Document Type and Number:
WIPO Patent Application WO/2021/027282
Kind Code:
A1
Abstract:
Disclosed is a miniature smart lock with an anti-prising function, the miniature smart lock comprises a lock shell, and a magnetic rod, a push head, a bolt, a V-shaped push rod, an anti-prising guide slot, and a positioning guide pin, which are mounted in the lock shell, wherein a magnetic coil is mounted surrounding an outer portion of the magnetic rod; a magnetic rod spring is mounted on the magnetic rod on the left side of the magnetic coil; the push head is mounted at the right end of the magnetic rod; the V-shaped push rod is connected to the right end of the push head by means of a V-shaped push rod connection pin; and the V-shaped push rod is movably connected to the bolt by means of an anti-prising pin. The present invention is small in terms of size and has a simple structure, and is not restricted by the mounting environment. Electromagnetic driving is used such that the lock is unlocked when power is on and is locked when power is off, such that the lock is not affected by changes in temperature and is safe and durable. In addition, with the clever design of the positioning guide pin and the anti-prising guide slot, the positioning guide pin is located at the far left of a horizontal portion of the anti-prising guide slot during power-off locking, such that the bolt cannot bed directly lifted up for unlocking, thereby achieving the effect of being prising resistant and being safe and reliable.
