When the staff opens the cabinet door during maintenance, the moving block deviates to one side of the telescopic rod under the drive of the connecting rod 1, and when the moving block pushes the L-shaped rod to deflect, the L-shaped rod drives the resistance rod 1, and the resistance rod 1 drives the resistance rod 2 to be clamped in the fixing hole for limiting, thereby limiting the cabinet door from swinging back and forth.

[0007] Preferably, heat dissipation holes are provided on the surface of the cabinet body, so that the heat generated by the equipment in the switch cabinet during use can be dissipated through the heat dissipation holes.

[0008] Preferably, a filter is fixedly connected to the inner side of the cabinet to prevent external dust from entering the cabinet when external air and internal air are exchanged.

[0009] Preferably, a groove is provided on the cabinet door, and the cabinet door is opened through the groove.

[0010] Preferably, the door frame is provided with a side flange, which can effectively ensure the sealing of the switch cabinet and prevent external rainwater from entering.

[0011] Preferably, the pull rod passes through the second slide groove and is slidably connected to the second slide groove, so that the pull rod drives the concave sliding block to slide on the door frame.

[0012] Compared with the prior art, the utility model provides a switch cabinet with a door frame structure, which has the following beneficial effects:

[0013] 1. When the switch cabinet with a door frame structure is in use, when the staff is repairing the equipment and opens the cabinet door, the connecting rod 1 drives the L-shaped rod, and the L-shaped rod drives the second resistance rod to be clamped into the fixing hole, so that the cabinet door is fixed to prevent the cabinet door from swinging back and forth when the staff is repairing.

[0014] 2. The switch cabinet with a door frame structure usually generates a large amount of heat when in use. A filter is provided inside the cabinet and heat dissipation holes are provided outside the cabinet so that the external air can be quickly exchanged with the air inside the cabinet. When the external air enters the cabinet, it will be filtered through the filter, thereby keeping the cabinet equipment clean. BRIEF DESCRIPTION OF THE DRAWINGS
