Its technical scheme is: mainly by sill latch adapter plate, trigger, the sill latch, the sill and the gap limiting groove that opens the door are formed, side-lower installs and fixes sill latch adapter plate in the door of the Room, flexibly connect trigger and sill latch on the sill latch adapter plate, sill at Room door is provided with and the corresponding gap limiting groove that opens the door of sill latch, one end of trigger fastens the sill latch, the other end connects Room external-open lock assembly by steel rope, fixing sill latch tension spring between the top of the tail end of described sill latch and sill latch adapter plate, described sill latch makes the front end of sill latch insert in the gap limiting groove that opens the door of sill under the pulling force of sill latch tension spring, makes Room door open the unpassable less gap of human body.
Above-mentioned sill latch adapter plate is fixed on the inboard of former Room every plate by sill latch adapter plate anchor shaft, and the bottom of sill latch adapter plate is provided with the sill latch movable axis that is used for fixing the sill latch; The middle part of described sill latch adapter plate is provided with the trigger anchor shaft that is used for fixing trigger.
Have the steel rope connecting bore on the left side of above-mentioned trigger, an end of steel rope passes in the hole; The middle part of described trigger connects sill latch adapter plate by the trigger spring; The bottom righthand side of described trigger is provided with sill latch locking mouth, flexibly connects with the sill latch.
It is spacing spacing with trigger that the middle part of above-mentioned sill latch adapter plate is provided with the sill latch.
On the above-mentioned Room door acoustic-optic alarm is installed.
The beneficial effects of the utility model are: owing to do not change original Room door, installs very simply, be convenient to transform in batches having elevator; 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, avoid taking place the outer floor personnel of elevator the danger that crashes into elevator hoistways is arranged, after confirming no safety hazard, open the new type of safe device again Room door is opened, carry out operation.
Four, description of drawings:
Accompanying drawing 1 is the structural representation of the utility model when not starting;
Accompanying drawing 2 is the working state structure scheme drawings after the utility model starts;
Among the last figure: sill latch adapter plate 1, trigger spring 2, trigger 3, sill latch 4, trigger anchor shaft 5, sill latch locking mouth 6, sill latch movable axis 7, sill latch are spacing 8, trigger is spacing 9, steel rope connecting bore 10, sill latch tension spring 11, steel rope 12, acoustic-optic alarm 13, Room external-open lock assembly 14, sill 15, the gap limiting groove 16 that opens the door, sill latch adapter plate anchor shaft 17 and 18, Room door 19 and 20.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
The utility model is mainly by sill latch adapter plate 1, trigger 3, sill latch 4, the sill 15 and the gap limiting groove 16 that opens the door are formed, side-lower installs and fixes sill latch adapter plate 1 in Room door 20, flexibly connect trigger 3 and sill latch 4 on the sill latch adapter plate 1, sill 15 at Room door is provided with and the sill latch 4 corresponding gap limiting grooves 16 that open the door, one end of trigger 3 fastens sill latch 4, the other end connects Room external-open lock assembly 14 by steel rope 12, fixing sill latch tension spring 11 between the top of the tail end of described sill latch 4 and sill latch adapter plate 1, described sill latch 4 makes the front end of sill latch 4 insert in the gap limiting groove 16 that opens the door of sill 15 under the pulling force of sill latch tension spring 11, makes Room door 19 and 20 open the unpassable less gap of human body.
Wherein, sill latch adapter plate 1 is fixed on the inboard of Room door 20 by sill latch adapter plate anchor shaft 17 and 18, and the bottom of sill latch adapter plate 1 is provided with the sill latch movable axis 7 that is used for fixing sill latch 4; The middle part of described sill latch adapter plate 1 is provided with the trigger anchor shaft 5 that is used for fixing trigger 3.
Wherein, have steel rope connecting bore 10 on the left side of trigger 3, an end of steel rope 12 passes in the hole; The middle part of described trigger 3 connects sill latch adapter plate 1 by trigger spring 2; The bottom righthand side of described trigger 3 is provided with sill latch locking mouth 6, flexibly connects with sill latch 4.It is spacing 9 that the middle part of sill latch adapter plate 1 is provided with sill latch spacing 8 and trigger, can control the actuating length of sill latch 4 and the actuating length of control trigger 3; Acoustic-optic alarm 13 is installed on original Room door 20.
The gap limiting groove 16 that opens the door is meant that lading door dill groove desired location leaves a limiting groove, and the Safe width that Room door is opened is redefined for the unpassable width of human body, promptly is not more than 10 centimeters.
During use, under the elevator normal operating condition, trigger catches on latch, the elevator door normal switch.Need manpower when open the door in the outside when running into extraordinary circumstances, triangular key is rotated, and at first touches the sound and light alarm chip, and verbal cue and light prompt are worked simultaneously, play the security warning effect.When key turns, former Room external-open lock assembly 14 and steel rope 12 are (certainly, also can adopt other linkages) upward movement, also upward movement thereupon of trigger 3 under the effect of pulling force, push rod 1 moves downward under the effect of gravity, in the gap limiting groove 10 that opens the door of the push rod 1 bottom insertion Room student's sill groove, Room external-open lock assembly 14 is with upwards pulling of steel rope 12, trigger 3 is also upward movement thereupon, and sill latch 4 moves downward under the effect of spring, and sill latch 4 front ends fall in the gap limiting groove that opens the door, door lock is lived, it is unpassable than small gap that elevator door is only opened human body, and when opening as needs, maintenance or rescue group must squat down again, pin sill latch 4 from the bottom, make its front end break away from the gap limiting groove 16 that opens the door, make trigger 3 catch on sill latch 4, door can be opened by the whole of safety.
