Device adopting rotary shifting fork associated with action of outward unlocking mechanism to achieve emergency unlocking

Abstract

The invention provides a device adopting a rotary shifting fork associated with the action of an outward unlocking mechanism to achieve emergency unlocking. The device comprises the rotary shifting fork, a pull rope and the outward unlocking mechanism. The device is characterized in that one end of the rotary shifting fork is connected with the pull rope, the other end of the pull rope is connected with the outward unlocking mechanism, and a shifting fork is arranged at the other end of the rotary shifting fork; and when the rotary shifting fork receives the outward unlocking or inward unlocking action, a suction arm is lifted to be not engaged with a lock tongue any more through the cylindrical shifting fork. The device adopting the rotary shifting fork associated with the action of the outward unlocking mechanism to achieve emergency unlocking has the following advantages that the emergency unlocking function can be achieved reliably, limitation of the unlocking time is avoided, and as long as the rotary shifting fork receives the outward unlocking action, the emergency unlocking function can be achieved both in the front half period of the electric suction action and the rear half period of the electric suction action; and using is more convenient and safer, and the problem that according to a first-generation suction lock, a suction motor cannot complete the motor turning restoration action during suction of the suction motor or after suction is completed by the suction motor due to a sudden power failure, and consequentially a door lock cannot be unlocked is solved.
