Description

Technical Field

[0001] This utility model relates to a ladder-type cable tray, belonging to the technical field of cable tray equipment. Background Technology

[0002] Ladder-type cable trays are widely used cable management devices in industrial, commercial, and public facilities. Their design is based on a trapezoidal structure and has advantages such as efficient heat dissipation, convenient maintenance, high load-bearing capacity, and flexible adaptability. They have become an important part of modern cable laying systems. For example, a ladder-type cable tray mentioned in authorization announcement number CN214850221U includes two side rods and several ladder sections fixed at intervals between the two side rods. The side rods include several telescopic rods that are linearly connected. The telescopic rods include a first sleeve and a second sleeve that is sleeved on the inner wall of the first sleeve and slidably connected to it.

[0003] In this device, the telescopic adjustment facilitates the installation of the cable tray. However, in actual application, the position needs to be limited by bolts when making telescopic adjustments. If multiple adjustments are required, the bolts need to be turned repeatedly, which is very inconvenient to use. Furthermore, when the bolts are loose, the cable tray is not stable enough. Also, when there are too many cables, it is difficult to easily layer the cables, which is not conducive to the heat dissipation of the cables. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a ladder-type cable tray.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ladder-type cable tray, including a sleeve tube, a limit box fixedly connected to the outer surface of the sleeve tube, a movable plate slidably connected to the inner cavity of the limit box, a limit post fixedly connected to one side surface of the movable plate, a limit spring provided in the inner cavity of the limit box, a bonding plate fixedly connected to the outer surface of one end of the limit post, a bonding bolt threadedly connected to the outer surface of the bonding plate, a telescopic rod slidably connected to the inner cavity of the sleeve tube, a first ladder baffle fixedly connected to both the outer surface of the telescopic rod and the outer surface of the sleeve tube, a first connecting post fixedly connected to the top surface of the first ladder baffle, a second connecting post above the first connecting post, a connecting ring threadedly connected to the outer surface of the second connecting post, and a second ladder baffle fixedly connected to the top of the second connecting post.

[0006] Preferably, one end of the limiting spring is fixedly connected to the moving plate, and the other end of the limiting spring away from the moving plate is fixedly connected to the limiting box.

[0007] Preferably, the end of the limiting post away from the bonding plate is movably connected to the limiting box, and the outer surface of the telescopic rod is provided with a limiting hole that matches the structural size of the limiting post.

[0008] Preferably, a protruding rod is fixedly connected to the outer surface of one end of the fitting bolt, and a threaded hole matching the structural size of the fitting bolt is opened on the side surface of the limiting box near the fitting plate.

[0009] Preferably, a plug rod is fixedly connected to the top of the first connecting post, and a slot matching the structural dimensions of the plug rod is opened on the surface of the second connecting post near the first connecting post.

[0010] Preferably, the outer surfaces of the first connecting post and the second connecting post are both provided with threaded layers that match the structural dimensions of the inner surface of the connecting ring, and the outer surface of the connecting ring is provided with an anti-slip textured layer.

[0011] Preferably, a side plate is fixedly connected to the top surface of the second ladder baffle, and both the top surface of the second ladder baffle and the top surface of the first ladder baffle are smooth surfaces.

[0012] The beneficial effects of this utility model are:

[0013] This utility model, by setting up a limiting box, a movable plate, a limiting post, a limiting spring, a fitting plate, and a fitting bolt, allows for convenient limiting operations when adjusting the length of the sleeve tube and the telescopic rod. This avoids repeatedly tightening the bolts to adjust the limit, reducing the workload of operators and making it more user-friendly. Even if the bolts are loose, the overall connection between the sleeve tube and the telescopic rod remains relatively stable. The limiting post is inserted into the limiting hole to initially limit the overall connection between the sleeve tube and the telescopic rod. By setting up a second ladder baffle, a first connecting post, a second connecting post, and a connecting ring, the cable can be laid in layers when the amount of cable laid is too large, which is beneficial for the heat dissipation of the cable.

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.

