Abstract
The utility model discloses a special eccentric washer for directional wall-mounted non-rotating antitheft screws, which is a nonstandard washer in fasteners and comprises a special eccentric washer body (1), a washer top surface (2), a washer bottom surface (3), a washer peripheral wall (4) and a washer internal through hole (5), the washer peripheral wall (4) is provided with a washer edge-to-edge planar interval peripheral wall (14), and the washer internal through hole (5) is changed into a washer edge-to-edge planar interval eccentric internal through hole (15) or washer elliptical eccentric internal through hole (25). After being used with a special free-jack sleeve and wrench and the like in corresponding shape and specification and capable of serially mounting screws, antitheft nuts and antitheft screws but incapable of rotating, the eccentric washer can fix and install a great amount of outdoor electric power, telecommunication, environment-friendly facilities and the like easy to be stolen for antitheft purpose, and achieves obvious social benefits.
Description
Technical field
The utility model is the nonstandard pad in a kind of fastening piece, the anti-theft nut of it and respective shapes and specification, only for the anti-theft nut special use can only go here and there dress can not the supporting uses such as screw, anti-theft screw special-purpose work top sleeve and spanner of turn after, can carry out fixed installation of security to being installed on outdoor easy pirate facilities such as electric power in a large number, its social benefit is obvious.
Background technique
To ending at present, still lack real effectively, mounting or dismounting convenience, antitheft reliable anti-theft screw, anti-theft screw accessory and anti-theft screw assembly and Disassembly special tool series product, cause a large amount of outdoor easy pirate facilities fixedly to cause the people for being stolen and sold because of what lack anti-theft screw, 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, providing the directed wall that leans on of convenient, the antitheft reliable the utility model of a kind of mounting or dismounting simple in structure, cheap, supporting not rotate the special-purpose eccentric washer technology of anti-theft screw.
The technological scheme that its technical problem that solves the utility model adopts is:
The utility model is directed not to rotate the special-purpose eccentric washer of anti-theft screw by wall, comprise and directed do not rotate the special-purpose eccentric washer lamellar body 1 of anti-theft screw, lamellar body end face 2, lamellar body bottom surface 3, lamellar body periphery wall 4 and lamellar body inner via hole 5, on lamellar body periphery wall 4, be provided with the alternate periphery wall 14 of lamellar body rib, on lamellar body inner via hole 5, lamellar body inner via hole 5 changed and be made as alternate eccentric inner via hole 15 of lamellar body rib or the eccentric inner via hole 25 of lamellar body ellipse with the rib plane with the rib plane by wall.
In the alternate eccentric inner via hole 15 of lamellar body rib, be provided with alternate with the rib plane eccentric inner via hole wall of the alternate eccentric inner via hole wall rib 151 of lamellar body rib plane 152 with the lamellar body rib with the rib plane with the rib plane.In the oval eccentric inner via hole 25 of lamellar body, be provided with the oval eccentric inner via hole wall 251 of lamellar body.
The beneficial effects of the utility model are:
1, the anti-theft nut of the utility model and respective shapes and specification, only for the anti-theft nut special use can only go here and there dress can not the supporting uses such as screw, anti-theft screw special-purpose work top sleeve and spanner of turn after, can carry out fixed installation of security to being installed on easy pirate facilities such as outdoor electric power, telecommunications, environmental protection in a large number, its social benefit is obvious.
2, the utility model mounting or dismounting simple in structure, cheap, supporting are convenient, antitheft installation is reliable, and social benefit is obvious.
