Description
Technical field
The present invention relates to a kind of cable well lid, particularly a kind of anti-theft cable pit cover.
Background technology
The problem of cable shaft losing of cover exists for a long time, more anti-stealing manhole cover is also arranged at present, some anti-theft effect of these anti-stealing manhole covers is not good, the certain structures complexity is meticulous, manufacture difficulty, and long-term wind and weather easily rust is dead, all could not large-arealy promote the use of, and allows well lid lose this problem and all can't effectively solve always.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of can be effectively antitheft, simple in structure, and be difficult for the anti-theft cable pit cover lost efficacy because getting rusty.
To achieve these goals, the technical solution used in the present invention is:
A kind of anti-theft cable pit cover, comprise manhole cover base and well lid, on the edge of described well lid, annular is provided with at least 8 capable of regulating combination fasteners equably, on described well lid, corresponding capable of regulating combination fastener is provided with scale mark, described capable of regulating combination fastener comprises special shaped screw bolt, dop and lock pin, described special shaped screw bolt head is provided with bearing mark, described special shaped screw bolt afterbody is provided with the auxiliary section of prism-shaped, described auxiliary section end is provided with lockpin hole, described dop comprises the connecting portion of column type, described connecting portion one end is provided with the column type card of side inscribe with it, described card diameter is greater than the connecting portion diameter, described dop offers the through hole of corresponding matching section along the axis direction of connecting portion.
As preferred version of the present invention, described capable of regulating composite card number of packages amount is 8.
As preferred version of the present invention, described special shaped screw bolt head is equilateral triangle.
As preferred version of the present invention, described auxiliary section is four-prism.
As preferred version of the present invention, the fit clearance of described manhole cover base and well lid is 1 to 3mm, and the diameter of described connecting portion is 14 to 16mm, and the diameter of described card is 25 to 30mm.
Anti-theft cable pit cover of the present invention, only have when the card of capable of regulating combination fastener rotates to the angle tangent with manhole cover base just in opening, this well lid has 8 capable of regulating combination fasteners at least, be not difficult to confirm that whether single capable of regulating combination fastener is in opening in the situation that open well lid, and the prism fit structure of capable of regulating combination fastener, make capable of regulating combination fastener that N different shape be arranged, thereby the formed combinations of states of whole well lid has 8 powers of N at least, and open combination, can only be wherein a kind of, in the situation that do not know combination, very little of the probability that tries out unlatching combination in short time, there is good anti-theft capability.Anti-theft cable pit cover of the present invention, do not relate to complicated drive mechanism, and structure is simpler, not fragile.Anti-theft cable pit cover of the present invention, connecting portion intensity is high, and wedging position is little, even also can reverse by force capable of regulating combination fastener open manhole cover after getting rusty.
