DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Please refer to Figures 1 to 3 As shown in Figures 1 to 3 , an embodiment provided by the present utility model is a frequency conversion cabinet convenient for maintenance, including a frequency conversion cabinet 1. An anti-collision groove 6 is provided on one side of the frequency conversion cabinet 1. An inspection door 2 is rotatably installed inside the anti-collision groove 6. A hinge member 15 is rotatably installed at the position where the inspection door 2 is connected to the inner wall of the frequency conversion cabinet 1. A plurality of limit grooves 14 are provided on one side surface of the inspection door 2. A plurality of limit insertion rods 9 are slidably installed inside the anti-collision groove 6. One ends of the limit insertion rods 9 are slidably inserted into the limit grooves 14 respectively.

[0019] A sliding groove 7 is provided on the inner side surface of the anti-collision groove 6. The other ends of the limit insertion rods 9 are slidably clamped into the sliding groove 7 respectively. Three adjustment grooves 8 are provided on the inner wall surface of the frequency conversion cabinet 1 near the sliding groove 7. One ends of the plurality of limit insertion rods 9 are fixedly connected with three adjustment rods 10 respectively. The three adjustment rods 10 are slidably clamped into the adjustment grooves 8 respectively. Oblique grooves are provided on the side surfaces of the limit insertion rods 9 close to the frequency conversion cabinet 1.

[0020] Through the cooperation of the inspection door 2 and the hinge member 15, when the device is in use and it is necessary to repair the components inside the frequency conversion cabinet 1, the staff can input a password at the console 3 to drive the electric push rod 11 to pull back its output end, thereby pulling the adjustment rod 10 and the limit insertion rod 9 to move towards the electric push rod 11, and then releasing the limit of the limit insertion rod 9 on the inspection door 2. At this time, the inspection door 2 can be rotated inward to be opened, enabling the staff to conveniently enter the frequency conversion cabinet 1 for maintenance while avoiding the situation that the inspection door 2 is accidentally opened by non-staff.

[0021] Electric push rods 11 are fixedly installed on the inner wall surfaces of the inspection door 2 near the adjustment grooves 8 respectively. The output ends of the electric push rods 11 are fixedly connected with connecting sleeves 12 respectively. The adjustment rods 10 are movably inserted into the connecting sleeves 12 respectively.

[0022] A plurality of magnetic attraction blocks 13 are provided on the inner wall surface of the frequency conversion cabinet 1 near the hinge member 15. Two heat dissipation openings 4 are provided on the outer surface of the frequency conversion cabinet 1.

[0023] Through the arrangement of the magnetic attraction blocks 13, after the inspection door 2 is opened towards the inside of the frequency conversion cabinet 1, it will be adsorbed on the inner wall of the frequency conversion cabinet 1 by the magnetic attraction blocks 13, avoiding the situation that the inspection door 2 automatically closes due to wind force or other reasons and traps the staff inside the frequency conversion cabinet 1. At the same time, through the cooperation of the adjustment rod 10 and the adjustment groove 8, when the staff is performing maintenance inside the frequency conversion cabinet 1, if the inspection door 2 automatically closes for some unknown reason, the staff can push the adjustment rod 10 inside the adjustment groove 8 to move the limit insertion rod 9 out of the limit groove 14, releasing the limit of the limit insertion rod 9 on the inspection door 2, enabling the staff to open the inspection door 2 inside the frequency conversion cabinet 1 and avoiding the situation that the staff is trapped.

[0024] A control console 3 is provided at the position between the heat dissipation port 4 and the maintenance door 2. The control console 3 is electrically connected to the electric push rod 11. Door handles 5 are provided on both side surfaces of the maintenance door 2.

[0025] When this frequency conversion cabinet convenient for maintenance is in use, through the cooperation of the maintenance door 2 and the hinge 15, when the device is in use and it is necessary to maintain the components inside the frequency conversion cabinet 1, the staff can input a password at the position of the control console 3 to drive the electric push rod 11 to pull back the output end, thereby pulling the adjusting rod 10 and the limit insertion rod 9 to move towards the direction of the electric push rod 11, and then releasing the limit of the limit insertion rod 9 on the maintenance door 2. At this time, the maintenance door 2 can be rotated inward to open the maintenance door 2, enabling the staff to conveniently enter the inside of the frequency conversion cabinet 1 for maintenance.

[0026] Through the setting of the magnetic attraction block 13, after the maintenance door 2 is opened towards the inside of the frequency conversion cabinet 1, it will be adsorbed on the inner wall of the frequency conversion cabinet 1 through the magnetic attraction block 13, avoiding the situation that the maintenance door 2 automatically closes due to reasons such as wind force and traps the staff inside the frequency conversion cabinet 1. At the same time, through the cooperation of the adjusting rod 10 and the adjusting groove 8, when the staff is performing maintenance inside the frequency conversion cabinet 1, if the maintenance door 2 automatically closes for some unknown reason, the staff can move the limit insertion rod 9 out of the limit groove 14 by pushing the adjusting rod 10 inside the adjusting groove 8, releasing the limit of the limit insertion rod 9 on the maintenance door 2, enabling the staff to open the maintenance door 2 inside the frequency conversion cabinet 1 and avoiding the situation of the staff being trapped.

[0027] When the maintenance door 2 is closed, the surface of the maintenance door 2 will hit the inclined groove on the surface of the limit insertion rod 9, causing the limit insertion rod 9 to retract into the inside of the electric push rod 11. Then, after the maintenance door 2 is completely closed, the limit insertion rod 9 will be driven by the electric push rod 11 to push towards the direction of the limit groove 14 to limit the maintenance door 2, avoiding the situation that the maintenance door 2 is accidentally opened by non-staff.
