Abstract

The invention provides a counter weight type invisible screen window. The barrel surface of the left end of a storage barrel is provided with a longitudinal through groove. A longitudinal limiting strip is arranged on the barrel surface of the front end of the storage barrel. A heavy object is connected with the limiting strip of the storage barrel through a limiting groove. An upper journal and a lower journal of a scroll are in shaft connection with the upper and lower barrel surfaces of the storage barrel correspondingly. An upper scroll head of the scroll extends out of the upper barrel surface and then is connected with a driven gear. One end of a screen curtain is connected with the scroll. The other end of the screen curtain penetrates out of the through groove to be connected with a connecting plate. A driving shaft is in shaft connection with left and right end faces of a driving box through a left shaft head and a right shaft head correspondingly. Reels and a driving gear are connected to the driving shaft. The driving box is connected to the upper portion of the storage barrel. The driving gear in the driving box is engaged with the driven gear on the storage barrel. Pull cords on the reels are wound around pulleys on the front end face of the driving box to be connected with the heavy object. When the screen window is closed, the heave object can drive the driving shaft to rotate through the pull cords and the reels. The driving shaft drives the scroll to rotate through the driving gear and the driven gear, and then the screen curtain is stored into the storage barrel.

Description

technical field [0001] The invention relates to an invisible screen window, in particular to a counterweight type invisible screen window which can drive a reel to rotate through a weight to recover and hide the screen curtain. Background technique [0002] At present, the known rolling-type invisible screen window is driven by a torsion spring to rotate the reel, and thus recovers and hides the screen. However, the torsion spring will deform and fail after being stretched for a long time. After use, the sheer curtain is difficult to recover normally. Contents of the invention [0003] In order to overcome the deficiency that the torsion spring of the existing roller blind type invisible screen window will be deformed and invalid after being stretched for a long time, the present invention provides a counterweight invisible screen window, which can drive the screen window through a weight The reel spins, reclaiming and hiding the sheer curtain. [0004] The technical sol...
