Abstract
The utility model relates to that a kind of circular group is box-like anti-unloads anti-theft nut.Mainly solve existing anti-anti-problem of unloading anti-theft effect difference of unloading anti-theft nut.It is characterized in that: described nut (1) bottom is cylindrical body, cylindrical outer is equipped with outer ring (2), the cylindrical body top of described nut (1) is provided with boss (3), the external diameter of boss (3) is greater than outer ring (2) internal diameter, and being not more than the external diameter of outer ring (2), the upper surface of described boss (3) has several uniform grooves (4).This nut has easy for installation and anti-feature of unloading good anti-theft effect.
Description
Technical field
The utility model relates to a kind of axial lock compact form fastening piece, and a kind of circular group is box-like specifically prevents unloading anti-theft nut.
Background technique
Power circuit electric power pylon, railway, bridge are installed out of doors, are caused potential safety hazard sometimes by artificially removing.Conventional transverse direction locking is anti-unloads anti-theft fastening piece and generally adopts steel ball or steel column to lock, but nut use be not screwed into time steel ball or steel column easily by nut in come off, therefore, some anti-assembling nuts just do not reach and anti-ly unload anti-theft function.
Summary of the invention
In order to overcome existing anti-anti-deficiency of unloading anti-theft effect difference of unloading anti-theft nut, the utility model provides that a kind of circular group is box-like anti-ly unloads anti-theft nut, and this nut has easy for installation and anti-feature of unloading good anti-theft effect.
The technical solution of the utility model is: a kind of circular group is box-like prevents unloading anti-theft nut, comprise nut, it is cylindrical body bottom described nut, cylindrical outer is equipped with outer ring, the cylindrical body top of described nut is provided with boss, the external diameter of boss is greater than outer ring internal diameter, and is not more than the external diameter of outer ring, and the upper surface of described boss has several uniform grooves.
Gap is had between cylindrical body and outer ring bottom described nut.
The degree of depth of described groove is not less than 1mm.
Adhesive sticker is pasted with bottom described nut and outer ring.
The utility model has following beneficial effect: owing to taking such scheme, nut profile is adopted circular, and add a mobilizable outer ring, and the external diameter of outer ring is greater than boss external diameter, the outer ring rotating and nut can not rotate when turning like this, thus play and anti-ly unload anti-theft function.First nut hand is screwed to position during installation, then use special spanner to tighten up, because on nut, plane is provided with plane groove, special spanner is provided with plane groove equally, groove is between the two fitted mutually, non-slip when tightening, easy for installation.

Fig. 2 is the plan view of nut;
Fig. 3 is the sectional view of outer ring.
1-nut in figure, 2-outer ring, 3-boss, 4-groove, 5-adhesive sticker.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By shown in Fig. 1 to Fig. 3, a kind of circular group is box-like prevents unloading anti-theft nut, and comprise nut 1, be cylindrical body bottom described nut 1, cylindrical outer is equipped with outer ring 2, has gap between outer ring 2 and the cylindrical body of nut, makes free to rotate therebetween.The cylindrical body top of described nut 1 is provided with boss 3, and the external diameter of boss 3 is greater than outer ring 2 internal diameter, and is not more than the external diameter of outer ring 2, and namely the external diameter of boss 3 is less than or equal to outer ring 2 external diameter.Meanwhile, the height of outer ring 2 should be less than the cylindrical height of nut 1, and like this, when rotating outer ring 2, nut 1 can not together rotate thereupon.The upper surface of described boss 3 has several uniform grooves 4, and the bottom surface of groove 4 is inclined-plane, and its innermost degree of depth is not less than 1mm, and the most shallow place is concordant with boss 3 upper surface.Adopt special spanner when this nut is installed, special spanner has the groove matched with groove 4, when needs are tightened, special spanner is close to groove 4 and is tightened, and when thinking dismounting, special spanner rotates backward and can skid and cannot dismantle, play and prevent unloading anti-theft function.The inclined-plane of described plane groove 4 and the angle of boss 3 axis should be less than 80 °, prevent from skidding when tightening.
This nut, when assembling, is first picked up nut 1, is packed into outer ring 2 on the cylindrical body of nut 1 lower end, adhesive sticker 5 in stickup.In use, using pasting the one side of adhesive sticker 5 as supporting surface, being screwed into the bolt hand of dimension, then adopting special spanner to tighten, now movable outer ring 2 by shutoff on the lower end cylindrical body of nut 1.When dismantling, rotate outer ring 2 and nut 1 can not rotate, and the height of boss 3 is very little, cannot clamp to turn, thus plays and anti-ly unload antitheft effect.This nut fitting operation is convenient, has extremely strong anti-ly to unload anti-theft feature.
