Abstract
The utility model relates to a lifesaving parachute. The utility model comprises parachute jackets, a parachute rope and a bundling belt, wherein, the quantity of the parachute jackets is two to four, and the parachute jackets are overlapped at intervals; the edge of each parachute jacket is connected through a pull rope. The upper end of the parachute rope is connected with the parachute jacket on the lowermost end, and the lower end of the parachute rope is connected with the bundling belt. The centers of the tops of a second parachute jacket and the parachute jackets under the second parachute jacket are provided with vent holes. The utility model uses at least two layers of the parachute jackets to be overlapped at intervals, pressure born by each layer of the parachute jacket is reduced, and the fastness and the reliability of the utility model are greatly improved; the sizes of the parachute jackets are gradually reduced from top to bottom, and the integral appearance of the utility model is similar to an inversed conical shape; resistance born by the bottom during landing is reduced, and the landing directivity is made to be more stable; the vent holes on the tops of the parachute jackets on the lower part can guide airflow from the center to upper layers, and the landing stability is further improved.
Description
Technical field
The utility model relates to a kind of life-saving para chute, and the personnel on building and the altitude plant of being mainly used in escape when in danger and recover.
Background technology
Along with improving constantly of people's living standard, the high stratification of dwelling house is more and more general.Become increasingly conspicuous so go up the problem of personnel's escape when in danger of inhabitation or operation at skyscraper (or equipment), often (as fire) has little time to withdraw when running into accident, causes serious consequence.Also there is not at present a kind of equipment of withdrawing escape from the skyscraper fast that is specifically designed to.
Summary of the invention
The purpose of this utility model just provides a kind of life-saving para chute that can make people's safe and quick escape on skyscraper or the equipment.
The technical solution of the utility model is: comprise canopy, umbrella rope and bundling belt, described canopy has 2-4 space overlapping, connect by stay cord between the edge of each canopy, described umbrella rope upper end is connected the lower end connection bundling belt of this umbrella rope with bottom canopy; Top center at second and following canopy has air extractor vent.
Described canopy has 3, and its diameter successively decreases from top to bottom.
Described canopy is made of gores and stiffening band, and stiffening band is on the uniform gores that is connected sphere shape of radiant rays with the center of canopy, and stay cord between described canopy and umbrella rope all are connected the end of described stiffening band.
The utility model adopts two-layer at least canopy interval overlapping, has reduced the pressure that every layer of canopy bore, and its fastness reliability is greatly improved; The canopy size reduces from top to bottom gradually, make the taper of its monnolithic case image inversion, reduce bottom suffered resistance when landing, make the directivity of landing more stable, following canopy top air extractor vent can be directed to the upper strata from the center with air-flow, has further improved the stability of landing.
Description of drawings

Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the birds-eye view of following two canopies among Fig. 1.
The specific embodiment
Referring to Fig. 1-Fig. 3, embodiment of the present utility model is made up of 3 canopy 1 section gaps, connects by stay cord 2 between the edge of each canopy 1, connects the upper end of umbrella rope 3 at the edge of nethermost canopy 1, and its lower end is connected with bundling belt (braces) 4.Bundling belt 4 can adopt existing common life-saving para chute bundling belt.Canopy 1 is by the gores 12 of hemisphere face shape and connectedly be the uniform stiffening band of radiant rays 11 with its center and constitute.Above-mentioned stay cord 2 all is connected with the end of this stiffening band 11 with umbrella rope 3.All there is air extractor vent 13 at the center of two canopies 1 below.
The embodiment data of an experiment of the utility model are as follows: go up 15 meters of canopy deployment diameter, 14 meters of middle canopy deployment diameter, 13 meters of following canopy deployment diameter.Cut out body weight and be 70 kilograms personnel from floor rooms 35 (about 100 meters high) safety reduce to ground.Horizontal drift is less than 0.6 meter.
