On another surface relative to cutting blade 21 swing mechanism 2 of door cutter base plate 1, described door machine transmission band 40 and transmission arm
41 is hinged, and described door cutter base plate 1 is provided with opening arcuate groove 11, and described connecting rod 42 one end is hinged on transmission arm 41, separately
One end is hinged on the first pivoted arm 22 or second pivoted arm 23 of a cutter, and described transmission arm 41 is placed in the pin joint of connecting rod 42
In opening arcuate groove 11；Described spring 44 one end is connected to a cutter base plate 1, and the other end connects transmission arm 41；
Fixing a guide plate 50 on described door machine bottom board, described limiting plate 43 end is provided with a hook part 431, described transmission
The end of arm 41 is provided with bayonet socket 411, and described hook part 431 can be conflicted with bayonet socket 411 and be coordinated, and can limit transmission arm 41
Rotational angle, described limiting plate 43 is provided with and matches to guide limiting plate 43 to depart from transmission arm 41 with guide plate 50
Pulley 60.
In the present invention, described door cutter base plate 1 is further fixed on door open limit post 12 and limited post 13 of closing the door, was opening the door
Cheng Zhong, one end of described transmission arm 41 is on door open limit post 12, at the pin joint of described transmission arm 41 and connecting rod 42
In or cross the position, dead point of connecting rod 42 mechanism being made up of the first pivoted arm 22 or the second pivoted arm 23, transmission arm 41 and connecting rod 42
Put；Closing door state, one end contact of described transmission arm 41 is being closed the door on limited block 32.Manually open in sedan-chair or outside stop
Men Shi, even if acting on the spring failure of transmission arm 41, transmission arm 41 still can abut against on door open limit block 32, it is ensured that just
Chang Gongneng.
In the present invention, described latch hook 10 is provided with the movable contact 101 of door contact switch, hook seat 20 is provided with door and touches
The stationary contact 201 of some switch, when latch hook 10 is in buckling state with hook seat 20, movable contact 101 closes with stationary contact 201
Close connection.
In the present invention, described latch hook 10 is also associated with the stay cord for manual unlocking or pull bar 70, additionally, described
On door cutter base plate 1, stay cord leverage is set car door lock is carried out manual unlocking.
The operation principle of the present embodiment is:
(1) as shown in Figure 3, Figure 4, layer door lock roller 30 is at cutting blade 21 and unlocks between blade 31, works as elevator
Car is in flat bed region, door machine door opening process: transmission arm 41 abuts on door open limit block 32, now unlocks blade 31
Conflict layer door lock roller 30, against limiting plate 43, with cutting blade 21 holding sheet door lock roller 30, track pad 33 is provided with
Arc chute or arc flange 331 promote unlocking arm 5, latch hook 10 to rotate, latch hook 10 departs from the restriction of hook seat 20, dynamic
Contact 101 disconnects with stationary contact 201, and car door lock is opened, and layer door lock and car door lock are opened, and door machine drives transmission band 40, because of
Transmission arm 41 has abutted against on door open limit block 32, thus now transmission component 4, cutting blade 21, unlock blade 31 can not
Relative motion, is equivalent to be fixed on a cutter base 1, transmission band 40 driving gate cutter base 1, linkage layer door and gate, real
The synchronization of existing layer door and gate is opened.
(2) door machine door closing procedure: after the little segment distance that opens the door, the hook part 431 of limiting plate 43 end falls into transmission arm 41
On bayonet socket 411, transmission band 40 close the door motion in, drive transmission arm 41 be stuck on limiting plate 43, can be with reverse drive door
Cutter base, linkage layer door and gate close synchronously, when close to close the door extreme position time, the pulley 60 on limiting plate 43 is along leading
Running to plate 50, limiting plate 43 is raised disengaging bayonet socket 411.When carrying out the preliminary activities of elevator up-down, transmission band
40 drive transmission arm 41 to move, and connecting rod 42 drives transmission arm 41, cutting blade 21 and unblock blade 31 away from layer door lock roller
30, latch hook 10 is because being fastened with hook seat 20 by gravity fall, and unlocking arm 5 promotes arc chute or the arc flange of track pad 33
331, make unblock blade 31 separated by a distance with limited block 32, finally, transmission arm 41 abuts limited block 3221 of closing the door
On, layer door lock roller 30 does not contacts with synchronous door knife, and lift car can be with up-downgoing campaign.
(3) it is in flat bed region when lift car, in car or layer opens Door by Hand process outdoors: transmission arm 41 abuts
On door open limit block 32, now unlock blade 31 and conflict layer door lock roller 30, against limited block 32, press from both sides with cutting blade 21
Holding a layer door lock roller 30, arc chute or arc flange 331 that track pad 33 is provided with promote unlocking arm 5, layer door lock and sedan-chair
Door lock is opened.Because transmission arm 41 has abutted against on door open limit block 32, transmission arm 41 is in very with the pin joint of connecting rod 42
To having passed past the dead-centre position of connecting rod 42 mechanism, this dead-centre position be transmission arm 41 as main driving for, so now moving
Blade 21, unlock blade 31 can not relative motion, be equivalent to be fixed on a cutter base 1, synchronous door knife and layer door lock roll
Wheel 30 mutually against, it is possible to achieve layer door and gate united opening.Therefore, work as Lift out of order, when being in flat bed region,
Can open Door by Hand in car, or open the door outdoors from layer.
(4) it is in non-flat layer region when lift car, unlocks blade 31 because not having layer door lock roller 30 to conflict, unlock blade
31 is separated by a distance with limited block 32, and latch hook 10 can not be lifted by arc chute or arc flange 331, and latch hook 10 exists
Still fastening with hook seat 20 under action of gravity, gate is in locking state, under the most this situation, it is impossible to manually take off in car
Open gate, 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 essentially identical with above-described embodiment one, and its difference is: two layer door lock rollers 30
Being in cutting blade 21 and unlock blade 31 both sides, limited block 32 is at cutting blade 21 and unlocks between blade 31, and its operation is former
Manage same as the previously described embodiments, do not repeat them here.
Embodiment three:
As it is shown in figure 9, the present embodiment is essentially identical with embodiment one, its difference is: set on the base plate of latch hook 10
There is arching trajectory limit 102, and unlocking the unblock end on blade 31 is trip lever 5 ', additionally, also can be in the upper setting of trip lever 5 '
Conflict pulley, to realize the purpose unlocked.The operation logic of this embodiment is essentially identical with above-described embodiment, at this no longer
Repeat.
By description of listed embodiment, elaborate basic conception and the ultimate principle of the present invention.But the present invention does not limits
In above-mentioned listed embodiment.
