[0034] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0035] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly and specifically defined.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0038] like Figures 1 to 5 As shown, in some embodiments, a cable tray includes a main body 100 and a cover plate 200. The top of the main body 100 is provided with a first folded edge 110, which is positioned opposite to the bottom of the main body 100. A first fastening member 120 protrudes from the surface of the first folded edge 110. The cover plate 200 covers the top of the main body 100, and a second folded edge 210 extends from the cover plate 200 toward the main body 100. The second folded edge 210 has a notch 220, and a second fastening member 230 extends from the side wall of the notch 220, engaging with the first fastening member 120. The assembly of the main body 100 and the cover plate 200 is achieved by engaging the second fastening member 230 with the first fastening member 120. This assembly process eliminates the need for assembly tools, enabling rapid assembly and improving assembly efficiency. Furthermore, the assembly does not require bolts and nuts, reducing assembly costs.

[0039] Specifically, the cable tray can be a ladder-type cable tray.

[0040] like Figure 5 As shown, in some embodiments, the upper surface 231 of the second fastener 230 abuts against the side wall of the top of the first fastener 120, and the upper surface 231 of the second fastener 230 is inclined downward along the extending direction of the second fastener 230. The upper surface 231 of the second fastener 230 abuts against the side wall of the top of the first fastener 120, forming a stable mechanical contact structure. This structure provides support to the cover plate 200 in the vertical direction, limiting the displacement of the cover plate 200 relative to the main body 100 in the vertical direction. During installation, the downwardly inclined upper surface 231 can play a guiding and auxiliary positioning role. When the construction personnel install the cover plate 200 onto the main body 100, the second fastener 230 can be smoothly inserted into the first fastener 120 along the inclined surface, and as the insertion process proceeds, it will automatically adjust to the optimal connection position, reducing the alignment difficulty and adjustment time during installation and improving installation efficiency.

[0041] like Figure 6As shown, in some embodiments, the first fastener 120 includes a first part 121, a second part 122, and a third part 123. One end of the first part 121 and one end of the second part 122 are both connected to the surface of the first folded edge 110. The other end of the first part 121 away from the first folded edge 110 is connected to the third part 123. The other end of the second part 122 away from the first folded edge 110 is connected to the third part 123. The first part 121 and the second part 122 are disposed opposite to each other, and the top of the first part 121 is inclined toward the second part 122 relative to the bottom of the first part 121, and the top of the second part 122 is inclined toward the first part 121 relative to the bottom of the second part 122.

[0042] Specifically, the first part 121, the second part 122, and the third part 123 form a "U"-shaped structure.

[0043] like Figure 6 As shown, in some embodiments, the first folded edge 110 has a hollow portion 130. The hollow portion 130 is located between the first portion 121 and the second portion 122, and below the third portion 123. By providing the hollow portion 130, the weight of the first folded edge 110 can be reduced, thereby reducing the overall load on the cable tray. A lighter cable tray is easier to transport and install, reducing construction difficulty and labor intensity, and also reducing the load-bearing pressure on the building structure, which is beneficial to improving the safety of the building. In addition, the hollow portion 130 can reduce the amount of material used, thereby reducing the production cost of the cable tray.

[0044] In some embodiments, multiple first fasteners 120 and multiple second fasteners 230 are provided, with each of the multiple first fasteners 120 and multiple second fasteners 230 corresponding one-to-one. That is, there are multiple mutually cooperating fastening points between the cover plate 200 and the main body 100. The cooperation between the multiple first fasteners 120 and the multiple second fasteners 230 can increase the stability of the connection between the cover plate 200 and the main body 100. Compared with a single connection, multiple fastening points can distribute the force. When the cable tray is subjected to external force, each fastening point can bear a part of the force, thereby effectively reducing the stress borne by a single fastener, reducing the risk of fastener loosening or damage, ensuring that the cover plate 200 is always tightly fixed to the main body 100, and better protecting the cable components inside the cable tray.

[0045] In some embodiments, the ratio of the spacing between two adjacent first fasteners 120 to the length of the main body 100 is 1 / 4 to 3 / 4. The ratio of the spacing between two adjacent second fasteners 230 to the length of the cover plate 200 is 1 / 4 to 3 / 4. This ratio range is set based on a balance between the connection stability of the cover plate 200 and the main body 100 and the manufacturing cost. If the spacing between the first fasteners 120 and the second fasteners 230 is too close, it will increase the number of first fasteners 120 and second fasteners 230 used, thereby increasing the cost of raw materials and processing. If the spacing between the first fasteners 120 and the second fasteners 230 is too far apart, it may not be possible to provide enough connection points to ensure the connection stability between the cover plate 200 and the main body 100. This ratio range can meet the connection stability requirements of the cover plate 200 and the main body 100, and can also avoid unnecessary cost increases caused by excessively dense first fasteners 120 and second fasteners 230. By reasonably controlling the number of the first fastener 120 and the second fastener 230, the raw material procurement cost and processing cost of the cable tray can be effectively reduced during the production process.

