Abstract:
Provided is a novel multi-stage linked lock, comprising a primary lock and a pair of primary lock fasteners cooperating with the primary lock. The primary lock comprises a primary lock casing, a control mechanism, and a pair of primary lock cylinder components. The primary lock cylinder components and the control mechanism are both disposed within the primary lock casing. The pair of primary lock cylinder components are located at two sides of the control mechanism, respectively. The control mechanism is capable of synchronously controlling on-off states of both of the primary lock cylinder components. The primary lock fasteners are provided with multiple first protruding teeth matching the primary lock cylinder components. The novel multi-stage linked lock provided by the present invention enables easy closing by means of multi-stage linkage, a reduction gear is used for a push slider to further decrease a force required for moving a switch, and a feedback sound is generated by a spring when opening or closing, such that a user can clearly ascertain that the box has been closed properly.
