[0002] Currently available cable trays are categorized into trough type, tray type, ladder type, and mesh type structures, consisting of supports, brackets, and installation accessories. Cable trays within buildings can be installed independently or laid on various building structures and pipe rack supports, featuring simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. However, traditional cable trays suffer from drawbacks such as heavy weight, inconvenient installation, and lack of adjustable length or floor height, making them particularly unsuitable for complex cabling scenarios (such as data centers and industrial plants).

[0003] According to the public announcement (CN220857540U), a multi-layer composite cable tray structure for cable installation is disclosed. This technology discloses "a technical solution including an ultra-high voltage cable tray with a U-shaped structure composed of a bottom wall panel and a side wall panel, a bottom magnetic layer, a side magnetic layer, a high voltage cable tray, anchors, a low voltage cable tray, an alarm unit, a drainage system, and compartment components, etc. It has the technical effect that the overall horizontal cross-section of the structure is smaller than that of a general multi-layer multi-compartment cable tray, does not occupy a larger installation space, and is convenient for installation and dismantling."

[0004] In this existing design, ultra-high voltage cable trays, high voltage cable trays and low voltage cable trays are installed layer by layer from top to bottom. However, due to the problems of heavy weight, inconvenient installation, and non-adjustable length or layer height in the existing technology, it is particularly unsuitable for complex cabling scenarios (such as data centers and industrial plants).

[0005] To address these issues, a multi-layer, lightweight, and retractable cable tray structure was designed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1 As shown;

[0031] A multi-layer lightweight retractable cable tray structure.

[0032] In this implementation plan: In the prior art, ultra-high voltage cable trays, high voltage cable trays, and low voltage cable trays are arranged layer by layer from top to bottom. The trays are assembled by stacking, making full use of vertical space. Ultra-high voltage, high voltage, and low voltage cables can be laid layer by layer. The overall structure has a smaller horizontal cross-section than general multi-layer multi-compartment cable trays, so it does not occupy more installation space. The trays are assembled with anchors and magnetic connection structures, which is convenient for installation and disassembly and helps to be used flexibly and independently according to different cable installation needs. However, due to the problems of heavy weight, inconvenient installation, and non-adjustable length or layer height in the prior art, especially in complex wiring scenarios (such as data centers and industrial plants), the adaptability is poor. Therefore, a multi-layer lightweight and retractable cable tray structure is designed to solve the above problems.

[0033] Furthermore:

[0034] like Figures 1 to 3 As shown:

[0035] Based on the above: including a first cable tray 1, a second cable tray 2 is slidably connected to the surface of the first cable tray 1, a slide rail 3 is symmetrically fixedly connected to the upper surface of the second cable tray 2, and a limit groove 17 is symmetrically opened on the upper surface of the first cable tray 1. The slide rail 3 is slidably connected to the first cable tray 1 through the limit groove 17.

[0036] In this implementation scheme: a slide rail 3 is installed on the second cable tray 2, and a limiting groove 17 is symmetrically opened on the upper surface of the first cable tray 1, so that the first cable tray 1 and the second cable tray 2 can slide stably through the combination of the slide rail 3 and the limiting groove 17, so as to adjust the length of the cable tray.

[0037] Furthermore:

[0039] In an optional embodiment, a limiting rod 4 is symmetrically fixedly connected to the surface of the second cable tray 2, and the limiting rod 4 is slidably connected to the first cable tray 1 through a limiting groove 17.

[0040] In this embodiment: a limiting rod 4 is provided on the second cable tray 2, and the limiting rod 4 is limited by the limiting groove 17 to prevent the second cable tray 2 from sliding out of the first cable tray 1.

