Magnetic fastening buckle

Abstract

A magnetic fastening buckle includes a male and a female buckle member that can be moved toward and engaged with each other by magnetic attraction between two magnets separately provided thereon; and an anti-separation member movably connected to the male buckle member. When the anti-separation member is located at an unlocking position, it does not overlap the female buckle member, allowing the male buckle member to move rearward in a y-axis direction to separate from the female buckle member. When the anti-separation member is moved in an x-axis direction to a locking position, it can overlap the female buckle member. In this position, the anti-separation member can overlap the female buckle member when the male buckle member is pushed toward a rear removal opening, so as to prevent the male buckle member from separating from the female buckle member, allowing the two buckle members to remain engaged with each other.
