Abstract
The invention discloses an anti-theft screw. The anti-theft screw comprises a screw body and a plug. The screw body is in a cylindrical shape. An outer thread is arranged on the outer ring of the screw body. A groove is formed in the center of the top end of the screw body. The plug can be arranged in the groove in a plugging manner. The height of the plug is equal to the depth of the groove. By means of the manner, the situation that an electricity stealer easily unscrews the screw and steals electricity can be prevented.
Description
Technical field
The present invention relates to screw field, particularly relate to a kind of anti-theft screw.
Background technique
Adopt common screw to tighten in existing electricity meter box, power stealing person sneaks current after often electricity meter box can being opened.Ammeter can be caused like this to lose metering effect, cause power supply department economic loss.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of anti-theft screw, and can prevent power stealing person's screw of outwarding winding easily from sneaking current, this anti-theft screw structure is simple, easy to use.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of anti-theft screw, comprising: screw body and plug; Described screw body is cylinder type, and screw body outer ring is provided with outside thread, and the center on screw body top has groove; Described plug can block up and be located in groove, and plug height is equal with depth of groove.
Preferably, a segment distance is all left at described screw thread and the upper and lower two ends of screw body, and described threaded tip expands gradually to the screw body diameter on screw body top, and the screw body diameter of screw thread bottom to screw body bottom reduces gradually.
Preferably, described groove is yi word pattern.
The invention has the beneficial effects as follows: the present invention can prevent power stealing person's screw of outwarding winding easily from sneaking current.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of anti-theft screw one of the present invention preferred embodiment;
Fig. 2 is the decomposing schematic representation of a kind of anti-theft screw of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, screw body; 2, plug.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of anti-theft screw, comprising: screw body 1 and plug 2; Described screw body 1 is in cylinder type, screw body 1 outer ring is provided with outside thread, to screw in, thus be connected and fixed electricity meter box, the center on screw body 1 top has yi word pattern groove, screw-in anti-theft screw can be played by a word, can also by similar goods rotating theft-proof screws such as rulers, accommodation is extensive; Described plug 2 can block up and be located in groove, and plug 2 height is equal with depth of groove.When after screw-in anti-theft screw, in groove, block plug 2, sneaked current by screw of outwarding winding with anti-theft person.A segment distance is all left at described screw thread and screw body about 1 two ends, described threaded tip expands gradually to screw body 1 diameter on screw body 1 top, can prevent from too screwing in anti-theft screw, screw body 1 diameter of screw thread bottom to screw body 1 bottom reduces, gradually to screw in anti-theft screw.During use, rise with a word and screw in screw body 1, screw body 1 blocks plug 2, can realize anti-theft feature after screwing in groove.
The present invention can prevent power stealing person's screw of outwarding winding easily from sneaking current, and this anti-theft screw structure is simple, easy to use.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
