[0007] As a preferred technical solution of the utility model, a plurality of rollers are axially connected in the two long grooves, and there are eight pairs of fastening protrusions in total, wherein the lengths of the two outermost pairs of fastening protrusions are greater than the lengths of the six middle pairs of fastening protrusions.

[0008] As a preferred technical solution of the utility model, the driving mechanism includes a screw, which is threadedly connected to the movable frame, and a first bevel gear is welded on the screw. The front side of the first bevel gear is meshingly connected to the second bevel gear, and the front center of the second bevel gear is integrally connected to a connecting shaft connected to the inner wall shaft of the front side of the cavity.

[0009] As a preferred technical solution of the utility model, a turning handle integrally connected to the front end of the connecting shaft is provided on the front side of the frame, and both ends of the screw are rotatably connected to the inner wall shafts on both sides of the cavity respectively.

[0010] As a preferred technical solution of the utility model, the foldable frameless window is hingedly connected by two windows, the upper and lower ends of the two windows are slidably and rotatably connected to the slide groove, and both sides of the window are frameless.

[0011] Compared with the prior art, the utility model provides a foldable frameless balcony window, which has the following beneficial effects: on the basis of the existing foldable frameless balcony window, long grooves and cavities are added to the frame, and with the customized driving mechanism, rack, moving frame, gear and fastening protrusions, when the balcony window is closed, all the fastening protrusions are in a vertical state, which can limit the foldable frameless window and improve the stability of the foldable frameless window after closing; when the balcony window is opened, the two foldable frameless windows are folded in half and moved to the inner walls on both sides of the frame, and the fastening protrusions are tilted downward. Since the length of the outermost two pairs of fastening protrusions is longer than the middle six pairs of fastening protrusions, only the outermost two pairs of fastening protrusions protrude and limit the foldable frameless window to stabilize it. In strong winds, it will not shake and has high safety. The middle fastening protrusions are still stored in the long grooves and are in a hidden state, and the aesthetics will not be affected.
