Description
Technical field
It is specially a kind of unlatching easily anti-theft type inspection well cover the present invention relates to a kind of inspection well cover.
Background technology
Generally, mole drain and underground utilities passage are designed with inspection shaft, and are provided with inspection well cover in the inlet port of inspection shaft, for the inspection well cover being arranged on urban road and pavement, due to needing to bear substantial amounts of spreading, therefore, this kind of inspection well cover is made of the cast iron of resistance to spreading mostly.However, using castiron inspection well cover after installing and using, stolen phenomenon often occurs, serious potential safety hazard is brought to vehicle and the current of pedestrian.
For case above, in recent years, though the inspection well cover for having a variety of anti-theft types occurs, but it is most of all to employ coded lock and private key locking, well lid is fixed by hinge, chain or bolt connection, but in actual use, the problem of this kind of anti-theft type inspection well cover has complicated inconvenient for use, design and higher cost, meanwhile, the situation of blocking, corrosion also occurs in hinge, chain or bolt, is made troubles to unlatching maintenance in the future.
The content of the invention
To solve above-mentioned problem, the invention provides a kind of cost it is relatively low, open easily anti-theft type inspection well cover in the future.
The present invention concrete scheme be：One kind opens easily anti-theft type inspection well cover, with well seat and well lid, well seat madial wall is provided with the inner side edge of a protrusion, bar hole is provided with the side of inner side edge, the side of well lid bottom surface is provided with coupling bar, coupling bar is movably arranged in bar hole, and sprue is provided with the bottom of coupling bar, well lid is constituted movable, non-dismountable structure with well seat；The well lid, which is provided with groove through hole, groove through hole, is provided with L-shaped safety lock, and one end that L-shaped safety lock is located in groove is provided with tapered end, and L-shaped safety lock, which is located at the other end of well lid bottom surface, to be hooked on tapered end rotation on the downside of the inner side edge of well seat；Spring is also equipped between tapered end and groove through hole.
Well lid edge of the present invention has chimb, and chimb can be fastened on above well lid, makes to form closing space between well lid and well seat.
Corresponding up and down between tapered end of the present invention and groove through hole to be welded with limited bolt, the spring is fixedly mounted on limited bolt.
Osculum is provided with groove through hole of the present invention.
L-shaped safety lock of the present invention is made with spring of 304 stainless steels.
Compared with existing inspection well cover, the advantage that the present invention possesses is：
1. the inspection well cover opening structure coordinated using L-shaped safety lock with spring, and using the preferable stainless steel material manufacture of corrosion resistance, solve the problem of traditional inspection well cover causes maintenance difficult because opening structure rust is dead；
2. setting chimb at inspection well cover edge, the space position that can prevent rainwater, dust etc. from entering between well lid and well seat improves the service life of well lid.
Brief description of the drawings

Fig. 2 is well lid and well seat opening schematic diagram；
Fig. 3 is the enlarged diagram of L-shaped safety lock and well seat locking state；
Fig. 4 is L-shaped safety lock stereogram.
In figure, 1- well lids, 2- wells seat, 3- inner side edges, 4- bar holes, 5- coupling bars, 6- sprues, 7- groove through holes, 8-L shape safety locks, 9- tapered ends, 10- limited bolts, 11- springs, 12- chimbs, 13- osculums.
Embodiment
In the present embodiment, one kind opens easily anti-theft type inspection well cover, with well lid 1 and well seat 2, well 2 madial walls of seat are provided with the inner side edge 3 of a protrusion, bar hole 4 is provided with the side of inner side edge 3, the side of the bottom surface of well lid 1 is provided with coupling bar 5, and coupling bar 5 is movably arranged in bar hole 4, sprue 6 is provided with the bottom of coupling bar 5, well lid 1 is constituted movable, non-dismountable structure with well seat 2；
The groove through hole 7 with osculum 13 is provided with well lid 1, L-shaped safety lock 8 is installed in groove through hole 7, L-shaped safety lock 8 is located at tapered end 9 of the one end provided with special shapes such as knuckle-tooth shape or triangles in groove, and the other end that L-shaped safety lock 8 is located at the bottom surface of well lid 1 can rotate the downside of inner side edge 3 for being hooked on well seat with tapered end 9；It is corresponding up and down between tapered end 9 and groove through hole 7 to be welded with limited bolt 10, the spring 11 that can pop up L-shaped safety lock 8 is installed on limited bolt 10；
Chimb 12 is additionally provided with the edge of well lid 1, when well lid 1 and well 2 closure of seat, chimb 12 can be fastened on the top of well lid 1, make to form confined space between well lid 1 and well seat 2, prevent rainwater and debris from entering, in addition, L-shaped safety lock 8 is made with spring 11 of corrosion resistant 304 stainless steel.
The present invention operation principle be：When needing to open well lid 1, using in the special sleeve spanner insertion tapered end 9 supporting with tapered end 9, rotate L-shaped safety lock 8, deviate the inner side edge 3 that well seat 2 is hooked in the one end for making L-shaped safety lock 8 be located at the lower section of well lid 1, and in the presence of spring 11, L-shaped safety lock 8 is upspring from groove through hole 7, now, in the presence of external force lifting, the coupling bar 5 of the bottom surface of well lid 1 is extracted out from the bar hole 4 in well 2 inner side edges 3 of seat, because the length of bar hole 4 is more than the width of coupling bar 5, sprue 6 it is spacing under, well lid 1 just can be at a certain angle opening angle realize the unlatching of non-dismountable formula on well seat 2；
When needing to lock well lid 1 and well seat 2, well lid 1 is fastened on well seat 2 first, reuse in the special sleeve spanner insertion tapered end 9 supporting with tapered end 9, by pressing spring under external force 11, L-shaped safety lock 8 is set to be located at inner side edge 3 of the one end less than well seat 2 of the lower section of well lid 1, L-shaped safety lock 8 is rotated by special sleeve spanner, the inner side edge 3 for hooking L-shaped safety lock 8, so as to realize the locking of well lid and 1 well seat 2.
