Abstract

A locking device comprises a lock body having a through hole, a bolt member having a longitudinal bore therethrough and an insertion end which is inserted into the through hole of the lock body. The bolt member is further having a retaining pin disposed within the longitudinal bore and a resilient means for biasing the retaining pin axially out of the longitudinal bore. When the bolt member is inserted into the lock body, a means within the lock body prevents the removal of the inserted bolt member therefrom, and engages an actuating means to actuate an identifying means. The identifying means transmits a signal to indicate whether the locking device has been tampered with or defeated. If the bolt member is cut, the retaining pin is displaced out of the longitudinal bore and dislodges theactuating means resulting in the identifying means indicating that the locking device has been tampered with or defeated.

Description

technical field [0001] The present invention relates to a locking device that can indicate and notify users whether the locking or safety seal is broken, especially a locking device for locking ocean-going containers, truck trailers, trucks, equipment cabinets, electric gates, etc. Background technique [0002] Locking seals or security seals are used to prevent vandalism and unauthorized access or manipulation of various forms of articles. Examples of items utilizing lock seals or safety seals include doors of ocean containers, truck trailers, vans, equipment cabinets, high voltage switchgear, etc. [0003] One common seal consists of a metal stud, or flexible cable, with a head at one end and a hard tip at the other; and a lock body to receive either the end of the metal stud or the hard tip of the flexible cable. Once one end of the metal bolt or the hard tip of the flexible cable is inserted into the lock body, the metal bolt or the hard tip is held by a locking mechani...
