Description
Technical field
The present invention relates to airbag, the sealing structure and its method of specially a kind of airbag.
Background technology
Traditional air column bag includes including at least one gas column on bag, the bag, and the gas column is through sealing two panels
The periphery hot-sealing line of diaphragm and formed between two panels diaphragm, one end of the gas column is gas column air inlet, and the gas column enters
Gas port is provided with non-return valve film and stretches into a segment distance in gas column, and the non-return valve film is made up of two panels valve film, two plate valve films
The outer surface of piece is connected with the two panels diaphragm heat-sealing of gas column respectively, and the non-return valve film is located at two of the non-return valve film at air inlet
The inner surface of piece valve film scribbles heat-resistant adhesive, makes to form gas column filling channel between two panels valve film.The traditional gas of the kind
The only gas principle of post bag：Gas is from filling channel air inlet into gas column between the two panels valve film on non-return valve film during inflation,
As the gas in gas column is more and more, two panels valve film on non-return valve film is in gas column by two panels in the presence of gas pressure
Valve film lower compression is blocked, and then gas can not be flowed out between two panels valve film.Traditional air column bag by
Set non-return valve film to realize between two panels diaphragm and stop gas, there are the following problems for it：First, traditional air column bag sealing function need to be in gas
Inner membrance, i.e. non-return valve are set in post bag outer membrane, closing inflation effect is just can reach, its is complicated, and manufacturing cost is high；2nd, only
The intensity for relying on the closing filling channel of the check valve arrangement of inner membrance is not enough, through the air in filling channel after a period of time just
Can be escaped by inner membrance, its inflate it is complete in the case of, stand, a gas leakage in month about 30%~40%, and when air sealing body by
During to temperature change, gas leak phenomenon can be equally produced so that airbag protection article performance, it is not fully up to expectations.
The content of the invention
Present invention aims at：Through small channel part and blocking part design there is provided a kind of manufacturing cost is low, and thoroughly
Cross sealing structure and its method that shirtsleeve operation just can reach the airbag of the preferable using effect of user.
The present invention can be achieved through the following technical solutions：
A kind of sealing structure of airbag, includes an airbag body, and the airbag body is provided with an at least opening portion, the gas
Provided with least one channel part at the opening portion side in bag body, a diameter of below 2.9mm of the channel part, and in
The channel part is provided with an at least accommodation space at the opening portion side, and at least one is provided with the accommodation space
Blocking part at the channel part side.In this way, the blow gun of charger can be used to insert the opening portion of airbag body for user
To be inflated to airbag body, and air enters in accommodation space via channel part so that accommodation space formation bulging, works as appearance
When bulging between being empty reaches saturation, airbag body will become tight state sample, and by blocking part closed channel portion, and in
In 1.5 seconds after channel part locking closing, close it channel part progress hot melt, just airbag body can be made to reach close to percentage
Hundred inflation effect, and operating process is comparatively simple, and compared with the airbag of tradition, it is not necessary to the non-return valve knot of inner membrance
Structure, is effectively simplified air bag structure, while effectively reduction cost of material and manufacturing cost.
The sealing structure and its method of airbag of the present invention, with following beneficial effect：
Firstth, simple in construction, airbag of the present invention is compared with the airbag of tradition, it is not necessary to the check valve arrangement of inner membrance, effectively simple
Air bag structure；
Secondth, easy to make, because airbag of the present invention does not need the check valve arrangement of inner membrance, its one side need not make check
Valve, on the other hand eliminates the process being fabricated into non-return valve in airbag, is effectively simplified production process；
3rd, cost is low, because airbag of the present invention does not need the check valve arrangement of inner membrance, effectively reduces parts, reduces
Cost of material and cost of manufacture；
4th, air inlet is quick, and user is inflated using charger to airbag, and gas enters in airbag via channel part,
Its air inlet is quick, and effect is good；
5th, lock gas effect is good, and air enters in accommodation space via channel part during inflation causes accommodation space formation bulging, when
When the bulging of accommodation space reaches saturation, airbag body will become tight state sample, and carry out short time envelope by blocking part
Closing quickly closes it channel part progress hot melt, and airbag body can just reached close to inflation effect very, channel part
Hot melt closing is carried out, it is good that it locks gas effect.

Embodiment
In order that those skilled in the art will better understand the technical solution of the present invention, with reference to example and accompanying drawing pair
Product of the present invention is described in further detail.
Embodiment 1
As shown in figure 1, a kind of sealing structure of airbag, include an airbag body 1, the airbag body 1 includes at least 1 the
On one base material 11 and at least one the second base material 12 in the first base material 11, the base material 12 of the first base material 11 and second
Provided with an at least connecting portion 13, the airbag body 1 is provided with an at least opening portion 14, the airbag body 1 provided with least
One is located at the channel part 16 at the side of opening portion 14, a diameter of below 2.9mm of the channel part 16, i.e., described channel part 16
Diameter be less than 2.9mm, and an at least accommodation space 17 is provided with the side of opening portion 14 in the channel part 16, then at
Provided with least one blocking part 18 at the side of channel part 16 in the accommodation space 17, the blocking part 18 is located at accommodating
The side in space 17 is provided with least one guide groove 19, has an at least air inlet between the opening portion 14 and the channel part 16
Tube passage 15.
As shown in Figures 1 to 5, when user is inflated and sealed to airbag body 1 of the present invention, it can enter according to the following steps
OK：
The first step, is inflated to the opening portion 14 of airbag body 1；
Second step, air enters in accommodation space 17 via channel part 16 forms bulging；
3rd step, when the bulging of accommodation space 17 reaches saturation, makes to lead to by blocking part 18 with the formation locking of accommodation space 17
Road portion 16 is closed；
4th step, in 1.5 seconds after the locking of channel part 16 closing, channel part 16 is carried out into hot melt closes it.
As shown in Figures 1 to 5, airbag body 1 of the present invention is connected by the base material 12 of the first base material 11 and second and formed, described
The base material 12 of the first base material 11 and second is hot melt material, the hot melt material be nylon or poly- polyethylene terephthalate PET or
Person's high density polyethylene (HDPE) PE or plastics, make to have on the base material 12 of the first base material 11 and second connecting portion being connected through hot melt
13, and the formation of airbag body 1 is housed the accommodation space 17 of air, and there is channel part 16 on accommodation space 17, it is described logical
Road portion 16 is a diameter of below 2.9mm micro- air flue, and is formed with accommodation space 17 and is available for keeping out keeping out for channel part 16
Portion 18, the blocking part 18 is same to be formed by hot melt, and has air inlet tube passage 15 between channel part 16 and opening portion 14 so that
