Between be provided with distance.Being provided with two parallel and spaced layer door lock rollers on the layer door lock 9 of described layer every boatswain chair should
Two layer door lock rollers can enter the position between left swing bar 71 and the right fork 73 of described door cutter 4 when Elevator landing, wherein
One is fast pulley 91, and another is driving wheel 92.
The operation principle of manual unlocking device outside the detailed description below elevator cage door lock of the present invention Room:
(1) as it is shown in figure 1, when elevator is at leveling zone, elevator power failure, rescue personnel needs to enter car and rescues people, and now two
Layer door lock roller i.e. fast pulley, 91 and driving wheel 92 enter in the region between left swing bar 71 and the right fork 73 in Men Dao 4 district, behaviour
When making, after first opening layer door one segment distance with triangular key interposed layer door triangulation chain, at observation car behind this layer of position, continue
Continuing and open layer door, now layer door lock fast pulley 91 will move together in company with layer door, and gate keeps static；
(2) when fast pulley 91 continues horizontal movement to the left, by contact door cutter 4 on left swing bar 71 and promote left swing bar 71 around
The axle center of left support rod 72 rotates counterclockwise, and left swing bar 71 drives top driving lever 75 to make around top-supported bar 76 axle center simultaneously
Rotating counterclockwise, top driving lever 75 is also hinged around left swing bar 71 while the axle center around top-supported bar 76 rotates counterclockwise
Portion rotates, and it has a horizontal motion components to the left during rotating, and this horizontal movement power be enough to stir the vertical of latch hook 51
Bar portion 512 rotates counterclockwise, makees unlocking motion, then, makees to turn counterclockwise around left support rod 723 axle center at left swing bar 711
After dynamic certain angle, when latch hook 10 lifts completely, i.e. the snap fit of latch hook main body 511 be separated from the lock-bit O on lock 6 (as
Shown in Fig. 2)；
(3) as it is shown on figure 3, left swing bar 71 will touch backing pin 8, being stopped by backing pin 8, left swing bar 71 no longer rotates, then
Promoting backing pin 8, backing pin 8 just drives door cutter 4 together with gate to left movement, it is achieved the action of enabling, thus completes elevator
The door opening process of car door lock manual unlocking device.
Embodiment two:
The present embodiment is essentially identical with embodiment one, and its difference is: as shown in Figure 6, and described solution lock set 7 includes a left side
Fork 71, left support rod 72, right fork 73, right support rod 74, top-tensioned stay cord 75 ', described top-tensioned stay cord 75 '
One end is fixed on left swing bar 71, and the other end is fixed on the vertical rod portion 512 of latch hook 51；Card in described latch hook main body 511
Hooking described left swing bar 71 when disengaging with the lock-bit on lock 6 and touch backing pin 8, it is drawn by top-tensioned stay cord 75 '
Action band moveable lock hook main body 511 upper clamping hook and the locking of lock 6 and the purpose of unblock, other operation principles are complete with embodiment
Identical, do not repeat them here.
The invention is not limited in above-mentioned embodiment, if to the various changes of the present invention or modification without departing from the spirit of the present invention
