[0002] In fields such as power systems, communication networks, and industrial automation, cable trays, as the core supporting components for cable laying, have expanded their application scenarios from traditional power distribution trunk lines within buildings to complex environments such as urban underground utility tunnels, large data center computer rooms, new energy power plants, and intelligent manufacturing workshops. In high-rise buildings, cable trays need to support a large number of vertically laid power cables, placing stringent requirements on their load-bearing stability and vibration resistance. In underground pipeline scenarios, they need to withstand the effects of moisture, corrosive gases, and soil pressure over long periods. In locations such as data centers, the dense network of communication cables requires cable trays to possess efficient cabling organization and convenient maintenance access.

[0003] Traditional cable trays are often connected using bolts, which requires tools to tighten each point, resulting in low installation efficiency and instability at the joints due to loose bolts. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides a splicing cable tray, which solves the technical problems of traditional cable trays in the prior art, which mostly use bolt connections for connection, require tools to tighten point by point during connection, resulting in low installation efficiency, and the splicing joints are prone to insufficient stability due to loose bolts.

[0005] According to one aspect, at least one embodiment of the present invention provides a splicing cable tray, comprising: a cable tray body, the cable tray body being used to carry cables, and slide rails symmetrically provided on both sides of the inner bottom end of the cable tray body; A docking assembly is installed at the upper end of the cable tray body and is used to fix the front and rear splicing of two independent cable tray bodies. Side connection components are installed on both sides of the inner side of the cable tray body, and the side connection components include movable side plates.

[0006] For example, in a splicing cable tray provided by at least one embodiment of the present invention, the docking assembly includes a first limiting frame, a second limiting frame and a plug-in block. The second limiting frame is fixedly connected to the upper and lower surfaces of the right end of the cable tray body. The second limiting frame is symmetrically installed at the middle of the upper and lower surfaces of the cable tray body. The first limiting frame is fixedly connected to the upper and lower surfaces of the left end of the cable tray body. The plug-in block is movably installed inside the first limiting frame. The right end of the plug-in block is fixedly connected to a limiting block, and the left end of the plug-in block is fixedly connected to a movable locking block. The movable card blocks are symmetrically distributed above the plug-in block.

[0007] For example, in a splicing cable tray provided in at least one embodiment of the present invention, the outer diameter of the plug block matches the inner diameter of the first limiting frame, and the inner diameter of the second limiting frame is the same as the inner diameter of the first limiting frame.

[0008] For example, in a splicing cable tray provided in at least one embodiment of the present invention, a connector is fixedly connected to the left end of the main body of the cable tray, and openings for mating are provided on both sides of the main body of the cable tray, wherein the outer diameter of the connector matches the inner diameter of the opening.

[0009] For example, in a splicing cable tray provided in at least one embodiment of the present invention, positioning holes are provided on both sides of the main body of the cable tray, and lifting wings are fixedly connected to the bottom of both sides of the main body of the cable tray.

[0010] For example, in a splicing cable tray provided in at least one embodiment of the present invention, the outer diameter of the movable side plate matches the inner diameter of the slide rail, and the movable side plate is slidably connected to the main body of the cable tray through the slide rail.

[0011] For example, in a splicing cable tray provided in at least one embodiment of the present invention, the surface of the movable side plate is symmetrically provided with grooves, and both ends of the movable side plate are fixedly connected with self-locking buttons.

[0012] For example, in a splicing cable tray provided in at least one embodiment of the present invention, the self-locking button includes a housing, a spring is fixedly connected inside the housing, a button core is fixedly connected to the top of the spring, and the button core is movably connected to the housing through the spring.

[0013] The beneficial effects of this utility model are as follows: (1) In this utility model, the docking component achieves rapid splicing of the cable tray body through the cooperation of the first limiting frame, the second limiting frame and the plug-in block. No external tools are needed, and the operation can be completed by manual pressing and pushing, which greatly improves the installation efficiency. The size matching design of the plug-in block and the limiting frame ensures the tightness of the splice and avoids loosening. The setting of the limiting block effectively limits the insertion depth of the plug-in block and prevents the limiting block from shaking during the connection process, which affects the structural stability. The symmetrically distributed movable locking blocks can realize bidirectional locking and fixing of the plug-in block, further enhancing the stability of the splice. Compared with the traditional bolt connection, the splicing strength is increased by more than 30%.

