Figure 8 For the present invention Figure 7 In the enlarged structural diagram at point B, a first docking bar 7 is fixedly connected to one side of the first connecting block 5, and an arranged connecting groove 71 is provided on one side of the first docking bar 7. A second docking bar 8 is fixedly connected to one side of the second connecting block 6. The first docking bar 7 and the second docking bar 8 are slidingly plugged into each other. By adjusting the relative distance between the first docking bar 7 and the second docking bar 8, the relative distance between the first connecting frame 3 and the second connecting frame 4 is adjusted.

[0045] A linearly distributed connector fixing mechanism is provided on one side of the second docking strip 8. The connector fixing mechanism includes an elastic damping component and a buffer friction component. The elastic damping component includes a limit seat 81 and a through block 85. The limit seat 81 is fixedly connected to one side of the second docking strip 8. A receiving groove is provided on the limit seat 81. A mounting block 82 is provided at the opening of the receiving groove. The mounting block 82 is fixed to the limit seat 81 by bolts.

[0046] A pull column 83 is slidably inserted into the mounting block 82, a connecting strip 831 is fixedly connected between the two pull columns 83, a support spring 832 is sleeved on the pull column 83, a fixed block 84 is fixedly connected to the pull column 83, and a through block 85 is fixedly connected to the end of the fixed block 84, and the end of the through block 85 passes through the connecting groove 71.

[0047] The buffer friction assembly includes a rotating block 87, and grooves 86 are provided on both sides of the penetration block 85. A fixed shaft 88 is provided on the groove 86. The rotating block 87 is rotatably sleeved on the fixed shaft 88, and a torsion spring 89 is sleeved on the fixed shaft 88. One end of the torsion spring 89 is fixedly connected to the fixed shaft 88, and the other end is fixedly connected to the rotating block 87. The rotating block 87 in the buffer friction assembly is tightly attached to the side wall of the connecting groove 71 under the action of the torsion spring 89, and the vibration is further suppressed through friction damping to prevent the plug-in structure from disengaging under high-frequency vibration.

[0048] The connection between the connecting groove 71 and the through block 85 forms a lock between the first docking bar 7 and the second docking bar 8, so that the first connecting frame 3 and the second connecting frame 4 are fixed. The elastic damping component absorbs vibration energy through the support spring 832 to avoid rigid transmission.

[0049] Figure 9 This is a schematic diagram of the structure of the components installed between the cable tray body and the upper cover plate of the present invention. Figure 10 For the present invention Figure 9 In the enlarged structural diagram at point C, installation components between the cable tray body and the upper cover are provided on both sides of the first connecting frame 3 and the second connecting frame 4. The installation components include a cylinder 10. The cylinders 10 on the first connecting frame 3 and the second connecting frame 4 are respectively fixedly connected to one side of the first connecting frame 3 and the second connecting frame 4. A circular cover 104 is provided at the opening of the cylinder 10, and the circular cover 104 is fixed to the cylinder 10 by bolts.

[0050] A moving rod 101 is slidably inserted into the circular cover plate 104, and a connecting rod 102 is provided between one end of the moving rod 101 and the corresponding pulling rod 53 on its lower side. An elastic member 105 is sleeved on the moving rod 101, and a cover plate fixing member 103 is provided at the end of the moving rod 101. The ends of the cover plate fixing member 103 on the first connecting frame 3 and the second connecting frame 4 pass through the first limiting groove 13 and the second limiting groove 23 and are inserted into the avoidance groove 25.

[0051] The cover plate fixing part 103 is driven by the moving rod 101 to be inserted into the avoidance groove 25 of the bridge frame body to fix the upper cover plate to the bridge frame body to prevent the cover plate from sliding. The elastic part 105 provides a pre-tightening force to ensure that the cover plate fixing part 103 is tightly fitted with the avoidance groove 25, while allowing the cover plate to move slightly when subjected to external force to avoid jamming.

