Abstract

A double-lock structure includes a first module, a second module, a lock, at least one deflecting roller and a transmission element. The first module is installed at an end of a slide rail of each drawer. When one of the drawers is pulled open, other slide rails are linked and locked. The second module is installed on the first module for linking and locking the first module. The lock and the deflecting rollers are installed in a cabinet. An end of the transmission element is connected to the lock, and another end of the transmission element is passed through the deflecting rollers and then connected to the second module. When the lock is operated, the transmission element drives the second module and the first module to perform a drawer interlock to achieve a keylock effect, so as to reduce the manufacturing cost and provide both interlock and keylock functions.
