Abstract

The utility model discloses an acid overflowing device for a storage battery. The acid overflowing device comprises an acid overflowing kettle, a rubber acid overflowing head and an outer cylinder, wherein the outer cylinder is arranged in an acid filling hole of a middle cover of the storage battery, the acid overflowing kettle is funnel-shaped, at least one circle of groove is arranged on a peripheral surface of a funnel nozzle which is arranged at the lower end of the acid overflowing kettle, a rubber ring is arranged in the groove in a matched manner, and the rubber acid overflowing head is axially provided with stepped through holes. When the acid overflowing device is used, a first stepped through hole is sleeved at the periphery of the funnel nozzle, and a second stepped through hole is sleeved at the periphery of the outer cylinder of the acid filling hole of the middle cover, so that excessive acid liquid can overflow into an acid kettle, acid liquid overflowed when adding acid can be prevented from polluting a storage battery shell and copper-core terminals, a shell body is prevented from being burnt due to loop current between a positive terminal and a negative terminal formed by the acid liquid on the surface of the shell body, and accelerated corrosion and the like of the copper-core terminals due to tin-plated electrolytic reaction on the surface of the copper-core terminals caused by the loop current is also avoided.

Description

A kind of storage battery sour device that overflows

Technical field

The utility model relates to a kind of storage battery, is specifically related to the excessive sour device of a kind of storage battery.

Background technology

As everyone knows, in the storage battery manufacture process, after acid solution was filled it up with, inside battery generation chemical reaction produced bubble; Acid solution can be overflowed outside the battery cover in a large number, and unnecessary acid solution can cause the pollution of battery surface and the corrosion of terminal copper core, simultaneously, and in battery charging process; Inside can produce a large amount of gas again, and big bubble appears in the valve opening place, and bubble breaks and can cause acid solution to be splashed each time, causes the pollution once more of battery container and copper core terminal; And the acid solution of surface of shell can cause anode and cathode terminals to constitute loop current; Cause the housing burn, loop current also can cause the electroplating surfaces with tin cell reaction of copper core terminal, has more increased the weight of the corrosion of copper core terminal.The macropore colloid lid that electrokinetic cell adopts mostly, the excessive sour kettle of the low capacity of existing band Rubber end can't supportingly use, and it is imperative to invent the excessive sour device of a kind of storage battery.

Summary of the invention

The technical problem that the utility model will solve provides the excessive sour device of a kind of storage battery, overcomes the defective that prior art exists.

The utility model is realized through following technical scheme:

A kind of storage battery sour device that overflows comprises that overflow acid head, battery middle cover of the sour kettle that overflows, rubber adds the outside cylinder in the sour hole, and said excessive sour kettle is funnel-form; At least have a circle groove on the spout of funnel outer peripheral face of lower end; Coupling has rubber ring in the groove, and said rubber overflows sour and is axially arranged with ladder hole, during use; First ladder hole is placed in the spout of funnel periphery, and second shoulder hole is placed in the outside cylinder periphery that middle cover adds sour hole.

The further improvement project of the utility model is, the rubber ring of first ladder hole and spout of funnel periphery is an interference fit, and the outside cylinder that second shoulder hole and middle cover add in the sour hole is an interference fit.

The utility model compared with prior art has following obvious advantage:

One, behind storage battery acidification, the second shoulder hole sleeve with the excessive acid of a rubber bottom adds acid in middle cover earlier

The outside cylinder in hole, and then rubber overflow the first shoulder hole sleeve on an acid top in the spout of funnel of the sour kettle that overflows, unnecessary acid solution can be overflow in sour kettle, can prevent to add the acid solution of overflowing after the acid and pollute battery case and copper core terminal.

Inside can produce a large amount of acid solutions again when two, charging; Unnecessary acid solution is overflow in the sour kettle that overflows; Avoid acid solution to splash and caused the secondary pollution of battery container and copper core terminal; Avoid the acid solution of surface of shell to form the anode and cathode terminals loop current and the housing of burning simultaneously, also avoided the zinc-plated cell reaction of the copper core terminal surfaces that loop current can cause, increased the weight of the corrosion of copper core terminal etc.

Embodiment

As shown in Figure 1, the utility model comprises that the overflow acid 2, battery middle cover 3 of the sour kettle 1 that overflows, rubber adds the outside cylinder 3.1 in the sour hole.Like Fig. 1,2, shown in 3, said excessive sour kettle 1 is funnel-form, has two circle grooves 1.2 on lower end spout of funnel 1.1 outer peripheral faces, and coupling has rubber ring 1.3 in the groove, and is as shown in Figure 3, and sour its funnel of kettle downward projection that overflows is rectangular, and spout of funnel is rounded.Like Fig. 4, shown in 5, rubber acid 2 downward projection that overflow are rounded, are axially arranged with ladder hole, and during use, first ladder hole 2.1 is placed in the spout of funnel periphery, with the rubber ring 1.3 of spout of funnel periphery be interference fit.Second shoulder hole 2.2 is placed in outside cylinder 3.1 peripheries that middle cover 3 adds sour hole, and is interference fit with it.

Claims
