[0048] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0049] Example 1

[0050] like Figures 2-4 As shown in the figure, this utility model application provides a cable tray structure, which includes a first cable tray 1. The first cable tray 1 includes a first horizontal plate 11 and a second horizontal plate 12, and two first side plates 13 fixed to one side of the first horizontal plate 11 and the second horizontal plate 12. The two first side plates 13 are symmetrically arranged, and the first horizontal plate 11 and the second horizontal plate 12 are both located between the two first side plates 13. The first horizontal plate 11 and the second horizontal plate 12 are slidably engaged by a pull-in structure, thereby changing the distance between the two first side plates 13 to achieve adjustable width of the cable tray structure.

[0051] Specifically,

[0052] The first horizontal plate 11 is provided with a plurality of first through slots 111, which are spaced apart along the length of the first horizontal plate 11, so that a first insertion part 112 is formed between each two adjacent first through slots 111. The first through slots 111 are arranged vertically and open towards the second horizontal plate 12.

[0053] The second horizontal plate 12 is provided with a first slot 121 that matches the first horizontal plate 11. Specifically, the second horizontal plate 12 is provided with a plurality of first slots 121, and the positions of the plurality of first slots 121 correspond one-to-one with the positions of the plurality of first plug-in parts 112. The first plug-in parts 112 can be movably inserted into the first slots 121, thereby forming the aforementioned insert-and-pull structure between the first plug-in parts 112 and the first slots 121.

[0054] Optionally, the second horizontal plate 12 is also provided with a second through groove 122 communicating with the first through groove 111. That is, the second horizontal plate 12 is provided with a plurality of second through grooves 122, which are arranged at intervals along the length of the second horizontal plate 12. The second through grooves 122 are aligned with the first through grooves 111 one by one, and the second through grooves 122 are also open in the direction facing the first horizontal plate 11.

[0055] Optionally, the first side plate 13 is provided with a number of heat dissipation holes 131.

[0056] In use, the first horizontal plate 11 and the second horizontal plate 12 are connected by the cooperation of the first plug-in part 112 and the first slot 121, so that the two first side plates 13 can be relatively close or far apart, thereby making the width of the first cable tray 1 adjustable. During use, the size of the cable tray structure can be quickly adjusted according to the need for increased cable laying, improving laying efficiency. After the first plug-in part 112 is inserted into the first slot 121, it can be fixed by the existing locking structure.

[0057] Example 2

[0058] Based on Embodiment 1, in this embodiment, the first cable tray 1 is further provided with multiple sets of first guide structures. The first guide structure includes a first slide rail 113 formed on the first insertion part 112 and a first mounting post 14 provided on the second horizontal plate 12 and matching the first slide rail. By guiding through the guide structure, the accuracy and stability of the second horizontal plate 12 and the first horizontal plate 11 during insertion can be ensured.

[0059] Specifically, the first slide rail 113 is formed on the first insertion part 112, that is, the first insertion part 112 on both sides of the first through groove 111 is provided with a first slide rail 113, and multiple first slide rails 113 are arranged in parallel. The first mounting post 14 is connected to the second horizontal plate 12. The number of first mounting posts 14 is the same as the number of first slide rails 113, and the first mounting posts 14 are slidably connected in the first slide rails 113. At the same time, the top of the first mounting post 14 extends above the first slide rail 113. In use, by adjusting the sliding of the first mounting post 14 in the first slide rail 113, the second horizontal plate 12 is pulled apart (the first side plate 13 on the second horizontal plate 12 moves away from the first side plate on the first horizontal plate 11) or pushed towards the first horizontal plate 11 (the first side plate 13 on the second horizontal plate 12 moves closer to the first side plate on the first horizontal plate 11), thereby realizing the adjustment of the width of the first cable tray 1. Once adjusted to the desired position, the locking structure can limit the first mounting post 14 or the second horizontal plate 12 to prevent the second horizontal plate 12 from sliding relative to the first horizontal plate 11. The addition of the first mounting post 14 facilitates the operation of the second horizontal plate 12, while the first mounting post 14, guided by the first slide rail 113, ensures accuracy and stability during insertion.

[0060] Optionally, the first mounting post 14 extends to the upper end of the first slide rail 113 and is connected to a connecting plate 141, which facilitates the operation of the first mounting post 14.

