Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further:
Refer to Fig. 1 to Fig. 3, a kind of anti-stealing manhole cover device, comprise manhole cover body 1, annular wells seat 2 and convex post 3, manhole cover body 1 comprises upper cover 11, annular protrusion 12 and maze trough 4, upper cover 11 covers in annular protrusion 12 top, annular wells seat 2 has the container cavity 21 holding upper cover 11 and inserts the cavity 22 of assembling conjunction with annular protrusion 12, maze trough 4 is located on annular protrusion 12 periphery wall, bottom the through annular protrusion 12 in one end of maze trough 4, the other end of maze trough 4 is on annular protrusion 12 periphery wall, and this maze trough 4 is slidably matched with the convex post 3 being located at cavity 22 inwall.
During operation, the annular protrusion 12 of manhole cover body 1 is docked with cavity 22, and make the convex post 3 being located at cavity 22 inwall enter maze trough 4 by maze trough 4 one end being connected with annular protrusion 12 bottom, one direction rotary upper cover 11 afterwards, convex post 3 is made to move until convex post 3 contacts with the other end cell wall of maze trough 4 along maze trough 4 groove road, it is understandable that, maze trough 4 is the groove body at least possessing a rotation angle position, after convex post 3 blocks maze trough 4 the other end, rotation angle position can stop limit convex post 3, it is thus possible to prevent the revolution of manhole cover body 1, manhole cover body 1 and annular wells seat 2 are locked. and, the well lid being under locking state, owing to maze trough 4 is between annular protrusion 12 and annular wells seat 2, not only not easily find, play anti-theft function, and maze trough 4 is embedded on annular protrusion 12 periphery wall, and annular protrusion 12 top is covered with upper cover 11, can infiltrate by anti-rainwater, avoid maze trough 4 and convex post 3 by corrosion, facilitate the maintenance of well lid.
Above-mentioned maze trough 4 comprises the inlet slot section 41, connective slot section and the semiclosed groove section 42 that are connected successively, connective slot section is connected formation one corner part with the connectivity part of inlet slot section 41, connective slot section is connected formation one corner part with the connectivity part of semiclosed groove section 42, steering resistance can be strengthened in the junction of the junction of connective slot section and inlet slot section 41, connective slot section and semiclosed groove section 42 by the setting of above-mentioned two corner parts, make when manhole cover body 1 is turned round, corner part can stop limit convex post 3, thus prevents the revolution of manhole cover body 1 further. In addition, connective slot section also can be set to curvilinear groove section.
As a kind of preferred embodiment, connective slot section in the present embodiment has the horizontal guide groove 43 of two or more and erects to guide groove 44, between inlet slot section 41 and semiclosed groove section 42, it is connected horizontal guide groove 43 successively alternately and erects to guide groove 44, and horizontal guide groove 43 forms one 90 �� of corner parts with erecting to be connected to guide groove 44 junction, so, when manhole cover body 1 is turned round, the resistance of convex post 3 is strengthened by 90 �� of corner parts, prevent the revolution of manhole cover body 1 further, thus obtain better anti-theft effect.
In order to prevent manhole cover body 1 from turning round further, the anti-inversion organization that convex post 3 can be hindered to move can be set in above-mentioned semiclosed groove section 42, when manhole cover body 1 is turned round, this anti-inversion organization can coordinate to connecing with convex post 3, convex post 3 is formed certain resistance, thus the turning force being applied in manhole cover body 1 is strengthened, the revolution difficulty of manhole cover body 1 can be made to increase.
As a kind of preferred embodiment, in the present embodiment is three projections 5 for the anti-inversion organization hindering convex post 3 to move, and make protruding 5 to be arranged at intervals on the cell wall of semiclosed groove section 42, naturally it is also possible to it is that projection 5 or other structure of other quantity is fixed on the different positions of cell wall. Projection 5 in the present embodiment coordinates to connecing with convex post 3, can provide certain resistance, stops convex post 3 to turn round, thus stops manhole cover body 1 to be turned round further. In addition, the cell wall of semiclosed groove section 42 can be obliquely installed, and is convenient to operation.
In order to play better anti-theft effect, convex post 3 and the quantity of maze trough 4 in the present embodiment are two, and convex post 3 and maze trough 4 one_to_one corresponding are arranged, naturally it is also possible to the convex one to one post 3 of setting two or more and maze trough 4.
Owing to manhole cover body 1 has certainweight, and during handled easily, rotate upper cover 11, can at the symmetrical pulling apparatus in two, upper cover 11 top. And in order to save technique, reduce costs, the pulling apparatus in the present embodiment comprises a groove 61 and pull bar 6, and pull bar 6 is across groove 61 top, and pull bar 6 two ends and upper cover 11 top connect admittedly, it may also be useful to time both hands mention pull bar 6 and can operate. Certainly, for the ease of operation, the setting of pulling apparatus be also not limited in the present embodiment record.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and these all changes and deformation all should belong within the protection domain of the claims in the present invention.
