ELECTROMAGNET OPENING DEVICE FOR DEPOSIT BOX OR SAFE BOX
The present invention is an electromagnet opening device for a safe deposit box or safe box, comprising: a housing (1), a fixed iron core (2), a movable iron core (3), an electromagnetic coil (4), a paddle (5) and a closed spring (6) disposed in the housing (1). The movable iron core (3) has a bottom end engaging with the fixed iron core (2). A shaft sleeve (8) is configured to sleeve a top end of the movable iron core (3) and extends outside of the housing (1) through a through hole in the housing. A vibration sensing mechanism (7) is disposed in the housing (1) and comprises a sensing block and a balance spring (9). The sensing block has a stopping end (10) and a balancing end (11) located on two sides of the movable iron core respectively, and the balance spring (9) is disposed between the balancing end (11) and the housing (1). A bottom of the stopping end (10) is rotationally connected onto the housing (1) through a rotation shaft (12), and when the sensing block compresses the balance spring (9) through a rotation of the rotation shaft (12), the stopping end (10) is driven to abut against a bottom surface of the shaft sleeve (8). The vibration sensing mechanism (7) effectively prevents a mistaken shrinkage of the shaft sleeve of the movable iron core (8) and abnormally opening of a safe deposit box or a safe box.
