Battery.
In order to realize above-mentioned technical purpose, the technical solution that the utility model explosion-proof lithium battery uses for：
A kind of explosion-proof lithium battery is held in the palm including housing, set on the upper cover of surface of shell and set on the side of upper cover two bottom sides,
The upper lid surface both ends are respectively equipped with the first through hole passed through for positive terminal and the second through-hole passed through for negative terminal, the side
Support is equipped with sliding slot in the horizontal direction, and the capping that middle part carries the first leather bag is equipped on the outside of the sliding slot, and inside is inserted with adjusting knot
Structure, the adjustment structure include being right against the second leather bag of upper cover bottom, and the second leather bag both sides are equipped with top and carry bore spine
Curved rod, the curved rod is inserted in sliding slot and the curved rod forepart asks forepart inconsistent with the side, the bore spine
Tip is right against the first leather bag, and the circular saw for being placed in upper cover bottom is equipped with above second leather bag.
Preferably, the first gasket is equipped at the first through hole, second through hole is equipped with the second gasket.Pass through
First gasket and the second gasket are set, are improved overall sealing performance.
Preferably, the curved rod surface is equipped with the looping pit passed through for positive terminal.By setting looping pit, make curved rod
In moving process ensure positive terminal stabilization across.
Preferably, the curved rod surface is equipped with the looping pit passed through for negative terminal.By setting looping pit, make curved rod
In moving process ensure negative terminal stabilization across.
Preferably, the curved rod bottom is equipped with the limiting catch for limiting.Catch is limited by setting, avoids arc
Bar is pierced by sliding slot.
Preferably, the limiting catch height is more than the sliding slot internal diameter.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is used cooperatively using the second leather bag and circular saw, the gas that lithium battery is made to generate when overcharging
It is tentatively discharged, lithium battery is avoided to explode；The gas push curved rod movement gradually increased in lithium battery, and then poke
First leather bag and discharge gas, the security performance of lithium battery is made to be further improved, is prolonged the service life；By adjusting
Body structure surface sets upper cover, is intercepted the film flying that other component generates due to gas expansion occurs to explode in lithium battery, enabled
The stability of structure is improved.
