Anti-theft nut, anti-theft screw and operating pliers for outdoor power facilities

Abstract

The invention relates to an anti-theft nut, an anti-theft screw and operating pliers for outdoor electric facilities, belonging to the technical field of fasteners. The anti-theft nut and anti-theft screw head of the present invention have end face teeth on the end faces facing the connected parts, and the end face teeth are engaged with the matching operating pliers to obtain rotational driving force for assembly and disassembly, which can avoid illegal knocking And loose. The sheath and protective cap do not affect the assembly and disassembly operation of the operating pliers, and the installation is completed through closing processing at the manufacturer, which can improve the structural strength. The elastic sealing layer in the sheath and the protective cap can prevent dust, water and grease from entering to cause jamming and rust, can cushion when being knocked illegally, and can also absorb impact energy due to free rotation. The opening of the operating pliers of the present invention can be enlarged, and anti-theft nuts and anti-theft screws of different specifications can be assembled and disassembled. The anti-theft method of the present invention provides a huge coding space for pairing the operating pliers with the anti-theft nuts or anti-theft screws, and can avoid illegal disassembly of unmatched operating pliers.

Description

technical field [0001] The invention relates to a nut, a screw and an operating pliers thereof, belonging to the technical field of fasteners. Background technique [0002] The nut is usually a short hexagonal cylindrical structure with a central threaded hole, and the inner surface of the central threaded hole has an internal thread, which needs to be matched with a bolt to fasten two connected parts with through holes. Screws, also known as screws, are threaded fasteners with a head and a screw rod, with external threads on the surface of the screw rod, used to fasten a connected part with a through hole to another one with a threaded hole The connected parts do not need to cooperate with the nut. [0003] In order to effectively avoid the theft of outdoor power facilities, people have proposed multiple anti-theft nuts and anti-theft screws; existing nut and screw anti-theft technologies mainly contain four kinds. The first is the anti-theft technology that cannot be loo...

AI Technical Summary

Problems solved by technology

The anti-theft technology that cannot be loosened is convenient and reliable, but the disadvantage is that it is difficult to break and disassemble, and the bolts, screws and nuts can only be used once

[0004] The second is the anti-theft technology of one-way drive rotation, which can only be driven by tools in one direction, and rotates in the direction of fastening, and cannot be rotated in the opposite direction, so it cannot be disassembled; such as nuts with balls, screws with one-way drive structure head

[0009] The existing anti-theft technology with detachable and protective caps has insufficient anti-theft capability and is easy to be broken through illegally, so it needs to be improved
