Description
Technical field
The utility model relates to the antitheft field of nut, refers in particular to a kind of anti-theft nut and socket wrench specially adapted for it.
Background technique
Disclose a kind of anti-theft nut in prior art 201210427614.9, comprise nut body, described nut body external frame is circular, and end face is provided with three deep gouges, three deep gouge Pin form distributions; Because three deep gouges are arranged on end face, adopt common three-jaw spanner also can open, reduce theftproof performance, for this reason, we have developed a kind of anti-theft nut and socket wrench specially adapted for it, by arranging multiple double wedge having spacing with nut exterior edge face on the surface at nut, supporting socket wrench specially adapted for it must be used during dismounting, add anti-theft effect.
Model utility content
The utility model object provides a kind of anti-theft nut and socket wrench specially adapted for it to overcome the deficiencies in the prior art, by arranging multiple double wedge having spacing with nut exterior edge face on the surface at nut, supporting socket wrench specially adapted for it must be used during dismounting, add anti-theft effect.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-theft nut, comprises the nut in ring; The surface of described nut is provided with the double wedge of at least three circle distribution; Each described double wedge and nut exterior edge face are provided with gap; Described nut is arranged with rotating helmet.
Preferably, the angle between described double wedge is not identical.
Preferably, described helmet is provided with back-up ring near the inner place of nut.
The utility model additionally provides a kind of socket wrench specially adapted for it of anti-theft nut, comprises the sleeve that one end is annular; One end of described sleeve annular is provided with the groove corresponding with double wedge; The other end of described sleeve is provided with joint.
Preferably, described joint is Hexagon.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Anti-theft nut described in the utility model, by arranging multiple double wedge having spacing with nut exterior edge face on the surface at nut, makes general spanner cannot contact with double wedge, must use supporting socket wrench specially adapted for it, add anti-theft effect during dismounting.

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-3 is anti-theft nut described in the utility model, comprises the nut 1 in ring; The surface of described nut 1 is provided with the double wedge 11 of six circle distribution; Each described double wedge 11 is concordant with the interior edge face of nut 1, and exterior edge face is provided with gap, and angle between double wedge 11 is not identical, and general spanner cannot be contacted with double wedge 11; Described nut 1 is arranged with rotating helmet 2; Described helmet 2 is provided with back-up ring near the inner place of nut 1, and after nut 1 is locked, helmet 2 prevents from skidding off from nut 1 by back-up ring.
Accompanying drawing 4-5 is the socket wrench specially adapted for it of anti-theft nut described in the utility model, comprises the sleeve 4 that one end is annular; One end of described sleeve 4 annular is provided with the groove corresponding with double wedge 11, nut 1 can only be unscrewed by sleeve 4, play anti-theft effect; The other end of described sleeve 4 is provided with in hexagonal joint, is conveniently connected with common wrench.
During use: bolt 3 is placed in the regular hexagon counterbore on fastener when locking in orthohexagonal head, the other end is by socket wrench specially adapted for it tightening nut 1, and now bolt 3 can not the transfer with the rotation of nut 1; And when rotating helmet 2, only can make helmet 2 rotation, nut 1 can not rotate, and reaches anti-theft effect.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Anti-theft nut described in the utility model, by arranging multiple double wedge having spacing with nut exterior edge face on the surface at nut, makes general spanner cannot contact with double wedge, must use supporting socket wrench specially adapted for it, add anti-theft effect during dismounting.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope
.
