Description

A heavy-duty sliding brace hinge with anti-fall, anti-fall and dust-proof

technical field

The utility model belongs to the technical field of sliding brace hinges, in particular to a sliding brace hinge that is easy to install without a chute.

Background technique

The sliding brace hinge for casement windows is assembled by sliding rails, sliding blocks, guiding top angles and several supporting cantilevers: the sliding rails are open-shaped grooves formed by bending stainless steel sheets, and the sliding blocks are assembled in the openings. In the groove below the upper folded edge of the groove, the short bracket cantilever and one end of the bracket cantilever are hinged at the corresponding position of the slider; One end is hinged, the other end of the long support cantilever is hinged with the middle of the top support cantilever, and the head of the top support cantilever is hinged with the other end of the short support cantilever to form a link motion mechanism. The other end of the slide rail is provided with a guiding apex, which guides the opening and closing of the hinge. The sliding rail of the sliding support hinge and the corresponding position of the top support cantilever are provided with installation holes. During installation, the slide rail and the top support cantilever are respectively connected and fixed with the window frame and the window sash. When the window sash is pushed, the window sash passes through the top bracket installed on the window sash. The cantilever transmits the force to the link motion mechanism, and since the slider can slide in the slide rail, the motion mechanism moves under the force to open and close the window sash.

The weight of the window sash is supported by the top support cantilever on the short support cantilever and the long support cantilever, because the short support cantilever is stressed alone, while the long support cantilever is combined with the support cantilever (because the middle of the long support cantilever and the support cantilever. One end is hinged), so the force of the short bracket cantilever is larger than that of the bracket cantilever and the long bracket cantilever. While the slider bears the pressure of the short support cantilever and the support cantilever, it also needs to slide back and forth, and the stress situation is even worse.

The commonly used sliding brace hinges have the following disadvantages: 1. During the opening and closing process of the window sash, the bending or twisting of the sliding rail or the top support cantilever is caused by the change of force, so that the mounting screws are gradually loosened, and the window is used for a period of time. Afterwards, if it is not regularly cared for, especially if it is accidentally impacted by external force, the window sash will fall due to the loosening or failure of the screw, which will cause the window sash to detach from the top support cantilever or the sliding rail from the window frame. 2. After long-term use, the sliding block will deteriorate due to the long-term wear and tear, and the sash will be deformed or broken under the impact of external force, and it will be separated from the sliding rail, resulting in the inability to open and close the sash, and even the sash may occur. fall hazard. 3. For the sliding support hinge installed at the bottom end of the window sash, the short bracket cantilever is severely bent due to the large force, so that the head of the top bracket cantilever hinged with the short bracket cantilever is involved and bent down, resulting in the sash (and the top bracket). One end of the cantilever connection) hangs down. The sagging of one end of the sash makes the gap between the top of the sash and the window frame pull down and expand, which not only causes the window to not close tightly, but even causes the head of the top support cantilever of the sliding hinge connected to the top of the sash to be pulled down by the sagging sash and out of the guide. below the top corner. The sliding brace hinge cannot be opened or closed, resulting in the sash not being able to be opened and closed. 4. After a period of accumulation of dust falling on the sliding rail, it will hinder the sliding of the sliding block, making the window sash not open and closed smoothly or even unable to open and close.

In view of this, the present invention is proposed.
