[0002] Aluminum alloy trough-type cable trays are a type of fully enclosed cable tray suitable for laying computer cables, communication cables, thermocouple cables, and control cables for other highly sensitive systems. They offer good shielding against interference and protection for cables in heavily corrosive environments.

[0003] Most aluminum alloy cable trays currently on the market are similar in overall structure, consisting of a bottom trough and a top cover. Cables pass through the trough, and the cover is placed on top of the trough to protect the internal cables. However, there are some functional shortcomings in actual use, which have room for improvement. For example, the overall height of the trough is fixed. When multiple layers of cables need to be placed inside the trough, there will be insufficient space, requiring the installation of two layers of cable trays, which increases costs. Also, it does not have the function of easy extension and height adjustment.

[0004] Now, a novel retractable aluminum alloy trough-type cable tray is proposed to solve the above problems. Utility Model Content

Positioning bolt rods 2 are respectively welded to the front and rear ends of the outer side of the telescopic inner lining 6. Locking nuts 3 are sleeved on the outside of the positioning bolt rods 2. Rubber gaskets 4 are provided between the lower trough body 1 and the locking nuts 3.

[0025] The positioning bolt rod 2 passes through the sliding adjustment groove 5 and extends to the outside. The positioning bolt rod 2 can slide up and down along the inside of the sliding adjustment groove 5. The internal thread of the locking nut 3 matches the external thread of the positioning bolt rod 2. The rubber gasket 4 is sleeved on the outside of the positioning bolt rod 2. The telescopic liner 6 is symmetrically distributed about the vertical center line of the lower groove 1. The telescopic liner 6 can slide up and down along the inner side of the lower groove 1 and can be telescopically adjusted.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, loosen the locking nut 3. The locking nut 3, together with the rubber gasket 4, and the lower groove 1 are no longer tightly pressed together. Then, the telescopic liner 6 can be pulled up. The positioning bolt rod 2 will move up along the sliding adjustment groove 5. After adjusting to the appropriate height, tighten the locking nut 3 again. The rubber gasket 4 will press against the lower groove 1 to fix the height of the telescopic liner 6.

[0027] The lower tank 1 has two sets of upper pressure plates 8 inside. The bottom of the upper pressure plate 8 is glued with an upper pressure block 9. The lower support plate 11 is set below the upper pressure plate 8. The top of the lower support plate 11 is glued with a lower support block 10. The upper pressure plate 8 and the lower support plate 11 have two sets of countersunk screw holes 12 on both sides of the top. The upper pressure block 9 and the lower support block 10 have multiple sets of cable grooves 13 on their opposite sides. The upper pressure plate 8 and the lower support plate 11 have the same shape and size. The upper pressure block 9 and the lower support block 10 have the same shape and size. The countersunk screw holes 12 pass through the interior of the upper pressure block 9 and the lower support block 10 to facilitate clamping and fixing the cable.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the upper pressure block 9 and the lower support block 10 clamp the cable, and the cable groove 13 facilitates cable positioning. The countersunk screw is driven into the countersunk screw hole 12 on the upper pressure plate 8. The screw passes through the upper pressure plate 8 and extends into the countersunk screw hole 12 in the lower support plate 11, and the cable is clamped.

[0029] Two sets of bottom support plates 14 are provided below the lower tank body 1. Side support plates 15 are welded to the top of the bottom support plates 14 on both sides respectively. Two sets of fixing bolts 16 are inserted into the side support plates 15. Multiple sets of positioning screw holes 17 are opened on the left and right sides of the lower tank body 1. The fixing bolts 16 pass through the side support plates 15 and extend into the interior of the positioning screw holes 17. The positioning screw holes 17 are arranged at equal intervals to facilitate raising the tank body.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, loosen the fixing bolt 16 to disengage it from the positioning screw hole 17, pull down the bottom support plate 14, and the side support plate 15 moves down along the outside of the lower groove 1.

When multiple layers of cable need to pass through the lower groove 1, the telescopic liner 6 can be raised, and the locking nut 3 can be loosened. The locking nut 3, together with the rubber gasket 4, is no longer pressed against the lower groove 1, allowing the telescopic liner 6 to be pulled up. The positioning bolt rod 2 then moves upward along the sliding adjustment groove 5. After adjusting to the appropriate height, the locking nut 3 is tightened again, and the rubber gasket 4 presses against the lower groove 1 to fix the height of the telescopic liner 6. As the cable passes through the lower groove 1, the upper pressure block 9 and the lower support block 10 clamp the cable. The cable groove 13 facilitates cable positioning. Countersunk screws are driven into the countersunk screw holes 12 on the upper pressure plate 8. The screws penetrate the upper pressure plate 8 and extend into the countersunk screw holes 12 in the lower support plate 11, thus clamping the cable. When the lower tank 1 needs to be raised according to the installation requirements, loosen the fixing bolt 16 to disengage it from the positioning screw hole 17, pull down the bottom support plate 14, and the side support plate 15 moves down along the outside of the lower tank 1. After reaching the appropriate position, tighten the fixing bolt 16 again. The fixing bolt 16 will then be inserted into the positioning screw hole 17, and the positions of the bottom support plate 14 and the side support plate 15 will be fixed, thus raising the lower tank 1.
