Lower zipper stopper and zipper

Abstract

A lower zipper stopper and a zipper. The lower zipper stopper comprises a lower stopper surface member (4) and a lower stopper bottom member (5). The lower stopper surface member (4) comprises a surface member cylinder (4.3), a hook (4.4) protrudes from an outer peripheral surface of the surface member cylinder (4.3), the hook (4.4) comprises a hook-shaped structure formed by a butt-joint between a guide rod portion (4.4b) and a hook protrusion (4.4a), and the hook protrusion (4.4a) is positioned at the bottom of the hook (4.4) in the axial direction. A main groove (5.3) is provided in the middle of the lower stopper bottom member (5), a bottom member guide protrusion (5.4) and a bottom member limiting protrusion (5.9) are arranged on an inner peripheral surface of the main groove (5.3), the bottom member guide protrusion (5.4) and the bottom member limiting protrusion (5.9) are sequentially arranged in the peripheral direction, and a guide channel (5.11) is formed between the bottom member guide protrusion and the bottom member limiting protrusion. During assembly, firstly, the lower stopper surface member (4) and the lower stopper bottom member (5) are axially aligned; then, the lower stopper surface member (4) and the lower stopper bottom member (5) rotate while axially moving until the lower stopper surface member and the lower stopper bottom member axially abut against each other; and finally, the lower stopper surface member (4) rotates, such that the hook (4.4) is snap-fitted with the bottom member limiting protrusion (5.9), thereby realizing axial limiting. The step of manually determining whether the lower stopper surface member (4) and the lower stopper bottom member (5) are connected in place can be omitted, and use is facilitated.
