Fig. 3 is a side view structural schematic diagram of the window sash fixing frame of the present invention.

Among the figure: outer frame fixing frame 1, sash fixing frame 2, first connecting rod 3, second connecting rod 4, third connecting rod 5, through groove 10, slide block 11, base plate 21, supporting plate 22, connecting plate 23, abutting column 211.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in the accompanying drawings, a wind-resistant hinge of the utility model includes an outer frame fixing frame 1, a sash fixing frame 2, a first connecting rod 3, a second connecting rod 4 and a third connecting rod 5. The abutting column 211 of the third link 5 opens the sash, and the sash fixing frame 2 is opened accordingly, as shown in Fig. 1 or Fig. 2 , the figure shows that the sash fixing frame 2 is opened until the first connecting rod 3 abuts against one end of the bottom plate 21.

The principle and effect of a wind-resistant hinge of the utility model is that the bottom plate 21 arranged at the bottom of the sash fixing frame 2 resists the rotation angle of the first connecting rod 3, and at the same time, the abutting column 211 arranged under the bottom plate 21 is used to resist the rotation angle of the third connecting rod 5. When it is opened to the maximum angle state, the bottom plate 21 is tightly pressed against the first connecting rod 3, and at the same time, the abutting column 211 under the bottom plate 21 is tightly pressed against the third connecting rod 5, so that the first connecting rod 3 and the third connecting rod 5 cannot continue to rotate, thereby limiting The maximum opening angle of the sash fixing frame 2 is controlled, thereby improving the wind resistance performance of the hinge, preventing the sash or the hinge from being affected by wind force, and reducing the risk of the sash falling.

In this embodiment, the first connecting rod 3 and the third connecting rod 5 are both rotatably connected to the outer frame fixing frame 1, and the other ends are rotatably connected to the sash fixing frame 2. One end of the second connecting rod 4 is movably connected to the outer frame fixing frame 1, and the other end is rotatably connected to the first connecting rod 3. The outer frame fixing frame 1 is provided with a through groove 10, and a slider 11 is slidably connected in the through groove 10. The second connecting rod 4 is rotatably connected to the slider 11. The first connecting rod 3, the second connecting rod 4 and the third connecting rod 5 are arranged outside. on the frame fixing frame 1, and are respectively connected to the window sash fixing frame 2 and the outer frame fixing frame 1 through connecting pieces such as rivets. The slider 11 is made of plastic, and one end of the second connecting rod 4 is rotatably connected to the slider 11 , and is slidably connected to the through groove 10 through the slider 11 .

In this embodiment, the sash fixing frame 2 includes a connecting plate 23 and a supporting plate 22. The connecting plate 23 is arranged on the upper side of the supporting plate 22, the bottom plate 21 is arranged on one end of the lower side of the supporting plate 22, and the first connecting rod 3 is arranged on the other end. As a function, the third connecting rod 5 is arranged on the lower side of the bottom plate 21, and the third connecting rod 5 and the abutment column 211 are respectively arranged at both ends of the lower side of the bottom plate 21. When the sash fixing frame 2 is opened to a certain angle, the abutting column 211 is tightly pressed against the third connecting rod 5, so that the sash fixing frame 2 cannot continue to open, and at this time it is the maximum opening angle.

The above-mentioned embodiments are preferred embodiments of the present utility model, and all structures similar to the present utility model and the equivalent changes made should belong to the protection category of the present utility model.
