The invention relates to the technical field of electric energy meters, in particular to an electricity larceny prevention electric energy meter which comprises a box body, a switch door, a first lock catch mechanism, a second lock catch mechanism and a linkage mechanism. A first positioning block and a second positioning block are mounted on the opening and closing door, and a first positioning groove and a second positioning groove are formed in the two positioning blocks respectively; the first lock catch mechanism comprises a telescopic rod, a connecting plate and an electric push rod, the electric push rod is connected with the telescopic rod through the connecting plate, and the telescopic rod is provided with a limiting plate corresponding to the first positioning groove; the linkage mechanism comprises a transmission rod, a first rack, a gear and a second rack, the first end of the transmission rod is hinged to the connecting plate, the second end of the transmission rod is hinged to the first rack, and the first rack is in transmission connection with the second rack through the gear; and the second lock catch mechanism comprises a pull rod and a hinge seat, the pull rod is hinged to the second rack, and a clamping block corresponding to the second positioning groove is arranged at the second end of the pull rod. The technical problem that in the prior art, the anti-theft effect is poor is effectively solved.
Description
technical field [0001] The application relates to the technical field of electric energy meters, in particular to an anti-theft electric energy meter. Background technique [0002] The electronic watt-hour meter samples the voltage and current of the user's power supply in real time, and uses a dedicated watt-hour meter integrated circuit to process the sampled voltage and current signals and multiply them to convert them into pulse outputs proportional to the electric energy. The display shows. [0003] The existing electric energy meter with anti-theft function is equipped with an alarm, although it can also play a certain role in anti-theft, but in the process of use, there will be situations where maintenance personnel accidentally touch the alarm during maintenance, and this phenomenon of accidental touch It is easy to happen, which will cause a certain degree of trouble to the maintenance personnel. And in the electric energy meter, part of the fasteners that are eff...
