In the prior art, well lid mostly uses iron chains or hinge-coupled method, cannot be integrated well lid and walling crib lock, be easy
It opens, iron chains, hinge can be prized and be broken with drill rod, anti-theft effect is little.
Summary of the invention
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, design is closed
Reason, rotary safe manhole cover easy to use.
In order to achieve the above purposes, the technical solution adopted by the utility model is: well seat, manhole cover body, casing, connecting rod,
Swinging mounting, first rotating shaft, the first locking bar, the second shaft, the second locking bar, jack, lock pin, handle；The manhole cover body
The inner hole of outer circle and well seat, manhole cover body are set on the step of manhole cover body；The center of the manhole cover body is fixed
There is casing, connecting rod is inserted in casing, the bottom of connecting rod is fixed with swinging mounting, and the both ends of swinging mounting are separately installed with
One end of first rotating shaft and the second shaft, the first locking bar and the second locking bar is connect with first rotating shaft and the second shaft respectively；It is described
Connecting rod in be provided with jack, lock pin is combined in jack, the upper end of lock pin is fixed with handle.
Preferably, the step contact position of the manhole cover body and well seat is provided with rubber ring.
Preferably, being provided with lightening hole on the well seat.
Preferably, the bottom of the well seat and the distance between the first locking bar or the second locking bar are H, and H is 10-
20mm。
Preferably, being provided with drainage hole in the manhole cover body.
When the utility model operates, lock pin is inserted into jack, rotational handle drives swinging mounting rotation, thus the first lock
One end of bar is rotated around first rotating shaft, and second locking bar one end is rotated around the second shaft, to realize the first locking bar and the second locking bar
Far from well seat, handle is rotated backward, then the first locking bar and the second locking bar protrude into the lower section of well seat, to lock well seat and well lid sheet
Body removes lock pin and handle；When in well rainwater occur it is counter gush when, between the bottom of well seat and the first locking bar or the second locking bar between
Gap allows manhole cover body that can only raise 1 ~ 2 centimetre in situ under the action of water pressure, will not be raised and be drifted away.
After adopting the above structure, the utility model is the beneficial effects are as follows: rotation anti-theft described in the utility model
Well lid could be opened using specific purpose tool, enhance anti-theft effect, and existing well lid center can improvement and installation, transformation
At low cost, the utility model has many advantages, such as that structure is simple, setting is reasonable, low manufacture cost.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the structure chart of the utility model lockup state；
