Lower facility and the safety for safeguarding highway communication, but due to various reasons, the loss of well lid or damage usually cause traffic accident, gently
Person's vehicle is spoken sarcastically wound, severe one car crash.Undesirable steals well lid for wealth of coveting a little in order to prevent, and design one kind is needed to prevent from stealing
The well lid of robber, to achieve the purpose that prevent undesirable from stealing well lid.
Utility model content
Problem to be solved in the utility model is to provide a kind of municipal administration for the above problem in the presence of the prior art
Engineering anti-stealing manhole cover, the flat shrapnel stretched out by well lid is stuck in the annular groove of well lid bearing prevents well lid from opening to reach
It opens, to solve the above-mentioned problems in the prior art.
To achieve the above object, the utility model uses the following technical solution：
A kind of municipal works anti-stealing manhole cover, including well lid bearing and the lid that is made of upper cover body and lower cover, lower cover
The bottom surface of body is placed on the circular platform being arranged on well lid bearing, and upper cover body edge is equipped with annular lug, in well lid bearing
Well head is provided with the ring-shaped platform of support annular lug, and the bottom surface of upper cover body is provided with upper annular groove, is set in the top surface of lower cover
It is equipped with the lower annular groove opposite with upper annular groove, after the bottom surface of upper cover body is contacted with the top surface of lower cover, makes annular groove and lower ring groove shape
The cavity circularized is provided with annular groove identical with the cavity height on well lid bearing, is set on the ring wall of cavity
Multiple vias communicated with annular groove are equipped with, rotation axis are installed in the center of cavity, the end face center of upper cover body is set
The straight slot communicated with cavity is set, the top of rotation axis is located in straight slot, and the gear being equipped on the rotating shaft in cavity turns
Dynamic component, is fixedly connected with several flat shrapnels on the gear runner assembly, flat shrapnel cavity in uniform distribution and
It can stretch into annular groove.
Compared with the prior art, the utility model has the advantages that：
1, the shrapnel stretched out by well lid is stuck in prevents well lid from opening in the groove of well lid bearing, and reaching prevents well lid quilt
The effect of pilferage.
2, simply by rotary motion axis, flat shrapnel is made to stretch out or be bent to achieve the purpose that block or open,
It is convenient, fast, it improves installation and checks efficiency.

Fig. 2 is the utility model lid cross-sectional view.
Fig. 3 is the utility model lid unlocking condition lower structure schematic diagram.
Specific implementation mode
In order to make, technological means of the utility model, creation characteristic, reached purpose and effect are more clear and are easy to
Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：
As shown in attached drawing 1, Fig. 2, a kind of municipal works anti-stealing manhole cover, including well lid bearing 1 and by upper cover body 2 and lower cover
The lid that body 3 is constituted, the bottom surface of lower cover 3 are placed on the circular platform 11 being arranged on well lid bearing 1, and 2 edge of upper cover body is set
There is annular lug 21, the well head of well lid bearing 1 is provided with the ring-shaped platform 12 of support annular lug 21, at the bottom of upper cover body 2
Face is provided with annular groove, and the lower annular groove opposite with upper annular groove, the bottom surface of upper cover body and lower cover are provided in the top surface of lower cover
Top surface contact after, the cavity 4 for making annular groove and lower ring groove shape circularize is provided with high with the cavity 4 on well lid bearing 1
Identical annular groove 13 is spent, multiple vias communicated with annular groove 13 are provided on the ring wall of cavity 4, in cavity 4
Center is equipped with rotation axis 41, and the end face center of upper cover body 2 is arranged the straight slot 22 communicated with cavity 4, rotation axis 41 it is upper
Portion is located in straight slot 22, and the gear runner assembly 42 in cavity 4, the gear runner assembly are equipped in rotation axis 41
Several flat shrapnels 43, preferably stainless steel material are fixedly connected on 42, the service life is longer, and flat shrapnel 43 is in cavity 4
In uniform distribution and can stretch into annular groove 13.
Utility model works principle is：When flat shrapnel is extend into the annular groove on well lid bearing, at well lid
It in clamping lock state, can not open, by the key turns rotation axis to match with rotation axis, among moving gear runner assembly
Bull gear drive makes the outer wall for being equipped with the i.e. gear runner assembly of gear ring being mutually engaged with gear wheel rotate, flat shrapnel is driven to turn
Dynamic, flat shrapnel is bent under the blocking of the ring wall of cavity, and when being against on the ring wall of cavity, well lid is in open state, can
With open manhole cover, then proceeding to rotary motion axis makes flat shrapnel stretch into annular groove again, completes clamping lock again.
