Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and more specifically, to a fiberglass cable tray with positioning function. Background Technology

[0002] Cable trays are rigid structural systems composed of straight sections, bends, components, brackets, and hangers of trays or ladders, providing dense support for cables. They are important products for power transmission in the low-voltage power transmission and distribution field and are widely used in buildings, industrial and mining sites. Fiberglass cable trays are composed of glass fiber reinforced plastic, flame retardants, and other materials. Due to the low thermal conductivity of the selected materials and the addition of flame retardants, the products not only have fire resistance, heat insulation, and self-extinguishing properties, but also high corrosion resistance. They also have advantages such as lightweight structure, aging resistance, and safety and reliability. Therefore, they are widely used in chemical, metallurgical, and petrochemical enterprises in chemically corrosive environments such as acids and alkalis.

[0003] Existing fiberglass cable trays consist of a tray and a cover plate. Both the cover plate and the tray have threaded holes. During use, multiple sets of bolts are required to fix the cover plate to the tray, which is time-consuming and laborious. It is also inconvenient to quickly disassemble and assemble the cover plate, resulting in poor ease of use of the device.

[0004] A search revealed that Chinese patent CN218275920U discloses a fiberglass cable tray. The cover plate contacts the top of the main body of the cable tray and seals the top of the main body of the cable tray. At this time, the cover plate is fixed by limiting and fixing the limiting and fixing block through the fixing component, avoiding the need to fix the cover plate by tightening multiple sets of bolts. This saves time and effort, and makes it easy for workers to quickly disassemble and assemble the cover plate, thus improving the ease of use of the device.

[0005] In actual use, the aforementioned fiberglass cable trays are connected by welding or a large number of bolts during installation, which is a rather cumbersome process. It is also inconvenient to align and position two trays during installation. When it is necessary to disassemble and replace some trays, the complicated operation process will affect the construction progress and reduce construction efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fiberglass cable tray with positioning function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fiberglass cable tray with positioning function includes two tray bodies, a cover plate is installed on the top of the tray body, a connecting component and a plurality of positioning mechanisms are installed inside the tray body, and the connecting component is installed on one side of the positioning mechanism;

[0009] The connecting assembly includes a first fixed plate, which is fixedly connected to the inside of the cable tray body. Two support plates are fixedly connected to one side of the first fixed plate. A bidirectional screw is rotatably connected inside the support plate. A hexagonal nut is fixedly connected to the outside of the bidirectional screw. Two movable plates are threadedly connected to the outside of the bidirectional screw. The movable plates are slidably connected to the inside of the first fixed plate. A connecting rod and a limiting block are fixedly connected to one side of the movable plate. The limiting block is installed on one side of the connecting rod. A second fixed plate is fixedly connected inside the cable tray body. Both limiting blocks are inserted into the inside of the second fixed plate. The movable plates are slidably connected to the inside of the second fixed plate. Two fixed plates are fixedly connected to one side of the second fixed plate. A threaded rod is rotatably connected inside the fixed plate. A knob is fixedly connected to the top of the threaded rod. A movable plate is fixedly connected to the outside of the threaded rod. Two insert rods are fixedly connected to the bottom of the movable plate. The insert rods are inserted into the top of the limiting blocks.

[0010] By adopting the above technical solution, the two cable tray bodies can be quickly and stably connected, which simplifies the construction operation.

[0011] As a further description of the above technical solution: the positioning mechanism includes a positioning plate, which is fixedly connected to the inside of the cable tray body. Three limiting rings are provided on the inner side of the positioning plate, two of which are slidably connected to the inner side of the positioning plate. A slider is fixedly connected to one side of the limiting ring, and a groove is opened on the other side of the limiting ring. Multiple telescopic springs are fixedly connected inside the limiting ring, and a fitting ring is fixedly connected to one end of each telescopic spring.

[0012] By adopting the above technical solution, the components can be arranged side by side during installation, which facilitates later identification and management.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a connecting component, compared with the existing technology, the two cable tray bodies can be connected by inserting two plug rods into the second fixing plate, and the two moving plates can be limited by inserting two plug rods into the limiting block. This double fixation can ensure that the two cable tray bodies can be stably connected, reducing loosening caused by vibration or external force. Installation and disassembly can be completed quickly by rotating the hexagonal nut and knob, which simplifies the construction operation and helps to improve construction efficiency.

[0015] 2. By setting up a positioning mechanism, compared with existing technologies, the limiting ring can adapt to cables of different sizes and can be arranged side by side during installation. This can reduce cable cross-entanglement, reduce the risk of insulation layer damage caused by mutual compression of cables, and facilitate later identification and management.

The two movable plates 6 are inserted into the second fixed plate 9, and the bidirectional screw 4 is rotated. The bidirectional screw 4 can drive the two movable plates 6 to move relative to each other through the thread, so that the two connecting rods 7 can be inserted into the second fixed plate 9 to connect the two cable tray bodies 1.

[0027] Working principle of this utility model: This utility model designs a fiberglass cable tray with positioning function, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation between various structures, when it is necessary to assemble two cable tray bodies 1, firstly, the two movable plates 6 inside one cable tray body 1 are inserted into the second fixed plate 9 inside the other cable tray body 1. Then, the hexagonal nut 5 is rotated using a tool, so that the hexagonal nut 5 can drive the double-ended screw 4 to rotate. Using the opposite thread direction on the outer side of the double-ended screw 4, the double-ended screw 4 can drive the movable plate 6 to move through the thread. The relative movement of the two movable plates 6 can drive the connecting rod 7 to be inserted into the second fixed plate 9, so that the two cable tray bodies 1 can be connected. Then, the knob 12 is rotated, which can drive the threaded rod 11 to rotate, so that the threaded rod 11 can drive the movable plate 13 downward through the thread. The movable plate 13 can drive the insertion rod 14 to insert into the limiting block 8, so as to limit the two limiting blocks 8, thereby allowing the two connecting rods 7 to be tightly connected to the second fixed plate 9, and the two cable tray bodies 1 to be stably connected. Then, the cable is inserted into the inside of the limiting ring 16. The multiple telescopic springs 19 extend and retract, allowing the multiple fitting rings 20 to adapt to cables of different sizes, so that the limiting ring 16 can fix the cable. Through the sliders 17 and the grooves 18 on both sides of the limiting ring 16, the three limiting rings 16 can be spliced ​​together. Then, the three parallel limiting rings 16 are inserted into the positioning plate 15. The positioning plate 15 can position the parallel limiting rings 16, so that the three cables can be neatly arranged inside the cable tray body 1.
