Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, and specifically relates to a cable tray for preventing cable pulling in control cabinets. Background Technology

[0002] A control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements.

[0003] When the control cabinet is in use, external wiring is required. The external wiring is introduced through the cable tray to the cable tray at the top of the control cabinet, and then enters the control cabinet through the cable tray. Currently, traditional cable trays still have some problems in use. For example, traditional cable trays have a simple structure and are usually just a channel to hold cables. In actual wiring, the cables come into direct contact with the corner edges of the cable tray and rub against each other, which can easily cause wear on the cable sheath. This not only affects the appearance of the cables, but more importantly, it reduces the insulation performance of the cables. In addition, when the cables need to bend or change direction, due to the lack of effective guiding devices, the cables will be subjected to greater stress, which may cause damage to the internal structure of the cables and affect the stability of signal transmission or power supply. Utility Model Content

[0004] The purpose of this utility model is to provide a cable management tray for control cabinets that prevents cable pulling. Its advantages are good protection and convenient adjustment of cable management position.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable management tray for control cabinets to prevent cable pulling, comprising a frame, with grooves at both ends and the center of the frame, a movable block inside the groove, a connecting rod fixedly connected to the top of the movable block, a guide roller rotatably connected to the surface of the connecting rod, a limit groove inside the movable block, an adjustment mechanism inside the limit groove, an adjustment bolt threaded to the top of the connecting rod, symmetrically arranged locking blocks inside the limit groove, and symmetrically arranged sliding grooves inside the limit groove, the sliding grooves slidingly connected to the locking blocks.

[0006] The above technical solution is as follows: This utility model designs guide rollers inside the frame. The guide rollers can reduce the friction between the cable and the cable tray, protect the cable sheath, and allow the cable to move and be arranged smoothly within the cable tray, improving wiring efficiency. While guiding the cable in an orderly manner, it can also disperse the stress when the cable turns, ensuring the stability of the cable performance. Through the design of the locking block and sliding groove, the moving block can move inside the groove, allowing the guide roller to move inside the frame, making it suitable for different cables in different positions within the cable tray. The adjusting bolt and adjusting mechanism can fix the position of the guide roller, facilitating subsequent cable management.

[0010] The above technical solution is adopted: when the adjusting bolt is turned and moved downward, it can drive the conical block to move downward. Under the action of the inclined groove, the locking block is pushed out from the inside of the groove, so that it is locked with the inner wall of the sliding groove, thereby achieving the purpose of fixing the moving block.

[0011] The present invention is further provided that the interior of the frame is provided with a storage groove for storing the guide roller.

[0012] The above technical solution allows the guide rollers to be easily stored in the edge of the frame, avoiding interference with the cable management process.

[0013] The present invention is further provided that the frame is symmetrically provided with pressure plates for fixing cables inside.

[0014] The above technical solution allows for easy clamping of cables when they need to be secured, preventing them from shifting when pulled.

[0015] The present invention is further configured such that both ends of the pressure plate are fitted with limit bolts that are fixedly connected to the frame, and the top of the pressure plate is provided with a limit nut that is threadedly connected to the limit bolts.

[0016] The above technical solution involves adjusting and fixing the height of the pressure plate.

[0017] The present invention is further provided that the frame is provided with an installation groove for installing the limit bolt.

[0018] The above technical solution facilitates the installation of the limit bolts on the frame.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model designs guide rollers inside the frame, which can reduce the friction between the cable and the cable tray, protect the cable sheath, allow the cable to move and be arranged smoothly in the cable tray, improve wiring efficiency, guide the cable in an orderly manner, and also disperse the stress when the cable turns, ensuring the stability of the cable performance.

