Problems solved by technology

[0002] So far, there is still a lack of anti-theft screw products that are truly effective, easy to assemble and disassemble, and reliable in preventing theft, resulting in a large number of outdoor easy-to-theft facilities being stolen and sold. It has restricted and affected people's production and life to varying degrees.

Abstract

The invention discloses a thermally-treated, quenched and hardened theft-proof nut with a circular-arc outer circumferential wall. The theft-proof nut is a nonstandard nut in a fastener and comprises a thermally-treated, quenched and hardened theft-proof nut body (1), a nut top surface (2), a nut bottom surface (3), a nut outer circumferential wall (4), a nut inner hole top section large-diameter top section hole (5), a nut inner hole bottom section small-diameter bottom section hole (15) and the like, wherein the nut outer circumferential wall (4) is provided with a theft-proof nut convex-waist circular-arc outer circumferential wall (14) and the like. After the theft-proof nut is used together with a thermally-treated, quenched and hardened theft-proof screw with an outer circumferential wall of a corresponding specification and in a corresponding shape, a theft-proof screw fastening high-elasticity gasket, assembly and disassembly tools special for the theft-proof screw such as a convertible sleeve, a spanner and the like, a large number of easily-stolen facilities which are arranged outdoor and belong to the fields of electric power, transportation, environmental protection and the like can be fixedly arranged or replaced in a theft-proof way, and a remarkable social benefit is achieved.

Description

technical field [0001] The present invention is a non-standard nut in a fastener. After it is used together with anti-theft screws of corresponding specifications and shapes, special strong elastic gaskets for anti-theft screws, special tools for assembly and disassembly of anti-theft screws, live top sleeves, and wrenches, the It can be used for anti-theft fixed installation or detachable installation and detachable installation of a large number of easy-to-theft facilities installed outdoors such as electric power, transportation, and environmental protection, and its social benefits are obvious. Background technique [0002] So far, there is still a lack of anti-theft screw series products that are really effective, easy to assemble and disassemble, and reliable in preventing theft, resulting in a large number of outdoor easy-to-theft facilities being stolen and sold. It has restricted and affected people's production and life to varying degrees. Contents of the inventio...
