Abstract
The utility model relates to a kind of anti-stealing manhole cover, and the manhole cover body comprising well seat and coordinate with well seat, also comprises the bar magnet that can open and close magnetic force; Described manhole cover body is provided with vertical through holes and cross through hole, and described vertical through holes is located at the middle part of manhole cover body, and cross through hole is located between well seat and vertical through holes; Described well seat is provided with the well bore corresponding with cross through hole, is provided with the magnetic patch that magnetic is less than described bar magnet magnetic, is provided with locking bearing pin in described cross through hole in well bore, and described locking pin slide is in cross through hole and well bore.The utility model structure is simple, opens and closes convenient and swift.
Description
Technical field
The utility model relates to urban infrastructure field, specifically a kind of anti-stealing manhole cover.
Background technology
In Municipal facility, the conveyance conduit of underground, pipeline all leave well head with convenient for maintaining, well head place is provided with well seat and well lid sealing, but the well lid of irony is often easily stolen at present, as plastic material be then be unable to undergo that road gets on the bus roll and destroyed, bring potential safety hazard to pedestrian and vehicle.Although the device being provided with locking had in existing well lid, structure is comparatively complicated, opens and closes and all comparatively bothers.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of structure simple, open and close conveniently anti-stealing manhole cover.
The technical scheme that the utility model adopts is: provide a kind of anti-stealing manhole cover, and the manhole cover body comprising well seat and coordinate with well seat, also comprises the bar magnet that can open and close magnetic force; Described manhole cover body is provided with vertical through holes and cross through hole, and described vertical through holes is located at the middle part of manhole cover body, and cross through hole is located between well seat and vertical through holes; Described well seat is provided with the well bore corresponding with cross through hole, is provided with the magnetic patch that magnetic is less than described bar magnet magnetic, is provided with locking bearing pin in described cross through hole in well bore, and described locking pin slide is in cross through hole and well bore.
After adopting above structure, the utility model anti-stealing manhole cover can insert in vertical through holes by bar magnet, locking bearing pin is skidded off well bore, remove the locking state of well lid, when the magnetic of bar magnet is eliminated, under the suction of magnetic patch, again slide in well bore, reach the object of locking, the utility model vibrational power flow is simple, opens and closes convenient and swift.
As preferably, described cross through hole is set to two, and symmetry is located at the both sides of vertical through holes, arranges two cross through hole, can strengthen the locking tightness of well lid.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model anti-stealing manhole cover.
In figure, 1, well seat, 2, manhole cover body, 3, bar magnet, 4, well bore, 5, cross through hole, 6, locking bearing pin, 7, magnetic patch.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model anti-stealing manhole cover, the manhole cover body 2 comprising well seat 1 and coordinate with well seat 1, also comprise the bar magnet 3 that can open and close magnetic force, manhole cover body 2 is provided with vertical through holes and cross through hole 5, vertical through holes is located at the middle part of manhole cover body 2, run through the thickness of manhole cover body 2, cross through hole 5 is located between well seat 1 and vertical through holes, namely cross through hole 5 one end is communicated with vertical through holes, well seat 1 is provided with the well bore 4 corresponding with cross through hole 5, namely the other end of cross through hole 5 is communicated with well bore 4, the magnetic patch 7 that magnetic is less than bar magnet 3 magnetic is provided with in well bore 4, locking bearing pin 6 is provided with in cross through hole 5, locking bearing pin 6 slides in cross through hole 5 and well bore 4.
In the specific implementation, cross through hole 5 is set to two to the utility model, and symmetry is located at the both sides of vertical through holes, also can be located at two or more, manhole cover body 2 chain can be connected on well seat 1, prevents from losing during maintenance.
Bar magnet 3 in use, inserts in vertical through holes by the utility model, opens its magnetic, because magnetic is greater than the magnetic of the magnetic patch 7 be located in well bore 4, locking bearing pin 6 holds by bar magnet 3, and manhole cover body 2 is unlocked, when closing the magnetic of bar magnet 3, locking bearing pin 6 is sucked back under the suction of magnetic patch 7, manhole cover body 2 is lockable, the utility model good anti-theft effect, and safety is higher, structure is simple, opens and closes convenient and swift.
