Abstract
The utility model discloses an electricity-stealing preventing lead printing screw for an electric meter box, and relates to a screw. The lead printing screw comprises a cylinder (2) and a polished rod (4), and is characterized in that a cross slot (1) is formed in the upper end face of the cylinder (2), perforation holes (3) which run through two sides are formed in the cylinder (2), the lower end of the cylinder (2) is connected with the upper end of the polish rod (4), an diameter expanding external thread (6) is arranged at the lower part of the cylinder (2), and a groove (5) is formed in the upper part of one side of the external thread (6). The groove is formed in the external thread of the polish rod, and when the lead printing screw is mounted, a thin lead wire is simultaneously placed in the groove, the undetectable lead wire can be utilized to judge whether the electric meter box is touched by someone or not, so that the electric power department can discover stealing and prevent the stealing in time.
Description
[technical field]
The utility model relates to a kind of screw, especially relates to anti-electricity-theft lead stamp screw for a kind of electricity meter box.
[background technique]
Known, it is object that stealing just refers to illegally occupy electric energy, not hand over or to pay tariff less to realize and reduce life or entreprise cost, the means of stealing have multiple, a kind of is the current coil of changing short circuit measuring apparatus, normally inner at electric energy meter or outside with wire by current coil short circuit, more common way be with wire or and connecting resistance insert phase line input end and the output terminal of electric energy meter, play shunting action.Use wire short circuit, and conductor resistance is no better than zero, most electric currents will pass through from short circuit wire, and the current coil of electric energy meter does not almost have electric current, causes electric energy meter stall, so that this mode is easily found during due to surprise check is uncommon; Another kind is off voltage connection sheet or the divider resistance of connecting on potential winding.Off voltage coil makes potential winding decompression cause ammeter not turn exactly.Common methods is that the voltage plate of electric energy meter is unclamped, and this method needn't game clock be sealed, and belongs to more rudimentary stealing electricity method, and novel ordinary electric meter is at the inner short circuit connection of ammeter sheet; At present maximum is to open ammeter enclosing cover and lead sealing, be serially connected on potential winding with a resistance, then institute's series resistor is entangled to (having very high disguise) with insulating tape or spaghetti, its principle is to play dividing potential drop effect, a part of voltage is shared to resistance two ends, potential winding both end voltage is reduced, reach the object of few quantity calculation.This type of mode is also referred to as under-voltage method stealing; In view of the foregoing, the strike emphasis that under-voltage method stealing is power supply department; Especially along with the power consumption of enterprise increases, also rapid growth of the electricity charge that use, because the electricity charge increase very fast, some just become interested to stealing electricity, by ammeter is adjusted, to reaching the object of stealing, but electric energy is national wealth, rationally use and in accordance with regulations electricity payment be each user's obligation, stealing electric appearance has increased the input of country to electric power and the operation cost of power department undoubtedly, so take precautions against, to steal electricity be one of focus of power department.
[summary of the invention]
In order to overcome the deficiency in background technique, the utility model discloses anti-electricity-theft lead stamp screw for a kind of electricity meter box, by groove being set on the outside thread of polished rod, utilizes the galvanized wire that is difficult in groove to discover just can judge whether that someone moved.
For achieving the above object, the utility model adopts following technological scheme:
A kind of anti-electricity-theft lead stamp screw for electricity meter box, comprises cylinder, polished rod, is provided with cross recess in cylinder upper-end surface, described cylinder is provided with the perforation that connects both sides, the lower end of cylinder connects the upper end of polished rod, is provided with the outside thread of hole enlargement in the bottom of cylinder, is provided with groove at an externally threaded upper lateral part.
Anti-electricity-theft lead stamp screw for described electricity meter box, the described groove of outside thread one side is " U " shape groove.
Owing to adopting technological scheme as above, the utlity model has following beneficial effect:
Anti-electricity-theft lead stamp screw for electricity meter box described in the utility model,, by groove being set on the outside thread of polished rod, when the utility model is installed, in groove, synchronously put into a thin galvanized wire, utilize not for the galvanized wire of discovering just can judge whether that someone moved, be convenient to power department and find in time thief-proof; The utlity model has simple in structure, the advantage such as cost is lower, easy to use.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model;
In figure: 1, cross recess; 2, cylinder; 3, perforation; 4, polished rod; 5, groove; 6, outside thread.
[embodiment]
Can explain in more detail the utility model by the following examples, the utility model is not limited to the following examples;
Anti-electricity-theft lead stamp screw for electricity meter box described in 1 by reference to the accompanying drawings, comprise cylinder 2, polished rod 4, be provided with cross recess 1 in cylinder 2 upper-end surfaces, described cylinder 2 is provided with the perforation 3 that connects both sides, the lower end of cylinder 2 connects the upper end of polished rod 4, be provided with the outside thread 6 of hole enlargement in the bottom of cylinder 2, be provided with " U " shape groove 5 at a upper lateral part of outside thread 6.
Implement anti-electricity-theft lead stamp screw for electricity meter box described in the utility model, installing after ammeter, thin galvanized wire is incorporated in the groove 5 of outside thread 6, then tighten on the utility model and seal by the cross recess 1 on cylinder 2, in the time tabling look-up, observe position and the vestige of thin galvanized wire, once find that thin galvanized wire changes or comes off, just proving has people to move electric energy meter.
The utility model does not describe part in detail for prior art.
Claims (2)
1. an anti-electricity-theft lead stamp screw for electricity meter box, comprise cylinder (2), polished rod (4), it is characterized in that: be provided with cross recess (1) in cylinder (2) upper-end surface, described cylinder (2) is provided with the perforation (3) that connects both sides, the lower end of cylinder (2) connects the upper end of polished rod (4), the outside thread (6) that is provided with hole enlargement in the bottom of cylinder (2), is provided with groove (5) at a upper lateral part of outside thread (6).
