Construction workers only need to align the elastic clips on the connecting strips with the vertical beams of the cable tray unit and gently press them in to complete the connection, eliminating the need for complex cutting and welding operations. This rapid connection method not only reduces construction time but also reduces quality problems caused by on-site processing, improving the overall quality of construction.

The curved outer and inner connecting strips are integrally stamped, directly forming the elastic fasteners on the connecting strips, reducing additional processing steps and lowering production costs. Moreover, the curved outer and inner connecting strips firmly fix the outer and inner vertical beams of the cable tray unit using first and second elastic fasteners, respectively, forming a stable connection structure.

[0034] In summary, this technical solution effectively solves the technical problems of high production cost and complex on-site construction of traditional curved cable trays by using arc-shaped connecting strips and elastic fasteners in combination. It provides a low-cost, easy-to-manufacture, and structurally stable cable mesh cable tray system and manufacturing method. Attached Figure Description

[0046] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0047] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0048] like Figures 1 to 4 As shown, the present invention provides a cable mesh tray system 100, which aims to solve the problems of high manufacturing cost and complex on-site construction of traditional turning cable trays. The system includes a turning cable tray 101 and two straight mesh cable trays 102. The straight mesh cable trays 102 are respectively connected to both sides of the turning cable tray 101 through interfaces 103, thereby realizing the connection of smooth turning and straight laying of cables.

[0049] Specifically, the turning cable tray 101 includes multiple cable tray units 10 arranged in a divergent pattern. Each cable tray unit 10 includes a bottom unit 13, a first side unit 11', and a second side unit 12', with the first side unit 11' located at the inner end and the second side unit 12' located at the outer end. The inner ends of the multiple cable tray units 10 are close to each other and form an inner arc shape, while the outer ends of the multiple cable tray units 10 are separated from each other and form an outer arc shape. In other words, the turning cable tray 101 is composed of multiple cable tray units 10 arranged in a divergent pattern, with the inner ends of these cable tray units 10 close to each other to form an inner arc shape and the outer ends separated from each other to form an outer arc shape, thus naturally forming a turning structure.

[0050] like Figure 7As shown, each cable tray unit 10 includes two parallel U-shaped weft wires 11 and multiple radial wire units 12, with the radial wire units 12 connected in parallel between the two U-shaped weft wires 11. The U-shaped weft wires 11 consist of an outer vertical beam a2, a bottom beam a3, and an inner vertical beam a1, ensuring the strength of the cable tray and providing stable support for cable laying.

[0051] To achieve a reliable connection between the curved cable tray 101 and the straight grid cable tray 102, this invention employs a unique connection method. The outer edge of the curved cable tray 101 is connected to the outer edges of the two straight grid cable trays 102 via an arc-shaped outer connecting strip 20; the inner edge of the curved cable tray 101 is connected to the inner edges of the two straight grid cable trays 102 via an arc-shaped inner connecting strip 30. The arc-shaped outer connecting strip 20 and the arc-shaped inner connecting strip 30 are used to connect the outer and inner edges of the curved cable tray 101 to the corresponding edges of the straight grid cable trays 102, respectively. This arc-shaped design naturally conforms to the curved shape of the cable tray, ensuring a more uniform stress distribution at the connection points and avoiding structural damage caused by stress concentration.

[0052] Among them, such as Figure 9 and Figure 10 As shown, the inner side of the arc-shaped outer connecting strip 20 is provided with a plurality of integrally stamped first elastic fasteners 21. The first elastic fasteners 21 in the middle part fasten the outer vertical beams a2 of each cable tray unit 10, and the first elastic fasteners 21 at both ends fasten the outer vertical beams a2 of the straight grid cable tray 102.

[0053] In addition, such as Figure 4 As shown, the inner side of the arc-shaped inner connecting strip 30 is provided with multiple integrally stamped second elastic fasteners 31. The second elastic fasteners 31 in the middle part fasten the inner vertical beams a1 of each cable tray unit 10, and the second elastic fasteners 31 at both ends fasten the inner vertical beams a1 of the straight grid cable tray 102.

[0054] like Figure 5 As shown, the inner sides of the arc-shaped outer connecting strip 20 and the arc-shaped inner connecting strip 30 are respectively provided with multiple integrally stamped first elastic fasteners 21 and second elastic fasteners 31. These fasteners firmly fasten the outer vertical beam a2 and inner vertical beam a1 of the cable tray unit through elastic deformation, ensuring a tight connection between cable tray units and between cable tray units and straight cable trays, effectively preventing loosening and displacement.

[0055] Through this innovative structural design and connection method, the cable mesh tray system 100 of the present invention reduces production costs, simplifies the construction process, and improves construction efficiency while ensuring the turning function. It is particularly suitable for various scenarios that require cable turning, such as data centers, communication base stations, and industrial plants.

