Gate

Abstract

The invention relates to a gate which comprises a movable arm, a connector, a swing arm, a detector and a controller. The connector comprises a fixed part and a roller, the left end of the fixed part is horizontally clamped at the right end of the movable arm, and the roller is connected with the movable arm to move. The swing arm comprises a rotary end, the rotary end is clamped at the right end of the fixed part and can horizontally rotate in the fixed part, a polygonal groove is reserved along the left lateral edge of the rotary end, the roller is partially embedded in the groove and is tangent to at least one side wall of the groove, and when the rotary end horizontally rotate in the fixed part, the side walls tangent to the roller apply shear force to the roller and drive the movable arm to move leftward. The detector is used for detecting movement of the movable arm and sending signals after detecting the movable arm to move leftward. The controller is used for receiving the signals sent by the detector and controlling the movable arm, the connector and the swing arm to allow the swing arm to return to the original place after receiving the signals. By the gate, accidents can be avoided.

Description

technical field [0001] This application relates to channel facilities, and in particular to gates. Background technique [0002] Turnstiles can be widely used in subways, trains, automobiles and other transportation stations, tourist attractions and other places, and are currently the fastest and easiest means of access detection. At present, pedestrians or vehicles passing through the turnstile aisle are mainly detected by swiping card recognition to automatically move the swing arm, or manually operate the button to move the swing arm. However, in reality, it often occurs that the swing arm of the gate is collided without detection or for other reasons, which will not only cause damage to the gate, but also easily cause personal safety accidents. At present, this collision phenomenon can only be prevented by means of warnings and reminders. Once a collision really takes place, the accident is difficult to avoid.
