Abstract
An anti-theft steel fiber well cover relates to municipal public utilities. According to the design scheme provided by the anti-theft steel fiber well cover of the utility model, a support bar is arranged at the edge of one side of the well cover, characterized in that the well cover edge is further provided with at least one through hole for installing screw bolt, and the diameter of the upper portion of the through hole is larger than that of the lower portion. A step is formed in the through hole for avoiding the screw bolt dropping, and the head of the screw bolt has the shape of pentagon, or heptagon, or enneagon, which further enhances the anti-theft performance and security of the well cover.
Description
Technical field
The utility model relates to public utility, specifically a kind of concrete manhole cover.
Background technology
Concrete manhole cover mainly is applicable to occasions such as power supply, street lamp, post and telecommunications, water supply, avoids damage to protect these facilities.When needs maintenance is embedded in underground related facility, concrete manhole cover can be opened, so that entering underground passage, the maintainer overhauls, then well lid should built at ordinary times, in order to avoid the pedestrian falls, and guarantee the cruising of various vehicles.Existing well lid is not owing to there is good theftproof performance, and stolen phenomenon is very serious, and therefore causes various contingencies.Some steel fibre well lid also can send certain sound in vehicle traveling process in addition, produces noise.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-theft type well lid, with the theftproof performance of further raising concrete manhole cover, and security performance.
According to design scheme provided by the utility model, lateral edges at well lid is provided with pole, it is characterized in that: the edge at well lid also is provided with the through hole that at least one is used for erection bolt, the upper diameter of this through hole is greater than lower diameter, form one and be used to the step of avoiding bolt to drop in through hole, the head of this bolt is 5 dihedrals or seven dihedral or nine dihedral.
Inwall at through hole has one deck to play the quoit of booster action.Outer wall at well lid is provided with the quoit that one deck plays booster action.Extend downwards at the middle part, lower end of well lid, forms a protuberance.Concrete manhole cover is positioned at the concrete well seat, position corresponding to pole on the concrete well seat is provided with the pole hole of being convenient to the pole insertion, Connection Block is installed at position corresponding to through hole on the concrete well seat, and the screwed hole that can cooperate with bolt is set on Connection Block.
Junction plate is installed on Connection Block, the connecting rod vertical with junction plate is installed on junction plate, this connecting rod is embedded in the concrete well seat.On connecting rod, crotch is arranged near an end that is embedded in the concrete well seat.
The utility model has the advantages that: because used bolt is the bolt that off-gauge head is 5 dihedrals or seven dihedral or nine dihedral, when needs are opened, can only utilize special tool, can not operate with general utility tool, thereby play certain antitheft effect.

The specific embodiment
As shown in the figure: the lateral edges at well lid 1 is provided with pole 3, at the edge of well lid 1 at least one through hole that is used for erection bolt 46 is set also, the upper diameter of this through hole 6 is greater than lower diameter, form one and be used to the step of avoiding bolt 4 to drop in through hole 6, the head of this bolt 4 is 5 dihedrals or seven dihedral or nine dihedral.Inwall at through hole 6 has one deck to play the quoit 7 of booster action.Outer wall at well lid 1 is provided with the quoit 9 that one deck plays booster action.Extend downwards at the middle part, lower end of well lid 1, forms a protuberance 11, to improve the intensity of well lid 1.
Well lid 1 can be by concrete or composite material or metal making.Well lid 1 is positioned at concrete well seat 2, position corresponding to pole 3 on concrete well seat 2 is provided with the pole hole 12 of being convenient to pole 3 insertions, Connection Block 5 is installed at position corresponding to through hole 6 on concrete well seat 2, and the screwed hole that can cooperate with bolt 4 is set on Connection Block 5.Junction plate 8 is installed on Connection Block 5, the connecting rod 10 vertical with junction plate 8 is installed on junction plate 8, this connecting rod 10 is embedded in the concrete well seat 2, and during installation, the plane of this junction plate 8 is fitted in the inwall of concrete well seat 2.On connecting rod 10, crotch is arranged, to improve the adhesion of 2 of connecting rod 10 and concrete well seats near an end that is embedded in concrete well seat 2.The upper height of through hole 6 is equal to or greater than the height that is installed on bolt 4 heads in it, bolt 4 is installed again after, can not exceed the last plane of well lid 1, maintenance road surface smooth.
During use, pole on the well lid 13 is inserted in the pole hole of concrete well seat 2, well lid 1 is placed on the concrete well seat 2 reposefully, again seven corner bolt 4 is inserted in the through hole 6, this seven corner bolt 4 is screwed in the screwed hole on the Connection Block 5 that is arranged at concrete well seat 2 inwalls with the instrument of special use, well lid 1 is fixed on the concrete well seat 2.When needs are opened well lid 1,, well lid 1 is opened with special tool seven corner bolt 4 of outwarding winding.
Because of the field of conjugate action of heptangle taper anti-theft bolt and special tool is bigger, be not easy to skid, the scope of use is little, and special tool is controlled easily, and theftproof performance does not influence the surface aesthetic and the intensity of well lid.Therefore this anti-stealing manhole cover has better use promotion prospect.
