Description
Technical field:
The utility model relates to a kind of lockset, relates in particular to a kind of lockset that prevents that well lid from losing.
Background technology:
Fast development along with urban construction, various pipelines, the cable of many industries such as telecommunications, electric power, coal gas, municipal blowdown taked the mode of operation more and more with going into, therefore, how to make well lid not only can open easily, but also can prevent that well lid from losing and just become problem that becomes increasingly conspicuous in the urban construction.At present, though the well lid that is provided with anti-theft device has been adopted in the city that has, therefore defectives such as ubiquity complex structure, cumbersome, the antitheft poor reliability of unlatching and manufacturing cost height, easy corrosion are difficult to apply on a large scale.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aim to provide a kind of simple in structure, open well cover antitheft device convenient, antitheft good reliability.
To achieve these goals, the utility model by the following technical solutions: it is made of theftproof lock and retaining mechanism, and described theftproof lock comprises core print seat and lock core; Lock core is installed in the core print seat, and the poke rod that is located on the lock core passes from the hole of core print seat; At least be provided with two blind holes that spring and core print seat pellet shot from a slingshot are housed on the core print seat, the position corresponding to each described blind hole on the lock core is provided with through hole, and a part that is installed in the lock core marble in each described through hole is exposed in the keyhole that is arranged at the lock core end face; Described retaining mechanism by be fixed on cam on the poke rod, be fixed on the well lid back side support, be installed at least one latch on this support and the back-moving spring that is installed on this latch constitutes.
Keyhole is that cross sectional shape is triangle, quadrangle, pentagon, hexagon, ellipse, has a cavity of one of the circle of keyway or key; Top at core print seat is provided with seal cover, is provided with sealing ring between core print seat and the seal cover; It is triangle, quadrangle, pentagon, hexagon, ellipse that the end face of seal cover is provided with cross sectional shape, have the cavity of one of the circle of keyway or key, is provided with in this chamber and the suitable magnet of described cavity.
Compared with the prior art, the utility model has been installed principle and the essentially identical theftproof lock of traditional ball spring lock owing to covering at open well, and installed by cam and the common retaining mechanism that night bolt constituted at the back side of well lid, therefore when guaranteeing antitheft reliability, can make things convenient for the unlatching of well lid again; Owing to be provided with seal cover, therefore can prevent the lock core corrosion effectively and avoid keyhole to be stopped up by foreign matter.In addition, the utility model also have simple in structure, easy to operate, cost is low, be easy to advantage such as existing well lid transformation.
