Abstract
The utility model discloses a manhole cover burglar-proof mechanism which comprises a connection rod and a sealed sliding channel. The sealed sliding channel is fixed to the bottom face of a manhole cover. One end of the connection rod is hinged to the inner side end face of a base, and the other end of the connection rod is connected with the sliding channel. Displacement between the manhole cover and the base is limited by arranging the connection rod, so that the phenomenon that the manhole cover is stolen and lost is avoided. Meanwhile, by means of sliding matching between the connection rod and the sealed sliding channel, normal opening and closing of the manhole cover are ensured. The manhole cover burglar-proof mechanism is simple in structural design, convenient to use and flexible to operate, cannot cause any influences to the existing manhole cover and a base structure, is convenient to mount and use, greatly improves use safety and reliability of the manhole cover, avoids the phenomenon that the manhole cover is stolen, reduces maintenance cost, maintains social stability, and is suitable for being mounted, popularized and used on various manhole covers.
Description
Technical field
The utility model relates to a kind of mechanism, and particularly a kind of burglar-proof mechanism being connected between well lid and base, belongs to communal facility plumbing field.
Background technology
Well lid is a kind of common communal facility, is mainly laid on road or in public greening band, and be the most common a kind of parts in communal facility plumbing field, it is made by cast iron materials conventionally, and volume is large, heavy, has certain recovery value.
Existing well lid all directly covers on well head in use, does not have any safeguard measure, and anyone can move easily and move out.Because well lid is mainly used in public facility construction, its position focuses mostly on road and highway, quantity is many, distribute wide, simultaneously, casting iron well lid shock resistance is good, resistance to pressure is strong, long service life, there is certain economic worth, so, well lid is stolen, stolen phenomenon is very serious, often just there are dozens of or hundreds of well lids stolen in evening, make to occur on highway black hole one by one, not only affecting road normally uses, bring huge potential safety hazard also can to pedestrian and driving vehicle, even generation personnel fall or the security incident such as vehicle rollover, have a strong impact on normal social life, destroy social stability, to civil order, cause huge harmful effect.
So, to well lid, anti-theft device being set, should open conveniently, do not affect normal use, there is again anti-theft feature, guarantee well lid safety, with regard to becoming the utility model, want the problem solving.
Summary of the invention
In view of above-mentioned existing situation and deficiency, the utility model aims to provide and a kind ofly can effectively prevent that well lid is stolen, simple in structure, easy to connect, use manhole cover anti-theft mechanism flexibly, the safety and reliability using to improve well lid.
The utility model is achieved through the following technical solutions:
A manhole cover anti-theft mechanism, comprises a connecting rod and a sealing slideway, and sealing slideway is fixed on the bottom surface of well lid; Connecting rod one end is hinged on the inner side end of base, and the connecting rod other end is connected with slideway.
Sealing slideway comprises left and right two sealing chutes, and left and right two sealing chutes are relatively fixing, and connecting rod is plugged in left and right two sealing chutes by connecting axle.
Described connecting rod is tabular, and the longitudinal cross-section of tabular connecting rod is shaped as arc.
A kind of manhole cover anti-theft described in the utility model mechanism, by connecting rod being set between well lid and base, utilize connecting rod one end to be hinged on base, the other end is slidably connected in the sealing slideway on well lid, displacement between well lid and base is restricted, has prevented that well lid is stolen, Loss, simultaneously, by being slidably matched between connecting rod and sealing slideway, the normal opening and closing of well lid have been guaranteed.Total simplicity of design, easy to use, flexible operation, can not have any impact to existing well lid and bottom holder structure, be convenient to again install and use, greatly improved the safety and reliability that well lid is used, avoided the stolen phenomenon of well lid, reduced maintenance cost, safeguarded social stability, be adapted at installing and promoting the use of on various well lids.
Accompanying drawing explanation
Fig. 1 is use structure graph of the present utility model;
Fig. 2 is the structural representation of connecting rod described in the utility model.
The specific embodiment
Center of the present utility model is by a simple burglar-proof mechanism is set, and not affecting under the normal prerequisite of using of well lid, the moving range of well lid is limited, and prevents well lid loss, stolen.
Below in conjunction with accompanying drawing 1, Fig. 2, the utility model is described in further detail:
A kind of manhole cover anti-theft described in the utility model mechanism, comprises a connecting rod 7 and a sealing slideway.For guaranteeing connectivity robustness, connecting rod 7 be designed to one tabular, tabular connecting rod 7 has increased the stability of connecting rod 7, has guaranteed bonding strength.Sealing slideway comprises left and right two sealing chutes 3, left and right two sealing chutes 3 are fixed on the bottom surface of well lid 1 relatively, tabular connecting rod 7 one end are hinged on the inner side end of base 2, the other end is plugged in left and right two sealing chutes 3 of relative arrangement by connecting axle 5, forms the relative sliding of 3 of connecting rod 7 and left and right two sealing chutes.For guaranteeing well lid 1 flexible overturning, reduce the space that connecting rod 7 takies, the longitudinal cross-section shape of tabular connecting rod 7 has been designed to arc, and arc is conducive to the attended operation of connecting rod 7 and being free to slide in left and right two sealing chutes 3.
When the well lid 1 of burglar-proof mechanism described in the utility model being installed having been raised, be subject to the impact of tabular connecting rod 7, the rotation of rod hinge connection end, meanwhile, connecting rod 7 other ends slide in left and right two sealing chutes 3 by connecting axle 5, and well lid 1 is opened, but be subject to the restriction of connecting rod 7, well lid 1 is in outward-dipping or lying status, and well lid 1 can not be moved and leave, and has effectively prevented that well lid 1 is stolen.When closing well lid 1, well lid 1 falls, and by connecting axle 5, the far-end to left and right two sealing chutes 3 slides connecting rod 7, well lid 1 closure.Whole burglar-proof mechanism can not impact the normal use of well lid 1, and meanwhile, sealing sliding process and the state that is articulated and connected have effectively prevented the stolen phenomenon of well lid 1.
