Working principle:
(1) realization of electric opening function: the motor is placed on lock body, the worm screw when motor reversion, on motor
Worm gear rotation is driven, and worm gear drives driving gear to be rotated clockwise (this is to rotate forward).When driving gear rotates clockwise
When, band moving cam rotates, and cam linkage driving handle connecting rod is moved towards direction shown in the direction 1 in Fig. 3, by driving handle
Connecting rod drives pawl release lever, and one end of pawl is inserted into the U-type groove of pawl release lever, to be discharged by pawl
Handle drives pawl is disengaged outwardly, such as state A in Fig. 3, to realize open function.And pawl one is disengaged, cam
Middle position is automatically reset to by reset spring immediately, motor mid level switch checks whether it returns to middle position.
(2) from the realization for being attracted function: when motor reversion, the worm screw on motor drives worm gear rotation, and worm gear drives
Driving gear is rotated (this is reversion) counterclockwise.As shown in figure 5, the snap-gauge is in the open state, when driving gear is inverse
When hour hands rotate, band moving cam rotates, and cam linkage connecting rod is moved towards direction shown in the direction 2 in Fig. 4, thus by connecting
Bar pushes snap-gauge to rotate counterclockwise towards shown in Fig. 4, i.e. engagement direction, meanwhile, shown in Fig. 5, snap-gauge pushes door knob switch
Handle is touched, touching handle is switched by door knob and presses door knob switch, whether detection snap-gauge is at a fully engaged, closes to realize from actuation
The function of door.And snap-gauge one is at a fully engaged, cam automatically resets to middle position by reset spring immediately, and motor mid level switch checks it
Whether middle position is returned to.
