Description

Technical Field

[0001] This utility model relates to the field of cable equipment technology, and in particular to an adjustable cable tray. Background Technology

[0002] Cable trays are supporting devices used for laying cables, widely used in industrial, commercial, and civil buildings to provide mechanical protection and support for cables. Cable trays are typically made of metal or non-metal materials, featuring lightweight construction, easy installation, and simple maintenance. Types include trough-type, ladder-type, and tray-type cable trays, with different forms available depending on specific needs. Cable trays effectively organize and manage cable wiring, reducing cable damage and improving wiring efficiency and safety.

[0003] Existing cable trays typically employ a fixed height design, which presents significant problems when height adjustments are needed to accommodate different construction environments or wiring layouts. Specifically, because the tray height is not adjustable, construction workers often need to add extra support structures or make cumbersome modifications to meet installation requirements, increasing both construction complexity and costs. Furthermore, the inability to flexibly adjust the height of cable trays can lead to inconvenience or even make installation impossible when faced with complex wiring layouts or space constraints, severely impacting the adaptability and efficiency of cable trays in practical applications.

[0025] Example

[0026] Reference Figures 1-6 This embodiment provides a height-adjustable cable tray, including a tray body 1 for carrying and supporting cables. To enable height adjustment of the tray body 1, fixing rods 2 are provided at each of its four outer corners. The fixing rods 2 serve as supports and guides, ensuring the stability of the entire structure. A fixing plate 3 is fixedly installed at the top of the fixing rod 2. The fixing plate 3 not only serves to fix the overall frame but also provides a mounting base for other transmission components.

[0027] Inside each fixed rod 2, a threaded rod 4 is rotatably connected. The function of the threaded rod 4 is to achieve lifting and lowering adjustment by rotation, which, together with the lifting block 9, moves the cable tray body 1 vertically. The top end of the threaded rod 4 penetrates the inner top wall of the fixed rod 2 and extends into the interior of the fixed plate 3, where it is fixedly connected to the driven conical tooth 5. The function of the driven conical tooth 5 is to receive power transmission and drive the threaded rod 4 to rotate.

[0028] Each driven bevel tooth 5 is meshed with a driving bevel tooth 6 on its upper side. The function of the driving bevel tooth 6 is to transmit power to the driven bevel teeth 5, thereby driving the threaded rod 4 to rotate synchronously and achieve lifting and lowering adjustment. A rotating shaft 7 is provided between the two driving bevel teeth 6 on the left and between the two driving bevel teeth 6 on the right. The rotating shaft 7 is fixedly connected to the driving bevel teeth 6 to transmit rotational power and ensure that the two driving bevel teeth 6 on the same side rotate synchronously, thereby ensuring the synchronous movement of the four threaded rods 4 and maintaining the stability of the lifting and lowering process.

[0029] A transmission assembly 8 is disposed between the two rotating shafts 7. The transmission assembly 8 includes a knob 801 located directly in front of the outside of the fixed plate 3. The knob 801 is the main control component for user operation; the entire lifting system can be driven by manually rotating the knob 801. A rotating rod 802 is fixedly connected to the rear end of the knob 801, and the rotating rod 802 transmits the rotational movement of the knob to the interior of the fixed plate 3. The rear end of the rotating rod 802 penetrates the outer wall of the fixed plate 3 and extends into the second cavity 302 inside the fixed plate 3, where it is fixedly connected to the drive wheel 803.

[0030] The outer surface of the drive wheel 803 is meshed with the track 804. The function of the track 804 is to transmit the rotational motion of the drive wheel 803 to the driven wheels 805 at both ends, achieving synchronous power distribution. Driven wheels 805 are meshed with the inner sides of both ends of the track 804. The driven wheels 805 transmit the motion of the track to the two rotating shafts 7, causing the driving bevel teeth 6 on both sides to rotate synchronously, thereby driving the threaded rod 4 to rotate.

[0031] In addition, the rotating rod 802 and the two rotating shafts 7 are rotatably connected to the inner wall of the fixed plate 3 through the bearings 10. The bearings 10 play a supporting role and reduce friction, ensuring smooth and stable rotation.

[0032] To further improve the stability and convenience of the cable tray during installation, hangers 11 are fixedly installed at the four corners of the top of the fixing plate 3 to facilitate the installation or hoisting of the cable tray.

[0033] Each of the four threaded rods 4 has a lifting block 9 threadedly connected to its outer surface. The lifting block 9 engages with the threaded rod 4, and when the threaded rod 4 rotates, the lifting block 9 moves up and down along the threaded rod. The inner ends of the four lifting blocks 9 are fixedly connected to the outer wall of the cable tray body 1. When the lifting block 9 rises or falls, it drives the cable tray body 1 to rise and fall accordingly.

[0034] In summary, by rotating knob 801, the entire transmission system can be driven to work synchronously, achieving synchronous rotation of the four threaded rods 4, thereby enabling the cable tray body 1 to rise and fall smoothly. The entire device has a compact structure, is easy to operate, and can flexibly adjust its height to adapt to different construction environments, significantly improving the installation efficiency and applicability of cable trays.
