Dynamic door knife is flexibly connected, and the other end of second connecting rod is flexibly connected with the latch hook, the middle part of second connecting rod
It is flexibly connected with the door knife bottom plate；
The driven door knife is connected by the 3rd connecting rod with the door knife bottom plate, the both ends difference of the 3rd connecting rod
It is flexibly connected with the door knife bottom plate and the driven door knife；
The guide plate and the limiting plate are each attached on a machine bottom board, and the active door knife is provided with move portion；Institute
The one end for stating latch hook is connected by tension part with the active door knife, when gate is closed, the latch hook it is another
End hook is hung on the limiting plate, and the guide plate props up the move portion, and the active door knife is moved along the guide plate
Move to the position disengaged with layer door roller, it is in lift that the active door knife drives described latch hook one end by the tension part
State, the latch hook drive the driven door knife mobile and widen the spacing with the active door knife so that layer door roller can
Pass through between the active door knife and the driven door knife.
Preferably, the move portion is action roller, and the face that the guide plate can be in contact with the action roller is
Guiding surface, the guiding surface along gate close when door machine belt moving direction be inclined upwardly.
Preferably, the tension part is chain.
Preferably, the moving direction of door machine belt when being closed along gate, second connecting rod and the 3rd connecting rod
Parallel oblique is set up, and the position that second connecting rod is connected with the latch hook is higher than second connecting rod and the door
The position of knife bottom plate connection.
Preferably, the moving direction of door machine belt when being closed along gate, the 4th connecting rod tilts upward setting, described
The position that 4th connecting rod is connected with the active door knife is not less than the position that the 4th connecting rod is connected with the door knife bottom plate
Put.
Preferably, two the 4th connecting rods be arranged in parallel, two the 4th connecting rods and the door knife bottom plate
Tie point is on a vertical curve, and the tie point of two the 4th connecting rods and the active door knife is on one article of vertical curve.
Preferably, in addition to the first extension spring and the second extension spring, the both ends of first extension spring respectively with the active door knife
Connected with the door knife bottom plate, the both ends of second extension spring are connected with the driven door knife and the door knife bottom plate respectively, institute
It is extended state to state the first extension spring and second extension spring.
Preferably, one end that first extension spring is connected with the door knife bottom plate is less than first extension spring and the active
The connected one end of door knife, one end that second extension spring is connected with the door knife bottom plate be higher than second extension spring with it is described driven
The connected one end of door knife.
Preferably, second connecting rod passes through rotating shaft and the latch hook, the door knife bottom plate and the driven door knife
Formed and be flexibly connected；3rd connecting rod forms activity even by rotating shaft and the door knife bottom plate and the driven door knife
Connect；4th connecting rod is formed with the door knife bottom plate and the active door knife by rotating shaft and is flexibly connected.
The utility model achieves following technique effect relative to prior art：
When gate normal switching-off, in gate critical closing to during completely closed state, the activity on active door knife is rolled
Wheel moves upwards along guide plate, drives the 4th connecting rod to be rotated counterclockwise around the 4th connecting rod and the tie point of door knife bottom plate, makes
Active door knife away from driven door knife, drive active door knife pull open with driven door knife distance, and disengaged with layer door roller, work as sedan-chair
When door completely closes, active door knife makes tension part be tension, so as to which active door knife pulls latch hook to lift by chain, latch hook
Drive the second connecting rod to be rotated counterclockwise around the second connecting rod and the tie point of door knife bottom plate, make driven door knife away from active door
Knife, the spacing with active door knife is widened, now, active door knife and driven door knife do not contact with layer door roller, above and below car
During operation, the space that layer door roller can be between active door knife and driven door knife passes through, and layer door roller is prevented taking off a knife with elevator
It will not be interfered with each other between device.
When being opened the door in flat bed region, door machine, which rotates, drives the movement of door machine belt, so as to pull head rod, the first connection
Bar drives gate to open.When gate is opened, active door knife moves downward along guide plate, drives the 4th connecting rod around the 4th connecting rod
Rotated clockwise with the tie point of door knife bottom plate, loosen active door knife chain between driven door knife, active door knife and latch hook,
Latch hook first falls, and latch hook drives the second connecting rod to be rotated clockwise around the second connecting rod and the tie point of door knife bottom plate, makes driven
For door knife close to active door knife, the layer door roller for the layer door lock being now placed between active door knife and driven door knife is pressed against driven door
Knife, gate are continued on, and driven door knife will be made to be compressed active force by layer door roller and moved downward, and band moveable lock hook lifts,
And latch hook is remained lifting status, disengaged with limited block so that gate can be opened；Layer door roller is driven simultaneously
Under the squeezing action power that door knife is given and the layer gate stop lock of layer door lock is opened, layer door is in the state that can be opened, then
The elevator normal door under the drive of active door knife and driven door knife.
When opening gate in non-leveling zone domain, gate hanging plate moves to enabling direction, and chain loosens, and latch hook falls, and drives
Active door knife and driven door knife are close to each other, and because non-leveling zone domain does not have the setting of layer door roller, now driven door knife is not
Compressed power by layer door roller, also not by other active forces, latch hook can not just lift, thus catch on limiting plate, prevent gate after
It is continuous to open, reach the anti-purpose taken off.
