Technical field
The present invention relates to a kind of sliding door unlocking mechanism more particularly to a kind of manual solutions on metro safety sliding door
Except the mechanism of its locking.
Background technology
In order to ensure the safety of passenger, it can install semi high safety door system additional by the platform close to underground railway track and will wait
Platform is separated with track, and this safety door system uses a kind of sliding door, after vehicle, which arrives at a station, to come to a complete stop, is slided by electric automatic control
Dynamic door is opened, so as to passenger getting on/off.When vehicle is leaving from station, sliding door can be automatically closed it is sealed, in order to avoid the passenger that waits is strayed into rail
Road and cause unnecessary injury.If meeting emergency, semi high safety door system circuit is cut off, and sliding door cannot be automatic
Open, usually there is provision of it is a set of can release the sealed spare mechanism of sliding door manually, with ensure passenger withdraw it is safety.
It is equipped with releasing the sealed retaining mechanism of sliding door manually on the fix driving door of subway half-height safety door system,
When dodge gate is closed, retaining mechanism effectively locks dodge gate, prevents passenger from arbitrarily opening dodge gate, in rail side and platform
Side passenger and platform should be able to unlock rapidly, open dodge gate, it is ensured that passenger safety.Because usual door lock is mounted on dodge gate and admittedly
Determine the position of driving gate overlapping, existing hand-operating unlocking mechanism is that perpendicular type designs.Such as a Patent No. ZL200520063055.3
Disclose a kind of hand-operating unlocking mechanism for half high safety dodge gate of subway, the mechanism is by a rigid member by the pendulum at both ends
Movable plate connects, wherein the adjutage of left side oscillating deck and vertically-mounted button connects, right side oscillating deck adjutage with it is vertical
The mandril connection of installation, which is laterally set in the upper door frame of dodge gate, and the upper end of mandril is caused to correspond to sealed dodge gate
Lock core.When upward button press by the linkage of above-mentioned component, mandril can be made to move up the lock of the sealed dodge gate of top pressure
Core, it is sealed so as to release.Although the unlocking mechanism can be used for emergency manual unlock, but by a large amount of test, exist as follows
Defect：1st, cantilever lift hand unlock, have to be unlocked with the upward top pressure button of finger finger, at the same also need to another hand come
Push-and-pull is opened the door, and inconvenience is exerted oneself；2nd, rigid member and wobble plate composition unlocking mechanism, have the shortcomings that volume is big, heavy, are not easy to erect
To installation；If the 3, unlocking mechanism is damaged, disassembly process more complicated is not easy to replace, and therefore, it is necessary to existing manual unlocking
Mechanism is further improved.
Invention content

Technical solution is used by the present invention solves above-mentioned technical problem：The Manual unlocking device of sliding door, including setting
Put the lock body on door face board is slided and the handle on lock body, it is characterised in that：A confession is provided in the middle part of the handle
The mounting hole that lock body passes through, the head of handle is hinged on by axis pin to be slided on door face board, and the head of the handle is also by this
Axis pin is hinged with can be relative to the reciprocating locking bar of doorframe lock core, when the handle tail lifts rotation, the locking bar
Free end can stretch out doorframe and move up the lock core for pressing on doorframe, so as to fulfill the unlock of sliding door, and work as handle tail
When portion is put down, the free end of the locking bar can move down disengaging in the lock core of doorframe, so as to fulfill the locking of sliding door, this
Outside, the free end of the locking bar is provided with when sliding door is in locking state so that the locking bar free end has de- always
First connecting portion and second connecting portion are formed with from the end of the elastic component of doorframe lock core trend, the handle head, it is described
Axis pin is fixed between first connecting portion and second connecting portion, and correspondingly, the end of the locking bar forms the fork in inverse u shape
Mouthful, in the prong inserting in the state of the axis pin, the locking bar can be connected to the head of handle.Herein, the first connection
Hole is provided in portion and second connecting portion, axis pin is plugged on hole, during installation, it is only necessary to which prong inserting is dismantled on axis pin
When one pull out, do not need to complicated connecting component, it is simple in structure.
The locking bar is provided through the connecting rod of locking bar, and be supported in the connecting rod below neighbouring free end
First plate washer, and the free end of the locking bar is constrained on the second plate washer for being set to doorframe, second plate washer has for locking
Bar stretches out the through-hole outside doorframe, and is provided with the elastic component in the first plate washer and the accommodation space of the second plate washer formation.The bullet
The setting of property part so that the free end of locking bar can move upwards released with top pressure lock core it is sealed, when putting down handle, in elasticity
Under the action of the elastic reset of part, entire locking bar resets, and locking bar also returns to initial position.
Consider from cost and property angle easy for installation, preferably, the elastic component is a compressed spring, compressed spring
One end connects first plate washer, and the other end is connected to second plate washer.
The adjusting head that can be rotated along locking bar periphery wall is provided on the free end of the locking bar, to adjust the freedom of locking bar
Doorframe length is stretched out at end.The progressive error of lock core, the adjusting set on the free end of locking bar are stretched into order to compensate for the free end of locking bar
Head can be adjustable with its spinning in and out, to meet the requirement of the lock core interface of different locks.
Compared with prior art, the advantage of the invention is that locking bar is driven to act with the handle of lock body linkage so that lock
The free end of bar presses on the lock core of doorframe as the rotation of lock body moves up, and so as to fulfill the unlock of sliding door, has knot
Structure is simple, installation and convenient disassembly, the characteristics of interlocking strength is high, in addition, the present invention is using handle linkage of unlocking equipment mechanism, behaviour
Power needed for author is reduced, and sets solution lock body in sliding door platform side, can be opened sliding door by key, be facilitated work people
Member participates in rescue, and other people can be prevented to open by mistake, you can rail side and platform side respectively can be real by release lever and key
Existing manual unlocking, with the characteristics of highly practical, easy to operate.
