Description

Technical Field

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

[0002] Currently, a major problem facing cable tray technology is the lack of scalability in conventional cable covers and cable tray boxes. This means that when a system needs to be expanded in the future, the cable trays often cannot directly accommodate the additional cables. Common solutions to this situation are to replace the entire cable tray or to lay new cable channels alongside existing facilities to meet the expansion requirements. Both methods not only increase costs but may also be difficult to implement due to site space constraints and increased construction complexity.

[0003] Therefore, there is an urgent need for a new type of cable tray design that can expand the cable channel capacity by increasing the width or height of the cable channel when the capacity is insufficient to support expansion. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an expandable cable tray structure to address the above-mentioned problems.

[0005] The technical solution adopted in this utility model is: an expandable cable tray structure, comprising: The cable tray assembly has a cable channel inside for laying cables; A cover plate assembly is located on top of the slot assembly. The two sides of the cover plate assembly are connected to the two sides of the slot assembly. The interior of the cover plate assembly has an extension layer located above the cable channel and capable of laying cables.

[0006] Through the above-mentioned technical means, cables can be laid inside the slot assembly using cable channels, and an extension layer can be added to the top of the slot assembly using the cover plate assembly, thereby adding cables and achieving depth expansion while retaining the slot assembly.

[0007] In some embodiments, the cover plate assembly includes an extended cover plate, a fixed beam, a support beam, and a connector. The support beam is connected to the fixed beam on at least one side. The fixed beam, the side wall of the slot assembly, and the side wall of the extended cover plate are correspondingly connected via the connector. The preset depth of the extended cover plate is greater than the depth of the slot assembly, such that the bottom of the support beam and the interior of the slot assembly cooperate to form a cable channel for laying cables, and the top of the support beam and the interior of the extended cover plate cooperate to form an extended layer for laying cables.

[0008] In some embodiments, symmetrically arranged cable anti-slip beams are also provided on both sides of the top of the support beam.

[0009] In some embodiments, the connector includes bolts, and the fixing beam, the extension cover plate, and the slot assembly are provided with corresponding threaded holes, and the fixing beam, the extension cover plate, and the slot assembly are connected by bolts.

[0010] In some embodiments, the slot box assembly includes an extension box plate, a first buckle, a second buckle, and an extension side plate. The extension side plate has an L-shaped structure. The extension box plate has a crease, and the first buckle is located at the crease. The side of the extension side plate has a second buckle, and the second buckle and the first buckle can be detachably connected.

[0011] In some embodiments, a third latch is provided on the side of the expansion box plate, which is used to position the second latch.

[0012] In some embodiments, the slot box assembly includes an initial state and an expanded state. When the slot box assembly is in the initial state, the expanded box plate is bent along the crease and is in a vertically folded state. When the slot box assembly is in the expanded state, the expansion box plate is in the horizontally unfolded state. The two sides of the expansion box plate are connected to expansion side plates via the first buckle and the second buckle. The expansion side plates can be connected to the cover plate assembly after the expansion is preset in width.

[0013] In some embodiments, the cover plate assembly with the extended preset width includes multiple conventional cover plates and a fourth snap fastener. The multiple conventional cover plates are horizontally detachably connected to each other via the fourth snap fastener, so that the splicing width of the multiple conventional cover plates corresponds to the width of the extended box plate.

[0014] In some embodiments, the first buckle is an L-shaped metal hook with an elastic barb at the end, and the second buckle is a U-shaped groove with a groove inside that matches the barb. The width of the U-shaped groove is greater than the width of the hook part of the L-shaped metal hook.

[0015] The beneficial effects of this utility model are: 1. By adding a cover plate assembly to the top of the cable tray assembly, which contains a cable channel, and an extension layer located above the cable channel, the cable laying space is increased. This allows for capacity expansion without replacing the original cover plate with the cover plate assembly, or by adding extension layers or splicing extension components to the cable tray, significantly reducing modification costs and construction difficulty.

The use of the phrase "in one embodiment" or "in an embodiment" does not necessarily refer to the same embodiment. Specific features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

[0027] The term "comprising" is open-ended. As used in the appended claims, it does not exclude additional structures or steps.

[0028] "First," "second," etc. As used in this article, these terms serve as labels for the nouns preceding them and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). Detailed Implementation

[0029] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0030] Combination Figure 1 and Figure 2 As shown, the conventional slot box 2 and the conventional cover plate 1 cooperate with each other and cannot be expanded normally.

[0031] Example 1: Combination Figure 3 , Figure 4 and Figure 5 As shown, this embodiment is an expandable cable tray structure, including a conventional cable tray 2 and a cover assembly 3. The cover assembly 3 is located on top of the conventional cable tray 2, and its two sides are correspondingly connected to the two sides of the conventional cable tray 2. The conventional cable tray 2 has a cable channel inside that can be used to lay cables. The cover assembly 3 is higher than the conventional cable tray 2 by a preset height, and an extension layer is formed inside the cover assembly 3 above the cable channel. The extension layer can additionally lay cables above the cable channel and provide support for the cables, thereby expanding the capacity of the conventional cable tray 2 in the depth direction.

[0032] In some implementations, the cover assembly 3 includes an extension cover 5, a fixing beam 6, a support beam 7, and connectors. At least one side of the support beam 7 is connected to the fixing beam 6. The fixing beam 6 is connected to the side wall of the conventional cable tray 2 via connectors. Both sides of the extension cover 5 are connected to the two side walls of the conventional cable tray 2 via connectors. The preset depth of the extension cover 5 is greater than the depth of the conventional cable tray 2, so that the bottom of the support beam 7 and the interior of the conventional cable tray 2 cooperate to form a cable channel for cable laying, and the top of the support beam 7 and the interior of the extension cover 5 cooperate to form an extension layer for cable laying. Specifically, in this embodiment, the extension cover 5 has a U-shaped structure, and the support beam 7 and the two fixing beams 6 cooperate to form a U-shaped structure. In this embodiment, the support beam 7 can be designed with a single-sided fixing beam 6. Because the width of the extension layer formed at the top is smaller than the width of the original bottom cable tray to ensure heat dissipation and ease of maintenance of the cables inside the original bottom cable tray, the support is designed to be single-sided.

