Description
One, affiliated technical field
The present invention relates to the two joint elongations of a kind of folding chair formula and open the earthquake open-air evacuation ladder automatically, especially in moment at stake in several seconds is arrived in earthquake, this room outside escape ladder be the shortcut oblique angle away from building, when arrival open-air evacuation stair hypomere, actual danger alleviates.
Two, background technology
Because people lack knowledge to the origin of earthquake, difficulty can be made accurate forecast before violent earthquake is arrived, cause earthquake to cause a tremendous loss of lives, the Wenchuan violent earthquake is exactly a miserable example, Beichuan county according to the severely afflicated area is obvious and clear, begin slightly to rock the time weak point of building collapse in the current violent earthquake from the face of land, the personnel that live and handle official business at high building do not have the enough time to flee from all, wrecked common people's great majority are to be crushed to death in evacuating the way, part the dead has gone to downstairs ladder way and has been murdered, only differed from for one to two second, this each miserable sight can't help to make the people to feel sad.Consequently, people urgently wish to have a kind of the evacuation in the way in earthquake just can obtain than safety means.
Three, summary of the invention
For solving people in earthquake arriving shortcut evacuation fast in a flash, the present invention seeks to design a kind of folding chair formula two joint elongations and open the earthquake open-air evacuation ladder automatically, this escape ladder is that the room external staircase is gone downstairs at the shortcut oblique angle again, the harm of building collapse is compared alleviate.
For achieving the above object, the solution that the present invention takes is: the earthquake open-air evacuation ladder is opened in a kind of folding chair formula two joint elongations automatically, it is by an imminent earthquake alarm buzzer, transfer and slow down cylinder, slowing down descends pins down rope, escape ladder upper end tracks, the track cover moves up and down, folding chair formula open-air evacuation main staircase glides and stretches out ladder, but the folding active column, folding column two end axles, main escape ladder railing glides and stretches out ladder rail, railing axis of rotation, escape ladder draws high the rope rotating disk, escape ladder draws high hawser, and escape ladder is put a buckle automatically, and compositions such as stretching out terraced drag-line glides.
Feature and advantage of the present invention are, one, this folding chair formula open-air evacuation ladder it implement by the control of imminent earthquake alarm buzzer, can open automatically in the imminent earthquake very first time.Two, it be with the shortcut oblique angle away from building, make and evacuate the common people and leave desperate situation ahead of time.Three, usually, escape ladder is the vertical attitude of awaiting orders outside the folding chair formula room, and it does not take up space and does not block traffic.Four, escape stair is to fall from top to bottom in force outside this folding chair formula room, does not need to add in addition power and implements.Five, because the enforcement of folding chair formula open-air evacuation ladder is to fall from top to bottom, also be the program of opening egress door automatically in the decline process, so that needn't establish loaded down with trivial details safety door again.

Five, the specific embodiment
The following basis accompanying drawing of awaiting orders remakes description in conjunction with the implementing procedure legend to the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the earthquake open-air evacuation ladder is opened in a kind of folding chair formula two joint elongations automatically, comprises setting an imminent earthquake alarm buzzer (1), puts a buckle (15) automatically for the control escape ladder and implements.Folding chair formula open-air evacuation main staircase (6) is established a downslide again and is stretched out ladder (7) and two downslides and stretch out ladder and draw high rope (16) in the ladder.Folding chair formula open-air evacuation main staircase (6) but the middle part connects downwards two folding active columns (8) and folding column two end axles (9), for supporting open-air evacuation main staircase (6) but weight folding effect again.Folding chair formula open-air evacuation main staircase (6) upper end is established two and is slowed down to descend and pin down rope (3) and one and transfer and slow down cylinder (2), controls folding chair formula open-air evacuation main staircase (6) and descends in certain speed.Two escape ladders upper end tracks (4) and two track covers (5) that move up and down are established in both sides, folding chair formula open-air evacuation main staircase (6) upper end, folding chair formula open-air evacuation main staircase (6) energy freely be opened and can folding.Folding chair formula open-air evacuation main staircase (6) upper end establishes in addition that two escape ladders draw high hawser (14) and an escape ladder draws high rope rotating disk (13), draws high the position of the attitude of awaiting orders etc. for folding chair formula open-air evacuation main staircase (6).
Referring to Fig. 5, folding chair formula open-air evacuation main staircase (6) top is provided with main escape ladder railing (10), the top that ladder (7) is stretched out in downslide also is provided with to glide stretches out ladder rail (11), and each railing all has railing axis of rotation (12), ejects when implementing nearly to finish and turns over to vertical attitude.
When folding chair formula open-air evacuation main staircase (6) when awaiting orders attitude, it leans against high building wall limit with vertical in form, but also has covered the doorway of escape ladder, guarantees that egress door does not meet with an accident.
When the earthquake arriving face of land began slightly to rock, imminent earthquake alarm buzzer (1) had also been opened the control escape ladder and has been put a buckle (15) automatically when giving the alarm.So beginning to glide, outwards opens folding chair formula open-air evacuation main staircase (6), in the way that descends, pin down the restraining function of rope (3) because of being subjected to transferring slowing down cylinder (2) and slowing down to descend, folding chair formula open-air evacuation main staircase (6) upper end can only be descended in suitable speed.Gradually descend because of folding chair formula open-air evacuation main staircase (6) upper end simultaneously, making glides stretches out two of ladder (7) upper end and draws high rope (16) and increase, stretching out ladder (7) so glide also just progressively stretches out downwards, when treating that folding chair formula open-air evacuation main staircase (6) is implemented to finish nearly, main escape ladder railing (10) and downslide are stretched out ladder rail (11) and are popped up and turn over to vertical.All implementation procedures consequently finish, and flee from for like this evacuation personnel fast with the shortcut oblique angle.
