[0018] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. The parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, and how the cable is laid.

[0019] Example 1

[0020] A cable support for rail transit, such as Figure 1 and Figure 2 As shown, the system includes a column 2 and several brackets 1 detachably connected to the column 2. The column 2 is used for installation with external equipment to fix the overall cable bracket. Each bracket 1 is detachably equipped with multiple fixing components 4. The bracket 1 has multiple mounting holes 1011 distributed in a straight line. The fixing component 4 includes two parallel stops 402, which are connected to a baffle 401. The baffle 401 is arc-shaped and has a lifting ring 406. The lifting rings 406 of multiple fixing components 4 can be strung together with a connecting rope for easy carrying. A sleeve 404 is telescopically provided on the stops 402 to contact the surface of the bracket 1. One end of the sleeve 404 in contact with the surface of the bracket 1 is fixedly connected to an elastic buckle 405. The elastic buckle 405 passes through the mounting hole 1011 and contacts the lower surface of the bracket 1, so that the baffle 401, the two stops 402, and the bracket 1 together form a space 403 for accommodating the cable.

[0021] When it is necessary to fix the cable, simply place the cable on the support arm 1, and pass the elastic clips 405 on the two stops through the corresponding mounting holes 1011. Then adjust the extension range of the stop 402 and the sleeve 404 to achieve a suitable space 403 for accommodating the cable. By changing the size of the space 403, different types of cables can be accommodated. The operation is simple during production and processing, and the assembly process is easy. The width of the elastic clip 405 is larger than the diameter of the mounting hole 1011. The material of the elastic clip 405 is conventional technology in this field and will not be described in detail here.

[0022] The column 2, bracket 1, stop bar 402, baffle 401 and lifting ring 406 are all made of Q235 carbon structural steel, which has good strength and plasticity. The surfaces of the column 2, bracket 1, stop bar 402, baffle 401 and lifting ring 406 are all hot-dip galvanized for corrosion protection, which improves the corrosion resistance and service life of the components.

[0023] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0024] Example 2

[0025] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: a groove 4021 is formed along the axial direction of the stop rod 402, and an anti-detachment bolt 4041 extending into the groove 4021 is inserted through the sleeve 404. After the stop rod 402 slides to a suitable position within the sleeve 404, the anti-detachment bolt 4041 is pressed against the bottom wall of the groove 4021, fixing the position of the stop rod 402 within the sleeve. The baffle 401, the two stop rods 402, and the support arm 1 together form a fixed space 403 for accommodating the cable. The anti-detachment bolt 4041 only extends into the groove 4021 without contacting the bottom wall of the groove 4021, thus only preventing the stop rod 402 from detaching from the sleeve 404.

[0026] Example 3

[0027] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1. The improvement is that, in order to enhance the friction between the stop bar 402 and the cable and enhance the stability of the cable in the space 403, the stop bar 402 is wrapped with a friction layer.

[0028] Example 4

[0029] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: the elastic buckle 405 includes a connecting portion 4051 and a limiting portion 4052. The two ends of the connecting portion 4051 are respectively connected to the closed end of the sleeve 404 and the limiting portion 4052. The limiting portion 4052 contacts the surface of the support arm 1. The width of the connecting portion 4051 is smaller than the diameter of the mounting hole 1011, and the width of the limiting portion 4052 is larger than the diameter of the mounting hole 1011.

[0030] Example 5

[0031] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: the column 2 includes a first vertical plate 201 and a second vertical plate 202 that are perpendicular to each other. The first vertical plate 201 has several fixing holes 2011 along its length, through which bolts pass to fix it to external equipment. The second vertical plate 202 is connected to the support arm 1 by fixing bolts 3. The second vertical plate 202 has several connecting holes 2021 along its length. The support arm 1 has through holes, through which fixing bolts 3 pass sequentially through the through holes and one of the connecting holes 2021, and are then tightened by fixing nuts. The distance between the support arms 1 can be adjusted on-site according to actual conditions, and the number of support arms 1 can be increased as needed. The support arm 1 includes a first support plate 101 and a second support plate 102 that are perpendicular to each other. The mounting holes 1011 are located on the first support plate 101, and the through holes are located on the second support plate 102. This does not affect the cable fixing effect and allows for changing the position of the support arm 1.
