The threaded rod 106h is further moved, and the threaded rod 106h drives the sliding block 106a to move to one side along the limiting groove. The sliding block 106a drives the internal reset spring 106d and the block 106e to move. The block 106e drives the second limiting blocks 106f set on both sides to move. When the door moves to a suitable position, the threaded rod 106h is rotated, and the threaded rod 106h moves in a direction close to the sliding block 106a. The threaded rod 106h cooperates with the The cabinet 101a has a fixing effect on the sliding block 106a. The key is further inserted into the unlocking component 105 to release the locking component 104 from locking the movable door 101b, and the movable door 101b is further opened. After the movable door 101b is opened, the block 106e moves downward along the mounting hole 106b under the action of the return spring 106d.

[0043] Preferably, the key is inserted into the limit hole 105c opened inside the rotating shaft 105b, and the first limit block 105e is pushed upward. The first limit block 105e moves upward to squeeze the elastic rubber block 105f. After being squeezed, the elastic rubber block 105f undergoes elastic deformation, causing the first limit block 105e to fall off the limit hole 105c, and the rotating shaft 105b is further rotated. After the rotating shaft 105b rotates, the second magnet 105d is separated from the iron block 104c, and the iron block 104c is reset to the inside of the second mounting groove 104a under the action of the first magnet 104b. The rotating shaft 105b is reset under the action of the torsion spring 105g. When the movable door 101b is closed, the second magnet 105d adsorbs the iron block 104c to the outside of the rotating shaft 105b.

[0044] It should be noted that the magnetic force of the second magnet 105d is greater than the magnetic force of the first magnet 104b.

[0045] Furthermore, a through hole is opened on one side of the installation bin 105a, and the through hole passes through one side of the installation bin 105a, and the through hole is adapted to the rotating shaft 105b.

[0047] Furthermore, a curved surface is provided at the bottom of the block 106e.

[0048] Furthermore, a mounting hole is opened inside the cabinet 101a, and the rotating disk 102b is installed inside the mounting hole, and the diameter of the mounting hole is larger than the diameter of the rotating disk 102b.

[0049] When in use, before opening the door, the threaded rod 106h can be rotated first to move the threaded rod 106h in a direction away from the sliding block 106a. The threaded rod 106h is further moved, and the threaded rod 106h drives the sliding block 106a to move to one side along the limiting groove. The sliding block 106a drives the internal reset spring 106d and the block 106e to move. The block 106e drives the second limiting blocks 106f set on both sides to move. When it moves to a suitable position, the threaded rod 106h is rotated, and the threaded rod 106h moves in a direction close to the sliding block 106a. The threaded rod 106h cooperates with The cabinet 101a has a fixing effect on the sliding block 106a. The key is further inserted into the unlocking component 105 to release the locking component 104 from locking the movable door 101b, and the movable door 101b is further opened. After the movable door 101b is opened, the block 106e moves downward along the mounting hole 106b under the action of the return spring 106d. During the downward movement of the block 106e, the second limit block 106f is driven to move downward along the limit groove 106c. The block 106e is stuck on one side of the movable door 101b, and the opening angle of the movable door 101b is fixed after the door is opened.

[0050] When the movable door 101b is opened, the rotating rod 102a is driven to rotate, and the rotating rod 102a drives the rotating disk 102b to rotate, and the rotating disk 102b pulls the volute spring 103c to rotate. At the same time, the rotating rod 102a drives the rotating shaft 103b to rotate through the synchronous belt 102c, and the rotating shaft 103b drives the volute spring 103c to rotate, so that the volute spring 103c is tightened, and the block 106e fixes the angle of the movable door 101b after it is opened.

[0051] Insert the key into the limiting hole 105c opened in the rotating shaft 105b, push the first limiting block 105e upward, and the first limiting block 105e moves upward to squeeze the elastic rubber block 105f. After being squeezed, the elastic rubber block 105f undergoes elastic deformation, so that the first limiting block 105e is separated from the limiting hole 105c, and the rotating shaft 105b is further rotated. After the rotating shaft 105b rotates, the second magnet 105d is separated from the iron block 104c, and the iron block 104c is reset to the inside of the second mounting groove 104a under the action of the first magnet 104b. The rotating shaft 105b is reset under the action of the torsion spring 105g. When the movable door 101b is closed, the second magnet 105d adsorbs the iron block 104c to the outside of the rotating shaft 105b.

[0052] In summary, the present invention sets a cabinet unit, and the cabinet assembly can drive the transmission assembly to rotate, and the transmission assembly drives the door closing assembly to rotate, and at the same time the limit assembly has a limiting effect on the open cabinet door, which makes it convenient for maintenance personnel to inspect the inside of the distribution cabinet. After the maintenance is completed, the maintenance personnel only need to push the cabinet door to release the limit of the cabinet door by the limit assembly, and under the action of the door closing assembly, the door closing assembly drives the transmission assembly to rotate, and the transmission assembly drives the cabinet door to rotate to achieve the door closing effect. At the same time, after the cabinet door is closed, the cabinet door is locked under the action of the locking assembly, which can prevent the cabinet door from being opened for a long time, and small animals from entering the distribution cabinet to cause damage to the interior of the distribution cabinet, thereby ensuring the normal operation of the distribution cabinet.
