An inner cover and an outer cover are arranged on the outer side of the motor part; wherein, the outer cover is sleeved on the outer side of the inner cover. The utility model provides the thief proof electricity meter which has very huge temper resistant function and facilitates the motor to be resistant against ferromagnetic interference through two layers of screening covers. The utility model overcomes the shortcomings of the prior art, and the shortcomings are that the user can unclench a meter cover to steal the electricity or facilitates the meter cover to reversely be rotated or stop rotation by the utilization of the ferromagnetic substance to interfere the motor so as to reach the object of stealing the electricity.
Description
Technical field
The utility model relates to a kind of electric energy register, the anti-electricity-theft register of especially a kind of electromechanical.
Background technology
Present user is multipurpose electronic formula electric energy register when electric energy metrical, because stealing user means are varied at present, show that prying open the table capping plug on the electromechanical list rate register advances group character wheel stealing of thin slice, adopt strong magnet to disturb step motor driven stealing etc., the stealing problem is perplexing power supply department always, existing electromechanical register exists a little less than the anti-stealing electricity function, the user can pry open table covers stealing, or with strong magnetic interference motor, make its reversing or stall, to reach the stealing purpose.
Summary of the invention
The purpose of this utility model is the weak point that overcomes existing electronic electric energy meter, a kind of very strong tamper-resistant function that has is provided, and makes motor can resist the anti-electricity-theft register of strong magnetic interference by the multilayer screen cover.
The purpose of this utility model is achieved in that and includes character wheel parts, reducer casing parts, motor part etc., and described character wheel parts are installed on the framework, and described framework is provided with Tamper Cover, and described motor part is provided with one deck radome at least.
Described framework side is equipped with support, and the reducer casing parts are sleeved in the support, is fixed with motor part on the support, and described radome is sleeved on outside the motor part and is fixed on the support.
Described radome is made up of inner cover and outer cover, and inner cover is sleeved on outside the motor and is fixed on the support, and outer cover is enclosed within on the inner cover.
Described inner cover and outer cover are provided with unthreaded hole.
Described radome is made up of inner cover and outer cover, and the bottom surface of inner cover is fixed on the support, and described motor is installed in inboard, inner cover bottom surface, and the outer cover cover is buckled on the inner cover.
Described inner cover is provided with motor fixed orifice and unthreaded hole, and outer cover is provided with unthreaded hole.
Described Tamper Cover is a translucent cover, is fastened on the framework.
Described outer cover is fastened on the inner cover, and outer cover is fixed together by bolt and inner cover.
Described outer cover and inner cover are riveted together.
Described Tamper Cover is provided with dop or groove.
Because the utility model has adopted said structure, compared with prior art has the following advantages: have tamper-resistant function, owing on the character wheel parts, be covered with Tamper Cover, so the user can't dial the character wheel stealing; The motor external seal has the multilayer screen cover, can reach anti-magnetic field interference function fully, and further shielding strong magnetic field effectively makes the register motor not be subjected to the interference in any magnetic field; Because motor is not subjected to any magnetic interference, institute is so that motor driven moment obviously strengthens, and character wheel group card word probability obviously reduces; The utility model is applicable to the meter degree device of various electronic electric energy meters.

Embodiment
The anti-electricity-theft register of electromechanical of the present utility model can have following several scheme during fabrication: only install one deck radome 6 additional in motor part 3 outsides, but its to the screening ability in magnetic field a little less than, have only about 800 Gausses, can't shield high-intensity magnetic field.Can also install two layers of radome 6 in motor part 3 outsides additional, this moment, radome 6 was made up of inner cover 8 and outer cover 9, and described outer cover 9 can be fastened on the inner cover 8, and outer cover 9 can also be fixed together by bolt or riveted joint and inner cover 8.Its screening ability to magnetic field obviously strengthens, and can reach more than 5000 Gausses, has played the function of armoured magnetic field really.More than two kinds of structures can only be protected utilizing the magnetic field stealing; pry open the table lid as electricity filching person and fall to dial character wheel; just can't take precautions against; so also when motor part 3 outsides install radome 6 additional; on the framework 4 that character wheel parts 1 are installed, install Tamper Cover 5 additional; wherein Tamper Cover 5 is a translucent cover, is made by the highstrenghtpiston, and it is fastened on the framework 4 by dop on it or groove.
Its principle of work is as follows: when register uses, when the pulse signal of outside is imported the coil of motor part 3, under the air-gap field effect of straight iron core and bending iron core composition, magnet steel and promptly do 180 degree steppings rotations with axle and motor tooth that it links, the motor tooth drives the gear set rotation of reducer casing parts 2 simultaneously, train of reduction gears drives the first run rotation of character wheel parts 1 again, and the first run is revolved to turn around and can be driven rounding wheel rotation 1/10 circle like this, thereby plays the effect of electric energy counter.Tamper Cover 5 is stuck on the framework 4 character wheel parts 1 is all covered in addition, makes electricity filching person can't contact character wheel parts 1, reaches pick-proof stealing function, makes because of Tamper Cover 5 usefulness highstrenghtpiston transparent materials, does not read numeral so can not influence the user.Simultaneously inner cover 8 and outer cover 9 are installed motor part 3 double layer screens in the outside of motor part 3, can more effectively shield the interference of external electromagnetic field to motor part 3, its diamagnetic field energy power is more than 5000 Gausses, wherein have three motor fixed orifices 11 and two unthreaded holes 10 on the inner cover 8, have two unthreaded holes 10 on the outer cover 9, motor part 3 is fixed in the inner cover 8 by bolt and three motor fixed orifices 11.Outer cover 9 and inner cover 8 are riveted together, and inner cover 8 connects as one by the screw on unthreaded hole 10 and the support 7.
