Abstract
The utility model discloses an anti-prying lead seal structure of an electric energy meter. The anti-prying lead seal structure comprises a lead seal matched with a screw on a meter cover of the electric energy meter, wherein the lead seal comprises a casing; two grooves openings of which face to the opening direction of the casing are arranged on the outer side of the casing and a position at the outer side of the casing, which is close to the top surface, is provided with lug bosses; annular convex parts are arranged at the inner side of the casing along two ends of the two grooves; steps are arranged between the screw head and a threaded polish part of the screw on the meter cover; the screw head is provided with a plurality of threading holes; and the lead seal is made of plastic. The anti-prying lead seal structure disclosed by the utility model has the advantages of more environment-friendly and safe properties, convenience and firmness for mounting, stricter matching and difficulty in prying.
Description
Technical field
The utility model relates to the electronic instrument field, more particular it, the utility model relates to a kind of novel pick-proof lead seal structure of electric energy meter.
Background technology
Electric energy meter is the device that a kind of power consumption that is used for the user measures; And be used for confirming the expense that to pay with electric resources; But in use the user occurs and dismantle the electric energy meter watchcase privately for the stealing purpose through regular meeting; So that its back panel wiring or structure are changed, thereby cause public property loss and electric leakage dangerous.Though electric energy meter manufacturer also avoids the generation of this kind problem through several different methods at present, effect is also not obvious.
The utility model content
The utility model the utility model to be solved is intended to solve the defective that exists in the prior art, designs a kind of novel pick-proof lead seal structure of electric energy meter, has Environmental Safety more, and is easy for installation and firm, cooperate more tight, the advantage that difficult quilt is pried open.
For solving the problems of the technologies described above; The utility model adopts following technical scheme, and electric energy meter pick-proof lead seal structure comprises the lead sealing that matches with electric energy meter table lid screw; It is characterized in that: said lead sealing comprises sheath body; The said sheath body outside is provided with two grooves of opening towards the sheath body opening direction, and is provided with boss in the outside near the end face place, is provided with annular protrusion at two groove two ends, the inboard edge of said sheath body; Between the screw head of said table lid screw and screw thread polished rod portion, be provided with step, said screw head is provided with several through wires holes.
As preferably, said lead sealing is to be made up of plastics.
As preferably, said step is cylindrical.
As preferably, said sheath body top is cast with nameplate or sign.
As preferably; After in said table lid screw is packed the lead sealing screw hole of showing lid into and with the assembling of electric energy meter base, accomplishing; Said screw head is fixed in the table lid and covers the plane with table and has certain distance; After said lead sealing was inserted in table and cover screw, said annular teat and step were fixed, the end face of said sheath body with show to cover the plane and flush.
As preferably, boss is used for covering with table in said lead sealing makes groove and through wires hole secured in alignment when screw matches.
The beneficial effect of the utility model is significant:
It is plumbous as material to adopt plastics to replace, and prevents saturnism;
Compare the sealing device of prior art, easy for installation and firm, cooperate more tightly, difficult quilt is pried open, appearance looks elegant.
Description of drawings
Fig. 1 is the structural representation that the utility model is provided with the electric energy meter of lead sealing screw hole;
Fig. 2 is the lead seal structure synoptic diagram of the utility model;
Fig. 3 is the table lid bolt structure synoptic diagram of the utility model.
Embodiment
With reference to accompanying drawing, Fig. 1 shows the electric energy meter that is applicable to the utility model, and its table covers two ends and is provided with two lead sealing screw holes 10, and the table that is used to pack into covers screw.With reference to Fig. 2 and Fig. 3; The utility model electric energy meter pick-proof lead seal structure comprises sheath body 21 with the lead sealing that electric energy meter table lid screw matches; Sheath body 21 outsides are provided with two grooves 22 of opening towards the sheath body opening direction, and are provided with boss 24 in the outside near the end face place, are provided with annular protrusion 23 at two groove 22 two ends, sheath body 21 inboard edges; Cover at table to be provided with between screw head 31 and the screw thread polished rod portion 32 of screw and be preferably columniform step 33, screw head 31 is provided with four through wires holes 34.
As preferably, lead sealing is to be made up of plastics, also can be that other pollution-free sturdy material constitutes.
Be cast with nameplate or indicate 25 at sheath body 21 tops.
When table cover that screw is packed in the lead sealing screw hole 10 of table lid and with electric energy meter base assembling completion after; Screw head 31 is fixed in the table lid and covers the plane with table and has certain distance; With lead sealing be inserted in the table cover screw after; Annular teat 23 is fixed with step 33, and the end face of sheath body 21 covers the plane with table and flattens.Boss 24 is used in lead sealing and shows to cover making groove 22 and through wires hole 34 secured in alignment when screw matches.
More than be merely the preferred embodiment of the utility model, wherein the quantity of assembly or device is not for single, maybe be because enforcement need be for a plurality of.Should understand, the embodiment of the utility model is not to be the restriction to the utility model technical scheme, and all on this basis modifications, variation or substitute all should be covered by in the technological category that the utility model advocates.
