Description
Technical field
The utility model relates to the sealing device of electric energy meter, refers to a kind of three-phase electric energy meter seal especially.
Background technology
Electric energy meter seal is a kind ofly to prevent that unauthorized people from opening the device of electric energy meter, and it can prevent that unauthorized people from changing the electric energy meter structure or stealing is carried out in setting.The general lead-sheathing of tradition seal envelope and steel wire during use, pass the screw hole on the program design switch cover of three-phase electric energy meter, and clamp with lead with steel wire, prevent to open without permission electric energy meter program design switch cover.Prior art use lead sealing and and steel wire, have the deficiency of three aspects.One, the manual installation procedure of traditional seal is loaded down with trivial details, and installation effectiveness is low.Its two because traditional seal simple in structure is imitated easily, be easy to installation and removal, the poor-performing that it is antitheft.Its three, use plumbous to be material, big for environment pollution, and the installment work personnel contact lead for a long time, easily cause poisoning.Therefore, need a kind of electric energy meter seal, overcome the defective of prior art.
Summary of the invention
For addressing the above problem, the utility model provide a kind of simple and reliable for structure, be easy to install, anti-theft is good, compatibility is wide and the three-phase electric energy meter seal of environmental protection.
For achieving the above object, the technical solution of the utility model is: a kind of three-phase electric energy meter seal, and described three-phase electric energy meter seal comprises capping and base; Described base is provided with connecting portion, and the two ends of connecting portion are fixedly connected with the first tongue-and-groove seat and the second tongue-and-groove seat, and the described first tongue-and-groove seat and the second tongue-and-groove seat are respectively equipped with first tongue-and-groove and second tongue-and-groove towards the capping direction; All be provided with the card post on the described first tongue-and-groove seat one side relative with the second tongue-and-groove seat; Described capping is provided with cover plate, and described cover plate is provided with first trip and second trip towards the base direction; Corresponding first tongue-and-groove of described first trip, corresponding second tongue-and-groove of described second trip.This structure is owing to be provided with the card post, and the card post snaps in the seal hole of electric energy meter, and the electric energy meter program design switch cover of electric energy meter is sealed; Again the trip of capping is snapped in the tongue-and-groove of base, form a sealed whole body.After capping and base install, can also fix and base for supporting by welding or mode such as gluing, simultaneously in the effect of base portion pick-proof.This is simple and reliable for structure, makes things convenient for the installation personnel robotization to install; And anti-theft is good and compatible wide, and after seal installed, capping and base were a sealed whole body, and the non-electricity staff is difficult to pry open in unauthorized situation.
As specializing, described connecting portion is an open frame, and the described first tongue-and-groove seat and the second tongue-and-groove seat are separately fixed at the two ends, inside of open frame; The height of described open frame is greater than the height of the first tongue-and-groove seat and the second tongue-and-groove seat.Because the height of mouthful framework is greater than the height of the first tongue-and-groove seat and second tongue-and-groove, after capping covered, whole seal was an airtight rectangular parallelepiped, and this structure has improved the pick-proof performance.
As improvement, the top of the trip and second trip all is provided with cone boss, all is provided with a word groove at the center line of first trip and second trip; First tongue-and-groove all is provided with the accommodation space corresponding with cone boss with the low side of second tongue-and-groove.Owing to be provided with a cone boss and a word groove, when trip snapped in tongue-and-groove, the cone boss of trip was squeezed and is snapped in tongue-and-groove, and the cone boss of trip is replied prototype after entering accommodation space, and trip is fixed on tongue-and-groove.This structure is fixing solid, has further improved the pick-proof performance.
As improvement, cross rapid wear groove is arranged on the described cover plate.This structure makes things convenient for the staff to keep in repair and when electric energy meter is set, the dismounting and change seal.
As specializing, described capping and base are working of plastics.Because this seal is a working of plastics, has avoided the environmental pollution because of using lead to cause.
As improvement, described cover plate is provided with bar code or electronics radio frequency label.Owing to be provided with bar code or electronics radio frequency label, be convenient to realize wisdom management to electric energy meter.
