Abstract:
    This is a spring control lifting mechanism. The mechanism is fixed on a guiding soleplate via a long tension spring, and the other end of the long tension spring is connected to a bracket on a supporting plate. The long tension spring drives the bracket to elevate, and the supporting plate is connected on a minor arc hinged plate. The minor arc hinged plate is fixed on a stopping plate which is fixed on the bracket. The bracket cooperates with the guiding soleplate and roll upwards and downwards via a bearing, and the falling extreme position of the bracket is limited by the stopping plate and is locked by a lock hook. The lock hook is controlled by the electromagnet or a suspension link, and a bunting pin is fixed on the stopping plate. The bunting pin has an effect on the blocking supporting plate when synchronously falls following the stopping plate, and a spring post pin accomplishes the requirement of stretching and contracting inside the guiding hole on the supporting rack of the ticket box following the action of the blocking supporting plate. The fixed limiting rack is fixed on the supporting rack of the ticket box, and the quick limiting rack is hinged with the fixed limiting rack.
