Detailed description of the invention

Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.

As shown in the figure: the work well lid in embodiment mainly comprises walling crib 1 and well lid 2 two parts, walling crib 1 and well lid 2 are all designed to circle, the inner side edge of described walling crib 1 is provided with in 180 ° of symmetrical concave bayonet 1a and draw-in groove 1b, described well lid 2 outer side edges is provided with in 180 ° of symmetrical evagination buckle 2a and bayonet unit, described concave bayonet 1a inlays with evagination buckle 2a and coordinates, for locating the installation site of well lid 2; Described draw-in groove 1b coordinates with bayonet unit, is connected for being locked with walling crib 1 by well lid 2.

As shown in Fig. 2 ~ Fig. 4, in the utility model embodiment, described bayonet unit forms primarily of fixture block 3, cylindrical bars 4, hollow section 5 and handle 6; Described lid offers small sircle hole, and described cylindrical bars 4 is installed in small sircle hole and also can rotates freely, and described fixture block 3 is arranged on below well lid 2, and fixture block 3 is fixedly connected with cylindrical bars 4 lower end; Described hollow section 5 is arranged on above well lid 2, and hollow section 5 is fixedly connected with cylindrical bars 4 upper end; Described handle 6 is installed in hollow section 5, fixture block 3 can be driven to rotate by handle 6, fixture block 3 is snapped in or deviates from draw-in groove 1b, and can be mentioned by well lid 2 by fixture block 3.

As shown in Figure 5, in the utility model embodiment, the draw-in groove 1b both sides in described walling crib 1 are respectively equipped with brute spring 7.Well lid 2 is contained in walling crib 1 and after being locked by bayonet unit, brute spring 7 is in by the state compressed.Such design has two advantages: one is when vehicle is by well lid 2, and brute spring 7 can provide certain buffering, prevents well lid 2 to be crushed to death; Two is that brute spring 7 can provide certain thrust to help well lid 2 and open, and prevents the well lid 2 caused owing to being silted up by rubbish between well lid 2 and walling crib 1 to be difficult to open after well lid 2 unlocks.Described brute spring 7 preferably adopts antirust spring.

In the utility model, described well lid 2 preferably adopts rigid plastics to make.Fixture block 3 in described bayonet unit, cylindrical bars 4, hollow section 5 and handle 6 all preferably adopt metal material to make.
