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 the lower 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
The present invention relates to the seal technical field, especially a kind of theft-proof sealing structure that is applicable to electric energy meter.
Background technology
At present, usually the electric energy meter parts all are installed in the table body, the table body watchcase that linking closely outward, watchcase is fastening with table body Multipurpose screw, and watchcase and screw all have through hole, and lead sealing money passes above-mentioned through hole, then penetrate a lead sealing piece, clamp the lead sealing piece with special-purpose sealing pliers at last, play seal, tamper-proof and preventing fraudulent use of electricity effect.Although this seal mode has some strength, the lead sealing line will pass by envelope object and screw, and then unrolls and pass the lead sealing piece and clamp, and the threading complicated operation can only manual operations, can't robotization install seal additional; And outside the lead sealing line is exposed to, very easily replaced after artificial destruction, antifalse effect is poor.
Summary of the invention
The objective of the invention is provides a kind of electric energy meter theft prevention sealing structure in order to solve above-mentioned the deficiencies in the prior art, without complicated threading operation, be fit to automated production, and main seal structure is hidden in inside, and antifalse effect is good.
In order to achieve the above object, a kind of electric energy meter theft prevention sealing structure that the present invention is designed, comprise watchcase and table body, have screw hole on described watchcase and wear the affixed table body of screw, the sealing cap that it is characterized in that the outer flanging of a bottom band is arranged on above screw, described sealing cap overcoat has a quoit, described quoit is conflicted outside on flanging and outer wall is provided with a plurality of cramps towards outer incline and opening upwards, described cramp is circumferential setting, the watchcase inwall that is in screw hole top is provided with annular protrusion, and the below that described cramp is positioned at annular protrusion forms back-off.
During use, first will be by screw, that watchcase is affixed with the table body, sealing cap and quoit consist of a single piece and are pressed into screw hole, and the cramp of quoit tips upside down on annular protrusion, making sealing cap cover screw can not transfer to, form a protective cover, need to open when operating electric energy meter, must first destroy sealing cap, cause the seal structure to restore, can find at a glance depredation, in time change destroyed electric energy meter, improve electric energy meter pick-proof, anti-electricity-theft security; Sealing cap and quoit separate machined are assembled into a single piece again and compare and be machined directly to a single piece, process more convenient, and quoit has strengthened as metal material the intensity that back-off coordinates, and the pick-proof performance is good, but makes simultaneously the also slightly low and material being convenient to process of working strength of sealing cap; And seal is simple to operate, and production efficiency is high.
Improve and replenish as the further of said structure, the present invention also comprises the combination in any of following additional technical feature or these features:
Described quoit has breach and forms the semi-surrounding structure, facilitates quoit to be inserted in outside sealing cap.
Described sealing cap is made of a circular cap cover and a plurality of arcs of being arranged on the cap edge, and described arc lower end is provided with outer flanging, and when being pressed into screw hole, arc is met watchcase inside elastic bending when keeping out extruding, by more smooth and easy.
It is circumferentially uniform that described arc is, and described outer flanging is inclined upwardly, and conveniently is pressed into screw hole, and the quoit reliability of conflicting outside on flanging is high.
Described sealing cap is plastic material, is convenient to processing, and cost is low.
Described cramp is square, and the lower end is fixed on quoit, and the upper end is outward-dipping, and when sealing cap was made progress by external force, cramp outwards was out of shape, and the back-off area is larger, and the more difficult quilt of sealing cap is transferred to, and further improves the pick-proof effect.
The electric energy meter theft prevention sealing structure that the present invention obtains, watchcase locks with the screw of showing body to being used for fixedly, and the quoit of screw and back-off cooperation all is hidden in inside, difficult quilt is demolished, and as the need unpacking, must adopt destructive procedure, can't restore to making the seal structure, can find at a glance depredation, in time change destroyed electric energy meter, power-steeling preventing effect is good; Quoit has strengthened as metal material the intensity that back-off coordinates, and the pick-proof performance is good, also can reduce the intensity of sealing cap material simultaneously, convenient processing; And seal is simple to operate, and production efficiency is high.

Embodiment
The invention will be further described by reference to the accompanying drawings below by embodiment.
as Figure 1-Figure 4, a kind of electric energy meter theft prevention sealing structure that the present embodiment is described, comprise watchcase 4 and table body, have screw hole on described watchcase 4 and wear the affixed table body of screw 3, the sealing cap 1 of the outer flanging 9 of one bottom band is arranged on screw 3 tops, described sealing cap 1 overcoat has a quoit 2, described quoit 2 is conflicted outside on flanging 9 and outer wall is provided with a plurality of cramps 6 towards outer incline and opening upwards, described cramp 6 is circumferential setting, watchcase 4 inwalls that are in screw hole top are provided with annular protrusion 5, the below that described cramp 6 is positioned at annular protrusion 5 forms back-off.Described quoit 2 has breach and forms the semi-surrounding structure.Described sealing cap 1 is made of a circular cap cover 7 and a plurality of arcs 8 of being arranged on cap 7 edges, and described arc 8 lower ends are provided with outer flanging 9.Described arc 8 is circumferentially uniform, and described outer flanging 9 is inclined upwardly.Described sealing cap 1 is plastic material.Described cramp 6 is square, and the lower end is fixed on quoit 2, and the upper end is outward-dipping.
