Abstract
The utility model discloses a zipper head with a dismountable zipper pull and comprises a zipper head body, a zipper pull and a horse hook. A pulling nose is formed on an upper sliding plate of the zipper head body, the horse hook is covered on the pulling nose, and groove walls on two sides of a hinge end of the horse hook are hinged with the root of the pulling nose. An elastic piece bending and extending towards the root of the pulling nose is formed on the hinge end of the horse hook. The inner lateral side of the horse hook elastic piece and the groove bottom of an accommodating groove of the pulling nose are both arranged into involute curved surfaces involuting along the extending direction of the elastic piece. Mutual interference between the inner lateral side of the elastic pieces and the groove bottom of the accommodating groove is adopted to force the elastic piece to swing and deform, and simultaneously the accommodating groove forms a concave space to accommodate rotation of the elastic piece, thereby avoiding extruding deformation of the elastic piece in the length direction. Compared with existing zipper heads with the dismountable zipper pull, the zipper head with the dismountable zipper pull reduces deformation range of the horse hook elastic piece, avoids easily-arising metal fatigue problem, and prolongs service life of the zipper head.
