The invention relates to an electric anti-theft label, after a brushless motor is electrified, a winding stator in the motor generates an electromagnetic field to drive a magnetic rotor in the anti-theft label to rotate for unlocking, and a locking mechanism comprises a lock cylinder, a conical surface steel bowl at the top of the lock cylinder, an annular magnetic rotor fixedly sleeved outside the lock cylinder and a spring at the bottom of the lock cylinder. When the electric unlocking device is triggered, after a brushless motor is powered on, a winding stator in the motor generates a rotating electromagnetic field to drive an annular magnetic rotor located in the center of the magnetic field to rotate in the circumferential direction, due to the fact that a lock cylinder cannot rotate in the circumferential direction, and a protruding block and a cam part move, the lock cylinder is driven to move upwards, and then a cam is pressed to drive the lock cylinder to move downwards to compress a spring; when the protruding block moves to the position close to the wave crest, the lock cylinder downwards abuts against the unlocking position of the lower positioning base, and unlocking is conducted; and when the locking mechanism leaves the electric unlocking device or closes the electric unlocking device, power and excitation are lost, the lock cylinder is propped by the spring to reset, and the convex block naturally slides to the trough of the cam part to drive the annular magnetic rotor to reset.
本发明涉及一种电动防盗标签,利用无刷电机通电后,电机中绕线定子产生电磁场驱动防盗标签内部磁性转子转动开锁,所述的锁紧机构包括:锁芯、锁心顶部的锥面钢碗、锁心外套固的环形磁性转子、锁心底部的弹簧,触发电动开锁器时,利用无刷电机通电后,电机中的绕线定子产生旋转电磁场,驱动处在磁场中心位置的环形磁性转子周向转动,由于锁芯无法周向转动,凸块与凸轮部的移动,带动锁心向上移动,继而压迫凸轮带动锁芯向下移动压缩弹簧,当凸块移动至接近波峰处时,锁芯向下至抵顶下定位座的解锁位,开锁;当锁紧机构离开电动开锁器或关闭电动开锁器时,失电失磁,锁芯被弹簧抵顶复位,凸块自然滑落至凸轮部的波谷,带动环形磁性转子复位。
