The utility model provides a kind of emergency escape door, and a kind of emergency escape door, comprising: doorframe; On doorframe, be provided with hinge, on hinge, being provided with can be around the shop front of hinge through folding; In shop front inner side, be provided with the downslide mechanism outwards hanging from above when the shop front is opened; On doorframe, be provided with and when the shop front is opened, make the shop front stay open the supporting mechanism of state.

Due to downslide mechanism being set in the shop front, reached the object of withdrawing rapidly highrise building when emergency.

Below in conjunction with the specific embodiment, realization of the present utility model is described in detail.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, be the schematic diagram of the first emergency escape door of providing of the utility model, a kind of emergency escape door, comprising: doorframe 4; On doorframe 4, be provided with hinge, on hinge, being provided with can be around the shop front 1 of hinge through folding; In the shop front 1 inner side, be provided with the downslide mechanism outwards hanging from above when the shop front 1 is opened; On doorframe 4, be provided with and when the shop front 1 is opened, make the shop front 1 stay open the supporting mechanism 2 of state; Opening of emergency escape door can be manual, also can be automatic, if just need automatically the pick-up transducers of installation environment parameter (as temperature, smog, humidity, harmful gas concentration etc.), whether acquisition parameter by relatively deciding emergency escape door to open with setting value in control module; Control module and the sensor that gathers ambient parameter can be made of one with emergency escape door, so just facilitate standardized production; Certainly the sensor that gathers ambient parameter can be also to separate with emergency escape door; When emergency escape door is opened, as the downslide mechanism of life-saving, just need to outwards hang from above, downslide mechanism can be exactly the most simply a rope, as long as it is just passable to guarantee down to slide into ground, but just needs safer downslide mechanism for women and children the old and the weak; When emergency escape door is opened, the shop front of emergency escape door should be fixed, so just can not disturb downslide, so need supporting mechanism 2 that the shop front 1 is supported, make the shop front folding angle of emergency escape door keep fixing.

Further, as shown in Figure 1, Figure 2, Figure 4 shows, downslide mechanism is constant speed downslide cucurbit 7, and adopting constant speed downslide cucurbit is the scheme of comparative maturity, the gliding speed of constant speed downslide cucurbit 7 can be adjusted into and allow women and children the old and the weak feel not fear, when contacting to earth, does not damage and is advisable; The cucurbit body of constant speed downslide cucurbit 7 can directly hang over the inner side of the shop front 1 as shown in Figure 1, Figure 2, Figure 4 shows, the body of wall inner side that also can hang over the top of doorframe 4 or emergency escape door is installed, is drawn chain 5 hang down from the position, inner side of the shop front 1 by fixed pulley; So just can slide into down safely and reliably ground.

Further, as shown in Figure 1, Figure 2, Figure 4 shows, also comprise the buckle-up 6 on the chain 5 that is arranged on cucurbit 7; Buckle-up 6 is that series connection is arranged on the more than one buckle-up 6 on chain 5; Buckle-up 6 is dismountable buckle-ups 6; Buckle-up 6 can adopt existing latching device the people who glides reliably padlock on buckle-up 6, adopt series connection that the quantity that can increase downslide people is set, instantly slide into behind ground again the doorway that buckle-up 6 is withdrawn into emergency escape door and need the time, if high-rise words, buckle-up 6 retracts like this and may just just have little time to continue escape at all, so can be dismountable; First be ready to the buckle-up 6 of sufficient amount in room, while needing like this, buckle again on chain 5, so just can realize series connection escape; So the intensity of the intensity of emergency escape door, the intensity of hinge and supporting mechanism all needs to be designed to abundant people and glides and could meet the needs that series connection is glided simultaneously.

