Electromechanical locking device

An electromechanical barrier device for a closure element or for a switching element comprising:

• a stator and
• a rotor, wherein the rotor is mounted in the stator,
• wherein
• the barrier device comprises an extension element, wherein the extension element is moved in an axial direction between an insertion position and a removal position,
• wherein the barrier device comprises a barrier element, wherein in a first position, the barrier element prevents the rotor from being rotatable relative to the stator, wherein in a second position, the barrier element enables the rotor to be rotatable relative to the stator,
• wherein the barrier device comprises a blocking element, wherein in a release position, the blocking element allows the movement of the barrier element from the first position into the second position and in a blocking position, prevents the movement of the barrier element from the first position into the second position, wherein an actuator serves to enable a movement of the blocking element from the blocking position into the release position, and
• wherein a starting position and the release position is assumed by the blocking element, wherein the extension element and the blocking element are designed such that the extension element in the removal position allows a movement of the blocking element from the release position into a blocking position, into the starting position.
