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 antitheft seal 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, penetrate a lead sealing piece again, clamp the lead sealing piece with special-purpose sealing pliers at last, play seal, tamper-proof and antitheft electro ultrafiltration.Though this seal mode has certain intensity, 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 the artificial destruction, antifalse effect is poor.
Summary of the invention
The objective of the invention is provides a kind of electric energy meter antitheft seal structure in order to solve above-mentioned the deficiencies in the prior art, does not have 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, the antitheft seal structure of a kind of electric energy meter that the present invention is designed, comprise watchcase and table body, have screw hole on the 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 the screw top, described sealing cap is with a quoit outward, described quoit is conflicted on the flanging outside and outer wall is provided with a plurality of cramps that make progress towards outer incline and opening, 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, earlier will be watchcase is affixed with the table body by screw, sealing cap and quoit constitute a single piece and are pressed into screw hole, and the cramp of quoit tips upside down on the annular protrusion, making sealing cap cover screw can not transfer to, form a protective cover, need open when operating, must destroy sealing cap earlier electric energy meter, cause the seal structure to restore, can find depredation at a glance, in time change ruined 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 been strengthened the intensity that back-off cooperates as metal material, and the pick-proof performance is good, but makes the also low slightly and material being convenient to process of working strength of sealing cap simultaneously; And seal is simple to operate, the production efficiency height.
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, makes things convenient for quoit to be inserted in outside the sealing cap.
Described sealing cap is made of a circular cap cover and a plurality of arcs that are 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 and kept out inside elastic bending when pushing, 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 height on the flanging of conflicting outside.
Described sealing cap is a plastic material, is convenient to processing, and cost is low.
Described cramp is square, and the lower end is fixed on the 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 bigger, and the more difficult quilt of sealing cap is transferred to, and further improves the pick-proof effect.
The antitheft seal structure of the electric energy meter that the present invention obtains, lock with the screw of showing body being used for fixing watchcase, and the quoit that screw and back-off are cooperated all is hidden in inside, difficult quilt is demolished, and as the need unpacking, then must adopt destructive procedure, can't restore to making the seal structure, can find depredation at a glance, in time change ruined electric energy meter, power-steeling preventing effect is good; Quoit has been strengthened the intensity that back-off cooperates as metal material, 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, the production efficiency height.
