The road safety who adopts this design to be favorable to the pedestrians and vehicles reduces the stolen risk of well lid, has increased the degree of difficulty of opening the well lid, has improved the factor of safety of well lid, has also improved the life of well lid to a certain extent, has reduced holistic social cost.
Description
Technical field
The utility model relates to a kind of inspection well cover, especially a kind of anti-stealing manhole cover.
Background technology
Along with the progress of modernization science and technology civilization, and the sharply increase of population, the underground space rate in city improves gradually, also just more extensive to the construction of sewer, and it is more and more important that the safety of the antitheft and road pedestrian vehicle of inspection well cover shows.And the daily middle lid of existing well lid is easily easily stolen, lacking lid very easily causes Pedestrians and vehicles to drop in inspection shaft; The stolen probability of lid is large, often removes put back to base, and frictional force is large, decreases the application life of well lid, adds social cost; Base and lid are all circular in addition, are easily subjected to displacement, and therefore well lid exists very large Improvement requirement.
Summary of the invention
For solving the problem, the utility model provides a kind of anti-stealing manhole cover.
The technical solution of the utility model: anti-stealing manhole cover, comprises lid and base, it is characterized in that: described lid is circular and is provided with outward extending projection, and the lid opposite side that described projection is corresponding has inner fovea part; Described base circle wall is provided with first groove corresponding with projection and the jut corresponding with inner fovea part; Described projection is provided with squash type latch lock, and described first groove is provided with the locked groove corresponding with squash type latch lock.
Lid is with projection and inner fovea part, and base is provided with and projection, the first groove, lug boss that inner fovea part is corresponding, and the Position Design cooperatively interacted like this, can prevent in use lid from rotating displacement, reduces the wearing and tearing with base, increases application life; The existence of base outer layer positioning through hole and base back surface detent, makes base contact very well with cement road ground etc., increases firmness; Global design is unfavorable for that stealer steals lid and base, adds the difficulty of stealing lid.
Further, described squash type latch lock forms by with the sleeve of base plate, lock core, latch plate, spring and jam plate, the main body two ends of described lock core are respectively equipped with lock pin and button, described lock pin be provided with can relative to subject activity latch plate, be provided with spring between described latch plate and button; Described jam plate is fixedly mounted on locked groove surface, and this jam plate is provided with the lockhole corresponding with lock pin, and described sleeve is fixed on projection by base plate.
Further, the epitaxial layer of described base is arranged with positioning through hole, between base side wall and epitaxial layer, is provided with delta tab, be crisscross arranged between this delta tab and positioning through hole; The bottom surface of described base is provided with detent.When delta tab is convenient to install, the lift of base, improves the endurance strength of sidewall, and positioning through hole and detent are convenient to install location.
Further, the upper surface of described lid is also provided with circular protrusions block, and the height of described circular protrusions presents arc from high to low from lid central point to cover edge, and the outer of lid upper surface is provided with strip projected parts block.Such being designed with of employing of lid upper surface is beneficial to timely draining profit sand.
Further, rubber bump protection ring is provided with between described lid and base.The setting of rubber bump protection ring, can improve the planeness between lid and base, reduces noise when car crosses, plays shockproof noise control effect.
Further, described positioning through hole is oval.
The improvement of anti-stealing manhole cover: 1. well lid bolt-type designs, time closed, in the whole inserted base of lid, prevents lid from being pried open from the side with instrument by people.2. lid is with special squash type latch lock, only has special key to open.3. there is radian in lid front, edge decorative pattern opening Design, and timely draining profit is husky.4. with shockproof noise-reducing design, base built-in rubber bump protection ring, can improve the planeness of well lid, reduces noise when car crosses.5. lid is with Position Design, prevents in use lid from rotating displacement, reduces the wearing and tearing with base, increases application life.6. base Position Design, the multiple positioning through hole of base edge, base back surface also has detent, and base is contacted very well with cement etc., increases firmness.
The beneficial effects of the utility model: adopt the design to be conducive to the road safety of Pedestrians and vehicles, reduce the stolen risk of well lid, add the difficulty opening well lid, improve the safety factor of well lid, also improve the application life of well lid to a certain extent, decrease overall social cost.
