Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, 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 utility model is mainly solved by following technical proposals: a kind of lead seal structure of electric energy meter, has base, be connected with loam cake above the base, it is characterized in that: there is the coupler body that matches and be connected with the slotted hole of chuck the upper end of described card post, there is the bayonet socket that matches with ring groove on the attachment screw lower end of described card post, and the end face of described bayonet socket has and is suitable for guiding bayonet socket to enter the inclined-plane of ring groove.
The technical solution of the utility model can also be further perfect:
As preferably, the head of described attachment screw has radial ringed groove.
As preferably, described 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 described card post bottom, and described bayonet socket matches with the ring groove of attachment screw.
As preferably, the circular disk body of described 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 described 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 described card post, and there is the bayonet socket that matches with ring groove on the attachment screw lower end of described card post, and the end face of described bayonet socket has and is suitable for guiding bayonet socket to enter the inclined-plane of ring groove.
As preferably, a through hole is arranged in the middle of the described chuck.
The beneficial effects of the utility model are: owing to covered cell body on described in the utility model, described cell body bottom is provided with screw hole, described lead sealing screw has ring groove, described lead seal structure has bayonet arrangement, described lead seal structure directly is pressed into cell body by the bayonet arrangement of blocking post and the lead sealing screw connects and fixes, one opening is arranged in the middle of the described chuck, can be used as the center of effort that destroys its structure, described the code-disc internal memory is put the lead sealing bar code, play the function that prevents the bar table surface wear, the utility model does not adopt the higher lead sealing screw that has through wires hole of cost, do not adopt the lead sealing line piercing process of lead sealing process complexity, but adopt described lead seal structure to replace, described lead seal structure is simple, can adopt the plastics manufacturing, cost is low, and described lead sealing process is simple, the production efficiency height, realize automated production easily, so the utility model is simple in structure, the production efficiency height, cost is low.
