The bottom of the top cover 2 is provided with an elastic fixing assembly for securing the wiring harness, and the interior of the side wall of the wire trough body 1 is provided with a locking assembly 7 for locking the top cover 2 after closing. In this embodiment, the provision of the elastic fixing assembly can not only secure the wiring harness but also provide a vibration reduction effect, thereby effectively preventing the connection between the wiring harnesses from being disconnected or the wiring harness from being broken. By providing the top cover 2 opening and closing assembly, the top cover 2 can always be in an open or closed state, cooperating with the elastic fixing assembly to secure the wiring harness within the wire trough body 1. When the top cover 2 is closed, the elastic fixing assembly secures the wiring harness; when the top cover 2 is opened, the elastic fixing assembly releases the wiring harness from being secured for easy maintenance. By providing the locking assembly 7, the upper cover 2 can be further locked after being closed, ensuring that the upper cover 2 is always in a closed state, and the elastic fixing assembly always fixes the wiring harness.

[0023] like Figure 2 、 Figure 3As shown, the opening and closing assembly of the upper cover 2 includes a tension spring 51, a first tension spring column 52 and a second tension spring column 53; the side wall of the wire trough body 1 is provided with a rotating platform 3, and the upper cover 2 is rotatably connected to the side wall of the wire trough body 1 through the rotating platform 3. The upper cover 2 is L-shaped, and the side wall of the rotating platform 3 is provided with a first tension spring column 52, and the side wall of the upper cover 2 is provided with a second tension spring column 53. A tension spring 51 is provided between the first tension spring column 52 and the second tension spring column 53; in this embodiment, the shape of the upper cover 2 is as shown Figure 2 As shown, the first tension spring column 52 and the second tension spring column 53 are arranged at positions as shown in FIG. Figure 3 As shown, a rotating shaft 74 is integrally formed at one end of the upper cover 2 where it connects to the rotating platform 3. The rotating platform 3 comprises two opposing fixed blocks with an opening coaxially positioned between them. The rotating shaft 74 at the end of the upper cover 2 is rotatably connected within the opening, allowing the upper cover 2 to rotate 180 degrees within the rotating platform 3. During use, the user opens the upper cover 2 to a certain angle, and the tension spring 51 pulls the upper cover 2 until it is fully open. The user then closes the upper cover 2 toward the trunking body 1 to a certain angle, and the tension spring 51 pulls the upper cover 2 to close on top of the trunking body 1.

[0024] like Figure 4 As shown, the elastic fixing assembly includes a slide rod 61, a pressing block 62 and a pressing spring 63; a sliding hole 64 is opened at the bottom of the upper cover 2, and the slide rod 61 is slidably connected in the sliding hole 64.

The end of the slide rod 61 located outside the sliding hole 64 is fixedly connected to the pressing block 62; in this embodiment, the shape of the slide rod 61 is as shown in FIG. Figure 4 As shown, the end of the slide rod 61 located in the sliding hole 64 is integrally formed with an annular flange, which ensures that the slide rod 61 will not fall out of the sliding hole 64. When in use, the upper cover 2 is closed, and the clamping block 62 will contact the wire harness and apply pressure to the wire harness. It is worth noting that the clamping spring 63 should be in a semi-compressed state at this time, so that the wire harness can be fixed in the wire trough body 1 through the clamping block 62, and the further elastic deformation of the clamping spring 63 can provide a vibration reduction effect for the wire harness when the vibration is large. Preferably, the shape of the clamping block 62 is arc-shaped, and its curvature is slightly larger than the curvature of the wire harness. The shape of the clamping block 62 matches the wire harness to more firmly fix the wire harness in the wire trough body 1. Preferably, the upper cover 2 opening and closing assembly, the upper cover 2 and the elastic fixing assembly can be provided in multiple groups to fix the wire harness from multiple different positions of the wire trough body 1.

The slide groove 77 is in the shape of a circular arc, and the slide groove 77 can slide along the slide groove 77. When in use, the slider 76 is moved to the left, the locking spring 72 is compressed, and the limit pin 71 is released from the locking groove 75, at which point the upper cover 2 can be opened or closed; after the upper cover 2 is closed, the slider 76 is released, and the locking spring 72 pushes the limit pin 71 back to its original position, cooperating with the locking groove 75 to lock the upper cover 2.

[0026] like Figure 1 、 Figure 2 As shown, a plurality of branch line grooves 4 for collecting wire harnesses into the wire groove body 1 are integrally formed on the side wall of the wire groove body 1. In this embodiment, by adding branch line grooves 4, multiple signal lines can be collected into the wire groove body 1 to form a wire harness.

[0027] The implementation principle of the embodiment of the present utility model is:

[0028] Place the wiring harness into the wiring duct body 1 and funnel the wiring harness into the wiring duct body 1 through the branch wiring duct 4 .

[0029] After the wiring harness is placed, the slider 76 is moved to the left, the locking spring 72 is compressed, the limit pin 71 is slightly deflected to the right, and the upper cover 2 is closed to a certain angle toward the wiring trough body 1. The tension spring 51 pulls the upper cover 2 to cover the top of the wiring trough body 1.
