Quick-release replacement core buckle structure for lipstick shell

Abstract

This utility model discloses a quick-release replacement core buckle structure for lipstick cases, relating to the field of cosmetic packaging technology. The lipstick case buckle structure includes a bottom shell and a cover located above the bottom shell, as well as a mounting base assembly, an axial fastening assembly, a radial fastening assembly, an unlocking assembly, and a mounting base lifting assembly. This utility model, through a fastening device consisting of a vertically movable radial fastening plate, a horizontally extendable axial fastening plate, and an unlocking button, makes the disassembly and installation of the lipstick core simple and quick. Users only need to press the unlocking button to easily remove the lipstick core. When replacing the lipstick core, releasing the unlocking button allows the elastic reset component to automatically fasten the core, eliminating the need for tools and improving the user experience. The lipstick on this device is limited by the radial fastening plate in the radial direction, preventing shaking during use, while the double friction action in the axial direction solves the problem of lipstick easily falling off.
