Description
Technical field
The utility model relates to a kind of high voltage iron tower anti-theft nut, specifically relates to a kind of anti-theft lock nut.
Background technique
Anti-theft nut is mainly used in carrying out anti-theft function to the device on high voltage iron tower.
Existing anti-theft nut forms primarily of the antitheft steel ball of the protection lasso outside nut and nut interior, and the anti-theft nut of this spline structure exists, and nut easily loosens, and cannot play fastening effect, installs complicated shortcoming.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned existing shortcoming, and the one provided has installs simply, and easy to use, nut can not loosen, the anti-theft lock nut of good anti-theft effect.
The technical solution of the utility model is achieved in that a kind of anti-theft lock nut, comprise nut body, it is characterized in that: described nut body is elongate structure, centre is provided with screw, nut body top is provided with lock nut, and described nut body upper end inner ring has the circular arc skewed slot coordinating lock nut, is provided with jam nut in the middle of described lock nut, outer ring, bottom has the locking arm of fit circular arc shape skewed slot, and described locking arm has groove.
Described circular arc skewed slot bottom and screw excessively smooth.
Further say: described groove is provided with 4-8.
In use: nut body is arranged on bolt fastening, at this moment lock nut is fastened on nut body top, the locking arm of the circular arc skewed slot on nut body and lock nut bottom is closely cooperated, due to locking arm having groove, when fastening by external force, make its locking arm distortion, be forever fastened on bolt, thus play the effect of anti-loose anti-theft.
The beneficial effects of the utility model are: a kind of anti-theft lock nut of this spline structure has to be installed simply, and easy to use, nut can not loosen, the advantage of good anti-theft effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, nut body 2, screw 3, lock nut 4, circular arc skewed slot 31, jam nut 32, locking arm 33, 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 lock nut, comprise nut body 1, it is characterized in that: described nut body 1 is in elongate structure, centre is provided with screw 2, nut body 1 top is provided with lock nut 3, and described nut body 1 upper end inner ring has the circular arc skewed slot 4 coordinating lock nut 3, is provided with jam nut 31 in the middle of described lock nut 3, outer ring, bottom has the locking arm 32 of fit circular arc shape skewed slot 4, and described locking arm 32 has groove 33.
Described circular arc skewed slot 4 bottom and screw 2 excessively smooth.
Further say: described groove 33 is provided with 4-8.
In use: nut body 1 is arranged on bolt fastening, at this moment lock nut 3 is fastened on nut body 1 top, circular arc skewed slot 4 on nut body 1 is closely cooperated with the locking arm 32 of lock nut 3 bottom, due to locking arm 32 having groove 33, when fastening by external force, its locking arm 32 is out of shape, is forever fastened on bolt, thus plays the effect of anti-loose anti-theft.
A kind of anti-theft lock nut of this spline structure has to be installed simply, and easy to use, nut can not loosen, the advantage of good anti-theft effect.
