Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a lightweight cable tray with a wire clamping mechanism. Background Technology

[0002] Cable trays are an important component of cable laying and management. Proper selection and use of cable trays can effectively ensure the safe and stable operation of cable systems, while also improving the system's aesthetics and ease of maintenance. However, conventional cable trays often suffer from disordered cable stacking. Random entanglement of power and control cables causes electromagnetic interference, and dense stacking leads to localized temperature rises exceeding design standards, resulting in time-consuming troubleshooting.

[0003] To address the aforementioned issues, current technical solutions employ cable clamping mechanisms to hold and secure cables. Some clamping mechanisms utilize discrete, independent clamps, with each clamping unit securing a single cable. However, this approach reduces the space utilization of the cable tray. Other solutions employ integrated clamping structures, which can achieve parallel fixing of multiple cables, but the clamping mechanism itself occupies internal space within the cable tray, limiting the number of cables that can be laid inside. Utility Model Content

[0004] Therefore, it is necessary to provide a lightweight cable tray with a clamping mechanism to address the problem that existing clamping mechanisms limit the number of cables that can be laid in the cable tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightweight cable tray with a clamping mechanism is mainly composed of the tray body and the clamping mechanism.

[0007] The cable clamping mechanism includes a clamping rod and an elastic limiting member; the clamping rod is rectangular and runs through the main body of the cable tray, with its bottom and top ends located below and inside the main body of the cable tray, respectively; the elastic limiting member is disposed between the main body of the cable tray and the bottom of the clamping rod to limit the cable within the rectangular space enclosed by the clamping rod and the main body of the cable tray.

[0008] Furthermore, the elastic limiting element includes a spring; the spring is disposed between the bottom of the cable tray body and the inner bottom end of the clamping rod.

[0009] Furthermore, the elastic limiting component includes a spring and a limiting bolt; the top and bottom sides of the clamping rod extend outwards, and the spring is disposed between the extension portion of the top side of the clamping rod and the inner bottom end of the cable tray body; the outer side wall of the cable tray body extends horizontally outwards towards the clamping rod and is longitudinally threadedly connected to the limiting bolt, and the bottom end of the limiting bolt contacts the extension portion of the bottom side of the clamping rod.

[0010] Furthermore, the inner wall of the clamping rod is bonded with an anti-slip pad.

[0011] Furthermore, the clamping rod consists of a U-shaped bottom rod and a top rod, with the U-shaped bottom rod hinged to one side of the top rod and snapped into place on the other side.

[0012] Furthermore, the top rod surface has multiple rectangular holes longitudinally opened, and the bottom end of the partition plate passes through the rectangular holes and is engaged with the inner bottom end of the cable tray body.

[0013] Furthermore, the top rod surface has an opening, the bottom end of the partition plate passes through the opening and contacts the inner bottom end of the cable tray body, the bottom end of the partition plate extends along the length of the cable tray body and is threaded with a locking bolt, the bottom end of the cable tray body has a sliding hole near the locking bolt, the end of the locking bolt passes through the sliding hole and fits tightly with the outer bottom end of the cable tray body.

[0014] Furthermore, the length of the opening is the same as the length of the sliding hole, and there are two sliding holes, located on the two sides below the opening.

[0015] Furthermore, the top of the partition is flush with the inner top of the cable tray body.

[0016] Furthermore, the longitudinal length of the clamping rod is greater than the longitudinal length of the cable tray body.

[0017] Compared with the prior art, the beneficial effects of this utility model include:

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example 1

[0030] Please see Figure 1 and Figure 2 This embodiment introduces a lightweight cable tray with a clamping mechanism 2, which mainly consists of a cable tray body 1 and a clamping mechanism 2. The cable tray body 1 is formed into a continuous channel structure by high-strength aluminum alloy extrusion molding process, and the thickness gradient of the side wall is controlled within the range of 0.8-1.2mm, which ensures both structural rigidity and lightweighting.

[0031] The cable clamping mechanism 2 mainly consists of a clamping rod 21 and an elastic limiting member 22. The clamping rod 21 adopts a rectangular closed frame structure, consisting of a U-shaped bottom rod 211 and a top rod 212. The U-shaped bottom rod 211 and the top rod 212 are hinged on one side and snapped on the other side. A hole through which the U-shaped bottom rod 211 runs is provided at the bottom of the cable tray body 1. Therefore, the top end of the U-shaped bottom rod 211 enters the interior of the cable tray body 1 through the hole and is hinged to the top rod 212. The bottom end of the U-shaped bottom rod 211 is located below the cable tray body 1, and the cable is located within the rectangular space enclosed by the clamping rod 21 and the cable tray body 1. In this embodiment, the elastic limiting member 22 is a spring 221. The two ends of the spring 221 are respectively anchored in the special slots at the bottom of the cable tray body 1 and the inner bottom end of the clamping rod 21.

