SEMICIRCULAR ZIPPER TOOTH
Document Type and Number:
WIPO Patent Application WO/2019/041486
Kind Code:
A1
Abstract:
A semicircular zipper tooth, comprising a first meshing surface (1) and a second meshing surface (2); the surfaces of the first meshing surface (1) and the second meshing surface (2) are recessed inward facing a zipper tooth body to form a first meshing concave portion (3), a second meshing concave portion (4), and a meshing portion (5); the outer contours of the side surfaces of the first meshing surface (1) and the second meshing surface (2) are fan-shaped; the central angles of the circular arc segment of the outer contour of the first meshing surface (1) and the second meshing surface (2) are greater than or equal to 90 degrees; the width of the outer contour of the end face of the meshing portion (5) is gradually reduced from a positioning groove (8) to the two ends of the meshing portion (5); by changing the structure of the meshing portion (5), under the action of various external forces, and particularly, under the action of "U"-shaped squeezing forces, zipper teeth are meshed with each other more tightly and are not easy to separate.
