[0026] The following further describes the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0027] Refer to Figures 1 to 6As shown in the figure, a cable fixing device for line maintenance of the present utility model includes a rectangular plate 1. One end of the rectangular plate 1 is provided with a rectangular through groove 2. The rectangular plate 1 is provided with a circular through groove 3 at a position adjacent to the rectangular through groove 2. The rectangular plate 1 is provided with a through hole 4 between the rectangular through groove 2 and the circular through groove 3. The rectangular through groove 2 communicates with the circular through groove 3 through the through hole 4. A support clamping plate 5 is arranged at one end of the circular through groove 3 away from the through hole 4. An elastic clamping plate 6 is arranged at one end of the circular through groove 3 where the through hole 4 is located. A wire nut 7 is rotatably connected at a position adjacent to the through hole 4 inside the rectangular through groove 2. A lead screw 8 is threadedly connected to the inner wall of the wire nut 7. One end of the lead screw 8 is fixedly connected to the elastic clamping plate 6. First sliding grooves 9 are respectively arranged at both ends of the circular through groove 3. A rectangular groove 10 is arranged on the side wall at one end of the bottom of the first sliding groove 9. First sliding blocks 11 are respectively fixedly connected to both ends of the outer wall of the support clamping plate 5. The first sliding blocks 11 are slidably connected to the first sliding grooves 9, and the first sliding blocks 11 are clamped with the rectangular grooves 10. One end of the side wall of the through hole 4 is provided with a second sliding groove 21. A second sliding block 22 is fixedly connected to one end of the lead screw 8. The second sliding groove 21 is slidably connected to the second sliding block 22. Handles 23 are respectively fixedly connected to both ends of the outer wall of the wire nut 7. An opening 24 is arranged at one end of the rectangular plate 1 away from the rectangular through groove 2. One end of the opening 24 communicates with the circular through groove 3.

[0028] In this embodiment, first, the rectangular plate 1 is installed at an appropriate position to facilitate subsequent operations. Then, the support clamping plate 5 is pushed towards the elastic clamping plate 6, so that the first sliding block 11 moves out of the rectangular groove 10 and enters the first sliding groove 9. At this time, the support clamping plate 5 is moved along the top direction of the first sliding groove 9, and the support clamping plate 5 can be disassembled. Then, the cable is placed into the circular through groove 3 through the opening 24 below the rectangular plate 1. Then, the support clamping plate 5 is slid into the first sliding groove 9 until the support clamping plate 5 completely enters the circular through groove 3 and the first sliding block 11 is exactly clamped into the rectangular groove 10. At this time, the support clamping plate 5 will no longer slide. Then, it is necessary to adjust the gap between the support clamping plate 5 and the elastic clamping plate 6 according to the number of cable bundles. At this time, the wire nut 7 is rotated by rotating the handle 23, so as to drive the lead screw 8 to move. The second sliding groove 21 on the lead screw 8 is slidably connected with the second sliding groove 21 in the through hole 4, which plays a limiting role, so that the lead screw 8 will not rotate with the rotation of the wire nut 7 and can only move along the axis direction of the lead screw 8, thereby driving the elastic clamping plate 6 to move, so as to adjust the gap between the elastic clamping plate 6 and the support clamping plate 5, and further facilitate the clamping and fixing of cables with different numbers or specifications.

[0029] Further, as Figures 1 to 3 shown, a T-shaped block 12 is fixedly connected to one end of the side wall of the rectangular plate 1, and a T-shaped groove 13 adapted to the T-shaped block 12 is arranged on the side wall of the other end of the rectangular plate 1;

[0030] In this embodiment, through the design of the T-shaped block 12 and the T-shaped groove 13, the fixing device can select the number of rectangular plates 1 according to the actual situation to adapt to the fixing of different numbers of cables, increasing the applicability and flexibility of the fixing device. Moreover, the splicing is achieved through the design of the T-shaped block 12 and the T-shaped groove 13, making the splicing process very convenient, thereby reducing the time for the staff to splice the fixing device.

