Abstract

The utility model relates to an improved joint structure of an inflating pipe for an air cushion bed, which is characterized in that a long connecting strip is made of materials which can be melted by heat, the cross section of the long connecting strip is I-shaped, and both sides of the long connecting strip are provided with clamping slots. The outer lateral margins of the upper walls of the clamping slots of both sides are slightly downwards bent and sagged, and both sides of the long edges of the clamping slots are inwards folded to form a butt joint shape by a sliver gelatine cloth. The long connecting strip is arranged in the abutment joint of the sliver gelatine cloth, and two butt joint edges are stuffed in the clamping slots of both sides of the long connecting strip. The two butt joint cloth edges which are stuffed can be preliminarily clamped and fixed by the flagging outer margins of the upper walls of the clamping slots, and the two butt joint cloth edges are not easy to deviate from the back part and are combined in a high-frequency hot melt mode to form an inflating pipe of an air cushion bed. Therefore, the seams are easily aligned and are not easily to deviate. Thereby, the rate of qualified products is improved.

Description

Improved the air bed gas tube of seam construction

The utility model relates to a kind of air bed, particularly a kind of air bed gas tube that has improved seam construction.

As shown in Figure 1, it is schematic perspective view for a known air bed, and Fig. 2 is the seam construction schematic perspective view of a known air bed gas tube, in Fig. 1, rearrange each body 10 of air bed ', all be its both sides, long limit inwardly to be converted into the butt joint shape with a rectangular colloid cloth 10, cooperation engages cloth 20 with one and places inboard between rectangular colloid cloth 10 abutment joints, and make abutment joint aim at the centre that is positioned at joint cloth 20, and with HF hot melt be combined into a long tube body 10 ', the last gas tube that again long tube body 10 ' two ends is also formed an air bed with the HF hot melt sealing.

Yet aforesaid gas tube seam form of construction work, because it engages cloth 20 is the inboards that place rectangular colloid cloth 10, the cause that is covered by rectangular colloid cloth 10, so before HF hot melt, be not easy to engage the seam crossing that cloth 20 is aligned in rectangular colloid cloth 10 accurately, and may form joint cloth 20 shown in the dotted line of Fig. 3, it engages cloth 20 and deviates from the seam of rectangular colloid cloth 10 because of not aiming at jointing line, make the shape feelings that not driving fit of seam is arranged behind the HF hot melt, easily cause the waste product of lump in the abdomen defect.

So how to design a kind of seam integrated structure of gas tube, be to be easy to accurately aim at seaming position in the seam integrated structure of colloid cloth, and can fixedly be difficult for departing from and accurately hot melt be the difficulty place that the utility model institute desire row solves in conjunction with to reduce the number of rejects and seconds.

Main purpose of the present utility model is that a kind of air bed gas tube that has improved seam construction will be provided, be to connect the bar structure with a length that has clip slot in both sides, provide gripping of two pairs of edge fits of rectangular colloid cloth to be difficult for departing from, so that the carrying out of HF hot melt processing makes simple simplification of operation improve output rapidly.

Of the present utility model time a purpose is that a kind of air bed gas tube that has improved seam construction will be provided, connect bar clamping between the seam of rectangular colloid cloth by length, make operating personnel just be easy to aim at seam, and be easy to of the generation of certain sealed engagement to reduce the number of rejects and seconds by appearance is visual.

For realizing above-mentioned purpose, the utility model is mainly with a rectangular colloid cloth, shape is being docked to invagination in its both sides, long limit, article one, elongated dowel bar places the seam crossing of butt joint, be combined into a long tube body with HF hot melt, these body two ends also form with the HF hot melt sealing, it is characterized in that: make but this dowel bar is a hot melt material, its section is the I-shaped length that has clip slot in both sides and connects bar, and curved slightly downwards the hanging down of the upper wall lateral border of both sides clip slot is Shape, long connecing between the abutment joint that bar places rectangular colloid cloth, long connecing in the both sides clip slot of bar gone into by this two butt joints frontier fortress, the two butt joint selvedges that the sagging lateral border of mat clip slot upper wall can tentatively fixedly be filled in, be difficult for departing from and be convenient to follow-uply engage with HF hot melt, and form an air bed gas tube, reach convenient and simple for operation, rapid and raising output, the purpose of reducing the number of rejects and seconds.

The utility model is simple in structure, its function and benefit is: this structure connects the bar structure with the length of particular design tool two clip slots, gripping to make and being difficult for departing from of two pairs of edge fits of rectangular colloid cloth is provided, and be convenient to the carrying out of follow-up HF hot melt processing, make simple simplification of operation improve output fast, and in the operation easily from external visual aligning seam, and the really generation of sealed engagement to reduce the number of rejects and seconds.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.

As shown in Figure 4, be perspective exploded view of the present utility model, it is mainly will grow the both sides, limit with a rectangular colloid cloth 10 inwardly to be converted into the butt joint shape, but cooperation is made a section with hot melt material and is the I-shaped length that has clip slot 31 in both sides and connects bar 30, and long curved slightly downwards the hanging down of upper wall lateral border that connects bar 30 both sides clip slots 31 is

Shape, in conjunction with the time connect between the abutment joint that bar 30 places rectangular colloid cloth 10 long, and 10 liang of rectangular colloid cloth butt joint frontier fortress gone into long connecing in the both sides clip slot of bar 30, as shown in Figure 5, its by the sagging lateral border of clip slot 31 upper walls tentatively 10 two pairs of edge fits of rectangular colloid cloth of filling in of clamping fix, 10 two pairs of edge fits of rectangular colloid cloth are really aimed at are difficult for departing from, and be convenient to HF hot melt be combined into as shown in Figure 6 long tube body 10 '.

As shown in Figure 7, make the stereogram of air bed gas tube finished product for the utility model, be with long tube body 10 ' both ends 12 ' also with the HF hot melt sealing and reserve a pore 11 ', permutation and combination one-tenth air bed as shown in Figure 1 just can be provided.

In sum, the utlity model has on the industry practicality as can be known, and the utility model do not see any publication, also have a novelty, when the regulation that meets Patent Law, so propose utility application in accordance with the law with advanced.
