Lower offer support, it is to avoid occur unexpected manhole cover supporting structure.
The purpose of the present invention can be realized by following technical proposal：A kind of manhole cover supporting structure, including manhole, manhole
Including the front panel being parallel to each other and squab panel, the cover plate being hinged with squab panel by hinge is stamped on manhole, it is characterised in that：
Cover plate bottom surface is provided with articulated section close to front panel, includes the support frame of triangle body frame structure, it is in three that support frame, which includes three,
The hack lever one of Angle connection, the hack lever two of three connections triangular in shape, two support bars for being parallel to each other and parallel with support bar
Rotating shaft, support frame is hinged on articulated section by rotating shaft, and rotating shaft is parallel with cover plate and front panel, and can be started around hinge
Cover plate, and turned up support frame around rotating shaft, a support bar is against on cover plate bottom surface, and make a hack lever one and a hack lever
Two are supported in front panel, can also surround rotating shaft varus support frame, another support bar is against on cover plate bottom surface, and make cover plate
In normal opening-closing structure.
In use, start cover plate around hinge, and turned up support frame around rotating shaft, a support bar is against cover plate bottom surface
On, and a hack lever one and a hack lever two is supported in front panel, therefore formed using support frame in cover plate bottom
Support, it is to avoid cause cover plate to cover due to unexpected, and during operation, support bar push-and-pull cover plate can be held so that support bar is also
Play handle effect.
In a kind of above-mentioned manhole cover supporting structure, three length of hack lever one are identical and form equilateral triangle structure,
Three length of hack lever two are identical and form equilateral triangle structure.
Therefore structure is compacter.
In a kind of above-mentioned manhole cover supporting structure, two described support bars, and the He of hack lever one away from rotating shaft
Activity is cased with sheath on hack lever two.
Therefore it can cause support bar and hack lever one and hack lever two away from rotating shaft that there is handle function using sheath, make
With more facilitate.
In a kind of above-mentioned manhole cover supporting structure, described support bar has magnetic, and cover plate bottom surface is provided with two
Strip magnet, and can be turned up around rotating shaft or varus support frame, make a support bar absorption on a magnetic patch, or make another
Support bar is adsorbed on another magnetic patch.
Therefore connection is more stablized.
Compared with prior art, the invention has the advantages that：
In use, start cover plate around hinge, and turned up support frame around rotating shaft, a support bar is against cover plate bottom surface
On, and a hack lever one and a hack lever two is supported in front panel, therefore formed using support frame in cover plate bottom
Support, it is to avoid cause cover plate to cover due to unexpected, and during operation, support bar push-and-pull cover plate can be held so that support bar is also
Play handle effect.
Brief description of the drawings
