Description

[Technical field]

[0001] The utility model relates to the technical field of zippers, in particular to a rope-threading pull tab and a zipper. [Background technology]

[0002] Pull tabs are also called zipper pieces, zipper tags or pull tags, and are mainly used in conjunction with zippers installed on clothing, bags, etc. In order to meet different usage requirements, pull tabs can generally be made of zinc alloy, copper, iron, plastic and other materials, and the surface can be formed into different styles by electroplating different colors, laser, silk screen, dripping glue and other methods.

[0003] At present, some pull tabs can also be provided with a drawstring, and the user can drive the pull tab by pulling the drawstring, thereby driving the zipper to realize the opening and closing functions; for example, the Chinese utility model patent with application number CN201520986969.0 discloses a pull tab and a pull head for a zipper. However, with regard to the installation of the drawstring, the common practice in the prior art is to make the pull tab body into a ring shape and directly tie the drawstring to the ring body of the pull tab. This installation method makes the knot of the drawstring protrude directly and be exposed to the outside, which is not only easy to wear or even damage during use, but also affects the appearance of the pull tab. In view of the above-mentioned problems, the inventor of this case conducted an in-depth study on this problem, and thus this case was created. [Utility Model Content]
