[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] like Figures 1-4 As shown, this embodiment provides a cable fixing device for cable shafts, including a fixed support plate 1 with several supports, a bracket 2 erected between two adjacent supports, and cable fixing clips detachably installed on the bracket 2. The cable fixing clips include a first clip 3 that snaps into the bracket 2 and a second clip 4 that is detachably connected to the first clip 3. The cable fixing clips can be selectively installed at preset positions on the bracket to adapt to different cable layout requirements within the cable shaft.

[0044] In this embodiment, multiple fixed support plates 1 are arranged on the inner wall of the cable shaft. The fixed support plates 1 are vertically installed on the wall of the cable shaft, and each fixed support plate 1 is parallel to the others. Two rows of first through holes 11 are opened on the fixed support plates 1, and the fixed support plates are fixed to the wall of the cable shaft by expansion bolts or other fasteners. A bracket 2 is erected between two adjacent fixed support plates 1.

[0045] Specifically, multiple sets of supports are arranged on the fixed support plate, each support being positioned between two rows of first through holes 11 on the fixed support plate. Two parallel supports are used to support the bracket 2. Each support includes upper supports 5 and lower supports 6 spaced apart, meaning there is a gap between the upper supports 5 and the lower supports 6. The supports are connected; for example, the lower support 6 of the upper support and the upper support 5 of the lower support are connected or integrated. More specifically, the upper support 5 comprises three horizontally arranged upper plates 51 at equal intervals. Each upper plate 5 has several second through holes 511 arranged in a rectangular matrix. Adjacent upper plates 51 form a support space 52 for supporting the bracket 2. The lower support 6 is a lower plate located directly below the middle upper plate 51 of the upper support 5. The lower support 6 has several third through holes 61 arranged in a rectangular matrix.

[0046] An auxiliary clamping plate 7 is provided between the upper support 5 and the lower support 6, such as... Figure 1 , Figure 4 and Figure 6 As shown, the auxiliary clamping plate 7 includes an integral upper plate 71, a flat plate 72, and a lower plate 73. The upper plate 71 is located on the upper right side of the flat plate 72, and the lower plate 73 is located on the lower left side of the flat plate 72. The upper plate 71 and the lower plate 73 are arranged vertically, while the flat plate 72 is arranged horizontally. When the auxiliary clamping plate 7 is fixed, the flat plate 72 is located in the gap between the upper support 5 and the lower support 6, and is used to fix the auxiliary bracket. The upper plate 71 abuts against the side of the upper support 5; the lower plate 73 abuts against the side of the lower support 6, that is, the upper plate 71 and the lower plate 73 are on different sides, respectively located on both sides of the support assembly. The upper plate 71 has an upper through hole 711 that matches the second through hole 511 of the upper vertical plate 51, and the lower plate 73 has a lower through hole 731 that matches the third through hole 61 of the lower vertical plate. Bolts are used to pass through the corresponding holes for fixing.

[0047] In this embodiment, as Figure 4 and Figure 5As shown, the bracket 2 includes a portal frame 21 and a frame plate 22. The frame plate 22 is fixed to the front side of the portal frame 21, and the top of the frame plate 22 is higher than the top of the portal frame 21. The protruding part is used to engage the first clip 3. The frame plate 22 has several fourth through holes 221 for detachably connecting the first clip 3 and the second clip 4. The two side legs of the portal frame 21 are embedded in the mounting space 52 of the upper support 5. The legs have fifth through holes 211 that match the second through holes 511 of the upper support 5. After the bracket 2 is mounted on the support, it is fixed by bolts passing through the corresponding through holes. This fixing method is convenient for disassembly and operation.

[0048] In this embodiment, the cable fixing clips that can be detachably installed on the bracket 2 include a first clip 3 and a second clip 4. For example... Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, the first clamping member 3 includes a clamping part 31 for clamping onto the frame plate 22. The clamping part 31 is a plate-shaped structure with a downward-facing opening groove. The front side of the first clamping member 3 includes a first cable groove 32, which includes multiple semi-circular grooves. The second clamping member 4 includes a second cable groove 41 and connecting plates 42 on both sides thereof. The second cable groove 41 is adapted to the first cable groove 32, and the second cable groove 41 together with the first cable groove 32 is used to accommodate cables.

