Blind patch leads to turnbuckle and carries out tension sealing with manhole pressing plate.
A kind of more hinge pivoted arm manhole door structures of alkali collection drum of the utility model, the cover plate for manhole top have lid
Plate otic placode, the cover board connection bolt is through cover board otic placode, so that being formed between cover plate for manhole and cover board connection bolt movable
Connection.
A kind of more hinge pivoted arm manhole door structures of alkali collection drum of the utility model, the cover plate for manhole bottom have T
Type groove seat, the T-slot seat are detachably connected with turnbuckle.
A kind of more hinge pivoted arm manhole door structures of alkali collection drum of the utility model, the L-type of the pivoted arm otic placode both sides
Limiting plate and spacer pin are respectively provided on pivoted arm.
A kind of more hinge pivoted arm manhole door structures of alkali collection drum of the utility model, the Y types pivoted arm connect including bolt
Socket part and pivoted arm connecting portion, the pivoted arm connecting portion take the shape of the letter U structure, and the hollow part of the U-shaped structure forms the dress of L-type pivoted arm
Enter space.
A kind of more hinge pivoted arm manhole door structures of alkali collection drum of the utility model, the bolt head of the turnbuckle are
Square structure.
According to above-mentioned technical proposal, the beneficial effects of the utility model are：It is proposed a kind of more hinge pivoted arms of alkali collection drum
Monaural plate hinge is changed to the more hinges of cantilever by manhole door structure, and set T-slot seat can with fast assembling-disassembling turnbuckle,
And cover plate for manhole can be moved horizontally and rotated, so as to improve the convenience of its opening and closing operations.
Description of the drawings
Fig. 1 is a kind of front view of the more hinge pivoted arm manhole door structures of alkali collection drum of the utility model；
Fig. 2 is a kind of top view of the more hinge pivoted arm manhole door structures of alkali collection drum of the utility model.
Specific embodiment
The utility model is further described with reference to specific embodiments and the drawings.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model
Such as the embodiment that Fig. 1-2 is a kind of more hinge pivoted arm manhole door structures of alkali collection drum of the utility model, a kind of alkali
The more hinge pivoted arm manhole door structures of drum are recycled, including：Drum 11 has manhole door opening, the manhole door on the drum 11
Cover plate for manhole 1 is covered at hole, the cover plate for manhole 1 connects bolt 4 by cover board and is connected with Y types pivoted arm 6, the Y types pivoted arm 6
