TECHNICAL FIELD

[0001] The utility model relates to the technical field of door and window accessories, and particularly relates to a top and bottom rotating shaft hinge for doors and windows. BACKGROUND

[0002] The door and window top and bottom hinge is an important hardware accessory connecting the door and window fan and frame, which can realize stable rotation and positioning of the door and window fan when opening. The hinge is usually installed at the upper and lower ends of the door and window, and is mainly used in the occasions requiring rotation opening, such as doors and windows. Referring to the utility model patent with publication (announcement) number CN205908168U, the top and bottom hinge on the market comprises a fixed seat, a rotating shaft and a connecting piece. The connecting piece is rotatable on the fixed seat through the rotating shaft. The fixed seat is fixed on the frame through screws. The angle code connecting piece is fixed on the fan through screws. Such structure cannot be adjusted after being fixed. For example, slight deviation in the installation position of the upper and lower ends will cause the rotation point of the upper and lower hinges to deviate from the same center line, thereby affecting the normal use of the door and window. Once the installation deviates, the door and window needs to be removed and reinstalled. Therefore, the installation precision is required to be high, which leads to great inconvenience in installation. Moreover, the current top and bottom hinge lacks a buffering and positioning structure.
