Reverse position be provided with the extension spring being fixed on security window.
The operation principle of the technical program is：
The unlatching of security window：Tapered end from locking device is opened with keys such as triangles in car, or from outside car
With locking device tapered end is pushed aside manually, locking device tapered end can touch electronic security(ELSEC) checking switch normally closed safety when opening is touched
Point so that contact disconnects, the action of contact passes to apparatus for controlling elevator to cut off elevator operating loop by control signal wire,
Contact cannot rebound automatically, can only go manual reset by qualified person；Promote security window by blade-rotating to car
Security window is opened in outside, and is pushed into extreme position, and security window is opened and completed.It is whole in the presence of extension spring after security window is opened
Individual locking device is in idle initial bit, now when security window is closed downwards because of misoperation, the lock of locking device
Hook can hinder the abnormal closure of security window.
The closing of security window：Locking device is opened with keys such as triangles from car, or is dialled manually from car external application
Open locking device, promote security window by loose-leaf to closed safe window in car, after closing in place rotating and rotary locking in place, in extension spring
In the presence of, pressure house plate positioning rotation locking is closed, after the completion of locking device is closed, manually the normal of electronic security(ELSEC) checking switch
Closed contact reverses reset, and security window is closed just to calculate and completed after checking safety contact to recover in place by apparatus for controlling elevator.Electronics
Safety switch can effectively evade this potential safety hazard of burst accident in rescue operations using hand-reset mode.
Preferably, described car top safety switch be with normally-closed contact and can only hand-reset electronic security(ELSEC) checking open
Close.
Preferably, being provided with the stopper slot of rotation lock, the spacing channel opening and tension spring tension of pressure house plate in described pressure house plate
In the opposite direction.Pressure house plate carries out positioning limitation to the operating point position of rotation lock, and when rotation lock is located at locked position, the pulling force of extension spring is auxiliary
Rotation lock is helped to keep locked state.
Preferably, described rotation lock is provided with unlatching lockhole towards the side in car.Rotation rotation lock, makes tapered end depart from car top
Safety switch, you can open.
Preferably, there is described tapered end the raised double end in intermediate recess both sides to latch.There is easily positioning to be difficult what is disengaged
Feature.
Preferably, there is described tapered end the low single head in one side another side high to latch.Can equally realize locking work.
Preferably, one end of described extension spring is fixed on extension spring seat board, extension spring seat board is located at pressure house plate and revolves lock
Between articulated section.When ensureing rotation lock in open mode, rotation lock will not automatically reset.
Preferably, the locking termination of described car top safety switch inclines towards rotation lock opening direction.Apply locking termination
Power is towards extension spring direction, it is ensured that even if slightly vibrations rotation lock during car proper motion also will not easy disengagement.
The beneficial effects of the utility model are：Rotation lock and car top safety switch are mutually fastened, by the pulling force of extension spring, in hand
Dynamic when pushing locking device aside, car safety switch is off all the time, and contact cannot rebound automatically, can only be by qualified
Personnel manually could reply, it is to avoid security window occur because car surprisingly caused by the lock hook phenomenon that releases and open, it is ensured that
Staff and the safety of elevator operation；Effectively prevent the thing that caused by contact adhesion contact cannot be produced by effective action
Therefore；Simple structure, flexible movements, it is high that rotation is locked in the lower reliability of extension spring effect.

Specific embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Referring to Fig. 1, a kind of lift safety window locking device of the present embodiment sets lock in the middle part on the one side of security window 1
Device is closed, the another side of security window is connected by hinge with car, car top safety switch 2 is using band normally-closed contact and can only be manual
The Electronic safety switch checking of reset.
Specifically as shown in Figure 2 and Figure 3, a secondary triangle rotation lock 6 is installed on security window 1, rotation lock 6 is provided with locking bar, rotation lock 6
Locking bar end have with car top safety switch 2 locking termination coordinate locking tapered end 61, rotation lock 6 and car top safety switch 2 it
Between be provided with pressure house plate 3, rotation lock 6 opening direction reverse position be provided with extension spring 5, extension spring 5 is fixed on extension spring seat board 4, extension spring
Seat board 4 is fixed on security window 1, and extension spring seat board 4 is located between the articulated section of pressure house plate 3 and rotation lock 6；Rotation is provided with pressure house plate 3
The stopper slot of lock 6, the spacing channel opening of pressure house plate 3 is opposite with the direction of pull of extension spring 5.
Rotation lock 6 is provided with triangle and opens lockhole towards the side in car, in order to open safety using triangulation chain from car
Door.
The locking bar of rotation lock 6 is provided with long waist shaped hinge hole 62, and is provided with and be connected with extension spring 5 and extension spring hole 63, a kind of implementation
Example：Tapered end 61 has the raised double end lock in intermediate recess both sides, as shown in Figure 4.
Another embodiment of the locking bar of rotation lock 6：Tapered end 61 has the low single head lock in one side another side high, i.e., single angle rotation
Lock 7, as shown in Figure 5.
When installing car top safety switch 2, its locking termination inclines 10 degree of angles towards rotation 6 opening direction of lock.
When using, security window is opened：Rotation lock 6 is opened with triangle key, it is also possible to manual from car external application from car
