Background technology
Existing door lock of elevator national standard, as GB, 7588 ?2003 specify: drive layer door in the situation that at gate, in the time that car is beyond onlocking zone, no matter layer door be because which kind of reason is unlocked, and all should have a kind of device can guarantee that layer door close automatically.Existing Room door suspension assembly is in the time of lift car leveling, and automatic door lock or lock body on the door cutter insert layer door on gate, make to follow gate to move together after hammerlock disengagement latch hook, must overcome in this case the gravity of spring or weight, increases the energy consumption of door motor.
Pass through the retrieval of prior art is found, Chinese patent literature CN201288007, discloses a day 2009.08.12, has recorded a kind of unlocking apparatus of door lock of elevator.On can be with the elementary cell of elevator door synchronized operation, be provided with the door cutter mechanism for matching with the door holder structure of door opening machine for elevator, on the S. A. of croquet mechanism, be coaxially connected with one and can rotate and be combined with retracing spring moveable lock hook with croquet mechanism, be provided with the fixed lock hook that an energy coordinates with the mutual hook of this moveable lock hook in the corresponding position of elevator door opening, moveable lock hook and fixed lock hook the two contact opposite end place respectively with making it enter the sliding bevel that adapts that hook coordinates, moveable lock hook is also also connected with a manual unlocking mechanism through operating structure simultaneously. and wherein this manual unlocking structure is arranged on the upper door frame of elevator door, the particularly lower portion place of upper door frame.But the aesthetic property that the prior art is just unblanked outward for elevator door, make people at elevator for can't see a layer door lock, required power can not reduce layer door and open time, reduces the energy consumption of door motor switch gate, reaches energy-conservation object.Utility model content
The utility model, for prior art above shortcomings, proposes a kind of unlocking mechanism of elevator landing door, can reach energy-conservation object.
The utility model is achieved through the following technical solutions, the utility model comprises: door cutter, time power apparatus, inhibiting device, latching device, two door rollers, attaching parts and lock framves, wherein: two door rollers are arranged at respectively the two ends of lock frame, lock frame is connected with lock shaft, door cutter is arranged on a machine and with gate plate and is connected, one end of latching device is connected with lock frame, and the other end matches with the attaching parts being arranged on inhibiting device, and inhibiting device is connected with time power apparatus.
Described door cutter is meshed with door roller in the time of elevator cabin flat level.
Described latching device comprises: lock shaft, jam plate and latch hook, wherein: one end of jam plate is connected with lock frame by lock shaft, the other end is connected with latch hook, match with the lockhole of elevator in the top of jam plate, trailing flank contacts with lock frame, the layer door gear base plate that lock shaft is arranged at elevator is connected, and the hook portion of latch hook matches with attaching parts.
One end and the inhibiting device of described attaching parts fix, and the other end has the groove structure matching with the hook portion of latch hook and the disconnecting prevention structure arranging obliquely.
Described inhibiting device comprises: limiting stopper and spacing ball, wherein: a side of limiting stopper is connected with time power apparatus, and opposite side is flexibly connected with spacing ball.
The described power apparatus that returns includes but not limited to that spring, weight or other can be realized and forces the mechanism of closing the door.
Technique effect
Compared with prior art, the utility model is at Elevator landing, door cutter engages with roller and while opening the door, is with moveable lock hook simultaneously,, make the attaching parts and the door lock assembly support that are connected with inhibiting device automatically-unhooked, when door cutter drives a Room door to open the door like this, just no longer need to overcome back the resistance of power apparatus, in the time that door cutter drives layer door door-closing in-place, this device will automatically reset again, ensure the safety of switch gate simultaneously; In the time of the key operated layer door of car external application, this device can be not automatically-unhooked, thereby make this device realize energy-conservation effect.

Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under taking technical solutions of the utility model as prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
As shown in Figure 1, the present embodiment comprises: door cutter (not shown), return power apparatus 1, inhibiting device 2, latching device 3, two door rollers 4, attaching parts 5 and lock framves 6, wherein: two door rollers 4 are arranged at respectively the two ends of lock frame 6, lock frame 6 is connected with lock shaft 7, door cutter is arranged on a machine and is connected on gate plate, when flat bed, be meshed with door roller 4, one end of latching device 3 is connected with lock frame 6, the other end matches with the attaching parts 5 being arranged on inhibiting device 2, and inhibiting device 2 is connected with time power apparatus 1.
Described latching device 3 comprises: lock shaft 7, jam plate 8 and latch hook 9, wherein: one end of jam plate 8 is connected with lock frame 6 by lock shaft 7, the other end is connected with latch hook 9, the top of jam plate 8 is connected with the lockhole of elevator, trailing flank is connected with lock frame 6, lock shaft 7 is arranged on the base plate of layer door gear of elevator, and the hook portion of latch hook 9 matches with attaching parts 5.
One end and the inhibiting device 2 of described attaching parts 5 fix, and the other end has the groove structure matching with the hook portion of latch hook 9 and the disconnecting prevention structure arranging obliquely.
Described inhibiting device 2 comprises: a side of limiting stopper 10 is connected with time power apparatus 1, and opposite side is flexibly connected with spacing ball 11.
Described attaching parts 5 is platy structure.
The working process of this device is as follows, and the power apparatus that returns in the present embodiment adopts spring to realize: when door cutter engages with roller 4 when opening the door, latch hook 9 also moves under the drive of lock shaft 7, throws off with attaching parts 5; At this moment spacing ball 3 can be stayed in limiting stopper 2 under the pulling force of spring 1, and door cutter drives the lock frame 6 on right side and supporting door strap to R.H.flapped door like this, just no longer needs to have overcome the resistance of spring.In the time that door cutter drives lock frame 6 door-closing in-place on right side, latch hook 9 contacts with attaching parts 5 and by the dislocation campaign of the disconnecting prevention structure that arranges the obliquely locking that automatically resets.When elevator is in non-flat layer state, people opens with key in the process of layer door outdoors at layer, and jam plate 8 rotates release with lock shaft 7, but latch hook 9 can't rotate along with lock shaft 7, and latch hook 9 can not break off relations with attaching parts 5, and layer door still can automatically reset in this case.
