Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically an assembled cable tray. Background Technology

[0002] Cable trays are divided into trough-type cable trays, tray-type cable trays, ladder-type cable trays, and mesh cable trays. They can be installed independently or laid on various buildings and pipe rack supports. For convenient cable maintenance, assembled cable trays are needed to route cables.

[0003] A Chinese patent with authorization announcement number CN 218275943 U discloses an assembled cable tray including a cable tray body. Several cover plates are provided on the top outer wall of the cable tray body, and two connecting grooves are opened on the top outer wall of the cable tray body. Two connecting blocks are welded to the bottom outer wall of the cover plates, and the connecting blocks are inserted into the connecting grooves. A cavity is inserted inside the connecting block, and a limit block is slidably connected inside the cavity. A pressing rod is inserted inside the cavity, and a slider is welded to the bottom end of the pressing rod. The pressing rod extends through to the top outer wall of the cover plate. This invention, through the design of the cover plates, sliders, and limit blocks, allows for convenient installation and removal of the cover plates by workers. Since there are multiple cover plates, when problems occur with the cables inside the cable tray, workers can lift part of the cover plates to repair the cables, thereby reducing the workload of workers repairing the cables inside the cable tray and improving the efficiency of cable tray repair.

[0004] Existing modular cable trays cannot connect the tray and cover plate during assembly. When cable maintenance is required, the tray and cover plate must be disassembled. However, the cover plate is inconvenient to place at high altitudes, resulting in poor convenience for cable maintenance. Therefore, a modular cable tray is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes an assembled cable tray.

[0006] The technical solution adopted by this utility model to solve its technical problem is an assembled cable tray, including a cable tray with multiple heat dissipation holes on its side wall. A first mounting base is fixedly installed on the side wall of the cable tray, and a connecting rod is fixedly installed on the first mounting base. The length of the connecting rod is twice the length of the first mounting base. A cover plate is placed on the cable tray, and a second mounting base is installed on the cover plate. A connecting sleeve is installed on the second mounting base and is sleeved around the connecting rod. Two sets of fixing components are installed on the side wall of the cable tray. The fixing components include fixing blocks, which are fixedly connected to the side wall of the cable tray. A sliding groove is formed on the fixing block, and the inner wall of the sliding groove... A lead screw is rotatably mounted on the top, and a damping wheel is installed at one end of the lead screw. The side wall of the damping wheel is in contact with the outer wall of the fixed block. A slider is assembled in the sliding groove, and a positioning block is installed on the slider. The connecting rod and the connecting sleeve are rotatably connected, and the cable tray and the cover plate are rotatably connected through the connecting rod and the connecting sleeve. When cable maintenance is required, the two damping wheels are rotated in the opposite direction, which drives the two positioning blocks to move horizontally in opposite directions. The two positioning blocks unlock the cover plate, and then the cover plate is flipped over. The connecting sleeve on the cover plate rotates on the connecting rod, realizing the opening of the cover plate. This avoids removing the entire cover plate from the cable tray, solves the problem of inconvenient placement of the cover plate, and helps to improve the convenience of cable maintenance.

[0007] Preferably, two grooves are symmetrically formed on the cable tray base plate. Multiple limiting components are installed on the cable tray base plate. Each limiting component includes a limiting seat, which is L-shaped and placed on the cable tray base plate. A clamping element, U-shaped and made of plastic, is installed on the limiting seat. A threaded hole is formed on the limiting seat, and a threaded rod is fitted into the threaded hole. The threaded rod is fitted into the groove, and a knob is installed on the threaded rod. By placing the limiting seat on the cable tray base plate and then rotating the knob, the threaded rod rotates and moves downwards, moving into the groove, thus positioning the limiting seat. The cable is then placed in the clamping element, which clamps and secures the cable, achieving efficient cable limiting. The clamping element can be installed and removed, and can be installed according to the number of cables, avoiding messy cable routing and improving cable neatness.

