Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model relates to a modular quick-connection assembly for nuclear power cable trays, comprising two symmetrically arranged cable tray bodies 1, with fixing posts 2 symmetrically fixed on the outer sides of the two cable tray bodies 1 at their adjacent ends, and an adjustment connection mechanism 3 provided between the two cable tray bodies 1. In use, the interaction of the cable tray bodies 1, fixing posts 2, and adjustment connection mechanism 3 enables the nuclear power cable trays to be quickly connected during use, improving work efficiency and thus achieving better practicality.

[0020] The adjusting connection mechanism 3 includes symmetrically arranged movable seats 4. Through holes 5 are evenly distributed throughout the interior of each movable seat 4. Four fixing sleeves 6 are symmetrically fixedly installed on the opposite sides of each movable seat 4, and the fixing sleeves 6 are fixedly installed on one side of the through holes 5 and on the outside of the fixing posts 2. A strip frame 7 is provided between the two movable seats 4, and both ends of the strip frame 7 are open structures. The strip frame 7 is located between the bottom ends of the two cable tray bodies 1 that are close to each other. An adjusting shaft 8 is rotatably installed in the center of the strip frame 7, and the bottom of the adjusting shaft 8 extends to the bottom of the strip frame 7. An adjusting block 9 is fixedly installed at the bottom of the adjusting shaft 8. An adjusting gear 10 is fixedly installed inside the strip frame 7 and on the outside of the adjusting shaft 8. A movable rack 11 is interlocked and connected to the outer side of the adjusting gear 10. A movable block 12 is fixedly installed at the end of the movable rack 11 near the adjusting gear 10. A movable rod 13 is fixedly installed on the side of the movable block 12 away from the adjusting gear 10. The end of the movable rod 13 away from the movable block 12 is fixedly connected to the movable seat 4. A movable ring 14 is fixedly installed on the outer side of the end of the movable rod 13 near the movable block 12. A positioning spring 15 is fixedly installed on the side of the movable ring 14 away from the movable block 12. The positioning spring 15 is sleeved on the outer side of the movable rod 13. A positioning ring 16 is fixedly installed at the end of the positioning spring 15 away from the movable ring 14. The positioning ring 16 is fixedly installed inside the strip frame 7. The movable rod 13 is movably installed through the inside of the positioning ring 16.

[0021] A positioning sleeve 17 is fixedly installed on the side of the movable rack 11 away from the adjusting gear 10. A positioning slide rod 18 is slidably installed inside the positioning sleeve 17. Connecting blocks 19 are fixedly installed at both ends of the positioning slide rod 18, and the connecting blocks 19 are fixedly installed inside the strip frame 7. Positioning slide strips 20 are symmetrically fixedly installed on the inner wall of the positioning sleeve 17. Positioning slide grooves 21 are symmetrically opened on the outer side of the positioning slide rod 18, and the positioning slide strips 20 are slidably installed inside the positioning slide grooves 21. In use, through the interaction of the positioning sleeve 17, positioning slide rod 18, connecting block 19, positioning slide strip 20 and positioning slide groove 21, the movable rack 11 can achieve better stability when moving, thereby ensuring that the adjusting connection mechanism 3 can work stably.

[0022] Working Principle: During operation, the two cable tray bodies 1 are first aligned and brought into contact with each other on their closest sides. Then, the adjusting block 9 is rotated, causing the adjusting shaft 8 to rotate. The adjusting shaft 8 then rotates the adjusting gear 10, which in turn drives the two movable racks 11 to move in opposite directions simultaneously. The movable racks 11 drive the positioning sleeve 17 to slide outside the positioning slide rod 18, and the positioning sleeve 17 drives the positioning slide bar 20 to slide inside the positioning groove 21. This ensures better stability of the movable racks 11 during movement. Simultaneously, the movable racks 11 drive the movable block 12 to move, which in turn drives the movable rod 13 to move inside the positioning ring 16. The movable rod 13 then drives the movable ring 14 to move, which in turn compresses the positioning spring 15. At the same time, the movable rod 13 drives the movable seat 4 to move, causing the two movable seats 4 to move away from each other. After the distance between the two movable seats 4 is greater than the distance between the fixed columns 2 on both sides of the end of the cable tray body 1, stop rotating the adjusting block 9. Then, place the adjusting connecting mechanism 3 between the two cable tray bodies 1, so that the top of the strip frame 7 contacts the bottom of the cable tray body 1, and at the same time align the through hole 5 on the movable seat 4 with the fixed column 2. Then, press the strip frame 7 and release the adjusting block 9. At this time, under the rebound force of the positioning spring 15, push the movable ring 14 to reset. The movable ring 14 drives the movable rod 13 to reset, and the movable rod 13 drives the movable seat 4 to reset. The movable seat 4 drives the fixed sleeve 6 to be sleeved on the outside of the fixed column 2, and fix the connection between the two cable tray bodies 1. This allows the nuclear power cable tray to be quickly connected during use, improving work efficiency and thus facilitating better practicality.
