[0025] Please refer to Figures 1-4 As shown, a high-density fitting louver curtain provided in this embodiment includes a window frame 1, louvers 2 and a pressing mechanism. The louvers 2 and the pressing mechanism are arranged inside the window frame 1, and the pressing mechanism is used to flatten the louvers 2.

[0026] The pressing mechanism includes a pressing strip 3, a hinge 4, a torsion spring 5, a traction rope 7 and a slider assembly 6. The pressing strip 3 is arranged on one side of the louvers 2. The pressing strip 3 is connected to the window frame 1 through the hinge 4 so that the pressing strip 3 can flip around the window frame 1 towards the louvers 2. The torsion spring 5 is sleeved on the rotating shaft 9 of the hinge 4, and the end of the torsion spring 5 extending outwards abuts against the inner side of the hinge 4 to prevent the hinge 4 from flipping towards the louvers 2. One end of the traction rope 7 is connected to the hinge 4, and the other end of the traction rope 7 is connected to the slider assembly 6. The slider assembly 6 is arranged inside the window frame 1 so that when the slider assembly 6 slides inside the window frame 1, it drives the traction rope 7 to flip the hinge 4 towards the louvers 2. A window glass is arranged inside the window frame 1. The slider assembly 6 includes a first slider, a second slider and a magnet. The first slider and the second slider are respectively located on both sides of the window glass, and the first slider and the second slider are connected by the magnet so that when the first slider slides, it drives the second slider to slide synchronously. The traction rope 7 is connected to the first slider. The number of the pressing mechanisms is two, and the two pressing mechanisms are respectively located on both sides of the louvers 2.

[0027] In the above embodiment, the present invention improves the existing louver window. When the existing louver window is lowered, due to the unique structure of the louver window, there are certain gaps between adjacent vanes. Through these gaps, people outside the window can peek into the situation inside the window, so to a certain extent, the privacy of users cannot be guaranteed. Therefore, the present invention installs pressing mechanisms on one side or both sides of the louvers 2 respectively, and presses the lowered louvers 2 flat on the window glass through the pressing mechanisms, so that the adjacent louvers 2 overlap, thereby eliminating the gaps between the louvers 2 and ensuring the privacy of users.

[0028] Specifically, as Figures 1-2 shown, it is the structural diagram of the louver window of the present invention.Figure 1 Internal structure diagram after the back of the shutter is opened (including shutter 2). Figure 2 It is also the internal structure diagram after the back of the shutter is opened (including shutter 2). The shutter includes a window frame 1, shutters 2 and window glass. The window frame 1 is rectangular, and the window glass is installed inside the window frame 1. The shutters 2 are also installed inside the window frame 1 to block the window glass. The pressing mechanism is installed on the side of the shutters 2. In a preferred solution, the pressing mechanism can be composed of a pressing strip 3, a hinge 4, a torsion spring 5, a traction rope 7 and a slider assembly 6. The pressing strip 3 can be a rectangular plastic pressing strip 3, which is connected to the side of the window frame 1 through the hinge 4, so that the pressing strip 3 can be turned inward around the side of the window frame 1 (i.e., turned towards the shutters 2), and the power to drive the turning of the pressing strip 3 is the traction rope 7.

[0029] By connecting the traction rope 7 to the movable side of the hinge 4 (i.e., the side where the pressing strip 3 is connected), pulling the traction rope 7 inward can press the pressing strip 3 against the shutters 2. In order to pull the pressing strip 3, the other end of the traction rope 7 is connected to the slider assembly 6. The slider assembly 6 is installed on the window glass, and the user can slide the slider assembly 6 on the window glass by hand, thereby realizing the pressing of the pressing strip 3. In this embodiment, the slider assembly 6 is composed of a first slider, a second slider and a magnet. The first slider and the second slider are respectively located on both sides of the window glass. The first slider is located inside the window glass, i.e., inside the window frame 1, and the second slider is located outside the window glass. The two are connected by a magnet to achieve synchronization, so that the user can realize the pressing of the shutters 2 through the second slider outside the window glass, thus ensuring the privacy of the shutter, as Figure 4 shown. At the same time, the torsion spring 5 is installed on the rotating shaft 9 of the hinge 4 and on the inner side of the hinge 4, and the end of the torsion spring 5 extending outward abuts against the movable side of the hinge 4, i.e., one side of the pressing strip 3. When the pressing of the pressing strip 3 is not required, the slider assembly 6 is driven in the reverse direction, and under the action of the torsion spring 5, the pressing strip 3 can quickly leave the shutters 2; at the same time, in this embodiment, in order to prevent the traction rope from being easily worn during the pulling process, conduction connectors can be provided at both ends of the window frame, i.e., near the hinges. The conduction connectors are provided with rollers, and the traction rope can be wound around the rollers to avoid direct contact with the sharp inner side of the window frame, thereby avoiding excessive wear of the traction rope.

[0030] In this embodiment, the pressing mechanism can be two groups or one group. The two groups of pressing mechanisms are respectively installed on both sides of the shutters 2, and driving the slider assembly 6 upward or downward can realize the pressing of the pressing strip 3.

