Above-mentioned latching device mainly is made up of latch spring, magnet coil and latch, magnet coil is fixed on the outer wall of door strap, the gap limiting groove that opens the door that latch passes on outer wall and the door guide rail locks Room door, between latch and magnet coil latch spring is installed.
The above-mentioned gap limiting groove that opens the door is arranged on 10 centimetres the position of opening the door on the guide rail, Room door can only open about about 10 centimeters and also human body unpassable than small gap.
One side of above-mentioned Room external-open lock assembly is installed the sound and light alarm chip, reminds the rescue group to take care.
Above-mentioned Room external-open lock assembly is installed in the below of hoistway door, and overhead about 10 centimetres, purpose is to make unlock staff's down-shift of working center, in case stop dropping into hoistway.
Reinforced rib is installed in the middle and upper part of above-mentioned hoistway door, and the skid plate of unblanking is installed on reinforced rib.
The beneficial effects of the utility model are: must squat down when unblanking, make down-shift of working center, to be opened to predetermined human body unpassable during than small gap when door, Room door is blocked, not only guarantee personal safety but also can observe situation in the elevator, avoiding taking place the outer floor personnel of elevator has the danger that crashes into elevator hoistways, opens the new type of safe device again after confirming no safety hazard Room door is opened, and carries out operation.
Four, description of drawings:
Accompanying drawing 1 is the structural representation of elevator when the utility model does not start when normally moving;
Accompanying drawing 2 is elevator working state schematic representations after the utility model starts when breaking down;
Accompanying drawing 3 is structural representations of Room door locking device;
Among the last figure: door unblank push rod 1, the skid plate 2 of unblanking, the skid plate movable axis 3 of unblanking, skid plate in the Room is flexible coupling and unblanks to be flexible coupling hole 6, sound and light alarm chip 7, Room external-open lock assembly 8, hoistway door 9 and 10, the movable latch hook 11 of Room door, door guide rail 12, Room door locking device 13, electric switch 14 outside hole 4, be flexible coupling steel rope 5, the Room; Door strap A1, door strap wheel A2, latch spring A3, magnet coil A4, latch A5, gap limiting groove A6 opens the door.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
The utility model comprises that door unblank push rod 1, the skid plate 2 of unblanking, the skid plate movable axis 3 of unblanking, skid plate in the Room is flexible coupling and unblanks to be flexible coupling hole 6, sound and light alarm chip 7, Room external-open lock assembly 8, hoistway door 9 and 10, the movable latch hook 11 of Room door and door guide rail 12 outside hole 4, be flexible coupling steel rope 5, the Room, described Room outward swinging door lock assembly 8 is installed in the below of a hoistway door, the skid plate 2 of unblanking is installed in middle and upper part at hoistway door, Room door locking device 13 is installed on the door strap of the Room, on the door guide rail 12 of Room door, is provided with latching device 13; One end of the described skid plate 2 of unblanking connects Room external-open lock assemblies 8 by the steel rope 5 of being flexible coupling, and the other end matches with Room door activity latch hook 11 by the Room door push rod 1 of unblanking, and the middle part of the skid plate 2 of unblanking is provided with the skid plate movable axis 3 of unblanking.
