Description
Technical field
The utility model relates to a kind of high voltage iron tower nut, specifically relates to the box-like anti-theft nut of a kind of circular group.
Background technique
Anti-theft nut is mainly for the protection of the not easily stolen effect of high voltage iron tower device; existing anti-theft nut is made up of nut body and restraining groove; nut body inside has a restraining groove, and be provided with spring in restraining groove, spring end is provided with steel ball; and nut body outer ring is provided with the prismatic structure of being convenient to install; the anti-theft nut of this spline structure, because restraining groove is provided with one, and nut outer ring is provided with prismatic structure; there is anti-theft effect difference, nut is easily by the shortcoming of outside destroy.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned existing shortcoming, and the one provided has installs simply, easy to use, and good anti-theft effect, nut cannot by the circular twisting-off anti-theft nut of outside destroy.
The technical solution of the utility model is achieved in that the box-like anti-theft nut of a kind of circular group, comprise nut body, it is characterized in that: the cylindrical structure of described nut body, inside has Anti-theft groove, be provided with steel ball in described Anti-theft groove, described nut body top has wedge shape binding groove, and inner ring is provided with the limited wall raised up, described limited wall top is inverted L-shaped structure, is provided with prismatic fastening ring between described wedge shape binding groove and limited wall.
Described prismatic fastening ring top inner ring has the chamfering coordinating limited wall, and bottom is provided with the wedge shape fastening block coordinating wedge shape binding groove.
Described prismatic fastening ring top has the opening coordinating wedge shape fastening block.
Described wedge shape binding groove is provided with 2-5.
In use: rotate prismatic fastening ring, utilize coordinating of wedge shape fastening block and wedge shape binding groove, drive nut body rotates, and carries out fastening, because limited wall top is inverted L-shaped structure, make spacing for prismatic fastening ring on nut body, cannot remove, wedge shape fastening block, when despining, is pressed in the opening of prismatic fastening ring by wedge shape binding groove by prismatic fastening ring, make to be dismantled by external force, utilize the steel ball of Anti-theft groove inside to play anti-theft function to nut.
The beneficial effects of the utility model are: the box-like anti-theft nut of a kind of circular group of this spline structure has to be installed simply, and easy to use, good anti-theft effect, nut cannot by the advantage of outside destroy.
