When the conducting ring of the slip ring is used as a rotor and the electric brush is used as a stator, the outer structure drives the first cover plate 1 and the first shell 2 to rotate, the conducting ring shifting ring 501 drives the conducting ring transmission part 5 on the slip ring to synchronously rotate, and the electric brush transmission part 6 does not rotate.

It should be noted that the brushes of the slip ring may also be used as a rotor, and at this time, the conducting ring is used as a stator, and when the external structure drives the second housing 13 and the second cover 14 to rotate, the brush shifting ring 601 drives the brush transmission portion 6 on the slip ring to rotate synchronously, while the conducting ring transmission portion 5 does not rotate. At this time, the conducting ring transmission part 5 on the slip ring and the electric brush transmission part 6 on the slip ring relatively rotate, and the shielding sealing rotation transmission effect between the conducting ring transmission part 5 on the slip ring and the external environment of the shell and between the electric brush transmission part 6 on the slip ring and the external environment of the shell is realized by utilizing the dynamic sealing structure.
The static seal in the sealing structure of the slip ring in the market at present mostly adopts a sealing gasket, needs to be opened, and has long period and relatively high cost in the research and development stage; the invention aims to provide a shielding sealing structure with convenient installation and low cost, and realize the shielding and sealing effects in the work of the slip ring.
