Abstract
The utility model discloses a theft-proofing nut capable of being disassembled only by unique special tool. The theft-proofing nut is a nonstandard nut in fastening pieces and comprises a theft-proofing nut body of which the rigidity is increased by heat-treatment quenching and a nut peripheral wall and the like, a small-diameter top segment peripheral wall of the nut peripheral wall and a large-diameter bottom segment peripheral wall of the nut peripheral wall are arranged on the nut peripheral wall; right-hand screw threads of the small-diameter top segment peripheral wall of the nut or left-hand screw threads of the small-diameter top segment peripheral wall of the nut are arranged on the small-diameter top segment peripheral wall of the nut peripheral wall, and left-hand screw threads of the large-diameter bottom segment peripheral wall of the nut or right-hand screw threads of the large-diameter bottom segment peripheral wall of the nut are arranged on the large-diameter bottom segment peripheral wall of the nut peripheral wall. After the theft-proofing nut is matched with a theft-proofing screw, a theft-proofing washer, and unique special tools for the theft-proofing screw, including a shoring sleeve and a wrench and the like, which have the corresponding shape and specifications, a great amount of outside facilities in the electric power, traffic, environmental-protection field, which are easy to be stolen, can be fixed by the theft-proofing nuts or old parts are replaced by new parts, the social benefit is remarkable.
Description
Technical field
The utility model is the nonstandard nut in a kind of fastening piece, anti-theft screw, anti-theft pad and the anti-theft screw of it and respective shapes and specification installed and removed unique special tool and lived after the supporting uses such as top sleeve, spanner, can carry out fixed installation of security or tear trade-in open having installed and used to being installed on easy pirate facilities such as outdoor electric power, traffic, environmental protection in a large number, its social benefit be obvious.
Background technique
To ending at present, still lack real effectively, convenient, the antitheft reliable anti-theft screw of mounting or dismounting and assembly and Disassembly special tool series product thereof, cause a large amount of outdoor easy pirate facilities constantly to be stolen and sold, it has caused restriction and influence in various degree to people's production, life.
Summary of the invention
The purpose of this utility model is for overcoming deficiency of the prior art, provide a kind of simple in structure, mounting or dismounting are convenient, antitheft reliable, cheap the utility model has only the anti-theft nut technology of using unique special tool just can install and remove.
The technological scheme that its technical problem that solves the utility model adopts is:
This practicality has only the anti-theft nut that uses unique special tool just can install and remove, comprise that heat-treatment quenching increases hard anti-theft nut parent 1, nut periphery wall 2, nut bottom surface 3, nut end face 4, nut inner via hole 5, nut inner via hole wall 6 and nut inner via hole wall right-handed thread 7 or nut inner via hole wall left-handed thread 8, section periphery wall 22 at the bottom of being respectively equipped with nut periphery wall minor diameter top section periphery wall 21 and nut periphery wall major diameter on the nut periphery wall 2; On nut periphery wall minor diameter top section periphery wall 21 or be provided with a nut minor diameter top section periphery wall dextrorotation spiral shell section 211 or a nut minor diameter top section periphery wall left-handed thread 212 on its part periphery wall, section periphery wall right-handed thread 222 at the bottom of being provided with at the bottom of the nut major diameter section periphery wall left-handed thread 221 or nut major diameter on the section periphery wall 22 at the bottom of the nut periphery wall major diameter or on its part periphery wall.
The diameter of described nut minor diameter top section periphery wall right-handed thread 211 or nut minor diameter top section periphery wall left-handed thread 212 less than the nut major diameter at the bottom of the diameter of section periphery wall right-handed thread 222 at the bottom of section periphery wall left-handed thread 221 or the nut major diameter.
The beneficial effects of the utility model are:
1, after the utility model and corresponding specification, the anti-theft screw of shape, anti-theft pad, anti-theft screw are installed and removed supporting uses such as unique special tool top alive sleeve, spanner, can carry out fixed installation of security or tear trade-in open having installed and used to being installed on easy pirate facilities such as outdoor electric power, traffic, environmental protection in a large number, its social benefit be obvious;
2, the utility model is simple in structure, mounting or dismounting are convenient, antitheft reliable, cheap, social benefit is obvious.