[0061] In one implementation scenario, the locking structure can be a locking nut that threads with the first mounting post 14. For example, the lower end of the first mounting post 14 extends below the first slide rail 113. When the first mounting post 14 slides to a designated position, the locking nut can be used to restrict the movement of the first mounting post 14, thereby preventing the second horizontal plate from sliding relative to the first horizontal plate. In other embodiments, after the first mounting post 14 moves the second horizontal plate to the designated position, it can also be fixed using other existing locking structures. These locking structures include, but are not limited to: a spring latch (set on the second horizontal plate and fixed by engaging with the insertion part), a fixing bolt (a screw hole is provided on the first slot 121; during fixing, the fixing bolt passes through the screw hole and abuts against the first insertion part), or any other structure that can prevent the second horizontal plate from sliding relative to the first horizontal plate.

[0062] Example 3

[0063] This utility model application provides a cable tray structure, based on embodiment 1 or embodiment 2, such as... Figures 5-8 As shown, the cable tray structure also includes a second cable tray 2, which is located outside the first cable tray 1 and is slidably connected to the first cable tray 1.

[0064] The second cable tray 2 includes a third horizontal plate 21, a fourth horizontal plate 22, and two second side plates 23 fixed to one side of the third horizontal plate 21 and the fourth horizontal plate 22. The two second side plates 23 are symmetrically arranged, such that the third horizontal plate 21 and the fourth horizontal plate 22 are both located between the two second side plates 23. The third horizontal plate 21 and the fourth horizontal plate 22 are slidably engaged by a pull-in structure, thereby changing the distance between the two second side plates 23 to achieve adjustable width of the cable tray structure.

[0065] In this embodiment, the cable tray structure also includes a first locking device. In the initial state, the first cable tray 1 is located inside the second cable tray 2. When it is necessary to adjust the overall length of the cable tray structure, the first cable tray 1 can be pulled out from the second cable tray 2, thereby adjusting the overall length of the cable tray structure. After the first cable tray 1 is pulled out to the designated position, the first locking device can lock and fix the adjusted first cable tray and the second cable tray.

[0066] In one embodiment, the first locking device includes a first latch 3 movably mounted on the second side plate 23, and a first hook 15 disposed on the first side plate 13 and cooperating with the first latch 3. In use, since the first cable tray 1 is slidably connected within the second cable tray 2, the first cable tray 1 can be pulled out towards one end of the second cable tray 2, thereby achieving length adjustment of the cable tray structure. (Reference) Figure 8 As shown in the diagram (assembly diagram of the first side plate 13 and the second side plate 23 after the first cable tray 1 is pulled out), after the first cable tray 1 is pulled out (not completely pulled out), the first latch 3 and the first hook 15 on the outer wall of the second side plate 23 are fastened together to fix the first cable tray 1 and the second cable tray 2, thereby extending the originally overlapping first cable tray 1 and the second cable tray 2 to their maximum length, thus increasing the overall length of the cable tray. At the same time, the width of the first cable tray 1 and the second cable tray 2 can be adjusted as needed to achieve the maximum volume of the cable tray structure. If the length of the above-mentioned assembled cable tray structure is insufficient, a first latch 3 can be set at the other end of the second side plate 23, so that the first latch is fastened to the other cable tray structures to extend the overall length of the cable tray. For example, the outer walls of both ends of the first side plate 13 of the cable tray structure are equipped with first hooks 15, and the outer walls of both ends of the second side plate 23 are equipped with first latches 3. The first latch 3 and the second side plate 23 are detachably connected. When needed, the first latch can be installed on the second side plate. The first latch 3 adopts existing technology, such as spring latch, buckle, etc.

[0067] Optionally, the inner wall of the second side plate 23 is also provided with a receiving groove 231 that matches the first hook 15, so that the first hook 15 can move within the receiving groove 231 to maintain the smooth extraction of the first cable tray 1 from the second cable tray 2.

[0068] In one embodiment, limit blocks 16 are fixed to the outer sides of the two first side plates 13 of the first cable tray 1, and the inner walls of the two second side plates 23 are provided with sliding grooves 232 that match the limit blocks 16. A sealing block is provided at the outlet of the sliding grooves 232 to prevent the first cable tray 1 from being completely pulled out and to prevent the first cable tray 1 from being completely separated from the second cable tray 2. For use, refer to... Figure 8 As shown in the diagram (assembly schematic of the first side plate 13 and the second side plate 23 after the first cable tray 1 is pulled out), when the first cable tray 1 is pulled out from inside the second cable tray 2 until the limiting block 16 contacts the sealing block, the latches movably installed on the outer walls at both ends of the second side plate 23 can engage with the first hook to achieve assembly and fixation between the first cable tray 1 and the second cable tray 2. Optionally, a through hole is provided on the side wall of the second cable tray 2 near the sealing block. When the first cable tray 1 is pulled out from inside the second cable tray 2 until the limiting block 16 contacts the sealing block, the limiting block 16 is located within the through hole, meaning that the limiting block 16 can be observed through the through hole.

