[0002] In the field of building doors and windows, window sashes are very common. Their core function is to meet the needs of natural lighting and ventilation inside the building, while taking into account the overall appearance of the building and the aesthetics of the spatial design. However, the installation height of some window sashes far exceeds the normal operating range of the human body, resulting in extremely poor convenience of opening, closing and angle adjustment.

[0003] The crank handle in the traditional combination bracket used for adjusting window sashes protrudes a certain distance and is installed at a low position for easy operation. It is easy to bump into people or objects during daily activities, posing a safety hazard. At the same time, the angle limit of the window sash relies on friction damping, which is prone to wear and loosening after long-term use, resulting in the window sash angle not being fixed firmly and possible accidental displacement. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-8 This utility model provides a technical solution: a combined bracket for adjusting window sashes, including a window sash adjustment component 3 installed on a window frame 1. Several window sashes 2 are installed inside the window frame 1. A linkage box 4 is fixedly connected to one side of the front part of the window frame 1 and below the window sash adjustment component 3. A rotating shaft 5 is rotatably connected to the top of the linkage box 4 through an opening. A limiting toothed ring 6 is fixedly connected to the surface of the rotating shaft 5 and inside the linkage box 4. Slide plates 7 are fixedly connected to both sides of the inner cavity of the linkage box 4. A slider 8 is slidably connected inside the slide plate 7. A movable frame 9 is fixedly connected to one end of the two sliders 8 facing each other. An arc-shaped toothed plate 10 that cooperates with the rotating shaft 5 is fixedly connected to the rear side of the movable frame 9.

[0025] It should be noted that if the limiting tooth ring 6 and the arc-shaped tooth plate 10 are not precisely engaged, the rotating shaft 5 can be slightly rotated so that the arc-shaped tooth plate 10 can engage with the limiting tooth ring 6.

[0026] Furthermore, to avoid the risk of bumps caused by the protruding handle 14, a first bevel gear 11 is fixedly connected to the bottom end of the rotating shaft 5. The front side of the linkage box 4 is rotatably connected to the handle docking cylinder 12 through an opening. The rear side of the handle docking cylinder 12 is fixedly connected to a second bevel gear 13 that meshes with the first bevel gear 11. The handle 14 is placed inside the handle docking cylinder 12. A protrusion 15 is fixedly connected to the surface of the handle 14. A slot 16 that matches the protrusion 15 is opened inside the handle docking cylinder 12.

[0027] Furthermore, in order to facilitate the automatic reset of the arc-shaped toothed plate 10 and the limiting toothed ring 6, the rotating shaft 5 is limited. A slide rod 17 is fixedly connected to the front side of the moving frame 9, and a spring 18 is fixedly connected between the slide rod 17 and the inner wall of the linkage box 4.

[0028] Furthermore, to ensure that the crank handle 14 releases the limiting position of the rotating shaft 5 simultaneously when it is inserted, and automatically locks itself after being pulled out, a pressing block 19 is slidably connected inside the crank handle docking cylinder 12. Push rods 20 are fixedly connected to both sides of the pressing block 19. Grooves for cooperating with the push rods 20 are provided on both sides of the crank handle docking cylinder 12. A contact ring plate 21 is fixedly connected to the opposite ends of the two push rods 20. A U-shaped plate 22 for cooperating with the contact ring plate 21 is fixedly connected to the surface of the sliding rod 17. Part of the contact ring plate 21 is partially embedded in the U-shaped groove of the U-shaped plate 22 (e.g., ...). Figure 3 As shown, through the contact force between the groove wall of the U-shaped plate 22 and the embedded part of the contact ring plate 21, the contact ring plate 21 can drive the U-shaped plate 22 to move synchronously. The groove wall of the U-shaped plate 22 is smooth, and the friction between the contact ring plate 21 and the U-shaped plate 22 can be ignored. When the contact ring plate 21 is embedded in the U-shaped groove of the U-shaped plate 22, the contact ring plate 21 can rotate freely around its own central axis, and the position of the U-shaped plate 22 is not affected during the rotation.

[0029] The window sash adjustment assembly 3 includes a transmission box 301, which is fixedly connected to one side of the front of the window frame 1. A transmission rod 302 is rotatably connected to one side of the transmission box 301 through an opening. A stabilizing plate 303 is rotatably connected to the end of the transmission rod 302 through a rotating component. The stabilizing plate 303 is fixedly connected to the other side of the front of the window frame 1. Several first connecting rods 304 are fixedly connected to the surface of the transmission rod 302. A second connecting rod 305 is rotatably connected to the end of the first connecting rod 304 through a rotating component. The end of the second connecting rod 305 is rotatably connected to the window sash 2 through a rotating component.

[0030] A third bevel gear 306 is fixedly connected to one end of the transmission rod 302 and inside the transmission box 301. One end of the rotating shaft 5 passes through the transmission box 301 and extends into the interior of the transmission box 301. A fourth bevel gear 307 that meshes with the third bevel gear 306 is fixedly connected to the end of the rotating shaft 5 that extends into the transmission box 301.

[0031] When in use, the operator holds the crank handle 14 and aligns it with the opening of the crank handle docking cylinder 12, ensuring that the protrusion 15 on the surface of the crank handle 14 is aligned with the slot 16 inside the crank handle docking cylinder 12.

[0032] The crank handle 14 is inserted into the crank handle docking cylinder 12. During the insertion process, the crank handle 14 abuts against and presses the pressing block 19, causing the pressing block 19 to move. The pressing block 19 drives the contact ring plate 21 to move synchronously through the push rod 20. The contact ring plate 21 abuts against the U-shaped plate 22 and pushes it to move. The U-shaped plate 22 drives the slide rod 17 to move, while stretching the spring 18. The slide rod 17 drives the arc-shaped toothed plate 10 away from the limiting toothed ring 6 on the surface of the rotating shaft 5 through the moving frame 9, releasing the rotation limit on the rotating shaft 5.

[0033] By turning the crank handle 14, the crank handle docking cylinder 12 is rotated, which in turn drives the second bevel gear 13 to rotate. The second bevel gear 13 meshes with the first bevel gear 11 and drives the first bevel gear 11 to rotate. The first bevel gear 11 drives the rotating shaft 5 to rotate synchronously. The rotating shaft 5 drives the fourth bevel gear 307 at its end to rotate. The fourth bevel gear 307 meshes with the third bevel gear 306 and drives the third bevel gear 306 to rotate, which in turn drives the transmission rod 302 to rotate. The transmission rod 302, through the linkage of the first connecting rod 304 and the second connecting rod 305, pushes the window sash 2 to open to the required angle.

[0034] After the angle of window sash 2 is determined, pull out the crank handle 14 and put it away. Under the elastic force of the spring 18, the slide rod 17 drives the moving frame 9 to move in the opposite direction. The arc-shaped toothed plate 10 on the rear side of the moving frame 9 engages with the limiting toothed ring 6 on the surface of the rotating shaft 5, completing the fixed limiting of the rotating shaft 5, and the window sash 2 maintains the current angle.
