Abstract
The utility model relates to a high strength anticorona bolt. The strength anticorona bolt comprises a blot and a nut, wherein the bolt comprises a rod body and a thread section; the thread section is provided with a pin hole 1, and the upper end surface of the bolt is spherical; the length of an internal thread of the nut is the same as that of the thread section of the bolt, and the nut is provided with a pin hole 2 matched with the pin hole 1; and the upper end surface of the nut is arc. The high strength anticorona bolt disclosed by the utility model is made from 45# steel, the strength is enhanced by heat processing, and the processing length of the thread is shortened, thereby reducing the consumption of materials and the production cost; the outlines of the bolt and the nut are in smooth transition, thereby greatly reducing the possibility of generating a corona; a groove is arranged at the middle part of the nut, so that the length of a closed pin is shortened for mounting conveniently; after the bolt, the nut and the closed pin are matched, the ends of the bolt and the nut are leveled, the overall length of the bolt is shortened, and the production cost is saved.
Description
Technical field
The utility model relates to the assembly in a kind of electric power project of transmitting and converting electricity, relates in particular to the anti-corona bolt of a kind of high strength.
Background technique
After common hexagonal headband Pin hole bolt is installed, because thread section length is longer on the bolt, the connecting part of nut and thread section is shorter, thereby causes on the bolt thread section utilization ratio not high, and the bolt entire length is elongated, wasted cost of production, have the gap between nut and the pin, after long-term the use, nut is understood downside pin and is tightened between the position loosening, connect insecurely, have potential safety hazard; The end face of bolts and nuts mostly is greatly the plane, produces easily the corona befouling environment.
The model utility content
The utility model provides a kind of and has reduced material consumption, reduced production costs, is connected firmly, places the anti-corona bolt of high strength of corona in order to overcome the above problems.
The technical solution of the utility model is: comprise screw bolt and nut, described bolt comprises the body of rod and thread section, and described thread section is provided with pin-and-hole one, and the bolt upper-end surface is sphere; The length of thread section is identical on described nut inner thread length and the bolt, described nut be provided with bolt on the suitable pin-and-hole two of pin-and-hole one, described nut upper-end surface is circular-arc.
Described nut middle part is groove, and described pin-and-hole two is arranged in the groove.
The utility model adopts No. 45 steel makings to improve intensity through Overheating Treatment, be processed with the closed pin mounting hole on the bolts and nuts, after the installation, bolt and nut closed pin relative position is fixed, the situation that does not have nut loosening, and the processing length of screw thread shortens, and reduced the consumption of material, reduced cost of production, screw bolt and nut profile rounding off reduces the possibility that corona produces greatly, and groove is left at the nut middle part, shortened the length of closed pin, be convenient to install, after the bolt and nut closed pin cooperated, the bolt and nut end face was concordant, the bolt entire length shortens, and saves production cost.
