Novel anti-theft nut for pole-tower wire guying

Abstract

The invention relates to a nut, and particularly relates to an anti-theft nut for pole-tower wire guying. The anti-theft nut comprises a nut, wherein a plurality of vertical grooves are arranged in the outer ring of the nut; the nut is provided with a sleeve matched with the same; and the sleeve is as high as the nut. During installation, a first common fastening screw of a wire guying UT wire clamp is screwed at first, and then the nut adopting the design is screwed onto the wire guying UT wire clamp by virtue of the matched sleeve; and when a guy wire needs to be detached in the later period, the nut is unscrewed by virtue of the matched sleeve, the operation is fast and convenient, and the wire guying UT wire clamp can still continue to be used. The anti-theft nut cannot be detached by a thief without the matched special sleeve.

Description

technical field [0001] The invention relates to a nut, in particular to an anti-theft nut for pole and tower stay wires. Background technique [0002] After the power line is completed and put into use, in order to prevent the guy wire from being stolen or destroyed, the following two technical means are mainly adopted at present: first, after the guy wire is installed, smash the wire on the top of the guy wire UT clamp screw with a hammer to make the fixing nut bald. Cannot be disassembled. Although this can achieve the purpose of anti-theft, it will be very troublesome if the line maintenance department wants to remove or adjust the stay wire in the later stage. It is necessary to saw off the stay wire UT clamp screw before disassembly, which is laborious and laborious. destroyed and cannot be used again. The second is to use the existing one-time stay wire anti-theft nut. There is a one-way ball and a spring inside this anti-theft nut, which will not work when the nut...

Problems solved by technology

[0002] After the power line is completed and put into use, in order to prevent the guy wire from being stolen or destroyed, the following two technical means are mainly adopted at present: first, after the guy wire is installed, smash the wire on the top of the guy wire UT clamp screw with a hammer to make the fixing nut bald. cannot be disassembled

Although this can achieve the purpose of anti-theft, it will be very troublesome if the line maintenance department wants to remove or adjust the stay wire in the later stage. It is necessary to saw off the stay wire UT clamp screw before disassembly, which is laborious and laborious. destroyed and cannot be used again

The second is to use the existing one-time stay wire anti-theft nut. There is a one-way ball and a spring inside this anti-theft nut, which will not work when the nut is tightened. The spring is ejected, and the screw thread on the screw is stuck so that the nut cannot be rotated and the nut cannot be disassembled

When the anti-theft nut is broken, the pull wire UT clamp will also be damaged to a certain extent and cannot be used anymore

The patent document (Publication No.: CN102022414A) entitled Universal Anti-theft Nut for Iron Towers discloses an anti-theft nut, which achieves the purpose of anti-theft through the adhesive bonding of the protective sleeve and the anti-theft nut body. Although the purpose of anti-theft can be achieved, it can only be used once. , can not be reused, more wasteful

The patent document (publication number: CN104912896A) titled a kind of anti-theft nut and special sleeve also discloses a kind of anti-theft nut, which can also achieve the purpose of anti-theft through the nut and the protective cap, but its disadvantage is that the structure is complicated, and the protective cap The processing of the connecting part is cumbersome and the cost is high. In addition, the force-bearing area between the nut and the protective cap is small, and repeated disassembly will cause damage and the service life is short.
