Abstract

The utility model provides an improved structure of expanding-proof space bag, mainly comprising an integrally formed cylindraceous expanding-proof inner slice and an integrally formed cylindraceous bag edge slice. When implementing, the cylindraceous expanding-proof inner slice and the cylindraceous bag edge slice are respectively designed into foursquare shape. The cylindraceous expanding-proof inner slice is arranged in the cylindraceous bag edge slice, the central line position of the four edges of the cylindraceous bag edge slice is taken as a vehicle seam for folding with the four angle lines of the expanding-proof inner slice, and the vehicle seam is connected into an expanding-proof bag. Then rings are suspended at the upper cover and the lower cover of the vehicle seam at the upper end and the lower end of the bag and the vehicle seam at the circumference of the bag for forming the expanding-proof space bag of the utility model. Since the expanding-proof inner slice and the bag edge slice are formed integrally, the expanding-proof space bag can be producted in large scale, vehicle seam can be reduced, expanding-proof strength can be enhanced, production speed can be increased, and cost can be reduced.

Description

The improvement structure of anti-expansion space bag

Technical field

The utility model relates to a kind of improvement structure of anti-expansion space bag, and the structure that refers to a kind of anti-expansion space bag especially can strengthen anti-expanding ability, and can promote the effect of throughput rate and cost-cutting after improvement.

Background technology

Known have the structure of official seal expansion space bag (to see also Fig. 1, Fig. 2, Fig. 3), its bag 10 consists predominantly of a U-shaped sheet 20, two limit sheets 30 and four interior sheets 40 of anti-expansion, it is that two limit sheet 30 sewings are connected in two opening edges 21 of U-shaped sheet 20 and form tetragonal bag 10, and four interior sheets 40 of anti-expansion are its both sides sewing to be connected in two of U-shaped sheet 20 turn up limit 22 and 30 predetermined sewings of both sides sheet place 31, lower end sewing loam cake 50 and lower cover 60 thereon again, and form anti-expansion space bag in bag side seam suspension ring 70, it is to prevent bag 10 expansions with sheet 40 in this anti-expansion, the topmost shortcoming of this kind anti-expansion space bag is that the cutting of sheet in anti-the expansion is with the manual mode operation, comparatively bother time-consuming in the operation, also have the suddenly big or suddenly small situation that is difficult to grasp on the size, not only influence throughput rate and quality, and cost is also higher, in addition, sheet 40 both sides sewings, just can cause suture to be pullled coming and lost the function that anti-bag is expanded if the bad situation of sewing is arranged in predetermined sewing place 31 in should anti-expanding.

The utility model content

The purpose of this utility model is that aforementioned known anti-expansion space bag throughput rate is low in order to solve, cost is high and the anti-interior sheet sewing place undercapacity that expands, suture takes place easily pullled the various shortcomings that come, a kind of improvement structure of anti-expansion space bag is provided, but modularity production, can reduce thread and increase anti-tensile strength, and can promote throughput rate and cost-cutting.It is configured to not seen before, is one to have novelty and progressive, and can promotes result of use, meets the condition of novel patent.

The improvement structure of a kind of anti-expansion space bag of the utility model, it is characterized in that, include anti-interior sheet and the integrated tubular bag limit sheet of expanding of an integrated tubular, it is with in the sheet installing tube-shape bag body limit sheet in the anti-expansion of tubular, and be set at quadrangle respectively, and the linea angulata at four angles of sheet is folding and close and sewing connects into anti-expansion bag in expanding so that tubular is anti-as the sewing place with four limit center lines of tubular bag limit sheet again.

The improvement structure of a kind of anti-expansion space bag of the utility model, but not only modularity production can reduce thread and increase anti-tensile strength, and can promote throughput rate and cost-cutting.

Description of drawings

For further specifying technology contents of the present utility model, below in conjunction with embodiment and accompanying drawing describes in detail as after, wherein:

Fig. 1 is known anti-expansion space bag exploded drawings.

Fig. 2 is known anti-expansion space bag External view.

Fig. 3 is known anti-expansion space bag cross-sectional view.

Fig. 4 is the utility model exploded drawings.

Fig. 5 is the utility model External view.

Fig. 6 is the utility model cross-sectional view.

The specific embodiment

Structure of the present utility model and special efficacy thereof are described as follows according to the further more detailed bundle of most preferred embodiment shown in the drawings:

As Fig. 3, Fig. 4, shown in Figure 5, the improvement structure of the anti-expansion of the utility model space bag consists predominantly of sheet 1 and integrated tubular bag limit sheet 2 in the anti-expansion of an integrated tubular, be that sheet 1 and tubular bag limit sheet 2 peripheries in the anti-expansion of this tubular are set at quadrangle respectively during enforcement, its be with this tubular is anti-expand in sheet 1 place in the tubular bag limit sheet 2 and with the midline position on these sheet 2 four limits, tubular bag limit as sewing place 11, four linea angulatas of sheet 1 are folding and close and sewing connects into anti-expansion bag 10 in expanding with tubular is anti-, again in these bag 10 upper and lower side sewing loam cake 50 and lower covers 60, and form the anti-expansion of the utility model space bag in bag 10 peripheral sewing suspension ring 70, because sheet 1 and tubular bag limit sheet 2 all are formed in one in the anti-expansion of its tubular, but not only modularity production, can reduce suture and strengthen anti-tensile strength, and can promote throughput rate and quality and cost-cutting.

In sum, the improvement structure of the anti-expansion of the utility model space bag mainly is provided with sheet and integrated bag limit sheet in the anti-expansion of an integrated tubular, it is that sheet in the anti-expansion of tubular is placed in the sheet of tubular bag limit, and both are set at quadrangle respectively, and it is folding and close and sewing connects into anti-expansion bag with the midline position on bag four limits as four linea angulatas of sheet in sewing place and anti-the expansion, but its not only modularity production, and can strengthen sewing intensity, increase anti-the planning function, and can promote throughput rate and quality, and cost-cutting, it is configured to not seen before, be one to have novelty and progressive and can promote and use effect, meet novel patent condition, so apply for a patent in accordance with the law.

Claims (1)

1, a kind of improvement of anti-expansion space bag structure, it is characterized in that, include anti-interior sheet and the integrated tubular bag limit sheet of expanding of an integrated tubular, it is with in the sheet installing tube-shape bag body limit sheet in the anti-expansion of tubular, and be set at quadrangle respectively, and the linea angulata at four angles of sheet is folding and close and sewing connects into anti-expansion bag in expanding so that tubular is anti-as the sewing place with four limit center lines of tubular bag limit sheet again.
