Spherical hinge structure

The invention discloses a spherical hinge structure which comprises a ball seat, and a ball socket mounting cavity is formed in the ball seat. The ball socket is embedded in the ball socket mounting cavity; the end part of the ball pin is provided with a ball head, and the ball head is embedded into the ball socket along the axial direction of the ball pin; the lock cover is arranged at the opening of the ball socket mounting cavity, is fixedly connected with the ball seat and simultaneously presses the opening of the ball socket, so that the ball head is limited in the ball socket; a deformation section, a first conical section and a second conical section are sequentially arranged on the outer side wall of the ball socket in the direction from the opening end to the bottom of the ball socket, and the deformation section is deformed and folded when the lock cover is installed. The problems that an existing spherical hinge is low in load bearing upper limit and too large in torque during rotation can be solve
