Description
Technical field
The utility model relates to a kind of novel anti-theft nut.
Background technique
At present, various antitheft, the anti-assembling nut that are used on the power equipment mainly are divided into two classes, and a class is non-removable, slots on bolt, squeezes into permanent pin, and this class only is applicable to the new construction of line, and narrow limitation is big; Another kind of is the cover anti-assembling nut, and its anti-theft is generally poor.
Summary of the invention
Problem to be solved in the utility model is to propose good, the reusable novel anti-theft nut of a kind of theftproof performance at above-mentioned prior art.
The utility model is adopted solution to be by the problem of the above-mentioned proposition of solution: the novel anti-theft nut, its difference is to include fastening nut body, circular steel swivel nut and antitheft steel bushing, described circular steel swivel nut is arranged on antitheft steel bushing inside, and the circular steel swivel nut matches with fastening nut.
Press such scheme, one 90 ° of steps are arranged at described circular steel swivel nut top, and the middle part is provided with one and ends the rotary screw nail, and afterbody has the in-line fastening port, and fastening port one end embeds dismountable chock that only revolves.
Press such scheme, described antitheft steel bushing is provided with two antitheft holes, is inserted with antitheft pin on the antitheft hole, and the afterbody of antitheft steel bushing is provided with a circular scrobicular ring.
Earlier the circular steel swivel nut is tightened on the fastening nut during installation, will ends the rotary screw nail again and screw, and then antitheft steel bushing is enclosed within circular steel swivel nut and former fastening nut outside, on antitheft hole, plug antitheft pin at last.After installing, antitheft steel bushing has entangled former fastening nut, can't dismantle nut with spanner, and antitheft steel bushing is left rotation and right rotation only, can not seesaw.After with special tool antitheft pin being broken by force during dismounting, promptly desirable, dismantle antitheft steel bushing, remove with special tool again and end rotary screw nail and circular steel swivel nut, with conventional instrument fastening nut is removed at last.
Advantage of the present utility model:
1) this nut fastening or the dismounting all must use special tool, improved theftproof performance;
2) screw rod need not changed, and is supporting with the primary standard part, reusable;
3) under the condition of existing fastening nut, install this nut additional and can have the anti-loose anti-theft function, on-the-spot installation is very convenient;
4) can be used as on the antitheft communal facility of need such as transformer, iron tower, backguy handle, freeway guardrail, street lamp and use;
5) transformation of the way a little promptly can be used as fastening, anti-theft screw cap, removes fastening nut.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.
As shown in Figure 1.The utility model is a kind of novel anti-theft nut, its difference is to include fastening nut body 3, circular steel swivel nut 2 and antitheft steel bushing 6 are formed, described circular steel swivel nut is arranged on antitheft steel bushing inside, the circular steel swivel nut matches with fastening nut, one 90 ° of steps 4 are arranged at described circular steel swivel nut top, the middle part is provided with one and ends the rotary screw nail, afterbody has the in-line fastening port, fastening port one end embeds dismountable chock 7 that only revolves, described antitheft steel bushing is provided with two antitheft holes 5, be inserted with antitheft pin on the antitheft hole, the afterbody of antitheft steel bushing is provided with a circular scrobicular ring 1.Earlier the circular steel swivel nut is tightened on the fastening nut during installation, will ends the rotary screw nail again and screw, and then antitheft steel bushing is enclosed within circular steel swivel nut and former fastening nut outside, on antitheft hole, plug antitheft pin at last.After installing, antitheft steel bushing has entangled former fastening nut, can't dismantle nut with spanner, and antitheft steel bushing is left rotation and right rotation only, can not seesaw.After with special tool antitheft pin being broken by force during dismounting, promptly desirable, dismantle antitheft steel bushing, remove with special tool again and end rotary screw nail and circular steel swivel nut, with conventional instrument fastening nut is removed at last.
