Description
The utility model relates to a kind of anti-stealing manhole cover.
Road inspection shaft lid is widely used in the inspection well head that urban ducts such as telecommunications, power supply, water supply, blowdown are built, but metal inspection shaft lid is stolen easily.For antitheft, at present anti-stealing manhole covers that use more, existing anti-stealing manhole cover generally is made up of loam cake and base, and the edge of last lid and bottom connects by fixed hinge, to play antitheft effect.Because hinge position must be lower than ground, thereby loam cake can't set level when opening, and with angle at 45, ground about, after the constructor enters well head, and loam cake is collided, cover easily, more dangerous.In addition, when cable, pipeline are installed,, also can hinder construction, bring inconvenience if the direction that loam cake starts is improper.
The purpose of this utility model provides a kind of safe in utilization, does not influence the anti-stealing manhole cover of site operation.
The technical solution of the utility model is, this anti-stealing manhole cover comprises loam cake and base, it is characterized in that, loam cake and base edge connect by dual hinge structure, promptly between loam cake and base, connect a movable block, one end of this movable block is hinged by a fixed hinge and base, and the other end of movable block is hinged by a hinges and loam cake.
The utility model has the advantages that, when loam cake closes, whole loam cake and hinges are lower than the base upper port plane, and when loam cake starts, because the rotation of movable block makes hinges exceed the base upper port plane, thereby loam cake can open 180 °, keep flat on the ground, not only safe in utilization, and make the site operation of cable, pipeline easier for installation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 is the structural representation of the utility model when being in loam cake and closing;
Fig. 2 is the structural representation of the utility model when being in loam cake and opening.
As shown in Figure 1 and Figure 2, connect a movable block 3 between the loam cake 1 of this anti-stealing manhole cover and the base 2, an end of this movable block 3 is hinged by a fixed hinge 4 and base 2, and the other end of movable block 3 is hinged by a hinges 5 and loam cake 1.When loam cake closed, whole loam cake and hinges were lower than the base upper port plane, and when loam cake starts, can keep flat on the ground.
