DETAILED DESCRIPTION

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to up, down, left, right as shown in the reference drawings; "inside and outside" refer to inside and outside relative to the outline of each component itself.

A best embodiment is given below:

As shown in Fig. 1-6, a control cabinet in this embodiment includes an electric cabinet body 1, a cabinet door 2 is rotatably connected to one side of the electric cabinet body 1, a handle 3 is provided on the outer side of the cabinet door 2, a filter 4 is fixedly provided at the inner bottom end, cooling fans 5 are provided on both sides of the electric cabinet body 1, and the cooling fans 5 are removed from the electric cabinet body 1 by a disassembly mechanism, and an observation window 24 is provided on the upper part of the cabinet door 2;

A placement plate 6 is provided inside the electric cabinet body 1 . The placement plate 6 is adjusted up and down inside the electric cabinet body 1 through an adjustment mechanism. A moisture-proof sticker is also laid on the top of the placement plate 6 .

An observation window 24 is provided on the cabinet door 2 for observing the situation inside the electric cabinet body 1 ; moisture-proof stickers are laid on the tops of the two placement plates 6 for protecting the instruments inside the electric cabinet body 1 .

Among them, the adjustment mechanism includes a rotating roller 7, a hand wheel 8, a first bevel gear 9, a second bevel gear 10 and a bidirectional threaded rod 11. The bottom end of the electric cabinet body 1 is rotatably connected to the rotating roller 7. One end of the rotating roller 7 passes through the outer wall of the electric cabinet body 1 and is fixed with the hand wheel 8. The first bevel gear 9 is installed on the rotating roller 7. The top of the first bevel gear 9 is meshed with the second bevel gear 10. The top of the second bevel gear 10 is fixed with a bidirectional threaded rod 11. The bidirectional threaded rod 11 passes through the placement plate 6 and is rotatably connected to the electric cabinet body 1. The rotating roller 7 is also provided with a limiting component.

There are two placement plates 6 in this embodiment but the number is not limited to two. According to the length of the placement plates 6, the number and position of the bidirectional threaded rods 11 are set according to the placement plates 6 without limitation.

The limiting assembly includes a limiting gear 12, a limiting rack 13, a first connecting rod 14, a first spring 15 and a first fixing plate 16. The limiting gear 12 is fixed on one end of the rotating roller 7 and located close to the hand wheel 8;

The limiting gear 12 is meshedly connected with a limiting rack 13, a first connecting rod 14 is fixed to one side of the limiting rack 13, a first fixing plate 16 is fixed to one side of the first connecting rod 14, a first spring 15 is fixed to one side of the first fixing plate 16, and one end of the first spring 15 is fixed to the inner wall of the electric cabinet body 1.

The disassembly mechanism includes a first fixed block 18, a first sliding block 19, a second connecting rod 21, a second fixed plate 22 and a second spring 23. A first sliding plate 17 is provided outside the cooling fan 5, and the first sliding plate 17 is rotatably connected to the cooling fan 5.

The top and bottom of the first sliding plate 17 are fixedly connected with a first fixed block 18, the first fixed block 18 cooperates with the first sliding block 19, the first sliding block 19 is fixedly connected with a second connecting rod 21, the second connecting rod 21 is fixedly connected with a second fixed plate 22, the second fixed plate 22 is fixedly connected with a second spring 23, and the second spring 23 is fixed to the inner wall of the electric cabinet body 1.

In this embodiment, the first sliding block 19 is processed into an arc-shaped surface 20 , and the arc-shaped surface 20 of the first sliding block 19 is buckled with the first fixing block 18 .

The design of the disassembly mechanism facilitates the repair and replacement of the cooling fan 5. When the cooling fan 5 is damaged, the cooling fan 5 can be directly taken out for repair or replaced with a new cooling fan 5, ensuring that the control cabinet can be put into use quickly and ensuring the safety of the instruments inside the control cabinet.

In an embodiment, the use process of a control cabinet is as follows: the user pulls the first fixed plate 16 to one side, and the movement of the first fixed plate 16 drives the first connecting rod 14 to move. At this time, the first spring 15 fixed to the first fixed plate 16 is compressed, and the limiting rack 13 no longer limits the limiting gear 12 after movement, so that the rotating roller 7 fixed to the limiting gear 12 can rotate freely.

The user rotates the hand wheel 8. Since the hand wheel 8 is fixedly connected to the rotating roller 7, the rotation of the hand wheel 8 drives the rotating roller 7 to rotate, so that the two first bevel gears 9 fixed to the rotating roller 7 also rotate. Since the first bevel gear 9 is meshingly connected with the second bevel gear 10, the rotation of the first bevel gear 9 drives the second bevel gear 10 to rotate, so that the bidirectional threaded rod 11 fixed to the second bevel gear 10 also rotates.

Since the two placement plates 6 are threadedly connected to the two bidirectional threaded rods 11, the rotation of the bidirectional threaded rods 11 causes the two placement plates 6 to move away from each other. At this time, the placement space inside the electric cabinet body 1 is adjusted so that instruments of different sizes can be placed inside the electric cabinet body 1.

When the cooling fan 5 needs to be repaired or is damaged, the user moves the two second fixing plates 22 away from each other. At this time, the first sliding block 19 no longer restricts the first fixing block 18, so that the first sliding plate 17 fixed to the first fixing block 18 can be taken out. At this time, the cooling fan 5 rotatably connected to the first sliding plate 17 can be repaired or replaced.

When the repair or replacement is completed, the user repositions the first sliding plate 17 inside the electric cabinet body 1. At this time, the first fixed block 18 contacts the arc surface 20. Since the first sliding block 19 is slidingly connected to the electric cabinet body 1, the first fixed block 18 is pushed upward by the first sliding block 19. At this time, the movement of the first sliding block 19 drives the second connecting rod 21 to move, so that the second fixed plate 22 fixed to the second connecting rod 21 also moves. Since the second fixed plate 22 is fixed to the two second springs 23, the movement of the second fixed plate 22 compresses the second springs 23. When the first sliding plate 17 is placed in a suitable position, the first fixed block 18 is no longer in contact with the arc surface 20. Under the action of the elastic force of the second springs 23, the two first sliding blocks 19 are reset to the first fixed block 18. At this time, the first sliding plate 17 is re-fixed inside the electric cabinet body 1.

The design of the disassembly mechanism facilitates the repair and replacement of the cooling fan 5. When the cooling fan 5 is damaged, the cooling fan 5 can be directly taken out for repair or replaced with a new cooling fan 5, ensuring that the control cabinet can be put into use quickly and ensuring the safety of the instruments inside the control cabinet.

The embodiment described above is only one of the more preferred specific implementation methods of the utility model. Common changes and substitutions made by technicians in this field within the scope of the technical solution of the utility model should be included in the protection scope of the utility model.
