Abstract

The utility model discloses a band structure improving inflatable bed, comprising upper and lower layers. The margin of round--coated face and a number of bands uniformly distribute between the upper and lower layers are hotly welded into a sealing inflatable entity. The band is a long cylinder shaped band. The weld lines are two symmetrical paralleled curve lines and the endpoint sleek rounding connected into a closed curve whose shape is similar to an olive without terminal. The utility model inflatable bed pad, and the shape is similar to an olive shape closed curve and no central node. No destination is arranged on the end, when the inflatable bed pad is inflated, the weld line does not break down, tear, and miss gas .The utility model has a good safety performance and durable good performance.

Description

A kind of airbed of drawstring architecture advances

Technical field

The utility model relates to a kind of airbed.

Background technology

Along with the raising of social development and people's living standard, airbed low-cost, easy to use, easy to carry is applied to every field such as amusement and recreation, health care, life staying idle at home more and more widely.Existing airbed (as shown in Figure 5) generally coats face 3, gas valve 4 by last aspect 1, subsurface 2, periphery and several drawstrings 5 of evenly arranging are formed; Periphery coats face 3, goes up aspect 1, subsurface 2, forms the inflatable entity of sealing; Several drawstrings 5 of evenly arranging, end face is fused to aspect 1, and the bottom surface is fused to subsurface 2; Drawstring 5 is rectangular cylindrical shape, and its end face is respectively the rhombus that is connected successively with last aspect, bottom surface with the weld bond 6 of subsurface, forms a plurality of nodes 7, and the end of its weld bond 6 is not connected, and has both had terminal point.Airbed when inflation, situation such as its node place, end points place be as easy as rolling off a log breaks, tear, gas leakage.

Summary of the invention

The utility model is intended at above-mentioned the deficiencies in the prior art part, provides that a kind of drawstring and inflatable entity junction are difficult for breaking, gas leakage, processing technology are simple, be not easy to damage, the airbed of durable drawstring architecture advances.

The method that its technical problem that solves the utility model adopts is: a kind of airbed of drawstring architecture advances, comprise aspect up and down, one periphery coating face and be connected into the inflatable entity of a sealing with hot melt between several evenly distributed drawstrings between aspect up and down, described drawstring is rectangular tubular drawstring, and its weld bond forms the closed curve that a profile that does not have terminal point is similar to the olive string for parallel two curves of symmetry and with the slick and sly articulating of its end points.

Drawstring welding curve described in the utility model is to be connected to form a closed curve by some elliptic arcs and the mutual slyness of some circular arcs.

The welding curve of adjacent two drawstrings described in the utility model is staggered, and is the alternate wave-like of orderly size straggly in aspect up and down.

Drawstring described in the utility model is one deck PVC film or one deck PVC film and chemical fibre, nylon or cotton knitmesh cloth are composited at least; Described upper and lower aspect is for one deck PVC film and chemical fibre, nylon or cotton knitmesh cloth are composited at least.

The welding of drawstring described in the utility model and upper and lower aspect is respectively the PVC film of drawstring and the PVC film welding of upper and lower aspect.

Inventive point of the present utility model is:, described drawstring is rectangular tubular drawstring, its weld bond forms the closed curve that a profile that does not have terminal point is similar to the olive string for parallel two curves of symmetry and with the slick and sly articulating of its end points; The weld bond profile is similar to the closed curve of olive string, the middle part do not have node, the end endless, so situation such as during the airbed inflation, do not break, tear in the weld bond place, gas leakage, security performance is good, durability is good.

Described drawstring welding curve is to be connected to form a closed curve by some elliptic arcs and the mutual slyness of some circular arcs, both two curves were symmetrically distributed, when the end points articulating is formed a closed curve, but rounding off articulating, being difficult for producing stress concentrates, can not break, tear, leak gas in the weld bond place, the life-span is long; The welding curve of described adjacent two drawstrings is staggered, and to the airbed of integral body, stressed decomposition is reasonable; Be the alternate wave-like of orderly size straggly in aspect up and down, stressed rationally.

Bed surface forms for one deck PVC film and chemical fibre, nylon or the welding of cotton knitmesh cloth at least, drawstring be one deck PVC film or at least one deck PVC film and chemical fibre, nylon or the welding of cotton knitmesh cloth form, the airbed life-span is long, not yielding; Weld is drawstring PVC film and the welding of bed surface PVC film, and technology is simple.

The specific embodiment

Below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 the utility model is further specified.

A kind of airbed of drawstring architecture advances comprises: go up aspect 1, subsurface 2, periphery and coat face 3, gas valve 4, eight evenly distributed drawstrings 5.Lower limb is fused to aspect 1, subsurface 2 edges respectively on the periphery coating face 3, forms the inflatable entity of a sealing; Gas valve 4 is arranged on periphery and coats face 3; The end face of drawstring 5, bottom surface are fused to aspect 1, subsurface 2 respectively.

Drawstring 5 is rectangular tubular.Eight drawstrings 5 evenly, be disposed on inflatable entity inner chamber; Leave the gap between the two-port of tubular drawstring 5 and the mattress circumferential surface 3.The design of the number of above-mentioned drawstring is change to some extent according to the difference of the model of mattress.

The material of drawstring 5 is that two-layer PVC film and chemical fibre, nylon or the welding of cotton knitmesh cloth form.

It all is that one deck PVC film and chemical fibre, nylon or the welding of cotton knitmesh cloth form that last aspect 1, subsurface 2, periphery coat face 3.

The welding of the end face of drawstring 5, bottom surface and last aspect 1, subsurface 2 is respectively the PVC film of aspect 1, subsurface 2 in the PVC film welding of drawstring 5.

The weld bond of the end face of drawstring 5 and last aspect 1, bottom surface and subsurface 2 is respectively a closed curve 6 of being made up of the slick and sly articulating of the end points of the parallel curve 61 (62) of two symmetries, both the two-end-point of curve 61 respectively with the two-end-point slyness articulating of another curve 62.Weld bond 6 is a closed curve 6, so the middle part does not have node, end endless.

Article two, the

parallel curve

61,62 of symmetry all is the waveform curve, as being connected to form a curve by some elliptic arc slynesses, is connected to form a curve, sine curve etc. by some elliptic arcs and the mutual slyness of some circular arcs.Slick and sly articulating is in the two-end-point of curve 62 respectively for the two-end-point of curve 61, and the differential seat angle of the end points tangential direction of curve 61 and the end points tangential direction of curve 62 is 180 degree; Or utilize an elliptic arc, circular arc slyness to connect.The parallel mutually symmetry of curve 61,62.It forms the alternate wave-like of orderly size straggly respectively in aspect up and down.

The closed curve of adjacent two drawstrings 5 is staggered.

Method of attachment in the present embodiment is that welding is that example is done explanation, but does not exceed with welding, and other for example pressing, the method that is fitted and connected also are applicable to the utility model.

The above, it only is the preferred embodiment of the utility model, when not limiting the scope that the utility model is implemented with this, promptly the simple equivalent of doing according to the utility model claim and description changes and modification, all should still belong in the scope that the utility model patent contains.
