[0024] Example

[0025] This utility model provides a combined ladder-type cable tray, see reference. Figure 1-4 As shown, the cable tray includes a main body, which includes two side baffles 1. Multiple detachably connected crossbeams 3 are provided between the two side baffles 1. T-shaped fastening blocks 5 are symmetrically provided on both sides of the bottom end face of the crossbeams 3. A bearing plate 2 perpendicular to the side baffle 1 is provided at the bottom of the side baffle 1. The bearing plate 2 and the side baffle 1 are integrally formed.

[0026] refer to Figure 3 As shown, the top end face of the support plate 2 is provided with a plurality of guide grooves 6 for fastening blocks 5 to be inserted. On one side of the top end face of the support plate 2, a fastening groove 7 is provided for fastening blocks 5 to be inserted into the guide groove 6 and then displaced and locked. The fastening groove 7 fits with the fastening block 5 and is connected to the guide groove 6. On the other side of the top end face of the support plate 2, a locking groove 8 is provided. The locking groove 8 is connected to the guide groove 6. A locking block 4 that can block the guide groove 6 is slidably provided in the locking groove 8. By setting the locking block 4, the fastening block 5 can be prevented from sliding out of the fastening groove 7. One side of the locking block 4 is provided with a guide block 10 with a trapezoidal structure, and the other side of the locking block 4 is provided with a connecting plate 13 extending to the outside of the support plate 2.

[0027] The locking groove 8 has a guide groove 9 on one inner side wall for the guide block 10 to move. The guide groove 9 and the guide block 10 are designed to prevent the locking block 4 from shifting during displacement. The locking groove 8 also has a connecting groove 11 on the other inner side wall for the connecting plate 13 to move.

[0028] Furthermore, a drive plate 12 is provided on the bearing plate 2 on one side of the connecting groove 11. A drive threaded hole is provided through the drive plate 12. A drive threaded rod 14, one end of which is rotatably connected to the connecting plate 13, is screwed into the drive threaded hole. The drive threaded rod 14 facilitates the operation of the locking block 4 by the operator. A fixing plate 15 is provided on the bearing plate 2 on the other side of the connecting groove 11. A fixing groove 16 is provided through the fixing plate 15.

[0029] Furthermore, the connecting plate 13 is provided with a fixed threaded rod 17 that can be inserted into the fixed groove 16. A fixed nut located on the outside of the fixed plate 15 is screwed onto the fixed threaded rod 17. By the arrangement of the fixed threaded rod 17 and the fixed nut, the displacement of the locking block 4 can be limited and fixed.

[0030] The working principle of this utility model is as follows:

[0031] When assembling and installing the main body of the cable tray, first align the fastening block 5 on the crossarm 3 with the guide groove 6 on the bearing plate 2 and insert it. Then, move the crossarm 3 so that the fastening block 5 in the guide groove 6 is engaged in the fastening groove 7, thus initially fixing the crossarm 3 to the side baffle 1. Then, rotate the drive threaded rod 14 to drive the connecting plate 13 to move the locking block 4, so that one end of the locking block 4 moves into the guide groove 6 until it abuts against one side of the fastening block 5 in the fastening groove 7. At this time, the fixing threaded rod 17 on the connecting plate 13 is inserted into the fixing groove 16 on the fixing plate 15. Finally, screw the fixing nut onto the fixing threaded rod 17 inserted into the outside of the fixing plate 15 to fix and limit the displacement of the locking block 4. Install the remaining crossarm 3 between the two side baffles 1 in the above manner to fix it, thus completing the assembly and installation of the main body of the cable tray.

[0032] This utility model, through the modular structure of the cable tray, allows it to be disassembled during handling and transportation, reducing the floor space occupied during transportation and improving the space utilization rate. At the same time, it facilitates the assembly and installation of the ladder-type cable tray by the staff during use.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
