Description

High-bearing wind-resistant hinge Technical Field The utility model relates to the technical field of hinges, in particular to a high-bearing wind-resistant hinge. Background There are various types of windows in the market, such as a tilt-turn window, a sliding window and a flat-open window. The window in the existing market mainly comprises a window frame and a window sash, whether the window is safe and reliable or not is determined by connection between the window frame and the window sash, and in addition, the window sash connection effect influences various performances of the window. The current window frame and window sashes are generally connected by adopting a hinge, and the weight of the window sashes is required to be borne by the hinge and the window sashes are supported to rotate, so that the service life of the window and the door is greatly determined by the bearing performance of the hinge. The existing door and window hinge mostly overlaps the connecting rod in a riveting hole site fixed when setting up, and then needs reduce connecting rod thickness for better fixed, so can reduce door and window hinge's bearing capacity, if keep corresponding connecting rod thickness for bearing capacity then can reduce the stability of connecting rod. The Chinese patent grant publication number is CN 220645596U, which discloses a wind pressure resistant hinge, and the wind pressure resistant hinge mainly has the following defects: 1. One end of the first connecting rod is connected with the bottom plate in a hinging mode, the window sashes are fixed on the mounting plate, when the window sashes are installed, downward gravity is applied to the window sashes, the hinged ends of the first connecting rod can be tilted, and the hinged ends of the first connecting rod are only fixed through hinging, so that stress after the hinged ends of the first connecting rod are tilted can not be decomposed, after a long time, the window sashes are easily connected with each other, and the wind resistance performance is poor. 2. One end of the first connecting rod and the hinged end of the bottom plate are fixed at the same position to rotate, so that the distance between the hinged end and the jack is fixed, that is, the distance between one side of the window sash and the wall body is fixed, and a gap is formed only through a rotating mode, so that the back of the window sash and the position between the window sash and the wall body are too small, and the hand is inconvenient to extend into the wall body for cleaning. Disclosure of utility model In order to overcome the defects in the prior art, the utility model aims to provide the high-bearing wind-resistant hinge which can effectively improve the bearing capacity and wind resistance of the door and window hinge. The high-bearing wind-resistant hinge comprises a bottom plate and an opening and closing mechanism, wherein the opening and closing mechanism is provided with an opening and closing end and a connecting end, the opening and closing mechanism comprises a long arm, a middle arm, a supporting arm and a cantilever, a sliding groove is formed in one side of the bottom plate, sliding pieces which are arranged in a sliding mode are arranged in the sliding groove, the opposite ends of the long arm are respectively hinged with the bottom plate and the supporting arm, the opposite ends of the middle arm are respectively hinged with the sliding pieces and the supporting arm, the opposite ends of the cantilever are respectively hinged with the sliding pieces and the supporting arm, the sliding pieces drive the opening and closing end to form an opening state or a superposition state relative to the bottom plate when sliding along the sliding groove, and the hinging points among the long arm, the middle arm, the cantilever and the supporting arm are different. Preferably, a turnover plate is arranged on one side of the upper surface of the bottom plate, the sliding groove for the sliding piece to slide is formed between the turnover plate and the bottom plate, one end of the sliding groove is an opening, and the other end of the sliding groove is provided with a limiting structure. Preferably, the limiting structure is a limiting pin, and the limiting pin penetrates through the turning plate and is fastened on the bottom plate so that the sliding piece slides to the limiting position. Preferably, the sliding part comprises a sliding part main body arranged in the sliding groove in a sliding way, and a first wear-resisting piece formed on one side of the sliding part, wherein one end of the sliding part is provided with a second wear-resisting piece hinged with the sliding part, the first wear-resisting piece is provided with a supporting piece hinged with one end of the middle arm, and the cantilever is fixed on the second wear-resisting piece.