[0049] Furthermore, the first clip 3 has a sixth through hole 33 that matches the fourth through hole 221 of the bracket 2; the second clip 4 has a seventh through hole 43 that matches the fourth through hole 221 of the bracket 2; by using bolts to pass through the corresponding seventh through hole 43, sixth through hole 33 and fourth through hole 221, the cable fixing clip can be installed on the bracket 2.

[0050] Furthermore, the front side of the first clip 3 is also fixedly connected to a limiting block 34; correspondingly, the connecting plate 42 of the second clip 4 is provided with a limiting groove 44 that is adapted to the limiting block 34.

[0051] When fixing cables inside the cable shaft, the first clamp 3 is temporarily mounted on the support plate 22. The clamping part 31 of the first clamp 3 is engaged with the upper end of the support plate 22 in the bracket 2. At this time, there is no need to hold the first clamp 3 by hand, and the first clamp 3 will not detach from the bracket 2 on its own, which facilitates subsequent operations. Then, the cable is placed into the first cable trough 32, and then the second clamp 4 is fastened onto the cable. At the same time, the limiting groove 44 of the second clamp 4 engages with the limiting block 34 of the first clamp 3. At this time, the first cable trough 32 and the second cable trough 41 together form a space for accommodating the cable. In order to avoid wear on the cable, rubber pads are also attached to the inner walls of the first cable trough 32 and the second cable trough 41. The rubber pads are provided with several protrusions, which not only prevent cable wear but also increase friction and prevent the cable from moving downward. At this time, the seventh through hole 43 of the second clip 4 coincides with the sixth through hole 33 of the first clip 3. Adjust their positions and make the seventh through hole 43 and the sixth through hole 33 coincide with the fourth through hole 221 of the bracket plate 22 in the bracket 2. Fix them with bolts to achieve the fixing of the cable fixing clip on the bracket 2.

[0052] The cable fixing device for cable shafts provided in this embodiment has a fixing support plate 1 vertically installed on the wall of the cable shaft and fixed by expansion bolts or other fasteners, serving as the foundation for fixing the cable. A bracket 2 is erected between two adjacent fixing support plates 1, wherein the two legs of the portal frame 21 are engaged in the upper support 5. Bolts are used to pass through the second through hole 511 of the upper support 5 and the fifth through hole 211 of the portal frame 21, detachably connecting the portal frame 21 to the support of the fixing support plate, thus fixing the entire bracket 2 to the support. The two side legs of the portal frame 21 of the bracket 2 are embedded in the mounting space 52 in the upper support 5, resulting in a stable structure that can better bear the weight of the cable. An auxiliary clamping plate 7 is located between the upper support 5 and the lower support 6, used to assist in fixing the bracket. The auxiliary clamping plate 7 is fixed by bolts passing through the upper through hole 711 and the lower through hole 731. In the bracket 2, the top of its frame plate 22 is higher than the top of the portal frame 21, used to engage the first clamping piece 3. When fixing the cable, firstly, the first clamp 3 is placed on the frame plate 22, then the cable is placed into the first cable groove 32, and then the second clamp 4 is fastened onto the cable. Simultaneously, the limiting groove 44 of the second clamp 4 engages with the limiting block 34 of the first clamp 3. At this point, the first cable groove 32 and the second cable groove 41 together form a space to accommodate the cable. The first clamp 3 is engaged with the frame plate 22, and the second clamp 4 is detachably connected to the first clamp 3, so that the seventh through hole 43 and the sixth through hole 33 coincide with the fourth through hole 221 of the frame plate 22 in the bracket 2. Bolts are used for fixing, thus fixing the cable fixing clamp on the bracket 2. Since the frame plate 22 has several fourth through holes 221 for fixing the cable fixing clamp, the cable fixing clamp can be fixed at the corresponding appropriate position of the fourth through hole 221 according to the actual working conditions, adapting to different layout requirements and offering flexible and convenient operation.

[0053] The cable fixing device for cable shafts provided in this embodiment allows the first clip 3 of the cable fixing clips to be directly clipped onto the bracket plate 22 when fixing the cable. After the cable is placed in the cable trough, the second clip 4 is then installed. This not only makes the operation simple, but also eliminates the need to hold the first clip 3 by hand when installing it. The first clip 3 will not detach from the bracket 2 on its own, ensuring reliable fixing and facilitating subsequent operations.

[0054] The cable fixing device for cable shafts provided in this embodiment uses bolts to fix the bracket 2 and the support. The bracket 2 and the cable fixing clip are also fixed by bolts passing through the corresponding through holes. This fixing method is easy to install and dismantle and convenient to operate.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
