Abstract
A sealing structure for a valve control lead-acid storage battery comprises a battery tank and a battery cover arranged on the top of the battery tank. The battery cover is provided with a pole column hole which is provided with a pole column. The sealing structure for the valve control lead-acid storage battery is characterized in that the pole column includes a pole column copper core. The outside of the pole column copper core is coated with a lead alloy. The outside of the lead alloy is coated with a covered plastic layer. The battery tank, the battery cover and the covered plastic layer are made from the same materials in injection molding mode. The covered plastic layer is in hot melting seal with the inner wall of the pole column hole. The battery tank is in hot melting seal with the battery cover. The pole column of the sealing structure for the valve control lead-acid storage battery is formed by the pole column copper core, the lead alloy and the covered plastic layer. The battery tank, the battery cover and the covered plastic layer are made from the same materials, thereby combining the battery tank, the battery cover and the covered plastic layer into a whole. The sealing portions have no obvious junction face, thereby avoiding the acid penetrating or acid leakage in long term usage.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction of battery, particularly a kind of hermetically-sealed construction of analysing valve control type lead-acid accumulator battery.
Background technology
At present, analysing valve control type lead-acid accumulator battery groove and battery cover material mainly contain two kinds: ABS and polypropylene.Adopt the battery of polypropylene battery case, battery cover, the general hot melt sealing means that adopts between battery case and the battery cover, sealing between battery cover and the pole is divided into two kinds, a kind of is pole and be embedded in the sealing of freezing of lead circle in the battery cover, and second kind be that the filling adhesive seals between pole and the battery cover.First kind of sealing means is because solder side can not be resisted the corrosion of sulfuric acid, and long-term use can be oozed acid; Because the polypropylene material glueability is poor, adopt the second method assembly process cycle long, pole oozes, leaks acid and can take place at any time.Adopt the battery of ABS battery case, battery cover, adopt adhesive sealing or hot melt sealing means between battery case and the battery cover, general employing sealing ring and adhesive sealing between battery cover and the pole.During long-term the use, pole is easily climbed acid, and it is unreliable to seal.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of above-mentioned defective that solved is provided, the sealing position does not have obvious faying face, and long-term use can not produce the analysing valve control type lead-acid accumulator battery hermetically-sealed construction that oozes acid or leak sour phenomenon.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of analysing valve control type lead-acid accumulator battery hermetically-sealed construction, comprise battery case and the battery cover that is positioned at the battery case top, have the pole hole on the battery cover, pole is equipped with pole in the hole, it is characterized in that: pole comprises pole copper core, the pole copper core outside is surrounded by lead alloy, the lead alloy outside is surrounded by covered plastics layer, battery case, battery cover and covered plastics layer adopt the same material injection moulding to make, covered plastics layer and pole hole inner wall hot melt involution, battery case and battery cover hot melt involution.
The encapsulating method of corresponding this hermetically-sealed construction is: a, employing same material (polypropylene plastics or ABS plastic) injection mo(u)lding battery case and battery cover; B, plastic processing is carried out at pole and battery cover sealing position, covered material is identical with the material of battery case and battery cover; C, use mould, to battery case, pole and battery cover sealing position heat fused, mould is warming up to uniform temperature (180 ℃～220 ℃ of polypropylene plastics, 280 ℃～320 ℃ of ABS plastic) time, to battery case, pole and battery cover sealing place heating 10s～20s, then that battery cover and pole, battery case is bonding, after cooling, remove clout.
Identical materials is adopted in battery case, battery cover and plastic processing, and battery cover and battery case, battery cover and pole three are become one, and the sealing position does not have obvious faying face, and long-term use can not produce oozes acid or leak sour phenomenon.
The beneficial effect that the utility model had is: the pole of analysing valve control type lead-acid accumulator battery hermetically-sealed construction is made up of pole copper core, lead alloy and covered plastics layer, battery case, battery cover and covered plastics layer adopt identical materials, battery cover and battery case, battery cover and pole three are become one, the sealing position does not have obvious faying face, and long-term use can not produce oozes acid or leak sour phenomenon.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, battery case; 2, battery cover; 3, pole hole; 4, pole copper core; 5, lead alloy; 6, covered plastics layer.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, battery cover 2 is positioned at battery case 1 top, have pole hole 3 on the battery cover 2, in the pole hole 3 pole is installed, pole comprises pole copper core 4, and pole copper core 4 outsides are surrounded by lead alloy 5, lead alloy 5 outsides are surrounded by covered plastics layer 6, battery case 1, battery cover 2 and covered plastics layer 6 adopt the same material injection moulding to make, covered plastics layer 6 and pole hole 3 inner wall hot melt involutions, battery case 1 and battery cover 2 hot melt involutions.
The encapsulating method of corresponding this hermetically-sealed construction is: adopt same material (polypropylene plastics or ABS plastic) injection mo(u)lding battery case 1 and battery cover 2; Pole and battery cover 2 sealing positions are carried out plastic processing, and covered material is identical with the material of battery case 1 and battery cover 2; Use mould, to battery case 1, pole and battery cover 2 sealing position heat fused, mould is warming up to uniform temperature (180 ℃～220 ℃ of polypropylene plastics, 280 ℃～320 ℃ of ABS plastic) time, to battery case 1, pole and battery cover 2 sealings place heating 10s～20s, then that battery cover 2 and pole, battery case 1 is bonding, after cooling, remove clout, the battery heat-sealing is finished.
