by above-mentioned window or balcony or the external opening landing of building dressing good safety belt, certainly, for guaranteeing the speed of fleeing from, we can design simultaneously two people one or organize one group of three people or one group of many people descends simultaneously, allow again next group librarian use chain flee from landing after decline, when above-mentioned chain is the chain of circulation, so the user can constantly use the slow rope that falls of above-mentioned circulation, this has just played continuous lifesaving.above-mentioned technical scheme also has the following advantages: 1, can be provided with above-mentioned switch box body at each window of dwelling house and balcony, control stay cord or power-on switch, each window when breaking out of fire like this, the external opening of balcony and exterior wall is all passway for escaping, the people of premises communications centre specially crosses conflagration area and removes to seek specific passway for escaping, existing each family can not buy descending lifeline for each window, general one family can buy a descending lifeline or escape apparatus is just fine, so each family generally only has a descending lifeline passway for escaping, just may block escape personnel's escape when parlor or the breaking out of fire of doorway, bedroom, even if there is window on the escape personnel side, when descending lifeline in parlor or another room, but conflagration area has been blocked the escape personnel, therefore the escape personnel just can't take descending lifeline and go escape, and chain or chain that the application's technical scheme can be provided with circulation at each window and the balcony of every cover premises, all set up passway for escaping at each window and balcony, 2, now people to buy the quantity of descending lifeline few, main cause is to worry effect and the security performance of descending lifeline, if by the unified screening of developer descending lifeline, select superior in quality descending lifeline, that user will be more relieved, 3, the quantity that present people buy descending lifeline is few, reason also has the placement of descending lifeline to take up room, when using, descending lifeline will have fixedly part, the decorative effect that affect the room is understood in arranging of fixture, and the descending lifeline of the application's technical scheme is to be placed on the suitable parts such as roof or refuge story, it does not take the space of dwelling house, only needs the user during use from the window limit or chain that the lid of switch box body that the outside of body of wall is opened on the balcony limit just can be pulled out chain or circulation uses, 4, because the house type in the vertical direction of general dwelling house is the same, the window of every layer of dwelling house and balcony are unified in the position of vertical direction, so when descending lifeline is arranged on the building roofing layer or on refuge story the time, the chain of descending lifeline or the chain of circulation hang downwards to extend and just can satisfy the even all uses of floors of a plurality of floors, and developer's technical scheme of just implementing the application in the construction stage just reduces costs than each family's purchase descending lifeline like this, 5, by developer's unification, daily repair and maintenance work and the management work that descending lifeline also is convenient to descending lifeline is set, thereby guarantee the normal use of descending lifeline, 6, the user connects the fast and safety of the speed of the chain that uses chain or circulation during fire, the safety belt that descending lifeline only need dress need be installed and be connected and fixed chain or the chain of circulation jumps to fall to getting final product.one of advantage of the application's maximum also is: be at first because descending lifeline is arranged on roofing layer or refuge story, above-mentioned roofing layer or refuge story area are large, allow descending lifeline to be designed to the descending lifeline of large volume, can design the higher slowing-down structure of multiple protection in the inside large space due to the descending lifeline of large volume, this is that present family expenses small size descending lifeline can't be realized, also have descending lifeline or the escape apparatus of present family expenses also to exist usual detection all qualified, the accident but breaking out of fire just meets accident when using, this is that the user is fixed on descending lifeline by the other or balcony of window during due to breaking out of fire, at this moment fire-extinguishing truck is with regard to the floor room water spray of Chang Huixiang breaking out of fire, the frictional force that the injection that the descending lifeline of friction-type runs into water will reduce the descending lifeline internal structure makes slowly falls the speed that rope is drawn out of and causes the accident greater than safety speed, same when the room breaking out of fire, can outwards spray flare from window or balcony after fire spread, flame, this also can cause the above-mentioned damage that is fixed on the other or descending lifeline that balcony is other of window, lost efficacy, this is all the major safety risks that breaking out of fire uses present descending lifeline or escape apparatus to exist, adopt technique scheme just can evade above-mentioned potential safety hazard, this is because descending lifeline is arranged on roofing layer or refuge story, this is not ignition point, descending lifeline can not be subject to the impact of fire, when also having breaking out of fire, after the user has dressed safety belt and has been connected and fixed the chain of above-mentioned chain or circulation by window or balcony or outward opening is descended safely, due to the safety speed general control that descends 1 meter of per second---1.5 meters, that is to say that chain is to descend with interior speed with 1.5 meters of 1 meter of per second or per seconds, above-mentioned chain brushes fireproof paint, even at this moment slowly fall rope and be exposed in flame, because the effect of fireproof paint and the slow rope that falls are that speed with 1.5 meters of 1 meter of per second or per seconds is drawn out of and descends, the time that chain is in flame is very short, flame can not cause damage to chain, it is last that building is more and more higher now, the Super High building continues to bring out, this just causes the slow rope that falls of present descending lifeline constantly to lengthen, the volume of descending lifeline constantly increases, the model of descending lifeline also must constantly increase, this will inevitably affect descending lifeline manufacturing cost and practicality, and the application's technical scheme just can be evaded this problem, the application's technical scheme can be only offers each floor with the chain of a vertical chain from top to bottom or circulation and uses, no matter which floor breaking out of fire all can use above-mentioned that root to descend safely from the roofing layer of described building or the chain of the vertical fallen chain of refuge story or circulation.
