Abstract: The present utility model discloses a smart lock with a modified structure comprising: a lock body including an inner handle and an outer handle, a latch and a bolt, an electrical locking mechanism for interfering retraction of the bolt; the lock body further comprises a manual locking and controlling mechanism connected to the inner and outer handles and controlling opening and closing; the manual locking and controlling mechanism is provided with a rotation actuating piece linked to the inner and outer handles and a bolt moving piece controlling extension and retraction of the bolt, wherein the rotation actuating piece is linked to the bolt moving piece via a locking member to control the bolt for locking when the inner and outer handles are lifted, and the rotation actuating piece is linked to the bolt moving piece via an unlocking member to control the bolt for unlocking when the inner and outer handles are pressed.

Abstract: A method and device for winding venetian blinds or honeycomb blinds, one ends of said multi-strand lift cords are fixedly connected with the underbeam of the venetian blinds or honeycomb blinds, while the other ends pass through the slats of the venetian blinds or honeycomb blinds converge into a strand rope; and finally the strand rope is fixedly connected with a winding reel which is rotated to wind the rope to realize the action of winding. The winding method of “many cords in one” is used in the present invention. The purpose of controlling the whole set of venetian blinds or honeycomb blinds is achieved by controlling a rope with a winding reel. The venetian blinds or honeycomb blinds of the present invention with simpler structure, more convenient installation, longer operating life, better lifting balance of the blinds, more beautiful products, and less influences of the window size.
