Title:
LEAD-ACID BATTERY ELECTRIC EYE
Document Type and Number:
WIPO Patent Application WO/2020/177090
Kind Code:
A1
Abstract:
Provided in the present utility model is a lead-acid battery electric eye, comprising an electric eye body and a sealing ring, the electric eye body comprising a light column and a column cap, an outer thread section being provided on the light column, a sealing groove being provided between the outer thread section and the column cap, a wedge-shaped groove being arranged on the column cap, the side of the wedge-shaped groove facing the fastening direction of the outer thread section having an upright face perpendicular to the column cap and the side of the wedge-shaped groove facing the loosening direction of the outer thread section having an inclined face inclined relative to the column cap, and the sealing ring being sleeved in the sealing groove. By means of arranging the wedge-shaped groove on the column cap, the electric eye body can be driven to be tightened on the storage battery case by pushing the upright surface with a special tool, and the assembly does not easily damage the electric eye; however, due to the presence of the inclined surface, it is difficult to unfasten the electric eye from the storage battery case, thereby preventing gas leakage or acid leakage, so that the service life of the storage battery is relatively long.
