Description
Technical field
The utility model relates to a kind of high voltage iron tower nut, specifically relates to a kind of anti-theft nut.
Background technique
Anti-theft nut is difficult for stolen effect mainly for the protection of high voltage iron tower device; existing anti-theft nut is made up of nut body and restraining groove; nut body inside has a restraining groove, and spring is installed in restraining groove, and spring end is provided with steel ball; and nut body outer ring is provided with the prismatic structure of being convenient to installation; the anti-theft nut of this spline structure, because restraining groove is provided with one, and nut outer ring is provided with prismatic structure; exist anti-theft effect poor, nut is easily by the shortcoming of outside destroy.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned existing shortcoming, and the one providing has installs simply, easy to use, good anti-theft effect, and nut cannot be by the anti-theft nut of outside destroy.
The technical solution of the utility model is achieved in that a kind of anti-theft nut; comprise nut body; it is characterized in that: described nut body outer ring is provided with 3 for coordinating the positioning edge of machine tool fixture; inside has restraining groove; top is provided with protruding round platform, and described nut body outside is also overlapped a guard circle, and described guard circle and nut body connect together by two sided plaster glue; be convenient to transport, described sticking double faced adhesive tape is on nut body outer ring.
Described nut body inside has 3 and is ∠ shape structure restraining groove, and described restraining groove is evenly distributed on nut body inside, in described restraining groove, steel ball is installed.
Described round platform top has 3 pretension grooves that are ∠ shape structure, and described pretension groove is evenly distributed on round platform, and described pretension groove, by special tool, is installed nut.
In use, guard circle is enclosed within on nut body, steel ball is arranged in restraining groove; utilize pretension groove by special tool, nut is arranged on steel tower, when mounted; nut is rotated; steel ball is moved to restraining groove bosom, install, when dismounting; nut counterrotating; steel ball is moved to the most shallow place of restraining groove, thereby block screw mandrel, cannot dismantle.Because guard circle is to stick on nut body by two sided plaster, in the time rotating guard circle by external force, unaffected to nut body, thus realize anti-theft function.
The beneficial effects of the utility model are: a kind of anti-theft nut of this spline structure has to be installed simply, easy to use, good anti-theft effect, and nut cannot be by the advantage of outside destroy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, nut body 2, positioning edge 3, restraining groove 4, round platform 5, guard circle 6, two sided plaster 7, steel ball 8, pretension groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1: a kind of anti-theft nut; comprise nut body 1; it is characterized in that: described nut body 1 outer ring is provided with 3 for coordinating the positioning edge 2 of machine tool fixture; inside has restraining groove 3; top is provided with protruding round platform 4, and described nut body 1 outside is also overlapped a guard circle 5, and described guard circle 5 connects together by two sided plaster 6 glue with nut body 1; be convenient to transport, described two sided plaster 6 sticks on nut body 1 outer ring.
Described nut body 1 inside has 3 and is ∠ shape structure restraining groove 3, and described restraining groove 3 is evenly distributed on nut body 1 inside, in described restraining groove 3, steel ball 7 is installed.
Described round platform 4 tops have 3 pretension grooves 8 that are ∠ shape structure, and described pretension groove 8 is evenly distributed on round platform 4, and described pretension groove 8, by special tool, is installed nut.
In use, guard circle 5 is enclosed within on nut body 1, steel ball 7 is arranged in restraining groove 3; utilize pretension groove 8 by special tool, nut is arranged on steel tower, when mounted; nut is rotated; steel ball 7 is moved to restraining groove 3 bosoms, install, when dismounting; nut counterrotating; steel ball 7 is moved to restraining groove 3 the most shallow places, thereby block screw mandrel, cannot dismantle.Because guard circle 5 is to stick on nut body 1 by two sided plaster 6, in the time rotating guard circle 5 by external force, unaffected to nut body 1, thus realize anti-theft function.
A kind of anti-theft nut of this spline structure has to be installed simply, easy to use, good anti-theft effect, and nut cannot be by the advantage of outside destroy.
