[0033] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The schematic diagram of the structure of the cable fixing device in one embodiment of the present application is shown. The cable fixing device provided in one embodiment of the present application includes a base 100, an upper pulley mechanism 200 and a lower pulley mechanism 300. The base 100 includes a bottom plate 130, a first side plate 110 and a second side plate 120. The first side plate 110 and the second side plate 120 are both connected to the bottom plate 130, and the first side plate 110 and the second side plate 120 are arranged with a relative interval. The first side plate 110 and the second side plate 120 are arranged on the same side of the bottom plate 130, and the three are arranged in a U-shaped structure. The first side plate 110 is provided with a first adjustment groove 110A, and the second side plate 120 is provided with a second adjustment groove 120A. The first adjustment groove 110A and the second adjustment groove 120A are arranged opposite to each other, and the two ends of the upper pulley mechanism 200 are movably arranged in the first adjustment groove 110A and the second adjustment groove 120A, respectively. The lower pulley mechanism 300 is arranged on the bottom plate 130, and the upper pulley mechanism 200 and the lower pulley mechanism 300 are arranged in an upper and lower spacing as a whole, and a cable threading channel is formed between the two, and the cable threading channel is used for threading cables.

[0034] Specifically, the first adjustment groove 110A is an arc groove or an oblique straight groove, and the two endpoints of the first adjustment groove 110A are respectively the highest point and the lowest point of the first adjustment groove 110A, and the second adjustment groove 120A is also an arc groove or an oblique straight groove, and the two endpoints of the second adjustment groove 120A are also respectively the highest point and the lowest point of the second adjustment groove 120A. Therefore, the height adjustment range of the upper pulley mechanism 200 is between the highest point and the lowest point of the two adjustment grooves, so that the upper pulley mechanism 200 can be close to or away from the lower pulley mechanism 300 by adjusting the position of the first adjustment groove 110A and the second adjustment groove 120A.

[0035] The cable fixing device described in the embodiment of the present application is used to fix cables, and the fixed cables are not limited to coaxial cables, and other types of cables can also be fixed. By installing the upper pulley mechanism 200 and the lower pulley mechanism 300 on the base 100, the two ends of the upper pulley mechanism 200 are respectively installed in the first adjustment groove 110A of the first side plate 110 and the second adjustment groove 120A of the second side plate 120. When the cable is installed between the upper pulley mechanism 200 and the lower pulley mechanism 300, by adjusting the position of the upper pulley mechanism 200 in the first adjustment groove 110A and the second adjustment groove 120A, the relative positions of the upper pulley mechanism 200 and the lower pulley mechanism 300 are adjusted, so that the upper pulley mechanism 200 and the lower pulley mechanism 300 can adapt to the sizes of different cables and fix the cables.

[0036] The cable fixing device described in the embodiment of the present application can adaptively fix the position of the cable through the upper pulley mechanism 200 and the lower pulley mechanism 300, and can fine-tune the fixing angle while fixing. The pulley fixing of the upper pulley mechanism 200 and the lower pulley mechanism 300 can also reduce the probability of scratches on the outer layer of the cable, and has the advantages of high convenience of use and good protection for the cable.

[0037] In an optional embodiment, if Figure 2 As shown, the bottom plate 130 is provided with a plurality of mounting holes 130A, and the first fastener is connected to the mounting surface through the mounting holes 130A, wherein the mounting surface is a plane for mounting the cable fixture. Since the cable fixture needs to be fixedly installed, a plurality of mounting holes 130A are provided on the bottom plate 130, and the first fastener is used to pass through the mounting holes 130A to be fixed to the mounting surface. In a specific example, the mounting surface is provided with a threaded countersunk hole, and the first fastener is a bolt or a screw, which passes through the mounting hole 130A and is fixedly connected to the threaded countersunk hole.

[0038] Combination Figure 3 As shown, Figure 3The cross-sectional view of the cable fixing device in an embodiment of the present application is shown. In some embodiments, the upper pulley mechanism 200 includes an adjusting rod 210 and a first pulley 220. The first pulley 220 is rotatably mounted on the adjusting rod 210, and the two ends of the adjusting rod 210 are respectively movably arranged in the first adjusting groove 110A and the second adjusting groove 120A. By rotatably mounting the first pulley 220 on the adjusting rod 210, setting the adjusting rod 210 at the position of the first adjusting groove 110A and the second adjusting groove 120A, the first pulley 220 abuts against the cable to fix the cable. Since the first pulley 220 can adaptively fix the cable, the cable can be fine-tuned according to the demand, and there is no need to worry about scratching the outer skin of the cable. Further, the first pulley 220 is detachable. By replacing the first pulley 220 of different sizes, cables of different sizes can be better fixed, which is convenient to use and has a good protection effect on the cable, and the operation flexibility is higher.

