Abstract
The utility model relates to a screw applied to prevent the license number plate, comprising a bolt and a bolt cover. The bolt cover is provided inside with a housing to hold the bolt head; the housing at least comprises a circular sliding cavity and the bolt head is arranged inside the circular sliding cavity; the tail of the screw is extending outside the housing through the thread rod hole which is communicated with the circular sliding cavity. The utility model is characterized in that: the bolt head is arranged inside the bolt cover, when the screw is in the tightened status, the bolt cover is flexibly matched with the bolt head without any action point between them; moreover, the slotted head screw or the cruciform slot screw is need of a lid of the bolt cover, for the lid of the bolt cover once is enclosed on the bolt cover, which will hardly break away; therefore, the steal of the license number plate is prevented.
Description
[affiliated technical field]
The utility model relates to a kind of link, relates in particular to a kind of novel anti-theft car plate screw of preventing that car plate from being stolen of being used to.
[background technique]
Car plate on the general automobile adopts common link (as screw) to be fixed on the automobile usually, can take out link easily by instruments such as general spanner or screw-drivers, take off car plate, some lawless persons usually steal to sell off behind the car plate and obtain interests or carry out illegal activity, make troubles to the car owner, also give and safeguard that civil order makes troubles.
[summary of the invention]
The purpose of this utility model is to provide a kind of novel anti-theft car plate screw of preventing that car plate from being stolen of being used to, and solves the common link of employing that prior art exists and is fixed on the problem that the car plate on the automobile is stolen easily.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: novel anti-theft car plate screw, it is characterized in that it comprises screw and screw cover, be provided with the screw head receiving cavity in the described screw cover, this receiving cavity includes circular sliding cavity at least, the screw head of described screw places in the described circular sliding cavity, and the screw hole of the afterbody of described screw through being communicated with circular sliding cavity stretches out outside the receiving cavity.Screw head places screw head receiving cavity inner chamber, and instruments such as spanner or screw-driver can't be acted directly on the screw head, and screw head slidably cooperates the possibility of effectively having avoided car plate to be stolen with circular sliding cavity.
As the further of technique scheme improved and replenish, the utility model adopts following technical measures:
Described circular sliding cavity size is at least described screw head circumcircle size, and its degree of depth is at least the thickness of screw head.After screw was fastened to car body, screw head was positioned at circular sliding cavity, and the cavity internal diameter of this part is slightly larger than the screw head circumscribed circle diameter, and the outer surface of screw cover is the cylndrical surface, and instruments such as spanner or screw-driver can't be acted directly on the screw head.
Described screw head receiving cavity also comprises the turning effort chamber of circular sliding cavity upside, and this turning effort cavity shape is corresponding with the screw head shape and size with size, and described screw head is the hex head screw head.The vertical degree of depth of screw head receiving cavity can be the twice of screw head thickness, when the need fastening screw trip bolt, the upper cavity of screw head receiving cavity cooperates with screw head, this moment, screw head was the hex screw head, screw is fastened on the car body, behind fastening finishing, screw head is positioned at screw head receiving cavity lower cavity, and the cavity internal diameter of this part is slightly larger than the screw head circumscribed circle diameter.
Described screw cover is provided with outer torsional interaction portion, and this outer torsional interaction portion is that opening slot or outer surface are hex surface.Can easily screw is fastened on the car body, and at this moment, screw head be positioned at circular sliding cavity directly by instrumental purpose and screw cover, even, also screw head can't be taken out from car body by instrumental purpose and screw cover.
The upper end of described screw head receiving cavity has the screw functional hole, is provided with the screw cover cap that is mated at this screw functional hole place.When the screw of the screw that cooperates with the screw cover for band straight groove or cross recess energy, the screw functional hole is used for instruments such as bottle opener can act directly on screw, after being fastened to its car plate on the car body, cover the screw cover cap, the screw cover cap can be difficult for being fixed on the screw cover of unlatching by welding or other, has further avoided the stolen possibility of car plate.
The beneficial effect that the utlity model has: screw head places in the screw cover, when screw is in tightening state, the screw cover cooperates for movable with screw head, mutual no point of action, and for the screw of being with straight groove or cross recess energy, also need the attachment screw cover cap, in a single day the screw cover cap covers on the screw cover back just can not delamination, thereby it is possible to have prevented that car plate from being stolen.
