Wind-resistant high-bearing door and window sliding support hinge

Abstract

The invention relates to the technical field of door and window hinges, and particularly relates to a wind-resistant high-bearing door and window sliding support hinge. The wind-resistant high-bearing door and window sliding support hinge comprises a window frame mounting plate, a window sash mounting plate, a first connecting rod, a second connecting rod and a third connecting rod, wherein the window frame mounting plate is provided with a limiting sliding groove, a limiting sliding block is arranged in the limiting sliding groove in a sliding mode, the first connecting rod is riveted to the window frame mounting plate and the third connecting rod, the second connecting rod is riveted to the first connecting rod and the window sash mounting plate, the third connecting rod is fixedly connected with a limiting block and riveted to the window sash mounting plate, the window sash mounting plate is provided with a limiting nail, the limiting nail is arranged at the lower end of the riveting position of the third connecting rod and the window sash mounting plate, the limiting sliding block is provided with an adjusting screw, and the sliding speed of the limiting sliding block in the limiting sliding groove is set. The second connecting rod is connected with the first connecting rod and the window sash mounting plate, the longitudinal stress area is increased, the bearing capacity is effectively improved, the anti-deformation capacity is improved, the maximum opening angle of the sliding support hinge is limited, the wind pressure resistance of the sliding support hinge is improved, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of door and window hinges, in particular to a wind-resistant and load-bearing sliding stay hinge for doors and windows. Background technique [0002] Door and window hinges are often used for auxiliary support connection between doors and windows and window frames to improve the safety of doors and windows when opening and closing. Most of the existing door and window hinges are installed with connecting rods superimposed on a riveting hole. For better fixing, it is necessary to Reduce the thickness of the connecting rod, which will reduce the load-bearing capacity of the door and window hinges. If the corresponding thickness of the connecting rod is maintained for the load-bearing capacity, the stability of the connecting rod will be reduced. The connecting rods are hinged with each other to form a hinge. Due to the lack of stoppers, the wind pressure resistance is relatively poor, and the window is likely ...

[0002] Door and window hinges are often used for auxiliary support connection between doors and windows and window frames to improve the safety of doors and windows when opening and closing. Most of the existing door and window hinges are installed with connecting rods superimposed on a riveting hole. For better fixing, it is necessary to Reduce the thickness of the connecting rod, which will reduce the load-bearing capacity of the door and window hinges. If the corresponding thickness of the connecting rod is maintained for the load-bearing capacity, the stability of the connecting rod will be reduced. Connecting rods, the connecting rods are hinged to each other to form a hinge. Due to the lack of stoppers, its ability to resist wind pressure is poor, and it is easy to cause the window to fall, so it is necessary to improve it
