Abstract：
 The magnetic adsorption mechanism of crawler wall-climbing robot comprises adsorption magnetic circuit portion, coupling mechanism portion and shifting-restoring mechanism, the shifting-restoring mechanism mainly comprises core shaft, bearing, returning spring and shifting lever, its permanent magnet adopts a cylindrical body magnetized along radial direction, and is placed in the central through hole of a rectangular magnetic yoke, and can be freely rotated, and said magnetic yoke is separated into symmetrical two halves by magnet-insulating body along its centre, said shifting-lever is connected with permanent magnet by means of core shaft. Said invention process bistable characteristics-magnetic adsorption state and magnetic short circuit state, between two states its switching-oven control is convenient.
