[0031] like Figure 1 and Figures 3-7 As shown, a power distribution cabinet with an anti-misoperation interlocking mechanism includes a power distribution box 1, a sliding baffle 3, and a U-shaped locking rod 4. A door 2 is rotatably mounted on the power distribution box 1. The power distribution box 1 includes a rotating sleeve 101 and a wiring hole 102. The power distribution box 1 is a cavity with an open front. Multiple rotating sleeves 101 are fixedly installed on one side of the opening of the power distribution box 1. A rotating mounting rod 202, corresponding to each rotating sleeve 101, is provided on one side of the door 2. The door 2 is rotatably mounted on the rotating sleeves 101 via the rotating mounting rod 202. A wiring hole 102 is provided at the upper end of the power distribution box 1. The busbar extends through the wiring hole 102 into the power distribution box 1 and connects to the switch 5. The door 2 has a knife switch opening 201. A sliding baffle 3 is slidably installed on the door 2 and can slide to cover the knife switch opening 201. The door 2 has sliding grooves 203 on both sides of the knife switch opening 201, and the sliding baffle 3 is vertically slidably installed in the sliding grooves 203. The sliding baffle 3 has a square plate structure and is made of insulating material. The sliding baffle 3 includes a handle 303 and a stop bar 204. The handle 303 is fixedly installed on the front of the sliding baffle 3, and the stop bar 204 is installed on the back of the sliding baffle 3. By covering the knife switch opening 201 with the sliding baffle 3, when the circuit breaker 5 is closed, the sliding baffle 3 can slide upward and be locked together with the circuit breaker 5 by the U-shaped locking rod 4, so that the door 2 cannot be opened without the U-shaped locking rod 4 being opened. A hook 503 is provided on the knife switch handle 501 near the stop bar 204, and the hook 503 abuts against the stop bar 204. When the switch handle 501 is not pulled, the stop bar 204 on the box door 2 will be blocked by the hook 503 when the box door is opened, making it impossible to open the box door 2. Therefore, the staff can only open the box door 2 by turning off the power switch 5 first.

[0032] like Figure 1 , Figure 2 and Figure 7As shown, a circuit breaker 5 is installed inside the distribution box 1. The circuit breaker 5 includes a knife handle 501 for energizing or de-energizing. The knife handle 501 is movably disposed in the knife handle movable opening 201. A U-shaped locking rod 4 is used to lock the energized knife handle 501 and the sliding baffle 3 together. The sliding baffle 3 is provided with a sliding mounting base 301 and a mechanical lock body 302. The U-shaped locking rod 4 passes through the sliding mounting base 301 and the knife handle 501 and is locked in the mechanical lock body 302. The sliding mounting base 301 includes a sliding hole 304. The sliding mounting base 301 is provided with a matching sliding hole 304 corresponding to the position of the U-shaped locking rod 4. The U-shaped locking rod 4 slides through the sliding hole 304. A through hole 502 is provided transversely through the knife handle 501. The U-shaped locking rod 4 slides through the through hole 502. The mechanical lock body 302 contains a lock cylinder, which is composed of precision-cast blades. Each blade has a code that corresponds to the tooth shape on the key. The lock cylinder has small steel cores on both sides. When locking, the precision-cast blades are uneven. After inserting the key and turning it, the blades are aligned and a uniform groove appears. The small steel cores slide into the groove, allowing the outer lock cylinder shell to rotate. Simultaneously, the lock body also has small steel balls to hold the U-shaped lock beam in place when locking and to allow it to move when unlocking. To open the door 2, the mechanical lock body 302 needs to be opened, and then the U-shaped lock rod 4 needs to be pulled out from the knife handle 501 until it does not affect the opening and closing of the knife handle 501, without leaving the sliding mounting base 301. Then, the sliding baffle 3 can be slid down to expose the knife handle's movable opening 201, allowing the knife handle 501 to be pulled down and opened, thus cutting off the power. After the knife handle 501 is pulled down, the hook 503 will not obstruct the stop bar 204, making it easy to open the door 2 for internal maintenance.