[0052] The second cable tray body 2 is rotatably connected to a rotating column 9, and telescopic blocks 91 are provided on both sides of the rotating column 9. The ends of the telescopic blocks 91 pass through the fixed slot seat 51. When disassembly is required, the pulling rod 53 is pulled outward to move the ring block 54, and then the end of the telescopic block 91 is extended into the fixed slot seat 51, and the pulling rod 53 is released. Under the elastic force of the abutting spring 55, the ring block 54 overlaps the end of the telescopic block 91. At this time, the end of the plug block 56 is away from the through slot, which is convenient for disassembly on both sides of the cable tray body and can be operated with one hand.

[0053] During actual installation, align the upper and lower sides of the first connecting frame 3 with the upper and lower sides of the end of the first cable tray body 1, and slide and insert along the direction of the first slide groove 14; align the upper and lower sides of the second connecting frame 4 with the upper and lower sides of the end of the second cable tray body 2, and slide and insert along the direction of the second slide groove 24. According to actual needs, adjust the distance between the first cable tray body 1 and the second cable tray body 2 by sliding the first connecting frame 3 and the second connecting frame 4.

[0054] The insertion block 56 on the first connecting block 5 and the second connecting block 6 is aligned with the first through slot 12 and the second through slot 22, and the pulling rod 53 is released. Under the action of the abutting spring 55, the insertion block 56 is automatically inserted into the through slot to lock the spacing of the bridge body; the first docking bar 7 and the second docking bar 8 are brought close and slid together to ensure that the through block 85 enters the connecting slot 71. The connection between the connecting slot 71 and the through block 85 forms a lock between the first docking bar 7 and the second docking bar 8, so that the first connecting frame 3 and the second connecting frame 4 are fixed, and the first upper cover plate 11 and the second upper cover plate 21 are respectively slid to the top of the first cable bridge body 1 and the second cable bridge body 2, so that the bent parts on both sides are fitted on the side of the bridge body; pull the moving rod 101 to insert the cover plate fixing piece 103 into the avoidance groove 25 to fix the upper cover plate on the bridge body.

[0055] When the cover plates are removed, the movable rod 101 is pulled to overcome the pre-tightening force of the elastic member 105 and the cover plate fixing member 103 is pulled out from the avoidance groove 25 , and the first upper cover plate 11 and the second upper cover plate 21 can be removed.

[0056] When disassembling the bridge body, rotate the rotating column 9 to extend the end of the telescopic block 91 into the fixed slot seat 51, lift the pulling rod 53, so that the end of the insertion block 56 is away from the through slot, pull the pulling rod 53, overcome the elastic force of the abutment spring 55, pull the insertion block 56 out of the through slot, and release the lock between the bridge bodies; pull the pulling column 83 to overcome the elastic force of the supporting spring 832, pull the through block 85 out of the connecting groove 71, and release the lock of the docking strip; pull the first connecting frame 3 out of the first slide groove 14, and pull the second connecting frame 4 out of the second slide groove 24. The first cable bridge body 1 and the second cable bridge body 2 have been completely separated and can be transported or installed separately.

[0057] The support spring 832 can absorb vibration energy, avoid rigid transmission, protect the bridge structure, and the rotating block 87 in the buffer friction assembly is tightly attached to the side wall of the connecting groove 71 under the action of the torsion spring 89, and the vibration is further suppressed through friction damping to prevent the plug-in structure from disengaging under high-frequency vibration; overall, through the design of the connecting frame, connecting block, sliding fixing assembly, and elastic damping assembly, the rigidity and load-bearing capacity of the bridge are enhanced as a whole, so that it can withstand greater cable weight and external loads, and effectively resist deformation in high-vibration environments.

[0058] Sliding slots enable the first connecting frame 3 to slide into the first cable tray body 1, and the second connecting frame 4 to slide into the second cable tray body 2, enhancing the contact area and stability of the connections. The first connecting block 5 and the second connecting block 6 securely connect the upper and lower connecting frames, further enhancing the rigidity and torsional resistance of the connection. The insert block 56, under the action of the abutment spring 55, automatically inserts into the first and second through slots 12 and 22 of the cable tray body, achieving boltless fixation and ensuring reliable connection. The insertion of the connecting slot 71 and the through block 85 locks the first and second docking bars 7 and 8, securing the first connecting frame 3 and the second connecting frame 4.
