One, the snap ring of hook lock device employing along the circumferential direction arranges lockholes a plurality of and the lock pin coupling on the snap ring side periphery.Along the circumferential direction process relatively difficulty of lockhole on snap ring side periphery, be difficult for processing, crudy is difficult to obtain assurance.
Two, the lock pin of hook lock device is the interior angle screw, just can open with the triangular key that railway is general, can't be antitheft, the stolen situation of hook lock device often occurs.
Three, interior angle screw and lockpin sleeve threaded engagement, along with the increase of access times, in addition train by the time strenuous vibration that produces can accelerate the damage of screw thread, hook lock device can't normally be used.
The utility model content
The problem that the utility model exists for existing hook lock device is movablely scolded from tongue with the antitheft hook lock device of track switch and provide a kind of, have antitheft, be easy to process, reliable in quality, characteristics easy to use.
The utility model is to address the above problem the technical scheme that adopts to be:
A kind ofly movablely scold from tongue with track switch antitheft hook lock device, the nut that comprises stay hook, the screw rod that is connected with stay hook, is enclosed within movable hook on the screw rod, between stay hook and movable hook, cooperates with screw flight, being provided with one between nut and the movable hook is enclosed within on the screw rod and the lock collar that is fixedly connected with nut, it is characterized in that: described lock collar circumference is provided with the lockhole of a plurality of axial directions, disposes the keyhole adaptive with lockhole on the described movable hook.
Further, described keyhole be located on the movable hook or be located at otic placode that movable hook is connected on.
Further, described otic placode is connected with movable hook by welding, riveted joint or bolt.
Further, be provided with draw-in groove on the described screw rod, be provided with the bayonet lock that cooperates with draw-in groove in the movable hook, movable hook cooperates with screw rod through bayonet lock, draw-in groove.
Further, described stay hook and screw rod are flexibly connected or are connected as a single entity.
Further, the grab direction on described stay hook and the movable hook arranges, and it is inboard to be stuck in stock rail and tongue.
Preferably, described screw rod is made as handle with respect to the stay hook end side.
Using method of the present utility model is:
During use, hook lock device is passed from stock rail bottom, an end (stay hook) withstands on the tongue waist, and the other end (movable hook) is stuck in edge, stock rail base, and then fastening nut aligns keyhole and lockhole position, locks padlock and namely finishes and lock.Open padlock during release, unclamp nut and can take off the withdrawal hook lock device.
Compared with prior art, the utlity model has following beneficial effect:
One, lock collar of the present utility model, lockhole is arranged on the lock collar axial direction, is easy to processing and guarantees crudy.
Two, the utility model uses padlock can finish the process of locking, and needs special-purpose key just can open when unblanking, and has good anti-theft feature.
