Both sides of the first upper cover plate 11 and the second upper cover plate 21 are bent and respectively fit on the sides of the first cable tray body 1 and the second cable tray body 2 to form a positioning slide, which is convenient for quickly opening and closing the cover plate for cable maintenance, and at the same time enhances the anti-deformation ability between the cover plate and the tray body.

[0033] Figure 2This is a schematic structural diagram between the cable tray body and the upper cover plate of the present invention. On both the upper and lower sides of the end of the first cable tray body 1, there are sliding connections with the first connecting frame 3. On both the upper and lower sides of the end of the second cable tray body 2, there are sliding connections with the second connecting frame 4. On both sides of the first cable tray body 1, there are first sliding grooves 14 opened. On both sides of the second cable tray body 2, there are second sliding grooves 24 opened. The first connecting frame 3 is slidably inserted into the first sliding groove 14, forming a slide between the first cable tray body 1 and the first connecting frame 3. The second connecting frame 4 is slidably inserted into the second sliding groove 24, forming a slide between the second connecting frame 4 and the second cable tray body 2.

[0034] The first connecting frame 3 and the second connecting frame 4 are slidably inserted into each other, which is convenient for telescopic movement. On the one hand, it strengthens the stiffness of the connection part. On the other hand, the distance between the first cable tray body 1 and the second cable tray body 2 can be adjusted according to actual needs. Compared with the traditional fixed installation of the cable tray body, it has stronger flexibility.

[0035] Figure 3 This is a schematic structural diagram of both sides of the cable tray body of the present invention. Figure 4 This is an exploded structural diagram of the cable tray body and the upper cover plate of the present invention. On both sides of the first cable tray body 1, there are first through grooves 12 opened. On both sides of the second cable tray body 2, there are second through grooves 22 opened. On the first upper cover plate 11, there is a first limiting groove 13 opened. On the second upper cover plate 21, there is a second limiting groove 23 opened. On both the first cable tray body 1 and the second cable tray body 2, there are avoidance grooves 25 arranged linearly.

[0036] Figure 5 This is a schematic structural diagram of the sliding fixing component of the present invention. Figure 6 This is for the present invention Figure 5 This is an enlarged structural diagram of part A in the present invention. There is a first connecting block 5 fixedly connected between the first connecting frames 3 on the upper and lower sides. There is a second connecting block 6 fixedly connected between the second connecting frames 4 on the upper and lower sides.

[0037] The sliding fixing component includes a fixed groove seat 51 and an insertion block 56. The fixed groove seat 51 is fixedly connected to the connecting block. At the opening of the fixed groove seat 51, there is a circular plate 52. The circular plate 52 is fixed to the fixed groove seat 51 by bolts. A pull rod 53 is slidably inserted into the circular plate 52, and a ring block 54 is fixedly connected to the pull rod 53.

[0038] A contact spring 55 is sleeved on the pull rod 53. The end of the pull rod 53 is fixedly connected with an insertion block 56. The ends of the insertion blocks 56 on the first connecting block 5 and the second connecting block 6 are respectively arranged corresponding to the first through groove 12 and the second through groove 22.

[0039] The insertion block 56 is automatically inserted into the first through groove 12 and the second through groove 22 of the bridge body under the action of the abutting spring 55, realizing boltless fixation, reducing the installation time. The design of the pull rod 53 and the ring block 54 allows manual pulling of the insertion block out of the through groove, facilitating quick disassembly and assembly. By pulling the pull rod 53, the elastic force of the abutting spring 55 can be overcome, and the insertion block 56 can be pulled out of the through groove to achieve quick disassembly and assembly. The cooperation between the insertion block 56 and the through groove, as well as the elastic force of the abutting spring 55, ensure the reliability of the connection.

[0040] Figure 7 It is a schematic structural diagram of the connecting piece fixing mechanism of the present invention. Figure 8 For the present invention Figure 7 It is a schematic enlarged structural diagram at B in the present invention. One side of the first connecting block 5 is fixedly connected with a first docking strip 7. A row of distributed connecting grooves 71 are opened on one side of the first docking strip 7. One side of the second connecting block 6 is fixedly connected with a second docking strip 8. The first docking strip 7 and the second docking strip 8 are slidably inserted and arranged between them. By adjusting the relative distance between the first docking strip 7 and the second docking strip 8, the relative distance between the first connecting frame 3 and the second connecting frame 4 is adjusted.

[0041] On one side of the second docking strip 8, there are linearly distributed connecting piece fixing mechanisms. The connecting piece 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 opened on the limit seat 81. An installation block 82 is arranged at the opening of the receiving groove. The installation block 82 is fixed to the limit seat 81 by bolts.

[0042] A pull column 83 is slidably inserted into the installation 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 fixing block 84 is fixedly connected to the pull column 83. The end of the fixing block 84 is fixedly connected with a through block 85. The end of the through block 85 penetrates through the connecting groove 71 and is arranged.

[0043] The buffer friction component includes a rotating block 87. Grooves 86 are opened on both sides of the through block 85. A fixed shaft 88 is arranged on the groove 86. A rotating block 87 is rotatably sleeved on the fixed shaft 88. 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 component 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 plugging structure from disengaging under high-frequency vibration.

[0044] The insertion of the connecting groove 71 and the through block 85 forms the locking between the first docking strip 7 and the second docking strip 8, making the first connecting frame 3 and the second connecting frame 4 fixed. The elastic damping component absorbs vibration energy through the support spring 832 to avoid rigid transmission.

