Abstract
The utility model relates to an anti-theft device used to reinforce iron tower, metal component of road and bridge, which mainly solves the problem of bad anti-theft effect of prior technology and low fastening strength. Characterized in that a spring washer with a certain diameter and thickness is set at bottom outlet of U jacket on bolt and pipe-shaped stuffs are arranged between the U jacket and nut, the utility model can not be disassembled with any standard and non-standard wrench, case and socket wrench, so as to achieve purpose of theft protection and fastening. Characterized in reasonable structure, convenient usage and ideal effect of theft protection, the utility model is extensively applied in electric power, traffic and communication industry.
Description
Affiliated technical field
The utility model relates to a kind of iron tower, the anti-theft device of road and bridge metal construction.
Background technique
At present, China's electric power, metal construction on the iron tower of communication section and railway, highway and the oil field oil transport pipeline all adopts bolt, nut to fix, steal phenomenon is very serious, the collapse accident that iron tower causes because of member is stolen happens occasionally, the road and bridge member is stolen to bring serious hidden danger to traffic safety, has not only had a strong impact on its security of operation, has more caused enormous economic loss to country.
Solve the technology of the stolen problem of metal construction now, mainly adopted the nut weldering dead; Fluting is beaten the way of pin on screw bolt and nut, and certain anti-theft effect is arranged, but rocks along with iron tower, bridge are operating and shake, and member easily becomes flexible.The sheath that employing suit protection nut between bolt, nut is also arranged because of fastening back sheath closely contacts with nut, though be difficult to open nut with spanner, can be pulled down sheath with pipe wrench easily together with nut.
Summary of the invention
The purpose of this utility model provides a kind of gold utensil anti-theft device, and it is poor to solve the prior art anti-theft effect, and easily loosening problem realizes antitheft, the tight purpose of fixed component.
Technical solutions of the utility model: be with spring washer in the U-shaped sheath bottom outlet on the bolt, this washer outer diameter is less than the bottom outlet aperture of U-shaped sheath, and its thickness is provided with tubular filler greater than U-shaped sheath bottom outlet wall thickness between nut and sheath, and fastening back U-shaped sheath is rotatable.
Remarkable advantage of the present utility model: rational in infrastructure, it is loosening that spring washer is difficult for metal construction, and the embedding of rotating U-shaped sheath and tubular filler can't be dismantled any standard, off-gauge spanner, cover bucket and pipe wrench instrument, has significant anti-theft effect.
Introduce the utility model below in conjunction with drawings and Examples
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure 1, nut, 2 bolts, 3, spring washer, 4, nylon tube, 5, the U-shaped sheath, 6, metal construction
Known that by figure on the bolt 2 between nut 1 and the hardware 6, cover has protection nut 1 U-shaped sheath 5, on the bolt of U-shaped sheath 5 bottom orifices also cover spring washer 3 arranged. At U-shaped Establish nylon tube 4 between sheath 5 and the nut 1.
Embodiment
More than the U-shaped sheath 5 wall thickness 1.5mm; Spring washer 3 thickness are greater than U-shaped sheath 5 wall thickness 0.2mm, and spring washer 3 external diameters are less than U-shaped sheath 5 bottom diameter 0.2mm, nylon tube 4 tight attached nuts 1, with the spacing of U-shaped sheath 5 be 0.2mm.Nylon tube 4 is contour with nut 1.