[0008] The advantages of this utility model are:

[0009] 1. This utility model allows for the opening of a cable repair system by rotating two damping wheels in the opposite direction, which in turn moves two positioning blocks horizontally in the opposite direction. The two positioning blocks unlock the cover plate, and then the cover plate is flipped over. The connecting sleeve on the cover plate rotates on the connecting rod, thus opening the cover plate. This avoids removing the entire cover plate from the cable tray, solves the problem of inconvenient placement of the cover plate, and improves the convenience of cable repair.

[0010] 2. This utility model places the limiting seat on the base plate of the cable tray, then rotates the knob, causing the threaded rod to rotate and move downwards. The threaded rod moves into the groove, thus positioning the limiting seat. Then, the cable is placed in the clamp, which clamps and fixes the cable, achieving efficient cable limiting. The clamp can be installed and removed, and can be installed according to the number of cables, avoiding messy cable wiring and improving cable neatness. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-4As shown, an assembled cable tray includes a cable tray 1. Multiple heat dissipation holes 2 are provided on the side wall of the cable tray 1. A first mounting base 3 is fixedly installed on the side wall of the cable tray 1. A connecting rod 4 is fixedly installed on the first mounting base 3, and the length of the connecting rod 4 is twice the length of the first mounting base 3. A cover plate 5 is placed on the cable tray 1, and a second mounting base 6 is installed on the cover plate 5. A connecting sleeve 7 is installed on the second mounting base 6, and the connecting sleeve 7 is fitted around the connecting rod 4. Two sets of fixing components are installed on the side wall of the cable tray 1. The fixing components include fixing blocks 8, which are fixedly connected to the side wall of the cable tray 1. A sliding groove 9 is provided on the fixing block 8. A lead screw 10 is rotatably installed on the inner wall of the sliding groove 9. A damping wheel 11 is installed at one end of the lead screw 10, and the side wall of the damping wheel 11 is in contact with the outer wall of the fixing block 8. The cable tray is equipped with a slider 12, on which a positioning block 13 is installed. The connecting rod 4 and the connecting sleeve 7 are rotatably connected, and the cable tray 1 and the cover plate 5 are rotatably connected through the connecting rod 4 and the connecting sleeve 7. During operation, the existing assembled cable tray 1 cannot be connected to the cover plate 5 during the assembly process. When the cable needs to be repaired, the cable tray 1 and the cover plate 5 need to be disassembled. However, the cover plate 5 is inconvenient to place at high altitudes, resulting in poor convenience for cable repair. By aligning the connecting sleeve 7 on the cover plate 5 with the connecting rod 4 on the cable tray 1 during the assembly of the cover plate 5 and the cable tray 1, and then pushing the cover plate 5 to move on the cable tray 1, the connecting sleeve 7 is fitted onto the connecting rod 4. At this time, the cover plate 5 is rotatably connected to the cable tray 1, and the cover plate 5 covers the cable tray 1.

[0020] Then, the two damping wheels 11 are rotated, which drives the lead screw 10 to rotate. The lead screw 10 drives the slider 12 on it to move horizontally. The slider 12 drives the positioning block 13 to move horizontally. The two positioning blocks 13 are snapped onto the cover plate 5, realizing the fixed connection between the cable tray 1 and the cover plate 5. This structure avoids the cover plate 5 being snapped onto the cable tray 1. If the cover plate 5 is snapped onto the cable tray 1, the cover plate 5 needs to be pried open when disassembling the cover plate 5, which will cause the cover plate 5 or the cable tray 1 to deform, affecting the reassembly of the cover plate 5 and the cable tray 1.

[0021] When cable maintenance is required, the two damping wheels 11 are rotated in the opposite direction, which drives the two positioning blocks 13 to move horizontally in the opposite direction. The two positioning blocks 13 unlock the cover plate 5, and then the cover plate 5 is flipped over. The connecting sleeve 7 on the cover plate 5 rotates on the connecting rod 4, which realizes the opening of the cover plate 5. This avoids removing the cover plate 5 from the cable tray 1 as a whole, solves the problem of inconvenient placement of the cover plate 5, and helps to improve the convenience of cable maintenance.