[0041] Furthermore:

[0042] like Figures 1 to 4 As shown:

[0043] In an optional embodiment, the surface of the second cable tray 2 is symmetrically fixedly connected with a slide rail 6, and the surface of each slide rail 6 is slidably connected with a sliding sleeve 5. The sliding sleeves 5 are all fixedly connected to the first cable tray 1. The surfaces of the first cable tray 1, the second cable tray 2, the sliding sleeves 5 and the slide rail 6 are symmetrically provided with a plurality of matching positioning holes 7. The first cable tray 1, the second cable tray 2, the sliding sleeves 5 and the slide rail 6 are all threadedly connected with positioning bolts 8 through the positioning holes 7.

[0044] In this embodiment: because the surface of the second cable tray 2 is symmetrically fixedly connected with slide rail 2 6, and the surface of slide rail 2 6 is slidably connected with slide sleeve 5, and the slide sleeve 5 is fixedly connected to the first cable tray 1, the surfaces of the first cable tray 1, the second cable tray 2, the slide sleeve 5 and the slide rail 2 6 are symmetrically provided with a number of matching positioning holes 7, and the first cable tray 1, the second cable tray 2, the slide sleeve 5 and the slide rail 2 6 are all threadedly connected with positioning bolts 8 through the positioning holes 7. By adopting this design, by adding slide rail 2 6 and slide sleeve 5, it is ensured that the first cable tray 1 and the second cable tray 2 can slide stably when the length of the first cable tray 1 and the second cable tray 2 is adjusted. The combination of positioning holes 7 and positioning bolts 8 fixes the first cable tray 1 and the second cable tray 2.

[0045] Furthermore:

[0046] like Figures 5 to 6 As shown:

[0047] In an optional embodiment, a first horizontal plate 10 is symmetrically arranged between the first cable tray 1 and the second cable tray 2, and a second horizontal plate 11 is slidably connected to the surface of the first horizontal plate 10. The first horizontal plate 10 and the second horizontal plate 11 are both slidably connected to the first cable tray 1 and the second cable tray 2.

[0048] In this embodiment, a first horizontal plate 10 and a second horizontal plate 11 are provided between the first cable tray 1 and the second cable tray 2. The double-layer design avoids interference by layering the wiring, improves space utilization, and facilitates maintenance. The first horizontal plate 10 and the second horizontal plate 11 can slide relative to each other to ensure that the first horizontal plate 10 and the second horizontal plate 11 can extend and retract accordingly when the first cable tray 1 and the second cable tray 2 are adjusted.

[0049] Furthermore:

The threaded rod 15 is threadedly connected to two of the connecting plates 12. The threaded rod 15 passes through the surface of the side housing 13 and is fixedly connected to a knob 16.

[0056] In this embodiment: A threaded rod 15 is rotatably connected to the inner surface of the other side housing 13. The threaded rod 15 is threadedly connected to two connecting plates 12. The threaded rod 15 passes through the surface of the side housing 13 and is fixedly connected to a knob 16. With this design, the threaded rod 15 is rotated by rotating the knob 16, so that the connecting plate 12 can move on the threaded rod 15, while limiting the position of the connecting plate 12.

[0057] Furthermore:

[0058] like Figures 1 to 6 As shown:

[0059] In an optional embodiment, the first cable tray 1 and the second cable tray 2, the first horizontal plate 10 and the second horizontal plate 11 are all designed to be embedded.

[0060] In this embodiment, since the first cable tray 1 and the second cable tray 2, the first horizontal plate 10 and the second horizontal plate 11 are all embedded, this design increases the load-bearing capacity and connection effect of the device.

[0061] Furthermore:

[0062] like Figures 1 to 6 As shown:

[0063] In an optional embodiment, heat dissipation vents 9 are provided on the surfaces of the first cable tray 1, the second cable tray 2, the first horizontal plate 10, and the second horizontal plate 11.

[0064] In this embodiment: since the surfaces of the first cable tray 1, the second cable tray 2, the first horizontal plate 10 and the second horizontal plate 11 are all provided with heat dissipation vents 9, this design can dissipate heat from the cables while also reducing the weight of the device, making it easier to transport.

