Facilitate, practical manhole cover.
The utility model is realized in the following way:
A kind of manhole cover, it is characterised in that: described including well lid cover board, the well lid seat ring matched with well lid cover board
The inner sidewall of well lid seat ring is equipped with sliding block guide groove；The bottom surface of the well lid cover board has extended to form attachment base, the attachment base
Upper to have the hinged sliding block of cover board by cover board pin connection, the hinged sliding block of cover board, can relative to attachment base using cover board pin as fulcrum
To rotate 180 degree；When well lid cover board is connected on well lid seat ring, the hinged sliding block of cover board is matched with sliding block guide groove；
When well lid cover plate closing, the hinged sliding block of gravity lower cover plate of well lid cover board will be downward along sliding block guide groove
Movement, among well lid cover board is completely into well lid seat ring；When well lid cover board is opened, due to the effect of external force, well lid lid
Plate will rotate angle by the center of circle of cover board pin, and with the increase of rotation angle, the surface of well lid cover board will be generated with well lid seat ring
Interference point, external force continue effect under, using well lid cover board as lever, interference point is fulcrum, will generate one in the short end of lever
A upward power, this power pass to the hinged sliding block of cover board by cover board pin, and the hinged sliding block of cover board will under the action of this power
It is moved upwards along sliding block guide groove, so that well lid cover board can continue to revolve using cover board pin as the center of circle, until the table of well lid cover board
Face is contacted with road surface.
The utility model has the beneficial effects that: structure is simple, processing assembling is easy, reliable operation；Well lid lid when unlatching
Plate can overturn 180 degree or more, and well lid cover board and road surface are smooth, will not cause to stop to well head is checked, eliminate construction safety
Hidden danger.
