Motor driven blocking device

摘要

The arrangement has a locking bolt (4a) that can be moved linearly by an electric motor (2). A threaded sleeve (5) with an external thread mounted on the opposite end of the driven shaft from the motor interacts with an internally threaded nut (4) linearly movable in a housing (1) enclosing the motor and nut and connected to the locking bolt via an opening in the housing. Coil springs (3,3a) are arranged between the housing and nut to enclose the bolt within the housing and between the nut and motor to enclose the drive shaft.
