Abstract
The utility model relates to a nylon clamping slide fastener without core, which comprises a continuous repeatedly coiling single fastener(11) in the circle shape, a continuous repeatedly coiling single fastener(21) with the same structure as the single fastener(11), wherein, the single fastener(11) comprises a plurality of chain teeth(1) with the same structure, and the single fastener(21) comprises a plurality of chain teeth(2) with the same structure. The utility model is characterized in that: the middle parts of the circles above the chain teeth(2) and the chain teeth(1) are all provided with a groove(111) and(211). In order to make the fastener bars of the slide fastener be unlikely to be distorted caused by squeezing, and the middle parts of the circles under the chain teeth(2) and the chain teeth(1) are all pressed flat to form a flat wide edge(112) and(212), thereby the shape of the single fastener is very easy for keeping.
Description
Affiliated technical field
The utility model relates to a kind of commodity, especially a kind of need not heart yearn, but the nylon zipper of intensity height, long service life.
Background technology
Nylon zipper is seen everywhere in daily life, is widely used in industries such as clothes, handbag, case and bag, tent, footwear industry, family property, leatherware.
And the quality of slide fastener is mainly it in drawing with interlock degree and intensity when unclamping, that is to say, should prevent that the intensity after the drawing is not easy to break away from, and guarantees that again the chain after the drawing can unclamp because of the side direction pulling force.
The interlock degree of common above-mentioned slide fastener and the factor of intensity have two kinds, the thickness of used nylon yarn when one is the preparation chain, whether it two has heart yearn for the centre of sprocket, the thick more then intensity of general nylon silk is big more, but the words that nylon yarn is thick more, its pliability and deflection degree then can reduce, and the user feels that slide fastener is too hard and uncomfortable.And in sprocket, being provided with the nylon zipper of heart yearn, the nylon OK a karaoke club slide fastener that its intensity is not then established heart yearn is big.
The structure of the nylon zipper of 5#, 7# commonly used in the market as shown in Figure 1,8#, 9#, 10# belt carcass line is: a kind of nylon zipper, comprise a strap (9), a circle circle shape strand (11) that curls repeatedly continuously, one curl repeatedly continuously circle circle shape with the identical strand (21) of above-mentioned strand (11) structure, wherein, described strand (11) comprises the identical sprocket of some structures (1); Described strand (21) comprises the identical sprocket of some structures (2), is equipped with heart yearn (5) in the middle of described strand (11) and the strand (21) and passes through.
In the structure of above-mentioned nylon zipper, heart yearn (5) part that is absolutely necessary does not have heart yearn (5), and suture and strap are all fixed incessantly, thereby can landing, off-line causes slide fastener not have intensity, no practical value.
The inventor finds that there is following shortcoming in above-mentioned nylon zipper in the practice:
One, because the suture of above-mentioned nylon zipper generally is directly to be sewn on the heart yearn, when the folding slide fastener, suture can damage because rubbed, and influences the service life of slide fastener.
Two, because heart yearn is the indispensable part of above-mentioned nylon zipper, therefore the cost of above-mentioned nylon zipper is higher.
Summary of the invention
In order to overcome the above-mentioned shortcoming of existing nylon zipper, the purpose of this utility model is by changing the forming shape of nylon strand, cancel heart yearn, making the nylon zipper cost reduce 15-30%, reduce cost of labor and percent defective simultaneously, but the slide fastener quality can be guaranteed.
The technical scheme that the utility model adopted is: a kind of centreless nylon OK a karaoke club slide fastener, comprise a circle circle shape strand (11) that curls repeatedly continuously, one curl repeatedly continuously circle circle shape with the identical strand (21) of above-mentioned strand (11) structure, wherein, described strand (11) comprises the identical sprocket of some structures (1); Described strand (21) comprises the identical sprocket of some structures (2), and the mid portion that is positioned at the circle circle of described sprocket (2) and sprocket (1) top all is carved with a groove (111) and (211).
For the chain that makes described slide fastener is not easy to be out of shape because of extruding, the mid portion that is positioned at the circle circle of described sprocket (2) and sprocket (1) below flattens broadside (112) and (212) that form a flat.The shape of strand can well keep like this.
In order to increase the intensity of slide fastener, suture (6) on described sprocket (1) and (2) zipper cloth belt is fixing, this suture (6) is positioned at described groove (111) and (211), suture can play slide fastener is fixed on effect on the strap like this, can replace effect again, kill two birds with one stone with the reinforcement slide fastener intensity of original heart yearn.
The beneficial effects of the utility model are:
One, owing to make its distortion in the mid portion flanging of the upper surface of the sprocket of moulding chain, such two strands in conjunction with after, though the centre of two strands does not have heart yearn, two strands can not dwindle distortion because of being crowded together, and are convenient to sew up.After being sewn on the strap from recess chain, chain can closely link together automatically.
Two, owing in the positive cutting of mid portion of the lower surface of the sprocket of moulding chain, like this, during stitching, suture is sewed up along the line of rabbet joint, though there is not heart yearn, line can not slide, come off, and strap also just can be by firm fixing.Suture embeds and prolongs the service life that also can make slide fastener in the line of rabbet joint, because after embedding suture in the line of rabbet joint, the CONTACT WITH FRICTION of external force is less than the suture in the groove, and the life-span of suture obtains prolonging, thereby also obtains the service life of slide fastener prolonging.
Three, owing to omitted heart yearn in the structure of nylon zipper, and the intensity of slide fastener still can be guaranteed, and has saved the production cost of slide fastener.

The specific embodiment
As Fig. 2, Fig. 3, Fig. 4 and centreless nylon OK a karaoke club slide fastener shown in Figure 5, comprise a circle circle shape strand (11) that curls repeatedly continuously, one curl repeatedly continuously circle circle shape with the identical strand (21) of above-mentioned strand (11) structure, wherein, described strand (11) comprises the identical sprocket of some structures (1); Described strand (21) comprises the identical sprocket of some structures (2), it is characterized in that: the mid portion that is positioned at the circle circle of described sprocket (2) and sprocket (1) top all is carved with a groove (111) and (211).
For the chain that makes described slide fastener is not easy to be out of shape because of extruding, the circle circle mid portion that is positioned at described sprocket (2) and sprocket (1) below all flattens broadside (112) and (212) that moulding forms a flat.The shape of strand can well keep like this.
In order to increase the intensity of slide fastener, suture (6) on described sprocket (1) and (2) zipper cloth belt is fixing, this suture (6) is fixed in described groove (111) and (211), suture can play slide fastener is fixed on effect on the strap like this, can replace effect again, kill two birds with one stone with the reinforcement slide fastener intensity of original heart yearn.
