It can connect multiple electric energy meters together to realize data sharing and centralized management. It can also be used for the collection and transmission of electric energy meter data of multiple different systems. In the prior art, the electric energy meter is electrically connected to the circuit master. In order to ensure that the current can flow to the electric energy meter, the electric energy meter is provided with an input terminal and an output terminal. When the power is off, the circuit master needs to be opened to cut off the power of the entire device. In this way, the entire circuit can be powered on again only after the operation of the electric energy meter is completed. During the operation of the electric energy meter, the user cannot use electricity normally. Utility Model Content

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that users cannot use electricity normally during the operation of the electric energy meter, thereby providing an electric energy meter box with a flip mechanism that can replace the electric energy meter under power.

[0011] 1. The utility model provides an electric energy meter box with a flip mechanism for replacing an electric energy meter with power on. The electric energy meter is fixed on the flip plate. When the electric energy meter needs to be repaired, the flip plate is rotated counterclockwise to separate the second contact plate from the first contact plate, and the bottom of the second support plate will abut against the extension strip on the first support plate, thereby limiting the second support plate and the second contact plate from continuing to rotate. When the electric energy meter is repaired, the second support plate and the second contact plate need to be rotated clockwise to reset. After resetting, the back side of the second contact plate will fit with the front side of the first contact plate. This is superior to the prior art. When repairing the electric energy meter, there is no need to remove the electric energy meter. Only the flip plate needs to be rotated, the electric energy meter will be powered off, and the operator can repair the electric energy meter. When the repair is completed, the flip plate is turned back clockwise to restore the power to the electric energy meter.

[0012] 2. The utility model provides an electric energy meter box with a flip mechanism for replacing an electric energy meter with power on. The opening and closing mechanism includes an articulated rod and an articulated shaft hinged to the articulated rod. A circular hole for inserting the articulated rod is provided on the flip plate. The articulated rod passes upward from the bottom of the circular hole to supply power to the electric energy meter. When the flip plate is in the second position, the articulated rod is connected to the connecting shaft to supply power to the electric energy meter.

After the power is off, the operator can inspect the electric energy meter. After the inspection is completed, the flip plate is restored from the first state to the second state, and the electric energy meter can continue to be powered on. During the whole process, the electric energy meter can be powered on and off quickly. BRIEF DESCRIPTION OF THE DRAWINGS

After the repair of the electric energy meter 3 is completed, the second support plate 21 and the second contact plate 22 need to be rotated clockwise to reset. After resetting, the back side of the second contact plate 22 will fit with the front side of the first contact plate 12. This is better than the prior art. When repairing the electric energy meter 3, there is no need to remove the electric energy meter 3. Only the flip plate 2 needs to be rotated, the electric energy meter 3 will be powered off, and the operator can repair the electric energy meter 3.

A circular hole 6 for inserting the articulated rod 41 is provided on the flip plate 2. The articulated rod 41 passes upward from the bottom of the circular hole 6 to supply power to the electric energy meter 3. When the flip plate 2 is in the second position, the articulated rod 41 is connected to the connecting shaft to supply power to the electric energy meter 3. When the flip plate 2 switches from the second state to the first state, the articulated shaft 42 is separated from the articulated rod 41, so that the current on the articulated shaft 42 cannot be transmitted to the articulated rod 41, so that the electric energy meter 3 is powered off. After the power is off, the operator can inspect the electric energy meter 3. After the inspection is completed, the flip plate 2 is restored from the first state to the second state, and the electric energy meter 3 can continue to be powered on. During the whole process, the electric energy meter 3 can be powered on and off quickly.
