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 ( 4.4 b ) and a hook protrusion ( 4.4 a ), and the hook protrusion ( 4.4 a ) 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.
