Abstract
Anti -theft electric screw, including the screw pole, still include one side with the screw pole is connected, the edge outstanding in the circular ka tai of screw pole, set up in circular card platform opposite side is through twisting into two parts the cap nut of being connected with circular ka tai, the cap nut surface be equipped with and be used for the recess screwed, the lateral wall of this recess be vertical side wall along clockwise, along anticlockwise for the lateral wall that inclines. Through the utility model discloses can solve among the prior art and to loosen the screw division board from the element cell of being qualified for the next round of competitions and steal the defect of launching the electricity toward the measurement unit, the recess of cap nut makes the screw to screw up can not to unscrew, and screw after screwing up can be twisted off the cap nut along with twisting off, prevents that the screw from being unloaded.
Description
Technical field
This utility model belongs to the anti-theft electricity technology field of power system, particularly relates to anti-electricity-theft screw.
Background technology
In current batch meter, power administration is unfinished avoids stealing electricity phenomenon, it is desirable to the shell structure that each complete producer uses to have anti-electricity-theft requirement.Current batch meter is divided into wire inlet unit, outgoing line unit and metering units.Metering units is to adopt lead sealing screw lead sealing will not directly be opened stealing.But case is interior or in cabinet, three unit are intercommunications or adopt screw stationary barrier to split.Some user, in order to reduce electricity cost, often from outgoing line unit room directly or unclamp screw demarcation strip toward the tampered electricity consumption of metering units, utilizes table tail screw by short circuit current or off voltage circuit, causes certain economic loss to electric industry unit.For effectively preventing from utilizing aforesaid way stealing, a kind of electrical energy meter anti-theft electricity screw of design, is be presently required to solve the technical problem that.
Summary of the invention
The purpose of this utility model is in that, overcomes the deficiencies in the prior art, it is provided that a kind of anti-electricity-theft screw, it is possible to solve to unclamp in prior art the screw demarcation strip defect toward the tampered electricity consumption of metering units from outgoing line unit room.
For solving above-mentioned technical problem, the technical solution of the utility model is: anti-electricity-theft screw, including lead screw, also include that side is connected with described lead screw, edge protrudes from the circular chuck of described lead screw, it is arranged at described circular chuck opposite side by twisting into two parts the cap nut that part is connected with circular chuck, described cap nut surface is provided with the groove for screwing, and the sidewall of this groove is vertical sidewall along clockwise direction, is sloped sidewall in the counterclockwise direction.
Preferably, described in twist into two parts part be cylinder, its diameter radius more than lead screw and the diameter less than lead screw.When lead screw is submerged installing hole, when circular chuck touches installed surface, continue firmly the turn of the screw and can twist into two parts part, it is prevented that electricity filching person opens power equipment without authorization.
Preferably, the length twisting into two parts part described in is 2-4mm.Arrange the length twisting into two parts part to be conducive to controlling cost, save material.
The beneficial effects of the utility model are: due to the end of lead screw be fixed with one can twist into two parts twist into two parts part, twist into two parts the fixing connecting screw cap of part, so facilitate the assembly manipulation of client, improve efficiency of assembling, reduce cost, cap nut groove is vertical sidewall along clockwise direction, it is sloped sidewall in the counterclockwise direction, make to tighten screw can not unscrew, it is prevented that twist into two parts when part does not break and still can unload screw stealing by cap nut.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
Embodiment 1:
nullAnti-electricity-theft screw，Including lead screw 6，Also include side to be connected with described lead screw 6、Edge protrudes from the circular chuck 5 of described lead screw 6，It is arranged at described circular chuck 5 opposite side and twists into two parts, by cylinder, the cap nut 3 that part 4 is connected with circular chuck 5，Described cap nut 3 surface is provided with the groove 7 for screwing,Described groove is yi word pattern groove，The sidewall of this groove 7 is vertical sidewall 2 along clockwise direction,It is sloped sidewall 1 in the counterclockwise direction，The angle of inclination of described inclined side 1 can be 45 ° to 60 °，This utility model adopts 60 °，The described diameter half more than described lead screw 6 diameter twisting into two parts part 4，Described cylinder twists into two parts the half that the diameter of part 4 is described lead screw 6 external diameter，Length is 3mm，Described circular card,The diameter 5mm bigger than the external diameter of described lead screw 6 of 5.
During installation, first the anti-electricity-theft screw of normal rotation submerges in installing hole completely to lead screw 6, circular chuck 5 is stuck on installed surface because being relatively large in diameter, now more firmly to installation direction rotation screw cap 3, cylinder is twisted into two parts part 4 and is relatively carefully first twisted into two parts because of diameter, now anti-electricity-theft screw loses cap nut 3, it is impossible to be disassembled again, namely completes to install.Do not twisted into two parts for preventing from twisting into two parts part 4, cap nut 3 is vertical sidewall 2 for groove 1 sidewall screwed along clockwise direction, it is sloped sidewall 1 in the counterclockwise direction, so make setter or electricity filching person can only tighten screw and cannot unscrew, further ensure power equipment not to be destroyed, place stealing and occur.
Embodiment 2:
Anti-electricity-theft screw, including lead screw 6, also include that side is connected with described lead screw 6, edge protrudes from the circular chuck 5 of described lead screw 6, it is arranged at described circular chuck 5 opposite side and twists into two parts, by cylinder, the cap nut 3 that part 4 is connected with circular chuck 5, described cap nut 3 surface is provided with the groove 7 for screwing, and described groove 7 is cruciform groove.
Embodiment described in the utility model is only the description that preferred implementation of the present utility model is carried out; not this utility model design and scope are defined; under the premise without departing from this utility model design philosophy; various modification that in this area, the technical solution of the utility model is made by engineers and technicians and improvement; protection domain of the present utility model all should be fallen into; the technology contents that this utility model is claimed, all records in detail in the claims.
