Abstract
The utility model relates to a steel shell battery seal structure, particularly a seal insulation structure for an alkaline steel shell square battery. The steel shell battery seal structure comprises a battery cover and a pole. The utility model is characterized in that a pole insulation sleeve is sheathed on the pole; a grooved O ring and a lower insulation ring are sequentially arranged between the pole and the bottom of the battery cover from inside to outside; an upper insulation ring is arranged between the pole and the battery cover; the inner side and outer side of the grooved O ring are respectively provided with an annular groove; and the outer side of the pole insulation sleeve and the inner side of the lower insulation ring are respectively provided with bulges corresponding to the grooves. Due to the adoption of the grooved O ring, the grooved surfaces are respectively embedded into the lower insulation ring and the pole insulation sleeve; when the outer nut is fastened, the compression of the grooved O ring can ensure the sealability of the battery; and due to the arrangement of the upper insulation ring and the lower insulation ring, the seal effect is enhanced. The utility model has the advantages of simple structure, small size, and favorable seal and insulation effects, and enhances the assembly reliability of the battery.
Description
Technical field
The utility model relates to a kind of steel shell battery sealing structure, particularly a kind of seal insulation structure for electrothermal that is applicable to basic steel shell side shape battery.
Background technology
At present, the steel shell battery sealing structure generally has double sealing structure and single hermetically-sealed construction, the double sealing structure complex structure, and volume is larger, and reliability is relatively poor, and battery is crossed and is climbed the alkali phenomenon in the use procedure; Although single hermetically-sealed construction is simple, effect is better, lacks anti-polar-column rotation structure, and when the pole outer nut was fastening, pole can produce very large torsion, caused easily pole and lug sealing-off.
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 defects that solved is provided, can effectively realizes the steel shell battery sealing structure of the insulated enclosure between cell sealing and pole and the box hat.
The technical scheme that its technical problem that solves the utility model adopts is: described steel shell battery sealing structure, comprise battery cover and pole, it is characterized in that: be socketed with the pole insulating case on the pole, be disposed with from inside to outside fluting O shape circle and lower insulated ring between the bottom of pole and battery cover, be provided with insulated ring between the top of pole and battery cover, inboard and the outside of fluting O shape circle have a circle groove, and the inboard of the outside of pole insulating case and lower insulated ring is respectively arranged with the projection corresponding with groove.
The top of described battery cover is provided with draw-in groove, and the bottom correspondence of upper insulated ring is provided with fixture block.
The bottom of described battery cover is provided with projection, and the top correspondence of lower insulated ring is provided with recessed groove.
The bottom of battery cover has projection, top that draw-in groove is arranged, and is used with the recessed groove of lower insulated ring and the fixture block of upper insulated ring, has prevented that the torsion of generation when external nut is fastening is to the damage of lug and pole junction.
The inboard of described battery cover is provided with groove of a circle, and fluting O shape circle is positioned at down in the groove.
The beneficial effect that the utility model has is: the steel shell battery sealing structure is owing to adopted fluting O shape circle, its fluting face simultaneously embeds on the lower insulated ring, another side embeds in the pole insulating case, and when outer nut was fastening, the compression of fluting O shape circle can guarantee that battery is sealed, be provided with insulated ring and lower insulated ring, improved sealing effectiveness, simple in structure, volume is little, sealing and insulation effect are good, have improved the reliability of battery assembling.
