[0036] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1 As shown, a low-voltage power distribution cabinet with a novel door lock rod locking mechanism comprises a cabinet body 1 and a door lock rod locking mechanism.

[0038] The front end of the cabinet 1 has two front doors 2 , which are adapted to each other and play a role in opening or closing the cabinet 1 .

[0039] The door lock rod locking mechanism comprises a door lock seat 3, two door lock rods and two locking brackets 4. Figure 2 As shown, the door lock seat 3 is arranged in the middle position of the inner wall of any one of the front doors and is located on a side close to the other front door.

[0040] The two door lock rods are vertically slidably arranged on the door lock seat 3, and the two door lock rods are respectively located above and below the door lock seat 3; a driving member is provided in the door lock seat 3 for driving the two door lock rods to move closer to or away from each other in the vertical direction. The tops of the two door lock rods are provided with an inclined surface structure 5.
