Abstract
The utility model discloses a novel arc-shaped zipper. The novel arc-shaped zipper comprises an outer arc cotton belt, outer arc chain teeth arranged on the outer arc cotton belt, inner arc cotton belt, and inner arc chain teeth arranged on the inner arc cotton belt, wherein the space width of the outer arc chain teeth is larger than that of the inner arc chain teeth. According to the novel arc-shaped zipper, the outer arc chain teeth and the inner arc chain teeth are mutually meshed after the zipper is zipped up, and the outer arc cotton belt and the inner arc cotton belt bend towards the inner arc cotton belt; due to the fact that braids with good extensibility are adopted in the zipper, the outer arc cotton belt can extend naturally, the inner arc cotton belt can contract naturally, and obvious wave-shaped drapes do not exist; when the arc-shaped zipper is sewn on arc-shaped openings of objects like tents or cases, the outer arc cotton belt and the inner arc cotton belt can be directly sewn on an inner ring and an outer ring of the arc-shaped openings respectively in a corresponding mode without the need of shearing a cut, therefore sewing of the arc-shaped zipper is simple and efficient, and the outer arc cotton belt and the inner arc cotton belt after sewing are smooth, attractive, durable and not prone to damage.
Description
Technical field
The utility model relates to a kind of slide fastener, particularly relates to a kind of novel arc slide fastener.
Background technology
Slide fastener generally is the vertical bar shape, when being sewn on the arc opening place on the objects such as tent or case and bag when slide fastener, tangible fold can appear in the strap of the slide fastener that closes with the inner arc side seam, usually cut the clip of a plurality of inverted V-shapes in advance at the strap of inner arc, again strap and inner arc limit are sewed up after unnecessary fold is cut off.
But, the slide fastener after the stitching, the strap on the outer arc limit stretches tight tightlyer, and the strap on the inner arc limit is still not docile, and needs the scissors mouth before sewing up, and has cut the slide fastener of the edge of a knife and operate not only difficulty but also cracky when sewing up.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of more docile novel arc slide fastener of strap that is easier to sew up and sew up rear zipper.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of novel arc slide fastener comprises the outer arc strap, is arranged in outer arc sprocket, the inner arc strap on the outer arc strap and is arranged in inner arc sprocket on the inner arc strap that the space width of described outer arc sprocket is greater than the space width of inner arc sprocket.
The difference of the space width of described outer arc sprocket and described inner arc sprocket is 1.74mm-1.84mm.
The mean difference of the space width of described outer arc sprocket and described inner arc sprocket is 1.74mm-1.84mm.
Described outer arc sprocket is coarser than the inner arc sprocket slightly.
After adopting said structure, a kind of novel arc slide fastener of the utility model has following beneficial effect:
One, the space width of outer arc sprocket is greater than the space width of inner arc sprocket, after the drawing of arc slide fastener, and outer arc sprocket and the mutual interlock of inner arc sprocket, outer arc strap and inner arc strap are towards the bending of inner arc strap; Because slide fastener all adopts the ribbon with good extensibility, the outer arc strap can stretch naturally, and the inner arc strap can shrink naturally, and does not have tangible wave fold; When the arc slide fastener is sewed up at the arc opening place on objects such as tent or case and bag, needn't the scissors mouth directly with outer arc strap and inner arc strap corresponding outer ring and the inner ring place that is sewn to arc opening respectively, the stitching that makes the arc slide fastener is simple and effective more, outer arc strap after the stitching and inner arc strap are still very docile, not only attractive in appearance but also more durable, cracky not;
Two, as preferred embodiment of the present utility model, the outer arc sprocket is coarser than the inner arc sprocket slightly, after outer arc sprocket and the mutual interlock of inner arc sprocket, can strengthen the snap-in force of arc slide fastener, makes outer arc sprocket and inner arc sprocket can not throw off interlock easily.
Description of drawings
Fig. 1 is the structural representation of a kind of novel arc slide fastener of the present utility model.
Among the figure:
Inner arc strap 3 inner arc sprockets 4
Pull head 5
The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, a kind of novel arc slide fastener of the present utility model comprises outer arc strap 1, outer arc sprocket 2, inner arc strap 3, inner arc sprocket 4 and pull head 5.
After the drawing of arc slide fastener, outer arc sprocket 2 and the 4 mutual interlocks of inner arc sprocket, outer arc strap 1 and inner arc strap 3 are towards 3 bendings of inner arc strap; Because existing slide fastener all adopts the ribbon with good extensibility, outer arc strap 1 can stretch naturally, and inner arc strap 3 can shrink naturally, and does not have tangible wave fold.When the arc slide fastener is sewed up at the arc opening place on objects such as tent or case and bag, needn't the scissors mouth directly with outer arc strap 1 and inner arc strap 3 corresponding outer ring and the inner ring place that is sewn to arc opening respectively, make the stitching of arc slide fastener easier, the outer arc strap 1 after the stitching and inner arc strap 3 be very docile and more solid, cracky not still.
By selecting for use different between cog differences to adjust the radian size of arc slide fastener, if select for use the less between cog of 1.74mm, 1.76mm, 1.78mm poor, the radian after the drawing of arc slide fastener is just less and comparatively mild; Otherwise if select for use 1.80mm, 1.82mm, between cog that 1.84mm is bigger poor, the radian after the drawing of arc slide fastener is just bigger.
As preferred embodiment of the present utility model, outer arc sprocket 2 is coarser than inner arc sprocket 4 slightly, when the mutual interlock of outer arc sprocket 2 and inner arc sprocket 4, can strengthen the snap-in force of arc slide fastener, makes outer arc sprocket 2 and inner arc sprocket 4 can not throw off interlock easily.
Above-described embodiment and accompanying drawing and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
