Wave-shaped sealing ring

The utility model relates to the technical field of sealing rings, in particular to a waveform sealing ring. The utility model provides a wave-shaped sealing ring which comprises a sealing ring body, and a wave-shaped inner ring is arranged on the inner side of the sealing ring body. The corrugated outer ring is arranged on the outer side of the sealing ring body; the upper contact ring is arranged at the top of the sealing ring body; a circular groove is formed in the bottom of the sealing ring body, and the lower contact ring is arranged in the circular groove; the elastic piece is used in the sealing ring body; the multiple metal rods are evenly and annularly arranged in the sealing ring body at intervals. The contact area of the sealing ring and the mounting groove is increased through the upper contact ring, and meanwhile the contact area of the sealing ring and the rotating shaft is reduced due to the fact that the waveform inner ring makes contact with the outer side of the shaft, so that the situation