[0045] Figure 9 This is a schematic structural diagram of the installation component 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 schematic diagram at position C, installation components are provided on both sides of the first connecting frame 3 and the second connecting frame 4. The installation component includes a cylinder 10. The two cylinders 10 are respectively fixedly connected to one side of the first connecting frame 3 and the second connecting frame 4. A circular cover plate 104 is provided at the opening of the cylinder 10, and the circular cover plate 104 is fixed to the cylinder 10 by bolts.

[0046] A moving rod 101 is slidably inserted into the circular cover plate 104. A connecting rod 102 is provided between one end of the moving rod 101 and the pulling rod 53. An elastic member 105 is sleeved on the moving rod 101. A cover plate fixing member 103 is provided at the end of the moving rod 101. The ends of the two cover plate fixing members 103 respectively penetrate through the first limiting groove 13 and the second limiting groove 23 and are inserted into the avoidance groove 25.

[0047] The cover plate fixing member 103 is driven by the moving rod 101 to be inserted into the avoidance groove 25 of the cable tray body, so as to fix the upper cover plate to the cable tray body and prevent the cover plate from sliding. The elastic member 105 provides a pre-tightening force to ensure the tight fit between the cover plate fixing member 103 and the avoidance groove 25, and at the same time allows the cover plate to have a small displacement when subjected to an external force, avoiding jamming.

[0048] A rotating column 9 is rotatably connected to the second cable tray body 2. Expansion blocks 91 are provided on both sides of the rotating column 9. The ends of the expansion blocks 91 penetrate through the fixed groove seat 51. When disassembly is required, the pulling rod 53 is pulled outwards to move the ring block 54, and then the end of the expansion block 91 is extended into the fixed groove seat 51. The pulling rod 53 is released, and under the elastic force of the abutting spring 55, the ring block 54 is lapped on the end of the expansion block 91. At this time, the end of the plug 56 is far away from the through groove, which is convenient for the disassembly of both sides of the cable tray body and can be operated with one hand.

[0049] During actual installation, the upper and lower sides of the first connecting frame 3 are respectively aligned with the upper and lower sides of the end of the first cable tray body 1, and are slidably inserted along the direction of the sliding groove 14; the upper and lower sides of the second connecting frame 4 are respectively aligned with the upper and lower sides of the end of the second cable tray body 2, and are slidably inserted along the direction of the sliding groove 24. According to actual needs, the distance between the first cable tray body 1 and the second cable tray body 2 is adjusted by sliding the first connecting frame 3 and the second connecting frame 4.

[0050] The insertion blocks 56 on the first connection block 5 and the second connection block 6 are aligned with the first through groove 12 and the second through groove 22. The pull rod 53 is released. Under the action of the abutting spring 55, the insertion blocks 56 automatically insert into the through grooves to lock the distance between the bridge body; the first docking strip 7 and the second docking strip 8 are brought close and slidably inserted, ensuring that the insertion block 85 enters the connection groove 71. The insertion of the connection groove 71 and the insertion block 85 forms a lock between the first docking strip 7 and the second docking strip 8, so that the first connection frame 3 and the second connection frame 4 are fixed. The first upper cover plate 11 and the second upper cover plate 21 are respectively slid to the tops of the first cable bridge body 1 and the second cable bridge body 2, and the bent parts on both sides thereof are attached to the sides of the bridge body; the moving rod 101 is pulled to make the cover fixing member 103 insert into the avoidance groove 25 to fix the upper cover plate on the bridge body.

[0051] When disassembling the cover plate, pull the moving rod 101 to overcome the pre-tightening force of the elastic member 105, and pull out the cover fixing member 103 from the avoidance groove 25, then the first upper cover plate 11 and the second upper cover plate 21 can be removed.

[0052] When disassembling the bridge body, rotate the rotating column 9 to extend the end of the telescopic block 91 into the fixed groove seat 51 to lift the pull rod 53, so that the end of the insertion block 56 is far away from the through groove. Pull the pull rod 53 to overcome the elastic force of the abutting spring 55 and pull out the insertion block 56 from the through groove to release the lock between the bridge bodies; pull the pull column 83 to overcome the elastic force of the support spring 832 and pull out the insertion block 85 from the connection groove 71 to release the lock of the docking strip; pull out the first connection frame 3 from the first sliding groove 14 and pull out the second connection frame 4 from the second sliding groove 24. The first cable bridge body 1 and the second cable bridge body 2 are completely separated and can be carried or installed separately.

[0053] The support spring 832 can absorb vibration energy to avoid rigid transmission, protect the bridge structure. The rotating block 87 in the friction damping assembly is tightly attached to the side wall of the connection groove 71 under the action of the torsion spring 89, and further suppresses vibration through friction damping to prevent the insertion structure from disengaging under high-frequency vibration; generally, through the design of the connection frame, connection block, sliding fixing assembly, and elastic damping assembly, the rigidity and bearing capacity of the bridge are enhanced as a whole, enabling it to bear greater cable weight and external loads and effectively resist deformation in a high-vibration environment.

[0054] The first connecting frame 3 and the first cable tray body 1, and the second connecting frame 4 and the second cable tray body 2 are slidably inserted through chutes, enhancing the contact area and stability at the connection. The first connecting block 5 and the second connecting block 6 fixedly connect the upper and lower connecting frames, further enhancing the stiffness and torsional resistance at the connection; the insertion block 56 is automatically inserted into the first through groove 12 and the second through groove 22 of the cable tray body under the action of the abutting spring 55, achieving bolt-free fixation and ensuring the reliability of the connection; the insertion of the connecting groove 71 and the through block 85 forms the locking between the first docking strip 7 and the second docking strip 8, fixing the first connecting frame 3 and the second connecting frame 4 together.
