  • Patent number: 8100705
    Abstract: A safety door for use with a rotatable power supply socket having a mounting base with plugging holes therein. The safety door includes first, second and third sliding parts, and an elastic assembly. The safety door includes three rectangular plugging holes, a left-hand, middle and right-hand plugging hole, and two ground plugging holes, upper and lower. While sliding in a rail slot of the mounting base, the first sliding part can block the left-hand plugging hole while sliding along the left-right direction, the second sliding part can block the right-hand plugging hole while sliding along the left-right direction; the third sliding part can block or expose the middle plugging hole while sliding along the left-right direction. The elastic assembly includes a first elastic part for providing returning elastic force to the first sliding part and a second elastic part for providing returning elastic force to the second sliding part.
