Description
Technical field
The utility model relates to a kind of well lid fields, are specifically related to a kind of well lid.
Background technique
Well lid is article common in municipal works, being continuously increased, extend and developing with urban road, sewer well
Lid increasingly increases severely.Casting iron well lid is widely used because its intensity is high, the service life is long as well cover for sewer, but the upper well of road
Lid is rolled by automobile for a long time be easy to cause well lid to loosen, and ring support fitting is not tight, and tire can not well lid collision when vehicle rolls
Noise is generated, environmental pollution is caused, when serious, well lid even falls off, and jeopardizes vehicle and pedestrian safety.
Utility model content
The utility model is in order to solve the above technical problems, provide a kind of sound construction, safe and reliable, waterproof noise control, lock
Right strong well lid.
In order to solve the above technical problems, a kind of well lid provided by the utility model, including well lid and crib, the well lid can
Flip lid ground is fastened on crib, and the well lid includes more than two sub- well lid mutually spliced, the crib be equipped with it is a plurality of and
The corresponding sub- crib of each sub- well lid, each sub- crib two sides are equipped with the cylindrical body locked groove that an opening is rectangle,
Each sub- well lid two sides are equipped with the cuboid closing piece to match with the locked groove, and the closing piece is by being equipped with rolling lead screw group
Part is fixed on the lower surface of each sub- well lid, and the ball screw includes screw rod, nut seat and steel ball, the nut seat with
Sub- well lid is fixedly connected, and described screw rod one end is set to inside the nut seat and sets in screw rod close to the end of sub- well lid lower surface
There is spring, the other end of the screw rod is fixedly connected with closing piece, it is also equipped with dismountable crossbeam between each sub- crib,
Each crossbeam both ends are equipped with the groove for placing crossbeam.
Further improved to be: there are four the sub- well lid and sub- crib are all provided with, the crossbeam is equipped with three.
By using above-mentioned technical solution, the beneficial effects of the utility model are: set on the sub- well lid of the utility model
Closing piece is directed at set locked groove insertion on sub- crib, the gravity that closing piece is pushed after entering locked groove by well lid, and screw rod is to spiral shell
Base contract, screw rod drive closing piece rotation angle and are caught in inside locked groove, and formation is self-locking, and structure is simple, and well lid and crib are locked
