[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A transformer variable frequency air-cooling control cabinet comprises a cabinet body 1 and a cabinet door rotatably connected to the outer wall thereof, a side of the cabinet body 1 close to the cabinet door is provided with an opening communicating with the interior thereof, a storage groove is provided at the inner bottom of the cabinet body 1, a support block 12 is slidably connected to the inner wall of the storage groove for supporting a mounting plate 2, an upper end of the support block 12 passes through the storage groove and is fixedly connected to a vertically arranged mounting plate 2 for mounting various components in the cabinet body 1, a second support rod 3 is slidably inserted on a side of the mounting plate 2 close to the opening for guiding and supporting the mounting plate 2, one end of the second support rod 3 passes through the mounting plate 2 and is fixed to the inner wall of the cabinet body 1;

[0022] In this embodiment, two transversely arranged first support rods 4 are slidably inserted in the support block 12, which are used to guide and support the support block 12. The two ends of the first support rod 4 respectively penetrate the support block 12 and are fixed on the inner sides of the storage groove. A slide groove is provided in the support block 12, and a slider 10 is slidably connected to the inner side wall of the slide groove to drive the block 11 to move. Arc grooves are provided on both sides of the slider 10, and balls are rollingly connected to the inner side wall of the arc groove to reduce the resistance of the slider 10 when it moves, and part of the ball passes through the arc groove;

[0023] In this embodiment, a card block 11 is fixedly connected to the lower end of the slider 10, which is used to cooperate with the card slot to lock the position of the support block 12. A card slot corresponding to the card block 11 is provided at the inner bottom of the storage slot. The lower end of the card block 11 slides through the support block 12 and slides into the card slot. The upper end of the slider 11 is fixedly connected to a spring 9 for elastically supporting the slider 10. The upper end of the spring 9 abuts against the inner top of the slide slot. The upper end of the slider 10 is slidably inserted with a connecting rod 8 for preventing the spring 9 from tilting. The upper end of the connecting rod 8 slides through the spring 9 and is fixed to the inner top of the slide slot.

[0024] In this embodiment, a pull rope 7 is fixedly connected to the upper end of the slider 10 for driving the slider 10 to move. A through hole corresponding to the pull rope 7 is provided on the side of the support block 12 facing the opening. A semi-circular handle 5 is fixedly connected to the side of the support block 12 facing the opening for facilitating the user to pull the support block 12 to move. A pull ring 6 is provided in the handle 5 for facilitating the user to pull the pull rope 7 to move.

A rubber pad is fixedly connected to the inner side wall of the pull ring 6 for improving the comfort of the pull ring 6 when in use. Wire wheels are provided on both sides of the pull rope 7 for improving the smoothness of the movement of the pull rope 7. The two ends of the wire wheels are rotatably connected to the inner sides of the slide groove respectively.

[0025] In this embodiment, the various components in the transformer variable frequency air-cooled control cabinet are first pre-installed through the mounting plate 2. During maintenance and repair, the pull rope 5 is first manually held, and then the finger is inserted into the pull ring 6 and pulled. The pull rope 7 is driven to move through the pull ring 6, and the slider 10 and the card block 11 are driven to move upward through the pull rope 7. At the same time, the handle 5 is manually pulled to drive the support block 12 to move, and the mounting plate 2 is driven to move toward the opening direction through the support block 12, so that the various components on the mounting plate 2 are moved to the opening, thereby reducing the difficulty of operation during maintenance and repair, and improving convenience and efficiency; when the slider 10 moves upward, the spring 9 is compressed. When the user releases the pull ring 6, the elasticity of the universal spring 9 pushes the slider 10 to move downward and reset. The slider 10 pushes the card block 11 to move downward and reset to the card slot, so that the support block 12 can be locked in position, thereby preventing the mounting plate 2 from shifting.
