Abstract
The utility model relates to a blasting patch device capable of adjusting a blasting pressure of a buffering airbag. The blasting patch device comprises a film (1) adhered to a blasting hole in the inner surface of the airbag (5), wherein the film (1) is sewn with the airbag (5) through a sewing line (4); a sealing rubber strip (3) for blocking needle holes formed by the sewing line (4) is arranged on the outer surface of the airbag (5). By applying a principle of stress concentration, using a sewing method and the needle holes in the film and selecting the thickness of the film, the blasting patch device capable of adjusting the blasting pressure of the buffering airbag solves the fixation problem of the blasting patch and the airbag and the adjustment problem of the blasting pressure efficiently, is ingenious in design, simple in structure and reliable in performance, and effectively satisfies with different demands of various buffering airbags on the blasting pressure.
Description
Technical field
The utility model relates to explosion paster, more particularly, relates to a kind of explosion paster that can regulate buffer air bag bursting pressure.
Background technology
The buffer air bag using at present is generally made by polyurethane adhesive plaster, adopts high-pressure gas bottle or gas generator to make airbag deployment as having air source.Air bag is vapor tight, and during work, impact energy, by gas compression in air bag, realizes buffering by explosive valve explosion final vacuum.Existing explosive valve has selects polyurethane safety-valve, and the polyurethane adhesive plaster that some employing intensity is weak, is heat sealing on air bag.Air bag bursting pressure is determined by the Maximum safe pressure of safety-valve or the strength of material of explosion paster itself.The problem that this two classes explosive valve exists is: 1, specification is less, cannot meet the demand of different bladder to bursting pressure, affects buffering effect; 2, strict to the material requirements of explosive valve, must be the material that can carry out heat seal or viscose glue processing; 3, cost is higher, and buying or lead time are long, and development difficulty is larger.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of explosion paster that can regulate buffer air bag bursting pressure is provided.
The utility model solves the technical scheme that its technical matters adopts: construct a kind of explosion paster apparatus that can regulate buffer air bag bursting pressure, comprise the film being bonded on air bag inside face blast hole, described film is sewed up by suture and described air bag, the outside face of air bag is provided with sealing joint strip, and described sealing joint strip is blocked the pin hole that described suture forms.
In such scheme, described film is bonded in the inside face of described air bag by double faced adhesive tape.
In such scheme, described sealing joint strip is fixed on the outside face of described air bag by heat seal or bonding mode.
In such scheme, described film is PVC film.
Implement the explosion paster that can regulate buffer air bag bursting pressure of the present utility model, there is following beneficial effect:
1, film is after making, and its surface can produce a lot of apertures, and intensity has certain loss.Air bag is when work, and impact energy, by gas compression in air bag, produces very large interior pressure, and while surpassing the collapse strength of film, film will start to break from strength weak, and the external exhaust of air bag realizes buffering.Therefore the bursting pressure of air bag is the intensity decision of explosion paster upper film.Can adjust thin film strength with the pin code density of adjusting suture by changing the film of different-thickness, make explosion paster produce different bursting pressures.
2, the utility model has been applied the concentrated principle of stress, with the method for making and the pin hole producing on film and the selection to film thickness, the fixation problem of explosion paster and air bag, the adjusting problem of bursting pressure have effectively been solved, design ingenious, simple in structure, dependable performance, effectively met the different demands of various buffer air bags to bursting pressure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation that the utility model can regulate the explosion paster of buffer air bag bursting pressure;
Fig. 2 is the cutaway view that the utility model can regulate the explosion paster of buffer air bag bursting pressure.
The specific embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Figure 1, the explosion paster of buffer air bag bursting pressure that can regulate of the present utility model comprises the film 1 being bonded on air bag 5 inside face blast holes.
In the present embodiment, film 1 is PVC(polyvinylchloride) film, film 1 can also be PE(polyethylene), PP(polypropylene) etc. material, can need to select different materials according to intensity.Film 1 is bonded in the inside face of air bag 5 by double faced adhesive tape 2, can prevent that film 1 and the junction of inside face from leaking gas.Film 1 is also sewed up by suture 4 and air bag 5, and the outside face of air bag 5 is provided with sealing joint strip 3, and sealing joint strip 3 is blocked the pin hole that suture 4 forms, and guarantees the leak tightness of air bag 5.Film 1 is after making, and its surface can produce a lot of apertures, and intensity has certain loss.Sealing joint strip 3 can be fixed on by heat seal or bonding mode the outside face of air bag 5.
When air bag 5 work, impact energy, by the interior gas compression of air bag 5, produces very large interior pressure, and while surpassing the collapse strength of film 1, film 1 will start to break from pin hole, and the external exhaust of air bag 5 realizes buffering.Change material or the thickness of film 1, or the density of adjustable suture 4, just can adjust the intensity of film 1, make explosion paster produce different bursting pressures.
The utility model has been applied the concentrated principle of stress, pin hole and the selection to film 1 thickness with the method for making and generation on film 1, the fixation problem of explosion paster and air bag 5, the adjusting problem of bursting pressure have effectively been solved, design ingenious, simple in structure, dependable performance, effectively met the different demands of 5 pairs of bursting pressures of various buffer air bags.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
