Description
[technical field]
The utility model relates to the technical fields of the technical field of bolt, especially anti-theft bolt.
[background technique]
Bolt: machine components, the cylindrical threaded fastener of adapted nut.By head and screw rod with externally threaded
Cylindrical body a kind of fastener dimerous, need to cooperate with nut, antitheft for being fastenedly connected two parts for having through-hole
Bolt is one of bolt, and anti-theft bolt is also known as anti-demounting bolt, in the major businessman of today's society in order to safeguard itself
Interests and use anti-theft bolt, its application field of anti-theft bolt is very extensive, as: electric power facility, rail facility, highway
Facility, field facility, city lighting street lamp facility, lamp automobile tire and public fitness equipment etc., anti-theft bolt, which is divided into, to be filled
Detachable anti-theft bolt and it can fill not detachable anti-theft bolt, and electric power tower is steel frame construction, pylon builds the power generation in field more
Near factory, power distribution station, it is the critical facility of power department, and energy trolley wire simultaneously plays a part of to protect and support, electric power tower
Design, manufacture, installation, maintenance and quality testing be modern power systems operation and development important leverage, electric power tower is
Enhancing anti-theft performance can largely use anti-theft bolt, and how complex existing anti-theft bolt is, high production cost, anti-theft performance compared with
It is general.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of non-dismountable type of electric power tower
Anti-theft bolt is capable of the anti-theft performance of strengthening stud, and structure is simple, and production cost is low.
To achieve the above object, the utility model proposes a kind of non-dismountable type anti-theft bolts of electric power tower, including
Stud, screw head, it is antitheft screw card tooth, dome main body, the stud surface is equipped with screw thread, and the stud upper end is equipped with screw head,
The screw head is cylindrical type, the screw head side be equipped with it is several it is antitheft screw card tooth, the described antitheft Ka Ya and anti-of screwing
Robber screws to be placed equidistant between card tooth, and the screw head upper end is equipped with dome main body.
Preferably, the screw head lower end is equipped with anti-loosening lines.
Preferably, it is described it is antitheft screw card tooth at least there are two.
Preferably, the antitheft card tooth cross section that screws is triangle, the antitheft card tooth that screws includes major part
End and tail end, the tail end is concordant with screw head, and the direction of the stub end is contrary with screwing for stud.
Preferably, the center of the stud, screw head and dome main body is on same axis.
Preferably, the stud, screw head, antitheft screwing Ka Ya and dome main body is an integral molding structure.
Preferably, the screw head and dome head surface is smooth burnishing surface.
The utility model has the beneficial effects that the utility model by by stud upper end be arranged screw head, if in screw head be arranged
Do it is antitheft screw card tooth, the antitheft stub end for screwing card tooth is blocked by specific purpose tool and tightens bolt, screws card due to antitheft
Tooth derotation does not have impetus, can not be by the antitheft card tooth that screws by Bolt dismantling, and the anti-loosening lines of screw head lower end setting can be with
Frictional force between strengthening stud and nut or workpiece enhances the anti-loosening performance of bolt.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of structural schematic diagram main view of the electric power tower of the utility model with non-dismountable type anti-theft bolt；
Fig. 2 is a kind of structural schematic diagram top view of the electric power tower of the utility model with non-dismountable type anti-theft bolt.
In figure: 1- stud, 2- screw head, 3- are antitheft to screw card tooth, 4- dome main body, 11- screw thread, the anti-loosening lines of 21-, 31-
Stub end, 32- tail end.
[specific embodiment]
Refering to fig. 1 and Fig. 2, a kind of electric power tower of the utility model non-dismountable type anti-theft bolt, including stud 1, spiral shell
First 2, antitheft to screw card tooth 3, dome main body 4,1 surface of stud is equipped with screw thread 11, and 1 upper end of stud is equipped with screw head 2,
The screw head 2 is cylindrical type, 2 side of screw head be equipped with it is several it is antitheft screw card tooth 3, it is described antitheft to screw card tooth 3
It is placed equidistant between card tooth 3 with antitheft screw, 2 upper end of screw head is equipped with dome main body 4, and 2 lower end of screw head is equipped with anti-
Loosen lines 21, it is described it is antitheft screw card tooth 3 at least there are two, antitheft 3 cross section of card tooth that screws is triangle, institute
The antitheft card tooth 3 that screws stated includes stub end 31 and tail end 32, and the tail end 32 is concordant with screw head 2, the stub end 31
Direction it is contrary with screwing for stud 1, the center of the stud 1, screw head 2 and dome main body 4 on same axis,
