Description
Technical field
The utility model relates to the device that a kind of fastening or fixed component or machine parts are used, particularly a kind of antitheft securing means.
Technical background
Fastening or the fixed component of prior art or the device that machine parts is used generally all are to adopt devices such as screw, bolt to fix.For example Automobile registration is fixing, usually adopt common screw link to be fixed on the car plate pallet, it can take off car plate easily by instruments such as common spanner or screw-drivers, and some undesirables usually steal to sell off behind the car plate and obtain interests, or carry out illegal activity, bring infringement to the car owner; More for example be installed on outdoor implements again,, then also can steal easily, cause damage, make troubles also for the maintenance of civil order to public interests by instruments such as common spanner or screw-drivers if adopt common screw.
Summary of the invention
It is a kind of simple in structure, easy for installation that technical problem to be solved in the utility model is to provide, the antitheft securing means that Safety performance is good.
The utility model is realized by following approach.
Antitheft securing means, comprise screw bolt and nut, bolt has bolt head and bolt shank, its structure outline is: bolt is a kind of unidirectional bolt, the top of the bolt head of this bolt has a pair of projection, projection is staggered front to back distribution at the bolt head top, this projection has two facades with the bolt shank parallel axes, be respectively first facade and second facade, first facade is vertical with second facade, and first facade of two symmetry projectioies is relative, and is vertical facade, second facade of two symmetry projectioies is relative, and this second facade is for to seamlessly transit with bolt head.
Like this, top at bolt head, the first vertical relative facade of a pair of symmetry projection just forms a kind of 1/2nd the straight groove at bolt head top, contact with first facade of two projectioies respectively by the front-end and back-end of revolving a cutter, thereby the power of borrowing screws bolt, and since second facade of projection for to seamlessly transit with the bolt head plane, thereby do not make that because of there being the bayonet socket power of borrowing to skid screw-driver can't counterrotating during the screw-driver derotation.Therefore, when tighting a bolt by screw-driver, only import but no export is a permanent fixation after tightening, and can not dismantle, have simple in structure, the effect that Safety performance easy for installation is good.Need permanent fixation for some, prevent that the implements that are disassembled have antitheft function, particularly have antitheft effect for Automobile registration, make the motor vehicle number plate be not easy to lose, also make the car owner can't dismantle car plate privately, car plate is hitched other vehicle use, be convenient to the car pipe.
Structure of the present utility model can be specially:
Antitheft securing means of the present utility model also comprises bolt head protection buckle closure external member; this external member comprises that the bottom has the ring buckle cover base of bolt hole; be used to protect the annular buckle closure and the elastic circlip of buckle closure base; the buckle closure base outer wall has a base jump ring groove; the inwall of buckle closure has a buckle closure jump ring groove; elastic circlip is a kind of ring with breach; elastic circlip is positioned at base jump ring groove; and when buckle closure was buckled on the buckle closure base, the part that jump ring protrudes from the buckle closure base outer wall was embedded in the buckle closure jump ring groove.
Like this, bolt is passed bolt hole on the buckle closure base, after the implements (as car plate) that needs are fixing are fixing, one side of annular buckle closure is aimed at the indentation, there that is installed on the jump ring in the buckle closure base jump ring groove, make in the jump ring groove that is partially submerged into the buckle closure inboard of jump ring, then, withstand the jump ring of opposite side with hand, slightly firmly buckle closure can be pressed into base, jump ring is embedded in the jump ring groove on base and the buckle closure, thereby buckle closure is just forever withheld on the buckle closure base, bolt head is wrapped in buckle closure and the buckle closure base, and then make this securing means have the effect of double anti-theft.And, by the buckle closure external member bolt head is wrapped in buckle closure and the buckle closure base, also make the profile of securing means more attractive in appearance, formed coordination between built-in and the parts and unified perfect adaptation.
Structure of the present utility model can further be specially:
The outer surface of annular buckle closure has the decorative pattern or the literal of decoration.
Like this, because this securing means is mainly used in the fixed installation of security of outdoor implements, therefore, can have the decorative pattern or the literal of various decorations at the outer surface of annular buckle closure, this decorative pattern or literal can be gravures, also can be protruding seals.Therefore, this securing means not only has antitheft effect, also has the effect of decoration.For example, when this securing means is used for the installation of motor vehicle number plate, can prints as abbreviation, the Chinese character of " Fujian A " and the word of the machine-operated code name of dealing out the cards etc. at the outer surface of buckle closure, thereby also have sign and false proof effect.
The surface of screw bolt and nut all has electrodeposited coating.
The surface of each constituent element of buckle closure external member all has electrodeposited coating.
Like this, the electrodeposited coating of each component surface not only can prevent each component because out of doors wind and weather Exposure to Sunlight and by corrosion, also each component is more attractive in appearance is whole glittering and translucent, also has the effect of decoration.
In sum, the utility model has following advantage compared to existing technology: antitheft securing means of the present utility model can be used in the antitheft fastening effect (as fixing of Automobile registration) that is installed in outdoor implements, not only have simple in structure, easy for installation, the characteristics that Safety performance is good, and overall appearance is coordinated.
