Description
Technical field
A kind of license-plate anti-theft screw relates to fixedly screw rod, the nut external member of sedan car car plate.
Background technique
Screw rod, nut are a kind of general connection fastening pieces, and it is promptly convenient, reliable again to use.But under some special situations, just showed its deficiency, as antitheft.It links up conveniently, removes also very convenient.
The model utility content
The purpose of this utility model provides a kind of screw rod, nut assembly that prevents illegal dismounting.
This license-plate anti-theft screw is made of screw rod, nut and pad; Have a skewed slot on screw rod, skewed slot has shoulder hole from deep to shallow in the skewed slot, spring and pull bar are housed in the hole, the locking plate of arc also is housed in the skewed slot, the upper end of locking plate and spring and pull bar links, lock core is housed in the screw rod, a cam is arranged on the lock core, link with the lower end of pull bar; Front portion at screw rod has keyway, and the locked key of interior loading screw also is equipped with car plate card key on this key, and the thickness of car plate card key is greater than the thickness of car plate; The end face of pad has a breach, in order to be stuck on the car plate card key; Have a draw-in groove in the hole of nut, be used for snapclose sheet.
During use, earlier screw rod is screwed in the box of entrucking board on the car, load onto locked key of screw rod and car plate card key, rotating screw bolt makes car plate card key be horizontal, load onto car plate, make its slotted hole be stuck in (at this moment, screw rod just can't rotate) on the car plate card key, load onto pad then, again nut is screwed on the screw rod, simultaneously locking plate is pressed in the skewed slot.When the middle part of nut was screwed into the position of locking plate, under the effect of spring, locking plate headed in the interior draw-in groove of nut bore, and nut is promptly locked.As will opening by force, locking plate certain distance of can sliding in skewed slot promptly slides into shallow place, and nut is locked fully.As think normally to open nut, and only need key is inserted the lock core rotation, by pull bar locking plate is withdrawn into the skewed slot in the draw-in groove of nut, promptly available spanner is unloaded nut down.The screw of unloading down is also reusable.This anti-theft screw can't be opened with general spanner after installing, and it can prevent effectively that the car car plate is stolen.
