At the same time, if the indoor fire is caused by a circuit fire, if the circuit is not disconnected in time, the fire will become more serious. For this reason, a smart meter with a smoke alarm mechanism is designed. Utility Model Content

Each cylindrical protrusion is slidably connected to one side of the lifting rod 16. When the arc plate 17 descends, the wire in contact with the conductive metal sheet 13 will be pushed away, so that the meter body 1 is completely powered off, so that the indoor circuit is not energized.

[0022] In this embodiment, an inverted concave plate 20 is fixedly connected to the rear end of the inner side of the mounting groove 2, and the same limiting rod 21 is fixedly connected to the top and bottom of the inner sides of the inverted concave plate 20 at both ends, and the same lifting plate 22 is slidably connected on the circumferential surfaces of the two limiting rods 21.

[0027] Working principle: A smart meter with a smoke alarm mechanism. When in use, after the meter body 1 is installed, the two incoming wires and the two outgoing wires are fixed between the first arc groove 4 and the corresponding second arc groove 12 by fixing bolts 5.

When smoke appears, the smoke alarm 8 is triggered and starts to alarm, and at the same time sends a signal to the controller 7. The controller 7 controls the micro motor 9 so that the micro motor 9 drives the screw rod 23 to rotate, so that the lifting plate 22 carries the U-shaped frame 26 descends, and the second cross bar 11 moves to the rear end through the setting of the second inclined hole 25, so that the incoming wires and the outgoing wires are loosened. At the same time, the second cross bar 11 moves synchronously with the lifting rod 16 and the arc plate 17.

When the circuit of the electric meter body 1 is connected, the storage battery 6 is charged, so that after the circuit of the electric meter body 1 is disconnected, the storage battery 6 can power the micro motor 9, the controller 7 and the smoke alarm 8, ensuring that each component can work normally for a period of time.
