Abstract
The utility model relates to a kind of high voltage iron tower anti-theft nut, specifically relates to circular anti-theft nut in a kind of outer prismatic.Circular anti-theft nut in a kind of outer prismatic, comprise nut body, it is characterized in that: the rounded structure of described nut body, inside has Anti-theft groove, be provided with steel ball in described Anti-theft groove, described nut body top is provided with round platform, and described nut body outer ring has for fastening binding groove, described nut body periphery cover has prismatic adapter sleeve, and described prismatic adapter sleeve inside is provided with the fastening block coordinating binding groove.In the outer prismatic of one of this spline structure, circular anti-theft nut has structure simply, cannot force dismounting, advantage easy for installation by external force.
Description
Technical field
The utility model relates to a kind of high voltage iron tower anti-theft nut, specifically relates to circular anti-theft nut in a kind of outer prismatic.
Background technique
Anti-theft nut is stolen mainly for the protection of high voltage iron tower electrical equipment, the effect be not disassembled after making its fastening nuts.
Existing anti-theft nut is mostly offers Anti-theft groove at original nut interior, is provided with steel ball and spring in antitheft, and when nut needs dismounting, steel ball withstands screw, makes it reach anti-theft function.The anti-theft nut of this spline structure exists between nut and screw and has gap, is easily forced the shortcoming of dismounting by external force.
Summary of the invention
The purpose of this utility model is exactly that it is simple that the one provided has structure for above-mentioned existing shortcoming, cannot force dismounting, circular anti-theft nut in outer prismatic easy for installation by external force.
The technical solution of the utility model is achieved in that circular anti-theft nut in a kind of outer prismatic, comprise nut body, it is characterized in that: the rounded structure of described nut body, inside has Anti-theft groove, be provided with steel ball in described Anti-theft groove, described nut body top is provided with round platform, and described nut body outer ring has for fastening binding groove, described nut body periphery cover has prismatic adapter sleeve, and described prismatic adapter sleeve inside is provided with the fastening block coordinating binding groove.
Described binding groove and fastening block are arc-shaped structure, are evenly distributed with 2-4.
The rectangular shape of described binding groove and fastening block contacting point.
Further say: described binding groove and fastening block contacting point are inclination.
Further say: described Anti-theft groove is arc-shaped structure, and inside is provided with block, described block one end is provided with spring, and described spring end is provided with steel ball.
In use: prismatic adapter sleeve is enclosed within nut body, utilize fastening block to coordinate binding groove to be fixedly mounted on screw rod by nut body, because fastening block and binding groove are arc-shaped structure, nut body can only fasteningly cannot be dismantled.
The beneficial effects of the utility model are: in the outer prismatic of one of this spline structure, circular anti-theft nut has structure simply, cannot force dismounting, advantage easy for installation by external force.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As a shown in Figure 6: circular anti-theft nut in a kind of outer prismatic, comprise nut body 1, it is characterized in that: the described rounded structure of nut body 1, inside has Anti-theft groove 2, be provided with steel ball 3 in described Anti-theft groove 2, described nut body top is provided with round platform 4, and described nut body 1 outer ring has for fastening binding groove 5, described nut body 1 periphery cover has prismatic adapter sleeve 6, and described prismatic adapter sleeve 6 inside is provided with the fastening block 7 coordinating binding groove 5.
As Figure 1-5: described binding groove 5 and fastening block 7, in arc-shaped structure, are evenly distributed with 2-4.
As shown in Figure 2,3: described binding groove 5 and the rectangular shape 8 in fastening block 7 contacting point.
As shown in Figure 4,5: described binding groove 5 is inclination 9 with fastening block 7 contacting point.
As shown in Figure 1: described Anti-theft groove 2 is in arc-shaped structure, and inside is provided with block 10, and described block 10 one end is provided with spring 11, and described spring 11 end is provided with steel ball 3.
In use: be enclosed within nut body 1 by prismatic adapter sleeve 6, utilize fastening block 7 to coordinate binding groove 5 to be fixedly mounted on screw rod by nut body, because fastening block 7 and binding groove 5 are in arc-shaped structure, nut body 1 can only fasteningly cannot be dismantled.
In the outer prismatic of one of this spline structure, circular anti-theft nut has structure simply, cannot force dismounting, advantage easy for installation by external force.
