Column is connected by conductor；The explosion-protection equipment has movable plate, the first piston part being fixed below movable plate, is fixed on movable plate
Second piston part of lower section, third lid lower surface are fixed with guide rod, and the movable plate has the through-hole passed through by the guide rod,
There is compressed spring, first lid to have first sealed by first piston part between the movable plate and the third lid
There is the second explosionproof hole sealed by second piston part, the third lid to have venthole for explosionproof hole, second lid.
Further, the quantity of the guide rod, the through-hole and the compressed spring is two.
Further, each guide rod is that there are one the compressed springs for set.
Further, between first positive terminal and the first lid, between the first positive terminal and third lid, the first negative terminal
And first between lid, between the second positive terminal and the second lid, between the second negative terminal and the second lid, the second negative terminal and third lid
Between all have rubber seal.
Further, the movable plate is plastic plate.
Further, the venthole has 2.
Advantageous effect：The power battery of the present invention, the explosion-proof plug synchronous falling of the first and second lid, when the explosion-proof plug of side goes out
When now loosening, since other side explosion-proof plug fastens, the position of movable plate is fixed, and non-air pressure reason can be avoided to cause
Explosion-proof plug loosen.
