Title:
SELF-LOCKING STRUCTURE APPLIED TO LOCK
Document Type and Number:
WIPO Patent Application WO/2022/120628
Kind Code:
A1
Abstract:
A self-locking structure applied to a lock, comprising a lock bolt (1), a lock bolt spring (2), a limiting assembly (3), a worm (4), a driving device (5) and a slider (6), wherein the lock bolt spring (2) is arranged opposite to the lock bolt (1) and is used to push out the lock bolt (1) so as to limit a lock tongue (7); the limiting assembly (3) is disposed at the axial end of the lock bolt (1), and is used to limit the lock bolt (1) to prevent retraction; the worm (4) is perpendicular to the lock bolt (1); the driving device (5) is used to drive the worm (4) to rotate; and the slider (6) is engaged with the worm (4) and touches the limiting assembly (3), the rotation of the worm (4) drives the slider (6) to move along the axial direction of the worm (4), and the movement of the slider (6) pushes the limiting assembly (3) so as to release the limiting of the lock bolt (1). By means of the cooperation of the worm (4) and the slider (6), the slider (6) is limited by using a self-locking principle of the worm (4), and then the purpose of limiting the lock bolt (1) is achieved by means of the the slider (6) limiting the limiting assembly (3) to form a self-locking function inside the lock. As long as the driving device (5) does not work, the slider (6) is in a locked state, thereby eliminating the risk of an electronic lock being unlocked by being hit, and truly achieving the anti-collision security of the electronic lock.