[0031] In an alternative solution of the above embodiment, a window glass is provided inside the window frame 1, a slider assembly 6 is provided on the window glass, a retractable cord 8 is connected to the top of the louver 2, and the other end of the retractable cord 8 is connected to the slider assembly 6 through a first pulley, so that when the slider assembly 6 slides on the window glass, the retractable cord 8 is driven to retract and extend the louver 2.

[0032] The slider assembly 6 includes a first slider, a second slider and a magnet. The first slider and the second slider are respectively located on both sides of the window glass. The first slider and the second slider are connected by the magnet, so that when the first slider slides, the second slider is driven to slide synchronously. The retractable cord 8 is connected to the first slider.

[0033] In this alternative solution, a structure is provided to realize the retraction and extension of the louver 2. Specifically, as Figure 3 shown, this figure is the internal structure diagram (excluding the pressing mechanism) after the back of the louver window of the present invention is opened. The slider assembly 6 is connected to the top of the louver 2 through the retractable cord 8. One end of the retractable cord 8 is connected to the top of the louver 2. The other end of the retractable cord 8 passes through the inner side of the left part of the window frame 1 from the left and downwards, winds around the first pulley on the first slider of the slider assembly 6, and then passes through the limiting block on the left side of the window frame 1 and is limited. When the slider assembly 6 is driven downwards, the retractable cord 8 is pulled and retracted upwards. When the slider assembly 6 is driven upwards, the retractable cord 8 is released, and under the action of gravity, the louver 2 is released. In this alternative solution, as Figure 1 shown, the other end of the towing rope 7 connecting the hinge 4 should extend downwards, pass through the inside of the window frame 1 and be connected to the bottom of the first slider. In this way, the second slider can be driven upwards by hand, and the first slider moves synchronously to lower the louver 2. When the louver 2 reaches the limit, if it is necessary to completely close the louver 2, the second slider is driven upwards again to drive the towing rope 7 to pull the pressing strip 3 to press the louver 2. Therefore, a set of pressing mechanisms can be provided on the right side of the window frame 1 in the present invention to simultaneously realize the pressing of the louver 2 and the retraction and extension of the louver 2.

[0034] In an alternative solution of the above embodiment, a rotating shaft 9 is provided inside the window frame 1. The rotating shaft 9 is located at the top of the window frame 1. A sleeve is provided on the rotating shaft 9. A ladder belt pulling rope 11 is provided on the sleeve. The ladder belt pulling rope 11 is connected to the top of the louver 2. One end of the rotating shaft 9 is connected to a second pulley 10. A third pulley is provided below the second pulley 10. The second pulley 10 and the second pulley 10 are connected by a winding rope 12. A slider assembly 6 is provided on the winding rope 12. The slider assembly 6 slides inside the window frame 1 to pull the winding rope 12 to make the second pulley 10 rotate;

[0035] A window glass is provided inside the window frame 1. The slider assembly 6 includes a first slider, a second slider, and a magnet. The first slider and the second slider are respectively located on both sides of the window glass. The first slider and the second slider are connected by the magnet so that when the first slider slides, the second slider is driven to slide synchronously. The winding rope 12 is connected to the first slider.

[0036] In this alternative solution, a structure is provided, which can realize the angle adjustment of the louver 2. Specifically, as Figure 3 shown, this figure is the internal structure diagram (excluding the pressing mechanism) after the back of the louver window of the present invention is opened. By providing a rotating shaft 9 at the top of the window frame 1, a sleeve is provided on the rotating shaft 9. In this embodiment, two sleeves can be evenly arranged. The ladder belt pulling rope 11 is wound around the sleeve. The end of the ladder belt pulling rope 11 is connected to the top of the louver 2. The right end of the rotating shaft 9 is connected to the second pulley 10. The second pulley 10 is fixed to the right corner of the window frame 1 through a mounting seat. A third pulley is provided inside the window frame 1 below the second pulley 10. The third pulley and the second pulley 10 are connected by a winding rope 12. By connecting the slider assembly 6 to the winding rope 12, the winding rope 12 is driven by the slider assembly 6, thereby pulling the second pulley 10 and the second pulley 10 to rotate, and then driving the rotating shaft 9, the sleeve, and the ladder belt pulling rope 11 to realize the angle change of the blades, as Figure 1 shown, in this alternative solution, the other end of the traction rope 7 connecting the hinge should extend upward, wind back through the inside of the window frame 1 and be connected to the top of the first slider. In this way, the second slider can be driven downward by hand, and the first slider moves synchronously to adjust the angle of the louver 2. When it is necessary to completely close the louver 2, continue to drive the second slider downward, drive the traction rope 7 to pull the pressing strip 3 to press the louver 2. Therefore, the present invention can set a set of pressing mechanisms on the right side of the window frame 1 to simultaneously realize the pressing and angle change of the louver 2. During actual use, as Figure 3 is the state diagram of the louver 2 when the pressing mechanism is not used. At this time, the angle of the louver 2 can be freely adjusted by using the slider assembly 6 on the right side of the window frame 1. When it is necessary to completely seal the louver 2, it is necessary to continuously drive the slider assembly 6 downward, as Figure 2 shown is the state diagram of the louver 2 after sealing.

[0037] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
