Abstract
The utility model relates to a multilayer pressfitting air pocket, it includes upper air pocket appearance precoat, middle gasbag precoat, lower floor's air pocket appearance precoat from top to bottom in proper order, middle gasbag precoat includes gasbag upper strata, gasbag lower floor, middle gasbag precoat is equipped with the through -hole, the gasbag upper strata is connected with upper air pocket appearance precoat through the pressfitting line, gasbag lower floor passes through the pressfitting line and is connected with lower floor air pocket appearance precoat, the pressfitting line uses the edge of through -hole to be interior all curve, and the periphery curve of pressfitting line encloses into closed curve by two U -shaped lines that the opening is relative and a pair of parallel lines of connecting two U -shaped lines. The utility model discloses having improved the shape of the pressfitting line around the through -hole, having improved the compression strength of air pocket greatly, improved great explosion pressure, it is even that the back atress is aerifyd to the air pocket, can not produce the phenomenon of bursting.
Description
Technical field
This utility model relates to multilamellar airbag technical field, is specifically related to a kind of Multi-layer force fit airbag。
Background technology
Multilamellar airbag be applied in all kinds of aerated product, such as the massage air bag on market, air matting etc.。These multilamellar airbags are usually and utilize fusion joining process to make multiple structure composite material。In manufacturing process, making the airbag components in intermediate layer before this, hole is opened in intermediate layer at middle part, engages the periphery of hole when by pressing line and levels welding。Due to the generally circular hole of through hole that intermediate layer is offered, pressing line during existing joint is also circular pressing line, and so, airbag is airbag inflation after inflation, and pressing line becomes arc shape, and the stress of bore periphery becomes unbalanced, it is easy to airbag is burst。
Utility model content
The purpose of this utility model is in that to overcome the defect of above-mentioned prior art, it is provided that a kind of Multi-layer force fit airbag, and its compressive resistance is high, stress equalization internal after inflation, will not produce Decrepitation Phenomena。
For achieving the above object, this utility model adopts the following technical scheme that
A kind of Multi-layer force fit airbag, it from top to bottom includes the upper strata airbag outer mold surface bed of material, center sleeve precoat, lower floor's airbag outer mold surface bed of material successively；Described center sleeve precoat includes air bag upper strata, air bag lower floor, described center sleeve precoat is provided with through hole, described air bag upper strata is connected with the upper strata airbag outer mold surface bed of material by pressing line, and described air bag lower floor passes through pressing line and is connected with the lower floor airbag outer mold surface bed of material；Described pressing line is with the edge of through hole for inner circumferential curve, and the periphery curve of pressing line is by the relative U-shaped line of two openings and connects the pair of parallel straight line of two U-shaped lines and surrounds closed curve。
Preferably, the described upper strata airbag outer mold surface bed of material includes nylon layer of cloth, is placed in the TPU layer below nylon layer of cloth；The described lower floor airbag outer mold surface bed of material includes TPU layer, is placed in the nylon layer of cloth below TPU layer。
Preferably, described air bag upper strata includes TPU layer, is placed in the nylon layer of cloth below TPU layer；Described air bag lower floor includes nylon layer of cloth, is placed in the TPU layer below nylon layer of cloth。
Compared with prior art, the beneficial effects of the utility model are:
This utility model improves the shape of the pressing line around through hole, substantially increases the compressive resistance of airbag, improves maximum burst pressure, and uniform force after air bag inflator will not produce Decrepitation Phenomena。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation on air bag upper strata of the present utility model。
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further。
Refer to Fig. 1, Fig. 2, this utility model one Multi-layer force fit airbag, it from top to bottom includes the upper strata airbag outer mold surface bed of material 1, center sleeve precoat 2, lower floor's airbag outer mold surface bed of material 3 successively。Described center sleeve precoat 2 includes air bag upper strata 21, air bag lower floor 2。Described center sleeve precoat 2 is provided with through hole 23。Described air bag upper strata 21 is connected with the upper strata airbag outer mold surface bed of material by pressing line 24。Described air bag lower floor 22 is connected with the lower floor airbag outer mold surface bed of material 3 by pressing line 24。Described pressing line 24 is with the edge of through hole 23 for inner circumferential curve, and the periphery curve of pressing line 24 is by the relative U-shaped line of two openings and connects the pair of parallel straight line of two U-shaped lines and surrounds closed curve。
As further improvement of the utility model scheme, the described upper strata airbag outer mold surface bed of material 1 includes nylon layer of cloth 11, is placed in the TPU layer 12 below nylon layer of cloth 11。The described lower floor airbag outer mold surface bed of material 3 includes TPU layer 31, is placed in the nylon layer of cloth 32 below TPU layer 31。
As further improvement of the utility model scheme, described air bag upper strata 21 includes TPU layer 21a, is placed in the nylon layer of cloth 21b below TPU layer 21a。Described air bag lower floor 22 includes nylon layer of cloth 22a, is placed in the TPU layer 22b below nylon layer of cloth 22a。
For a person skilled in the art, can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims。
