[0021] This application discloses a frequency converter control cabinet with an internal wiring mechanism. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4The frequency converter control cabinet with internal wiring mechanism includes a cabinet body 1 and a cabinet door 11 hinged to the cabinet body 1. A vertical plate 2 is fixedly connected inside the cabinet body 1. There is one vertical plate 2 on each of the inner sides of the cabinet body 1. The vertical plate 2 is set along the height direction of the cabinet body 1. The two vertical plates 2 are connected to the mounting plate 21 by bolts. Electrical equipment can be connected to the mounting plate 21. A guide rail 3 is fixedly connected to the mounting plate 21. The guide rail 3 is set along the height direction of the mounting plate 21. There is one guide rail 3 on each of the opposite sides of the mounting plate 21. Several sliders 31 are slidably set on the guide rail 3 (only one is shown in the figure, but not limited to one). The slider 31 is provided with a locking component 4 for fixing the slider 31 to the guide rail 3. A wiring frame 5 is connected to the slider 31. The wiring frame 5 is set in the shape of "U". Wiring grooves 52 are opened on the wiring frame 5. Several wiring grooves 52 are evenly arranged along the length direction of the wiring frame 5.

[0022] The guide rail 3 is T-shaped, and the slider 31 has a groove that fits the guide rail 3. The matching design of the T-shaped guide rail 3 and the slider 31 groove enhances the guidance and stability during the sliding process and prevents the wiring frame 5 from shifting.

[0023] The locking assembly 4 includes a mounting cylinder 41, a cylinder cover 42, a locking rod 43, a sliding plate 44, a return spring 45, and a lever 46. The mounting cylinder 41 is fixedly connected to the slider 31 and is arranged perpendicular to the side wall of the slider 31. The cylinder cover 42 is connected to the opening of the mounting cylinder 41. The locking rod 43 passes through the cylinder cover 42, the mounting cylinder 41, and the slider 31 in sequence. The axis of the locking rod 43 is collinear with the axis of the mounting cylinder 41. The cylinder cover 42, the mounting cylinder 41, and the slider 31 are all provided with through holes for the locking rod 43 to pass through. The guide rail 3 has an adjustment hole for the locking rod 43 to be inserted. Several adjustment holes are evenly arranged along the length of the guide rail 3. The sliding plate 44 is fixedly connected to the rod of the locking rod 43 located inside the mounting cylinder 41. The side wall of the sliding plate 44 slides against the inner wall of the mounting cylinder 41. The return spring 45 is sleeved on the rod of the locking rod 43 located inside the mounting cylinder 41. One end of the return spring 45 abuts against the sliding plate 44, and the other end abuts against the bottom of the mounting cylinder 41. The lever 46 is connected to the end of the locking rod 43 that is not inserted into the mounting cylinder 41.

[0024] The locking rod 43 is provided with a rounded corner, which is located at the end of the locking rod 43 that is inserted into the locking hole. By providing the rounded corner, the locking rod 43 does not need to be perfectly aligned when it is inserted into the adjustment hole on the guide rail 3, which helps to improve installation efficiency.

[0025] The slide plate 44 is a square plate, and the inner cavity of the mounting cylinder 41 is adapted to the slide plate 44. By setting the slide plate 44 to a square plate, the locking rod 43 can be prevented from rotating, which helps to improve the stability of the locking rod 43 during movement.

[0026] Limiting blocks 211 are bolted to the mounting plate 21. There is one limiting block 211 at each end of the guide rail 3. When installing other sliders 31, the limiting blocks 211 can be removed, and then the additional sliders 31 can be installed on the guide rail 3 by sliding. After that, the limiting blocks 211 can be installed to limit the two ends of the guide rail 3.

[0027] The implementation principle of a frequency converter control cabinet with an internal wiring mechanism in this application embodiment is as follows: the sliding cooperation design of the guide rail 3 and the slider 31 allows the wiring rack 5 to move freely along the height direction of the mounting plate 21. Users can dynamically adjust the position of the wiring rack 5 according to actual wiring needs, avoiding the waste of space of fixed wiring racks. At the same time, the wiring rack 5 is distributed on both sides of the mounting plate 21 rather than in the center, freeing up the central area of ​​the mounting plate 21, significantly increasing the installation space of electrical equipment, and optimizing the layout efficiency inside the cabinet.

[0028] When moving the wiring rack 5, the operator pulls the lever 46 outward to disengage the locking lever 43 from the adjustment hole of the guide rail 3. At this time, the slider 31 can be moved up and down to adjust the height of the wiring rack 5 on the guide rail 3. After reaching the appropriate position, the lever 46 is released, and the return spring 45 pushes the slide plate 44 to drive the locking lever 43 into the adjustment hole of the guide rail 3. The operator can move the slider 31 by himself without the aid of external tools using the locking component 4, which shortens the adjustment time and improves the operating efficiency.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