[0039] Furthermore, if Figure 2 and Figure 3 As shown, the two ends of the adjustment rod 210 are respectively provided with a first positioning portion 211 and a second positioning portion 212, the first positioning portion 211 is detachably connected to the first side plate 110, the first side plate 110 is also provided with a first circular notch 110C, the first circular notch 110C is communicated with one end of the first adjustment groove 110A, and the first circular notch 110C is used to remove or install the first positioning portion 211. Similarly, the second positioning portion 212 is detachably connected to the second side plate 120, the second side plate 120 is also provided with a second circular notch 120C, the second circular notch 120C is communicated with one end of the second adjustment groove 120A, and the second circular notch 120C is used to remove or install the second positioning portion 212. Since the upper pulley mechanism 200 is detachable, the adjusting rod 210 can be removed and replaced through the first circular groove 110C and the second circular groove 120C. After the adjustment is completed, both ends of the adjusting rod 210 are fixedly connected to the first side plate 110 and the second side plate 120 through the first positioning portion 211 and the second positioning portion 212 respectively, thereby fixing the cable.

[0040] Furthermore, if Figure 2 and Figure 3As shown, the first side plate 110 is provided with a plurality of first positioning holes 110B, the plurality of first positioning holes 110B are arranged at intervals along one side of the first adjustment slot 110A, the first positioning portion 211 is provided with a first connecting hole 211A, and the first connecting hole 211A is connected to any one of the first positioning holes 110B via a second fastener.

Since the adjustment rod 210 is adjustable, by setting a plurality of first positioning holes 110B along one side of the first adjustment slot 110A, and setting a plurality of second positioning holes 120B along one side of the second adjustment slot 120A, the first positioning portion 211 is connected to the corresponding first positioning hole 110B through the first connecting hole 211A and the second fastener, and the second positioning portion 212 is connected to the corresponding second positioning hole 120B through the second connecting hole and the third fastener, thereby achieving the adjustment and fixation of the adjustment rod 210, so that the cable can be fixed by the pulley while the fixing angle can be fine-tuned, making the fixing and use of the cable more convenient. In a specific example, the first positioning hole 110B and the second positioning hole 120B are threaded countersunk holes, and the second fastener and the third fastener are bolts or screws.

[0041] In an optional embodiment, if Figure 2 and Figure 3 As shown, the lower pulley mechanism 300 includes a guide sleeve base 310, an elastic member 320, a guide sleeve head 330 and a second pulley 340. The guide sleeve base 310 is arranged on the bottom plate 130. The guide sleeve base 310 is provided with a guide groove 310A. The guide sleeve head 330 is provided with a sliding portion 331.

When the cable is installed in the device, the cable abuts against the second pulley 340 on the guide sleeve head 330, and the elastic member 320 will apply a thrust to make the second pulley 340 tightly abut against the cable, ensuring that the second pulley 340 is fully in contact with the cable, and can provide upward pressure to make the cable abut against the first pulley 220, allowing the cable to rotate in a certain spatial position while ensuring that the fixed position will not change, thereby improving the applicability of the device. Specifically, the elastic member 320 is carbon spring steel or silicon manganese spring steel; the material of the guide sleeve base 310 is stainless steel or carbon steel, and the guide sleeve base 310 is spot welded to the upper middle part of the bottom plate 130 by argon arc welding.

[0042] Furthermore, the second pulley 340 is a nylon track pulley, which can be replaced according to the wire diameters of different cables. A slide groove is provided in the middle of the second pulley 340. The shape of the slide groove can be U-shaped or V-shaped, and can also be expanded according to the number of cables. The use of the slide groove facilitates the cable to slide to a certain extent.

By providing the gasket 350, the friction between the arc-shaped outer wall of the sliding portion 331 and the arc-shaped inner wall of the guide sleeve base 310 is increased, and the activity performance of the elastic member 320 is improved.

[0044] In an optional embodiment, if Figure 3 As shown, a limiting portion 332 is provided in the mounting groove 331A, and one end of the elastic member 320 connected to the guide sleeve head 330 is connected to the limiting portion 332. Specifically, the limiting portion 332 is a circular ring provided at the top of the mounting groove 331A. By providing the limiting portion 332, the end of the elastic member 320 is clamped in the annular groove of the limiting portion 332, thereby preventing the elastic member 320 from deviating during the movement, thereby improving the stability of the device.

Similarly, the lower pulley mechanism 300 further includes a second bearing, and the second pulley 340 and the guide sleeve head 330 are connected via the second bearing. In order to make the first pulley 220 and the second pulley 340 more stable during use, the first pulley 220 is connected to the adjusting rod 210 via the first bearing, so that the first pulley 220 and the second pulley 340 rotate more smoothly during the installation of the cable lead, with good stability, and support a certain degree of sliding of the cable in a fixed direction, which is convenient for the staff to operate.

[0046] The cable fixing device described in the embodiment of the present application, and its operation method comprises the following steps:

[0047] Pass the cable through between the upper pulley mechanism 200 and the lower pulley mechanism 300; fix the cable fixing device to the surface to be fixed by the first fastener; adjust the position of the adjustment rod 210 until the elastic member 320 in the lower pulley mechanism 300 is miniaturized; adjust the adaptability angle of the cable; lock the position of the adjustment rod 210 by the second fastener and the third fastener.
