, a rotating shaft assembly connected to the door leaf, a brake assembly connected to the rotating shaft assembly, and a drive assembly configured to drive the door leaf to rotate and arranged on the turnstile, and the like. The brake assembly comprises an upper end portion connected to the rotating shaft assembly, and a lower end portion connected to the drive assembly. The drive assembly is electrically connected to the brake assembly. When the door leaf rotates toward a closed position and is subjected to an external force greater than or equal to a first preset value, the drive assembly stops driving the rotating shaft assembly, simultaneously, the brake assembly is powered on, and the lower end portion meshes with the upper end portion to brake the rotating shaft assembly.

Abstract: The objective of this application is to provide a switch device of a turnstile passage, consisting of a flap, a base, a frame, a guide rail mechanism arranged on the base and movably connected to the flap, a connecting rod swing mechanism 5 arranged on the frame 3, and a driving mechanism 6. One end of the connecting rod swing mechanism is rotationally connected to the flap so that the flap on the guide rail mechanism reciprocates between a closed position and an open position of the turnstile passage when the connecting rod swing mechanism swings; and the other end of the rod connecting rod swing mechanism is rotationally connected to the driving mechanism for driving the connecting rod swing mechanism to swing.
