Abstract
The utility model discloses an anti-theft screw comprising a screw rod and a nut fixed at one end of the screw rod, wherein the nut is in a hemi-spherical shape or a conical shape, and more than two grooves are arranged on the surface of the nut. When the anti-theft screw is used, the anti-theft screw disclosed by the utility model is screwed by using a special wrench, and then the grooves on the nut are sealed by using rivets. When the anti-theft screw needs to be disassembled, the rivets are firstly opened by using a hand drill, and then the screw is disassembled by using the special wrench. The anti-theft screw has the following beneficial effects that: the condition that the screw is disassembled by a thieving person through using a common wrench or a pair of pipe pliers for stealing a transformer can be prevented by designing the nut of the screw into the hemi-spherical shape or the conical shape and using the nut of the screw on the transformer, so that the relative safety of the transformer is ensured, and the property safety of country and people is protected.
Description
Technical field
The utility model relates to a kind of screw, especially a kind of anti-theft screw that is used on the transformer.
Background technique
At present, the screw that on transformer, is equipped with all belongs to standard piece, and nut all is common hexagon nut or barrel nuts, though made things convenient for dismounting like this, can it be disassembled with common spanner or pipe wrench, and the theft accident also takes place easily.At present, domestic transformer theft accident frequently takes place, and causes very big loss for the country and people's property.Therefore press for a kind of screw that differs from common hexagon nut or barrel nut, make the offender will be difficult to disassemble screw, and then prevent the generation of transformer robbery accident with common spanner or pipe wrench.
The model utility content
The utility model technical problem to be solved provides a kind of screw with antitheft effect.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: a kind of anti-theft screw, comprise screw rod and the nut that is fixed on screw rod one end, and said nut is hemisphere or taper shape, on the surface of nut, is provided with plural groove.
Said groove be shaped as circle.
During use,, the described anti-theft screw of the utility model is tightened, with rivet the groove on the nut is shut then, when needing dismounting, open rivet with hand drill earlier, with special-purpose spanner screw is disassembled again with special-purpose spanner.
Adopt the beneficial effect that technique scheme produced to be: the utility model is designed to hemisphere or taper shape through the nut with screw; Be used on the transformer; The molecule that can avoid theft disassembles screw with common spanner or pipe wrench; Steal transformer, guaranteed the comparatively safe of transformer, protected the country and people's property safety.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model anti-theft screw;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the special spanner structural representation of the utility model anti-theft screw;
Fig. 4 is the worm's eye view of Fig. 3;
Wherein, 1, screw rod, 2, nut, 3, groove, 4, convexity.
Embodiment
Can know that like Fig. 1-embodiment shown in Figure 2 the described anti-theft screw of the utility model comprises screw rod 1 and the nut 2 that is fixed on screw rod 1 one ends, said nut 2 is hemisphere or taper shape, on the surface of nut 2, is provided with two circular grooves 3.
During use, with like Fig. 3-special spanner shown in Figure 4, the described anti-theft screw of the utility model is tightened, with rivet the groove on the nut is shut then, have on the special spanner with nut 2 on the suitable convexity of groove 3.When needing dismounting, at first rivet is opened, with special spanner the screw dismounting is being write then with hand drill.This anti-theft screw that is used on the transformer can prevent that the lawless person from common spanner dismounting screw, stealing transformer, has protected the country and people's property safety.
