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

[0002] Cable trays, also known as cable management trays, are specialized equipment used in computer rooms for cable routing. They are metal frames used to bundle optical fibers and cables after entering the computer rooms of telecommunications, network, and broadcasting companies, allowing them to be routed to terminal equipment. Cable trays are primarily used for laying various cables inside and outside computer rooms and base stations. They are characterized by their attractive appearance, diverse styles, high strength, simple installation, and convenient cable routing.

[0003] Currently, conventional indoor cable trays are inconvenient for wiring. Conventional cable trays are usually either suspended or bottom-supported. Suspended cable trays are often obstructed by the hanging rods, while bottom-supported cable trays take up floor space, affecting the installation and wiring of equipment, or have insufficient capacity due to the large number of cables.

[0004] Therefore, there is an urgent need for a product that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems of existing cable trays being obstructed during wiring, taking up space, and having insufficient capacity when there are many cables.

[0006] To solve the above-mentioned technical problems, this utility model provides an adjustable cable tray, which adopts the following technical solution:

[0007] The adjustable cable tray includes a base ladder detachably mounted on the mounting surface and an adjustable ladder connected to the base ladder. The adjustable ladder can move laterally relative to the base ladder to adjust the width of the adjustable cable tray.

[0008] Optionally, the basic ladder frame includes a first main beam and a second main beam that are parallel to each other and spaced apart in the transverse direction, and a plurality of first crossbeams that are disposed between the first main beam and the second main beam and fixedly connected to both. Each first crossbeam is parallel to each other and spaced apart in the longitudinal direction. The fixed end of the first crossbeam is fixed to the first main beam, and the free end is placed on the second main beam.

[0009] Optionally, the adjustable ladder frame includes a third main beam and several second crossbeams. The third main beam and the second main beam are arranged parallel to each other, and the second crossbeams are arranged parallel to each other and spaced apart longitudinally. The fixed end of the second crossbeam is fixed to the third main beam, and the movable end is movably inserted into the first crossbeam from the free end of the corresponding first crossbeam to adjust the lateral distance between the third main beam and the second main beam.

[0010] Optionally, the bottom side of the first crossbar is provided with a strip-shaped notch, the strip-shaped notch is provided in a horizontal direction, and the bottom side of the second crossbar is provided with a locking pin, the locking pin being inserted into the strip-shaped notch.

[0011] Optionally, the adjustable cable tray further includes at least one support bracket for detachably mounting the base ladder on the mounting surface and several locking elements. The two first main beams are detachably mounted on the support bracket via the locking elements, and the support bracket is detachably mounted on the mounting surface via the locking elements.

[0012] Optionally, the support bracket includes a first support rod for supporting the foundation ladder and a second support rod for mounting the foundation ladder on the mounting surface.

[0035] This utility model embodiment provides an adjustable cable tray 100, such as... Figure 1As shown, the adjustable cable tray 100 includes a base ladder 10 and an adjustable ladder 20 connected to the base ladder 10. The base ladder 10 has a basic capacity to accommodate cables. The base ladder 10 is detachably mounted on an installation surface (such as a wall). This means that at the factory, the adjustable cable tray 100 only needs to be transported to the site, and then the adjustable cable tray 100 (specifically the base ladder 10) is installed on the installation surface. This allows for flexible arrangement according to the spatial structure and effectively avoids obstruction of installation by hangers or other obstacles. The adjustable ladder 20 can move laterally relative to the base ladder 10 to adjust the width of the adjustable cable tray 100. This width can be adjusted according to the actual cable capacity; the wider the overall width of the adjustable cable tray 100, the greater its upper limit for cable capacity.

[0036] Understandably, the installation principle of the adjustable cable tray 100 is roughly as follows:

[0037] When the product leaves the factory, the modular adjustable cable tray 100 is simply shipped to the site and flexibly arranged and installed on the mounting surface according to the spatial structure (specifically, the base ladder 10 is fixed on the mounting surface). When wiring, the adjustable ladder 20 is adjusted according to the actual cable capacity so that the overall width of the adjustable cable tray 100 can accommodate the cables. The entire construction workload is greatly reduced and can be completed and put into use quickly.

[0038] In summary, compared with existing technologies, this adjustable cable tray 100 has at least the following advantages:

[0039] The adjustable cable tray 100 is a unit module of the cable tray assembly. At the factory, the modular adjustable cable tray 100 is simply transported to the site and installed on the mounting surface. It allows for flexible arrangement according to the spatial structure, effectively avoiding installation obstructions from hangers or other obstacles. Furthermore, by adding more adjustable cable tray 100 unit modules according to the amount of cable, it effectively solves the problem of insufficient cable tray capacity. The base ladder 10 can be detachably installed on the mounting surface (such as a wall), effectively utilizing space and avoiding occupying floor space. The base ladder 10 has a basic capacity for accommodating cables, while the adjustable ladder 20 can move laterally relative to the base ladder 10 to adjust the width of the cable tray. This allows for adjustments to increase the upper limit of cable capacity beyond the basic capacity of the base ladder 10, facilitating product adjustments based on actual cable capacity and offering high flexibility.

[0040] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0041] In some embodiments, both the base ladder 10 and the adjustable ladder 20 may be made of aluminum alloy or other metal materials.

[0042] In some embodiments, such as Figure 1 As shown, the basic ladder frame 10 includes a first main beam 11 and a second main beam 12 arranged parallel to each other and spaced apart laterally, and a plurality of first crossbeams 13 arranged between and fixedly connected to the first main beams 11 and 12. Both the first main beams 11 and 12 are hollow tubular structures to provide space for accommodating wires. The first crossbeams 13 are arranged parallel to each other and spaced apart longitudinally. The fixed end of each first crossbeam 13 can be fixed to the first main beam 11, and the free end can be placed on the second main beam 12. In other words, the first main beams 11, 12, and the plurality of first crossbeams 13 constitute a ladder frame structure. Understandably, the thickness of the second main beam 12 is less than the thickness of the first main beam 11, so that when the fixed end of each first crossbeam 13 is fixed to the first main beam 11 and the free end is placed on the second main beam 12, the first crossbeam 13 can be in a horizontal state.

