A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

Please refer to fig. 1 and 2, an anti-theft well lid, including well lid body 1, screw rod 2, movable rod 3 and vaulting pole 4, well lid body 1 middle part is provided with first through-hole, screw rod 2 upper end is provided with wrench movement head 21, 2 upper portions of screw rod rotate and install in first through-hole, movable rod 3 is located well lid body 1 below, 2 lower extremes of screw rod rotate with movable rod 3 to be connected, the tip of movable rod 3 is provided with spacing hole 31, vaulting pole 4 lower part is worn to establish in spacing hole 31, vaulting pole 4 upper end is articulated with well lid body 1 lower terminal surface. Specifically, spacing hole 31 adopts the reinforcing bar to buckle the preparation, and the reinforcing bar both ends and 3 end fixing of carriage release lever, the intra-annular space that reinforcing bar and carriage release lever 3 enclose forms spacing hole 31. The outer wall of the twisting head 21 of this embodiment is a regular hexagon structure, and the up end of the twisting head 21 is provided with a regular hexagon's shrinkage pool, and the twisting head 21 can use monkey wrench or allen key to twist like this.

In this embodiment, the number of the stay bars 4 is two, and the two stay bars 4 are symmetrically arranged with respect to the screw 2. The well lid body 1 comprises a cover plate 11 and a mounting rod 12, the mounting rod 12 is arranged on the lower end face of the cover plate 11, a first through hole is formed in the mounting rod 12, and the screw rod 2 is rotatably connected with the mounting rod 12; the cover plate 11 is provided with a yielding hole 14, and the twisting head 21 is positioned in the yielding hole 14. The mounting rod 12 is made of a square tube, a bushing 13 is arranged in the first through hole, and the upper portion of the screw rod 2 is rotatably connected with the bushing 13. The lower end of the mounting rod 12 is provided with two convex columns 15, and the upper end of a stay bar 4 is hinged with one convex column 15. Through the vaulting pole 4 that the symmetry set up, can make 1 symmetry atress of well lid body, the whole well lid of being convenient for is fixed. The mounting rod 12 and the moving rod 3 are made of square materials, and the material source is simple and convenient, and the cost is low. Can prevent through being provided with bush 13 that screw rod 2 and installation pole 12's rotation is more smooth and easy, bush 13 can be to the better spacing of screw rod 2 simultaneously, prevents the swing of screw rod 2.

In this embodiment, the movable rod 3 is made of a square tube, a second through hole is formed in the middle of the square tube, a first nut 32 coaxial with the second through hole is fixed on the movable rod 3, and the screw rod 2 penetrates through the second through hole and is in threaded connection with the first nut 32. Be provided with spacing ring 22 on the screw rod 2, the up end of spacing ring 22 offsets with the lower terminal surface of well lid body 1. Specifically, the retainer ring 22 is made of a nut, which is screwed onto the screw rod 2, and the nut and the screw rod 2 are fixedly connected by welding after being rotated to a proper position. Through seting up the hole of stepping down 14 on apron 11, make the head 21 of wrench movement adorn in the hole of stepping down 14, the level of the up end of whole well lid like this can not influence pedestrian's walking and vehicle and travel.

During the use, cover whole device on the well head, use specialized tool to pull screw rod 2, when screw rod 2 rotated, movable rod 3 can only reciprocate owing to vaulting pole 4's limiting displacement, and when movable rod 3 upwards moved, movable rod 3 pushed away the centraxonial direction of screw rod 2 with vaulting pole 4's lower extreme orientation, when vaulting pole 4's lower extreme and well body inner wall offset, accomplished the fixed mounting of whole well lid. When wanting to open the well lid, need the specialized tool to twist reverse screw rod 2, make carriage release lever 3 downstream, the removal of carriage release lever 3 makes the lower extreme and the well body inner wall separation of vaulting pole 4, and the well lid can be opened the well lid. Based on the above, the well lid installation back because the lower extreme and the well body inner wall of vaulting pole 4 offset, the personnel that do not have the specialized tool want to pull up and open the well lid be difficult, has realized the theftproof effect of well lid. The manhole cover solves the technical problems that a traditional manhole cover is easy to steal, so that a well hole is directly exposed on the ground, and pedestrians and vehicles are easily injured when passing through the manhole cover.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
