Abstract
A double self-lock slide fastener comprises a slide fastener body, a pulling chip, a lock core, and a nut cap. The slide fastener body provides an upper wing plate, a lower wing plate and a sprocket guide groove limited by the upper and lower wing plates, the front ends of the upper and lower wing plates connect to one body by a chain tooth guide pole, the wing plate whose tail end is in a rectangular figure and whose head expands outward is in a Y shape, a pair of flanges are provided along the sides which are opposite to the tail ends of the upper and lower wing plates, the flanges extend upward to the middle part of the expansion heads of the upper and lower wing plates from the starting part of the expansion heads. By extending the length of the flanges in the sides of the upper and lower wing plates, the flanges can be blocked between the chain teeth, then the slide fastener is fixed and another self-lock function is realized besides the existing self-lock function of the lock core, therefore, the self-lock strength of the slide fastener is reinforced and the reliability of the slide fastener self lock is guaranteed.
Description
Technical field
The utility model relates to a kind of slider of zipper fastener, refers in particular to a kind of slider of zipper fastener with two auto-lock functions.
Background technology
Existing slider of zipper fastener, constitute by slider of zipper fastener body, pulling-on piece, lock core and block, wherein, the slider of zipper fastener body is provided with the sprocket gathering sill of lower wing plate and qualification thereof, last lower wing plate front end connects one by the sprocket lead, it is the Y shape shape that rectangle, head expand outwardly that wing plate is tail end, until the head section start that last lower wing plate expands outwardly, respectively is provided with pair of flanges along last lower wing plate tail end opposed side edges.The slide fastener of this structure only possesses a kind of self-locking mode of lock core self-locking, and lock core when promptly pulling-on piece unclamps inserts between the chain tooth under the effect of block inner shrapnel, and pull head is fixed.Bear during the lock core self-locking retaining power for stress point, when lock core inserted the chain tooth, the self-locking brute force that institute can bear was limited, when the pulling force that can bear above lock core, then pull head loses self-lock ability.Especially when slide fastener was subjected to lateral pull, two chain interbands had produced certain angle, and flange can not block the chain tooth, and slider of zipper fastener reduces or the forfeiture auto-lock function in the case.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of slider of zipper fastener with two self-lock abilities is provided, being about to upward, the flange of lower wing plate side edge extends upward, when making slide fastener be subjected to lateral pull, flange can be stuck between chain tooth and the chain tooth, slider of zipper fastener is fixed, realize another place's lock function that slider of zipper fastener core auto-lock function is outer, specifically be achieved like this: the slider of zipper fastener of two self-lockings, by the slider of zipper fastener body, pulling-on piece, lock core and block constitute, wherein, the slider of zipper fastener body is provided with the sprocket gathering sill of lower wing plate and qualification thereof, and last lower wing plate front end connects one by the sprocket lead, and it is rectangle that wing plate is tail end, the Y shape shape that head expands outwardly, it is characterized in that the pair of flanges that is provided with along last lower wing plate tail end opposed side edges, the head section start that is expanded outwardly by last lower wing plate extends upwardly to the middle part of this expanded head.
The utility model is provided with flange, and the flange on last lower wing plate head side limit has the head side edge lengths more than 1/5th at least, and best length is 1/3rd to 2/3rds head side edge lengths.
In order to prevent that the blocked up card of thickness of flange from not advancing between the chain tooth, the width of flange of the present utility model is less than the gap of chain tooth and chain tooth.
By prolonging the flange length that goes up the lower wing plate side edge, make a chain in use, except that original core auto-lock function, flange can also be stuck between chain tooth and the chain tooth, slider of zipper fastener is fixed, realize another auto-lock function, thereby strengthened slider of zipper fastener self-locking brute force, guarantee the reliability of slider of zipper fastener self-locking.

The specific embodiment
The slider of zipper fastener of two self-lockings, by slider of zipper fastener body 1, pulling-on piece 2, lock core 3 and block 4 constitute, wherein, slider of zipper fastener 1 body is provided with lower wing plate 11,12 and the sprocket gathering sill that limits, last lower wing plate front end connects one by the sprocket lead, it is rectangle that wing plate is tail end, the Y shape shape that head expands outwardly, pair of flanges 5 along last lower wing plate tail end opposed side edges setting, the head section start that expands outwardly from last lower wing plate extends upwardly to the middle part of this expanded head, be that flange on the head side will have the head side edge lengths more than 1/5th at least, a head side edge lengths of/3rd to 2/3rds preferably, the width of flange is less than the gap of chain tooth and chain tooth, so that slide fastener is when being subjected to lateral pull, flange can be stuck between chain tooth and the chain tooth, and slider of zipper fastener is fixed, and realizes another outer auto-lock function of slider of zipper fastener core auto-lock function.
Claims (4)
1. the slider of zipper fastener of two self-lockings, constitute by slider of zipper fastener body, pulling-on piece, lock core and block, wherein, the slider of zipper fastener body is provided with the sprocket gathering sill of lower wing plate and qualification thereof, last lower wing plate front end connects one by the sprocket lead, it is the Y shape shape that rectangle, head expand outwardly that wing plate is tail end, it is characterized in that the pair of flanges that is provided with along last lower wing plate tail end opposed side edges, and the head section start that is expanded outwardly by last lower wing plate extends upwardly to the middle part of this expanded head.
2. according to claim 1 pair of self-locking slider of zipper fastener is characterized in that flange on last lower wing plate head side limit has the head side edge lengths more than 1/5th at least.
