Abstract
The utility model relates to an anti-theft screw bolt and screw nut device and a wrench used on an electric power transmission tower, belonging to a fastener and a special assembling and disassembling instrument. Head parts of the screw bolt and the screw nut form a column shape, three shaped grooves are uniformly distributed on the side circumference of the cylinder, the bottoms of the shaped grooves are plane surfaces, two side surfaces are cambered surfaces and the two cambered surfaces and the bottom plane surfaces form a wedge-shaped groove. The shape of a working end of the special spanner matches with the outline surfaces of the shaped grooved of the screw bolt and the screw nut. The utility model has a strong special performance and can prevent the general theft of the components of the electric power transmission tower.
Description
The utility model relates to a kind of power transmission tower theftproof bolt nut device and spanner that belongs to fastening piece and special handling tool.
Common fastener bolt nut profile is a hexagon, and versatility is very strong, and this brings great convenience to the user.But the very strong fastening piece of this just versatility also brings convenience to stealer.Annual power transmission tower member is robbed or burgled very serious, causes very big loss for electric industry department.
The purpose of this utility model is exactly to provide a kind of power transmission tower theftproof bolt nut device and spanner that has shaped grooves for solving the deficiencies in the prior art.
The purpose of this utility model is achieved in that the bolt head of power transmission tower anti-theft bolt is cylindrical, uniform three identical shaped grooves on the cylindrical side circumference, the end of described shaped grooves is the plane, and two sides are cambered surface, and two cambered surfaces and bottom plane constitute wedge slot; The power transmission tower anti-theft nut is cylindrical, uniform three identical shaped grooves on the cylindrical side circumference, and the end of described shaped grooves is the plane, and two sides are cambered surface, and two cambered surfaces and bottom plane constitute wedge slot; The wedge shape projection that is shaped as two cambered surfaces composition of the working end of power transmission tower Anti-theft wrench and the wedge slot that two cambered surfaces are formed, its outer surface matches with the shaped grooves outer surface of above-mentioned bolt and nut.The handle plane of the relative spanner in plane, working end of spanner remains on two planes.
The utility model is compared figure viewed from behind technology and is had following advantage:
1, because theftproof bolt nut is provided with shaped grooves, the handling instrument special use can prevent effectively that the generality of power transmission tower member from stealing.
Fig. 1 is the anti-theft nut plan view.
Fig. 2 is the anti-theft nut left view.
Fig. 3 is the anti-theft bolt plan view.
Fig. 4 is an anti-theft bolt A-A sectional view.
Fig. 5 is a theftproof bolt nut user mode plan view.
Fig. 6 is a theftproof bolt nut user mode plan view.
Fig. 7 is the Anti-theft wrench plan view.
Fig. 8 is that spanner F is to view.
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2, and 120 ° of uniform three identical shaped grooves on the circumference of nut cylinder.As shown in Figure 3, Figure 4,120 ° of uniform three identical shaped grooves on the circumference of the head side of anti-theft bolt.Certainly, shaped grooves also can be made other shape, as long as the working end shape of assurance spanner as shown in Figure 7 and shaped grooves match to merge bolt or nut is twisted.As shown in Figure 8, the plane, working end of spanner and the handle plane of spanner be not or not same plane, and be easy to use like this.As shown in Figure 5, anti-theft nut 1 fastens member 3 with anti-theft bolt 2, uses special spanner as shown in Figure 7 can tighten or unscrew anti-theft nut 1 and anti-theft bolt 2.
