Both the iron piece 534 and the operating rod 526 can be inserted into the slot 532 on the adjacent blocking plate 507.

[0069] The implementation principle of a single-phase electric energy meter box in the embodiment of the present application is as follows: first, the active magnet 517 is driven to move horizontally, and the active magnet 517 drives the unlocking magnet 516 and the unlocking block 515 to move through the magnetic force, so that the unlocking block 515 releases the lock of the operating hook 524 and the meter box door 400, and then drives the blocking plate 507 to rise, and the blocking plate 507 drives the driving rack 519 to rise, and the driving rack 519 drives the gear 520 to rotate, and the gear 520 then drives the linkage rack 521, the locking rod 511 and the operating hook 524 to descend, so that the locking rod 511 is no longer inserted into the meter box door 400, and finally the locking rod 511 and the operating hook 524 are inserted into the operating groove 522 on the blocking plate 507, and the operating hook 524 is hooked and cooperated with the operating bar 523 to lock the blocking plate 507 to prevent the blocking plate 507 from descending, so that the mounting hole 502 is opened, and the staff can operate the outgoing line switch 215.

[0070] On the contrary, the slider 528 is first moved horizontally to release the lock of the operating hook 524 and the operating bar 523, and then the blocking plate 507 is driven to descend. The blocking plate 507 drives the driving rack 519 to descend, and the driving rack 519 drives the gear 520 to rotate. The gear 520 then drives the linkage rack 521, the locking rod 511 and the operating hook 524 to rise. The locking rod 511 and the operating hook 524 pass through the first hole 513, the punching hole 219 and the second hole 415 in sequence, and finally the operating hook 524 is hooked and matched with the meter box door 400, further locking the meter box door 400, so that the electricity thief cannot open the meter box door 400 after unlocking the lock of the meter box door 400, thereby preventing the electricity from being stolen by the electricity thief.

[0071] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present application should be included in the scope of protection of the present application.