Further, as shown in Fig. 3, Fig. 5, downslide mechanism comprises the lifting rope 9 being arranged in the shop front 1, and lifting rope 9 is wrapped on two rollers 8, and two rollers 8 link together by support; Thisly by two rollers 8, lifting rope 9 is wrapped on two rollers 8, while being added with weight on support, lifting rope 9 is wound around just tightlyer on two rollers 8, the frictional force of lifting rope 9 and two rollers 8 also increases like this, rolling speed also can correspondingly reduce, the speed offset that the speed that just can realize weight like this when gaining in weight and frictional force reaches balance increases is reduced by frictional force, thereby just realize the function that constant speed glides, if frictional force is inadequate, can also be by increasing roller diameter or increasing the equilibrium relation that number of rollers guarantees weight and frictional force; The benefit that adopts this two-wheel mechanism is to slide into ground under people, there is no weight on support, and frictional force has also just reduced, and two rollers 8 can be withdrawn into rapidly to the doorway of emergency escape door like this, to again glide; This roller downslide mechanism can be for the floor of bottom comparatively, the pull-back speed of this mechanism is faster than the constant speed cucurbit that glides simultaneously, this is that its return speed is also certain because the speed ratio of cucurbit is certain; And idler wheel mechanism frictional force when non-loaded is less, pull-back speed is just than comparatively fast.

Further, as shown in Fig. 3, Fig. 5, also comprise the buckle-up 6 being arranged on support; Buckle-up 6 is dismountable buckle-ups; This is that the same series connection that can guarantee is glided with above-mentioned cucurbit as the principle of downslide mechanism; But the series connection quantity of idler wheel mechanism should not be too much, this is to have operated with regard to bad because the extension of how having connected is taken the nethermost roller in position; If the inside roller design to the shop front 1, adopts duplex type sagging, also can reach constant speed downslide object.

Further, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, supporting mechanism 2 is hydraulic push rod or air-leg or pull bar or collapsible steel frame; Supporting mechanism 2 can adopt existing structure, as long as the shop front 1 can be fixed while guaranteeing to open, and intensity to reach requirement just passable.

Further, as shown in Figure 1, also comprise the safety barrier 3 for preventing from falling being arranged in doorframe 4 when the described shop front 1 is opened; In case of emergency, people are generally more flurried, if at this moment on high building, people can make that people is timid, leg is soft fearing high pressure, so the installation of safety barrier 3 is just necessary, so just can first rest on safety barrier 3, the buckle-up 6 that is suspended on outside is withdrawn in room, has been with buckle-up 6, then stride across safety barrier 3 downslides, particularly, for women and children the old and the weak, such design just can be safer.

Further, as shown in Figure 1, Figure 2, Figure 3 shows, hinge is arranged on doorframe 4 tops; Emergency escape door is exactly upper and lower folding like this, and hinge at this moment, door and supporting mechanism all need sufficient intensity; At this moment downslide mechanism can be directly installed on the shop front 1 inner side as shown in Figure 2 and Figure 3; Also can be arranged in doorframe 4 or even in room, then by the fixed pulley of installing in the shop front 1 inner side, downslide chain or rope guiding outwards also outwards be hung from above.

Further, as shown in Figure 4, Figure 5, hinge is arranged on doorframe 4 sides; At this moment emergency escape door is exactly opening and closing left and right; At this moment higher to the requirement of strength of hinge and door; Downslide mechanism can be directly installed on the shop front 1 inner side equally; Also can be arranged in doorframe 4 or even in room, then by the fixed pulley of installing in the shop front 1 inner side, downslide chain or rope guiding outwards also outwards be hung from above.

When preferably, the shop front is opened, the distance of buckle-up 6 and doorframe 4 is 15 to 100cm; This can carry out specific design according to people's brachium, and in general, 20cm is proper distance for most people; Be exactly in addition when the building number of plies is many, install emergency escape door towards the identical situation towards position that there will be the installation of different layers, at this moment, in order to make the escape non-interference of upper and lower floor, can allow downslide mechanism adopt the distance of different outside suspensions to solve this problem, like this, even same towards position, the distance that different layers stretches out is different, just can reach non-interference object.

In a word, the utility model, by adopting constant speed down slide device, safety barrier and down slide device to set with the distance of doorframe when opening, makes different floors energy when emergency is escaped safe and reliable, does not interfere with each other.

The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
