Description

A vent cap with discharge display panel for a battery}

The present invention relates to a vent cap for a battery having a discharge amount confirmation port.

In particular, the present invention relates to a battery vent cap having a discharge amount confirming port capable of checking a charge / discharge state in units of cells of a battery in a battery in which an electrolyte solution of a battery is periodically or aperiodically replenished.

Typical PT batteries are mainly used in vans, jeeps, buses and commercial vehicles because of their excellent instantaneous starting capability and little seasonality.

Referring to FIG. 1, an external structure of a general PT storage battery is described. The storage battery 10 includes caps 15 and 17 respectively corresponding to interior cells on an upper surface of a body portion 11 containing a plurality of cells and electrolytes. And a discharge check sphere 19 which can confirm the discharge amount of the battery. Here, reference numeral 13 denotes a handle, and 12 and 14 denote (+) (−) electrode terminals.

The battery 10 having such a configuration is provided with the discharge check sphere 19, but actually has a disadvantage in that the discharge amount of the entire battery 10 can not be confirmed because it has a structure that can confirm the discharge amount of only a specific cell. .

Since the military vehicle requires daily inspection in connection with the check of combat posture equipment, since the battery 10 of the above-described configuration is used, the vent cap 17 of the storage battery 10 is opened and the electrolyte is checked during the daily inspection of the vehicle. In addition, the state of charge of the battery should be checked.

In addition, since the battery 10 of such a configuration checks using a tool such as wooden chopsticks when checking the state of the electrolyte, it is harmful to the human body and also includes a problem that a quick daily check cannot be performed due to military characteristics.

Here, the configuration of the vent cap 17 for replenishing the electrolyte and discharging the gas of the storage battery 10 will be described with reference to FIG. 2, and the vent cap 17 has a hollow structure having an open bottom surface and a coupling screw portion ( 17a) is formed and fastened to corresponding openings (not shown) of the storage battery 10, and an exhaust hole 17b through which gas is discharged is formed in the upper surface thereof, and a sponge member 17c is incorporated. Therefore, the evaporated gas of the electrolyte passes through the sponge member 17c of the vent cap 17 and is exhausted to the outside air through the exhaust hole 17b.

SUMMARY OF THE INVENTION An object of the present invention created to solve the above problems is to provide a vent cap for a battery having a discharge amount confirming port capable of quickly checking the charge and discharge amount in a cell unit of the battery.

An object of the present invention, the exhaust hole is formed in the upper surface, the lower surface of the hollow cover member and the open; A coupling tube having a lower end and an upper end connected to the cover member and having a coupling screw formed on an outer circumferential surface thereof; A hollow sponge member housed inside the coupling tube; A transparent discharge confirmation window is provided on at least one through hole and an upper surface, and a narrow portion having a reduced cross-sectional area is formed between upper and lower surfaces, and a discharge check hole having a hollow structure embedded in a sponge member; It is spherical shape with different colors, and is floated in correspondence with specific gravity of electrolyte solution and built between narrow section and bottom surface of discharge check port so that the battery can check "normally charged" or "over-discharged" state by the discharge confirmation window. It can be achieved by a configuration including a specific gravity check ball.

Here, the outer circumferential wall of the cover member and one side of the upper end of the coupling tube is preferably formed integrally by the connecting portion, which is integrally formed by the molding injection. The cover member is opened and closed from the coupling tube as the coupling convex portion formed on the lower inner circumferential wall of the cover member and the coupling recess formed on the upper circumferential wall of the coupling tube correspond to each other.

In addition, as the fastening screw portion formed on the lower inner circumferential wall of the cover member and the fastening screw portion formed on the upper outer circumferential wall of the coupling tube are respectively fastened or released, the cover member can be opened and closed from the coupling tube, which is coupled to the cover member. It is a configuration in which the tubular body is separated.

The specific gravity check ball is made of platinum (Pt), and the color corresponding to the "normally charged" state of the battery is green, and the color corresponding to the "over-discharged" state of the battery is red. Therefore, when the specific gravity of the electrolyte is 1.280 or more, the green specific gravity check ball is suspended, and when the specific gravity of the electrolyte is 1.280 or less, the red specific gravity check ball is suspended. In addition, when the specific gravity check ball is not suspended, the discharge confirmation window is colorless or white when the electrolyte solution is insufficient.

Here, it is preferable to process so that the diameter of specific gravity check ball may be formed larger than the inner diameter of narrow part.
