Embodiment Construction

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Such as figure 1 - As shown in Fig. 4, a kind of electric energy meter body cover structure described in this embodiment includes an electric energy meter casing 1 and a flip cover 2, and the flip cover 2 is covered on the upper part of the casing 1, and the flip cover 2 has a through hole 5, and the metal part 4 with a slot is embedded on the surface of the housing 1 corresponding to the through hole 5. The upper part of the slot is an inverted stepped structure with a narrow outside and a wide inside. The bolt 3 with the buckle 9 at the tail passes through the through hole 5 and is engaged with the metal piece 4. The buckle 9 is fastened on the stepped surface of the slot. The head of the bolt 3 has a stepped structure and its steps Surface conflicts on the working surface of flip cover 2.

[0017] The entrance of the through hole 5 is provided with a step wit...

Abstract

An electric energy meter single enclosure structure designed according to the invention solves the technical problems of complex operation and low efficiency in the current electric energy meter enclosure. The structure comprises an electric energy meter shell and a flip cover, wherein the flip cover is engaged with the upper part of the shell in a covering manner and is provided with a through hole thereon, a metal piece with a slot is embedded on a surface where the shell is corresponding to the through hole, the upper part of the slot is a reverse step structure with narrow outside and wide inside, a bolt with a buckle on the tail thereof penetrates through the through hole to be in clamping connection with the metal piece, and the buckle is buckled on the step surface of the slot, and the head of the bolt adopts a step-shaped structure and the step surface thereof abuts against a working surface of the flip cover. The electric energy meter single enclosure structure can prevent the electric energy meter from being modified viciously during the use of the electric energy meter, and the bolt clamping connection structure is not exposed so as not to be restored after being destroyed, the sign representing that the electric energy meter is destroyed can be easily found, the destroyed electric energy meter can be replaced in time, and the anti-electricity theft effect is excellent.

Description

technical field [0001] The invention relates to an installation structure of an electric energy meter, in particular to an electric energy meter body cover structure. Background technique [0002] In order to ensure the safe and stable operation of the electric energy meter and accurate and reliable measurement, it is necessary to seal the qualified electric energy meter to prevent users from stealing electricity by means of parameter setting and hardware replacement of the electric energy meter. At present, the sealing forms of electric energy meters are all manually operated, and the main method is lead sealing. The specific operation process is as follows: first tighten the screws of the electric energy meter cover, then insert the copper wire through the through hole on the screw head and the two through holes on the cover, twist the two ends of the copper wire together and pass through the lead block, squeeze Press the lead weight so that the lead weight is closely con...
