Background technique
Present electric energy meter seal system generally is the lead sealing formula, it is to be formed by the plumbous cap scolding tin of copper wire (copper wire and galvanized wire combination) with φ 15.5mm, with program switch lid crossed cylinder screw locking, then copper wire (copper wire and galvanized wire combination) is passed the through hole of program switch lid and crossed cylinder screw cap, then copper wire (copper wire and galvanized wire combination) two-end-point knot, fill in the plumbous cap groove position by the tight jail of clockwise button, last scolding tin is locked again.The shortcoming of above-mentioned lead sealing is: assembling is not easy in inspection table line to add the operation of automatic plastic packaging assembly production chain, can only manual assembly, and complicated operation, time-consuming feed consumption, cost is high, efficient is low.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ear envelope screw for the electric energy meter gauge stand is connected with loam cake, the enclosed construction that solves in the past can only manual assembly, and complicated operation, time-consuming feed consumption, cost are high, the problem of the low and bad realization automation assembling of efficient.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of for ear that the electric energy meter gauge stand is connected with loam cake envelope screw, and be placed on the screw hole place on described and extend and be provided with the preformed hole that inserts for described ear envelope screw; Described ear envelope screw comprises plug, metal screw and elastic ferrule, described metal screw is connected and composed by head and screw section, it is outer and extend upward and form accommodating cavity that described elastic ferrule is enclosed within the head of described metal screw, and described plug is installed in the described accommodating cavity; Be provided with snap-in structure between described plug and the elastic ferrule.During installation, at first utilize ear envelope screw that gauge stand and the loam cake of electric energy meter are connected and fixed, at this moment, metal screw and the elastic ferrule of ear envelope screw all place in the preformed hole; Then plug is put into the accommodating cavity of elastic ferrule; utilize the engagement connection between plug and the elastic ferrule that plug is fixed in the accommodating cavity of elastic ferrule; so; plug just can be with the head shadow of metal screw; the metal screw is played a very good protection; external force has no idea the metal screw is eased out and opens electric energy meter and carry out illegal operation, thereby reaches the seal function.
As improvement, described snap-in structure comprises the elastic card of being located at described elastic ferrule inwall and is located at and only blocks step on the described plug; Described elastic card places in the described accommodating cavity, described step and the described elastic card engagement connection of only blocking.
As improvement, a described side of only blocking step is tapered, and the step that only blocks of conical surface is conducive to snap in elastic card.
As improvement, describedly only block step ringwise.
As improvement, the top of described plug is provided with and stops step, and the described step bottom that stops offsets with described elastic ferrule top; The large size that stops the step top can the mint-mark sign.
As improvement, described elastic card and described elastic ferrule are formed in one.
As improvement, described plug top is provided with boss, is provided with the counterbore of installing for the RFID chip in the described boss.
The beneficial effect that the utility model compared with prior art brings is:
Utilize the engagement connection between plug and the elastic ferrule that plug is fixed in the accommodating cavity of elastic ferrule; so; plug just can be with the head shadow of metal screw; the metal screw is played a very good protection; external force has no idea the metal screw is eased out and opens electric energy meter and carry out illegal operation, thereby reaches the seal function.
