Fig. 2 is an exploded schematic diagram of a partial structure of the smart metering lock device of the present invention.

Detailed ways

Please refer to FIG. 1 and FIG. 2 at the same time. The smart metering lock device of the present invention includes a lock body base 1 , an unlock handle 2 , an RFID electronic tag 4 and an electromagnetic locking component 3 . The unlocking handle 2 is arranged in the lock body base 1; the RFID electronic tag 4 is embedded in the inside of the unlocking handle 2; The unlock handle 2 is locked in the lock body base 1 .

Specifically, the lock body base 1 is provided with a handle installation groove 11 and a handle locking groove 12 which are adjacently arranged. A locking through hole 121 is defined on one side of the handle locking groove 12 .

One end of the unlocking handle 2 is disposed in the handle installation groove 11 , the other end is disposed in the handle locking groove 12 , and a notch is fixedly provided with a locking through groove 211 facing the opening of the locking through hole 121 .

Furthermore, in order to strengthen the locking of the metering box by the device, as a more optimal technical solution, the lock body base 1 further includes a rotating disc body 13 and a rotating locking component 14 . The rotating disc body 13 is installed in the handle mounting groove 11, and it is provided with a hinged groove 131; one end of the unlocking handle 2 arranged in the handle mounting groove 11 is connected to the handle mounting groove 11 through a shaft column and a torsion spring. The hinge groove 131 is connected. The rotation locking part 14 is arranged at the bottom of the handle installation groove 11 and is composed of two tongue-shaped pieces in one piece. The two tongue-shaped pieces are respectively a driving piece 141 and a locking piece 142 . The driving piece 141 is connected to the rotating disk body 13 through a rotating shaft that is connected to the handle mounting groove 11, and is driven to rotate by the unlocking handle 2 to drive the locking piece 142 to rotate to realize the locking of the metering box. tight or open. And the included angle between the two tongue-shaped pieces of the rotating locking part 14 is 120°-135°.

The electromagnetic locking component 3 is installed outside the handle locking groove 12 , and its locking end is disposed in the locking through hole 121 and can extend into the locking through groove 211 . Specifically, the electromagnetic locking component 3 includes an electromagnetic coil 31 , an iron core 32 and a locking tongue 33 . The electromagnetic coil 31 is arranged outside the handle locking groove 12; one end of the iron core 32 is arranged in the electromagnetic coil 31, and the other end is exposed outside the electromagnetic coil 31; the lock tongue 33 is arranged in the locking through hole 121, And it is connected with one end of the iron core 32 exposed outside the electromagnetic coil 31 , and it can be driven by the electromagnetic coil 31 to extend into or out of the locking through slot 211 .
