Abstract
The utility model discloses a kind of anti-stealing manhole cover, relate to manhole cover anti-theft technical field.The circle centre position rotating shaft of well lid body lower surface is connected with gear; Two slide rails that be arranged in parallel are installed taking the center of circle, well lid body lower surface as symmetrical centre; In each slide rail, all slidably connect the tooth bar engaging with gear; Well lid body lower surface is also provided with lockset; The dead bolt of lockset coordinates with tooth bar clamping; The lockhole of lockset is arranged at the upper surface of well lid body.The beneficial effects of the utility model are: slide rail and tooth bar are slidably connected, and realize the counter motion of two tooth bars by transmitting gear, and two tooth bars and well lid pedestal have enough inserting depths, and by lockset, tooth bar are locked, simple in structure, and it is convenient to control.
Description
Technical field
The utility model relates to manhole cover anti-theft technical field.
Background technology
At present, along with the area coverage of Chinese transportation road is more and more wider, the manhole of using also increases sharply thereupon, the requirement of well lid is also increased to some extent, modal phenomenon is exactly that well lid is stolen, has caused the harm of public safety, brings about great losses also to national human and material resources and financial resources.
Existing well lid lacks anti-theft technique, often, because stolen and bring potential safety hazard to traffic, brings very big harm to the productive life of numerous people.
Utility model content
Technical problem to be solved in the utility model, it is the technical deficiency for above-mentioned existence, a kind of anti-stealing manhole cover is provided, slide rail and tooth bar are slidably connected, realize the counter motion of two tooth bars by transmitting gear, two tooth bars and well lid pedestal have enough inserting depths, and by lockset, tooth bar are locked, simple in structure, control conveniently and can well solve the stolen problem of well lid.
The technical solution adopted in the utility model is: anti-stealing manhole cover, and the circle centre position rotating shaft of well lid body lower surface is connected with gear; Two slide rails that be arranged in parallel are installed taking the center of circle, well lid body lower surface as symmetrical centre; In each slide rail, all slidably connect the tooth bar engaging with gear; Well lid body lower surface is also provided with lockset; The dead bolt of lockset coordinates with tooth bar clamping; The lockhole of lockset is arranged at the upper surface of well lid body.
Further optimize the technical program, the upper end of the gear shaft of the gear of anti-stealing manhole cover is through the upper surface of well lid body, and the upper surface of gear shaft has the triangular prism shape groove of vertical direction.
Further optimize the technical program, the upper surface of the well lid body of anti-stealing manhole cover is evenly distributed with multiple through holes.
The beneficial effects of the utility model are: 1, slide rail and tooth bar are slidably connected, and realize the counter motion of two tooth bars by transmitting gear, and two tooth bars and well lid pedestal have enough inserting depths, and by lockset, tooth bar are locked, simple in structure, and it is convenient to control.2, remain basically stable in the upper surface of the lockhole of lockset and the upper end of gear shaft and well lid body, makes the utility model flat appearance, can not affect well lid result of use, and safety is attractive in appearance and practical.
Brief description of the drawings
Fig. 1 is the schematic diagram of a direction of the utility model;
Fig. 2 is the structural representation of another direction of Fig. 2.
In figure, 1, well lid body; 2, gear shaft; 3, gear; 4, slide rail; 5, tooth bar; 6, lockset; 7, dead bolt; 8, well lid pedestal; 9, triangular prism shape groove; 10, through hole; 11, lockhole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, anti-stealing manhole cover, the 1 lower surface circle centre position rotating shaft of well lid body is connected with gear 3; Taking well lid body 1 center of circle, lower surface as symmetrical centre, two slide rails that be arranged in parallel 4 are installed; The interior tooth bar 5 engaging with gear 3 that all slidably connects of each slide rail 4; Well lid body 1 lower surface is also provided with lockset 6; The dead bolt 7 of lockset 6 coordinates with tooth bar 5 clampings; The lockhole 11 of lockset 6 is arranged at the upper surface of well lid body 1; The upper end of the gear shaft 2 of gear 3 is through the upper surface of well lid body 1, and the upper surface of gear shaft 2 has the triangular prism shape groove 9 of vertical direction; The upper surface of well lid body 1 is evenly distributed with multiple through holes 10.
Staff can insert triangular prism shape groove 9 by interior triangle spanner, carrys out turning gear wheel shaft 2 tooth bar 5 is moved back and forth, thereby make tooth bar 5 peg graft or separate with well lid pedestal 8.Two tooth bars 5 are at the two ends of 1 one diameters of well lid body, itself and well lid pedestal 8 to be pegged graft substantially, stressed even.
The dead bolt 7 of lockset 6 directly acts on a tooth bar 5, plays the effect of two tooth bars 5 of locking.
