Description

Technical Field

[0001] This utility model relates to the field of fiberglass cable trays, and in particular to a high-strength fiberglass cable tray. Background Technology

[0002] Fiberglass cable trays are cable support devices made of glass fiber reinforced plastic (FRP). They are lightweight, high-strength, corrosion-resistant, and have good insulation properties, making them widely used in power, chemical, construction, and marine engineering industries. High-strength fiberglass cable trays, based on traditional fiberglass, utilize optimized material ratios and process design to achieve higher mechanical strength and load-bearing capacity. They maintain stability and durability under heavy loads and harsh environments (such as humid and highly corrosive locations). They are widely used in power transmission and distribution, rail transportation, sewage treatment, offshore oil platforms, and other applications requiring high strength and long service life, meeting the demands of modern engineering for high-performance cable trays.

[0003] However, existing FRP (fiberglass reinforced plastic) cable trays still have some shortcomings in terms of connection, fixation, and maintenance. First, the connection of two U-shaped plates typically relies on traditional fixing methods such as bolts, which is not only cumbersome and time-consuming to install, but also prone to connection instability in vibrating environments. Second, the fixing structure is relatively simple, lacking a mechanism for rapid installation and disassembly, resulting in low construction efficiency, especially in large-scale cabling projects where labor costs are high. Finally, in terms of cable inspection and maintenance, traditional designs usually require disassembling the top or side panels, a complex and time-consuming operation that prevents quick observation of the cable's operating status, affecting the efficiency and convenience of maintenance work.

[0004] To address the above problems, a high-strength fiberglass cable tray is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-strength fiberglass cable tray, which aims to address the problems of unstable connections, cumbersome installation, and inconvenient maintenance of existing fiberglass cable trays.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength fiberglass cable tray, comprising a U-shaped plate and a straight plate, wherein sliders are fixedly connected to both sides of the top of the U-shaped plate, and fixing grooves are provided on both sides of the bottom of the straight plate. The sliders slide on the bottom of the straight plate until they slide into the interior of the fixing grooves. Fixing recesses are provided on both sides of one end of the U-shaped plate, and fixing components are provided inside the fixing recesses. Fixing protrusions are provided at the other end of the U-shaped plate, and two fixing holes are provided inside the fixing protrusions. A quick observation component for quickly observing the cable condition is provided in the side wall of the U-shaped plate. An auxiliary connection component for assisting in the installation of the fiberglass cable tray is provided at the end of the U-shaped plate.

[0007] The fixing component includes two pins, a base is installed between the bottoms of the two pins, the base slides inside the inner groove, springs are fixedly connected to both sides of the bottom of the base, and a lever is fixedly connected to the side of the base away from the inside of the U-shaped plate, and the lever slides in the side wall of the U-shaped plate.

[0008] As a further description of the above technical solution:

[0009] The bottom of the fixing concave block has an inner groove and two circular grooves, and the two pins are inserted into the inner fixing holes of the fixing protrusion under the action of the spring.

[0010] As a further description of the above technical solution:

[0011] The bottoms of the two springs are fixedly connected to the bottom wall of the circular groove, and the tops of the two springs are fixedly connected to the bottom of the base.

[0012] As a further description of the above technical solution:

[0013] Limiting grooves are provided on both sides of the inner groove, and limiting blocks are fixedly connected to both sides of the base. The limiting blocks are slidably connected inside the limiting grooves.

[0014] As a further description of the above technical solution:

[0015] The auxiliary connection assembly includes an irregular plate and several connecting rods. The irregular plate and connecting rods are located on one side of the U-shaped plate, while the other side of the U-shaped plate has connecting holes and irregular inner grooves corresponding to the number and size of the connecting rods and the irregular plate.

[0016] As a further description of the above technical solution:

[0017] The connecting rod is inserted into the interior of the connecting hole, and the irregular plate is inserted into the interior of the irregular inner groove.

[0018] As a further description of the above technical solution:

[0019] The outer side of the connecting rod is fitted with an elastic material that deforms under compressive force.

[0020] As a further description of the above technical solution:

[0021] The rapid observation component includes an observation window located on one side wall of the U-shaped plate. The side wall of the U-shaped plate has a sliding groove for the observation window to slide. A toggle block is fixed to the front end of the observation window, and two dampers are also provided inside the sliding groove.

[0022] As a further description of the above technical solution:

[0023] One end of the damper is fixed inside the U-shaped plate, while the other end of the damper is fixedly connected to the observation window.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, an efficient and stable splicing connection is achieved by setting an auxiliary connecting component between two U-shaped plates. Specifically, multiple connecting rods on one U-shaped plate are inserted into pre-set connecting holes on the other U-shaped plate, while an elastic material is sleeved on the outside of the connecting rods. Irregular plates can also be inserted into irregular inner grooves simultaneously. This design not only ensures a fast and smooth connection process but also effectively prevents connection instability. Furthermore, the elastic material has excellent cushioning properties, absorbing external vibrations and providing shock absorption and stability, making it particularly suitable for applications with high vibration environments.

[0026] 2. In this utility model, a snap-fit ​​fixing component allows two U-shaped plates to be quickly connected together, replacing the traditional bolt connection method. Specifically, a fixing protrusion on one U-shaped plate snaps into a fixing recess on the other U-shaped plate. A spring-loaded fixing component is also provided at the fixing recess. When the fixing protrusion is inserted into the recess, two pins on the base are pushed upwards out of the inner groove under the spring force and inserted into the pre-set insertion holes inside the fixing protrusion. The user only needs to slide a lever to control the base and pins, achieving a quick and stable connection, greatly saving installation time and labor costs.

