Abstract
The utility model provides a license plate anti-theft fastening screw, comprising a screw body and a screw fastening head. The screw body consists of a screw rod and a screw head; the screw fastening head is connected with the screw head by a conical connector which is connected with the screw head by the conical tip; the cross section of the screw fastening head can be a tetrahedron, hexahedron or octahedron, and the head face of the screw fastening head is provided with a reversed I-shaped groove or a cross groove. The license plate anti-theft fastening screw has the advantages that the structure is simple; and when the screw fastening head is snapped, the license plate anti-theft fastening screw can ensure that the screw head is flat, thus having obvious anti-theft effect and being applicable to various license plates.
Description
Technical field
The utility model relates to a kind of antitheft fastening screw trip bolt, and refering in particular to is a kind of license-plate anti-theft fastening screw trip bolt that prevents that car plate is stolen.
Background technique
In the market, when the mounting vehicle licence plate, the plain bolts that use more, plain bolt is easy to use general tool, loosening as bottle opener, pliers etc., in China Patent No. be: 96234975.5, name is called in " license-plate anti-theft bolt " and discloses a kind of anti-theft bolt, and the cylindrical body that is screw diameter 1/2 to 1/6 with diameter between its screw fastener head and the screw head is connected.After installation is tightened, fastener head is connected cylindrical body knock out, realize antitheft function.But when the use of reality, when knocking out fastener head and cylindrical body, because cylindrical diameter is equally thick up and down, the position that is easy to occur rupturing is the place that cylindrical body and fastener head join.Rather than the place that links to each other with screw head of cylindrical body, can on screw head, leave over one section cylindrical body like this, do not have antitheft effect.Knock out as will leave over one section cylindrical body with brute force, be easy to damage car plate again.
The model utility content
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and is easy for installation, the license-plate anti-theft fastening screw trip bolt of good anti-theft effect.
The purpose of this utility model is achieved by following technical proposals:
Comprise screw body, screw fastener head, screw body comprises screw mandrel and screw head, links to each other by the taper connection body between described screw fastener head and the described screw head.
Described taper connection body links to each other with screw head by the awl point.
Described screw fastener head cross section is tetrahedron, hexahedron or octahedron.
Described screw fastener head end face is provided with " one " word or " ten " word groove.
The utility model adopts technique scheme, during installation, at first tighten screw, entangle the screw fastener head with sleeve, the screw fastener head is fractureed from the position that the taper connection body links to each other with screw head with the taper connection body, because the position that the taper connection body links to each other with the screw fastener head is the thickest position of taper connection body, and the position that the taper connection body links to each other with screw head is the most tiny position of taper connection body, like this, and when fractureing, can guarantee that the smallest end position that links to each other with screw head at the taper connection body fractures, make screw head become a plane, the place that general instrument is not puted forth effort can't screw out screw, prevented that car plate is stolen, the utility model is simple in structure, behind the screw fastener head of guaranteeing to fracture, makes screw head become a plane, anti-theft effect is obvious, is applicable to all kinds of car plates.
Description of drawings
Figure is a license-plate anti-theft fastening screw trip bolt structural representation.
In the accompanying drawing, 1-screw fastener head, 2-taper connection body, 3-screw head, 4-screw mandrel.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As figure, comprise screw body, screw fastener head 1, screw body comprises screw mandrel 4 and screw head 3, link to each other by taper connection body 2 between described screw fastener head 1 and the described screw head 3, described taper connection body 2 links to each other with screw head 3 by the awl point, described screw fastener head 1 cross section is a tetrahedron, hexahedron or octahedron, described screw fastener head 1 end face is provided with " one " word or " ten " word groove, during installation, at first tighten screw, entangle screw fastener head 1 with sleeve, screw fastener head 1 is fractureed with the position that screw head 3 links to each other from taper connection body 2 with taper connection body 2, because the position that taper connection body 2 links to each other with screw fastener head 1 is the thickest position of taper connection body 2, and the position that taper connection body 2 links to each other with screw head 3 is the most tiny position of taper connection body 2, like this, when fractureing, can guarantee to fracture at the smallest end position that taper connection body 2 links to each other with screw head 3, make screw head 3 become a plane, the place that general instrument is not puted forth effort, screw can't be screwed out, prevent that car plate is stolen.
