Abstract
The utility model discloses a waterproof zipper. The outsides of cloth strips and a closed opening are all coated with a waterproof layer. A press plate is arranged between an upper boat plate and a lower boat plate of a zipper head. The cloth strips and zipper teeth are clamped between the upper boat plate and the lower boat plate. The press plate is inserted between the cloth strips and the zipper teeth. The widths of the covering and connecting parts of the cloth strips of both sides are respectively larger than the widths of the zipper teeth of both sides. Pull connecting openings are arranged on the lower bottoms of the inner bottom surfaces of the cloth strips and are coated with a waterproof layer. Closed type elastic sealing rings which are convexly arranged on the cloth strips are formed by that the covering and connecting parts of the upper bottoms of the outer bottom surfaces of the cloth strips are respectively connected with the cloth strips of both sides. The lower bottoms of the pull connecting openings and the closed type elastic sealing rings are tightly clamped between the upper boat plate and the lower boat plate of the zipper head. When the waterproof zipper is pulled together, the covering and connecting parts of the cloth strips can form an arched clamping part under the action of limited plates of both sides of the upper boat plate of the zipper head. The zipper head can be pulled to the closed type elastic sealing rings which can separate with the zipper teeth and clamp the upper bottoms and the lower bottoms of the pull connecting openings. The zipper teeth can realize complete mesh, and the pull connecting openings can be sealed completely. The utility model has good waterproof effect.
Description
Technical field
The utility model relates to a kind of waterproof slide fastener.
Background technology
General slide fastener comprises strap, slide fastener tooth, slider of zipper fastener, close mouth and the corresponding drawing mouth that is positioned at the slide fastener other end with close mouth, and slider of zipper fastener is provided with the deck of boat and the following deck of boat, and the both sides of the upper and lower deck of boat are respectively equipped with limiting plate.
Existing waterproof slide fastener comprises strap, slide fastener tooth, slider of zipper fastener, close mouth and drawing mouth, is coated with watertight composition on the strap, and the appearance bread of slide fastener tooth and close mouth is marked with waterproof sealing layer.But the waterproof slide fastener of this structure, when slide fastener was moved terminal point to, the front end of slider of zipper fastener only flushes and still has part slide fastener tooth to be positioned at slider of zipper fastener with the drawing mouth did not have interlock, and waterproof effect is relatively poor.
The utility model content
The purpose of this utility model provides a kind of waterproof effect waterproof slide fastener preferably.
The technical solution of the utility model is such: waterproof slide fastener, comprise strap, slide fastener tooth, slider of zipper fastener, close mouth and drawing mouth, be coated with watertight composition on the strap, the appearance bread of close mouth is marked with watertight composition, and inner bottom surface and both sides strap that both sides slide fastener tooth is sutured in the both sides strap respectively are respectively equipped with the portion that covers that covers the slide fastener tooth; The upper bottom portion that the lower bottom part that above-mentioned drawing mouth is positioned at the strap inner bottom surface is coated with watertight composition, be positioned at the strap outer bottom links to each other respectively with the portion of covering of above-mentioned both sides strap and forms the closed elastic seal ring that is convexly set on the strap, and the lower bottom part of above-mentioned drawing mouth and above-mentioned closed elastic seal ring closely are located in up and down between the deck of boat of above-mentioned slider of zipper fastener; The width of the portion that covers of above-mentioned both sides strap is respectively greater than the width of both sides slide fastener tooth; Above-mentioned strap and above-mentioned slide fastener tooth are located between the upper and lower deck of boat of above-mentioned slider of zipper fastener, and are provided with the pressing plate that is inserted between above-mentioned strap and the above-mentioned slide fastener tooth between the upper and lower deck of boat of above-mentioned slider of zipper fastener, and this pressing plate is most advanced and sophisticated corresponding to an end of close mouth.
Above-mentioned each watertight composition is a rubber layer.
Above-mentioned elastic seal ring is the rubber v shaped ring.
The utility model waterproof slide fastener, strap is coated with watertight composition, the close mouth bag is marked with watertight composition, slider of zipper fastener is located in strap and slide fastener tooth between the upper and lower deck of boat, and pressing plate is inserted between strap and the slide fastener tooth, because the width of the portion that covers of both sides strap is respectively greater than the width of both sides slide fastener tooth, during drawing, the interlock under the effect of the pressing plate and the following deck of boat of slide fastener tooth, the portion that covers of strap forms the sandwich part that arches upward under the effect of the both sides of the deck of boat on slider of zipper fastener limiting plate, play waterproof effect.When slider of zipper fastener arrived slide fastener tooth terminal, slider of zipper fastener can continue pulling, breaks away from the slide fastener tooth until slider of zipper fastener and clamps the closed elastic seal ring of drawing mouth lower bottom part and upper bottom portion, and complete interlock of slide fastener tooth and drawing mouth be sealing fully also, and waterproof effect is better.
