[0053] Optionally, in this embodiment, four protrusions 140 are provided on the side of the first positioning plate 100 facing the door panel 20, and the four protrusions 140 all pass through the spray coating of the door panel 20 and are electrically connected to the metal of the door panel 20. Such a design provides more grounding points, enhances the grounding effect, and improves the safety and stability of the system.

[0054] Optionally, the door panel correction device further includes a knob lock 400, which includes a lock body 410, a locking member 420 and a lock tongue 430. The locking member 420 is used to fix the lock body 410 on the door panel 20, and the lock tongue 430 is rotatably connected to the lock body 410. After the cabinet door is closed, the lock tongue 430 is rotated so that the lock tongue 430 is in contact with the side of the second positioning plate 200 away from the pulley assembly 210, thereby limiting the lock tongue 430 from moving in the opening direction of the door panel 20, thereby limiting the door 20 from being opened. By providing the knob lock 400, the door panel 20 is locked to the cabinet body 10 through the knob lock 400 after the door panel 20 is corrected in place. Such a design can ensure that the door panel 20 remains in a stable position after closing, prevents accidental opening or movement, and enhances the safety and stability of the switch cabinet. The use of the knob lock 400 also makes it more convenient to open and close the door panel 20. The user can easily lock or unlock the door panel 20 through the knob, thereby improving the operability and ease of use of the switch cabinet.

[0055] Optionally, the locking piece 420 is a locking nut, and one end of the lock body is provided with an external thread.

[0056] Optionally, the second through hole 150 is a rectangular hole, and a rectangular boss is provided on the lock body. The rectangular hole is sleeved on the rectangular boss, which can prevent the first positioning plate 100 from being skewed before the locking nut is tightened, thereby ensuring the accuracy of the position of the first positioning plate 100 and improving the reliability of the door panel correction device.

[0057] Optionally, the door panel 20 is provided with a first through hole, the first positioning plate 100 is provided with a second through hole 150, the second through hole 150 is opposite to the first through hole, and one end of the lock body 410 passes through the first through hole and the second through hole 150 in sequence and is threadedly connected to the locking member 420. The first positioning plate 100 is fixed to the door panel 20 by the knob lock 400, which simplifies the assembly process and makes the installation process more efficient and convenient. In addition, the first through hole on the door panel 20 corresponds to the second through hole 150 on the first positioning plate 100, which ensures that the first mounting plate is accurately installed on the door panel 20.

[0058] The correction process of the door panel correction device provided in this embodiment is as follows:

[0059] When the door panel 20 is closed, the door panel 20 moves closer to the frame 11 of the cabinet 10. When the first positioning plate 100 contacts the second positioning plate 200, the trumpet-shaped opening surrounded by the two bent portions 130 on the first positioning plate 100 guides the pulley assembly 210 to enter the accommodating space 110. After the pulley assembly 210 enters the accommodating space 110, each pulley 212 is correspondingly connected to a straight plate portion 120 for rolling, thereby guiding the door panel 20 to move along a predetermined route and correcting the closed position of the door panel 20; when the pulley 212 rolls along the straight plate portion 120 to the bottom of the groove of the accommodating space 110, the pulley assemblies 210 on the first positioning plate 100 and the second positioning plate 200 are in place, the door panel 20 stops moving, and the lock tongue 430 of the rotary lock is rotated and clamped on the frame 11 of the cabinet 10 to lock and fix the door panel 20.

[0060] This embodiment also provides a switch cabinet, such as Figure 6 As shown, the switch cabinet includes a cabinet body 10, a door panel 20 and the door panel correction device as mentioned above.
