The invention provides a combined type optical fiber ring skeleton for an optical fiber gyroscope. The combined type optical fiber ring skeleton is provided with an inner optical fiber ring skeleton, an outer optical fiber ring skeleton and a mounting plate, wherein the inner optical fiber ring skeleton and the outer optical fiber ring skeleton are respectively of an H-shaped ring structure; the lower end surface of the inner optical fiber ring skeleton is fixedly arranged on the mounting plate; an optical fiber winding ring surface I and an optical fiber winding ring surface II are respectively provided with optical fibers, the optical fibers are symmetrically arranged in a quadrupole way, and adhesive coating discs at the two optical fiber outlet ends are arranged on an optical fiber disc mounting surface I and an optical fiber disc mounting surface II; the inner optical fiber ring skeleton is embedded into a center hole of the outer optical fiber ring skeleton, and the lower end of the outer optical fiber ring skeleton is fixedly arranged on the mounting plate. The combined type optical fiber ring skeleton has the advantages that the high-precision optical fiber winding length is shared onto the inner optical fiber ring skeleton and the outer optical fiber ring skeleton, the number of winding turns is reduced, the winding difficulty of operators is decreased, and the qualified rate is improved; by adopting the quadrupole symmetric optical fiber winding way, the influence to the property of the optical fiber gyroscope by temperature gradient effect is effectively reduced, and the vibration property of the optical fiber gyroscope is improved; the structure is simple, and the operation is easy.
