Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of battery electrolyte filling, especially relates to a battery electrolyte filling gun. BACKGROUND

[0002] Open-type batteries (such as industrial nickel-cadmium batteries) need to be regularly supplemented with distilled water to maintain the battery electrolyte within the required range to ensure that the battery has the expected charge and discharge performance. The amount of distilled water supplement needs to be strictly controlled, and too little supplement poses the risk of battery electrolyte depletion, resulting in the battery not being able to be used normally; too much supplement poses the risk of electrolyte overflow, thereby causing the surrounding components of the battery to be corroded and the environment to be polluted.

[0003] Therefore, quantitative electrolyte filling is particularly important. Most of the current devices for manual liquid supplement do not have the function of quantitative filling, and often use the method of measuring while filling, which is low in efficiency and has the defect of low precision.

In order to better limit and fix the barrel, the specific fixing mode is arranged in a structure similar to a hoop, the locking through hole is arranged on the side surface of the positioning ring, the locking bolt is installed in the locking through hole and abuts against the barrel, thereby achieving the position fixing on the barrel, and abutting against the outside of the opening of the battery, thereby achieving the limiting effect.

[0010] Further, an outer thread is arranged on the barrel, an inner thread corresponding to the outer thread is arranged in the positioning ring, and the positioning ring is fixed through cooperation of the inner thread and the outer thread. In order to better limit and fix the barrel, the specific fixing mode is arranged as a threaded installation, the outer wall of the barrel is an outer thread, and the inner hole of the positioning ring is a matching inner thread, and the barrel is fixed through the threaded installation.
