[0032] The following further elaborates on this application Figures 1-4 in conjunction with the attached drawings.

[0033] An embodiment of this application discloses an assembled cable tray. Referring to Figure 1 and Figure 2 , the assembled cable tray includes a plurality of hangers installed on the bottom surface of the floor slab or the ceiling, a plurality of trough cable tray bodies 1 that can be spliced with each other and are supported by the hangers, and a trough cover 2 covering the upper opening of each trough cable tray body 1; each trough cable tray body 1 is supported by two adjacent hangers; a slide hole 11 in an L shape is opened at the side end of the trough cable tray body 1, and a sliding member slidably connected to the slide hole 11 is fixedly connected to the other end of the side of the trough cable tray body 1. The sliding member of the previous trough cable tray body 1 is slidably connected to the slide hole 11 of the next trough cable tray body 1 to realize the connection between two adjacent trough cable tray bodies 1. A locking assembly for locking the sliding member in the slide hole 11 is arranged on the side of the trough cable tray body 1.

[0034] Each hanger includes two suspension rods 3 that are parallel to each other and vertically installed on the bottom surface of the floor slab or the ceiling, and a cross arm 31 that is detachably connected between the two suspension rods 3 and is horizontally arranged. Expansion bolts with fixed nuts are embedded in the bottom surface of the floor slab or the ceiling. The expansion bolts are driven into the bottom surface of the floor slab or the ceiling, and the bottom ends of the expansion bolts extend below the floor slab or the ceiling. A horizontally arranged connecting block 32 is fixedly connected to the top end of the suspension rod 3. The bottom end of the expansion bolt penetrates through the connecting block 32. By threadedly connecting the fixed nut with the expansion bolt until the top surface of the fixed nut abuts against the bottom surface of the connecting block 32, the connecting block 32 is installed on the expansion bolt, thereby realizing the installation of the suspension rod 3 on the bottom surface of the floor slab or the ceiling.

[0035] External threads are provided on the circumferential side of the suspension rod 3, and two locking nuts 33 are threadedly connected up and down on the suspension rod 3; in this embodiment, the cross arm 31 is an angle steel. The horizontal side top surface of the angle steel supports the trough cable tray body 1, and the trough cable tray body 1 is located between the two suspension rods 3; the bottom end of the suspension rod 3 vertically penetrates through the horizontal side of the angle steel, and the two locking nuts 33 respectively abut against the horizontal side top surface and the horizontal side bottom surface of the angle steel.

[0036] Reference Figure 3 and Figure 4 On both top sides of the trough - type cable tray body 1, first clamping portions 14 that are bent outward integrally are formed. On both sides of the trough cover 2, second clamping portions 21 that are bent inward integrally are formed. The second clamping portions 21 are elastically clamped with the correspondingly - positioned first clamping portions 14 to cover the trough cover 2 on the upper opening of the trough - type cable tray body 1.

[0037] The sliding member includes a long strip - shaped cross - block 12 fixedly connected to the side end of the trough - type cable tray body 1 and a locking block 13 fixedly connected perpendicularly to one end of the long strip - shaped cross - block 12 away from the trough - type cable tray body 1. A locking hole 131 is formed in the locking block 13. Both the long strip - shaped cross - block 12 and the locking block 13 are slidably connected to the sliding hole 11. The long strip - shaped cross - block 12 and the locking block 13 slide into the sliding hole 11 along the lateral side of the sliding hole 11. When the locking block 13 slides to the vertical side of the sliding hole 11, the locking block 13 is clamped with the sliding hole 11 so that two adjacent trough - type cable tray bodies 1 cannot move away from each other in the direction away from each other. The locking end of the locking assembly is inserted and matched with the locking hole 131 to lock the locking block 13 in the sliding hole 11.

[0038] The locking assembly includes a fixed shell 4 fixedly connected to the side of the trough - type cable tray body 1 and adjacent to the vertical side of the sliding hole 11, a sliding block 41 slidably connected in the fixed shell 4, a locking rod 42 fixedly connected to the side of the sliding block 41 close to the locking block 13 and inserted and matched with the locking hole 131, and a spring 43 fixedly connected to the side of the sliding block 41 away from the locking rod 42. One side of the fixed shell 4 away from the trough - type cable tray body 1 is open - set, and the sliding block 41 extends out of the fixed shell 4 through the opening of the fixed shell 4. One end of the spring 43 away from the sliding block 41 is fixedly connected to the inner end wall of the fixed shell 4. In order to enable the sliding block 41 to slide more smoothly in the fixed shell 4, a first sliding groove 44 is formed in the inner bottom wall of the fixed shell 4. The length direction of the first sliding groove 44 is the same as the length direction of the locking rod 42. A first sliding block slidably connected to the first sliding groove 44 is fixedly connected to the bottom surface of the sliding block 41.

[0039] Reference Figure 3 and Figure 4, in order to limit the sliding block 41, a vertically arranged vertical plate 45 is fixedly connected to the top surface of the fixed shell 4. A limiting plate 46 is slidably connected to the vertical plate 45, and a limiting opening 461 for clamping the sliding block 41 is formed in the limiting plate 46. After the locking rod 42 is inserted and matched with the locking hole 131, the limiting plate 46 limits the sliding block 41 so that the sliding block 41 cannot move towards the direction close to the spring 43. Move the limiting plate 46 upward to disengage the limiting plate 46 from abutting against the sliding block 41, and then move the sliding block 41 towards the direction close to the spring 43 until the locking rod 42 disengages from the locking hole 131. At this time, the sliding block 41 is located below the limiting opening 461, and then move the limiting plate 46 downward so that the limiting opening 461 is clamped with the sliding block 41, thereby achieving the limiting effect on the locking rod 42.

[0040] Referring to Figure 3 and Figure 4 , in order to enable the limiting plate 46 to slide more smoothly with the vertical plate 45, a vertical second sliding groove 451 is formed on the side of the vertical plate 45 close to the limiting plate 46. A second sliding block slidably connected to the second sliding groove 451 is fixedly connected to the side of the limiting plate 46 close to the vertical plate 45. Both the second sliding block and the second sliding groove 451 are in the shape of a dovetail, so that the second sliding block cannot fall off from the second sliding groove 451.

[0041] The implementation principle of an assembled cable tray in an embodiment of the present application is as follows: When it is necessary to complete the splicing of two adjacent trough cable tray bodies 1, the long strip cross block 12 and the locking block 13 are slid into the sliding hole 11 along the lateral side of the sliding hole 11, and the locking block 13 is slid to the vertical side of the sliding hole 11. When the locking block 13 is slid to the vertical side of the sliding hole 11, the locking block 13 is clamped with the sliding hole 11 so that the two adjacent trough cable tray bodies 1 cannot move away from each other; Move the limiting plate 46 upward. Under the reset action of the spring 43, the sliding block 41 drives the locking rod 42 to be inserted and matched with the locking hole 131 to lock the locking block 13 in the sliding hole 11, and the limiting plate 46 abuts against the sliding block 41 to limit the sliding block 41, thereby realizing the splicing between two adjacent trough cable tray bodies 1.

[0042] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
