In order to achieve the purpose, the invention provides a lithium battery cap which comprises a cap body, a sealing ring, a top cap, an elastic long piece, an elastic short piece and an aluminum piece, wherein the cap body is cylindrical, the upper bottom surface and the lower bottom surface of the cap body penetrate through the cap body, the cap body is tightly sleeved on the sealing ring, the upper end of the sealing ring is sleeved on the top cap, the middle end of the sealing ring is sleeved on the elastic long piece and the elastic short piece, the elastic short piece is positioned below the elastic long piece, and the lower end of the sealing ring is sleeved on the aluminum piece.
Preferably, the elastic long piece is provided with a cylindrical outer shape, and the bottom cover is positioned between the top cover and the elastic long piece.
Preferably, the top cover is cylindrical, the center of the top cover protrudes upwards to form a first spherical protrusion, and the edge of the top cover is welded with the cover body.
Preferably, the cross section of the sealing ring is in a shape of a mountain, the convex part at the middle end of the sealing ring is positioned between the elastic long piece and the aluminum piece, and the elastic short piece is positioned between the convex parts at the middle end of the sealing ring.
Preferably, the shapes of the aluminum sheet, the elastic long sheet and the elastic short sheet are cylinders, the center of the elastic short sheet protrudes downwards to form a spherical protrusion II, the center of the elastic long sheet protrudes downwards to form a spherical protrusion III, and the center of the aluminum sheet is provided with a through hole matched with the spherical protrusion II.
Preferably, the radius of the second spherical bulge is smaller than that of the third spherical bulge.
The invention achieves the following beneficial effects:
the elastic short piece acts on the elastic long piece through extrusion, so that the tightness of the whole device is enhanced, and meanwhile, the elastic short piece extrudes the convex part at the middle end of the sealing ring towards two sides, so that the sealing effect of the sealing device is enhanced; meanwhile, the elastic short sheet protects the aluminum sheet and prevents the aluminum sheet from being extruded for a long time to deform and fall off.
