The hinge anti-warping structure is installed on the hinge, the hinge comprises a first connecting rod and a bottom plate, one end of the first connecting rod is rotationally connected with the bottom plate through a spin riveting shaft, the hinge anti-warping structure comprises an anti-warping piece, the spin riveting shaft sequentially penetrates through the first connecting rod and the bottom plate and is connected with one end of the anti-warping piece, and the other end of the anti-warping piece is connected with the bottom plate. An anti-warping part is arranged on the anti-warping piece, and when the hinge is installed on a window frame, the anti-warping part abuts against a profile installation groove of the window frame. According to the hinge, the first connecting rod and the anti-warping piece are connected through the spin riveting shaft, the anti-warping piece abuts against the window frame, and the gravity action of a window sash borne by the first connecting rod can be transmitted to the window frame, so that the bottom plate of the hinge does not warp or deform, inclination and sagging of the window sash are avoided, the window sash can be normally closed, and the service life of the window sash is prolonged. The anti-warping effect of the hinge and the user experience are improved, the bearing performance and safety of a window sash are improved, and meanwhile the hinge cost is reduced.
