Abstract:
    The utility model discloses a mobile grounding device comprising guide rails, a trolley-type switch cabinet, a movable contact assembly, and a static contact assembly. Four roller wheels are disposed in the chassis of said trolley-type switch cabinet and move along two parallel guide rails to assist in grounding. The static contact assembly, against a cylindrical grounding rod as a main body, connects a connection pad, a connection plate and a grounding array and fastened by screws, the connection plate being connected with these two guide rails as a whole. The movable contact assembly is mounted on the right end surface of the trolley-type switch cabinet, consists of copper sheath, embedded block, spring ring and base, and is provided with an axially-arranged through-hole having elastic pre-shrinking aperture. The axially-arranged through-hole shares the same axial line with and has matching size with the grounding rod. The movable contact assembly engages with the grounding rod for grounding with the movement of the trolley-type switch cabinet. The utility model has the advantages of large contact area and reliable and safe grounding, and is particularly suitable for the use as grounding device for mobile device.
