Abstract

A well lid lock comprises a lock cylinder, a cross beam and a key. The well lid lock is characterized in that a lock body is in the shape of a disc box and comprises an upper cover, a lock body box and a lower cover, a protruded cap end of a bolt penetrates through a circle-center hole of the lock body and a cross beam center hole with the diameter equal to that of a wellhead, the other end of the bolt is fixed inside a cross beam groove via a screw cap, a lock bolt extends into the circle-center hole of the lock body and then extends to a protruded cap edge of the bolt to be clamped after being locked so that the lock bolt can not be withdrawn, a lock core and a shifting block are coaxially arranged inside a disc, a column connected with a lock bolt stopper is arranged in an electromagnet, the lock bolt stopper is placed in the periphery of the stopper, a self-locking piece and a spring are mounted beside the lock bolt stopper, a long end and a projection of the self-locking piece can be abutted with the shifting block and the stopper, an electric control device is arranged in another semicircle, consists of a unique code, a communication electronic part and a circuit board of the lock and is communicated with an external lock pick, after judgment is correct, the electromagnet acts to lead the bolt stopper to be withdrawn, and then the well lid lock is unlocked via a hexangular key rod. The well lid lock with an electronic lock adopts carrier communication system management, limits unlocking permission of unlocking personnel, records unlocking, strengthens industrial construction management, is simple in unlocking, adopts the cross beam as a lock nose when the lock body and a well lid are fixed, and has the advantages that the well lid lock is firm, and is difficult to be broken and applicable to various severe environments.

Description

A kind of pattern manhole cover lock

Technical field

The utility model relates to a kind of anti-theft device, particularly a kind of theftproof lock at the employed underground passage well of telecommunication facility well lids such as communication cable, optical cables.

Background technology

Present existing underground passage well well lid is made by cast iron usually, and the lawless person steals well lid for minor benefit, causes exposures such as communication cable, optical cable in the well, and is stolen easily, causes economic loss difficult to the appraisal for communication common carrier and users.Although present well lid is also established lock, be the standard machinery lock, open easily, easily destroyed, be difficult to management for the unlock staff in addition, promptly non-own job personnel also can open well lid, for management later on causes adverse consequences.Existing pattern manhole cover lock structure: its dead bolt bar is fixed on the walling crib, and two fixing holes are arranged on the walling crib, and the dead bolt bar must insert wherein fixing, and this opens to the user of service, closes and causes trouble, especially when north of china in winter, wastes time and energy more.

Summary of the invention

The purpose of this utility model provides a kind of pattern manhole cover lock, is the theftproof lock of underground passage well lid, and it is a kind of electronic lock, personnel's unlocking authority can be set, open simply, lock body and well lid are fixing to be the lock nose with the crossbeam, have firmly, difficult destruction adapts to the characteristics of various adverse circumstances.

A kind of pattern manhole cover lock, comprise tapered end, crossbeam, key is formed, it is characterized in that lock body is that disk is box-like, comprise loam cake, lock case, lower cover, the prominent cap end of bolt pass the lock body circle center hole and with the isometrical crossbeam centre bore of well head, in the crossbeam groove, the back dead bolt of locking stretches into the lock body circle center hole and blocks to the prominent shade of bolt the bolt other end, and it can not be withdrawed from by fixed by nut, lock core places in the dish with shifting block is coaxial, the cylinder that links to each other with the dead bolt block is in electromagnet, and the dead bolt block places in the shifting block circumference, adds spring from locking plate and is positioned on by the dead bolt block, self-locking length of a film end and bur can be conflicted with shifting block and block, automatically controlled device is in another semicircle, by the unique code of lock, communication soft copy and circuit board are formed, with external lockaid gun communication, behind the correct judgment, the electromagnet action is withdrawed from the dead bolt block, unblanks with six rib key bars again.

The design's lock body is a circular configuration, opens or closes all and need not adjust direction or angle.When unblanking, need soft copy to obtain unlocking signal, drive magnet coil earlier, arrangement of clutch inserts key bar the lockhole rotational lock core after starting again, realized unblanking by mechanical part, otherwise lock core can not rotate during singly with key bar.What the design adopted is the carrier communication system principle, not just to the protection of well lid, has more strengthened the security performance of terminal subject matter, simultaneously, defines the unlocking authority of unlocking person, strengthens the industry execution control, and places on record, uses safer.