[0069] In another embodiment, a slider (not shown in the figure) may be provided on the outer wall of the first side plate 13, and a sliding groove is provided on the inner wall of the second side plate 23 corresponding to the position of the slider to slide and connect with the slider. The first cable tray 1 achieves sliding connection with the second cable tray through the cooperation of the slider and the sliding groove. Sealing blocks are provided at both ends of the sliding groove to prevent the first cable tray 1 from being completely pulled out.

[0070] In one embodiment, the structure and connection method (pull-in and pull-out mating method) of the third horizontal plate 21 and the fourth horizontal plate 22 are basically the same as the arrangement of the first horizontal plate 11 and the second horizontal plate 12.

[0071] Specifically, the third horizontal plate 21 is also provided with multiple third through slots, which are spaced apart along the extension direction of the third horizontal plate 21, so that a second insertion part is formed between each two adjacent third through slots. The third through slots are arranged vertically and vertically, and are open in the direction facing the fourth horizontal plate 22. The fourth horizontal plate 22 is provided with second slots that match the second insertion parts, that is: the fourth horizontal plate 22 has multiple second slots, the positions of the multiple second slots correspond one-to-one with the positions of the multiple second insertion parts, and the second insertion parts can be movably inserted into the second slots, so that the second insertion parts and the second slots form the aforementioned pull-in structure.

[0072] Optionally, the fourth horizontal plate 22 is also provided with a fourth through groove that communicates with the third through groove. The fourth through groove is aligned with the third through groove, and the fourth through groove is also open in the direction of the third horizontal plate 21.

[0073] Optionally, the second side plate 23 is also provided with several heat dissipation holes 131. When the first cable tray is not pulled apart, the heat dissipation holes 131 on the first side plate 13 and the second side plate 23 are aligned one by one.

[0074] In use, the third horizontal plate 21 and the fourth horizontal plate 22 are connected by the cooperation of the second plug and the second slot, so that the two second side plates 23 can be relatively close or far apart, thereby making the width of the second cable tray 2 adjustable.

[0075] In one embodiment, the second cable tray 2 is also provided with multiple sets of second guide structures. The second guide structure includes a second slide rail formed on the second insertion portion and a second mounting post provided on the fourth horizontal plate 22 and matching the second slide rail. The arrangement of the second mounting post is basically the same as that of the first mounting post in embodiment 2, and will not be described again here.

[0076] When the width of the cable tray structure needs to be adjusted, the width of the first cable tray 1 and the second cable tray 2 can be adjusted. Adjusting the width of the second cable tray 2: By adjusting the sliding of the second mounting post within the second slide rail, the fourth horizontal plate 22 is pulled apart (the fourth horizontal plate 22 moves to the right, and the two second side plates 23 move away from each other) or pushed towards the third horizontal plate 21 (the fourth horizontal plate 22 moves to the left, and the two second side plates 23 move closer together), thus adjusting the width of the first cable tray 1. Adjusting the width of the first cable tray 1: By adjusting the sliding of the first mounting post 14 within the first slide rail 113, the second horizontal plate 12 is pulled apart (the second horizontal plate 12 moves to the right, and the two first side plates 13 move away from each other) or pushed towards the first horizontal plate 11 (the second horizontal plate 12 moves to the left, and the two first side plates 13 move closer together), thus adjusting the width of the first cable tray 1. After adjustment to the desired position, the first mounting post 14 and the second mounting post can be limited by the locking structure to fix the mounting posts, thereby preventing the horizontal plates from sliding.

[0077] Example 4

[0078] Traditional cable tray covers are typically large, making them inconvenient to fix and move, which increases construction difficulty and cost.

[0079] like Figure 9 As shown in the figure, this utility model application provides a cable tray structure to solve the above-mentioned technical problems. The cable tray structure includes a cover 4 movably disposed on the cable tray.

