A self-locking balance weight-type insulated glass assembly has two panes of glass with an inner cavity and a blinds assembly therein. The blinds assembly comprises a head rail, a slat assembly hung on the head rail, a bottom rail, a privacy fascia and a hollow side rail. The head rail has a hollow inner cavity with a rotary rod assembly and a rotary rod locking device therein. The slat assembly, the bottom rail and the rotary rod assembly are connected through a pull cord for controlling slats to rise or fall and a ladder cord for controlling the slats to turn. The rotary rod locking device has an end connected to the rotary rod assembly and an end connected to a gear box. An external magnetic operator is magnetically coupled to an internal magnetic operator arranged outside the inner cavity formed by the panes of glass.
