Abstract
The invention relates to a nondetachable anti-theft bolt device and an anti-theft method. In china, the losses of public facilities and properties and personal safety caused by the looseness of the junctions of mechanical components or artificial burglary and destroy can reach hundreds of millions of yuan every year and brings lots of effect for the healthy operation of national economy. The nondetachable anti-theft bolt device comprises a locking screw (1), a locking nut (3) and a locking gasket (6), wherein a slide (2) is formed in a threaded rod of the locking screw, and a locking groove (4) is formed in the locking nut; a group of locking lugs (5) is arranged on the inner wall of the locking groove; a fixing end (7) is arranged at one end of the locking gasket, and a resistance end (8) is arranged at the other end of the locking gasket; the locking gasket is inlaid in the locking groove of the locking nut, and the locking screw is assembled in the locking nut.
Description
technical field:
the present invention relates to a kind of non-dismountable formula antitheft bolt device and theft preventing method.
background technique:
china because mechanical component joint loosens or artificial theft destruction causes communal facility property and personal safety loss can reach more than more than one hundred million unit, runs to the health of national economy and brings very large impact every year.Such as, after the bolt of electric power system electric power pylon is backed out by thief, a part of Steel Support of steel tower is extracted out, collapse after causing steel tower to meet high wind or vibrations, cause serious consequence.
summary of the invention:
the object of this invention is to provide a kind of non-dismountable formula antitheft bolt device and theft preventing method.
above-mentioned object is realized by following technological scheme:
a kind of non-dismountable formula antitheft bolt device, its composition comprises: locking screws, lock nut, locking pad, the screw rod of described locking screws has slideway, described lock nut has latch groove, described latch groove inwall has one group of latch projection, one end on described locking pad has fixed end, the described locking pad the other end has resistance end, inlay locking pad in the latch groove of described lock nut, described locking screws is assembled in lock nut.
described non-dismountable formula antitheft bolt device, fixed end and the sliding into of locking screws of described locking pad match, and the resistance end of described locking pad fixes in the latch projection of latch groove inwall.
the theft preventing method of described non-dismountable formula antitheft bolt device, when tighten add fixing bolt time: the slideway fixed end of locking pad being put into locking screws, by the latch groove of lock nut towards locking pad direction, lock nut clockwise direction is screwed into locking screws; When lock nut is screwed to bottom locking screws, after fixture encountered by locking pad, fall into the latch groove into lock nut; Fixed end due to locking pad is fixed in locking screws slideway, so locking pad does not rotate with lock nut, and the resistance end of locking pad under spring force, when encountering the locking projection in latch groove, can takeoff, not affect lock nut clockwise direction and rotate; When lock nut touch fixture fastening after, locking pad is just embedded in the latch groove of lock nut completely; Anti-theft bolt completes the process being fastened and fixed thing; When wanting demounting bolt: to lock nut be unloaded from locking screws, lock nut need be rotated counterclockwise; Locking in the latch groove of now lock nut is protruding, will encounter the resistance end of locking pad; Fixed end due to locking pad is fixed in locking screws slideway, so locking pad does not rotate with lock nut, the resistance end of locking pad will hinder the protruding counterclockwise movement of locking, thus lock nut cannot be rotated counterclockwise unload from locking screws, simultaneously because locking pad is embedded in latch groove, so with any tool and method unlocking pad to the obstruction of locking projection, thus the object of anti-theft bolt Anti-dismantling cannot be reached from outside.
beneficial effect:
1. the invention solves this problem, after this anti-theft bolt is mounted, any instrument all cannot remove, the spanner that such as thief is usual, bottle opener, box spanner etc., and only have destructive instrument it could be removed, destructive instrument comprises: gas welding, file, iron hammer etc.
the present invention is novel in design, science is suitable for, and has the advantages that structure is simple, safe and reliable.Be applicable to shake machinery or facility that comparatively large and field is not easy to manage.As the sleeper of railway and the joint of rail, the power transmission and transformation pylon of oil field particularly power department, easily stolen, split, destroyed permanent outdoor building facility.
the present invention, to lock nut be unloaded from locking screws, need be rotated counterclockwise lock nut; Locking in the latch groove of now lock nut is protruding, will encounter the resistance end of locking pad; Fixed end due to locking pad is fixed in locking screws slideway, so locking pad does not rotate with lock nut, the resistance end of locking pad will hinder the protruding counterclockwise movement of locking, thus lock nut cannot be rotated counterclockwise unload from locking screws, simultaneously because locking pad is embedded in latch groove, so with any tool and method unlocking pad to the obstruction of locking projection, thus the object of anti-theft bolt Anti-dismantling cannot be reached from outside.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 locking screws structural drawing of the present invention.
accompanying drawing 3 is lock nut structural drawing of the present invention.
accompanying drawing 4 is locking gasket construction figure of the present invention.
embodiment:
embodiment 1:
a kind of non-dismountable formula antitheft bolt device, its composition comprises: locking screws 1, lock nut 3, locking pad 6, the screw rod of described locking screws has slideway 2, described lock nut has latch groove 4, described latch groove inwall has one group of latch projection 5, one end on described locking pad has fixed end 7, the described locking pad the other end has resistance end 8, inlay locking pad in the latch groove of described lock nut, described locking screws is assembled in lock nut.
embodiment 2:
non-dismountable formula antitheft bolt device according to embodiment 1, fixed end and the sliding into of locking screws of described locking pad match, and the resistance end of described locking pad fixes in the latch projection of latch groove inwall.
embodiment 3:
the theft preventing method of the non-dismountable formula antitheft bolt device according to embodiment 1 or 2, when tighten add fixing bolt time: the slideway fixed end of locking pad being put into locking screws, by the latch groove of lock nut towards locking pad direction, lock nut clockwise direction is screwed into locking screws; When lock nut is screwed to bottom locking screws, after fixture encountered by locking pad, fall into the latch groove into lock nut; Fixed end due to locking pad is fixed in locking screws slideway, so locking pad does not rotate with lock nut, and the resistance end of locking pad under spring force, when encountering the locking projection in latch groove, can takeoff, not affect lock nut clockwise direction and rotate; When lock nut touch fixture fastening after, locking pad is just embedded in the latch groove of lock nut completely; Anti-theft bolt completes the process being fastened and fixed thing; When wanting demounting bolt: to lock nut be unloaded from locking screws, lock nut need be rotated counterclockwise; Locking in the latch groove of now lock nut is protruding, will encounter the resistance end of locking pad; Fixed end due to locking pad is fixed in locking screws slideway, so locking pad does not rotate with lock nut, the resistance end of locking pad will hinder the protruding counterclockwise movement of locking, thus lock nut cannot be rotated counterclockwise unload from locking screws, simultaneously because locking pad is embedded in latch groove, so with any tool and method unlocking pad to the obstruction of locking projection, thus the object of anti-theft bolt Anti-dismantling cannot be reached from outside.
