Flexible cable connecting structure and bridge structure

A flexible cable connecting structure, comprising:

• a flexible cable;
• a first connecting portion connected to a top end of the flexible cable;
• and a second connecting portion connected to a bottom end of the flexible cable, wherein:
• the cable is rotatably connected to the first connecting portion and the second connecting portion, and is connected to at least one of the first connecting portion and the second connecting portion by using a spherical bearing pair;
• the first connecting portion comprises a hinge assembly rotating along one direction or a spherical hinge assembly rotating along multiple directions, and the second connecting portion comprises a spherical hinge assembly rotating along multiple directions;
• and
• the spherical hinge assembly comprises a spherical hinge cushion block and an anchoring beam, the anchoring beam is provided with a through hole, one end of the through hole comprises a taper hole, the other end of the through hole comprises a groove, the spherical hinge cushion block is provided with an arc-shaped protrusion matching a curvature diameter of the groove, an end part of the cable is inserted from the taper hole and is connected to the spherical hinge cushion block after passing through the through hole, and the protrusion is embedded into the groove to form the spherical bearing pair.
