Electronic cabinet/drawer lock system

摘要

An electronic wireless locking system comprising an external assembly and an internal assembly disposable on respective sides of a door or drawer. The external assembly includes a cover housing, a knob having a shaft, a card/credential reader, a status indicator, a wireless communication capability, a wire harness and a jump port plug. The internal assembly comprises a rotation link matable with the external shaft, a latch bolt, a circuit board and controller, and a locking mechanism including a rack and pinion gear set linking the rotation link with the latch bolt. A blocker inhibits the latch bolt from unlocking until authorized to rotate 90°, permitting the latch bolt to be withdrawn from a strike plate by manual rotation of the knob. An optional mechanical key override feature may also be provided. The system may further include a preload sensor and a device locked sensor.
