A night warning sign 12 is fixedly connected to the inner wall of the hinge plate 11. When the device is under maintenance at night, the motor 5 will start, and the output end of the motor 5 will drive the reciprocating screw 6 to move... The rotation of the reciprocating screw 6 causes the long plate 8 to rotate. However, the long plate 8 is limited by the limiting post 7.

The rise of the long plate 8 causes the connecting block 9 to rise. The movement of the connecting block 9 causes the pushing block 10 to move. After the pushing block 10 moves a certain distance, the top of the pushing block 10 will contact the hinge plate 11. Through the continued rise of the connecting block 9, the connecting block 9 will cause the pushing block 10 to squeeze and push the hinge plate 11. At this time, the hinge plate 11 will rotate at a certain angle. The rotation of the hinge plate 11 will cause the night warning sign 12 to rotate. The night warning sign 12 rotates at a certain angle. Afterwards, the night warning sign 12 will be perpendicular to the top horizontal plane of the distribution cabinet 1, allowing it to stand upright and alert surrounding people.