[0080] The cover component 4 includes a first top plate 41 and a second top plate 42 that are hinged together. The first top plate 41 includes a horizontal portion 411 and a vertical portion 412 that are integrally formed, and the horizontal portion 411 and the vertical portion 412 form an "L" shape. The structure of the second top plate 42 is the same as that of the first top plate 41, that is, the second top plate 42 also includes a horizontal portion and a vertical portion. During assembly, the vertical portion of the second top plate 42 is hinged to one side of the outer wall of the cable tray, and one side of the horizontal portion is hinged to one side of the horizontal portion of the first top plate 41. The vertical portion of the first top plate 41 is detachably connected to the other side wall of the cable tray through a second locking device 5.

[0081] In one implementation scenario, the second locking device 5 includes a second hook 51 and a cooperating second latch 52. The second hook 51 is disposed on the vertical portion 412 of the first top plate 41 or on the outer wall of the cable tray, and correspondingly, the second latch 52 is disposed on the outer wall of the cable tray or the vertical portion 412. For example, the vertical portion 412 of the first top plate 41 is provided with the second hook 51, and the outer wall of the cable tray is movably mounted with the second latch 52 that matches the second hook 51, thereby achieving the assembly and fixation between the cover 4 and the cable tray through the engagement of the second latch 52 and the second hook 51.

[0082] Optionally, the horizontal portion 411 of the first top plate 41 and the horizontal portion of the second top plate 42 are hinged together by a hinge 6.

[0083] Optionally, the vertical portion of the second top plate 42 is also connected to the side wall of the cable tray via hinge 6.

[0084] Optionally, the cover body 4 can be made of lightweight materials (such as aluminum alloy) to reduce weight and facilitate handling.

[0085] The cable tray connected to the cover 4 can be the first cable tray 1 described in Embodiment 1 or 2, or the second cable tray 2 described in Embodiment 3. In use, a cover 4 of suitable size is selected and assembled onto the second cable tray 2 / first cable tray 1 to protect the cables laid inside the cable tray. When cable maintenance is required, the second latch 52 is opened, the cover 4 is folded, and the cover 4 is turned to one side. This increases the convenience of maintenance and effectively solves the problems of cumbersome installation and difficult handling of traditional cable trays. When using the cable tray structure described in Embodiment 3, when the first cable tray 1 is pulled out from the second cable tray 2, a suitable cover 4 is assembled onto the first cable tray 1 and the second cable tray 2 respectively. The two top plates are connected by hinges 6 to form a foldable structure, allowing for quick unfolding and folding during use. After the cover is unfolded, it is fixed by the second locking device 5 to ensure its stability.

[0086] A method of using a cable tray structure:

[0087] First, the first cable tray 1 is pulled out from inside the second cable tray 2, and the assembly and fixation between the first cable tray 1 and the second cable tray 2 are achieved by the engagement of the first locking buckle 3 and the first hook 15. Then, cables are laid inside the cable tray structure, and then the cover piece 4 is placed on the second cable tray 2 and the first cable tray 1. The cover piece 4 on the second cable tray 2 can be pre-assembled, and the cover piece 4 can be assembled on the first cable tray 1 first and then placed on top of the first cable tray 1 to complete the assembly of the cable tray structure.

[0088] When more cables need to be laid, after the first cable tray 1 and the second cable tray 2 are assembled and fixed, remove the locking structures (locking nuts) one by one, pull open the second horizontal plate 12 and the fourth horizontal plate 22 to expand the overall width of the cable tray, and then tighten the locking structures (locking nuts) one by one. That is, the overall width of the cable tray is widened first in the above way before the cables are laid.

[0089] When the cables inside the cable tray structure need to be inspected, the first latch between the cover and the cable tray should be released in sequence, the cover should be folded and flipped to one side.

[0090] This utility model relates to a pull-out cable tray and a folding cover, which effectively solves the problems of cumbersome installation and difficult handling of traditional cable trays and covers. The pull-out connection method reduces the use of bolts and simplifies the installation process; the folding cover design improves the convenience of handling and fixing; it not only improves construction efficiency but also reduces construction difficulty and cost, and has broad application prospects.

[0091] It should be noted that the specific installation positions of the components in the accompanying drawings of this utility model are schematic, and the size (length, width, thickness, etc.) of the components in each drawing are also schematic. They are only used to express the concept of this technical solution and do not involve the limitation of the specific position and size in the actual embodiment.

[0092] Any aspects not described in detail in this embodiment are techniques known in the art.

[0093] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
