Detailed Description
In order to more clearly and completely explain the technical scheme of the utility model, the utility model is further explained with reference to the attached drawings.
Referring to fig. 2, the present invention provides a fixed hinge for a casement window, including a sliding rail 1 fixed on a window frame, a first connecting portion 2 fixed on a window sash, a first sliding block 6 and a second sliding block 7 capable of sliding in the sliding rail 1; first connecting portion 2 through second connecting portion 3 swivelling joint in first sliding block 6, first connecting portion 2 through third connecting portion 4 swivelling joint in slide rail 1, third connecting portion 4 through fourth connecting portion 5 swivelling joint in second sliding block 7, just fourth connecting portion 5 with second connecting portion 3 swivelling joint, first connecting portion 2 is in first sliding block 6 with during the sliding of second sliding block 7 for slide rail 1 is angular motion.
In the present embodiment, the first connecting portion 2 is rotatably connected to the first slide block 6 by caulking via the second connecting portion 3, the first connecting portion 2 is rotatably connected to the slide rail 1 by caulking via the third connecting portion 4, the third connecting portion 4 is rotatably connected to the second slide block 7 by caulking via the fourth connecting portion 5, and the fourth connecting portion 5 and the second connecting portion 3 are rotatably connected by caulking.
In the present embodiment, the slide rail 1 is fixed to a side sash of a window, and is generally fixed by screws. The sliding rail 1 is provided with a sliding chute along the extending direction of the sliding rail 1; the first connection part 2 is fixed to the bottom of the sash of the window, typically also by screws. The first slider 6 and the second slider 7 are restricted in the direction perpendicular to the slide rail 1, so that the first slider 6 and the second slider 7 can only slide horizontally in the direction of extension of the slide rail 1.
Further, the fourth connection portion 5 is disposed to intersect with the second connection portion 3.
In the present embodiment, during the angular movement of the first connecting portion 2 relative to the slide rail 1 when the first slider 6 and the second slider 7 slide, the first connecting portion 2 and the fourth connecting portion 5 are always in a parallel relationship, and the second connecting portion 3 and the third connecting portion 4 are always in a parallel relationship. When the first connecting portion 2 is opened to the maximum angle relative to the slide rail 1, the load borne by the casement window hinge reaches the maximum, because the first connecting portion 2 and the fourth connecting portion 5 keep a parallel relationship, and the second connecting portion 3 and the third connecting portion 4 keep a parallel relationship, the self weight and the extra load of the window body connected by the first connecting portion 2 can be transmitted to the second connecting portion 3, the third connecting portion 45 and the fourth connecting portion 5, and further can be transmitted to the first sliding block 6, the second sliding block 7 and the slide rail 1, so that the bearing capacity of the casement window fixing hinge is improved.
In the embodiment, compared with the flat-open window hinge in the prior art that a single point transmits a load to the slide rail 1, the second sliding block 7 is arranged to bear the self weight and the extra load from the window body, so that multiple points are formed to transmit the load to the slide rail 1, on one hand, the bearing capacity of the fixed hinge of the flat-open window can be improved, on the other hand, the stress concentration of the slide rail 1 is avoided, and the service life of the slide rail 1 is prolonged.
Further, when the first connecting portion 2 makes an angular motion with respect to the slide rail 1, the first slider 6 and the second slider 7 slide in the same direction in the slide rail 1.
Further, the slide rail 1 has a first end 10 and a second end 11, and the first end 10 and the second end 11 are disposed opposite to each other.
Further, first connecting portion 2 for slide rail 1 is angular motion so that first connecting portion 2 with when contained angle between the slide rail 1 diminishes gradually, first sliding block 6 with second sliding block 7 all slides toward first end 10, just first sliding block 6 with distance between the second sliding block 7 grow gradually, work as first connecting portion 2 for slide rail 1 is closed, promptly first connecting portion 2 with when contained angle between the slide rail 1 is 0, first sliding block 6 with distance between the second sliding block 7 reaches the biggest.
Furthermore, first connecting portion 2 for slide rail 1 is the angular motion so that first connecting portion 2 with when the contained angle between the slide rail 1 becomes big gradually, first sliding block 6 with second sliding block 7 all slides towards second end 11, just first sliding block 6 with distance between the second sliding block 7 diminishes gradually. When the first connecting portion 2 is opened to the maximum angle, i.e. the maximum amplitude of the window, relative to the slide rail 1, the included angle between the first connecting portion 2 and the slide rail 1 reaches the maximum, and the distance between the first sliding block 6 and the second sliding block 7 reaches the minimum.
Further, the second connecting portion 3 and the first sliding block 6 are connected by a rivet 8 to realize a rotary connection.
Further, the rivet 8 is spaced apart from the second connecting portion 3 and the first slide block 6, and the rivet 8 is supported by the second connecting portion 3 and the first slide block 6 so that the second connecting portion 3 does not abut on the first slide block 6.
Furthermore, an avoiding notch 50 is formed in the fourth connecting portion 5, and when the first connecting portion 2 makes an angular motion relative to the slide rail 1 so that an included angle between the first connecting portion 2 and the slide rail 1 is 0, the rivet 8 is accommodated in the avoiding notch 50.
In this embodiment, when the first connecting portion 2 makes an angular motion relative to the slide rail 1 so that an included angle between the first connecting portion 2 and the slide rail 1 is 0, that is, when the window is closed, the rivet 8 is accommodated in the avoiding notch 50 and the rivet 8 abuts against the side wall of the avoiding notch 50, and the rivet 8 and the avoiding notch 50 are matched with each other, so that the first connecting portion 2 can be prevented from making an angular motion relative to the slide rail 1 in another direction, and a limiting effect is achieved.
Further, when the included angle between the first connecting portion 2 and the slide rail 1 is 0, the end surface of the first connecting portion 2 does not protrude from the end surface of the first end 10.
Of course, the present invention may have other embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative effort, and all of them are within the protection scope of the present invention.
