When it is necessary to adjust the mounting beam 2 When the mounting beam 2 is in the proper position, the winding roller 7 is rotated by the adjusting mechanism. When the winding roller 7 rotates, the two traction ropes 8 are wound around the winding roller 7. When the traction ropes 8 are wound around the winding roller 7, the other end of the traction ropes 8 pulls the clamping column 4, thereby causing the clamping column 4 to slide from the inside of the slave clamping slot 31 to the inside of the main clamping slot 3. This is to release the clamping connection between the clamping column 4 and the slave clamping slot 31 and the mounting beam 2. The operator can move the mounting beam 2 up and down to a suitable position. After the mounting beam 2 is moved to a suitable position, the winding roller 7 is rotated in the opposite direction by the adjusting mechanism to release the clamping column 7 from the mounting beam 2. The winding and wrapping of the traction rope 8 releases the tension of the two traction ropes 8 on the clamping column 4. The two clamping columns 4 are reset and re-inserted into the corresponding slave clamping slots 31 under the action of the elastic force of the spring 5, so that the mounting beam 2 is stabilized by the clamping column 4 again.

[0025] Furthermore, limiting rods 13 are symmetrically fixedly installed at both ends of the card column 4, and a main limiting groove 14 connected to the limiting rod 13 for limiting sliding is provided on the inner wall of the main card slot 3, and a plurality of slave limiting grooves 141 connected to the limiting rod 13 for limiting sliding are also provided on the inner walls of the plurality of slave card slots 31; when the card column 4 slides in the main card slot 3 and the slave card slot 31, the limiting rod 13 also slides in the corresponding main limiting groove 14 and slave limiting groove 141, and the limiting rod 13, the main limiting groove 14 and the slave limiting groove 141 prevent the card column 4 from rotating in the main card slot 3 and the slave card slot 31 to affect the clamping effect.

[0026] Furthermore, the rotating shaft 11 slides through the inner bottom wall of the adjusting groove 10 , and a rotating handle 15 is fixedly installed at the bottom end of the rotating shaft 11 ; the rotating handle 15 makes it easier for an operator to rotate the rotating shaft 11 .

[0027] Furthermore, a groove 16 is provided on the winding roller 7, and a clamping ring 17 is fixedly installed on the inner top wall of the winding groove 6. The ends of the two traction ropes 8 close to the winding roller 7 are both movable through the clamping ring 17; the groove 16 makes it difficult for the traction rope 8 to slide and fall off when being wound and wound, thereby affecting the winding effect, and the traction rope 8 is movable through the clamping ring 17 during the winding and winding process, so that the traction rope 8 is in a vertical state with the winding roller 7 when winding, and the traction rope 8 can be wound in a normal state and will not fall off from the winding roller 7 due to the angle problem on both sides.

[0028] Furthermore, slide grooves 19 are fixedly installed at the four corners of both ends of the mounting beam 2, and slide grooves 19 are respectively opened on the relative inner walls of the frequency conversion control cabinet body 1 to be slidingly connected to each slide rod 18; when the mounting beam 2 slides up and down in the frequency conversion control cabinet body 1, the slide rods 18 at both ends of the mounting beam 2 also slide up and down in the corresponding slide grooves 19, making it easier for the card column 4 to slide from the main card slot 3 into the corresponding slave card slot 31.

After the mounting beam 2 is moved to a suitable position, the rotating shaft 11 is rotated in the opposite direction by the turning handle 15, and then the winding roller 7 is rotated in the opposite direction by the slave bevel gear 12 and the main bevel gear 9, so as to release the winding roller 7 from winding up the traction rope 8, thereby releasing the stretching of the two traction ropes 8 on the clamping column 4. The two clamping columns 4 are reset under the action of the elastic force of the spring 5 and re-clamped into the corresponding slave clamping groove 31, so that the mounting beam 2 is stabilized by the clamping column 4 again, and the mounting beam 2 is limitedly installed by sliding the clamping column 4 in the main clamping groove 3 and the slave clamping groove 31, so that the operator can adjust the height of the mounting beam 2 according to the component to be installed, the operation is simple, and the installation difficulty of the mounting beam 2 is reduced, thereby avoiding the performance and stability of the frequency conversion control cabinet body 1 from being affected.
