effect due to rotary body inertia, thereby human body just is subject to the effect of rotary body rotary inertia downwards and is subject to pulling force upwards while jumping at the beginning, we can and require the size design of safety speed to go out to have the rotary body of suitable rotary inertia according to the size of human body weight, that is to say that human body is subject to the effect of the rotary inertia of rotary body downwards while jumping, the initial decrease speed of human body is very little, then after starting to rotate, above-mentioned rotating disk reaches under the rotary body effect under the Action of Gravity Field at human body, what human body was subject to can become large downwards with joint efforts gradually, it is large that downward acceleration also can become gradually, it is large that the decrease speed of human body also can become gradually, at this moment descending lifeline can be had an effect and be made human body be subject to the slow pulling force that rope makes progress that falls, after descending lifeline plays one's part to the full, the human body decrease speed can reach more constant safety speed, this can produce the weightless fear sensation of bringing while just having solved the general descending lifeline of existing use.Also have, after adopting technique scheme, the described slow rope that falls can be hung along the outside of the exterior wall of building by controlling and extend to that the window of uppermost storey or intermediate floor is other or balcony is other or build that external opening is other provides use, during breaking out of fire, the user has dressed safety belt and has fallen that rope is fixedly connected with and by above-mentioned window or balcony or build external outward opening and land downwards with slow, thereby fall rope through the reducing gear of descending lifeline and be subject to the effect of reducing gear to guarantee that the slow rope that falls is drawn out with the speed of safety due to slow, this just can guarantee that the user descends with the speed of safety, when first user lands safely, second user can be connected to the safety belt of having dressed slowly to fall on rope by above-mentioned window or balcony or build external opening landing, 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 after decline next group librarian use is slow to fall rope and flee from landing, 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 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 find 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 the application's technical scheme can be at each window and the other slow rope that falls that all hung from top to bottom of balcony of every cover premises, all set up passway for escaping at each window and balcony, 2, the quantity that present people buy descending lifeline is few, and 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, during use, descending lifeline will have fixedly part, the decorative effect that affect room is understood in arranging of fixture, and the slow descending device 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 house, the lid that only needs the user to open the outside of body of wall or side or inboard switch box body from window limit or balcony limit during use just can start the rope releasing device and rope is fallen in slow on the roofing layer of described building or refuge story move to the outside of exterior wall release and delay and fall rope pulling and controlling stay cord or press power-on switch, the slow rope that falls just can extend to along hanging under the lateral of exterior wall by the opening that window is other or balcony is other or exterior wall is external of below floor, the user who needs like this escape slow falls that rope is fixedly connected with and jumping downwards falls with regard to wearable good safety belt by what grab rope device or adopt other way to put in place with above-mentioned extension, the user just can descend safely and escape under the effect that is arranged on the descending lifeline on roofing layer or refuge story, 4, because the house type in the vertical direction of general house is the same, the window of every layer of house and balcony are unified in the position of vertical direction, so when descending lifeline is arranged on the building surface layer or on refuge story the time, descending lifeline slow falls rope and hangs downwards to extend and just can meet the even all uses of floors of a plurality of floors, and the technical scheme that the developer just implements the application in the construction stage so just reduces costs than each family's purchase descending lifeline, 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 and uses the fast and safety of slow speed of falling rope during fire, and not needing to install descending lifeline only needs the safety belt of having dressed and be connected and fixed to delay to fall rope and jump 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 slowing-down structure that multiple protection is higher in the large space of the inside of the descending lifeline due to large volume, this is that current family expenses small size descending lifeline can't be realized, also have descending lifeline or the escape apparatus of current family expenses also to exist usual detection all qualified, the accident but breaking out of fire just meets accident while 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 to fall speed that rope is drawn out of and be greater than safety speed and cause the accident, 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 descending lifeline on window side or balcony side, lost efficacy, this is all the major safety risks that breaking out of fire is used current 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, while also having breaking out of fire, the user has dressed safety belt and has been connected and fixed above-mentioned hanging and extended put in place slow and fall after rope by window or balcony or outward opening is descended safely, due to the safety speed general control descended 1 meter of per second---1.5 meters, that is to say that the slow rope that falls is to descend with interior speed with 1.5 meters of 1 meter of per second or per seconds, the above-mentioned slow rope that falls adopts steel wire cable painting to brush fireproof paint, fall rope and be exposed in flame even at this moment slow, 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, it is slow that to fall the time of rope in flame very short, flame can not fall rope and causes damage slow, last building now is more and more higher, high-rise building continues to bring out, this just causes the slow rope that falls of current 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 can only offer each floor use with a vertical slow rope that falls from top to bottom, no matter which floor breaking out of fire all can be used above-mentioned that root to descend safely from roofing layer or the vertical fallen vertical slow rope that falls from top to bottom of refuge story of described building.When the application's descending lifeline adopts reciprocating descent control device and slow fall that rope adopts circulation slow while falling rope, from the extend out slow rope that falls of a volume circulation of descending lifeline, when executing agency move and discharge above-mentioned circulation slow while falling rope, the slow of circulation falls rope Crater face or approaches ground, therefore just there are two slow ropes that fall on the opening that window is other or balcony is other or exterior wall the is external side of the floor of executing agency below, above-mentioned two slow ropes that fall extend the slow rope that falls that is connected to become above-mentioned circulation, so above-mentioned two slow fallen the capable of circulation or user that alternately offer the floor of executing agency below of rope and use, certainly hang ground or while approaching ground of rope falls when above-mentioned circulation slow, preferably above-mentioned circulation slow the rope cover fallen to around arranging on the ground or on the runner on construction wall or rotating disk and tensioning.
