Description
Technical field
The utility model relates to the inflatable structures of air bag, and in particular to a kind of air bag inflation fixed structure.
Background technique
Gas cylinder is generallyd use in the prior art to be inflated air bag, gas cylinder is connect with air bag by valve or tracheae,
Air bag and valve or tracheae thermoplastic seal, and one side valve mechanism is more complicated, and occupied space is big, can not accomplish to be miniaturized,
The device of requirement restricted for installation space is simultaneously not suitable for, and another aspect valve opening needs the time, quickly right for needing
The time is too long for the gas cylinder of air bag inflation, is connected by tracheae, gas initially enters tracheae in incoming air bag, transmission time
It is long, it is also not suitable for for the air bag for needing fast aeration.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of air bags that fast aeration can be directly carried out to air bag
Inflate fixed structure.
In order to solve the above-mentioned technical problem, the utility model provides a kind of air bag inflation fixed structure, including air bag sheet
Body, the airbag body air inlet with outward extension, gas cylinder are inserted into the air inlet, and gas cylinder directly fills air bag
Gas, the half that the length of the air inlet is greater than the gas cylinder length are less than the overall length of the gas cylinder, and bottleneck connects the gas cylinder
Body and bottleneck, the diameter of the bottleneck are less than the diameter of the body and bottleneck, are arranged with described in locking outside the air inlet
First snap ring of air inlet and body, the bottleneck are equipped with the second snap ring for locking the air inlet and bottleneck, pass through setting
Multiple snap rings fasten the connection of gas cylinder and air inlet more, and the diameter of bottleneck is minimum, when snap ring clamping bottleneck gas cylinder will not phase
It is mobile to air inlet, guarantee the stabilization that gas cylinder is connect with air inlet.
Further, the body is arranged with Anti-slip cover, guarantees that air inlet is connect firm with body.
Further, the Anti-slip cover is porous material, and slow gas leakage reduces gas when pressure is larger in airbag body
The air pressure of capsule ontology guarantees the lasting buffer capacity of airbag body.
Further, first snap ring and the second snap ring are flexible clip, and the diameter of first snap ring is less than bottle
The diameter of body, the diameter of second snap ring are less than the diameter of the bottleneck, under guaranteeing the leakproofness worked normally and suppressing
Gas permeability.
Further, first snap ring and the second snap ring are rubber ring, facilitate installation.
Further, first snap ring and the second snap ring include clip ontology, bolt, nut and rubber strip, the card
Hoop ontology circular arc inner surface offers two grooves being parallel to each other, and is partially connected in groove on the rubber strip, rubber strip
For lower part fractionation in outside groove, on the one hand guaranteeing that snap ring has certain activity space, another aspect snap ring will not be because of excessively being supportted
It opens and decontrols body and bottleneck.
A kind of air bag of the utility model inflates fixed structure, and beneficial effect compared with prior art is, can be direct
Fast aeration is carried out to air bag, guarantees that air bag continues buffer capacity.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the utility model Snap ring structure schematic diagram
Fig. 3 is the utility model Snap ring structure cross-sectional view.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
One structural schematic diagram of fixed structure embodiment, including airbag body are inflated as shown in Figure 1 for a kind of air bag of the present invention
1, the airbag body 1 air inlet 2 with outward extension, gas cylinder 3 is inserted into the air inlet 2, and gas cylinder 3 is directly to air bag
Ontology 1 is inflated, and without switching, aeration speed is fast, and the half that the length of the air inlet 2 is greater than 3 length of gas cylinder is small
In the overall length of the gas cylinder 3, gas cylinder 3 is facilitated to be fixedly connected with air inlet 2, bottleneck 32 connects 3 body 31 of gas cylinder and bottleneck,
The diameter of the bottleneck 32 is less than the diameter of the body 31 and bottleneck, and the locking air inlet 2 is arranged with outside the air inlet 2
With the first snap ring 4 of body 31, the second snap ring 5 for locking the air inlet 2 and bottleneck 32 is equipped at the bottleneck 32, by setting
Setting multiple snap rings fastens gas cylinder 3 and the connection of air inlet 2 more, and the diameter of bottleneck 32 is minimum, when 32 gas of snap ring clamping bottleneck
Bottle 3 will not be mobile relative to air inlet 2, guarantees the stabilization that gas cylinder 3 is connect with air inlet 2.
In the present embodiment, the body 31 is arranged with Anti-slip cover 33, the body 31 described in 4 clamping of the first snap ring, body 31
Frictional force between air inlet 2 is bigger, guarantees that air inlet 2 is connect firm with body 31, further, in the present embodiment,
The Anti-slip cover 33 be porous material, porous material can slow gas leakage, the sky in extruding gasbag ontology 1, in airbag body 1
Between compress and become smaller, air pressure increases, and when air pressure is excessively high, airbag body 1 will be hardened and lose the ability of buffering, by porous material,
Slow gas leakage reduces the air pressure of airbag body 1 when pressure is larger in airbag body 1, guarantees the lasting buffering of airbag body 1
Ability, in the present embodiment, first snap ring 4 and the second snap ring 5 are flexible clip, and pressure is excessive in airbag body 1
When, flexible clip can be slightly strutted, deflation speed is accelerated, guarantees the buffer capacity of airbag body 1, and first snap ring 4
Diameter be less than the diameter of body 31, the diameter of second snap ring 5 is less than the diameter of the bottleneck 32, it is ensured that works normally
When, snap ring can lock gas cylinder 3 and bottleneck 32 completely, and in the present embodiment, first snap ring 4 and the second snap ring 5 are rubber
Ring, it is easy for installation.
It as shown in Figures 2 and 3, is Snap ring structure in the embodiment of the present invention two, first snap ring 4 and the second snap ring 5 packet
Clip ontology 41, bolt 42, nut 43 and rubber strip 44 are included, the 41 circular arc inner surface of clip ontology offers two mutually
Parallel groove 45 is partially connected in groove 45 on the rubber strip 44, and 44 lower part fractionation of rubber strip is in outside groove 45, rubber
Adhesive tape 44 and 41 circular arc inner surface of clip ontology form an activity space, come air inlet when compensating that pressure is excessive in airbag body 1
On the one hand mouthfuls 2 displacements being propped up guarantee that snap ring has certain activity space, another aspect snap ring will not be because of excessively being strutted
And decontrol body 31 and bottleneck 32.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
