The utility model is achieved in that rotating sheet, includes the turning part and ring cylinder of stress upset, the annulated column
Body is formed at the middle part of turning part, and the ring cylinder extends upward to be longitudinally arranged, and the ring cylinder is arranged in a ring, its
Centre is surrounded formed with the centre bore being longitudinally arranged.
Further, the middle part of the lower surface of turning part is formed with annular lug prominent down.
Further, the top of the ring cylinder is formed with bearing surface, the flat arrangement of bearing surface.
Further, turning part is arranged in horizontal plane in bending.
Further, turning part, which has, forms in the ring cylinder periphery and the bending ring that is circular layout, described curved
Qu Huan is in curved arrangement in horizontal plane.
Further, the bending ring decurvation arrangement.
Further, the periphery of turning part is formed with the connecting portion being circular layout.
Further, the horizontal arrangement of the connecting portion.
Further, flat arrangement is distinguished in the upper surface of the connecting portion and lower surface.
The utility model additionally provides battery cap, including above-mentioned rotating sheet.
Compared with prior art, rotating sheet provided by the utility model, in the coping plate of battery cap, battery top
Lid is installed in the upper end open of the housing of battery, and when the pressure of inside battery is excessive, pressure acts on the turning part of rotating sheet
On, turning part is overturn upward, and ring cylinder is then moved upwardly by with the upset of turning part, and ring cylinder can then be connected to battery cap
Conducting strip on so that battery short circuit, avoid the enclosure interior pressure of battery from continuing to rise, due to ring cylinder shape cloth in a ring
Put, so, the appearance and size of ring cylinder can increase so that the area increase that ring cylinder abuts with conducting strip, and then avoid ring
Cylinder abuts phenomenon not in place with conducting strip.
