Well head is damaged, road surface plane vicious cycle.
Utility model content
The technical problems to be solved in the utility model is that offer is a kind of to be hardly damaged and is subject to generation noise during load little
Quiet anti-settling manhole cover.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of quiet anti-settling manhole cover, includes lid and fixed frame, is chain connection between described lid and fixed frame,
Described fixed frame inwall is in that the conical surface is arranged, and described lid and fixed frame junction are provided with anti-tip self-locking mechanism.
Preferably, described lid bottom surface is provided with reinforcement framework, further increase the intensity of lid so that well lid more
Plus it is durable.
Preferably, described reinforcement framework includes the first stiffening ring, the second stiffening ring and stiffener.
Preferably, the radius of described first stiffening ring is less than the radius of the second stiffening ring.
Preferably, the center of circle of described first stiffening ring and the second stiffening ring is respectively positioned in lid bottom center.
Preferably, described stiffener is provided with one or more.
Preferably, described stiffener is around the array setting of lid bottom center.
Preferably, anti-settling second protection block is provided with described fixed frame inwall, provides support force for lid, prevent
There is sedimentation phenomenon in lid.
Preferably, described anti-settling second protection block is provided with four pieces.
Preferably, described anti-settling second protection block is located at four corners of fixed frame inwall respectively.
The beneficial effects of the utility model are: this quiet anti-settling manhole cover by the inwall of fixed frame is designed to the conical surface,
By traditional well lid bearing mode for stiff dough contact made conical surface friction into, from traditional well lid in bearing load vertical shear to
Distribution has made transverse radial power into distribution, and the well lid after change is subject to the noise producing during load little, to living in surrounding
Resident brings a quiet environment, and this quiet anti-settling manhole cover is due to changing power to not resulting in road surface breakage, well lid
Damage phenomenon, extend well lid service life, reduce maintenance rate, substantially reduce human cost；By connecting in lid and fixed frame
Place is provided with anti-tip self-locking mechanism, can prevent from opening generation during lid and overturn phenomenon.Additionally, lid bottom surface is provided with reinforcement
Framework, further increases the intensity of lid so that well lid is more durable；Anti-settling second protection is provided with fixed frame inwall
Block, provides support force for lid, prevents lid from sedimentation phenomenon occurring.