[0014] (2) In this utility model, the movable side plate of the side connection component is slidably connected to the main body of the cable tray through the slide rail, realizing flexible opening and closing. When it is necessary to inspect or add or remove cables, there is no need to disassemble the overall structure. It is only necessary to open the movable side plate to operate, which greatly improves the convenience of inspection and maintenance. The groove design provides operators with a convenient force application point, which facilitates the pulling of the movable side plate. The spring reset structure of the self-locking button allows the movable side plate to automatically engage and fix with the positioning hole after closing, avoiding the sliding of the movable side plate due to vibration and other factors during use, and ensuring the stability of the protection effect. The closed design of the movable side plate can effectively prevent dust and water, protect the cable from the influence of the external environment, and extend the service life of the cable.

[0023] like Figures 1-3 As shown, it illustrates a splicing cable tray in one embodiment of the present invention, including: a cable tray body 1, which is used to carry cables, and slide rails 13 are symmetrically opened on both sides of the bottom of the cable tray body 1. The docking component 2 is installed on the upper end of the cable tray body 1 and is used to fix the front and rear splicing of two independent cable tray bodies 1. Side connection component 3: Both sides of the cable tray body 1 are equipped with side connection components 3, which include movable side plates 31.

[0024] The docking component 2 includes a first limiting frame 21, a second limiting frame 22 and a plug-in block 23. The second limiting frame 22 is fixedly connected to the upper and lower surfaces of the right end of the cable tray body 1. The second limiting frame 22 is symmetrically installed at the middle of the upper and lower surfaces of the cable tray body 1. The first limiting frame 21 is fixedly connected to the upper and lower surfaces of the left end of the cable tray body 1. The plug-in block 23 is movably installed inside the first limiting frame 21. The right end of the plug-in block 23 is fixedly connected to the limiting block 24, and the left end of the plug-in block 23 is fixedly connected to the movable locking block 25. The active card blocks 25 are symmetrically distributed above the plug-in block 23.

[0025] The outer diameter of the plug block 23 matches the inner diameter of the first limiting frame 21, and the inner diameter of the second limiting frame 22 is the same as that of the first limiting frame 21.

[0026] The left end of the cable tray body 1 is fixedly connected to a connector 11. The two sides of the cable tray body 1 are provided with mating openings, and the outer diameter of the connector 11 matches the inner diameter of the opening.

[0027] Positioning holes 12 are provided on both sides of the main body 1 of the cable tray, and lifting wings 14 are fixedly connected to the bottom of both sides of the main body 1 of the cable tray.

[0028] This embodiment provides a splicing cable tray. By setting the docking component 2, it is convenient to splice two independent cable tray bodies 1. In use, firstly, align the connector 11 of the right cable tray body 1 with the cable inlet of the left cable tray body 1 and insert it. Then, push the plug block 23 on the upper part of the right cable tray body 1 into the second limiting frame 22 on the upper part of the left cable tray body 1. When the plug block 23 moves into the second limiting frame 22, the movable locking block 25 enters the interior of the second limiting frame 22 first, and its two ends are limited by the inner wall of the second limiting frame 22. The restrictions will converge. When the movable block 25 completely passes through the second limit frame 22, the restrictions on its two end limit parts will disappear. The limit parts will return to their original position under their own elastic force and lock with the first limit frame 21, thus completing the fixation of the plug-in block 23 and realizing the firm splicing of the two cable tray bodies 1. All docking can be completed by docking the docking components 2 on the upper and lower sides of the cable tray body 1. The setting of the first limit frame 21 and the limit block 24 can prevent the movable block 25 from shifting after locking, increasing the stability of docking. The main body 1 of the cable tray adopts a trough-shaped structure design with a thickness of 3mm at the bottom and on both sides, which can evenly distribute the weight of the cable. The lifting wings 14 are symmetrically distributed on both sides of the bottom of the main body 1 of the cable tray, so that the lifting force is evenly transmitted to the main body 1 of the cable tray, avoiding excessive local stress and deformation.

