Abstract
The utility model relates to a split anti-theft nut which is characterized by consisting of a clamping sleeve body and a screw body, wherein the clamping sleeve body is a structure which has a cylindrical outer part and a hollow round-platform-shaped inner part; the screw body is divided into a conicity thread sleeve and a mounting nut; the outer part of the conicity thread sleeve is provided with a hollow round platform structure identical with the clamping sleeve body, and the inner part thereof is provided with threads; the inner part of the mounting nut is provided with a hollow cavity with the diameter larger than the outer diameter of a bolt, and the outer part thereof is provided with a prism structure; and the circle of the outer upper angle of the conicity thread sleeve and that of the inner lower angle of the mounting nut are connected into a whole. The split anti-theft nut has simple and convenient installation and low cost, also can be installed by using a common spanner, and can not be disassembled by the spanner after being installed.
Description
Technical field
The utility model relates to a kind of nut, particularly relate to a kind of in field facilities such as electric power system, communication system and expressway the anti-theft nut of fastenings or member.
Background technique
In the prior art, in order to reach better anti-theft effect, the outside of anti-theft nut is columniform, in order that prevent from destructively to unload with spanner, such nut one end has mounting groove; Must use special-purpose instrument to install during installation, this has just brought trouble to installation.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, and a kind of split type anti-theft nut that can use common wrench to install is provided.
The purpose of this utility model is achieved in that split type anti-theft nut, it is characterized in that being made up of cutting ferrule body and screw body; It is cylindrical that described cutting ferrule body is that the outside has, and inside has the structure of hollow frustoconic shape; Screw body divides the tapering silk braid again and nut two-part is installed, and tapering silk braid outside has the structure of the hollow round platform of identical cutting ferrule body, and inside has screw thread; Installation nut inside has the cavity greater than the bolt external diameter, and the outside has prism structure; The outer of tapering silk braid gone up a week at angle and being connected as a single entity in one week of inner lower angle of nut is installed.
The beneficial effects of the utility model are: since anti-theft nut taked split-type structural have simple installation, cost low, can also use common spanner to install, the effect that can not unload with spanner after the installation.