[0027] 3. In this invention, a groove is formed on one side wall of the U-shaped plate, and a sliding observation window is installed within the groove. The opening and closing of the observation window can be controlled by moving a lever. This design allows users to easily observe and inspect the cables inside the fiberglass trough-type cable tray without disassembling the top plate or U-shaped plate, greatly improving the convenience of maintenance and repair and reducing operation time. Furthermore, the observation window design also allows for real-time monitoring of the cable operating status during daily use, facilitating timely detection and resolution of faults.

[0036] 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 protection scope of the present utility model.

[0037] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a high-strength fiberglass cable tray, comprising a U-shaped plate 1 and a straight plate 2. Slider blocks 8 are fixedly connected to both sides of the top of the U-shaped plate 1, and fixing grooves 9 are formed on both sides of the bottom of the straight plate 2. The sliders 8 slide on the bottom of the straight plate 2 until they slide into the fixing grooves 9, achieving quick connection and positioning between the U-shaped plate 1 and the straight plate 2. Fixing recesses 3 are provided on both sides of one end of the U-shaped plate 1. Fixing components 5 are provided inside the fixing recesses 3. An inner groove 502 and two circular grooves 506 are formed at the bottom of the fixing recesses 3. The fixing components 5 include two pins 501, and a base 503 is installed between the bottoms of the two pins 501. The base 503 slides inside the inner groove 502 and achieves stable sliding through a limiting structure. Specifically, limiting grooves 508 are formed on both sides of the inner groove 502, and limiting blocks 507 are fixedly connected to both sides of the base 503. The limiting blocks 507 are slidably connected inside the limiting grooves 508 to ensure that the base 503 does not shift during sliding. The bottoms of two pins 501 are fixed to the base 503, and springs 504 are fixedly connected to both sides of the bottom of the base 503. The bottoms of the two springs 504 are fixedly connected to the bottom wall of the circular groove 506, and the tops are fixedly connected to the bottom of the base 503. Under the action of the springs 504, the pins 501 can be pushed upward and inserted into the internal fixing holes of the fixing protrusion 4 at the other end of the U-shaped plate 1, thereby realizing the quick fixed connection of the two U-shaped plates 1. A lever 505 is fixedly connected to the side of the base 503 away from the inside of the U-shaped plate 1. The lever 505 slides in the side wall of the U-shaped plate 1. By sliding the lever 505, the insertion and removal of the pins 501 can be easily controlled, simplifying the installation and disassembly process.

[0038] Reference Figure 1 - Figure 2An auxiliary connecting component 6 is also provided at the end of the U-shaped plate 1. The auxiliary connecting component 6 includes an irregular plate 601 and several connecting rods 602. The irregular plate 601 and the connecting rods 602 are located on one side of the U-shaped plate 1, while the other side of the U-shaped plate 1 has connecting holes 603 and irregular inner grooves 604 corresponding to the number and size of the connecting rods 602 and the irregular plate 601. An elastic material is sleeved on the outside of the connecting rods 602. When the connecting rod 602 is inserted into the connecting hole 603 inside another U-shaped plate 1, the elastic material deforms under the action of extrusion force, thereby providing a more stable connection effect. At the same time, the irregular plate 601 is inserted into the irregular inner groove 604 to assist in the quick installation and stable connection of the U-shaped plate 1.

[0039] Reference Figure 2 , Figure 5 and Figure 6 A quick observation assembly 7 is provided on the side wall of the U-shaped plate 1. The quick observation assembly 7 includes an observation window 701, which is slidably connected to the side wall of the U-shaped plate 1. Specifically, a slide groove 703 is formed in the side wall of the U-shaped plate 1, and a lever 702 is fixed to the front end of the observation window 701. The user can control the observation window 701 to slide within the slide groove 703 by moving the lever 702, thereby realizing quick observation and inspection of the cable condition within the cable tray. To improve the smoothness and safety of sliding, two dampers 704 are also provided inside the slide groove 703. One end of the damper 704 is fixed inside the U-shaped plate 1, and the other end is fixedly connected to the observation window 701, effectively buffering the impact force during sliding and ensuring that the observation window 701 opens and closes smoothly and stably.

[0040] Working principle: First, the U-shaped plate 1 and the straight plate 2 are quickly slidably connected and positioned by the cooperation of the slider 8 and the fixing groove 9. Then, the fixing protrusion 4 at one end of the U-shaped plate 1 is inserted into the fixing recess 3 at the other end. With the help of the pin 501 and spring 504 in the fixing component 5, automatic locking is achieved. The pin 501 is inserted into the fixing hole, and the insertion and withdrawal of the pin 501 is controlled by the lever 505 to ensure a stable connection. Second, the auxiliary connecting component 6, namely the irregular plate 601 and the connecting rod 602, is inserted into the corresponding connecting hole 603 and irregular inner groove 604 to further improve the connection strength. The elastic material provides shock absorption. Finally, a quick observation component 7 is set on the side wall of the U-shaped plate 1, including an observation window 701 and a sliding groove 703. The sliding of the observation window is controlled by the lever 702, and the damper 704 achieves smooth opening and closing, which facilitates quick observation and maintenance of the internal cable status.
