Side forms rack pinion pair with the drive rod for being symmetrically disposed on its two sides, and two drive rods are set to below well lid and realize with it
It is located at the radial limit in same sagittal plane with driving wheel, two drive rods synchronize opposite or synchronous under the driving of driving wheel
Counter motion, drive rod outer end are adapted to the locating slot or location hole for being radially opened in walling crib inner wall, driving wheel axle tip
Extend and the interface being adapted to dedicated key is formed by well lid.
The particular technique of the utility model is conceived also:
To be easy to implement the radial positioning of drive rod and the cooperation with locating slot or location hole, while reducing and being fabricated to
This, preferred technical solution is that the outer end of the drive rod is polished rod.
The main function of locating slot or location hole is to realize that drive rod outer end clamps positioning with it under the driving of driving wheel,
And then realize the positioning of well lid, positioning is clamped to be easy to implement drive rod outer end and its, preferred technical solution is that described determines
Position slot or location hole use strip groove or strip-shaped hole, and more preferably technical solution is that the locating slot or location hole use
The annular through groove of walling crib inner wall is opened in along same sagittal plane.
Convenient for the positioning of the retraction of drive rod, to make it, reason rotation is not deviate from from sliding sleeve excessively, and preferred technology is real
Existing means are that limited block is arranged with drive rod inner end interval and fixes with well lid lower surface.
The radial positioning of drive rod and well lid can be realized by a variety of existing mechanical systems, wherein more preferred skill
Art is achieved in that the middle part of the drive rod is slidably matched by sliding sleeve inner cavity, and sliding sleeve outer surface and well lid lower surface are solid
Fixed assembly.
It is inconvenient imitated that the shape of interface should meet, at the same be easy to cooperate with dedicated key and obtain more labour-saving unlatching and
Locking effect, preferred technical solution are that interface is columnar hole, and cross section is using in regular polygon, special-shaped level shape
A kind of or its combination.Opened and locking effect to obtain more labour-saving, the top of dedicated key can using cross bar, runner,
The various ways such as handle, crank, because it belongs to more common technical implementation way, details are not described herein by applicant.
In the description of the present invention, term " inside edge ", " lower section ", " two sides ", " radial direction ", " outer end ", " top ",
The orientation or positional relationship of the instructions such as " inner wall ", " lower surface ", " inner end " is to be based on the orientation or positional relationship shown in the drawings, only
It is to describe the utility model for the ease of simplified, rather than the device or element of indication or suggestion meaning must have specific side
Position is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Technological progress acquired by the utility model is:
1, the rack pinion pair that the utility model is formed by driving wheel, drive rod is as locking burglar-proof mechanism, simultaneously
It is equipped with unlatching or locking that dedicated key realizes well lid, effectively increases the cooperation intensity of well lid and walling crib, structure simply may be used
It leans on, solves the problems, such as that it is easy to be stolen and is easy to deviate walling crib under external force.
2, the structure of locating slot or location hole and drive rod outer end designs, unlatching and locking convenient for well lid.
3, using two point symmetry lockings under same sagittal plane, locking reliability has been effectively ensured, has met well lid and exists
Stress balance under lockup state.

Specific embodiment
The utility model is described further with reference to embodiments, but should not be construed as the limit to the utility model
Fixed, the protection scope of the utility model is subject to the content of claim record, any equivalent skill made according to specification
Art means replacement, all without departing from the protection scope of the utility model.
The overall structure of the present embodiment is as shown, including the walling crib 1 that earth's surface is fixed and be opened on basis, is covered on
1 inside edge of walling crib and the well lid 2 that seam allowance cooperation is realized with it；It is equipped with radial positioning below well lid 2 and coaxially rotates and matches
The driving wheel 4 of conjunction, 4 outside of driving wheel form rack pinion pair, two drive rods with the drive rod 5 for being symmetrically disposed on its two sides
5 are set to 2 lower section of well lid and realize the radial limit being located in same sagittal plane with driving wheel 4 with it, and two drive rods 5 are driving
The movement of opposite or synchronous backward, 5 outer end of drive rod and the positioning for being radially opened in 1 inner wall of walling crib are synchronized under the driving of wheel 4
Slot or location hole 7 are adapted to, and 4 axle tip of driving wheel, which extends and passes through well lid 2, forms the interface 3 being adapted to dedicated key.
The outer end of the drive rod 5 is polished rod.
The locating slot or location hole 7 are using the annular through groove for being opened in 1 inner wall of walling crib along same sagittal plane.
Limited block 8 is arranged with 5 inner end interval of drive rod and fixes with 2 lower surface of well lid.
The middle part of the drive rod 5 is slidably matched by 6 inner cavity of sliding sleeve, and 6 outer surface of sliding sleeve is fixed with 2 lower surface of well lid
Assembly.
Interface 3 is columnar hole, and cross section uses equilateral triangle.To obtain more labour-saving unlatching and locking effect, specially
It can be realized using various ways such as cross bar, runner, handle, cranks because it belongs to more common technology with the top of key
Mode, details are not described herein by applicant.
The working principle of the present embodiment is as follows:
When needing open manhole cover 2, interface 3 is inserted into the lower end of dedicated key and is rotated, until drive rod inner end and limit
Block 8 no longer rotates after contacting, and 5 outer end of drive rod is detached from from locating slot or location hole 7, can take well lid 2 from walling crib 1
Under, when such as needing closed-in well lid, interface 3 is inserted into dedicated key lower end and turns to 5 outer end of drive rod enters locating slot or fixed
Position hole 7, can be completed the locking of well lid 2 Yu walling crib 1.
