Abstract

The utility model relates to a safe device for rescue, particularly an air-column type safety air-cushion bag, which is provided with a bag surface cloth and an air inlet at one side of the bag. The utility model is characterized in that a plurality of air columns are arranged in the bag and communicated by an air pipe which is also communicated with the air inlet, and furthermore, the air pipe is connected with the air inlet hermetically. The air inlet provided with a check valve is connected with a flexible pipe hermetically, and the flexible pipe is connected with an air source device hermetically. The air source device adopts a liquid carbon dioxide can, and the air columns are vertically distributed. Generally, a safe air-cushion bag is supported by four air columns. The utility model has the advantages of light integration, high-speed inflation, and convenient operation. The utility model is widely used as a safe device for the physical protection of working high above the ground in the field, such as high layer fire protection and rescue, field installation, architecture, screen and video, etc.

Description

Gas column type safety air cushion bag

The utility model relates to the lifesaving safety device, the gas column type safety air cushion bag of recovering especially for high level.

The safety device of recovering of high level in the past, just like the patent No. 90216903.3 " safety air cushion bag ", ratio past safety device such as foamed plastics, bat or the like, that is big much progress, but shortcoming is arranged: the one, inflationtime is also not short, the 2nd, the supporting greatly again inflator of volume, to keep air pressure all the time, so under very urgent situation of the occasion time of recovering, should start to inflate gasoline engine and connect gas ducting again, also will spread the air cushion bag out, just seem in a rush, cause delay easily, be difficult to play the effect of recovering fast.

The purpose of this utility model is the shortcoming that overcomes above-mentioned safety air cushion bag, further improves, and provides aeration speed fast, need not inflate gasoline engine, easy to operate gas column type safety air cushion bag.

The utility model is finished as follows: the bag face cloth that original safety air cushion bag has the two-sided plastic-coated leather of PVC polyvinyl paulin to make, a side of bag is equipped with air inlet.On this basis, several gas columns are set in bag, have tracheae to be communicated with between the gas column, tracheae is communicated with air inlet again, and the both is tightly connected, and check-valves is installed on the air inlet, and has flexible pipe and compressed air source unit to be tightly connected.

Said gas column has 4, and vertical distribution also is to be made by the two-sided plastic-coated leather of PVC polyvinyl paulin, and is tightly connected with bag face cloth.Its structure of said check-valves is that circular step place is equipped with non-return cylinder cushion in the sleeve pipe, this pad is connected with the big first end close-fitting of steady arm, the shape of steady arm is a T shape, be with spring on it, spring base is installed the steady arm other end and close-fitting connects, and spring base is a herringbone, and tripod is movable the cooperation in the groove of internal surface of sleeve pipe, this end end that the sleeve pipe built-in hold is held bar also is provided with internal thread, is used for being tightly connected with flexible pipe.

The utility model has following advantage: owing to adopt gas column to support, the charge air conditioning volume dwindles greatly, and aeration speed is fast.

Further describe below in conjunction with accompanying drawing.

Fig. 1 is the overall structure figure of gas column type safety air cushion bag.

Fig. 2 is the structure chart of check-valves.

With reference to Fig. 1, overall structure has the bag face cloth of being made by the two-sided plastic-coated leather of PVC polyvinyl paulin (1), and parcel does not require sealing on every side.One side of bag is equipped with air inlet (4).Four gas columns (2) are arranged in bag, and vertical distribution also is to be made by the two-sided plastic-coated leather of PVC polyvinyl paulin, and is tightly connected with bag face cloth (1).Have tracheae (3) to be communicated with between the gas column (2), tracheae (3) can be made by rubber, and tracheae (3) is communicated with air inlet (4) again, more than all be tightly connected.Check-valves is installed on the air inlet (4) and flexible pipe (5) is tightly connected, flexible pipe (5) is tightly connected with compressed air source unit (6).Compressed air source unit (6) can adopt the liquid CO 2 jar.One opens the liquid CO 2 jar, and the carbon dioxide in jar just can enter check-valves along flexible pipe (5) immediately, enters air inlet (4) then, passes through tracheae (3) again and is full of 4 gas columns (2) respectively, makes integrated support, becomes the safety air cushion bag.Said check-valves, its structure are that circular step place is equipped with non-return cylinder cushion (8) in the sleeve pipe (7), and this pad (8) is connected with the big first end close-fitting of steady arm (9), and steady arm (9) is a T shape, is with spring (10) on it.Spring base (11) is installed the other end of steady arm (9) and close-fitting connects, spring base (11) is a herringbone, tripod is movable the cooperation in the groove of sleeve pipe (7) inwall, this end end that sleeve pipe (7) built-in hold is held bar (9) is provided with internal thread (12), be convenient to be connected with flexible pipe (5), also can directly be enclosed within the outside of sleeve pipe (7) with flexible pipe (5), but need add tighten ring, enhanced leaktightness connects.Non-return cylinder cushion (8) adopt rubber make and with the big end hot pressing close-fitting of steady arm (9), circular step plane is close in pad (8) and the sleeve pipe (7), plays making that gas is only accurate to be advanced in tracheae (3), and the effect that can not go out.Steady arm (9) is that metal is made, and sleeve pipe (7) adopts plastics to make with spring base (11), and tracheae (3) adopts rubber to make, and gas column (2) also can adopt rubber to make, and can adopt hot pressing with being tightly connected of bag face cloth (1), also can adopt the seccotine gummed.

For the ease of carrying, can make gas column type safety air cushion bag collapsiblely, to mix slide fastener and handgrip and make a portable case type, the part of kiss the earth also can be prepared free degree roller, is convenient to transportation, in a word, makes the safety air cushion bag, and inflation is fast, and is easy to operate.Can a plurality of safety air cushion bag permutation and combination use simultaneously, and compressed air source unit (6) also can adopt the inflation gasoline engine to supply with several gas column type safety air cushion bags inflations simultaneously to use, this will see the actual needs of the scene of recovering and decide.Can be used in extensively that high building fire-proof is recovered and the personnel protection safety devices of field work high above the ground such as open-air installation, building, video display, physical culture on.