[0022] Please see Figure 5As shown, two grooves 14 are symmetrically formed on the base plate of the cable tray 1. Multiple limiting components are installed on the base plate of the cable tray 1. Each limiting component includes a limiting seat 15, which is L-shaped and placed on the base plate of the cable tray 1. A locking piece 16, U-shaped and made of plastic, is installed on the limiting seat 15. A threaded hole is formed on the limiting seat 15, and a threaded rod 17 is fitted into the threaded hole. The threaded rod 17 is fitted into the groove 14, and a knob 18 is installed on the threaded rod 17. During operation, the existing assembled cable tray 1 makes it difficult to limit the cable during assembly, resulting in messy cable routing. To address the issue of poor cable neatness, the limiting seat 15 is placed on the base plate of the cable tray 1, with the limiting seat 15 positioned at both the inlet and outlet ends. At this point, the threaded rod 17 on the limiting seat 15 is aligned with the groove 14. Then, by rotating the knob 18, the threaded rod 17 rotates and moves downwards, moving into the groove 14, thus positioning the limiting seat 15. Afterward, the cable is placed in the clamp 16, which clamps and fixes the cable, achieving efficient cable positioning. The clamp 16 can be installed and removed, and can be installed according to the number of cables, avoiding messy cable routing and improving cable neatness.

[0023] Working principle: Existing modular cable trays 1 cannot be connected to the cover plate 5 during assembly. When cable maintenance is needed, the cable tray 1 and cover plate 5 must be disassembled. However, at heights, the cover plate 5 is inconvenient to place, resulting in poor convenience for cable maintenance. By aligning the connecting sleeve 7 on the cover plate 5 with the connecting rod 4 on the cable tray 1 during assembly, and then pushing the cover plate 5 on the cable tray 1, the connecting sleeve 7 is fitted onto the connecting rod 4. At this point, the cover plate 5 and cable tray 1 are rotatably connected. The cover plate 5 is placed on the cable tray 1. Then, rotating the two damping wheels 11 rotates the lead screw 10, which in turn moves the slider 12 horizontally. The slider 12 then moves the positioning blocks 13 horizontally, and the two positioning blocks 13 snap onto the cover plate 5, thus achieving a fixed connection between the cable tray 1 and the cover plate 5. This structure avoids the cover plate 5 being interlocked with the cable tray 1. If the cover plate 5 were interlocked with the cable tray 1, it would require prying open the cover plate 5 during disassembly, which could cause deformation of either the cover plate 5 or the cable tray 1, affecting the reassembly of the cover plate 5 and the cable tray 1. This also prevents cable repairs from being performed. At this time, by rotating the two damping wheels 11 in the opposite direction, the two positioning blocks 13 are driven to move horizontally in the opposite direction. The two positioning blocks 13 unlock the cover plate 5, and then the cover plate 5 is flipped over. The connecting sleeve 7 on the cover plate 5 rotates on the connecting rod 4, realizing the opening of the cover plate 5. This avoids removing the cover plate 5 from the cable tray 1 as a whole, solving the problem of inconvenient placement of the cover plate 5, and improving the convenience of cable maintenance. In the existing assembled cable tray 1, it is difficult to limit the cable position during the assembly process, resulting in messy cable wiring and poor cable neatness. By placing the limiting seat 15 on the base plate of the cable tray 1, the threaded rod 17 on the limiting seat 15 is aligned with the groove 14. Then, by rotating the knob 18, the threaded rod 17 is rotated and moved downwards, moving into the groove 14, thus positioning the limiting seat 15. After that, the cable is placed in the clamp 16, which clamps and fixes the cable, achieving efficient cable limiting. The clamp 16 can be installed and removed, and can be installed according to the number of cables, avoiding messy cable wiring and improving cable neatness.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
