[0026] Refer to Figures 1 to 7, in an embodiment of the utility model, a fire-fighting electrical pipeline bridge includes a bridge body 1. On the upper surface of the side wall of the bridge body 1, there is a mating groove 102. On the side surface of the bridge body 1, there is a first mating hole 101. The first mating hole 101 and the mating groove 102 are in through communication. On the upper surface of the side wall of the bridge body 1, there is a cover plate 2. On the lower surface of the cover plate 2, a mating block 3 is fixedly connected. The mating block 3 is fitted in the mating groove 102. On the side surface of the mating block 3, there is a second mating hole 301. The diameter of the second mating hole 301 is the same as the diameter of the first mating hole 101. The axis line of the first mating hole 101 coincides with the axis line of the second mating hole 301. On the lower surface of the interior of the bridge body 1, there is a card slot mechanism 5. The number of the card slot mechanisms 5 is multiple. On the side surface of the bridge body 1, there is a locking mechanism 4.

[0027] The card slot mechanism 5 includes a bottom plate 501, a moving block 502, a scale plate 503 and a tightening screw 504. The bottom plate 501 is fixedly connected to the lower surface of the interior of the bridge body 1. On the upper surface of the bottom plate 501, there is a T-shaped groove. The moving block 502 is slidably connected in the T-shaped groove of the bottom plate 501. On the side surface of the moving block 502, there is a side plate that is stuck at the bottom of the T-shaped groove. The scale plate 503 is fixedly connected to the upper surface of the bottom plate 501.

[0028] The number of the moving blocks 502 is two. On the upper surface of the moving block 502, there is a through-threaded hole. The tightening screw 504 is threadedly connected in the threaded hole of the moving block 502. The distance between the two moving blocks 502 is adjustable, so as to be applicable to cables of different specifications. When the bottom end of the rod part of the tightening screw 504 is in close contact with the lower surface of the T-shaped groove of the bottom plate 501, the side plate of the moving block 502 will be pressed against the upper surface at the bottom end of the T-shaped groove, and the position of the moving block 502 is fixed by the frictional force between the two.

[0029] The locking mechanism 4 includes a support rod 401, a pull block 402, a spring 403, a sliding shaft 404, a fixed shaft 405 and a baffle 406. The support rod 401 is fixedly connected to the side surface of the bridge body 1. The support rod 401 is L-shaped. On the side surface of the vertical part of the support rod 401, there is a through-round hole. The fixed shaft 405 is fixedly connected to the side surface of the bridge body 1. The baffle 406 is rotatably connected to the cylindrical surface of the fixed shaft 405.

[0030] The sliding shaft 404 is slidably connected to the cylindrical surface of the through-round hole of the support rod 401. The sliding shaft 404 passes through the first mating hole 101 and the second mating hole 301. The pull block 402 is fixedly connected to the end face of the sliding shaft 404 away from the bridge body 1. The spring 403 is fixedly connected between the pull block 402 and the support rod 401. The spring 403 is looped around the cylindrical surface of the sliding shaft 404. The spring 403 is always in a tensioned state.

[0031] Working principle: Before installation, pull the pulling block 402 to pull out the sliding shaft 404 from the first mating hole 101, and rotate the baffle 406 to block the first mating hole 101. Then release the pulling block 402, and the spring 403 will use its own pulling force to push the sliding shaft 404 to the position where it contacts the baffle 406. Then install the cover plate 2 on the bridge main body 1. At this time, the mating block 3 is fitted in the mating groove 102. Then rotate the baffle 406 to make the baffle 406 disengage from the first mating hole 101. At this time, the spring 403 will pull the sliding shaft 404 into the first mating hole 101 and the second mating hole 301, thereby fixing the position of the cover plate 2. When disassembling, after pulling out the sliding shaft 404 from the second mating hole 301, the cover plate 2 can be removed. The process of installing and disassembling the cover plate 2 is simple and fast, and no professional tools are required.
