Abstract: Disclosed is a sliding door or window. The sliding door or window includes a door/window frame, a swing fastening mechanism is disposed at a lower end of a side of the door/window frame, and a locking structure is mounted on an upper end of the side of the door/window frame. The swing fastening mechanism and the locking structure are each provided with a snakelike groove inside which a shaft operative to slide along a groove orientation is arranged. A handle disposed on the door/window frame is operative to drive the shaft to slide in the snakelike groove, thereby forcing the swing fastening mechanism or/and the locking structure to swing.

Abstract: A frame structure includes a frame body, a corner connector and roller mechanism arranged in a splice of adjacent side frames at a bottom of the frame body, and a guide mechanism clamped to a top of the frame body. A glass positioning slot is disposed on a first side of an inner side wall of a side frame of the frame body. A mounting slot is disposed on a first side of an outer side wall of the side frame of the frame body and used for fixing the guide mechanism or the corner connector and roller mechanism. The glass positioning slot is adjacent to the mounting slot along a lengthwise direction of the first side of the inner side wall. A sliding door is further provided.

Abstract: A door-and-window system having a handle component (121), a transmission component (123) and a force receiving portion (12231). When the handle component (121) is operated, the force receiving portion (12231) moves along a first guide groove (12211) via the transmission component (123), and at the same time a driving portion (12232) moves along a second guide groove (12221). Due to a relationship between a guide member (1224) and a third guide groove (12212), a first base seat (1221) translates relative to a second base seat (1222) along a direction of the third guide groove (12212), such that a movable door-and-window (11) can abut tightly against or move away from a sealing member (24) on a door-and-window mounting profile (2).

Abstract: Disclosed is a door-and-window system, in which a handle component (121) is assembled via a transmission component (123) with a force receiving portion (12231) of a movable door-and-window assembly component (122). When the handle component (121) is operated, the force receiving portion (12231) moves along a first guide groove (12211) thanks to the force transmission effect of the transmission component (123), and at the same time a driving portion (12232) moves along a second guide groove (12221). Due to an assembly relationship between a guide member (1224) and a third guide groove (12212), a first base seat (1221) translates relative to a second base seat (1222) along a direction of the third guide groove (12212), such that a movable door-and-window (11) can abut tightly against or move away from a sealing member (24) on a door-and-window mounting profile (2).
