It should be understood that the embodiments described herein are only used to explain the present application and do not limit the present application.

[0022] The utility model provides a many angle adjustable louver as shown in the figure Figures 1-7 The utility model provides a many angle adjustable louver as shown in the figure The utility model discloses a many angle adjustable louver, which comprises an outer frame 1 installed on a wall body, an inner frame 2 is rotatably connected in the outer frame 1, and an elastic limiting mechanism 3 matched with the inner frame 2 is arranged on the outer frame 1, the inner frame 2 is fixedly connected with a connecting rod 9 at the top and the bottom, and the connecting rod 9 is rotatably connected with the outer frame 1 through a bearing 10 at the end away from the inner frame 2, a cavity 4 is arranged in the frame on both sides of the inner frame 2, and a telescopic rod 5 is fixedly connected at the top in the cavity 4, a rack 6 is fixedly connected at the movable end of the telescopic rod 5, a plurality of S-shaped window leaves 7 are rotatably connected in the inner frame 2 from top to bottom, a gear 8 is fixedly connected at one end of the plurality of S-shaped window leaves 7 in the cavity 4, and the gear 8 is engaged with the rack 6, the rack 6 is moved by the telescopic rod 5 movable end telescopic, and then the gear 8 is rotated, and the opening and closing of the S-shaped window leaf 7 is realized.

[0023] As shown in the figure Figure 7As shown, the elastic limiting mechanism 3 in the utility model includes the recess 301 arranged on the side frame of the outer frame 1 and the movable plate 302 arranged in the recess 301 and connected with the outer frame 1 in sliding mode, the movable plate 302 is fixedly connected with the guide rod 303 penetrating through the side frame of the outer frame 1 and extending to the outside of the outer frame 1, one end of the guide rod 303 is fixedly connected with the pull ball 304, the side of the movable plate 302 away from the guide rod 303 is fixedly connected with the limiting block 305, the movable plate 302 and the side frame of the outer frame 1 are connected through the spring 306 sleeved on the outside of the guide rod 303, the side frame of the inner frame 2 is provided with the limiting hole matched with the limiting block 305, the top and bottom of the movable plate 302 are fixedly connected with the sliding block 307, the recess 301 of the outer frame 1 is provided with the sliding groove 308 for the sliding of the sliding block 307, the inner frame 2 can be cancelled from the limiting and fixing through the elastic limiting mechanism 3, so that the shutter can be completely opened, the ventilation performance and the aesthetic degree of the window are improved, meanwhile, the natural lighting and air circulation are facilitated.

[0024] Working principle: in the specific implementation of the utility model, the user can pull the pull ball 304, so that the guide rod 303 drives the movable plate 302 to move along the sliding groove 308 against the elastic force of the spring 306, at this time, the limiting block 305 is withdrawn from the limiting hole of the side frame of the inner frame 2, and the inner frame 2 loses the limiting and fixing of the outer frame 1 and can rotate freely. Through the rotating support structure formed by the connecting rod 9 and the bearing 10 between the inner frame 2 and the outer frame 1, the user can adjust the inner frame 2 to different angles according to the needs, realize the complete opening or partial opening state of the shutter, and improve the ventilation and lighting effect in the room.

[0025] When the user needs to close the shutter, only needs to rotate the inner frame 2 to the required position, releases the pull ball 304, the movable plate 302 is automatically reset under the elastic force of the spring 306, the limiting block 305 is reinserted into the limiting hole of the side frame of the inner frame 2, realizes the quick fixing between the inner frame 2 and the outer frame 1, this design not only guarantees the stability of the shutter when closing, but also facilitates quick adjustment, improves the convenience and comfort of use.

[0026] For the adjustment of the window leaf, when the inner frame 2 is in the fixed state, the user can control the movable end of the telescopic rod 5 to extend or retract, the movable end of the telescopic rod 5 pushes or pulls back the rack 6, since the rack 6 is engaged with the gear 8 at the end of the S-shaped window leaf 7, therefore, the movement of the rack 6 will cause the rotation of the gear 8, and further drive the S-shaped window leaf 7 to rotate around the connecting point of the gear 8 and the inner frame 2, realize the adjustment of the angle of the window leaf. At the same time, the design of the S-shaped window leaf 7 makes the window leaf flat when closing, which can effectively block the entry of dust from the outside and keep the room clean.
