[0020] The guide assembly 3 includes a limit unit and a docking unit. The limit unit is used to separate the bending part of the cable 4 from the inner corner of the four-way bridge connection seat 1 to avoid damage caused by contact and friction between the cable 4 and the inner corner of the four-way bridge connection seat 1. The docking unit is used to realize the vertical assembly of two groups of limit units to form upper and lower layers for multiple cables 4.

[0021] The limiting unit includes a guide roller 301 , a limiting plate 302 , a hexagonal top block 303 , a connecting column 304 , a threaded column 305 , and a nut 307 . The limit plate 302 is fixed on the top of the guide roller 301, and the hexagonal top block 303, the connecting column 304, and the threaded column 305 are distributed and fixed in sequence along the vertical direction, and the hexagonal top block 303 is located at the top of the limit plate 302, the connecting column 304 passes through the limit plate 302 and the guide roller 301 and is rotatably connected with the limit plate 302 and the guide roller 301, and the threaded column 305 protrudes to the bottom of the guide roller 301; the threaded column 305 passes through the straight slot 2 to the bottom of the four-way bridge connection seat 1, and two nuts 307 are threadedly connected to the outside of the threaded column 305 and fit the upper and lower surfaces of the four-way bridge connection seat 1, which are used to realize the installation and fixation of the guide roller 301 and the limit plate 302; the guide roller 301 is used to form a support for the inner side of the bending part of the cable 4, so as to realize the separation of the cable 4 and the corner of the four-way bridge connection seat 1; the limit plate 302 is fit to the upper surface of the cable 4, which is used to limit the vertical direction of the cable 4.

[0022] The docking unit includes a threaded hole 306 and a docking slot 308; the threaded hole 306 is opened at the top of the hexagonal top block 303 and penetrates into the interior of the connecting column 304, and the threaded hole 306 is used for threaded connection of the threaded column 305 in the second group of limiting units; the docking slot 308 is opened at the bottom of the guide roller 301, which is used to make the guide roller 301 in the second group of limiting units sleeved with the hexagonal top block 303; the radius difference between the limit plate 302 and the guide roller 301 is greater than the outer diameter of the cable, and the limit plate 302 located at the bottom is used to form a support for the bottom of the cable above.

[0023] In this embodiment, it should be supplemented that the four-way bridge connection seat 1 is used to connect with the straight bridge, and the four-way bridge connection seat 1 can realize the diversion or merging of the direction of the cable 4.

[0024] When laying the cable 4, the corresponding guide assembly 3 can be installed according to the direction of the cable 4, and the installation operation is as follows:

[0025] First, the first nut 307 is threadedly connected to the threaded column 305, and the nut 307 is continuously rotated to make it enter the docking slot 308 until the bottom of the nut 307 slightly protrudes from the bottom of the guide roller 301 (such as Figure 3 ).

[0026] Then install the guide assembly 3 above the straight slot 2 at the corresponding position, so that the threaded column 305 passes through the straight slot 2 to the bottom of the four-way bridge connection seat 1. At this time, the bottom of the first nut 307 is attached to the bottom of the inner wall of the four-way bridge connection seat 1.

[0027] Then, the second nut 307 is threadedly connected to the threaded column 305 and tightened to make it fit against the bottom of the four-way bridge connection seat 1. At this time, the component 3 is fixed inside the four-way bridge connection seat 1, and the bottom of the guide roller 301 does not contact the bottom of the inner wall of the four-way bridge connection seat 1.

[0028] When the cable 4 is turning, the inner side of the turning portion is in contact with the outer side of the guide roller 301, and the upper surface of the turning portion is in contact with the lower surface of the limit plate 302. In this way, when the cable 4 is pulled, the cable 4 will not contact the inner corner of the four-way bridge connection seat 1, effectively avoiding the wear and scratch of the cable 4. At the same time, the guide roller 301 and the limit plate 302 can rotate around the connecting column 304, which can effectively reduce the resistance of the cable 4 when it is pulled (it should be supplemented that the inner side of the guide roller 301 is formed with an annular protrusion, and the outer side of the connecting column 304 is formed with an annular groove for the rotation of the annular protrusion (see Figure 4 ), so that the polygonal top block 303 will not hinder the rotation of the limiting plate 302).

[0029] If there are a large number of cables in the same bending direction, they can be divided into upper and lower layers. At this time, another set of guide components 3 can be taken out and threadedly connected to the threaded holes 306 in the first set of guide components 3 through the threaded columns 305. At this time, the guide rollers 301 in the other set of guide components 3 are sleeved on the outside of the hexagonal top block 303 through the docking slots 308 (it should be noted that: at this time, there is a certain gap between the two guide rollers 301, and there will be no friction and interference with each other). Then, a cable is attached to the outside of the guide rollers 301 in the other set of guide components 3 to make a turn.

[0030] It should be further explained that the guide assembly 3 can also be used at other turning points of the cable bridge to ensure the safety of the turning points of the cable.

[0031] Please refer to Figures 2 to 4 The inner wall diameter of the docking slot hole 308 is larger than the circumscribed circle diameter of the hexagonal top block 303 , and the height of the docking slot hole 308 is larger than the height of the hexagonal top block 303 to match.

[0032] The inner diameter of the docking slot hole 308 is greater than the circumscribed circle diameter of the nut 307 , so that the nut 307 can enter the inner side of the docking slot hole 308 .

[0033] In this embodiment: the inner diameter of the docking slot 308 is larger than the circumscribed circle diameter of the hexagonal top block 303 and the nut 307, so that the outer walls of the hexagonal top block 303 and the nut 307 do not contact the inner wall of the docking slot 308, thereby ensuring the stable rotation of the guide roller 301.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
