Description
Technical field
The utility model belongs to urban operating mechanism technical field, is specifically related to a kind of self-lock manhole cover.
Background technology
The various well lids that use on road at present, generally all directly cover, and without any being locked to structure, very easily by people, arbitrarily being opened, damage or lose.Common people difficultly just can not take out, and well lid is easily stolen.Well lid originally rolls in process in being traveling vehicle simultaneously, likely produce the displacement of level and vertical direction, cause well lid projection or horizontal movement distortion, affect path formation, once vehicle, roll well lid and easily turn on one's side and even dished out outside well, have great potential safety hazard.
General well cover bottom is all artificial with brick one-tenth, the one, and lack of standardization nonstandard, the 2nd, through vehicle, roll easy distortion on the ground, there is the danger of caving in, labour cost is high now, engineering length consuming time, increase cost.
Therefore, provide the letter of a kind of structure simple, easy to operate, firm and durable, long service life, applied widely, safe and reliable, to install quick and conveniently, cost is low, and the self-lock manhole cover of short construction period has wide market prospects.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the letter of a kind of structure simple, easy to operate, firm and durable, and long service life, applied widely, safe and reliable, to install quick and conveniently, cost is low, the self-lock manhole cover of short construction period.
The technical solution of the utility model is such realization: a kind of self-lock manhole cover, comprise the well cover with convex-concave platform, be arranged on the well lid of well cover convex-concave platform top, the center of described well lid is movably installed with swivel head, the bottom of swivel head is movably installed with movable rod, movable rod is connected with well lid tapered end by positioning bolt, at well, puts and is provided with the locked groove cooperatively interacting with well lid tapered end.
Described swivel head below is installed with turntable, on turntable, be movably installed with four movable rods, four movable rods all by positioning bolt respectively at four well lid tapered end active links, between turntable and movable rod also by positioning bolt active link.
The top of described swivel head offers interior five side's grooves.
The center of described well lid is offered porose, and swivel head is movably arranged in this hole, and the termination, top of swivel head is not less than termination, bottom, is provided with lock bolt below swivel head.
Described locked groove is cirque structure, and locked groove is opened in the inner side of well cover.
Described well cover inner side is installed with reinforcing bar helper.
The utlity model has following good effect: the letter of the utility model structure is simple, easy to operate, comprise the well cover with convex-concave platform, be arranged on the well lid of well cover convex-concave platform top, the center of described well lid is movably installed with swivel head, the bottom of swivel head is movably installed with movable rod, movable rod is connected with well lid tapered end by positioning bolt, at well, put and be provided with the locked groove cooperatively interacting with well lid tapered end, this product in use, this product only has with associated spanner and could open, there is self-locking open function, well cover adopts reinforced concrete prefabricated or other materials to make, well is arranged with the convex-concave platform of holder well lid, well depth no matter, can assemble, well lid is furnished with specialized opener, there is self-locking open function, safe and reliable, after preventing that automobile from rolling, well lid easily rollover is even dished out outside well, avoid hurting sb.'s feelings and traffic accident generation, and this well lid is at inspection shaft, coal gas, tap water, the industries such as communication are all suitable for, the scope of application is very wide, actual use cost is low, reduces labour cost, and construction period is shortened greatly, in every layer of well cover, be all provided with reinforcing bar helper, be beneficial to and install and maintenance, the utility model easily operates, reduce construction cost, operate fast and convenient.
