However, because the carbon rod and the middle hole of the sealing ring are in interference fit, when the carbon rod is inserted into the middle hole of the sealing ring, the plastic around the middle hole can deform firstly, if the acting force between the carbon rod and the middle hole is too large and the deformation is too serious, at the moment, because the plastic surrounding the carbon rod at the middle hole position is higher than the plastic plane by no more than 1.5mm, the middle hole is not strong enough or even can be cracked, the sealing quality problem is caused, and the quality problems of battery crystallization or electrolyte leakage and the like are caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's the aforesaid is not enough, thereby provide one kind and can eliminate when the carbon stick inserts, the excessive deformation of mesopore plastics or break and produce the explosion-proof zinc-manganese cell to the influence of battery sealing performance.
In order to solve the technical problems, the invention adopts the technical scheme that: an explosion-proof zinc-manganese battery comprises a zinc cylinder punched into a tank body, a battery cell of a battery anode arranged in the zinc cylinder, and a repressing ring arranged above the battery cell; the carbon-point of setting at a zinc section of thick bamboo center, the cover has the sealing washer on the carbon-point, and the carbon-point upper end is stamped positive polar cap, its characterized in that: the sealing ring comprises an outer edge part attached to the inner wall of the zinc cylinder and a central column provided with a central hole for accommodating the carbon rod, and the central column and the outer edge part are in transitional connection through a web plate (namely a connecting plate for connecting the central column and the outer edge part) to form a groove with the upper surface and the lower surface of the sealing ring sunken inwards; the upper end surface of the middle column is higher than or flush with the upper end surface of the outer edge part, and a 1/3 annular gap is formed in the circumferential direction of the middle column; the positive electrode cap is positioned at the periphery of the carbon rod and is positioned right above the center column of the sealing ring.
By adopting the structure, the upper end face of the central column is higher than or flush with the upper end face of the outer edge part, so the strength of the central column is enhanced, meanwhile, the positive electrode cap is positioned at the periphery of the carbon rod and is positioned right above the central column of the sealing ring, when the battery is assembled, the carbon rod is inserted into the explosion-proof sealing ring, and even if plastic around the central hole is deformed, the plastic can be also propped by the positive electrode cap above, so that excessive deformation or breakage of the plastic is prevented. Meanwhile, when the internal pressure of the battery is too high and the temperature rises, the 1/3 annular notch is thin and low in strength, so that the battery is easier to deform, and can deform to release gas in advance, and the battery is effectively prevented from explosion.
Preferably, the side wall of the positive electrode cap is provided with 2 symmetrical air holes, and by adopting the structure, when the internal pressure of the battery is too large, the temperature is increased and gas is generated, the gas can enter the positive electrode cap through the 1/3 annular gap and is released to the outside through the air holes in time, so that the explosion of the battery is further effectively prevented.
