It is related to the safety and stable operation of the electrical system as well as the subsequent maintenance and upgrade.

[0003] The existing frequency conversion control cabinet wiring trough is usually composed of a bottom trough and a cover plate. After searching, the publication number CN206401720U discloses that it is composed of a bottom trough, a cover plate and a trough frame. The bottom trough is a rectangular structure with an open top. A trough frame is welded and installed in the middle of the inner bottom of the bottom trough. The trough frames form a trough body. The cover plate is installed on the open part of the bottom trough. The cover plate is provided with a notch that matches the shape and position of the trough frame, so that the limited space in the control cabinet can be reasonably arranged.

[0004] However, in actual use, different wire troughs require different numbers and sizes of wire harnesses, and the space occupied by the wire harnesses is also different, resulting in waste or insufficient space in the wire harness trough, which will also affect the space utilization of the frequency conversion control cabinet.

[0007] The adjustment assembly includes an adjustment chassis and a rotating shaft, wherein the adjustment chassis is rotatably connected to the bottom plate, the rotating shaft is fixedly connected to the adjustment chassis, the adjustment chassis is evenly distributed with adjustment teeth, both ends of the clamping plate are fixedly connected with a connecting shaft, and one side of the connecting shaft is connected with a bite tooth adapted to the adjustment tooth;

[0008] The fixing assembly comprises a connecting plate rotatably connected to the rotating shaft, an adjusting screw and a fixing plate. The adjusting screw is rotatably connected to both ends of the connecting plate, and the fixing plate is rotatably connected to the adjusting screw via a rotating shaft on its side.

[0009] Further: both ends of the clamping plate are fixedly connected to the limiting plate 1, and the side of the clamping plate is provided with a plurality of limiting plates 2 arranged in an array.

[0010] Further: one end of the limiting plate 1 is adapted to the fixing plate, and the limiting plate 1 is elastic.

[0011] Further: the side surfaces of the limiting plate 1 and the fixing plate are hook-shaped.

[0012] Further: the second limiting plate is a rectangular hard plastic plate.

[0013] Further: the engaging teeth and the adjusting teeth are trapezoidal.

[0014] Furthermore: the length of the adjusting screw rod is half of the length of the connecting plate.

[0015] Compared with the prior art, the utility model has the following advantages: the utility model can adjust the spacing between the clamping plates on both sides of the bottom plate according to the number and size of the wiring harnesses that need to be placed in the wiring trough by setting an adjustment component, and fix it through a fixing component to avoid waste or insufficient space in the wiring harness trough.
