Abstract

The invention discloses a telescopic screen window. A plurality of roll shafts are arranged in a storage box in parallel; a plurality of convex ribs are arranged below a box cover; each rib corresponds to a middle dividing line among all the roll shafts; a left connecting rod and a right connecting rod are crossed and are connected through a rotating shaft; a plurality of balance weight levers are arranged below each rib in parallel; the upper and lower ends of each of the left connecting rod and the right connecting rod are respectively connected with the ribs and the balance weight levers; the screen window frame is connected to the downside of the storage box; and a driving plate is horizontally arranged in the screen window frame. A gauze curtain bypasses each roll shaft and each balance weight lever respectively from top and bottom in a staggered way; and one end of the gauze screen is connected with the roll shaft at the final end in the storage box, and the other end of the gauze screen is connected with the driving plate in the screen window frame after penetrating out of the storage box. When the gauze screen is dragged downwards by the driving plate, the gauze screen can drive the connecting rods and the balance weight levers in the storage box to upwards shrink. When the driving plate upwards moves, each balance weight lever in the storage box can be matched with each roll shaft to carry out foldaway recovery on the gauze screen under the action of gravity.

Description

technical field [0001] The invention relates to an invisible screen window, in particular to a retractable screen window which can recover the screen curtain by gravity. Background technique [0002] At present, the known invisible screen window is a rolling shutter structure, which uses elastic force to recover the screen curtain. Since the driving spring in the reel will be damaged due to long-term stretching, the existing rolling blind type invisible screen window will be damaged after being used for a period of time. Its gauze curtain just cannot be recovered normally. Contents of the invention [0003] In order to overcome the shortcoming that the drive spring in the reel of the existing invisible screen window is easily damaged, the present invention provides a telescopic screen window, which can use gravity to fold and recover the screen curtain, thus avoiding the damage caused by the drive spring. The entire screen window cannot be used normally due to damage. ...
