[0027] See attached Figure 1-4As shown, the utility model embodiment of a stainless steel cable bridge includes a wire trough 100, and the inner walls of both sides of the wire trough 100 are provided with square holes 103, and the inner cavity of the square hole 103 is slidably connected to a first wedge block 302, and the surface of the first wedge block 302 is slidably connected to a second wedge block 307, and the surface of the second wedge block 307 is slidably connected to the inner wall of the square hole 103, and the top surface of the first wedge block 302 is rotatably connected to a threaded rod 300, and one end of the threaded rod 300 is connected to the inner wall of the square hole 103. The first wedge block 302 is provided with a strip hole 304 on its surface, which penetrates upward through the surface of the wire trough 100 and extends to the outside of the wire trough 100. A tension spring 303 is fixedly connected to the facing surfaces of the two sets of second wedge blocks 307. The other end of the tension spring 303 penetrates through the strip hole 304 and is fixedly connected to the inner wall of the square hole 103.

[0038] When the laying of the power busbar is completed, the cover plate 102 is taken out, and the connecting column 202 on the surface of the cover plate 102 is aligned with the snap-in hole 108 and inserted into the inner cavity of the snap-in hole 108, and then the connecting block 200 is rotated so that the snap-in block 201 is snap-fitted into the inner cavity of the snap-in hole 108, thereby connecting the cover plate 102 and the cable trough 100 together.
[0039] In summary, the embodiment of the utility model places the power busbar in the cable duct 100 by setting the second wedge block 307, and at the same time rotates the threaded rod 300 so that one end of the threaded rod 300 moves downward, thereby pushing the first wedge block 302 downward, and at the same time, while the first wedge block 302 moves downward, the second wedge block 307 is moved to one side of the power busbar, so that the rubber sheet 308 on the surface of the second wedge block 307 contacts the surface of the power busbar, thereby fixing the power busbar, so that it is not restricted by the external space, and the threaded rod 300 can be rotated according to the width of the power busbar, so as to control the moving distance of the second wedge block 307, thereby adapting to various types of power buses, thereby improving the applicability of the cable duct 100.
