Abstract: The present invention provides an electronic lock structured to include a first bolt configured with an elastic clasp, an electromagnetic device connected to an input device, a second bolt and a microswitch connected to a security system, all of which are installed interior of a housing of the electronic lock. The elastic clasp is retained by a protruding edge of the housing, thereby disenabling the first bolt from an arbitrary retracting movement that would otherwise render the lock incapable of being unlocked. The input device controls the electromagnetic device to induce the elastic clasp and release a retaining state, and then directly rotating a rotating button causes a retracting movement of the first bolt and unlocking of the electronic lock, which simultaneously disconnects the security system.

Abstract: An anti-theft latch is proposed. The anti-theft latch has a movable stud having a driven means therein. A pin serves to connect the movable stud with the driven means. The driven means is pivotally installed with a static latch. A guide groove is formed on the static latch. The pin is matched with the guide groove. The guide groove of the static latch is formed with a buckling portion. When the movable stud is to be unlocked by an outer force, the pin will eject and buckle the buckling portion so that the static latch can not retract to the movable stud to achieve an effect of statically locking. An auxiliary spring is further installed for pushing the driven means to move forwards. Therefore, in a normal condition, the static latch will achieve an effect of statically locking. As a result, the thief has no possibility to unlock the movable stud to move inwards and therefore, a preferred anti-theft effect is achieved.
