ABSTRACT:
An improved door lock of a cargo container having a burglarproof function is disclosed. The door lock includes a handle hub, in which supporting pieces are integrally formed, welded to a locking rod, a rear supporting piece of the supporting pieces having a fastening hole, a front supporting piece of the supporting pieces integrated with an inward locking protrusion having a screw coupling groove, a handle including a connecting part and having a locking recess with a fastening hole such that the inward locking protrusion of the front supporting piece is inserted into and locked in the fastening hole due to pivot of the handle, and a bolt fastened into the screw coupling groove through the fastening hole of the rear supporting piece. Therefore, robbery is prevented and tamper-evident is easily checked during transfer of the cargo container so that measure against the tamper-evident can be easily taken.
