[0037] The working principle of this utility model is as follows:

[0038] When two adjacent cable tray bodies are connected, the guide plate 4 on one cable tray body is first aligned with the guide groove 2 on the other cable tray body and inserted to initially fix the two adjacent cable tray bodies. Then, the drive handle 15 drives the mounting plate 13 to move the two locking rods 19. At the same time, the displacement of the mounting plate 13 causes the drive spring 18 to be compressed, causing the locking rods 19 to disengage from the first locking hole 11. At this time, the fastening plate 7 in the sliding displacement receiving groove 5 slides out of the receiving groove 5. When the fastening plate 7 is inserted into the fastening groove 8, and one end of the fastening plate 7 is inserted to the bottom of the fastening groove 8, the drive handle 15 is loosened. Under the action of the drive spring 18, the locking rod 19 is inserted into the second locking hole 9. At the same time, the first fixed threaded half-post 16 and the second fixed threaded half-post 10 on the mounting plate 13 are engaged to form a complete fixed threaded rod. Finally, the fixing nut 12 is installed on the fixed threaded rod to fix it, preventing the locking rod 19 from disengaging from the connection with the second locking hole 9, thus ensuring a tight connection between the two adjacent cable tray bodies. This utility model facilitates the docking and installation of adjacent cable tray bodies by workers, improves the connection strength and stability between the two cable tray bodies, and also improves the installation efficiency of workers.
