Description
Technical field the utility model alkaline battery lid belongs to field of batteries, particularly relates to a kind of structure of battery cover.
The existing battery of background technology is by battery case, battery cover and battery are formed, battery cover is the important component part of battery, it is except the effect of playing sealed cell, also play the effect of safety valve, the universal battery lid is formed mainly by battery cap, ball sealer is formed, spot-welded together with spot welding machine battery cap and battery capping shell, and make the certain space of formation between battery cap and the battery capping, and ball sealer is placed in the space that forms between battery cap and the battery capping, and ball sealer has certain elastic compression rate, ball sealer is blocked the gas outlet of battery capping, when battery when discharging and recharging, air pressure inside is too high, requires ball sealer to be out of shape rapidly and gets rid of the gas that inside battery produces, the assurance battery is not blasted, and improves the fail safe of battery.Battery is in the charging later stage, and anodal one-tenth current charge efficient reduces, and side reaction generation oxygen takes place thereupon, and the oxygen of generation is realized the oxygen recombination reaction in negative terminal surface, and the speed of this reaction is relevant with oxygen pressure, so battery cover will have certain voltage endurance capability.Therefore battery cover has suitable stable open and close valve pressure, is vital to battery performance.When the pressure in the gas outlet of battery capping is increased to safety margins, the ball sealer distortion, the space of internal gas between battery cap and battery capping is discharged to the atmosphere, when air inlet pressure during less than set point, stop exhaust, also there are some shortcomings in this junction structure, because it is bigger that ball sealer is opened pressure differential, be about about 20%, require the precision of welding and ball sealer very high, processing cost rises.The ball sealer open degree is very limited, and air displacement is also very little, causes exhaust untimely easily, and causes that opening pressure departs from set point far away after repeatedly opening, and the easy like this exhaust pressure that causes reduces or raises, and influences battery performance or causes explosion hazard.
The purpose of this utility model is to avoid weak point of the prior art and provides a kind of manufacturing simple, and assembling is easy, and production cost is low, can adjust switching pressure more accurately, prevents the explosion-proof alkaline battery lid of the situation generation that air flue is shut simultaneously.
The content the purpose of this utility model of utility model reaches by following measure, it is by the battery capping, battery cover and sealing ring are formed, the battery capping is mounted on the battery container, battery cover is a T snap riveting nail, there is a cavity gas off-take in portion at T snap riveting ailing, on cavity gas off-take wall, venthole is arranged, on the battery capping, the gas outlet is arranged, battery cover is arranged in the gas outlet, be provided with sealing ring between the T type end side of T snap riveting nail and battery capping, the nail end surface is bent in battery capping invagination, with battery cover fixedly riveting on the battery capping, when the gas pressure that produces in the battery is increased to safety margins, gas enters into gas outlet on the battery capping by the cavity gas off-take in the nail portion of battery cover from the venthole on the gas off-take wall, and the gas crush seal circle distortion in the battery realizes that battery emits gas.Sealing ring can be adjusted switching pressure more accurately, prevents that simultaneously the situation that air flue is shut from taking place.Battery cover is the method with machinery, and the mode by rivet is riveted on the battery capping, and the processing aspect is easy.
In order to reduce procedure, battery cover of the present utility model is a T snap riveting nail, on the battery capping, the gas outlet is arranged, battery cover is arranged in the gas outlet, the nail portion diameter of T snap riveting nail is less than the diameter of battery capping gas outlet, between battery capping and nail portion, form the space, between the T type end side of T snap riveting nail and battery capping, be provided with sealing ring, the nail end surface is curved in battery capping invagination, battery cover is fixed on the battery capping, and when the gas pressure that produces in the battery was increased to safety margins, gas was by forming the space between battery capping and nail portion, the distortion of crush seal circle, the realization battery is emitted gas.
The employed rivet of the utility model is the nickel plating part, and its shape can have various ways.It also can be other metalwork.
Sealing ring of the present utility model can be that various rubber are made.
The utility model manufacturing is simple, cost is low, precision is high, air displacement is big, suitable property is strong, it regulates outlet passageway by the contraction of rubber seal, can adjust switching pressure more accurately, prevent that the situation that air flue is shut from taking place, safe and reliable, realizing explosion-proof, is a kind of safety anti-explosive alkaline battery lid.
