Electromagnet opening device for deposit box or safe box
Disclosed is an electromagnet opening device for a deposit box or a safe box, comprising a housing body (1). The housing body (1) is provided with a fixed iron core (2), a movable iron core (3), an electromagnetic coil (4), a toggle piece (5) and a closed spring (6) therein, wherein the bottom of the movable iron core (3) is fitted with the fixed iron core (2) and is sheathed on a top end thereof by a shaft sleeve (8), and the shaft sleeve (8) extends to an outer side of the housing body (1) via through holes on the housing body (1). A vibration sensing mechanism (7) is also provided in the housing body (1), comprising a sensing block and a balance spring (9), wherein a blocking terminal (10) and a balance terminal (11) are provided on the sensing block, and the two are respectively located on two sides of the movable iron core (3); the balance spring (9) is provided between the bottom of the balance terminal (11) and the housing body (1); the bottom of the blocking terminal (10) is connected with the housing body (1) via the rotatory connection of a rotating shaft (12); when the sensing block is rotated by the rotating shaft (12) to compress the balance spring (9), the blocking terminal (10) abuts against the bottom surface of the shaft sleeve (8). The opening device prevents the shaft sleeve (8) of the movable iron core from accidentally contracting through the addition of the vibration sensing mechanism (7), which effectively prevents the deposit box or the safe box from abnormally opening.
