The specific structural features and the operation principle of the first spring plate 101a of the first curtain fabric 10a and the second spring plate 101b of the second curtain fabric 10b in the concealed window screen 1 according to embodiment 1 of the present invention will be described in detail below.

As shown in fig. 1 to 3, and in particular fig. 1, the hidden screen window 1 of embodiment 1 of the present invention further includes a first balance bar (not shown in the drawings), a second balance bar 16, a first spring plate 101a and a second spring plate 101b, and an elastic steel bar 101 disposed in the first spring plate 101a and the second spring plate 101 b.

As shown in fig. 1, the first balance bar is provided at the other end of the first curtain cloth 10a, and upper and lower ends of the first balance bar (not shown in the drawings) are respectively provided with a first spring plate 101a, and the second balance bar 16 is provided at the other end of the second curtain cloth 10b, and upper and lower ends of the second balance bar 16 are respectively provided with a second spring plate 101 b; wherein the first spring plate 101a exerts a first force on the first balance bar in a direction opposite to the first driving force, and wherein the second spring plate 101b exerts a second force on the second balance bar 16 in a direction opposite to the second driving force.

More specifically, a stretchable and elastic sheet-shaped steel bar is provided in the first and

second spring plates

101a and 101b, and fig. 1 shows only an extended state of the steel bar 101 in the second spring plate 101b for the convenience of understanding, and the steel bar 101 is shown in a dotted line. The length of the steel bars 101 in the first and second spring bars 101a and 101b is preferably greater than that of a window frame or a preset groove (not shown) in the hidden screen 1 so that a sufficient moving space can be provided to the first and second curtain cloths 10a and 10 b. One end of the first spring plate 101a is fixedly connected to the first drum 12a, the other end of the first spring plate 101a is a telescopic opening of a steel bar, and the steel bar is fixedly connected to a first balance bar (not shown in the drawings) which is used for moving horizontally in a track (not shown in the drawings) in the window frame or the predetermined groove at an even speed in a direction perpendicular to the window frame or the predetermined groove, so that the steel bars disposed at the upper end portion and the lower end portion of the first balance bar can uniformly and horizontally provide the first acting force to the first curtain cloth 10 a. Similarly, one end of the second spring plate 101b is fixedly connected to the second drum 12b, the other end of the second spring plate 101b is a telescopic opening of the steel bar 101, and the steel bar 101 is fixedly connected to the second balance bar 16, and the second balance bar 16 is configured to horizontally move in a rail (not shown) in the window frame or the pre-groove at an even speed in a direction perpendicular to the window frame or the pre-groove, so that the steel bars 101 disposed at the upper end and the lower end of the second balance bar 16 can uniformly and horizontally provide the second acting force to the second curtain cloth 10 b. The first driving force and the first acting force are balance forces, namely the first driving force and the first acting force are equal in size and opposite in direction. Similarly, the second driving force and the second acting force are mutually balanced, that is, the second driving force and the second acting force are equal in magnitude and opposite in direction. Furthermore, the interaction between the first driving force and the first acting force and the interaction between the second driving force and the second acting force enable the first curtain fabric 10a and the second curtain fabric 10b to be always in a tensioned and tight state during the winding and stretching processes of the first curtain fabric 10a and the second curtain fabric 10b relative to the first roller 12a and the second roller 12b, respectively, so that other irregularities such as bending or partial folding of the first curtain fabric 10a and the second curtain fabric 10b are avoided during the winding or stretching processes of the first curtain fabric 10a and the second curtain fabric 10b relative to the first roller 12a and the second roller 12b, respectively. Further, the flattened state of the first curtain cloth 10a and the second curtain cloth 10b also reduces the load force of the first driving device 11a, the second driving device 11b, the first roller 12a, and the second roller 12b, and accordingly, the service lives of the first driving device 11a, the second driving device 11b, the first roller 12a, and the second roller 12b are also prolonged.

The detailed structural features and the operation principle of the first shaft 121a and the second shaft 121b in the hidden screen window 1 according to embodiment 1 of the present invention will be described in detail below.

As shown in fig. 1, the two ends of the first shaft 121a of the first roller 12a in the horizontal direction and the two ends of the second shaft 121b of the second roller 12b in the horizontal direction are respectively provided with a fixed bearing 113, so that the first shaft 121a and the second shaft 121b are in a fixed state during the use of the hidden screen window 1, and can: such that said first drum 12a can only realize a rotation in a clockwise direction or in a counterclockwise direction around its first shaft 121 a; and such that said second drum 12b can only realize a rotation in a clockwise direction or in a counter-clockwise direction around its second shaft 121 b.