[0021] 2. This utility model, through the design of the locking block and sliding groove, allows the moving block to move inside the groove, and the guide roller to move inside the frame, making it suitable for different cables in different positions within the cable tray. The adjusting bolt and adjusting mechanism can fix the position of the guide roller, facilitating subsequent cable management. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 , Figure 2 and Figure 3 The control cabinet cable anti-pull cable management tray includes a frame 1. The frame 1 has grooves 2 at both ends and the center of the frame 1. The grooves 2 have movable blocks 3 inside. The top of the movable blocks 3 is fixedly connected to a connecting rod 4. The surface of the connecting rod 4 is rotatably connected to a guide roller 5.

[0029] refer to Figure 1 The frame 1 is made of aluminum alloy, which improves its durability.

[0030] refer to Figure 1 The frame 1 has a storage groove 13 inside for storing the guide roller 5. By setting the storage groove 13, the guide roller 5 can be easily stored in the edge of the frame 1, so as to avoid affecting the cable management work.

[0031] refer to Figure 1 The frame 1 has symmetrical pressure plates 14 for fixing cables inside. By setting the pressure plates 14, when it is necessary to fix the cable, it is convenient to press the cable tightly and prevent the cable from moving when it is pulled.

[0032] refer to Figure 1 Both ends of the pressure plate 14 are fitted with limit bolts 15 that are fixedly connected to the frame 1. The top of the pressure plate 14 is provided with a limit nut 11 that is threadedly connected to the limit bolts 15. By setting the limit bolts 15 and the limit nut 11, the height of the pressure plate 14 can be adjusted and fixed.

[0033] refer to Figure 1 The frame 1 has an installation slot 12 for installing the limit bolt 15. By setting the installation slot 12, it is convenient to install the limit bolt 15 on the frame 1.

[0034] Brief description of usage: When in use, after the installer places the cable inside the frame 1, the cable is positioned on the guide rollers 5 at both ends of the frame 1 and at the corners of the frame 1. When the cable is pulled, the cable contacts the guide rollers 5, which guide the cable to avoid direct contact between the cable sheath and the corners of the frame 1, thus ensuring that the cable sheath is not damaged. In addition, the guide rollers 5 can reduce the stress required when pulling the cable.

[0035] Example 2:

[0036] refer to Figure 1 , Figure 2 and Figure 3 The control cabinet cable management tray includes a frame 1. Grooves 2 are provided at both ends and the center of the frame 1. Movable blocks 3 are installed inside the grooves 2. A connecting rod 4 is fixedly connected to the top of the movable blocks 3. A guide roller 5 is rotatably connected to the surface of the connecting rod 4. A limiting groove 6 is provided inside the movable blocks 3. An adjusting mechanism 7 is provided inside the limiting groove 6. An adjusting bolt 8 is threadedly connected to the top of the connecting rod 4. Clamping blocks 9 are symmetrically arranged inside the limiting groove 6. Sliding grooves 10 are symmetrically arranged inside the limiting groove 6, and the sliding grooves 10 are slidably connected to the clamping blocks 9.

[0037] refer to Figure 3 The adjustment mechanism 7 includes an inclined groove 71 formed on the locking block 9. One end of the adjusting bolt 8 passes through the interior of the limiting groove 6 and is rotatably connected to a conical block 72 that is slidably connected to the inclined groove 71. By setting the inclined groove 71 and the conical block 72, when the adjusting bolt 8 is turned and moved downward, it can drive the conical block 72 to move downward. Under the action of the inclined groove 71, the locking block 9 is pushed out from the interior of the groove 2, so that it is locked with the inner wall of the sliding groove 10, thereby achieving the purpose of fixing the moving block 3.

[0038] Brief description of the usage process: When it is necessary to adjust the position of the guide roller 5 inside the frame 1, simply rotate the adjusting bolt 8 so that the adjusting bolt 8 drives the conical block 72 to move inside the limiting groove 6, so that the conical block 72 no longer applies pressure to the locking block 9. After the locking block 9 loses pressure, it is no longer locked to the inner wall of the sliding groove 10. At this time, the moving block 3 can move in the groove 2 inside the frame 1 to achieve the purpose of adjustment. The directional operation can limit the moving block 3.

[0039] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
