Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a wall-mounted cable tray. Background Technology

[0002] Cable trays are the main equipment used in infrastructure projects to protect cables and transmission lines. They are widely used in industries such as petroleum, chemical, and power. Generally, the base plate of the cable tray is enclosed. The heat generated by the cables in the enclosed tray accelerates the aging of the cable surface. Moreover, the enclosed design wastes materials and energy. Therefore, wall-mounted cables are often used in some indoor areas.

[0003] In patent document CN214958494U, a wall-mounted high-capacity cable tray is described, which includes a cable cover and a cable tray. A connecting plate is fixedly connected to one side of the cable tray, and a spiral connecting rod is rotatably connected to the inner side of the connecting plate. A rotating shaft is rotatably connected to one side of the connecting plate, and a snap-fit ​​plate is fixedly connected to one side of the rotating shaft. A lifting slide plate is slidably connected to the inner side of the rotating shaft and the outer side of the cable tray. The inner side of the lifting slide plate is rotatably connected to the outer side of the spiral connecting rod. This device, through the cooperation of the spiral connecting rod, snap-fit ​​plate, and lifting slide plate, allows the lifting slide plate to move up and down on the outside of the cable tray during installation. This, in turn, controls the distance between the snap-fit ​​plates by rotating the rotating shaft, enabling connection to existing wall panels without the need for secondary drilling with screws, thus preventing excessive damage to the wall. However, the above patent document still has the following drawbacks in practice:

[0004] In actual building facilities or industrial environments, with technological updates and business expansion, it is very likely that new cables will need to be laid. Since the cable tray area of ​​the device is fixed, when new cables are added, there may be insufficient space as there is no way to extend the space outward, leading to cable accumulation. Not only may workers need to spend a lot of time sorting through the cables to find the target cable during maintenance or repair, reducing work efficiency, but new cables laid in cable trays without enough space may not be placed according to the spacing required by safety regulations, increasing safety hazards. Therefore, we propose a wall-mounted cable tray to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a wall-mounted cable tray that can effectively solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A wall-mounted cable tray includes a mounting frame, a support plate fixedly connected to the front of the mounting frame, a plurality of arc-shaped grooves formed on the top of the support plate, an extension plate slidably connected to the inner wall of the support plate, a cable bundle assembly provided on the top of the support plate, and an extension assembly provided inside the support plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, such as Figure 1-5As shown, a wall-mounted cable tray includes a mounting frame 1, a support plate 11 fixedly connected to the front of the mounting frame 1, a plurality of arc-shaped grooves opened on the top of the support plate 11, an extension plate 12 slidably connected to the inner wall of the support plate 11, a cable bundle assembly 2 provided on the top of the support plate 11, and an extension assembly 3 provided inside the support plate 11.

[0026] Specifically, in order to ensure that new cables can be placed at the spacing required by safety regulations, refer to... Figure 4 and Figure 5 In this embodiment, the extension component 3 includes a worm gear 31, the top and bottom outer surfaces of the worm gear 31 are rotatably connected to the inner wall of the support plate 11, a motor 311 is fixedly connected to the bottom of the support plate 11, the output end of the motor 311 is fixedly connected to the bottom of the worm gear 31, and a worm wheel 312 is meshed with the back of the worm gear 31.

[0027] Further reading Figure 4 In this embodiment, two fixing blocks 32 are fixedly connected to the inner wall of the support plate 11, and the inner walls of the two fixing blocks 32 are rotatably connected to a rotating shaft 321. The outer surface of the rotating shaft 321 is fixedly connected to the inner wall of the worm gear 312.

[0028] During implementation, when new cables need to be laid due to technological updates and business expansion, the motor 311 is turned on to drive the worm gear 31 to rotate in the inner wall of the support plate 11. As the worm gear 31 rotates, it will drive the worm wheel 312 to rotate clockwise. As the worm wheel 312 rotates clockwise, it will drive the rotating shaft 321 to rotate in the inner wall of the two fixed blocks 32.

[0029] Further reading Figure 5 In this embodiment, bevel gear 322 is fixedly connected to both the left and right ends of the rotating shaft 321, and two threaded rods 33 are rotatably connected to the inner wall of the support plate 11. Bevel gear 331 is fixedly connected to the outer surface of the back of each of the two threaded rods 33.

[0030] Further reading Figure 5 In this embodiment, the back sides of the two bevel gears 331 are meshed with the front sides of the bevel gear 322 on the same side, and the outer surfaces of the two threaded rods 33 are threaded with moving blocks 332. The ends of the two moving blocks 332 that are close to each other are fixedly connected to the surface of the extension plate 12.

[0031] During implementation, when the rotating shaft 321 rotates clockwise, it drives two bevel gears 322 to rotate clockwise. During the clockwise rotation of bevel gears 322, two bevel gears 331 drive the threaded rod 33 on the left side to rotate clockwise within the inner wall of the support plate 11, and the threaded rod 33 on the right side to rotate counterclockwise within the inner wall of the support plate 11. Since the threads on the surfaces of the two threaded rods 33 are arranged in opposite directions, the two threaded rods 33 will simultaneously drive the moving blocks 332 on their surfaces to move forward. As the two moving blocks 332 move forward, they will also drive the extension plate 12 to move forward within the inner wall of the support plate 11, increasing the wiring area of ​​the device. This not only reduces the time required for workers to sort through cables when maintenance or repair is needed, improving work efficiency, but also provides sufficient space for the installation and laying of new cables, allowing them to be placed according to the spacing required by safety regulations, thus reducing safety hazards.

