Technical field

The utility model relates to a window stay, in particular to a sliding hinge joint for a safety type flat window. Background technique

The sliding hinge commonly used for casement windows is a movement mechanism assembled by a slide rail, a slider and a plurality of hinged suspension arms. One end of the slide rail is provided with a guiding and guiding apex angle for opening and closing of the hinge; and a screw hole for mounting is provided at a corresponding position of the top bracket cantilever and the sliding rail, and a pair of sliding hinge hinge rails are installed during installation. They are respectively fixed by screws on the upper and lower ends of the window frame, and the top support cantilever of the sliding hinge is respectively fixed and fixed on the upper and lower ends of the window sash. When the sash is pushed, the sash transmits the force to the moving mechanism through the cantilever mounted on the top of the sash. Since the slider can slide in the slide rail, the motion mechanism moves under the force to open and close the sash. If the window is used after a period of time, if it is not regularly treated, or if it is accidentally subjected to an external force, the window sash may fall due to looseness or failure of the screw. In order to solve the above problems, a C-shaped groove is generally added to the profile of the window frame and the sash, so that the top support cantilever and the slide rail of the sliding hinge are respectively embedded in the C-shaped groove of the sash and the window frame, thereby effectively protecting the window. In the case of accidental external impact, there is a danger of window sag falling due to screwing or failure. However, there is still a hidden danger that may cause the window sash to fall: When the sash is accidentally impacted by external force (especially if the sliding stay is used for a long time and the slider is worn), the slider will be deformed due to insufficient bearing capacity. Or break, get out of the rails, causing the window sash to fall. SUMMARY OF THE INVENTION The technical problem to be solved by the embodiments of the present invention is to provide a sliding hinge for a swing window, which can prevent the sash from falling by an external force, and includes a slide rail, a slider and a suspension arm assembly, wherein The slider is an elongated metal slider having a "U" shaped notch at the front end thereof; the support cantilever assembly includes the first The cantilever arm, the second supporting cantilever, the third supporting cantilever and the top supporting cantilever are formed by connecting the first-stage top cantilever and the secondary top supporting cantilever which are curved into a step shape at a curved portion.

The primary top support cantilever and the secondary top support cantilever are provided with notches on both sides of the joint. Preferably, the primary top support cantilever is embedded in the sash C-shaped groove, and the secondary top support cantilever is located outside the sash C-shaped groove and is respectively hinged with the first support arm and the third support arm. The notch is used to jump over the slot of the sash C-slot. The structure of the top bracket can be securely embedded in the C-shaped slot of the sash to prevent the sash from falling, and the hinge of the top bracket and other brackets is not affected.

It should be noted that the curved joint of the top support cantilever is made by a stamping process.

The edge of the slider is inserted below the edge of the rail so that the slider can slide within the rail without disengaging the rail.

The middle portion of the slider is provided with an upwardly protruding screw hole, and the screw hole is provided with an adjusting screw.

The protrusions provided by the screw holes are used to increase the length of the thread to prevent failure.

An adjusting screw is disposed in the screw hole, and a lower surface of the screw hole is equipped with a friction pad, and a side of the friction pad contacting the sliding rail and a corresponding surface thereof are arc-shaped, and are assembled before the sliding rail a curved surface contacting the slide rail protrudes from a bottom surface of the slider, is assembled into the slide rail and is compressed in the slider, so that there is pressure between the friction washer and the slide rail Conducive to increasing the frictional force to resist the wind force. At the same time, a slope with a slope at the bottom of the sliding rail near the guiding apex angle can further increase the resistance of the closing sash and prevent opening at a certain position. The sash suddenly closed and was damaged. When the friction force is reduced or insufficient, the friction washer can be pushed to press the slide rail by rotating the adjusting screw in the screw hole to increase the friction.

Preferably, the sliding hinge of the utility model adopts an elongated copper slider, and the top surface of the front end of the hinged end of the first supporting bracket has a U-shaped notch to avoid blocking by the screw head. The slider It cannot be closed. The elongated slider can increase the contact force surface between the support cantilever, especially the first suspension arm and the slider, so that the support can bear a heavier sash without sagging, more important The purpose of the invention is to increase the contact force surface between the edge of the slider and the edge of the sliding rail, thereby improving the bearing capacity and wear resistance of the slider, and ensuring that the slider is not subjected to additional force or cause. Worn out of the rail. The implementation of the embodiment of the present invention has the following beneficial effects:

By implementing the utility model, the falling of the window sash can be effectively prevented, and the hinge of the top supporting cantilever and the other supporting cantilever is not affected, the bearing capacity and wear resistance of the sliding block are improved, and the wear of the sliding block and the additional force deformation are avoided. It causes the sash to fall, and also has enough friction, so that the sash will not be closed and damaged by the wind, which greatly improves the safety of the sash.
