Antitheft nut and complete rotator and use method

Abstract

The invention relates to theft-proof nut and matching spinner and its using method. The theft-proof nut includes nut body and spinner. The outer surface of the former is revolution body and set one notch or screw hole; the outer shape of the latter is formed a section of normal nut shape and set corresponding notch or screw through hole. Its using method is that the spinner body is do muff coupling with theft-proof nut body. It has the advantages of simple and reasonable structure, and good theft-proof performance.

Description

technical field [0001] The invention relates to a nut specially used for anti-theft, a matching rotating tool and a use method thereof, belonging to an anti-theft mechanical coupling. Background technique [0002] In the prior art, many telecommunication towers, power towers, landscape towers, etc. are installed in unattended outdoors. Most of these components are hot-dip galvanized steel components, and most of them are connected by bolts. Because these steel components and bolts have greater recycling value, these steel components and bolts have become the object of some criminals stealing. After these bolts and steel components are stolen, it is easy to cause serious potential safety hazards to the original structures such as the tower body. Similar situations may also occur in other application fields of couplings, such as rail fixed connections on railways. [0003] Since the disassembly of the traditional bolt connection is very easy, only a common wrench is needed, ...

Problems solved by technology

[0003] Since the disassembly of the traditional bolt connection is very easy, only an ordinary wrench is needed, so the traditional bolts are easy to be disassembled and stolen outdoors without supervision

Although some special-shaped anti-theft nuts can also be found in the Chinese Patent Gazette at present, these special-shaped anti-theft nuts still have at least one stressed side on their nut bodies, and some senior thieves still have ways to steal them successfully.
