Anti-theft nut for iron tower

Abstract

The invention provides an anti-theft nut for an iron tower. The anti-theft nut comprises a hexagonal nut body, an anti-theft driving assembly, an outer sleeve and an extrusion locking assembly. The hexagonal nut body is mounted in the outer sleeve through the anti-theft driving assembly, the anti-theft driving assembly is disposed between the hexagonal nut body and the outer sleeve, springs are disposed between the anti-theft driving assembly and the outer sleeve, a first driving hexagonal cavity is formed in the center of the anti-theft driving assembly and matched with the hexagonal nut bodyfor installation, a first hexagonal body is disposed under the anti-theft driving assembly, the inner wall of the outer sleeve is provided with a second driving hexagonal cavity cooperating with thefirst hexagonal body, and an idling cavity is formed under the second driving hexagonal cavity. The extrusion locking assembly is mounted in cooperation with the hexagonal nut body and the anti-theftdriving assembly, the extrusion locking assembly controls the anti-theft driving assembly to move downward and drives the first hexagonal body to fall into the idling cavity, the nut body can be effectively prevented from being dismantled, and an anti-theft function is great.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to an anti-theft nut for an iron tower. 【Background technique】 [0002] Most of the fastening structures in the prior art are completed by the cooperation of screws and nuts, and the nuts are screwed into the screws in one direction for fixing, and then unscrewed in the other direction to loosen. When the nuts of the prior art are used to fasten structural parts on field facilities such as electric power, roads, railways, and park sports equipment, they are easily disassembled by others without authorization, thereby causing damage to the facilities, and in some special applications, it may also cause safety problems. Accident, therefore propose a kind of anti-theft nut for iron tower. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose an anti-theft nut for an iron tower, which can effectively prevent th...