[0043] In some embodiments, such as Figure 1 As shown, the adjustable ladder frame 20 includes a third main beam 21 and several second crossbars 22. The third main beam 21 is configured as a hollow tubular structure to provide space for accommodating wires. The third main beam 21 can be arranged parallel to the second main beam 12. The second crossbars 22 can be arranged parallel to each other and spaced apart longitudinally. The fixed end of the second crossbar 22 can be fixed to the third main beam 21, and the movable end can be movably inserted into the corresponding first crossbar 13 from its free end to adjust the lateral distance between the third main beam 21 and the second main beam 12. Based on this, both the first crossbar 13 and the second crossbar 22 are configured as hollow tubular structures. The hollow tubular structure of the first crossbar 13 allows the second crossbar 22 to be inserted into it, and the hollow tubular structure of the second crossbar 22 provides space for accommodating wires. Understandably, the adjustable ladder rack 20, as a lateral extension of the basic ladder rack 10, allows for a wider overall width adjustment of the adjustable cable tray 100, resulting in a higher upper limit for cable capacity.

[0044] In some embodiments, such as Figure 2As shown, a strip-shaped notch 131 may be provided on the bottom side of the first horizontal rung 13. This strip-shaped notch 131 may be provided in the transverse direction (i.e., the length direction of the first horizontal rung 13). A locking pin 221 may be provided on the bottom side of the second horizontal rung 22, and the locking pin 221 may be inserted into the strip-shaped notch 131. It can be understood that when the adjustable ladder frame 20 is adjusted to a suitable position, the second horizontal rung 22 and the first horizontal rung 13 can be locked in a locked state by extending the locking pin 221 from the strip-shaped notch 131, preventing the second horizontal rung 22 from moving relative to the first horizontal rung 13. It should be noted that the bottom side of the first horizontal rung 13 and the bottom side of the second horizontal rung 22 are defined as the side of the first horizontal rung 13 and the second horizontal rung 22 facing downwards when the base ladder frame 10 and the adjustable ladder frame 20 are installed on the mounting surface.

[0045] In some embodiments, such as Figure 2 As shown, the strip notch 131 can extend to both the fixed and free ends of the first crossbar 13 to maximize the travel of the adjustable ladder frame 20. Furthermore, the width of the strip notch 131 cannot be too wide to ensure that the second crossbar 22 does not detach from the strip notch 131.

[0046] In some embodiments, such as Figure 1 As shown, the adjustable cable tray 100 also includes at least one support bracket 30 for detachably mounting the base ladder 10 to the mounting surface and several locking elements (not shown in the figure), which may be locking screws. Two first main beams 11 can be detachably mounted on the support bracket 30 via the locking elements, and the support bracket 30 can be detachably mounted on the mounting surface via the locking elements. Understandably, the base ladder 10 (and the adjustable ladder 20 connected to the base ladder 10) and the support bracket 30 are separate structures. When the product leaves the factory, only the base ladder 10 (and the adjustable ladder 20 connected to the base ladder 10) and the support bracket 30 need to be shipped separately to the site. During installation, the support bracket is first fixed to the mounting surface via the locking elements, and then the base ladder 10 (and the adjustable ladder 20 connected to the base ladder 10) is fixed to the support bracket 30 via the locking elements. This greatly reduces the amount of construction work and allows for rapid completion and commissioning.

[0047] In some embodiments, as one implementation of the support bracket 30, such as Figure 1 and Figure 3 As shown, the support bracket 30a includes a first support rod 31a for supporting the foundation ladder 10 and a second support rod 32a for mounting the foundation ladder 10 on the mounting surface. The second support rod 32a can be vertically mounted on one end of the first support rod 31a. The two first main beams 11 can be detachably mounted on the first support rod 31a via locking devices. The second support rod 32a can be detachably mounted on the mounting surface via locking devices to complete the installation of the adjustable cable tray 100.

[0048] In some embodiments, such as Figure 1 and Figure 3 As shown, the support bracket 30a also includes a reinforcing rod 33a. The two ends of the reinforcing rod 33a can be fixed to the first rod 31a and the second rod 32a respectively to form a triangular frame structure and enhance the stability of the support.

[0049] In some embodiments, such as Figure 3 As shown, at least one reinforcing rib 34a may be provided between the reinforcing support rod 33a and the first support rod 31a and the second support rod 32a to further enhance the stability of the support.

[0050] In some embodiments, as another implementation of the support bracket 30, such as Figure 1 and Figure 4 As shown, the support bracket 30b can be configured as a right-angled triangular support plate. Understandably, the two first main beams 11 can be detachably mounted on one right-angled side of the support bracket 30b via locking devices, and the other right-angled side of the support bracket 30b can be detachably mounted on the mounting surface via locking devices to complete the installation of the adjustable cable tray 100.

[0051] In some embodiments, the first main beam 11, the second main beam 12, the third main beam 21, the first crossbeam 13, and the second crossbeam 22 can be configured as rectangular tubes or circular tubes, and the specific design can be based on actual requirements.

[0052] Based on the aforementioned adjustable cable tray 100, this utility model embodiment also provides a cable tray assembly, which includes a plurality of the aforementioned adjustable cable trays 100, each adjustable cable tray 100 being able to be connected end-to-end with adjacent adjustable cable trays 100.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