[0031] Further, as Figures 1 to 3 shown, two first threaded grooves 14 are respectively provided on the side walls at both ends of the T-shaped block 12, and two second threaded grooves 15 are respectively provided at both ends of the rectangular plate 1 located in the T-shaped groove 13. The first threaded groove 14 and the second threaded groove 15 are both in the shape of a semi-cylindrical shape that matches each other;

[0032] In this embodiment, through the design of the first threaded groove 14 and the second threaded groove 15, it is convenient to fix the two rectangular plates 1 spliced together. During operation, when the T-shaped block 12 on one rectangular plate 1 is spliced into the T-shaped groove 13 of another rectangular block, at this time, the first threaded groove 14 and the second threaded groove 15 will be spliced into a complete threaded columnar structure, and then the two rectangular plates 1 can be fixed together by bolts.

[0033] Further, as Figures 1 to 3 shown, two elastic bumps 16 are fixedly connected to one end of the side wall of the T-shaped block 12. The elastic bumps 16 are in the shape of a semi-spherical ball, and two hemispherical grooves 17 that match the elastic bumps 16 are provided on one end of the side wall of the T-shaped groove 13;

[0034] In this embodiment, through the design of the elastic bumps 16 and the semi-spherical grooves, when the two rectangular plates 1 are spliced together, they can be more stable. During operation, one end of the T-shaped block 12 on one rectangular plate 1 is inserted into the T-shaped groove 13 on another rectangular plate 1 and slid inward. When the elastic bumps 16 on the T-shaped block 12 are embedded in the semi-circular grooves on the T-shaped groove 13, at this time, the two ends of the two rectangular blocks will be flush and will not slide, thus facilitating the subsequent staff to fix the two rectangular plates 1 together by bolts.

[0035] Further, as Figure 1 and Figure 5 shown, four fixing columns 18 are fixedly connected around the through hole 4 inside the rectangular through groove 2. One end of the four fixing columns 18 is commonly fixedly connected to a mounting plate 19. The nut 7 is located in the middle of the mounting plate 19, and the nut 7 is connected to the mounting plate 19 through a bearing 20;

[0036] In this embodiment, through the design of the fixing columns 18, the mounting plate 19 and the bearing 20, the nut 7 can be smoothly rotatably connected inside the rectangular through groove 2.

[0037] Working principle: First, the rectangular plate 1 is installed in a proper position to facilitate subsequent operations. Then, the supporting clamping plate 5 is pushed towards one end of the elastic clamping plate 6, so that the first slider 11 moves out of the rectangular groove 10 and into the first sliding groove 9. At this time, moving the supporting clamping plate 5 along the top direction of the first sliding groove 9 can disassemble the supporting clamping plate 5. Then, the cable is placed into the circular through groove 3 at the opening 24 below the rectangular plate 1, and then the supporting clamping plate 5 is slid into the first sliding groove 9 until the supporting clamping plate 5 completely enters the circular through groove 3 and the first slider 11 just snaps into the rectangular groove 10. At this time, the supporting clamping plate 5 will no longer slide. Then, it is necessary to adjust the gap between the supporting clamping plate 5 and the elastic clamping plate 6 according to the number of cable bundles. At this time, turning the handle 23 drives the nut 7 to rotate, thereby driving the screw rod 8 to move. The second sliding groove 21 on the screw rod 8 is slidably connected with the second sliding groove 21 in the through hole 4, which plays a limiting role, so that the screw rod 8 will not rotate with the rotation of the nut 7 and can only move along the axis direction of the screw rod 8, thereby driving the elastic clamping plate 6 to move, so as to adjust the gap between the elastic clamping plate 6 and the supporting clamping plate 5, and further facilitate the clamping and fixing of cables with different numbers or specifications. When it is necessary to splice multiple rectangular plates 1 together, one end of the T-shaped block 12 on one rectangular plate 1 is inserted into the T-shaped groove 13 on another rectangular plate 1 and slid inward. When the elastic convex block 16 on the T-shaped block 12 is embedded into the semi-circular groove on the T-shaped groove 13, the two ends of the two rectangular blocks will be flush and will not slide. At this time, the first thread groove 14 and the second thread groove 15 will be spliced into a complete threaded columnar structure, and then the two rectangular plates 1 can be fixed together by bolts.

[0038] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
