The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of the specific embodiment.
Unless separately there is other clearly to represent, otherwise in whole specification sheets and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or component part, and do not get rid of other element or other component part.
As shown in Figures 1 to 4, according to the concrete structure of the fast open type manhole door of the utility model specific embodiment, comprise: doorframe 1, door body 2 and be connected the attaching parts of this doorframe 1 and door body 2, and locking piece, wherein, doorframe 1 and door body 2 form chain connection by attaching parts, make relative doorframe 1 flexible rotating of a body 2 open or close.When door body 2 is closed, by locking piece, lock, door body 2 need to unclamp locking piece, then beat opening door body 2 before opening.The doorframe 1 of this fast open type manhole door and door body 2 form chain connection, make the connecting portion of the two can not produce stifled ash or corrosion phenomena.
Wherein, doorframe 1 is ring-type, and its inner opening end is welded on ash bucket wallboard, and outward opening end has closure gasket groove, and for laying grommet type seals 11, when door body 2 lids are located at the outward opening end of doorframe 1, seal ring 11 contacts and seals with the surrounding outer rim of door body 2.
