a kind of insulator mask, described insulator comprises that small diameter part divides the full skirt that divides periphery with small diameter part, it is characterized in that: described insulator mask comprises the first～three covering, described the first covering has a bottom surface, at middle part, described bottom surface, has a horizontal rectangular through-hole, one end of this rectangular through-hole forms opening in the edge of described bottom surface, the other end is semicircle, the diameter that this opening size and described insulator small diameter part divide is complementary, the semicircle side of described rectangular through-hole is surrounded by the first insulation barrier, described insulation barrier height is consistent with the careful footpath of described insulation height,
Described the second covering also has a bottom surface, the bottom surface of this bottom surface and the first covering hinged and its middle part one side be formed with an opening, in the inboard of this opening, be provided with the second insulation barrier, when described the second covering and the first covering closure, the semicircle place of described the second covering opening and the first covering rectangular through-hole surrounds the circle in a careful footpath of housing insulation jointly, and described first, second insulation barrier covers the careful footpath of described insulation jointly;
Described the 3rd covering is the insulation barrier of bottom with draw-in groove, one side the bottom surface of described the first covering is away from the described draw-in groove of being inserted into of opening.
Described the second covering is connected by the insulation pin with the first covering, and the second covering can rotate freely.
Described first and second insulation board surrounds cuboid or cylindrical when closed.
Described the 3rd covering height is a little more than the insulator whole height; By the insulator overall isolation, ensure operating personnel's personal safety.
Described the first covering, the second covering and the 3rd covering are made by insulating material, and insulating material can be the light weight insulating materials such as epoxy resin, polyvinyl chloride, polyethylene or polypropylene.
This insulator mask is applicable to covering of pin type, column type porcelain insulator.
This insulator shading tool, can guarantee beyond the safe distance energized conductor (especially pin type, column type porcelain insulator) is not tightly covered, and is simple to operate, can save and cover the operating time in a large number, improves the fail safe of hot line job.

Embodiment
Below in conjunction with accompanying drawing and the specific embodiment structure to insulator mask of the present utility model, be elaborated.
as Fig. 1, 2, shown in 3, a kind of insulator mask, described insulator comprise small diameter part divide 6 and small diameter part divide peripheral full skirt, it is characterized in that: described insulator mask comprises the first～three covering 1, 2, 3, described the first covering 1 has a bottom surface, at middle part, described bottom surface, has a horizontal rectangular through-hole 4, one end of this rectangular through-hole forms opening in the edge of described bottom surface, the other end is semicircle, this opening size and described insulator small diameter part divide 6 diameter to be complementary, the semicircle side of described rectangular through-hole is surrounded by the first insulation barrier 5, described insulation barrier height is highly consistent with the careful footpath 6 of described insulation,
Described the second covering 2 also has a bottom surface, the bottom surface of this bottom surface and the first covering 1 hinged and its middle part one side be formed with an opening, in the inboard of this opening, be provided with the second insulation barrier 7, when described the second covering 2 and the first covering 1 closure, the semicircle place of described the second covering opening and the first covering rectangular through-hole 4 surrounds the circle in a careful footpath 6 of housing insulation jointly, and described first, second insulation barrier 5,7 surrounds a cuboid and covers the careful footpath 6 of described insulation;