[0056] More specifically, such as Figure 5, Figure 9 and Figure 10 As shown, the first elastic fastener 21 is a metal sheet v stamped from the arc-shaped outer connecting strip 20, with a hole 22 formed in the arc-shaped outer connecting strip 20. The metal sheet v has a root v1 and a free end v2; the metal sheet v is bent at the root v1 to form an extruded part v3 that wraps around the outer vertical beam. The stamping process ensures the material continuity and integrity of the fastener, avoiding structural weaknesses that may be caused by welding or splicing.

[0057] Similarly, as Figure 6 As shown, the second elastic buckle 31 is also a metal sheet v formed from the arc-shaped inner connecting strip 30. The metal sheet v has a root v1 and a free end v2. The metal sheet v is bent at the root v1 to form a compression part v3 that wraps around the outer vertical beam.

[0058] It should be noted that the metal sheet v is bent at the root v1 to form an extruded part v3, which can tightly wrap around the outer vertical beam a2 or the inner vertical beam a1. This design not only increases the contact area at the connection point, but also further enhances the bonding strength between the cable tray unit and the connecting strip through the pressure generated by elastic deformation, ensuring stability when carrying cables.

[0059] Through the specific structure of the first elastic fastener 21 and the second elastic fastener 31, the present invention not only significantly enhances the connection strength and stability between the curved cable tray 101 and the straight grid cable tray 102, but also improves the convenience and efficiency of installation and reduces production and maintenance costs.

[0060] The two first elastic fasteners 21 corresponding to the outer vertical beam a2 of the same cable tray unit 10 extend in opposite directions on the arc-shaped outer connecting strip 20; and the two first elastic fasteners 21 are at the same height on the arc-shaped outer connecting strip 20.

[0061] This technique allows the two fasteners to apply clamping force to the vertical beam from different directions, creating a "clamping" effect that significantly enhances the friction and clamping strength between the fasteners and the vertical beam, thereby improving the stability of the connection. Furthermore, the two first elastic fasteners 21 are at the same height on the arc-shaped outer connecting strip 20, ensuring uniform contact between the fasteners and the outer vertical beam a2.

[0062] Furthermore, both outer ends of the arc-shaped outer connecting strip 20 are equipped with connecting hooks 24 that bend laterally towards the outer vertical beam a2, so as to connect with the corresponding outer vertical beam a2 of the straight grid cable tray 102. The presence of the connecting hooks 24 enables the arc-shaped outer connecting strip 20 to form a tight mechanical connection with the outer vertical beam a2 of the straight grid cable tray 102. This laterally bent hook structure provides additional gripping force, ensuring that the connection will not loosen or fall off when subjected to external forces (such as cable tension, vibration, or impact), thereby significantly enhancing the stability of the entire cable tray system.

[0063] In addition, the two second elastic fasteners 31 corresponding to the inner vertical beam a1 of the adjacent cable tray unit 10 extend in opposite directions on the arc-shaped inner connecting strip 30; similarly, the two second elastic fasteners 31 extend in opposite directions, which can apply clamping force to the inner vertical beam a1 from different angles, forming a "clamping" effect; significantly enhancing the friction and clamping strength between the fasteners and the inner vertical beam a1, ensuring that it will not loosen when carrying cables.

[0064] The two second elastic fasteners 31 are staggered in height on the arc-shaped inner connecting strip 30. This staggered design allows the fasteners to apply a uniform clamping force to the inner vertical beam a1 at different positions, further enhancing the stability of the connection.

[0065] Moreover, the design of opposite extension direction and height misalignment allows the fastener to better adapt to external forces in different directions, effectively dispersing and absorbing both vertical and horizontal forces.

[0066] Both outer ends of the arc-shaped inner connecting strip 30 are equipped with connecting hooks 34 that bend laterally towards the inner vertical beam a1, so as to connect with the corresponding inner vertical beam a1 of the straight grid cable tray 102. Similarly, the connecting hooks 34, through their lateral bending design, can tightly and mechanically lock the curved cable tray 101 to the inner vertical beam a1 of the straight grid cable tray 102. This locking method significantly enhances the stability of the connection, ensuring that it will not loosen or fall off when carrying cables.

[0067] Preferably, the first side unit 11' of the cable tray unit 10 has two radial units 12; the arc-shaped outer connecting strip 20 is placed between the two radial units 12; the second side unit 12' of the cable tray unit 10 has two warp units 12, and the arc-shaped inner connecting strip 30 is placed between the two warp units 12. The two radial units 12 on the first side unit 11' and the second side unit 12' respectively provide a more stable support structure for the cable tray unit 10. This double-support design can effectively distribute and bear the weight of the cable, reducing deformation or bending that may occur due to a single radial unit.
