Patent attributes
A mechanical-magnetic locking device includes a first connecting component, a second connecting component and a magnet-armature structure. The first connecting component is provided with a locking element with a gap. The second connecting component is provided with a locking member matched with the locking element with the gap. A magnet is provided in one connecting component and an armature is provided in the other connecting component. The locking element with the gap is coupled with the magnet and the armature is coupled with the locking member. When opening the locking device, the magnet and the armature are relatively moved to each other, and the magnetic attracting area is substantially unchanged or increased, allowing the locking element with the gap and the locking member to move from the engaged position to the non-engaged position.
