After the maintenance is completed, the maintenance personnel can rotate the handle 11 upwards to drive the adjusting column 10 to rotate reversely, and when the adjusting column 10 rotates reversely, the U-shaped frame 24 can be pushed by the pushing column to enable the U-shaped frame 24 to displace and the rack plate 23 to move (as shown in fig. 13-14), the rack plate 23 moves to drive the gear roller 22 on the rotating rod 12 to rotate, so that the rotating rod 12 rotates, the push rods 13 at two ends of the rotating rod 12 deflect when the rotating rod rotates, the fixing strips 14 are pushed to enable the visual inner door 9 to be separated from the outer door 7, at the moment, the rotating shaft 4 is enabled to rotate reversely by the visual inner door 9, when the visual inner door 9 is tightly attached to the cabinet body 1 convex edge 2, the cabinet body 1 can be closed, meanwhile, the circuit inside the cabinet body 1 can be connected through the first trigger rod 35 of the power-off end 5, at the moment, the alarm and the warning lamp can be sent out, when the warning lamp is warned, the visual inner door 1 can be seen through the visual window, the circuit inside the cabinet body can be reset, the maintenance personnel can be fast maintained when the cabinet door 11 is turned, the maintenance position is not fast, and the maintenance situation can be guaranteed when the maintenance is improved, and the maintenance personnel can be fast maintained, and the maintenance personnel can be fast maintain the circuit in the cabinet body through the circuit when the circuit is kept in the cabinet, and the maintenance.
Referring to fig. 13, 14 and 15, it should be noted that when the handle 11 is rotated downward, the push post of the adjusting post 10 can be separated from the two connecting rods 26 and does not drive the U-shaped frame 24 to rotate, when the handle 11 is rotated upward, the adjusting post 10 unwinds the first wire rope 32 and the second wire rope 31 and does not contact the locking of the outer door 7, and the handle 11 is initially rotated horizontally, so as to control the locking of the cabinet door and the control of the visible inner door 9 through different rotation directions of the handle 11.
Referring to fig. 12, further, a groove 39 is formed in the middle of one side of the outer door 7 away from the rotation shaft 4, a locking mechanism is arranged on one side of the cabinet door mounting cavity 3 away from the rotation shaft 4, the locking mechanism comprises a locking groove 40, a sliding block 41 is slidably arranged in the locking groove 40, a pressure spring 42 is arranged between the sliding block 41 and the locking groove 40, an inclined surface 43 is arranged on one side of the sliding block 41 away from the pressure spring 42, which is away from the convex edge 2, a through hole 44 is formed on one side of the sliding block 41, which is close to the pressure spring 42, a spiral groove 45 is formed in the inner side wall of the through hole 44, a rotary handle 46 is arranged at the position of the cabinet body 1 corresponding to the locking groove 40, a rotary rod 47 is fixedly connected to one side of the rotary rod 46, the rotary rod 47 extends through the cabinet body 1 to the inside of the through hole 44, and is fixedly connected with a deflector 48, and the deflector 48 is inserted inside the spiral groove 45.
When the cabinet door needs to be opened, the handle 11 needs to be rotated downwards simultaneously and the rotating handle 46 is rotated, the rotating handle 46 rotates to drive the rotating rod 47, and when the rotating rod 47 rotates, the sliding block 41 can be driven to move towards the inside of the locking groove 40 through the arrangement of the spiral groove 45, so that the sliding block 41 moves out of the groove 39 of the outer door 7, the first re-locking of the outer door 7 is finished, the second re-locking of the outer door 7 is released through the downward rotation of the handle 11, and the locking of the outer door 7 is finished, so that the situation that a single switch is arranged on the cabinet door is avoided, non-staff can easily open the cabinet door, and electric shock accidents are caused
Further, the upper and lower ends of the side, close to the rotary shaft 4, of the outer door 7 are provided with lantern rings, the lantern rings are sleeved on the rotary shaft 4, and the outer door 7 is matched with the cabinet door mounting cavity 3. The rotational stability of the outer door 7 is improved.