[0032] During cable laying, the cable is constrained within a rectangular space enclosed by the inner wall of the clamping rod 21 and the main body 1 of the cable tray. Under the action of the spring 221 and its own weight, the clamping rod 21 moves downwards to contact and limit the cable. The cable can pass through the rectangular space enclosed by the inner wall of the clamping rod 21 and the main body 1 of the cable tray, or it can be moved into the U-shaped bottom rod 211 by flipping the top rod 212. To enhance clamping stability, the inner wall of the clamping rod 21 is equipped with an anti-slip pad, and the surface is decorated with an array of staggered V-shaped grooves to improve anti-slip properties.

[0033] The top rod 212 of the clamping rod 21 has linearly equidistant rectangular holes laser-cut into its surface. The size of the rectangular holes matches the cross-sectional area of ​​the partition 3. The partition 3 is made of thick insulating composite material, and the number of partitions 3 is determined according to the actual space to be divided. After the partition 3 is inserted, its bottom end locks into the positioning groove at the bottom of the cable tray body 1, and its top end is flush with the top surface of the cable tray body 1 to form a continuous support surface. In addition, for the needs of high-current cable laying, aluminum alloy heat dissipation fins can be added to the inside of the clamping rod 21 to reduce the temperature rise by increasing the heat dissipation area.

[0034] In this embodiment, the cable clamping mechanism 2 uses a longitudinal through-type clamping rod 21 to fix the cable. Compared with the traditional transverse clamping mechanism, the longitudinal clamping force is parallel to the cable laying direction, which reduces space occupation. Moreover, the installation process of the clamping mechanism does not require damage to the integrity of the cable tray structure.

[0035] Example 2

[0036] Please see Figure 3-5 This embodiment introduces a lightweight cable tray with a clamping mechanism 2, which is basically the same as the lightweight cable tray with a clamping mechanism 2 introduced in Embodiment 1. The difference is that the elastic limiting member 22 in this embodiment uses a spring 221 and a limiting bolt 222. The top of the clamping rod 21 extends outward and serves as a spring positioning post. A matching spring seat hole is machined at the bottom of the cable tray body 1, and the spring 221 is disposed between the two. The outer wall of the cable tray body 1 extends horizontally and has threaded holes machined longitudinally. The limiting bolt 222 cooperates with the cable tray body 1 to achieve longitudinal fine adjustment. The bottom end of the limiting bolt 222 contacts the extension part of the bottom side of the clamping rod 21. The spring 221 pushes the clamping rod 21 upward. The limiting bolt 222 can limit the upward displacement of the clamping rod 21. After the cable enters the rectangular space enclosed by the clamping rod 21 and the cable tray body 1, rotating the limiting bolt 222 downward can drive the clamping rod 21 downward and compress the spring 221, so that the clamping rod 21 contacts the cable and limits its movement.

[0037] Since the longitudinal length of the clamping rod 21 is greater than the longitudinal length of the cable tray body 1, when the clamping rod 21 is not needed to limit and clamp the cable, the limiting bolt 222 can be rotated and moved upward. After the cable is laid on the cable tray body 1, the clamping rod 21 moves upward under the action of the spring 221 and contacts the top of the cable tray body 1, which serves as a reinforcing rib.

[0038] This embodiment has the same beneficial effects as Embodiment 1.

[0039] Example 3

[0040] Please see Figure 3-5 This embodiment introduces a lightweight cable tray with a clamping mechanism 2, which is basically the same as the lightweight cable tray with a clamping mechanism 2 introduced in Embodiment 1. The difference is that the top rod 212 in this embodiment has an elongated structure with a length much larger than the cross-sectional size of the partition 3, and a width that matches the cross-sectional size of the partition 3. The bottom end of the partition 3 extends along the length direction of the cable tray body 1, forming a T-shape. The bottom end of the partition 3 passes through the opening and contacts the inner bottom end of the cable tray body 1. A screw hole is provided at the bottom end of the partition 3 for screwing a locking bolt. The axial direction of the locking bolt is consistent with the height direction of the partition 3. The bottom end of the locking bolt extends to the bottom of the cable tray body 1 and cooperates with a nut to lock the partition 3 onto the cable tray body 1. To facilitate the sliding of the partition 3 in the opening, a sliding hole is provided at the bottom end of the cable tray body 1 near the locking bolt, allowing the locking bolt to pass through the cable tray body 1. The length of the sliding hole is the same as the length of the opening, and there are at least two sliding holes, located on the two sides below the opening, so that the locking bolts can pass through the cable tray body to fix the partition 3.

[0041] This embodiment has the same beneficial effects as Embodiment 1.

[0042] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
