The application relates to the technical field of three-roller gates, in particular to a
tail-following prevention three-roller gate, which comprises a
machine core, mounting tables, a three-pronged roller, a card swiping device, double
doors and induction motors, the mounting tables are oppositely arranged together and have intervals between the two mounting tables, the
machine core is installed in one of the mounting tables, the three-pronged roller is installed on the
machine core, the card swiping device and the machine core are installed on the same mounting table, the card swiping device is located at one end of the mounting table, the card swiping device is electrically connected with the machine core, the induction motors are respectively installed at one end of the two mounting tables away from the card swiping device, the output ends of the two induction motors face upwards, the double
doors are respectively fixedly connected to the output ends of the two induction motors, the
induction motor signal is connected with the card swiping device, the height of the double
doors is about 1.6-1.8 meters, one side of the double doors close to the card swiping device is provided with an
infrared sensor, and the
infrared sensor
signal is connected with the
induction motor, so that the purpose of preventing some users from arbitrarily crossing the three-roller gate without rules is achieved.