[0065] Furthermore:

[0066] like Figures 1 to 6 As shown:

[0067] In an optional embodiment, the first cable tray 1, the second cable tray 2, the first cross plate 10, and the second cross plate 11 are all made of aluminum alloy.

[0068] In this embodiment, since the first cable tray 1, the second cable tray 2, the first horizontal plate 10 and the second horizontal plate 11 are all made of aluminum alloy, this design can enhance the strength of the device.

[0069] Working principle: A slide rail 3 is installed on the second cable tray 2. Limiting grooves 17 are symmetrically formed on the upper surface of the first cable tray 1, allowing the first cable tray 1 and the second cable tray 2 to slide stably through the combination of slide rail 3 and limiting grooves 17, thus adjusting the length of the cable trays. A limiting rod 4 is set on the second cable tray 2, and the limiting grooves 17 limit the limiting rod 4 to prevent the second cable tray 2 from sliding out of the first cable tray 1. Slide rails 6 are symmetrically and fixedly connected to the surface of the second cable tray 2, and sliding sleeves 5 are slidably connected to the surface of each slide rail 6. Each sliding sleeve 5 is fixedly connected to the first cable tray 1. Several matching positioning holes 7 are symmetrically formed on the surfaces of the first cable tray 1, the second cable tray 2, the sliding sleeves 5, and the slide rails 6. The second cable tray 2, sliding sleeve 5, and slide rail 6 are all threadedly connected to positioning bolts 8 through positioning holes 7. This design, by adding slide rail 6 and sliding sleeve 5, ensures stable sliding when adjusting the length of the first cable tray 1 and the second cable tray 2. The combination of positioning holes 7 and positioning bolts 8 fixes the first cable tray 1 and the second cable tray 2. A first horizontal plate 10 and a second horizontal plate 11 are installed between the first cable tray 1 and the second cable tray 2, adopting a double-layer design. Layered wiring avoids interference, improves space utilization, and facilitates maintenance. Furthermore, the first horizontal plate 10 and the second horizontal plate 11 can slide relative to each other, ensuring that the first horizontal plate 10 and the second horizontal plate 11 can extend and retract accordingly when adjusting the first cable tray 1 and the second cable tray 2. Connecting plates 12 are symmetrically fixedly connected to the surfaces of the first horizontal plate 10 and the second horizontal plate 11. Side shells 13 are symmetrically fixedly connected to the surfaces of the first cable tray 1 and the second cable tray 2. The connecting plates 12 and the side shells 13 are slidably connected. Sliding rods 14 are fixedly connected to the inner surfaces of the three side shells 13. The connecting plates 12 and the sliding rods 14 are slidably connected. This design allows for adjustment of the spacing between the first horizontal plate 10 and the second horizontal plate 11 to accommodate different cable sizes, further improving the overall applicability of the device. A threaded rod 15 is rotatably connected to the inner surface of another side shell 13. The threaded rod 15 is threadedly connected to two of the connecting plates 12. The threaded rod 15 penetrates the surface of the side shell 13 and is fixedly connected to a knob 1. 6. With this design, rotating the knob 16 drives the threaded rod 15 to rotate, allowing the connecting plate 12 to move on the threaded rod 15 and simultaneously limiting the position of the connecting plate 12. Since the first cable tray 1 and the second cable tray 2, the first horizontal plate 10 and the second horizontal plate 11 all adopt an embedded design, this design increases the load-bearing capacity and connection effect of the device. Since the surfaces of the first cable tray 1, the second cable tray 2, the first horizontal plate 10 and the second horizontal plate 11 are all provided with heat dissipation vents 9, this design can dissipate heat from the cables while also reducing the weight of the device for easier transportation. Since the first cable tray 1, the second cable tray 2, the first horizontal plate 10 and the second horizontal plate 11 are all made of aluminum alloy, this design can enhance the strength of the device.
