[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated.
Embodiment one: shown in Fig. 1-4, the high leakproofness lithium-ion-power cell that double end is drawn pole comprises battery case shell 4, two of battery case shell 4 is integrally formed anodal pressure cover 2, negative pole pressure cover 14 respectively, Positive Poles 3 is established at the middle part of anodal pressure cover 2, and negative pole aluminium pole 11 is established at the middle part of negative pole pressure cover 14.
Safety valve 1 is the bottle cap shape, and according to its cross section, one-body molded by top board 11, sidewall 12 and interior ring 13, the medial surface of sidewall 12 forms annular groove 14 one, the following inwall of annular groove 14 and the overhead kick of interior ring 22 thorn 25 overlap joints.Interior ring 13 is in the inside of safety valve 1, and with sidewall 12 concentrics, 12 of interior ring 13 and sidewalls leave gap 15, insert sealing ring 16 in the gap 15.
The sidewall 12 of safety valve 1 stretches in the cannelure 21 of pressure cover 2, and the interior ring 22 of pressure cover 2 stretches in the gap 15 of safety valve 1, and ring 22 tops and top board were 11 in sealing ring 16 was in.
