Abstract
The utility model discloses an anti-theft nut to provide an anti-theft nut with simple structure and reliable anti-theft property. The anti-theft nut is characterized in that an external circumferential tapered wall (5C) of the nut is arranged at the external wall of the anti-theft nut (5); the external circumferential tapered wall (5C) of the nut is respectively provided with clockwise-clockwise force walls (5E) with a conjoined structure and a clockwise-anti-clockwise micro tapered slope (5F). In the process of installation and use, firstly, a screw (1) and the utility model (5) are fixed in the fixing hole of the corresponding object in series, and the screw top of the cement screw is propped in the angle wall of the clockwise-clockwise force walls (5E); then, the screw top of the cement screw is hammered by a hammer, etc. The threads of the anti-theft nut is forced and fastened along the clockwise-clockwise direction. The utility model makes use of the principle of the threads which can only be forced but not released, and thus the fasteners are prevented from being anti-theft. The utility model can be widely used for assembly the equipment or other components which are fixedly installed in the open air or easy theft sections with the functions of anti-theft and reinforcement.
Description
One, affiliated technical field
The utility model is that a kind of equipment or its parts that relate to being fixedly installed in outdoor easy robber location carry out the equipped fastening piece accessory of antitheft reinforcing.
Two, background technique
To ending at present, the existing objects such as electric power facility, the environmental protection facility in outdoor easy robber location and the building of decorateing that much are fixedly installed in are stolen, and it has caused harm and destruction in various degree to society and people.Use though there is in a small amount the non-standard component screw fastener carry out replacing before this,, promptly still do not miss according to stealing as long as the dress of imitated non-standard screw fastening piece, tear manual tool open.
Three, summary of the invention
At present situations that object is stolen and prior art is not enough such as the electric power facility that much is fixedly installed at present outdoor easy robber location, environmental protection facility and decoration buildings, provide a kind of being easy to install, adorn the back firmly, antitheft reliable the utility model technology.
The technological scheme that its technical problem that solves the utility model adopts is:
The utility model---anti-theft nut, comprise screw (1) and anti-theft nut (5), it is characterized in that: (5B), nut excircle tapered wall (5C), inner hole thread (5D) at the bottom of the nut top (5A) that is respectively equipped with linking body structure on the anti-theft nut (5), nut; On nut excircle tapered wall (5C), be respectively equipped with suitable clockwise direction degree of the urging wall (5E) and the contrary clockwise direction tapered external angle slope (5F) of linking body structure again; Nut excircle tapered wall (5C) is provided with recessed no protruding circumference tapered wall; Urge into along clockwise direction that wall (5E) is non-protruding shape vertical wall, its tapering is consistent with the tapering of nut excircle tapered wall (5C); Contrary clockwise direction tapered external angle slope (5F) is recessed shape tapered external angle slope.
The utility model is when implementing application is installed, elder generation packs screw (1) string that is provided with screw screw top excircle tapered wall (3) in the corresponding fixed hole, again the utility model anti-theft nut spinning on above-mentioned screw threaded stem (4), withstand along clockwise direction with cement ailing point etc. then and urge into wall (5E), and with hammer hammering cement screw top, force the nut screw thread to continue to urge into along clockwise direction, till it is fastening fully, the utility model is to utilize it can only urge the principle that into can not fall back, thereby makes all fastened things can both reach antitheft purpose.When meeting the utility model need change refitting the time, that just can only the electrification utensil, oxygen cuts through sand, mill, could remove after welding, cutting.
The beneficial effects of the utility model are: simple in structure, cheap, easy for installation, antitheft reliable, social benefit is obvious.
Four, description of drawings
Fig. 1 is the utility model structural drawing.Wherein (1) is screw, and (2) are the screw screw top, and (3) are screw screw top excircle tapered wall, (4) screw threaded stem, and (5) are anti-theft nut, (6) are fastened object.
Fig. 2 is the utility model anti-theft nut sectional view.Wherein (5) are anti-theft nut, (5A) are the nut top, (5B) are at the bottom of the nut, (5C) are nut excircle tapered wall, (5D) are inner hole thread, (5E) for urging into wall along clockwise direction, (5F) are contrary clockwise direction tapered external angle slope.
Five, embodiment
In Fig. 1, go up string at fastened object (6) and adorning screw (1); On screw (1), be respectively equipped with the screw screw top (2) and the screw threaded stem (4) of linking body structure; On screw screw top (2) outer wall, be provided with screw screw top excircle tapered wall (3); Go up spinning at screw threaded stem (4) and anti-theft nut (5).
In the embodiment shown in Figure 2, at the bottom of the nut top (5A) that is respectively equipped with linking body structure on the anti-theft nut (5), nut (5B); In anti-theft nut (5) endoporus, be provided with inner hole thread (5D); On the outer wall of anti-theft nut (5), be provided with nut excircle tapered wall (5C); The suitable clockwise direction that is respectively equipped with linking body structure on nut excircle tapered wall (5C) is urged into wall (5E) and contrary clockwise direction tapered external angle slope (5F).
Claims (4)
1, a kind of anti-theft nut comprises screw (1) and anti-theft nut (5), it is characterized in that: (5B), nut excircle tapered wall (5C), inner hole thread (5D) at the bottom of the nut top (5A) that is respectively equipped with disjunctor on the anti-theft nut (5), nut; The suitable clockwise direction that is respectively equipped with the disjunctor combination on nut excircle tapered wall (5C) is again urged into wall (5E) and contrary clockwise direction tapered external angle slope (5F).
2, anti-theft nut according to claim 1 is characterized in that: nut excircle tapered wall (5C) is for there being recessed no protruding circumference tapered wall.
3, anti-theft nut according to claim 1 is characterized in that: urge into along clockwise direction that wall (5E) is non-protruding shape vertical wall, and consistent with the tapering of nut excircle tapered wall (5C).
