Embodiment
Below in conjunction with accompanying drawing, the embodiment of utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 1 and Figure 2, the utility model provides a kind of suspension insulator anti-ice-flashing guard shield, and this anti-ice-flashing guard shield comprises ball-eye 1, the rotation collar 2, connecting rod 3 and blade 4;
The described rotation collar is installed on described ball-eye, and described connecting rod is connected with the described rotation collar, and described blade is connected with described connecting rod.
As shown in Figure 3, the described rotation collar is comprised of the semicircle collar 5 and gland 6, and described two glands are connected with two end points of the described semicircle collar respectively, and with the line of two end points of the described semicircle collar in same level.
The described semicircle collar is two, and two described semicircle collars are symmetrical structure.Described gland is four, the line of two end points of described gland and the described semicircle collar is in same level, and centered by the line of two end points of the described semicircle collar, symmetrical between two, one end of described gland is connected with the described semicircle collar, and two glands of described symmetry are fixedly connected with by bolt 7.The described semicircle collar and can water and build up an integral body with the connected mode of two glands of the semicircle collar, also can be welded into a whole, and can be also the connection of any-mode.
The cross section of described connecting rod is triangle.Connecting rod described in the utility model embodiment is that triangle is that described connecting rod is frangibility not because the windward side of the triangle shape peculiar with respect to quadrangle etc. is less.
