[0004] However, regardless of whether it is connected by bolts or fixed by welding, tools are required when installing the cable tray, and the operation method is relatively cumbersome. Even in the subsequent dismantling work, it will be greatly affected. In addition, the cable tray is generally closed after installation, resulting in poor air flow inside and outside, which is not conducive to heat dissipation inside the cable tray. Utility Model Content

[0028] Specifically, select a bridge frame body 1, and install its right end at the outlet according to the orientation in the figure. There are mounting plates on both the upper and lower ends and the left and right sides of the bridge frame body 1, and mounting holes are provided in the mounting plates. The first bridge frame body 1 installed at the outlet needs to be screwed through the mounting holes and firmly fixed at the outlet. Then, the remaining bridge frame bodies 1 are installed on the left side of the fixed bridge frame body 1 in turn, and the damping shaft 15 on the left side of the fixed bridge frame body 1 is rotated to make the blocking block 16 face vertically upward. Then, the right sleeve 4 of the other bridge frame body 1 is aligned with the sliding bolt 6, so that the blocking block 16 passes through the through slot 14 and the hole slot 13 is sleeved on the outer wall of the sliding bolt 6. Then, the damping shaft 15 is rotated to reset, so that the blocking block 16 faces vertically downward again, thereby producing a limiting effect on the sleeve 4, thereby achieving stable installation of the bridge frame body 1, and subsequent installation can be carried out in sequence according to the above method;

[0029] To further explain, when the entire bridge needs to be dismantled, it is first necessary to rotate the damping shaft 15 on one side of the bridge body 1 so that the blocking block 16 is vertically upward, and then slide the slide bolt 6 so that its outer wall is separated from the sleeve 4 on the corresponding side, thereby releasing the limit on the bridge body 1.
