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

Embodiment 1

[0020] Such as Figure 1-Figure 4 As shown, the anti-theft seal structure of an electric energy meter described in this embodiment includes a watch case 4 and a watch body. The watch case 4 is provided with screw holes and screws 3 are inserted to fix the watch body, and the lower part is folded outward. The sealing cap 1 of the edge 9 is arranged above the screw 3, and the sealing cap 1 is covered with a metal ring 2, and the metal ring 2 is in contact with the outer flange 9, and the outer wall is provided with a plurality of buckles that are inclined outward and open upward. The buckle 6 is arranged circumferentially, and the inner wall of the watch case 4 above the screw hole is provided with an annular protrusion 5, and the buckle 6 is located below the annular protrusion 5 to form an undercut. The metal ring 2 has gaps to form a semi-surrounding structure. The sealing cap 1 is composed of a circular cap 7 and a plurality of arc-shaped plates 8 arranged on the edge of th...

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 seals, in particular to an anti-theft seal structure suitable for electric energy meters. Background technique [0002] At present, the components of the electric energy meter are usually installed in the watch body, and the watch body is tightly fastened to the watch case. The watch case and the watch body are fastened with screws, and the watch case and the screws are provided with through holes. Through the hole, then penetrate a lead seal block, and finally clamp the lead seal block with special sealing pliers to play the role of seal, anti-damage and anti-theft. 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 ...
