Can more successfully open-top fluid sealant so that the air inside zinc cylinder is discharged from through hole, play the role of battery anti-explosion；This
The hole of a size, while can prevent that fluid sealant is rushed to open battery, causes poor sealing in assembling process.
The interior plug battery with blast resistance construction of the utility model, wherein, it is provided on the upper surface of sealing ring for just
The annular groove of the annular nib insertion of polar cap lower end, the outer edge card for annular nib is provided on the side wall of annular groove
The annular slot entered；After this structure, the fix tightly soundness between positive electrode cap and sealing ring can be improved.
The interior plug battery with blast resistance construction of the utility model, wherein, it is provided on the madial wall of annular groove upper end
It can coordinate with annular nib and be oriented to that annular nib is facilitated to be embedded into the annular guide surface in annular groove；Pass through annular guide surface
Setting, during annular nib is embedded into annular groove, annular nib can with annular guide surface coordinate be oriented to side
Just annular nib is embedded into annular groove.
After said structure, the utility model in use, works as battery short circuit or cell reverse arranging occurs
During charging phenomenon, the air pressure of inside battery is excessively high, and the fluid sealant of through hole lower end can be open-top, so that inside battery
Air is discharged by through hole, and then the phenomenon that the air pressure of inside battery can be reduced, battery is avoided to explode.
Description of the drawings
For ease of explanation, the utility model is described in detail by following specific implementations and attached drawing.
Fig. 1 is the schematic cross-sectional view of the utility model.
Specific embodiment
Specific embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
