[0002] At present, most of the domestic single-phase meter clock batteries are built in the meter. Once the battery undervoltage occurs inside the meter, if you want to replace the battery, you need to open the upper cover of the meter and cannot replace it on site. Therefore, when the battery in the meter After undervoltage, the meter can only be returned to the factory for maintenance, which is inconvenient for on-site repair of the meter. Because the cost of a single energy meter is higher than that of a battery, the replacement of the entire meter will increase the cost

The invention discloses a replaceable battery box structural assembly and a use method, which include a cylindrical box body and a box cover. The box body is provided with a negative electrode contact piece fixing block, and the box body is provided with a negative electrode contact piece outlet. The box body is provided with a negative electrode contact piece slot, and the negative electrode contact piece is clamped in the negative electrode contact piece slot, and one end of the negative electrode contact piece passes through the negative electrode contact piece outlet and contacts with the bottom surface of the negative electrode contact piece fixing block. The box body is provided with a box cover bayonet, the inner wall of the box is provided with a box cover block entrance, and the box cover is provided with a positive contact piece slot, and a positive contact piece is snapped into the positive contact piece slot , a battery is placed in the box body, and the positive pole and the negative pole of the battery are in contact with the positive pole contact card and the negative pole contact piece respectively. The replaceable battery box structural component and its use method described in the present invention can effectively solve the problem of battery undervoltage, and facilitate battery replacement without replacing the entire meter, which saves costs and facilitates on-site maintenance and repair.
Description
technical field [0001] The invention relates to the technical field of metering meters such as electric energy meters, water meters, and gas meters, and in particular to a replaceable battery box structural assembly and a use method. Background technique [0002] At present, most of the domestic single-phase meter clock batteries are built in the meter. Once the battery undervoltage occurs inside the meter, if you want to replace the battery, you need to open the upper cover of the meter and cannot replace it on site. Therefore, when the battery in the meter After undervoltage, the meter can only be returned to the factory for maintenance, which is inconvenient for on-site repair of the meter. Because the cost of a single electric energy meter is higher than that of a battery, the replacement of the entire meter will increase the cost. Contents of the invention [0003] The purpose of the present invention is to provide a replaceable battery box structural component and it...
