Abstract
A multi-function tightening part for a plate on the vehicle against the thief, which relates to a means preventing from the bolt, the nut or the pin to be operated without allowed, specially relates to a tightening part mainly used for the plate on the motor-driven vehicle. The tightening part provides a reasonable structure a good multi-function one used on the steal-proof vehicle plate. The tightening part is equipped with the nut, the stud and the base. The edge of the nut along extend toward the inner is set at least with two pieces of the fixing claw and the top surface of the stud with a down Z model slot or a reverse Z model slot. Its upper and lower inside and outside and both flexible places are respectively finished with a anti-return slop. The centre of the base is fitted with the stud hole. The surround of the stud hole is set with the through hole coordinated with the fixing claw on the nut. For this purpose of the use, the stud goes through the center hole of the base and the fixing claw of the nut the through hole, thereby utilizing the elastic of the nut fixing claw to hold the stud and nut tightly at the lower surface of the base and to fix the vehicle plate correspondly.
Description
Technical field
The utility model relates to a kind of bolt that prevents, the measure of nut or pin unauthorized intervention especially relates to a kind of anti-theft fastening piece that is mainly used in automobile license plate.
Background technique
Various automobile license plates are stolen to be car owners' a big downer, brings a lot of inconvenience often for car owners and vehicle supervision department for this reason.Causing one of stolen easily reason of car plate is that existing its structure of car plate fastening piece is unreasonable, more existing for this reason automobile license plate burglary-resisting installations.
Notification number provides a kind of automobile license plate anti-theft device for the utility model patent of CN2346632, this device is to be provided with the window that manifests car plate on the member of Motor Vehicle installation car plate, the rotating carrier that the one side that is dragged through the gear speed regulator by direct current generator is equipped with car plate is equipped with in its inboard, direct current generator is provided with control device for reversing, rotating carrier is equipped with the mechanical position limitation parts of tape travel switch, and Motor Vehicle main switch may command rotating carrier is in car plate and manifests the position.
Notification number is that the utility model patent of CN2252271 discloses a kind of license-plate anti-theft bolt, license-plate anti-theft bolt screw part and nut are partly formed, bolt portion is made up of screw rod, screw head and screw fastener head, the nut part is made up of nut body and nut fastener head, screw head is round platform or billiard table shape, and by a cylindrical body link to each other with the screw fastener head formation one; Nut body is round platform or billiard table shape, and by a cylindrical body link to each other with the nut fastener head formation one; Two cylindrical diameters are 1/2～1/6 of screw diameter.Its shortcoming is when needs dismountings, when changing car plate, can cause certain damage to car plate etc.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, the multifunctional burglary-resistant car plate fastening piece that anti-theft feature is good at the irrational common problem of existing various car plate fastener constructions.
The utility model is provided with nut, screw rod and fixed base.The edge of nut has inwardly vertically extended at least 2 and has fixedly grabbed, and the tail end of fixedly grabbing preferably is provided with inside bending part.The screw head upper surface is provided with groove of falling the zigzag or reverse zigzag groove, inboard up and down at groove of falling the zigzag or reverse zigzag groove is provided with the anti-retrogression inclined-plane, two bending parts at groove of falling the zigzag or reverse zigzag groove are provided with the anti-retrogression inclined-plane respectively, preferably be provided with center hole on screw head, screw rod is preferably cored screw.The center of fixed base is provided with screw hole, is provided with fixed by nut around screw hole and grabs the through hole that matches.
Fixed by nut is grabbed and is preferably established 3～5.Upper surface at fixed base preferably is provided with groove, and groove is provided with packing ring, and packing ring is preferably spring washer; Lower surface at fixed base preferably is provided with tapped screw rod locking cap, is used for screw rod is locked in the car plate installation component.
During use, screw rod passes the fixed base center hole, nut fixedly grab the through hole that passes fixed base, utilize elasticity that fixed by nut grabs and by the lower surface of fastening, and corresponding car plate fixed at fixed base.When stealer will be dismantled car plate,, therefore be difficult to pull down nut at first because fixed by nut promptly is held in the fixed base lower surface; Secondly, even nut is removed, but owing to two bending parts that are provided with groove of falling the zigzag or reverse zigzag groove at the screw head upper surface are provided with the anti-retrogression inclined-plane respectively, therefore dismounting can't fall back screw rod, and more be firmly, more the groove of falling the zigzag or the reverse zigzag groove of screw head upper surface can be wrecked, more be difficult to dismantle down screw rod, really play the effect of anti-retrogression, finally realize antitheft function.When needs dismountings or when changing car plate, only need to adopt as instruments such as percussion drill are aimed at the screw head center hole and operated, can destroy by hollow screw rod, dismounting or change car plate easily, and can not damage the parts (for example bumper bar etc.) of car plate and installation car plate.
