Description
Technical field
The utility model relates to a kind of high voltage iron tower nut, specifically relates to a kind of fastening type anti-theft nut.
Background technique
Anti-theft nut is mainly for the protection of the not easily stolen effect 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 be provided with spring in restraining groove, spring end is provided with steel ball; and nut body outer ring is provided with the prismatic structure of being convenient to install; the anti-theft nut of this spline structure, because restraining groove is provided with one, and nut outer ring is provided with prismatic structure; there is anti-theft effect difference, 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 provided has installs simply, easy to use, and good anti-theft effect, nut cannot by the fastening type anti-theft nut of outside destroy.
The technical solution of the utility model is achieved in that a kind of fastening type anti-theft nut, comprise nut body, it is characterized in that: described nut body is made up of antitheft outer ring and circular theft-proof body, described antitheft outer ring is prismatic structure, centre is provided with the circular hole for installing circular theft-proof body, described circular hole lower lobes has a circle for the fastening piece of fastening circular theft-proof body, the described cylindrical structure of circular theft-proof body, centre is provided with screw, bottom, outer ring has the binding groove for matching fastener, antitheft groove is had in described screw, in described antitheft groove, spring and steel ball are installed.
Further say: described fastening piece is wedge shape pretension tooth, described binding groove is wedge shape pretension groove.
Further say: described wedge shape pretension tooth and wedge shape pretension groove are respectively provided with 3.
Further say: the stop collar being provided with matching fastener inside described binding groove, position-limiting action when playing fastening.
In use: circular theft-proof body is arranged on screw rod, again by antitheft outer ring sleeve on circular theft-proof body, at this moment wedge shape pretension tooth and wedge shape pretension slot fit, the prismatic structure on antitheft outer ring is utilized to rotate antitheft outer ring, make its wedge shape pretension cingulum move wedge shape pretension groove to rotate, thus circular theft-proof body is arranged on screw rod, the spring in antitheft groove and steel ball is utilized to play anti-theft function, because wedge shape pretension tooth and wedge shape pretension groove are wedge shape, make circular theft-proof body can only be fastening, cannot dismantle, thus play the effect that external force cannot dismantle.
The beneficial effects of the utility model are: a kind of fastening type anti-theft nut of this spline structure has to be installed simply, and easy to use, good anti-theft effect, nut cannot by the advantage of outside destroy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, nut body 2, antitheft outer ring 3, circular theft-proof body 4, circular hole 5, fastening piece 6, screw 7, binding groove 8, antitheft groove 51, wedge shape pretension tooth 71, wedge shape pretension groove 9, stop collar.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1: a kind of fastening type anti-theft nut, comprise nut body 1, it is characterized in that: described nut body 1 is made up of antitheft outer ring 2 and circular theft-proof body 3, described antitheft outer ring 2 is in prismatic structure, centre is provided with the circular hole 4 for installing circular theft-proof body 3, described circular hole 4 lower lobes has a circle for the fastening piece 5 of fastening circular theft-proof body 3, the described cylindrical structure of circular theft-proof body 3, centre is provided with screw 6, bottom, outer ring has the binding groove 7 for matching fastener 5, antitheft groove 8 is had in described screw 6, in described antitheft groove 8, spring and steel ball are installed.
Further say: described fastening piece 5 is wedge shape pretension tooth 51, and described binding groove 7 is wedge shape pretension groove 71.
Further say: described wedge shape pretension tooth 51 and wedge shape pretension groove 71 are respectively provided with 3.
Further say: the stop collar 9 being provided with matching fastener 5 inside described binding groove 7, position-limiting action when playing fastening.
In use: circular theft-proof body 3 is arranged on screw rod, again antitheft outer ring 2 is enclosed within circular theft-proof body 3, at this moment wedge shape pretension tooth 51 coordinates with wedge shape pretension groove 71, the prismatic structure on antitheft outer ring 2 is utilized to rotate antitheft outer ring 2, its wedge shape pretension tooth 51 is made to drive wedge shape pretension groove 71 to rotate, thus circular theft-proof body 3 is arranged on screw rod, the spring in antitheft groove 8 and steel ball is utilized to play anti-theft function, because wedge shape pretension tooth 51 and wedge shape pretension groove 71 are in wedge shape, make circular theft-proof body 3 can only be fastening, cannot dismantle, thus play the effect that external force cannot dismantle.
A kind of fastening type anti-theft nut of this spline structure has to be installed simply, and easy to use, good anti-theft effect, nut cannot by the advantage of outside destroy.
