Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
Refer to Fig. 1 to Fig. 3, a kind of safety manhole cover, including manhole cover body 1, annular wells seat 2 and projection 3, manhole cover body 1 includes 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 accommodation chamber 21 holding upper cover 11 and the cavity 22 coordinated with annular protrusion 12 plug-in mounting, 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 and the projection 3 being located at cavity 22 inwall are slidably matched.
During operation, the annular protrusion 12 of manhole cover body 1 is docked with cavity 22, and make the projection 3 being located at cavity 22 inwall enter maze trough 4 by maze trough 4 one end connected with annular protrusion 12 bottom, one direction rotary upper cover 11 afterwards, projection 3 is made to move until projection 3 contacts with the other end cell wall of maze trough 4 along maze trough 4 conduit, it is understandable that, maze trough 4 is the cell body at least possessing a rotation angle position, after projection 3 snaps in maze trough 4 other end, rotation angle position can stop spacing projection 3, it is thus possible to prevent the revolution of manhole cover body 1, manhole cover body 1 and annular wells seat 2 is made to lock.And, it is in the well lid 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 penetrate into by rainwater-proof, it is to avoid maze trough 4 and projection 3, by corrosion, facilitate the maintenance of well lid.
Above-mentioned maze trough 4 includes the inlet slot section 41, link slot section and the semienclosed slot section 42 that are sequentially communicated, link slot section is connected formation one corner part with the connectivity part of inlet slot section 41, link slot section is connected formation one corner part with the connectivity part of semienclosed slot section 42, steering resistance can be strengthened in the junction of link slot section with the junction of inlet slot section 41, link slot section and semienclosed slot section 42 by the setting of above-mentioned two corner part, make when manhole cover body 1 is turned round, corner part can stop spacing projection 3, thus preventing the revolution of manhole cover body 1 further.Additionally, link slot section also can be set to curvilinear groove section.
As a kind of preferred embodiment, link slot section in the present embodiment has plural horizontal guide groove 43 and vertical guide groove 44, horizontal guide groove 43 and vertical guide groove 44 is connected successively alternately between inlet slot section 41 and semienclosed slot section 42, and horizontal guide groove 43 and the linking of vertical guide groove 44 junction form one 90 ° of corner parts, so, when manhole cover body 1 is turned round, the resistance of projection 3 is strengthened by 90 ° of corner parts, prevent the revolution of manhole cover body 1 further, thus obtaining better anti-theft effect.
In order to prevent manhole cover body 1 from turning round further, the anti-inversion organization that projection 3 can be hindered to move can be set in above-mentioned semienclosed slot section 42, when manhole cover body 1 is turned round, this anti-inversion organization can abut cooperation with projection 3, projection 3 is formed certain resistance, so that the turning power being applied in manhole cover body 1 strengthens, 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 hindering the anti-inversion organization that projection 3 moves, and make protruding 5 to be arranged at intervals on the cell wall of semienclosed slot section 42, naturally it is also possible to it is that projection 5 or other structure of other quantity is fixed on the diverse location of cell wall.Projection 5 in the present embodiment abuts cooperation with projection 3, it is possible to provide certain resistance, stops projection 3 to turn round, thus stoping manhole cover body 1 to be turned round further.Additionally, the cell wall of semienclosed slot section 42 can be obliquely installed, it is convenient to operation.
In order to play better anti-theft effect, projection 3 and the quantity of maze trough 4 in the present embodiment are two, and projection 3 and maze trough 4 one_to_one corresponding are arranged, naturally it is also possible to set plural projection one to one 3 and maze trough 4.
Owing to manhole cover body 1 has constant weight, and during convenient operation, rotate upper cover 11, can at the symmetrical pulling apparatus in two, upper cover 11 top.And in order to save technique, reducing cost, the pulling apparatus in the present embodiment includes 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 are affixed, and during use, both hands are mentioned pull bar 6 and can be operated.Certainly, for the ease of operation, the setting of pulling apparatus be also not necessarily limited in the present embodiment record.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims.