[0032] Example 2: This example is based on Example 1, with the addition of a wire harness assembly.

[0033] Specifically, to secure the cable within the arc-shaped groove at the top of the tray, refer to... Figure 3 In this embodiment, there are two wire harness assemblies 2, which are symmetrically arranged with the center of the tray 11. Each wire harness assembly 2 includes two fixing posts 21, and the bottom of each fixing post 21 is fixedly connected to the top of the tray 11.

[0034] Further reading Figure 3 In this embodiment, the inner walls of the two fixed columns 21 are slidably connected to a cable tray 22. A handle 23 is fixedly connected to the top center of the cable tray 22. The bottom of the cable tray 22 contacts the top of the support plate 11. Sliding rods 24 are fixedly connected to the top of both the front and back sides of the cable tray 22.

[0035] Further reading Figure 3 In this embodiment, the outer surfaces of the two slide rods 24 are slidably connected to the inner wall of the top wall of the fixed column 21 on the same side. The outer surfaces of the two slide rods 24 are fitted with springs 25. The tops of the two springs 25 are fixedly connected to the top of the inner wall of the fixed column 21 on the same side, and the bottoms of the two springs 25 are fixedly connected to the top of the cable tray 22.

[0036] During implementation, when cables need to be installed, the cable tray 22 is first pulled upward by the handle 23. As the cable tray 22 moves upward, it slides within the inner walls of the two fixed posts 21. Simultaneously, the upward movement of the cable tray 22 also causes the outer surfaces of the two sliding rods 24 to slide upward along the inner walls of the corresponding fixed posts 21. During the upward movement of the sliding rods 24, the springs 25 are compressed and deformed. After one end of the cable is passed through the bottom of the cable tray 22 and placed in the arc-shaped groove at the top of the support plate 11, releasing the handle 23 causes the deformed spring 25 to push the cable tray 22 downward due to its elasticity, thus fixing the cable in the arc-shaped groove. The two cable trays 22 can fix the two ends of the cable at the top of the support plate 11, allowing it to move easily. This not only ensures that the cables are neatly arranged, but also allows staff to quickly locate specific cables based on their arrangement and position, facilitating cable identification and maintenance. Furthermore, for cables with high signal transmission requirements, such as data cables and fiber optic cables, a stable position ensures that signal transmission is not interfered with.

[0037] The working principle of this utility model is as follows: When it is necessary to install cables, firstly, pull the cable tray 22 upward by the handle 23. When the cable tray 22 moves upward, it will slide in the inner wall of the two fixed posts 21. At the same time, when the cable tray 22 moves upward, it will also drive the outer surface of the two sliding rods 24 to slide upward on the inner wall of the top of the corresponding fixed posts 21. During the upward movement of the sliding rods 24, they will compress the springs 25 to deform them. After passing one end of the cable through the bottom of the cable tray 22 and placing it in the arc-shaped groove opened on the top of the support plate 11, release the handle 23. The deformed springs 25 will push the cable tray due to the elastic force. The cable tray 22 moves downwards to secure the cable within the arc-shaped groove. Two cable trays 22 secure the cable at both ends of the top of the support plate 11, allowing for easy movement. This not only ensures neat cable arrangement but also allows workers to quickly locate specific cables based on their arrangement and position, facilitating cable identification and maintenance. Furthermore, for cables with high signal transmission requirements, such as data cables and fiber optic cables, a stable position ensures interference-free signal transmission. When new cables need to be laid due to technological updates and business expansion, the motor can be turned on. 311 drives the worm gear 31 to rotate within the inner wall of the support plate 11. Simultaneously, the rotation of the worm gear 31 causes the worm wheel 312 to rotate clockwise. The clockwise rotation of the worm wheel 312, in turn, causes the rotating shaft 321 to rotate within the inner walls of the two fixed blocks 32. The clockwise rotation of the rotating shaft 321 causes the two bevel gears 322 to rotate clockwise. During this clockwise rotation, the two bevel gears 331 drive the threaded rod 33 on the left side to rotate clockwise within the inner wall of the support plate 11, and the threaded rod 33 on the right side to rotate counterclockwise within the inner wall of the support plate 11. The threads on the surfaces of the two threaded rods 33 are arranged in opposite directions, so the two threaded rods 33 will simultaneously drive the moving blocks 332 on their surfaces to move forward. As the two moving blocks 332 move forward, they will also drive the extension plate 12 to move forward in the inner wall of the support plate 11, increasing the wiring area of ​​the device. This not only reduces the time required for workers to sort out cables when they need to maintain or repair them, thus improving their work efficiency, but also provides sufficient space for the installation and laying of new cables, allowing them to be placed according to the spacing required by safety regulations, thereby reducing safety hazards.
