[0013] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, a low-voltage cable fixing structure for an underground transformer includes a cable fixing plate 1, wherein sliding holes 2 are sequentially opened on the inner upper side of the cable fixing plate 1 from left to right, and through holes 3 are respectively opened in the middle part of the inner bottom of the sliding holes 2; superior arc-shaped plug holes 4 are sequentially opened on the inner upper side of the cable fixing plate 1 from left to right, and one of the sliding holes 2 is arranged on the right side of each of the superior arc-shaped plug holes 4.

[0014] One of the underground transformer low-voltage cable fixing structures also includes a monotonic fastening component 5, and the monotonic fastening components 5 are respectively inserted into the interior of the arc-shaped socket 4; the monotonic fastening components 5 are also respectively rotatably installed in the through holes 3, wherein the monotonic fastening components 5 are also respectively slidably arranged in the interior of the sliding hole 2, which is conducive to achieving the effect of clamping and fixing cables of different diameters, and is more convenient to use.

[0015] In this embodiment, combined with the Figure 3 As shown, the monotonic fastening assembly 5 comprises a fastening belt 51, one end of which is integrally connected with an insert rod 52, and the other end is integrally connected with a slider 53, and a threaded through hole is longitudinally opened in the middle part of the inner part of the slider 53, wherein the threaded through hole is located on the right side of the fastening belt 51; a threaded rod 54 is connected to the inner thread of the threaded through hole, and a hexagonal block 55 is fixedly connected to the lower end of the threaded rod 54, wherein an annular stopper 56 is fixedly connected to the lower side of the outer wall of the threaded rod 54; the annular stopper 56 is located on the lower side of the slider 53.

[0016] In this embodiment, specifically, the insertion rods 52 are respectively inserted into the interior of the superior arc-shaped insertion holes 4 .

[0017] In this embodiment, specifically, the sliding blocks 53 are slidably disposed inside the sliding holes 2 .

[0018] In this embodiment, specifically, the threaded rods 54 are rotatably arranged inside the through holes 3, and the hexagonal blocks 55 at the lower ends of the threaded rods 54 are located at the lower part of the cable fixing plate 1; the annular stoppers 56 on the lower side of the outer wall of the threaded rods 54 are located at the inner bottom of the sliding holes 2.

[0019] In this embodiment, specifically, the sliding hole 2 is a hole with a rectangular cross section; the sliding block 53 is a rectangular block adapted to the interior of the sliding hole 2 .

[0020] In this embodiment, specifically, the fastening belt 51 is made of a stainless steel soft belt.

[0021] In this embodiment, specifically, the insertion rod 52 is a cylindrical stainless steel rod adapted to the interior of the arc-shaped insertion hole 4 .

[0022] In this embodiment, when fixing the low-voltage cable, the operator can first push the plug rod 52 through the tightening belt 51 to move the plug rod 52 out of the interior of the superior arc-shaped socket 4, and then the operator can place the low-voltage cable on the upper side of the cable fixing plate 1, and then the tightening belt 51 crosses the low-voltage cable and inserts the plug rod 52 into the interior of the superior arc-shaped socket 4. At this time, the low-voltage cable is located between the tightening belt 51 and the cable fixing plate 1. Then the operator can use an external wrench to rotate the hexagonal block 55 so that the hexagonal block 55 drives the slider 53 from the slide hole 2 through the threaded rod 54. The interior slides downward, and the tightening belt 51 will gradually approach the low-voltage cable and press the low-voltage cable on the upper side of the cable fixing plate 1, thereby completing the fixation of the low-voltage cable. Because the slider 53 can drive one end of the tightening belt 51 to move up and down, the size of the space between the lower surface of the tightening belt 51 and the cable fixing plate 1 will change. Since the space between the lower surface of the tightening belt 51 and the cable fixing plate 1 has a large range of variation, the present fixing structure can fix low-voltage cables of various diameters, thereby achieving the effect of facilitating the clamping and fixing of cables of different diameters, and is more convenient to use.
