The utility model discloses a pole-mounted circuit breaker shell sealing device, and relates to the technical field of electric power equipment sealing. The circuit breaker comprises a turnover mechanism, the output end of the turnover mechanism is provided with a circuit breaker body, and the top of the circuit breaker body is provided with a sealing groove. An elastic sealing assembly is arranged in an inner cavity of the circuit breaker body shell and comprises a first rotating shaft movably connected to the inner cavity of the circuit breaker body shell through a bearing seat, a first bevel gear fixedly connected with the surface of the first rotating shaft and a second bevel gear meshed with the surface of the first bevel gear. A plurality of groups of cams are driven by a symmetrically-arranged double-bevel-gear transmission system, the circumferential uniform pressure application of the sealing ring is realized, the involute profile of the cam ensures the linear propulsion of the ejector block, the sealing ring obtains accurate and controllable radial compression amount, the pressure gradient caused by traditional single-point compression is eliminated, and the pressure uniformity of a sealing interface is improved.
