Abstract
The utility model discloses an improved structure of aeration pad, comprising an airtight flexible air sac and a spongy cushion. The spongy cushion is warped by the flexible air sac made of instretchable material, and the inner face of the flexible air sac is bonded with the spongy cushion. Owing to that the utility model combines the flexible air sac and the spongy cushion together through hot melt coating or adhesive, relative displacement can not happen between the contact surfaces of the flexible air sac and the spongy cushion, and the aeration pad is uneasy to be crushed.
Description
Technical field
The utility model relates to a kind of field of furniture, particularly relates to a kind of improvement structure of inflatable packer.
Background technology
Known inflatable packer mainly is made up of airtight flexible air-bag and cavernous body located therein.Flexible air-bag is generally made by wear-resisting linings such as nylon.During collection, flexible air-bag is rolled, the air in the flexible air-bag is discharged from valve; During use, the flexible air-bag valve is opened, because atmospheric pressure big than in the flexible air-bag, air charges into the container chamber of flexible air-bag automatically from valve.Thereby the soft material that its top layer of the flexible air-bag in this inflatable packer needs stretch-proof therefore can't make fur or flannelette one class lacks comfort.
The utility model content
The purpose of this utility model is to provide a kind of improvement structure of more comfortable inflatable packer.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of improvement structure of inflatable packer, and it is mainly by airtight flexible air-bag be located in it cavernous body and form; Offer valve on the flexible air-bag; The skin of described flexible air-bag is hair, down material, and the intermediate layer is tensile layer not, and the TPU material that is used to seal and the foam-rubber cushion heat of its internal layer are melted together.
Described not tensile layer is the PU coating that is evenly coated on hair, the down material.
Described not tensile layer is a nylon.
The TPU material of described not tensile layer and internal layer connects by TPU is gluing.
After adopting such scheme, because the utility model is with fur, the fine hair top layer as flexible air-bag, increased the comfort level of inflatable packer, thereby because the TPU material that is used to seal can't inflate inflatable packer drawing to be easy to break when stretching, thus inside add one deck not tensile layer with the problem of the easy stretching that solves fur, fine hair.Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a three-dimensional cutaway view of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of improvement structure of inflatable packer, and it is mainly by airtight flexible air-bag 1 be located in it cavernous body 2 and form; Offer valve 3 on the flexible air-bag; The skin of flexible air-bag 1 is hair, down material 11, and the intermediate layer is tensile layer 12 not, and the TPU material that is used to seal 13 and cavernous body 2 heat of its internal layer are melted together.Form a complete flexible air-bag for these three layers, outer field hair, down material 11 make air cushion comfortable, the TPU layer of internal layer plays airtight effect, but because TPU material 13 is thinner, under situation about stretching, easily pulled open, and hair, down material 11 is easy stretching material, thus be situated between add one deck not tensile layer can realize the purpose of this utility model.
First kind of embodiment of the present utility model is: the inner surface at hair, down material 11 directly sprays the non-stretchable PU coating of one deck 12`, and this PU coating is evenly coated in the inner surface of flannelette napped fabric layer 1, connects with TPU is gluing between PU coating 12` and the TPU material 13.
Another kind of embodiment of the present utility model is: tensile layer adopts the very little nylon 12`` of draftability, as uses other not alternative nylon of expanded material, should belong to and be equal to replacement, is the utility model protection domain.
Claims (4)
1, a kind of improvement structure of inflatable packer, it is mainly by airtight flexible air-bag be located in it cavernous body and form; Offer valve on the described flexible air-bag; It is characterized in that: the skin of described flexible air-bag is hair, down material, and the intermediate layer is tensile layer not, and the TPU material that is used to seal and the foam-rubber cushion heat of its internal layer are melted together.
2, the improvement structure of inflatable packer according to claim 1 is characterized in that: described not tensile layer is the PU coating that is evenly coated on hair, the down material.
