Abstract

The utility model relates to a theft-protection zipper which can prevent the zipper from being undone without zipper pull; the utility model comprises a zipper pull, a pull guillotine, a U-shaped groove which allows the chain teeth of the zipper (right) running inside the zipper pull, a big gap is arranged on the left side of the zipper which allows the right chain teeth being accessed in 45 degrees angle, the left zipper chain teeth which slip towards the sliding groove of chain teeth head is also arranged at the left side of the zipper, a circular chain teeth head is arranged on the right side of the chain, the necking of the chain teeth head is a minute cone connected with the root of the chain teeth head and circular or oblong chain teeth head is fixed on the right chain teeth of the right chain body; when the zipper pull is pulled downward, the inner pull guillotine hilt of the zipper pull can separate when the chain teeth at the right side of chain teeth inside U-shaped groove in the zipper pull and the left chain teeth form 45 degrees angle; when the zipper pull is pulled upward, the chain guillotine of the zipper pull can access the right chain teeth at the right side of the U-shaped groove in the zipper pull from the opening of left chain teeth, enters into the left necking movable mouth of right chain teeth head sleeved inside the left chain teeth head of the left chain teeth head part along the slide groove and then ensures the chain teeth at both sides are well-toothed along the running of the zipper head.

Description

Antitheft zipper

Affiliated technical field:

The novel chain that relates to a kind of slide fastener of this implementation closes structure, can prevent that especially slide fastener from not pried open through slider of zipper fastener.

Background technology:

At present, known slide fastener be by slider of zipper fastener two row's parallel corresponding engagements of zipper sprocket and play the chain cooperation and use, wherein giving the track that sprocket slides in the slider of zipper fastener also is the plane operation.

Summary of the invention:

In order to overcome the deficiency that existing slide fastener also can be pried open without begin chain, the utility model provides a kind of Antitheft zipper, and the right takes the shape of the letter U for the track of sprocket process in this Antitheft zipper slider of zipper fastener.

The technical scheme that its technical problem that solves the utility model adopts is:

There have track for the right sprocket process to take the shape of the letter U in the right begin chain body of the hinge head cutter in the middle of the slider of zipper fastener to be crooked, so as the sprocket on slide fastener the right through U-rail the time, be 45 ground cooperate on the right of sprocket enter in the sprocket channel of the left side; The sprocket root on the left side has a big opening that is pot shape, big opening leads to sprocket head inside a groove, this groove divides inside groove and water jacket, the sprocket head that inside groove just reaches slide fastener the right passes through, water jacket just enough under the sprocket head of slide fastener the right tiny neck pass through, and the through sprocket crown of this groove end can be arranged in the sprocket on the left side on the slide fastener serobila when excessive opening and run channel enter the sprocket head abreast than convenient the right sprocket; The sprocket head on the right is the major part of a circle, and big subfacies is a bit of tiny cylinder, and the root of sprocket to be the major part of a circle or square be fixed on the slide fastener body on the right.The big opening part of parallel like this right and left sprocket, in slider of zipper fastener, just be the contact of 45 in the U groove on the right, at this moment this sprocket head of left state is the big opening part of sprocket on the right just, in the sliding back and forth of slider of zipper fastener, the chain side tool cutter hinge head cutter of slider of zipper fastener two sides is just finished the on and off of slide fastener body to the zipper teeth on both sides in the U-lag on slider of zipper fastener the right.

The beneficial effects of the utility model are: can prevent that slide fastener just be not opened through slider of zipper fastener.

The specific embodiment

In Fig. 2, slider of zipper fastener (7) is when gliding, and the interior hinge head cutter of slider of zipper fastener (7) (1) is separating hinge head cutter place in slider of zipper fastener with the sprocket (2) on the left side for the sprocket (1) on the right in the U-lag (12) of the right sprocket process when being 45;

When slider of zipper fastener (7) when upwards drawing, the chain side tool (6) of slider of zipper fastener (7) two sides just hinge head cutter place in slider of zipper fastener during for the U-lag (12) of the right sprocket process the sprocket (1) on the right insert from the big opening part of left side sprocket (2), and enter left side sprocket head along slide slot (14), for overlapping in the on the left side sprocket head, the right sprocket Head and Neck movable port (15) keeps the parallel engagement of both sides sprocket along the operation of slider of zipper fastener (7) again.

Claims
