Abstract

The invention discloses a telescopic vent type building-fire indoor life-saving device used for indoor lifesaving of people in building fire. When the building fire happens, if the inside can still be isolated from outside naked flame besides being permeated with toxic gas and smoke and/or poor in oxygen, and when risk for escaping from windows or doors is higher, no better methods for lifesaving in scenes of fire of the kind exist in the prior art, and the problems can be solved through the device. A telescopic vent set in more than two stages is formed by means of sleeving a small-diameter tube in a large-diameter tube, and a partial overlap section is formed between the mutually sleeved tubes; through the partial overlap section, on the basis of respective original tube diameters, the large-diameter tube shrinks, the small-diameter tube expends, and a quite small same matched taper angle is formed between the large-diameter tube and the small-diameter tube, and accordingly self-locking and connection are ensured to be tight without falling down. One end of a vent is communicated with outside air, and the other end of the vent is connected with a breathing joint to allow indoor people to breath.

Description

The indoor lifesaving appliance of telescopic vent formula building fire
Technical field
Patent of the present invention discloses the indoor lifesaving appliance of a kind of telescopic vent formula building fire, relates to the indoor lifesaving appliance in the fire-fighting of relevant building fire.
background technology
When the building fire occurs, if indoor still can air lock except only penetrating into toxic gas, flue gas and/or anoxic outer naked light, and larger from the danger of window or door escape, lifesaving for this class scene of fire, the method that prior art there is no, be trapped in indoor personnel and seal mouth and nose (anoxic is uncertain available) except the towel kind fabric with wet and reduce toxic gas and suck waiting for rescue with time expand and there is not yet better device.Individual other indoorly has emergency oxygen gas cylinder (comprising joint for respiratory device or face shield etc.) class available, but obviously general building do not possess this condition.
the patent of invention content
In order to solve still unsolved this class fire indoor occupant lifesaving difficult problem of above-mentioned prior art, patent purpose of the present invention is to provide a kind of lifesaving appliance that is exclusively used in indoor occupant in this class building fire.
Patent of the present invention is to adopt following technical proposals to realize:
The indoor lifesaving appliance of telescopic vent formula building fire, comprising: joint for respiratory device; It is characterized in that: form telescopic breather pipe external member more than two-stage by heavy caliber pipe box small-bore pipe, a local overlay segment is arranged between the pipe be nested.Described local overlay segment is that this part overlay segment pipe is being expanded wherein large-aperture pipe contraction, small-bore pipe to make to form each other identical cooperation tapering or draft angle on original mouth of pipe bore basis separately.Nose end maximum in described breather pipe external member connects joint for respiratory device, the logical outside atmosphere of minimum nose end.
The accompanying drawing explanation
Fig. 1 is the structural representation of patent of the present invention.
1. small-bore pipes in figure, 2. large-diameter pipe, 3. overlay segment, 4. joint for respiratory device.
The specific embodiment
For technological means, creation characteristic that patent of the present invention is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with accompanying drawing 1 and specifically preferred embodiment patent of the present invention is described further.
Referring to accompanying drawing 1, the indoor lifesaving appliance structure of the present embodiment telescopic vent formula building fire is very simple.Its selects that bore is close but unequal, section can be justified can be just, the applicable indoor several sections pipes (hop count of pipe is according to indoor placement space condition, and general 2 to 3 sections get final product) of laying at ordinary times length; Large-diameter pipe 2 cover small-bore pipes 1 are formed to telescopic breather pipe external member more than two-stages, the suit overlay segment 3(of a part is arranged for the sake of simplicity between the pipe respectively be nested, accompanying drawing has only been drawn the breather pipe external member that two sections pipes only have an overlay segment 3).Each overlay segment 3 wherein large-aperture pipe contraction, small-bore pipe on the bore of the primary tube separately basis of this part overlay segment pipe expand and make it be each other very little identical cooperation tapering or draft angle, can rely on the Small Taper of two pipe overlay segments 3 to coordinate the larger frictional force of generation to come self-locking to hold two pipes tightly, not only can block small-bore pipe 1 deviates from outside large-diameter pipe 2, also can stop small-bore pipe to shrink back voluntarily, overlay segment 3 also can adopt other multiple known interconnection technique certainly.Nose end maximum in the breather pipe external member connects joint for respiratory device 4, the logical outside atmosphere of minimum nose end.For heatproof and fire prevention, wherein outdoor section pipe adopts metal material relatively good.General rubber or the plastic productions of adopting of joint for respiratory device 4() press known technology with being connected of the maximum mouth of pipe more.
When the building fire occurs, still can intercept the naked light of outside except only penetrating into toxic gas, flue gas and/or anoxic as indoor, and when larger from the danger of window or door escape, at this moment indoor occupant can be as using telescopic antenna, each relatively little small-bore pipe of telescopic vent is pulled out step by step and lead to the outdoor place that fresh air is arranged, put on joint for respiratory device and breathed, wait for rescue.
Obviously, Patent equipment of the present invention is easy-to-use, is simple and easy to system, practicality, with low cost, is easy to generally promote, and can create more the chance of rescue life.
Above demonstration and described the advantage of basic principle, principal character and the patent of the present invention of patent of the present invention.The technical staff of the industry should understand; patent of the present invention is not restricted to the described embodiments; the principle that patent of the present invention just is described of describing in above-described embodiment and specification; under the prerequisite that does not break away from patent spirit and scope of the present invention, patent of the present invention also has various changes and modifications, and these changes and improvements all fall in claimed the scope of the claims of the present invention.The claimed scope of patent of the present invention is defined by appending claims and equivalent thereof.

Claims (3)

1. the indoor lifesaving appliance of telescopic vent formula building fire, comprising: joint for respiratory device; It is characterized in that: form telescopic breather pipe external member more than two-stage by heavy caliber pipe box small-bore pipe, a local overlay segment is arranged between the pipe be nested.
2. according to the indoor lifesaving appliance of claim 1 telescopic vent formula building fire, described local overlay segment is that this part overlay segment pipe is being expanded wherein large-aperture pipe contraction, small-bore pipe to make to form each other identical cooperation tapering or draft angle on original mouth of pipe bore basis separately.
3. according to the indoor lifesaving appliance of claim 1 telescopic vent formula building fire, nose end maximum in described breather pipe external member connects joint for respiratory device, the logical outside atmosphere of minimum nose end.
