As a kind of preferred version, described ceramic packing is cement ceramic packing.
The beneficial effects of the utility model:
The utility model umbrella ring adopts ceramic umbrella ring, and ceramic umbrella ring surface is smooth is easy to cleaning, and umbrella ring upper surface is downward-sloping gradually to the periphery from middle part in addition; End gold utensil is that upper end is little, lower end large truncated cone-shaped end gold utensil; When running into the rainy day, rainwater starts flowing along head end gold utensil, flows on end gold utensil always, then fall along the inclined plane of end gold utensil through umbrella ring, can not rest on end gold utensil, and in flow process, rinse out the attachment on umbrella ring and end gold utensil.The effect of its lower end line post protected in addition by up-small and down-big truncated cone-shaped end gold utensil.
The utility model center pole upper end is provided with fixture block, and described fixture block side is provided with annular groove, and fixture block is arranged in the mounting groove bottom head end gold utensil, is provided with ceramic packing in the space between the mounting groove bottom fixture block and head end gold utensil; Ceramic packing can select cement ceramic packing, and fixture block and head end gold utensil link together by cement ceramic packing closely, and cement is filled in the annular groove of fixture block side, makes fixture block and more firm the linking together of head end gold utensil, increases and bears intensity.
The utility model head end gold utensil outer rim is provided with electric current releasing structure, and end gold utensil lower end is provided with line post, and line post top is fixed with suction arcing device by nut; Effectively can avoid the problem of lightning-caused breaking.
