In zinc cylinder upper end insertion annular slot, the upper end of annular slot and zinc cylinder is interference fitted；By using this structure
Afterwards, the sealing effect between zinc cylinder and sealing ring body can be improved, and when positive electrode cap is pressed on sealing ring body, it can
Realize the secure support to sealing ring body.
The iron(-)clad battery sealing ring of the utility model, wherein, annular slot is in be oppositely arranged up and down with annular groove；This
After sample is set, during positive electrode cap is pressed on sealing ring body, zinc cylinder can realize the reliable branch to sealing ring body
Support.
The iron(-)clad battery sealing ring of the utility model, wherein, the vertical section of annular slot is inverted " v " shape shape structure；
After this structure, zinc cylinder upper end can realize the tight fit with annular slot, and can improve zinc cylinder and be inserted with annular
Sealing effect between slot, meanwhile, annular slot can be oriented to zinc cylinder upper end, and zinc cylinder upper end is facilitated to be embedded into annular and is inserted
In slot.
The utility model on the upper surface of sealing ring body by setting annular groove, the lower end of the positive electrode cap in battery
It can be embedded in annular groove, so, the air in external environment can be avoided to pass through positive electrode cap and sealing ring body
Between gap enter at carbon-point, without using fluid sealant, so, the appearance of contamination phenomenon can be avoided,
And production cost can be reduced, improve production efficiency.
