Abstract
The invention discloses a zipper capable of preventing a zipper puller from falling off. A left saw-tooth-shaped clamping tooth is arranged at the upper left ends of left chain teeth. A right saw-tooth-shaped clamping tooth is arranged at the upper right ends of right chain teeth. A round concave hole is formed in the upper left end of a sliding block. A short through square hole is formed in the bottom end of the round concave hole in the axial direction. A check ring is arranged on the upper portion of the round concave hole. A cylinder, a compression spring, a round baffle and a square clamping tongue are arranged in the round concave hole. The square clamping tongue is inserted into the short square hole downwards under the elastic force effect of the compression spring and clamps the left clamping tooth. A round through hole is formed in the upper portion, extending out of the check ring upwards, of the cylinder in the radial direction. A rotating shaft is arranged on the lower left portion of a pull ring and inserted into the round through hole in the upper portion of the cylinder leftwards. By the adoption of the structure, when pulled upwards, the zipper puller will not move downwards even under the effect of external force, so that the embarrassment phenomenon that the zipper puller falls off is avoided.
Description
Technical field
The present invention relates to slide fastener technical field, especially a kind of slide fastener that can prevent chain-taking.
Background technology
The purposes of slide fastener is extremely extensive. The defect that traditional slide fastener exists is: when slider of zipper fastener is upwards pulled on, at the work of external forceMove down with lower meeting, cause common chain-taking phenomenon, very awkward while particularly there is chain-taking on trousers.
Summary of the invention
The object of this invention is to provide a kind of slide fastener, when slider of zipper fastener is upwards pulled on, can be not downward under the effect of external force yetMobile, thus avoid occurring the embarrassing phenomenon of chain-taking.
Technical scheme of the present invention is: manufacture and design a kind of slide fastener that can prevent chain-taking, comprise left chain band, right chain band andSlider of zipper fastener, is respectively equipped with left chain tooth and right chain tooth on described left chain band and right chain band, described slider of zipper fastener comprises draw ring, slide block, cunningThe left seam gap of groove and chute arranged on left and right sides and right seam gap, it is into a single integrated structure that described draw ring is movably connected in upper end of slide block middle partProtuberance on, main feature of the present invention is: the left upper end of described left chain tooth is respectively equipped with into one with the upper right side of right chain toothThe jagged left latch of body structure and right latch, described left latch is identical with the crown direction of right latch.
The left upper end of described slide block is provided with round shrinkage pool, and the bottom of described round shrinkage pool is provided with the short square hole communicating vertically,The top of circle shrinkage pool is provided with back-up ring, and described back-up ring adopts strong viscose glue to be adhesively fixed and fixes on the hole wall of round shrinkage pool.
In described round shrinkage pool, be provided with cylinder, sheathed Compress Spring on the external diameter end of described cylinder, the lower end of cylinder is provided withInto a single integrated structure circular baffle plate, the lower end of described circular baffle plate is provided with into a single integrated structure square block tongue, described square block tongueUnder the elastic force effect of Compress Spring, insert in short square hole downwards and block left latch.
The top that described cylinder protrudes upward back-up ring is radially provided with round tube hole.
The lower left quarter of described draw ring is provided with into a single integrated structure rotating shaft, and the flexible of cylinder top inserted in described rotating shaft leftIn hole, be pulled upwardly draw ring, mention square block tongue by rotating shaft, slide block can be moved flexibly on left chain tooth.
Draw ring is pulled upwardly while pulling slider of zipper fastener, mentions square block tongue by rotating shaft, make the slide block can spirit on left chain toothLive mobile; Unclamp after draw ring, square block tongue inserts in short square hole downwards and blocks left latch under the elastic force effect of Compress Spring,Slide block cannot be moved flexibly on left chain tooth, even under the effect of external force, slider of zipper fastener also can not move down.
The present invention, owing to adopting said structure, when slider of zipper fastener is upwards pulled on, also can not move down under the effect of external force,Thereby avoid occurring the embarrassing phenomenon of chain-taking.
