More Information
Summary:The utility model discloses a chance hinders the bounce-back breaker, including a bounce-back controller and an ejector pin, the ejector pin fix on the door plant of rolling slats door, said bounce-back controller includes a magnetic switch and a micro-gap switch, and the magnet subassembly of magnetic switch is fixed in the gatepost bottom of rolling slats door, and the tongue tube and the micro-gap switch of magnetic switch are connected rolling slats door the control unit and integrated on a circuit board respectively, and the circuit board is fixed on the floorbar of rolling slats door. The ejector pin touch micro-gap switch to send the ascending signal of rolling slats door through rolling slats door the control unit, when the magnet subassembly is sensed to said tongue tube, send rolling slats door closed signals by rolling slats door the control unit. Application range is wide for the device, reaction sensitivity, reliable, the security that improves the electric roller shutter door greatly.
