Spherical hinge for self-adaptive force loading

The invention belongs to the technical field of cable drive mechanisms and force loading, and discloses a spherical hinge for self-adaptive force loading, which comprises a rope, a lifting ring nut, a steel ball, a fixed base, a connecting screw and an adjusting gasket, the fixing bases are of triangular block structures, an adjusting gasket is clamped between the two symmetrical and identical fixing bases, and the fixing bases are fixed to a loaded object after being fixedly connected through connecting screws. Ball sockets are formed in the two waist sides of the two fixed bases, ball grooves corresponding to the ball sockets are formed in the adjusting gaskets, and the ball sockets are used for installing steel balls; a threaded hole is formed in the steel ball and fixedly connected with the lifting ring nut through threads, and the rope winds around the lifting ring hole and then is knotted to complete connection. The spherical hinge is simple in structure and convenient to install, the ball socket can ac