[0033] Furthermore, symmetrically arranged cable anti-slip beams 9 are provided on both sides of the top of the support beam 7. Specifically, the cable anti-slip beams 9 are transversely protruding strip structures distributed on both sides of the cable tray, forming "limiting grooves" for the cables. The surface of the cable anti-slip beams 9 is made of serrated texture or rubber coating to increase the coefficient of friction with the cable sheath.

[0034] By setting up anti-slip beams 9, the cables can be positioned and pressure can be distributed. On the one hand, they mainly prevent the cables from shifting laterally or slipping when they are vibrated, tilted or dragged by external forces in the cable tray, thus ensuring that the cables are arranged in an orderly manner. On the other hand, by using multiple points of contact, the local pressure of the cable weight on the cable tray base plate is reduced, thus avoiding deformation caused by long-term compression.

[0035] Furthermore, the connecting components include bolts, and the fixing beam 6, the extension cover plate 5 and the conventional slot box 2 are provided with corresponding threaded holes 8, and the fixing beam 6, the extension cover plate 5 and the conventional slot box 2 are connected by bolts.

[0036] By employing cover plate assembly 3, an extension layer is constructed using the space above the cable tray, increasing cable laying space above the original cable trays and achieving longitudinal expansion. The fixed beam 6 and supporting beam 7 work together to provide additional support, ensuring the structural strength of the extension layer. All connections are bolted, and the detachable structure facilitates maintenance and future expansion.

[0037] Example 2: Combination Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, this embodiment is an expandable cable tray structure, including a conventional cover plate 1 and a cable tray assembly 4. The conventional cover plate 1 is located on top of the cable tray assembly 4. The cable tray assembly 4 has a cable channel inside for laying cables. The cable tray assembly 4 can be reassembled to expand its internal width. The conventional cover plate 1 can be prefabricated according to a preset expansion width to accommodate the expanded cable tray assembly 4, thereby realizing the expansion of the cable tray in the width direction.

[0038] In some implementation schemes, such as Figure 6 , Figure 7 and Figure 8 As shown, the slot box assembly 4 includes an expansion box plate 10, a first buckle 11, a second buckle 12, and an expansion side plate 13. The expansion side plate 13 has an L-shaped structure. The expansion box plate 10 has a crease, and the first buckle 11 is provided at the crease. The second buckle 12 is provided on the side of the expansion side plate 13. The second buckle 12 and the first buckle 11 can be detachably connected.

[0039] Furthermore, the first buckle 11 adopts an L-shaped metal hook with a flexible barb at the end, and the second buckle 12 adopts a U-shaped groove with an internal groove for the barb to engage. The width of the U-shaped groove is slightly larger than the width of the hook of the L-shaped metal hook, allowing the groove to accommodate the hook and permitting slight displacement to absorb vibration. The first buckle 11 and the second buckle 12 interlock vertically through the groove and barb to prevent the cable tray from disengaging. The barb design ensures that pressing is required to unlock after engagement, enhancing shock resistance. In this embodiment, both the first buckle 11 and the second buckle 12 are conventional buckle-fitting structures, so the specific structure is only briefly illustrated in the accompanying drawings and is not shown.

[0040] Furthermore, a third latch 14 is provided on the side of the expansion box plate 10. The third latch is used to position the second latch. The third latch 14 is mainly used for lateral positioning during the initial installation to ensure that the expansion side plate 13 is aligned with the expansion box plate 10 and to avoid misalignment.

[0041] The slot box assembly 4 includes an initial state and an expanded state. When the slot box assembly 4 is in the initial state, the expansion box plate 10 is bent along the crease and is in a vertical folded state, that is, the expansion box plate 10 is U-shaped and can be connected to the conventional cover plate 1.

[0042] When the cable tray assembly 4 is in the expanded state, the expansion box plate 10 is in a horizontally unfolded state. The expansion box plate 10 is connected to an expansion side plate 13 on at least one side, which can realize the expansion of the cable channel in the width direction. Specifically, in this embodiment, the expansion box plate 10 is symmetrically provided with two folds. The expansion side plates 13 are connected to both sides of the expansion box plate via the first buckle 11 and the second buckle 12. The expansion box plate 10 and the expansion side plates 13 on both sides cooperate to form a U-shape. The expansion side plates 13 can be connected to the cover plate assembly 3 after the preset width has been expanded.

[0043] Furthermore, such as Figure 9 As shown, the cover assembly 3 after expanding the preset width includes multiple conventional cover plates 1 and a fourth snap fastener 15. The multiple conventional cover plates 1 are horizontally detachably connected to each other via the fourth snap fastener 15, so that the splicing width of the multiple conventional cover plates 1 corresponds to the width of the expansion box plate 10. The expansion and quick connection of the conventional cover plates 1 are realized through the snap fastener movement interlock logic.

[0044] The expansion panel 10 serves as the initial cable tray structure. When expansion is needed, the expansion panel 10 unfolds and connects with the expansion side panel 13 to achieve lateral expansion of the cable tray. Both sides can be expanded to form a wider cable channel, making it suitable for scenarios with available lateral space. The snap-fit ​​structure facilitates quick fixation of the expansion configuration, making installation and disassembly convenient.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
