Anti-intrusion device for protecting traveling luggage in airport, has elastic unit constituted of spring displacing circular plate based on direction perpendicular to plane formed by plate for authorizing engagement of rollers

摘要

The device has four rollers of a strap (10) fixed on the device, and a circular plate (2) i.e. ratchet wheel, comprising a complementary unit (222) along the periphery of the plate at the roller for ensuring the mutual engagement of the rollers, when an elastic unit authorizes the engagement. The elastic unit constituted of spring (6) displaces the plate based on a direction perpendicular to the plane formed by the plate, and an exterior tube (7) is cooperated with the springs for exerting the force on the plate.
