The invention belongs to the technical field of compressors, and particularly relates to a floating type axial sealing structure. The technical scheme is as follows the floating type axial sealing structure comprises a static scroll plate and a dynamic scroll plate are correspondingly provided with a vortex tooth, a sealing groove is formed in the tooth surface of the vortex tooth, and a sealing structure is arranged in the groove; the shape of the sealing structure corresponds to the shape of the vortex tooth, the sealing structure is composed of a wear-resisting sheet, a sealing strip and asealing lining from outside to inside in sequence through glue; the sealing structure is divided into three sections from the outer ring to the inside in sequence along the rotation direction of the vortex tooth by the partition plates which are arranged in the sealing groove: a low -pressure sealing section, a medium-pressure sealing section and a high-pressure sealing section; in terms of length, the low-pressure sealing section is larger than the medium-pressure sealing section, the medium-pressure sealing section is larger than the high-pressure sealing section; the partition plates playsan air-sealing role on the sealing groove. The vortex tooth and the sealing structure are designed according to different pressures of the vortex tooth, the gas flow in the tooth grooves is reasonablyplanned, the sealing effect of the sealing structure is improved, and radial leakage is effectively controlled.
