More Information
Summary:The utility model relates to zip-teeth of zipper comprising a zip-head and a couple of toothed edges. The utility model is characterized in that: the middle parts of the interior laterals of the couple of toothed edges are oppositely provided with positioning pins; the top ends of the couple of toothed edges are inward claw-like; the zip-head whose meshing surface is concave-circle shaped is hemisphere-shaped. The design of the positioning pins of the utility model guarantees the high flatly-fastening strength and the high single-tooth displacement force of the made-up zipper; the concave-circle shaped design of the meshing surfaces of the zip-teeth further guarantees the bending flexibility of the zip chain of the zipper with easily-sliding performance of meshing and splitting, as well as nicely solves the problem of the easily-sliding performance of the fastening and unfastening in the reverse direction.
