The present invention discloses an improved louver turning mechanism and a hollow glass door or window with a built-in magnetically controllable louver, comprising a turn traction member, a turn transmission member and a slat turning member which are connected in turn, wherein the turn transmission member comprises a slat turning wheel and a joint interlocking mechanism which are used in cooperation, the joint interlocking mechanism is, at one end thereof, eccentrically fixedly connected to the slat turning wheel to drive it to rotate, and, at the other end thereof, connected to the turn traction member through a connecting push rod; the slat turning wheel is coaxially fixedly connected to a horizontal rotation shaft of the slat turning member. According to the present invention, the slat turning wheel and the joint interlocking mechanism are used in cooperation to substitute a pull-cord transmission mechanism and a gear transmission mechanism. The present invention is structurally more compact and reasonable. The louver can act more precisely and reliably and be turned at a larger angle so that the slats of the louver can abut against one another more closely. The louver exhibits advantages such as a closer abutment of slats, a better sunshade performance, a longer service life, stable and reliable use, unlikelihood to deformation and a light hand feeling in the slat-turning operation. Meanwhile, heavier slats can be turned so that a larger area of louver can be manufactured, whereby a limitation of area of the prior-art louver is broken through and hollow glass doors and windows can be further spread and used in more broad fields.
