The invention provides a computer key unlocking device, which includes a housing, an unlocking lever, a locking shaft, a moving part and an unlocking module part. The unlocking lever includes a main body and a head; The connecting piece, the electromagnet and the push-pull rod that can enter and exit along its axial direction; the unlocking module part is used to send a signal to the electromagnet, thereby driving the push-pull rod to move away from the unlocking rod and magnetically attracting the unlocking pin to move away from the unlocking Movement in the direction of the rod switches the locking shaft from a rotationally restricted state to a freely rotating state. Since the electromagnet and the push-pull rod are not directly involved in the locking / unlocking action of the locking shaft movement, the phenomenon that the electromagnet is damaged by external force and the unlocking mechanism cannot be normally unlocked is avoided.
Description
technical field [0001] The invention relates to the field of anti-error locking of substations, in particular to a computer key unlocking device. Background technique [0002] Most of the existing computer keys use electromagnet push-pull rods to lock / unlock the movement of the unlocking mechanism, and the implementation methods are divided into direct and indirect two types. The former uses the electromagnet push-pull rod to directly bear the torque of the unlocking mechanism, and the torque directly acts on the push-pull rod during forced unlocking, which is easy to cause damage to the push-pull rod and the rotating shaft in contact with it and affect the smoothness of the unlocking operation. Compared with the direct type, the indirect unlocking mechanism structure uses indirect components instead of electromagnet push-pull rods to receive torque. If the unlocking structure has a complex structure, the size will increase, thereby increasing the power consumption of the el...
