Hinge with adjustable sealing performance

The invention relates to a hinge with adjustable sealing performance. An adjusting concave cavity is formed in an adjusting column, so that a first shaft part of an eccentric adjusting shaft can be inserted into the adjusting concave cavity, and the horizontal position of a window sash is adjusted by rotating a second shaft part which is eccentrically arranged; an adjusting nut is arranged, so that the axial position of the window sash is adjusted, then the window sash is adjusted according to needs, and the sealing performance of a product is improved; and a limiting clamping plate is arranged, so that the hinge is prevented from shaking in a closed state. 本发明涉及一种可调节密封性的铰链，通过在调节柱上设置调节凹腔，使偏心调节轴的第一轴部能插入到调节凹腔内，通过转动偏心设置的第二轴部实现窗扇的水平位置调节，通过设置调节螺母，实现窗扇的轴向位置调节，进而对窗扇实现按需调节，提高产品密封性，通过设置限位卡板，避免铰链在闭合状态下晃动。
