Description

Novel hinge Technical Field The utility model relates to the technical field of window hinges, in particular to a novel hinge. Background Casement windows are a style of window in residential houses. The window sash is opened and closed along a certain horizontal direction, so that the window is called as a flat-open window. The hinge is installed at one side of the window sash and connected with the window frame, and is divided into an outer casement window and an inner casement window according to outward or inward opening. The window has the characteristics of simple structure, flexible opening and good sealing performance when being closed, and is the most wide window type adopted in civil buildings. The common flat-open window hinge in the existing market is poor in stability of the whole hinge due to the fact that the quantity of connecting rods is small, the weight of a window body is large, the connecting rods are easy to deform and fall down, vibration and even falling off are easy to occur in the using process, large wind pressure cannot be born, and when a plurality of hinges lack of locking structures capable of being automatically fastened by a frame fixing seat and a bracket arm when the window is closed by wind pressure, the wind pressure resistance is weak. Meanwhile, the existing casement window hinge is generally provided with a sliding groove or a sliding rail on the frame fixing seat, when the casement window hinge is used for a long time, dust or sundries are easily accumulated in the sliding groove or the sliding rail, sliding of the sliding block in the sliding groove or the sliding rail is affected, the service life of the hinge is further affected, and cleaning is difficult. The present utility model has been made based on the above circumstances. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the novel hinge which is simple in structure and flexible to open, a sliding structure is not required to be additionally arranged between the frame fixing seat and the linkage assembly, cleaning is more convenient, and when the hinge is closed to close a window, the bracket arm and the frame fixing seat can be automatically locked, so that the wind pressure resistance effect is good. The utility model is realized by the following technical scheme: the utility model provides a novel hinge, includes the frame fixing base and is used for installing the bracket arm of window board, still including rotate connect in first quarter butt on the frame fixing base, one end with first quarter butt is articulated and the other end is articulated with the near side frame end of bracket arm first stock, rotate connect in second quarter butt on the bracket arm, one end with second quarter butt is articulated and the other end is articulated with near side frame end of frame fixing base second quarter butt, the middle part of second quarter butt with the middle part of first quarter butt rotates to be connected.
