Abstract
The invention provides a spiral type clutch return device based on double motor modules. The spiral type clutch return device comprises the double motor modules and a spiral type clutch return module. The risk that the work of the double motor modules is stopped when motors are damaged is lowered through the redundancy design that two same motors independently work, one motor is used and the other motor is used for standby application. The top end of a transverse shaft of a gear shaft is designed into a circular cone shape, the situation that A torsional spring wire is stuck with a transverse rod can not happen, and the torsional spring can return to the normal state. The spiral type clutch return module is arranged on an indoor rear face plate, and therefore when a front face plate is damaged and detached, a door block can still not be opened. The spiral type clutch return module can only rotate in a single direction; when the spiral type clutch return module rotates reversely, a square steel sleeve and an inner handle rotation piece are separated through spiral faces on the inner handle rotation piece and the square steel sleeve, the inner handle rotation piece can not be rotated through friction force, safety is high, and by means of the design, rapid locking can be conducted both indoors and outdoors.
