Battery water level display device

The present invention relates to a battery water level display device, and more particularly to a battery water level display device which can be installed in a water injection hole of a battery and has a direct visual observation of the water level.

The battery installed in the general transportation vehicle (commonly known as the battery) mainly uses the chemical changes of the lead plate and the electrolyte to achieve the supply of electricity, and the electrolyte is formed by mixing water and sulfuric acid, which is easy to be generated when the battery is charged. Heat and water vapor cause water loss, so that the electrolyte water level inside the battery is gradually reduced, which is not enough to cover the lead plate, thus reducing the total discharge of the battery and shortening the service life. Therefore, adding distilled water at the right time is a necessary item for vehicle maintenance. Conducive to the addition of distilled water, generally the top surface of the battery is opened with a number of water injection holes, the water injection hole is sealed by a screw cap with a gasket, so that the electrolyte does not leak, and a water supply bottle can be provided on the top surface of the screw cap. The venting port of the vapor is used to maintain the pressure inside the battery.

For the operation of adding distilled water to the battery, it is usually to use the regular or irregular maintenance to unscrew the screw cap one by one, which causes cumbersome inconvenience and trouble, especially for large vehicles such as buses, large trucks, junction cars, etc. I feel very much.

At present, there is a screw cap with a warning function on the market. The screw cap is a transparent cover body, and an indicator rod is arranged therein. The bottom end of the indicator rod is provided with a floating body, and the indicator rod is pushed by the floating body, and is displayed by the indicator rod. The condition of the electrolyte water level, when the water level is insufficient, the indicator rod is shifted downwards. It is known that the electrolyte water level inside the battery is insufficient to carry out the work of adding distilled water.

However, since the above-mentioned indicator rod is limited by the low height of the screw cap, the length thereof is short, so that the displacement amount of the indicator rod is small, so the difference of the up and down displacement momentum is small, and if the slight difference is not noticed or negligent, the addition of distilled water is missed. It is impossible to achieve the practicality of a clearer indication.

The present invention provides a battery water level display device, which comprises a screw cover, a transparent tube, a warning rod and a sleeve; the screw cover can be screwed into the water injection hole of the battery by a sleeve, and a perforation is arranged in the center. The transparent tube is inserted into the perforation and protrudes upwardly from the upper side of the screw cap, and the top end of the transparent tube forms a venting hole communicating with the outside, and the bottom of the transparent tube is provided with a top surface facing the top surface of the screw cap. a fixed convex ring, the warning rod is disposed in the transparent tube, the top end is coated with a warning color, and the bottom end is connected with a floating piece, and the sleeve is sleeved on the inner circumferential surface of the screw cover and protrudes The bottom side of the screw cap is for accommodating the warning rod and the floating piece thereof, and the bottom end thereof is provided with a through hole communicating with the electrolyte inside the battery, and a bottom of the sleeve is disposed at a lower end of the sleeve to abut the bottom end of the screw cover. The positioning ring is defined, and at least one air guiding hole communicating with the space inside the battery is disposed immediately below the positioning ring; thereby forming a battery water level display device.

The present invention provides a battery water level display device, which uses the floating piece to float on the electrolyte and pushes the warning rod according to the sleeve movement, so that the warning rod is displaced up and down according to the transparent tube, because the transparent tube system protrudes from the The upper side of the screw cap has a long distance, so that the amount of movement of the warning rod is large, so the difference between the upper and lower displacement is large. Therefore, it is possible to clearly and visually observe whether the electrolyte water level inside the battery is sufficient, and the existing battery can be solved. Can't see the problem at a glance.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , the present invention provides a battery water level display device including a screw cover (1), a transparent tube (2), a warning rod (3) and a sleeve (4). ) composed of.

A hole (11) is provided in the center of the screw cap (1).

The top end of the transparent tube (2) is formed with a venting hole (21) communicating with the outside, and a convex ring (22) is disposed above the bottom end of the transparent tube (2).

The warning rod (3) is a tubular body, the top surface of the top end is coated with a warning color (31) containing a fluorescent component, and the bottom end is connected with a floating piece (32), the diameter of the floating piece (32) Greater than the diameter of the transparent tube (2).

The bottom end of the sleeve (4) is provided with a through hole (41) communicating with the outside, a positioning ring (42) is disposed below the top end of the sleeve (4), and at least one connection is disposed immediately below the positioning ring (42). The transparent tube (2) and the external air guiding hole (43) are provided.

When installing, please refer to Figures 1 and 3, first insert the transparent tube (2) from the bottom up into the perforation (11) of the screw cap (1), and protrude upward from the screw cap ( 1) the upper side, and the convex ring (22) of the transparent tube (2) is consolidated with the inner top surface of the screw cap (1), so that the transparent tube (2) is stably supported on the screw cap (1) On the upper side, the warning rod (3) is further accommodated in the transparent tube (2) from bottom to top, and finally the sleeve (4) receives the warning rod (3) and its floating piece (31) and is sleeved on the upper side. The inner surface of the screw cap (1) is positioned on the convex ring (22) of the transparent tube (2) and protrudes downwardly from the lower side of the screw cap (1) while utilizing the sleeve (4) The positioning ring (42) is opposite to the bottom end of the screw cap (1), thus completing the combination of the present invention.
