Description
Technical field
The utility model relates to anti-theft screw.
Background technique
Described screw comprises nuts and bolt, and nuts and bolt coordinates; In prior art, anti-theft screw has various ways, but it has or complex structure, or anti-theft effect is poor, or installs the shortcomings such as inconvenience, is unfavorable for installing and using.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of easy to install, simple anti-theft screw of good anti-theft effect, structure.
The technical solution of the utility model is achieved in that a kind of anti-theft screw, comprise nuts and bolt, nuts and bolt coordinates, and it is characterized in that: described nut side is provided with the through hole of a taper, also have a pin coordinating through hole, the tapering of described through hole is 5-10 °.
Say further, the top of described pin is most advanced and sophisticated or has blade.
Say further, described bolt side has one or multi-channel groove vertically, and multiple tracks groove is evenly distributed on the sidewall of bolt, the tip of such pin or have blade better effects if in groove.
The beneficial effects of the utility model are: such anti-theft screw has easy to install, the simple advantage of good anti-theft effect, structure; After nut is screwed to position on bolt, pin is pounded with hammer, pin is arrived inside through hole, because original pin is the respective outer side edges with through hole, under hammer active force, through hole is expanded, the face of pin is lower than the face outside nut, have good anti-theft effect, described through hole is taper, has the advantage that pin more easily enters through hole; The top of described pin is most advanced and sophisticated or has blade, and described bolt side has one or multi-channel groove vertically, and multiple tracks groove is evenly distributed on the sidewall of bolt, has the better advantage of antitheft locating effect.
