Abstract
The utility model discloses a popout-proof zipper with a counter vane. The zipper comprises a zipper left loop, a zipper right loop and a double teeth zipper head. The double teeth zipper head is provided with a zipper column. The counter vane is fixedly connected with the middle portion of the zipper column and the counter vane is integrally formed with the zipper column. Left lower layer teeth and left upper layer teeth are respectively fixed at the edges of the upper side and the lower side of a left side woven belt and form a left groove. Right upper layer teeth and right lower layer teeth are respectively fixed at the edges of the upper side and the lower side of a right side woven belt and form a right groove. The left portion of the counter vane is matched with the left groove and the right portion of the counter vane is matched with the right groove. The direction of the teeth of the left lower layer teeth and the right lower layer teeth and the direction of the teeth of the left upper layer teeth and the right lower layer teeth are designed reversely.
