Abstract

The invention relates to the technical field of nuts and particularly discloses an antitheft nut which comprises a nut main body and a hexagonal angle firmware; the nut main body takes a cylindrical structure; a metal convex plate is integrally formed on the outer surface of the nut main body and close to the middle along an annular shape; and clamping grooves are formed in the top of the metal convex plate and close to the left and right sides of the nut main body. Through the structural designs of the nut main body, the hexagonal angle firmware, the metal convex plate, the clamping grooves and inserting grooves, the nut main body can carry out rotation and twisting operations through a convex rod with a designated shape only; through the movable connection manner of the nut main body andthe hexagonal angle firmware, a thief is unlikely to discover the position of a blocking metal fixture block; through the structural designs of the clamping grooves and the blocking metal fixture block, the effect for blocking the clamping grooves is effectively realized; and through the structural designs and matching, the antitheft nut is enabled to have the antitheft effect effectively.

Description

technical field [0001] The invention relates to the technical field of nuts, in particular to an anti-theft nut. Background technique [0002] In China, the loss of public facilities property and personal safety due to the loose connection of mechanical parts or man-made theft and damage can reach hundreds of millions of yuan every year, which has a great impact on the healthy operation of the national economy. Anti-theft nuts belong to the anti-theft nuts of the 21st century The latest product with excellent performance is mainly used for the anti-loosening and anti-theft series products of the fastening parts of mechanical components. The anti-theft nut is formed by cold pier without secondary processing. The surface is hot-dip galvanized, and the internal thread has a pair of blind grooves. , the cross-section is arc-shaped, and its radial depth gradually increases against the thread turning. There are two balls in the two blind grooves and are equipped with special plast...
