second user can be connected to the safety belt dressed and slowly to fall on rope by above-mentioned window or balcony or build external opening landing, certainly, for ensureing to flee from speed, we can design simultaneously two people one group or three people one group or many people one group and decline simultaneously, allow after decline next group librarian use is slow to fall rope and flee from landing again, this just plays the effect of continuous lifesaving.Above-mentioned technical scheme also has the following advantages: 1, house each window side or balcony side can be provided with above-mentioned built-in pipe from top to bottom, built-in pipe opening, delay and fall rope, each window so when a fire, balcony and the external opening of exterior wall are all passways for escaping, the people of premises need not cross conflagration area and goes to find specific passway for escaping by communications centre specially, 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, escape personnel's escape just may be blocked when parlor or the breaking out of fire of doorway, bedroom, even if escape personnel is other window, when descending lifeline is in parlor or another room, but conflagration area has blocked escape personnel, therefore escape personnel just cannot take descending lifeline and go escape, and the technical scheme of the application can be provided with from top to bottom to delay and falls rope in the built-in pipe that each window is other and balcony is other often overlapping premises, all passway for escaping is set up at each window and balcony, 2, people buy the quantity of descending lifeline seldom now, and main cause worries effect and the security performance of descending lifeline, if by developer's unified screening 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 fixing part, fixture the decorative effect that can affect room is set, and the slow descending device of the technical scheme of the application to be placed on the suitable part such as roof or refuge story, it does not take the normal usage space of building, the lid only needing user to open the outside of body of wall or the switch box body of side or inner side from window limit or balcony limit during use pulls out and above-mentionedly slow fall rope one or slowly fall rope two or rope falls in the slow of circulation in the opening of built-in pipe, such user that need escape by what grab rope device or adopt other way and above-mentioned extension to put in place with regard to wearable good safety belt is slowly fallen rope one or slow falls rope two or the slow rope that falls that circulates is fixedly connected with and jumps downwards, user just can decline safely and escape under the effect being 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 to be arranged on building surface layer or on refuge story time, the rope extended use that just can meet the even whole floor of multiple floor from the top down falls in the slow of descending lifeline, and the technical scheme that such developer just implements the application in the construction stage just reduces costs than each family purchase descending lifeline, 5, daily repair and maintenance work and the management work that descending lifeline is also convenient to descending lifeline is set by developer is unified, thus ensure the normal use of descending lifeline, 6, during fire, user connects and uses slow speed of falling rope fast and safety, does not need to install safety belt that descending lifeline only needs to have dressed and be connected and fixed to live in state to delay to fall rope jumping and fall.One of maximum advantage of the application is also: be first because descending lifeline is arranged on roofing layer or refuge story, above-mentioned roofing layer or refuge story area large, descending lifeline is allowed to be designed to the descending lifeline of large volume, the higher slowing-down structure of multiple protection can be designed in the inside large space of the descending lifeline due to large volume, this is that current family expenses small size descending lifeline cannot realize, the descending lifeline of current family expenses or escape apparatus is also had also to there is detection usually all qualified, the accident but breaking out of fire just meets accident when using, this is because user during breaking out of fire is fixed on descending lifeline by window side or balcony, at this moment fire-extinguishing truck is sprayed water with regard to the floor room 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 descending lifeline internal structure makes slowly to fall speed that rope is drawn out of and be greater than safe speed and cause the accident, same when room breaking out of fire, outwards flare can be sprayed from window or balcony after fire spread, flame, this also can cause the above-mentioned damage being fixed on the descending lifeline that window is other or balcony is other, lost efficacy, this is all the major safety risks that breaking out of fire uses current descending lifeline or escape apparatus existence, 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, user dressed safety belt and be connected and fixed above-mentioned from the top down extended slow rope falls and after by window or balcony or decline safely to outward opening, because the safe speed general control declined is at 1 meter per second---1.5 meters, that is the slow rope that falls declines with the speed within 1 meter or per second 1.5 meters per second, the above-mentioned slow rope that falls adopts steel wire cable or static(al) rope and is coated with and brushes fireproof coating, fall rope be exposed in flame even if at this moment slow, due to fireproof coating effect and the slow rope that falls is drawn out of with the speed of 1 meter or 1.5 meters per second per second and declines, it is slow that to fall the time that rope is in flame very short, flame can not fall rope and causes damage slow, last building is now 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 technical scheme of the application just can evade this problem, the application only can fall rope with vertical from top to bottom slow and be supplied to each floor and use, what no matter which floor breaking out of fire all can use that root above-mentioned to extend layout from top to bottom from the roofing layer of described building or refuge story slowly falls rope safety declines by the effect of above-mentioned descending lifeline.When the descending lifeline of the application adopts reciprocating descent control device and slow fall that rope adopts circulation slow when falling rope, fall rope from extend out circulation slow of descending lifeline and be extended in the built-in pipe in the outside of the inner or exterior wall of exterior wall from the top down, built-in pipe is provided with opening at each floor place, the slow rope that falls that user can pull out circulation in opening uses, and uses so rope user capable of circulation or that be alternately supplied to each floor falls in above-mentioned circulation slow.
