[0002] With the continuous development of urban construction, more and more buildings are using glass curtain walls. Most existing glass curtain walls use aluminum alloy profiles for the window frames and sashes. The window sashes can be opened and closed in two ways: casement and outward opening. Casement window sashes are usually connected by hinges. Most existing hinges are multi-link hinges, which enable the window to open and close smoothly through multiple links. For hinges with a full rotation point structure, the operating force for opening and closing the window needs to be carefully controlled during the riveting of the pivot.

[0003] In the prior art, such as Chinese Patent CN 211258187 U, a friction hinge for a door and window includes a mounting plate; a first support arm, one end of which is hinged to the mounting plate and the other end to a window sash mounting arm; a second support arm, one end of which is hinged to the window sash mounting arm and the other end to the mounting plate; and a limiting block disposed on the window sash mounting arm, the first support arm, or the second support arm. When the angle between the window sash mounting arm and the mounting plate is equal to a preset angle, the limiting block abuts against the first support arm, the second support arm, or the window sash mounting arm. This utility model's friction hinge for windows, by providing a limiting block on the window sash mounting arm, the first support arm, or the second support arm of the friction hinge, provides support for the window sash mounting arm, the first support arm, or the second support arm in strong wind environments when the angle between the window sash mounting arm and the mounting plate is equal to a preset angle. However, this patent still has the following problems.

[0004] In the aforementioned patent, although the limiting block is set to support the window sash mounting arm, the first support arm, or the second support arm in a strong wind environment, when the hinge is in use, external dust may enter the slide groove, affecting the movement of the slider, and cleaning may be more difficult, thus increasing the cleaning burden on the user.

[0030] The effect achieved by the entire embodiment 1 is as follows: when the moving block 301 moves, the slider 302 moves within the slide rail 7. The slider 302 pushes the dust inside the slide rail 7 to move. When the slider 302 contacts the inclined surface of the baffle 404, the baffle 404 rises and the first spring 402 is compressed. At this time, the dust can be pushed into the collection frame 405 by the slider 302. When the staff cleans, the collection frame 405 is taken out from the collection groove 8, the iron block 406 leaves the connecting groove 9, and finally the dust inside the collection frame 405 is removed. Finally, the iron block 406 is re-attracted to the magnet 10, thus completing the cleaning and improving the cleaning efficiency.

[0031] Example 2, as Figures 1-6As shown, the top of the movable block 301 is hinged to a first support arm 303, one end of the first support arm 303 is hinged to a second mounting bracket 6, the outer wall of the second mounting bracket 6 is hinged to a second support arm 304, one end of the second support arm 304 is hinged to the first mounting bracket 2, and a third support arm 305 is provided on the outside of the second support arm 304, with both ends of the third support arm 305 being hinged to the first mounting bracket 2 and the second mounting bracket 6 respectively.

[0032] Furthermore, the outer walls of the first mounting bracket 2 and the second mounting bracket 6 are provided with multiple fixing structures 5. The fixing structure 5 includes a plate 501.

During disassembly, the worker pulls the pull plate 505, which moves the locking block 506 away from the slot 103, thus removing the insert plate 501 from the slot 102, improving the efficiency of installation and disassembly.

[0038] Working principle: During installation, the operator inserts the insert plate 501 into the slot 102. The inclined surface of the locking block 506 contacts the inner wall of the slot 102, and the locking block 506 is squeezed into the opening 503. The second spring 504 is compressed. When the locking block 506 moves to the side of the slot 103, it enters the slot 103 under the elastic force of the second spring 504, thus completing the installation. During disassembly, the operator pulls the pull plate 505, which moves the locking block 506 away from the slot 103, thus removing the insert plate 501 from the slot 102, improving the efficiency of installation and disassembly. When the moving block 301 moves, the slider 302 moves within the slide rail 7. The slider 302 pushes the dust inside the slide rail 7 to move. When the slider 302 contacts the inclined surface of the baffle 404, the baffle 404 rises, and the first spring 402 is compressed. At this time, the dust can be pushed into the collection frame 405 by the slider 302. When the staff cleans, the collection frame 405 is removed from the collection groove 8, the iron block 406 leaves the connecting groove 9, and finally the dust inside the collection frame 405 is removed. Finally, the iron block 406 is re-attracted to the magnet 10, thus completing the cleaning and improving the cleaning efficiency.
