Abstract
The utility model relates to a screw nut, in particular to an anti-theft screw nut which comprises an anti-theft screw nut body and a protecting sleeve, wherein the outline of the anti-theft screw body is cylindrical; the protecting sleeve is a barrel with the inner diameter larger than the outer diameter of the anti-theft screw nut body; the anti-theft screw nut body and the protecting sleeve are provided with clamping grooves which are mutually coincided; the protecting sleeve is sheathed at the periphery of the anti-theft screw nut body in a clamping way, and movably connected with the periphery of the anti-theft screw nut body; and the upper end surface of the anti-theft screw nut body is also provided with a wedge installation groove from shallow to deep along the installation direction of the screw nut. The anti-theft screw nut of the high protecting sleeve has anti-theft function, and can be widely applied to electric power systems, communication systems and highways.
Description
Technical field
The utility model relates to a kind of nut, relate to a kind of in field facilities such as electric power system, communication system and expressway the anti-theft nut of the anti-theft nut, particularly a kind of high protecting cover of fastenings or member.
Background technique
Present anti-theft nut has nut body and protecting cover, the profile of nut body is cylindrical, protecting jacket is the tubular of an internal diameter greater than this body diameter of anti-theft nut, anti-theft nut body and protecting cover have the draw-in groove that coincide mutually, and the periphery that protecting cover is enclosed within the anti-theft nut body sticks and rotatable connection; The anti-theft nut body has the height higher than protecting cover, because protecting cover than higher, brings certain influence to anti-theft effect.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, and a kind of anti-theft nut of better effects if is provided.
The purpose of this utility model is achieved in that a kind of anti-theft nut of high protecting cover, comprise nut body and protecting cover, the profile of nut body is cylindrical, protecting cover is the tubular of an internal diameter greater than the nut body external diameter, anti-theft nut body and protecting cover have the draw-in groove that coincide mutually, and the periphery that protecting cover is enclosed within nut body sticks and rotatable connection; The upper-end surface of nut body also has along the wedge shape mounting groove of nut installation direction by shallow intensification; It is characterized in that: protecting cover has the height higher than nut body.
The beneficial effects of the utility model are: the protecting cover of such anti-theft nut has higher height, helps the protection of nut body, can further reach antitheft purpose.
