Abstract
An inflating mattress with a closed circle inner sheet essentially comprises a facial sheet, a bottom sheet, a circle sheet and a drawstring group, an air valve. The utility model is characterized in that the inner side of the circle sheet is arranged with a closed inner sheet; the edges of the upper and lower borders of the inner cycle sheet are separately connected with the facial sheet and the bottom sheet; the inner circle sheet is provided with the air valve. The utility model has the advantages of that the closed circle inner sheet is adopted to reduce the pressure of the joints among the sheets in the inflating mattress, thereby avoiding the pressure drop or air leakage caused by the deforming and damaging of the stressed fabric, prolonging the service life of the inflating mattress.
Description
Technical field
The utility model relates to a kind of airbed, particularly a kind of airbed that encloses sheet in the closed annular that is provided with.
Technical background
Popular along with airbed, more and more be used as the standby mattress of family or use when camping out of doors, but because the present airbed of producing generally adopts PVC adhesive plaster or PVC flocking adhesive plaster as raw material, it is that the air pressure inside value that can bear of airbed is lower that PVC adhesive plaster or PVC Flock Adhesive are furnished with a shortcoming that is difficult to overcome, inflation back PVC or PVC flocking adhesive plaster are stressed to be easy to generate stretching and to be difficult to return to original state, therefore because of adhesive plaster stretches to produce to be out of shape the air pressure inside value is descended easily after the airbed inflation, this not only has influence on the outward appearance of airbed, and has influenced the comfort level and the service life of airbed greatly.The airbed that has reduces PVC adhesive plaster stretcher strain stressed after as the moulding material of airbed with the intensity that increases airbed in order to address this problem the Reinforced PVC adhesive plaster (hereinafter to be referred as the Reinforced PVC adhesive plaster) that adopts composite nylon fabric or dacron, this method makes the situation of PVC adhesive plaster stretcher strain make moderate progress, but there is certain defective equally, PVC layer as the Reinforced PVC adhesive plaster of heat seal face is thinner usually, and the peel strength that PVC layer and RIPSTOP or dacron are fitted is lower, so the position that sheet dough sheet and the mutual heat seal of egative film are particularly enclosed in the heat seal position of airbed inflation back Reinforced PVC adhesive plaster occurs the PVC layer easily and strengthens the phenomenon that fabric stripping causes mattress gas leakage.
Summary of the invention
Goal of the invention of the present utility model is at the defective that exists in the prior art, and the utility model provides a kind of airbed that encloses sheet in the closed annular that is provided with.
The utility model mainly comprises: dough sheet, egative film, enclose sheet and drawstring group, air valve, it is characterized in that the described sheet inboard of enclosing is provided with in the closed annular and encloses sheet, in enclose sheet and be connected with egative film with dough sheet respectively at the edge, both sides up and down, in enclose sheet and be provided with Air filling and discharging valves, the arranged outside of air valve is being enclosed the aperture position of sheet.The dough sheet of PVC adhesive plaster, egative film, enclose and be provided with the enhancing fabric in the sheet.
The utility model has the advantages that employing is set up in airbed in the closed annular encloses sheet, alleviated the pressure of seam crossing between interior each sheet of airbed, prevent because of airbed lining stress deformation, damage the pressure cause and reduce or gas leak phenomenon, increased airbed service life.

The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing:
Referring to Fig. 1, the dough sheet 1 of the utility model airbed, egative film 2 and to enclose sheet 3 be that material is the PVC adhesive plaster (hereinafter to be referred as the Reinforced PVC adhesive plaster) that has enhancement layer, they pass through the method thermal synthesis type of high-frequency welding each other, adopting the Reinforced PVC adhesive plaster mainly is the problem that solves common PVC adhesive plaster or the easy stretcher strain in flocking PVC adhesive plaster inflation back, can be that airbed can bear bigger air pressure inside value simultaneously.Drawstring 4 can adopt vertical pulling band, circle hole shape drawstring or other forms of drawstring for interconnecting with dough sheet 1 and egative film 2 respectively in the concrete process of implementing.In enclose sheet 6 and be closed annular, it be arranged at the outer gusset sheet 3 of drawstring 4 inboard and with the position of enclosing sheet 3 next-door neighbours, its material is common PVC adhesive plaster, in enclose sheet 6 two ends up and down interconnect with dough sheet 1 and egative film 2 respectively, form inflatable air chamber with this in interior sheet 6 inside of enclosing, enclose on the sheet 6 in the air valve 5 that the air chamber that encloses sheet 6 inside in giving charges and discharge gas is installed in, establish circle hole shape opening 7 with air valve 5 corresponding positions enclosing on the sheet 3, can charge and discharge the operation of gas via opening 7 and air valve 5.In enclose in the air chamber inflation back of sheet 6 inside and enclose the inboard of enclosing sheet 3 that sheet 6 outwards is attached to close together, enclosing 3 of sheets internally encloses sheet 6 and plays inside supporting role, enclose like this sheet 6 outwards expansion be subjected to enclosing the limiting its stressed reducing greatly of sheet 3 and be in low stress, in enclose sheet 6 and dough sheet 1 and egative film 2 mutual heat seals the stressed of weld seam B reduce equally greatly, weld seam B more firmly is difficult for peeling off the phenomenon that causes mattress to leak gas like this.Referring to Fig. 2.
Claims (2)
1. one kind is provided with the airbed that encloses sheet in the closed annular, mainly comprise: dough sheet, egative film, enclose sheet and drawstring group, air valve, it is characterized in that the described sheet inboard of enclosing is provided with in the closed annular and encloses sheet, in enclose sheet and be connected with egative film with dough sheet respectively at the edge, both sides up and down, in enclose sheet and be provided with Air filling and discharging valves, the arranged outside of air valve is being enclosed the aperture position of sheet.
