Summary of the invention
The present invention mainly is that to solve existing in prior technology not enough, thereby develops a kind of lead seal structure of simple in structure, production efficiency is high, cost is low electric energy meter.
Above-mentioned technical matters of the present invention mainly is able to solve through following technical proposals: a kind of lead seal structure of electric energy meter is characterized in that: have base, with the lead sealing screw the two encapsulation is connected between loam cake, said base and loam cake; Said lead sealing screw comprises attachment screw and the lead seal structure that links to each other with screw.
Technical scheme of the present invention can also be further perfect:
As preferably, cover on said and be provided with cell body, said cell body bottom is provided with screw hole, and the lead sealing screw is arranged in the said screw hole.
As preferably, the head of said attachment screw has radial ringed groove.
As preferably, said lead seal structure comprises chuck, is connected the card post on the chuck; Be installed in the bar code-disc above the chuck, can place bar code in the bar code-disc, on the bar code-disc capping is arranged; There is bayonet socket said card post bottom, and said bayonet socket matches with the ring groove of attachment screw.
As preferably, the circular disk body of said chuck for matching with the cell body diameter of loam cake, disk body is provided with two or two above slotted holes, and the pitch-row of said slotted hole and attachment screw head diameter adapt.
As preferably, there is the coupler body that matches and be connected with the slotted hole of chuck the upper end of said card post, the lower end of said card post have with attachment screw on the bayonet socket that matches of ring groove, the end face of said bayonet socket has and is suitable for guiding bayonet socket to get into the inclined-plane of ring groove.
As preferably, a through hole is arranged in the middle of the said chuck.
The invention has the beneficial effects as follows: owing to covered cell body on according to the invention, said cell body bottom is provided with screw hole, and said lead sealing screw has ring groove; Said lead seal structure has bayonet arrangement, and said lead seal structure directly is pressed into cell body through the bayonet arrangement of blocking post and the lead sealing screw connects and fixes, and an opening is arranged in the middle of the said chuck; Can be used as the center of effort that destroys its structure, said code-disc internal memory put the lead sealing bar code, plays the function that prevents the bar table surface wear; The present invention does not adopt the higher lead sealing screw that has through wires hole of cost, does not adopt the complicated lead sealing line piercing process of lead sealing process, but adopts said lead seal structure to replace; Said lead seal structure is simple, can adopt the plastics manufacturing, and cost is low; And said lead sealing process is simple; Production efficiency is high, realizes automated production easily, so the present invention is simple in structure, production efficiency is high, cost is low.

Accompanying drawing 3 is electric energy meter superstructure synoptic diagram of Fig. 1;
Accompanying drawing 4 is a kind of lead seal structure synoptic diagram of the present invention;
Accompanying drawing 5 is expansion perspective view of Fig. 4;
Embodiment
Through embodiment and combine accompanying drawing, technical scheme of the present invention is further specified below.
Embodiment:
Like the lead seal structure of Fig. 2 electric energy meter shown in Figure 3, have base 2, be connected with loam cake 1 above the base 2; With lead sealing screw 3 the two encapsulation is connected between said base and loam cake; Said loam cake 1 is provided with cell body 11, and said cell body bottom is provided with screw hole 12, and lead sealing screw 3 is arranged in the said screw hole.
Shown in Figure 6 like Fig. 4, lead sealing screw 3 is combined with lead seal structure A on being connected it by attachment screw 6.The head of attachment screw 6 has radial ringed groove 61; Said lead seal structure A comprises chuck 8, is connected the card post 7 on the chuck, is installed in the bar code-disc 9 above the chuck, is placed with bar code in the bar code-disc, and capping 10 is arranged on the bar code-disc; The circular disk body of said chuck 8 for matching with cell body 11 diameters of loam cake 1 has through hole 81 in the middle of the disk body, is provided with four slotted holes 82 all around, and pitch-row between the said slotted hole and attachment screw 6 head diameters adapt; Said card post 7 has four; There is the coupler body 71 that matches and be connected with the slotted hole of chuck the upper end of card post; The lower end of said card post have with attachment screw on the bayonet socket 72 that matches of ring groove; The end face of said bayonet socket has 73, four the card posts 7 in inclined-plane that are suitable for guiding bayonet socket to get into ring groove to be respectively charged in four slotted holes 82 of chuck 8; The diameter and the chuck of said code-disc 9, capping 10 are consistent.
