In the present invention, described latch hook 10 is provided with the moving contact 101 of door contact switch, hook seat 20 is provided with the break back contact 201 of door contact switch, when latch hook 10 is in buckling state with hook seat 20, moving contact 101 and break back contact 201 closed communicating.

In the present invention, described latch hook 10 is also connected with the stay cord for manual unlocking or pull bar 70, in addition, described door cutter base plate 1 arranges stay cord leverage manual unlocking is carried out to car door lock.

The principle of work of the present embodiment is:

(1) as Fig. 3, shown in Fig. 4, layer door lock roller 30 is at cutting blade 21 and unlock between blade 31, when lift car is in flat bed region, door machine door opening process: transmission arm 41 abuts on door open limit block 32, now unlock blade 31 to conflict layer door lock roller 30, near positioning plate 43, with cutting blade 21 holding sheet door lock roller 30, the arc chute that track pad 33 is provided with or arc flange 331 promote unlocking arm 5, latch hook 10 rotates, latch hook 10 departs from the restriction of hook seat 20, moving contact 101 and break back contact 201 disconnect, car door lock is opened, layer door lock and car door lock are opened, door machine drives driving band 40, because transmission arm 41 has abutted against on door open limit block 32, so now transmission component 4, cutting blade 21, unlocking blade 31 can not relative motion, be equivalent to be fixed on a cutter base 1, driving band 40 driving gate cutter base 1, interlock layer door and gate, realize the synchronous unlatching of layer door and gate.

(2) door machine door closing procedure: after the little segment distance of enabling, the hook part 431 of positioning plate 43 positioning plate 43 end falls into the bayonet socket 411 on transmission arm 41, driving band 40 is closed the door in motion, transmission arm 41 is driven to be stuck on positioning plate 43, can reverse drive door cutter base, interlock layer door and gate close synchronously, when close to close the door end position time, pulley 60 on positioning plate 43 runs along guide plate 50, and positioning plate 43 is raised and departs from bayonet socket 411.When carrying out the preliminary activities of elevator up-down, driving band 40 drives transmission arm 41 to move, connecting rod 42 drives transmission arm 41, cutting blade 21 and unblock blade 31 are away from layer door lock roller 30, latch hook 10 is because fastening by gravity fall and hook seat 20, unlocking arm 5 promotes arc chute or the arc flange 331 of track pad 33, make unblock blade 31 and limiting stopper 32 separated by a distance, finally, transmission arm 41 abuts closes the door on limiting stopper 3221, layer door lock roller 30 does not contact with synchronous door knife, and lift car can up-downgoing campaign.

(3) when lift car is in flat bed region, in car or layer to open Door by Hand outdoors process: transmission arm 41 abuts on door open limit block 32, now unlock blade 31 to conflict layer door lock roller 30, near limiting stopper 32, with cutting blade 21 holding sheet door lock roller 30, the arc chute that track pad 33 is provided with or arc flange 331 promote unlocking arm 5, and layer door lock and car door lock are opened.Because transmission arm 41 has abutted against on door open limit block 32, transmission arm 41 is in the hinge-point of connecting rod 42 dead center position even crossing connecting rod 42 mechanism, this dead center position is that transmission arm 41 is as main driving, so now cutting blade 21, unlocking blade 31 can not relative motion, be equivalent to be fixed on a cutter base 1, synchronous door knife and layer door lock roller 30 mutually near, layer door and gate united opening can be realized.Therefore, work as Lift out of order, when being in flat bed region, can opening Door by Hand in car, or open the door outdoors from layer.

(4) when lift car is in non-flat layer region, conflict because there is no layer door lock roller 30 and unlock blade 31, unlock blade 31 separated by a distance with limiting stopper 32, latch hook 10 can not lift by arc chute or arc flange 331, and latch hook 10 still fastens with hook seat 20 under gravity, gate is in locking state, therefore under this situation, in car, manually can not push gate aside, stay cord or pull bar 70 can only be torn from sedan-chair, rotate latch hook 10, could unlock and realize gate unlatching.

Embodiment two:

As shown in Figure 8, the present embodiment is substantially identical with above-described embodiment one, and its difference is: two layer door lock rollers 30 are in cutting blade 21 and unlock blade 31 both sides, and limiting stopper 32 is at cutting blade 21 and unlock between blade 31, its operation logic is same as the previously described embodiments, does not repeat them here.

Embodiment three:

As shown in Figure 9, the present embodiment is substantially identical with embodiment one, and its difference is: on the base plate of latch hook 10, be provided with arching trajectory limit 102, and the unblock end unlocked on blade 31 is trip lever 5 ', in addition, also can conflict pulley be set on trip lever 5 ', to realize the object unlocked.The operation logic of this embodiment is substantially identical with above-described embodiment, does not repeat them here.

By description of listed embodiment, basic conception of the present invention and groundwork are set forth.But the invention is not restricted to above-mentioned listed embodiment.
