Title:
ROTATIONAL FASTENING STRUCTURE, SNAP FASTENER, AND ASSEMBLY METHOD AND ASSEMBLY TOOL FOR ROTATIONAL FASTENING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/232915
Kind Code:
A1
Abstract:
A rotational fastening structure and a snap fastener comprising the rotational fastening structure, and an assembly method and an assembly tool. The rotational fastening structure (10) comprises a face piece (110) and a rotational bottom piece (120) fastened to the face piece (110). The face piece (110) comprises a face piece main body (111), a non-cylindrical protrusion (112), and a T-shaped limiting piece (113). The non-cylindrical protrusion (112) is connected to the face piece main body (111), the vertical part (113a) of the T-shaped limiting piece (113) is connected to the non-cylindrical protrusion (112), and snap slots (113c) are provided both ends of the horizontal part (113b) of the T-shaped limiting shape (113). The rotational bottom piece (120) comprises a bottom piece main body (121) provided with a mounting hole (121a) and limiting stepped platforms (122) arranged symmetrically on the inner surface of the mounting hole (121a), protruding blocks (123) matched with the snap slots (113c) being provided on the limiting stepped platforms (122), and a through channel (124) being provided in between the two limiting stepped platforms (122). When the vertical part (113a) of the T-shaped limiting piece (113) is inserted into the mounting hole (121a), the horizontal part (113b) passes through the through channel (124). The bottom piece main body (121) is used to drive the protruding blocks (123) to rotate relative to the horizontal part (113b) of the T-shaped limiting piece (113) under an external twisting force, and thus embed the protruding blocks (123) in the snap slots (113c).