[0029] The combination of the channel-shaped structure of the main body 1 of the cable tray and the high-quality cold-rolled steel plate significantly improves the overall structural strength and load-bearing capacity, enabling it to support a larger number of cables and resisting deformation over long-term use. The matching design of the connector 11 and the opening achieves accurate initial positioning during splicing, avoiding the misalignment problem that easily occurs in traditional splicing and improving the regularity of the splicing. The lifting wings 14 at the bottom of both sides adopt a folded edge process, which increases the lifting contact area, makes the lifting force distribution more even, reduces the risk of the cable tray tipping over during lifting and use, and improves the safety of installation and use.

[0030] The docking component 2, through the cooperation of the first limiting frame 21, the second limiting frame 22, and the plug-in block 23, enables the rapid splicing of the cable tray body 1. No external tools are required; the operation can be completed simply by manual pressing and pushing, significantly improving installation efficiency. The dimensional fit between the plug-in block 23 and the limiting frame ensures a tight joint and prevents loosening. The limiting block 24 effectively restricts the insertion depth of the plug-in block 23, preventing it from shaking during connection and affecting structural stability. The symmetrically distributed movable locking blocks 25 enable bidirectional clamping and fixing of the plug-in block 23, further enhancing the stability of the joint. Compared to traditional bolt connections, the splicing strength is increased by more than 30%.

[0031] like Figures 1-4 As shown, in some examples, the outer diameter of the movable side plate 31 matches the inner diameter of the slide rail 13, and the movable side plate 31 is slidably connected to the bridge frame body 1 through the slide rail 13.

[0032] The surface of the movable side plate 31 is symmetrically provided with grooves 32, and both ends of the movable side plate 31 are fixedly connected with self-locking buttons 33.

[0033] The self-locking button 33 includes a housing 331, a spring 332 is fixedly connected inside the housing 331, a button core 333 is fixedly connected to the top of the spring 332, and the button core 333 is movably connected to the housing 331 through the spring 332.

[0034] This embodiment provides a splicing cable tray. After the movable side plate 31 is closed via the slide rail 13, it can completely cover the openings on both sides of the cable tray body 1, forming a closed cable laying space. The engagement of the self-locking button 33 with the positioning hole 12 ensures that the movable side plate 31 will not slide on its own during use, effectively preventing dust, moisture and external debris from entering the cable tray and protecting the cables from damage. When it is necessary to inspect the cables, press the button core 333 of the self-locking button 33 to disengage it from the positioning hole 12, and pull the movable side plate 31 along the slide rail 13 through the pull groove 32 to open it, so that the internal cables can be operated. Alternatively, when the cables need to be vertically paralleled or cross-laid, open the movable side plates 31 on both sides of the cable tray body 1, insert the connector 11 of another set of cable tray bodies 1 into the side opening of the first set of cable tray bodies 1, and use the docking assembly 2 to make the two sets of cable tray bodies 1 vertically paralleled, or connect the other set of cable tray bodies 1 to both sides of one set of cable tray bodies 1 to complete the cross-laid wiring.

[0035] The movable side plate 31 of the side connection component 3 is slidably connected to the cable tray body 1 via the slide rail 13, realizing flexible opening and closing. When maintenance or cable addition or removal is required, there is no need to disassemble the overall structure; simply opening the movable side plate 31 is sufficient for operation, greatly improving the convenience of maintenance. The design of the pull groove 32 provides operators with a convenient force application point, facilitating the pulling of the movable side plate 31. The spring reset structure of the self-locking button 33 allows the movable side plate 31 to automatically engage and fix with the positioning hole 12 after closing, preventing the movable side plate 31 from sliding due to vibration or other factors during use, ensuring the stability of the protective effect. The closed design of the movable side plate 31 can effectively prevent dust and water, protect the cable from the influence of the external environment, and extend the service life of the cable.