[0046] like Figure 7 As shown, in some embodiments, two first folded edges 110 are provided. The two first folded edges 110 are located on both sides of the main body 100. Two second folded edges 210 are provided, located on both sides of the cover plate 200. The combination of the first folded edges 110 on both sides of the main body 100, the second folded edges 210 on both sides of the cover plate 200, the first buckles corresponding to the first folded edges 110, and the second buckles corresponding to the second folded edges 210 forms a more robust connection system. Compared to single-sided or single-group folded edge and buckle connections, the double-sided design can better resist external force interference from different directions. For example, when the cable tray is subjected to lateral impact or wind force, the connection structure on both sides can share the force, reduce local stress concentration, effectively prevent relative displacement or detachment between the cover plate 200 and the main body 100, and ensure the integrity of the cable tray and the safety of the internal cables. During installation, the structure of the first fastener 120 and the second fastener 230 on both sides provides more convenient operating conditions for construction personnel, allowing for simultaneous installation from both sides, improving installation efficiency. Furthermore, in subsequent maintenance and repair work, it is easier to inspect, adjust, and repair the connection parts, reducing maintenance difficulty and workload.

[0047] like Figure 3As shown, in some embodiments, the main body 100 includes a first side plate 140, a second side plate 150, and a support member 160. The first side plate 140 and the second side plate 150 are disposed opposite to each other. One end of the support member 160 is connected to the first side plate 140, and the other end of the support member 160 is connected to the second side plate 150. A protrusion is provided on the support member 160. The support member 160, the first side plate 140, and the second side plate 150 form a receiving space for accommodating cables. The protrusion can increase the area of ​​the support member 160, improve the heat dissipation capacity of the support member 160, and achieve an energy-saving effect.

[0048] It should be noted that the first side plate 140 and the second side plate 150 have the same structure. During manufacturing, the same molds, processing techniques, and production processes can be used to manufacture both the first side plate 140 and the second side plate 150. For example, in a stamping process, only one set of molds is needed to produce both the first side plate 140 and the second side plate 150, eliminating the need to design and manufacture separate molds for side plates with different structures, significantly reducing mold development costs and manufacturing cycles. The identical structure of the first side plate 140 and the second side plate 150 gives the cable tray an overall structural symmetry. A symmetrical structure can distribute stress more evenly under load, reducing localized stress concentrations caused by structural asymmetry.

[0049] Specifically, the first side plate 140 and the second side plate 150 can be rectangular.

[0050] Specifically, the load-bearing member 160 can be a plate-like structure.

[0051] In some embodiments, the cable tray includes a first connecting plate with a first mounting portion. The first connecting plate is connected to one end of a first side plate 140, and the other end of the first side plate 140 has a second mounting portion. That is, the first mounting portion of one first connecting plate can be mounted on the second mounting portion of another first connecting plate, thereby enabling the installation of two cable trays. The cable tray also includes a second connecting plate with a third mounting portion. The second connecting plate is connected to one end of a second side plate 150, and the other end of the second side plate 150 has a fourth mounting portion. That is, the third mounting portion of one second connecting plate can be mounted on the fourth mounting portion of another second connecting plate, thereby enabling the installation of two cable trays. Specifically, the cable tray can be a socket-type structure.

[0052] The first connecting plate extends relative to the first side plate 140 in a direction away from the second side plate 150 and then extends along the length of the first side plate 140. The second connecting plate extends relative to the second side plate 150 in a direction away from the first side plate 140 and then extends along the length of the second side plate 150. The first connecting plate extends relative to the first side plate 140 in a direction close to the second side plate 150 and then extends along the length of the first side plate 140. The second connecting plate extends relative to the second side plate 150 in a direction close to the first side plate 140 and then extends along the length of the second side plate 150.

[0053] In some embodiments, the first side plate 140, the second side plate 150, and the support member 160 are integrally formed structures.

[0054] In other embodiments, both the first side plate 140 and the second side plate 150 are welded to the carrier 160.

[0055] In some embodiments, the side of the first side plate 140 away from the second side plate 150 may be provided with reinforcing ribs to enhance the strength of the first side plate 140. The side of the second side plate 150 away from the first side plate 140 may also be provided with reinforcing ribs to enhance the strength of the second side plate 150.

[0056] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
