Abstract

The invention relates to high-voltage iron tower antitheft nuts, in particular to an antitheft nut with the prismatic exterior and the circular interior. The antitheft nut with the prismatic exterior and the circular interior comprises a nut body and is characterized in that the nut body is of a circular structure; an antitheft groove is formed in the nut body; a steel ball is mounted in the antitheft groove; a circular truncated cone is arranged on the upper portion of the nut body; fastening grooves used for fastening are formed in an outer ring of the nut body; the nut body is sleeved with a prismatic fastening sleeve; and fastening blocks matched with the fastening grooves are arranged in the prismatic fastening sleeve. The antitheft nut with the prismatic exterior and the circular interior which is of the structure has the advantages of being simple in structure and convenient to mount and cannot be forcefully dismounted through external force.

Description

technical field [0001] The invention relates to an anti-theft nut for a high-voltage iron tower, in particular to an anti-theft nut with an outer prismatic shape and an inner circle. Background technique [0002] The anti-theft nut is mainly used to protect the high-voltage tower electrical appliances from being stolen, so that the nut will not be disassembled after being tightened. [0003] Most of the existing anti-theft nuts are provided with anti-theft grooves inside the original nuts, and steel balls and springs are installed in the anti-theft nuts. When the nuts need to be disassembled, the steel balls withstand the screws to achieve the anti-theft effect. The anti-theft nut with such a structure has the disadvantage that there is a gap between the nut and the screw, and it is easy to be forcibly disassembled by external force. Contents of the invention [0004] The purpose of the present invention is to solve the above-mentioned shortcomings, and provide a simple s...
