Abstract

The invention belongs to the technical field of climbing shoes, and particularly relates to climbing power-assisted shoe equipment based on magnet universal joint driving, which comprises a driving mechanism, a pressure mechanism and an air storage tank, wherein in the climbing process, a vamp can be inclined upwards relatively; at the moment, the swinging teeth can tilt backwards under the action of gravity; under the action of the limiting teeth, the swinging angles of the fan-shaped teeth and the swinging teeth are fixed; then the swing teeth are meshed with the ground; the antiskid effect is achieved. Meanwhile, high-pressure gas in the gas storage tank flows into the power-assisted shell through the gas compression pipe; when the power-assisted cylinder is contacted with the ground, downward pressure is applied to the ground; thereby enabling the power-assisted shoe to be acted by an upward force; thereby achieving the effect of power assistance. When jumping, the magnetic push plate moves downwards to generate repulsive force to the magnets arranged at the upper ends of the outer ring and the middle ring of the universal joint, so that the power-assisted shoes and the legs cannot swing easily; thereby achieving the effect of preventing sprain.
