Likewise, one end of the second fixing plate 5 may be provided with a second mounting portion 53. A support column 6 is provided between the first mounting portion 43 and the second mounting portion 53.

Referring to fig. 1 and 2, in an alternative embodiment, the cable fixing device may further include a lifting assembly, which is mounted at the bottom of the second fixing plate 5 and is used for driving the wire arranging assembly to ascend or descend. The second fixing plate 5 is located below the first fixing plate 4. In particular, since the bridge 2 is arranged above the cabinet, the height of the bridge remains unchanged. There may be a plurality of cabinets 1 disposed below the bridge 2, and the heights of the plurality of cabinets 1 may be different (only the cabinets having the same height are shown in the figure). The lifting assembly can adjust the height of the wire arranging assembly according to the height of the specific cabinet 1, so that the wiring terminal between the first cable 301 and the second cable 302 after being plugged is located between the first fixing plate 4 and the second fixing plate 5, and therefore the plugging reliability of the wiring terminal is improved.

In an alternative embodiment, the lifting assembly may include a first support rod 7, a second support rod 8 and a first sliding mechanism, wherein the first support rod 7 and the second support rod 8 are arranged in a crossed manner and connected through a rotating shaft 9. The lower ends of the first support rod 7 and the second support rod 8 are respectively connected with a first sliding mechanism, and the first sliding mechanism drives the first support rod 7 and the second support rod 8 to rotate along a rotating shaft 9. Specifically, the first sliding mechanism can drive the first support rod 7 and the second support rod 8 to rotate along the rotating shaft 9, so that the lower ends of the first support rod 7 and the second support rod 8 are close to or far away from each other, and the first support rod 7 and the second support rod 8 are raised or lowered in the height direction.

In a specific embodiment, the first sliding mechanism includes a sliding slot 10, a first threaded sleeve 11, a second threaded sleeve 12 and a threaded rod 13. A first threaded sleeve 11, a second threaded sleeve 12 and a threaded rod 13 are arranged in the slide 10. The two ends of the screw 13 are respectively provided with a first thread portion 131 and a second thread portion 132 with opposite thread directions, the first thread portion 131 is sleeved with the first thread sleeve 11, and the second thread portion 132 is sleeved with the second thread sleeve 12. The first threaded sleeve 11 has threads that intermesh with the threads of the first threaded portion 131. The second threaded sleeve 12 has threads that intermesh with the threads of the second threaded portion 132. The first support rod 7 is connected with a first threaded sleeve 11, and the second support rod 8 is connected with a second threaded sleeve 12. Turning the screw 13 drives the first and second threaded

sleeves

11, 12 towards or away from each other. Specifically, the first support bar 7 is pivotally connected to the first threaded sleeve 11, and the second support bar 8 is pivotally connected to the second threaded sleeve 12. Since the first thread part 131 and the second thread part 132 at both ends of the screw 13 have opposite thread directions, when the screw 13 is rotated, the first thread sleeve 11 and the second thread sleeve 12 move in opposite directions, so that the lower end of the first support rod 7 and the lower end of the second support rod 8 move in opposite directions. That is, the lower end of the first support bar 7 and the lower end of the second support bar 8 are close to or far away from each other by the first threaded sleeve 11 and the second threaded sleeve 12. When the lower ends of the first support rod 7 and the second support rod 8 are close to each other, the lifting assembly is lifted. When the lower end of the first support rod 7 and the lower end of the second support rod 8 are far away from each other, the lifting assembly descends.

It should be noted that the first thread part 131 and the second thread part 132 are located at both ends of the screw 13 and spaced apart from each other. Therefore, there is a limit to the sliding distance between the first and

second thread bushes

11 and 12, so that the first and

second thread bushes

11 and 12 slide only on the thread portions. Therefore, the first and

second screw bosses

11 and 12 do not contact each other and the first and second support bars 7 and 8 do not coincide with each other. The lengths of the first thread part 131 and the second thread part 132 may be calculated according to the height of the cable fixing device to be lifted, and the present application is not particularly limited thereto.

Fig. 3 is a schematic structural diagram of a cable fixing device in another embodiment of the present application. In an alternative embodiment, as shown in fig. 3, the lifting assembly may further include a second sliding mechanism, and the second sliding mechanism is mounted at the bottom of the second fixing plate 5. The second sliding mechanism comprises a sliding block 14, a fixed block 15 and a sliding rail 16, the fixed block 15 is fixed at one end of the sliding rail 16, the sliding block 14 is connected with the first supporting rod 7, the fixed block 15 is connected with the second supporting rod 8, and the sliding block 14 is driven by the first supporting rod 7 to slide along the sliding rail 16. Specifically, the second sliding mechanism is mounted on the bottom of the second mounting portion 53. The upper end of the first support rod 7 is pivotally connected with the slide block 14, and the upper end of the second support rod 8 is pivotally connected with the fixed block 15. The slide rail 16 extends in the same direction as the slide groove 10. When the first sliding mechanism drives the lower end of the first support bar 7 and the lower end of the second support bar 8 to approach or separate from each other, the upper end of the second support bar 8 rotates relative to the fixing block 15, the upper end of the first support bar 7 rotates relative to the flower opening 14, and the upper end of the first support bar 7 drives the slider 14 to move on the slide rail 16, so that the upper end of the first support bar 7 and the upper end of the second support bar 8 approach or separate from each other.

In an alternative embodiment, a through hole is provided at one end of the sliding chute 10, and one end of the screw 13 extends from the through hole 101 to the outside of the sliding chute 10. Specifically, the through hole 101 may be opened in the sliding groove 10 toward the direction operated by the operator, for example, near the cabinet door side of the cabinet. One end of the screw 13 is an a-end extending from the through hole 101 to the outside of the chute 10. At the a-end a fixing pin 17 can be attached. The worker can screw the fixing pin 17 by hand to rotate the screw 13.

In another alternative embodiment, a motor (not shown in the figures) may be further connected to the end a of the screw 13 to achieve automatic rotation of the screw 13, so as to adjust the lifting height of the lifting assembly.

Referring to fig. 3, in an alternative embodiment, the lifting assembly is disposed at one end of the second fixing plate 5. The cable fixing device may further include a supporting component disposed at an end of the second fixing plate 5 away from the lifting component. The supporting component comprises a telescopic rod 19 and a supporting spring 18, the supporting spring 18 is sleeved on the periphery of the telescopic rod 19, and the telescopic direction of the telescopic rod 19 is consistent with the lifting direction of the lifting component. Specifically, the telescopic rod 19 may include a sleeve 191 and a sliding rod 192, the sleeve 191 is sleeved on an outer wall of the sliding rod 192, and the sliding rod 192 is slidably connected to the sleeve 191. The bottom end of the sleeve 191 is connected with the cabinet, and the top end of the sliding rod 192 is connected with the second fixing plate 5. The lifting assembly drives the wire management assembly up and down, thereby moving the slider 192 downward relative to the sleeve 191. When the wire harness assembly moves downward, the supporting spring 18 is compressed and tends to rebound, and the supporting spring 18 has an upward supporting force on the second fixing plate 5. The lifting assembly and the supporting assembly carry out three-point support on the wire arranging assembly, so that the cable fixing device is stable.
