Electric energy meter theft prevention sealing structure

Abstract

The invention designs an electric energy meter theft prevention sealing structure which solves the technical problem of low productivity because the traditional electric energy meter seal is still manually operated. The electric energy meter theft prevention sealing structure comprises a meter shell and a meter body, wherein the meter shell is provided with a screw hole, and a screw is fixedly connected with the meter body after penetrating through the screw hole. The electric energy meter theft prevention sealing structure is characterized in that a seal cap with an outer folding edge at thelower part is arranged on the screw; a metal ring is sleeved outside the seal cap; the metal ring is abutted against the outer folding edge, and the outer wall is provided with a plurality of buckling pieces which are outwards inclined and opened to the upper part; the buckling pieces are circumferentially arranged; the inner wall of the surface shell arranged at the upper part of the screw hole is provided with an annular projection; and the buckling pieces are positioned at the lower part of the annular projection to form inversed buckling. The invention can visually find out damage traces and replace the damaged electric energy meter in time and has the advantages of good electricity theft prevention effect, high inversed buckling matching strength, good pickproof performance, convenience in processing, simplicity in sealing operation and high productivity.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to an anti-theft sealing structure suitable for an electric energy meter. Background technique [0002] At present, the parts of the electric energy meter are usually installed in the watch body, and the watch case is tightly fastened to the outside of the watch body. A lead seal block is inserted into the through hole, and finally the lead seal block is clamped with a special sealing pliers, which plays the role of sealing, anti-damage and anti-theft electricity. Although this sealing method has a certain strength, the lead sealing wire has to pass through the sealed object and the screw, and then go around and pass through the lead sealing block for clamping. The lead sealing wire is exposed and can easily be replaced after being destroyed by humans, and the anti-counterfeiting effect is poor. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provid...

AI Technical Summary

Problems solved by technology

Although this sealing method has a certain strength, the lead sealing wire must pass through the sealed object and the screw, and then go back and pass through the lead seal block for clamping. The threading operation is complicated and can only be operated manually, and the seal cannot be automatically installed; and The lead seal wire is exposed, it is easy to be replaced after artificial damage, and the anti-counterfeiting effect is poor