[0021] Example 1

[0022] Please see Figure 1-4 This utility model provides the following technical solution: a ladder-type cable tray, including a sleeve tube 1, a limit box 2 fixedly connected to the outer surface of the sleeve tube 1, a movable plate 3 slidably connected to the inner cavity of the limit box 2, a limit post 4 fixedly connected through one side surface of the movable plate 3, a limit spring 5 provided in the inner cavity of the limit box 2, a bonding plate 6 fixedly connected to one end of the outer surface of the limit post 4, a bonding bolt 7 threadedly connected through the outer surface of the bonding plate 6, a telescopic rod 8 slidably connected to the inner cavity of the sleeve tube 1, one sleeve tube 1 and the telescopic rod 8 forming a combination, multiple sleeve tube 1 and telescopic rod 8 combinations being welded and fixedly connected to each other to form the side of the cable tray, a first ladder baffle 9 fixedly connected to the outer surface of the telescopic rod 8 and the outer surface of the sleeve tube 1, a first connecting post 10 fixedly connected to the top surface of the first ladder baffle 9, a second connecting post 11 provided above the first connecting post 10, a connecting ring 12 threadedly connected to the outer surface of the second connecting post 11, and a second ladder baffle 13 fixedly connected to the top of the second connecting post 11.

[0023] In use, after fixing and connecting the multiple sleeves 1 and the telescopic rod 8 together, install them in the required position, lay the cable above the first ladder baffle 9 to support the cable and avoid cable mess.

[0024] As a preferred technical solution of the ladder-type cable tray of this utility model, a protruding rod 15 is fixedly connected to the outer surface of one end of the fitting bolt 7, and a threaded hole matching the structural size of the fitting bolt 7 is opened on the side surface of the limiting box 2 near the fitting plate 6; the fitting bolt 7 can be rotated more conveniently through the protruding rod 15, and the fitting bolt 7 is inserted through the fitting plate 6 into the threaded hole on the surface of the limiting box 2, so as to fix the fitting plate 6 and the limiting box 2 together.

[0025] As a preferred technical solution of the ladder-type cable tray of this utility model, a plug rod 16 is fixedly connected to the top of the first connecting post 10, and a slot matching the structural size of the plug rod 16 is opened on the surface of the second connecting post 11 near the first connecting post 10; both the outer surface of the first connecting post 10 and the outer surface of the second connecting post 11 are provided with a threaded layer matching the structural size of the inner surface of the connecting ring 12, and an anti-slip textured layer is opened on the outer surface of the connecting ring 12; the plug rod 16 at the top of the first connecting post 10 is inserted into the slot below the second connecting post 11, and then the connecting ring 12 is rotated to the position of the outer surface of the first connecting post 10 and the second connecting post 11, connecting the first connecting post 10 and the second connecting post 11.

[0026] As a preferred technical solution of the ladder-type cable tray of this utility model, a side plate 17 is fixedly connected to the top surface of the second ladder baffle 13. The top surface of the second ladder baffle 13 and the top surface of the first ladder baffle 9 are both smooth surfaces. The length of the second ladder baffle 13 is smaller than that of the first ladder baffle 9. The side plate 17 prevents the cable from falling through the gap between the second ladder baffle 13, the sleeve tube 1, and the telescopic rod 8.

[0027] Example 2

[0028] Please see Figure 2 and Figure 3 The difference between this embodiment and Embodiment 1 is that:

[0029] One end of the limiting spring 5 is fixedly connected to the moving plate 3, and the other end of the limiting spring 5 away from the moving plate 3 is fixedly connected to the limiting box 2; the end of the limiting post 4 away from the bonding plate 6 is movably connected through the limiting box 2, and the outer surface of the telescopic rod 8 is provided with a limiting hole 14 that matches the structural dimensions of the limiting post 4; when the limiting post 4 protrudes from the limiting box 2, the moving plate 3 and the limiting post 4 assembly are moved, the limiting spring 5 is compressed and deformed, and when the limiting post 4 is inserted into the limiting hole 14, the telescopic rod 8 is stably connected to the sleeve tube 1, and the overall length of the sleeve tube 1 and the telescopic rod 8 is fixed and will not change easily.

[0030] The working principle and usage process of this utility model are as follows: When installing the cable tray, if it is necessary to change the overall length of the cable tray, loosen the fitting bolt 7, and then pull the limiting post 4 at one end of the limiting box 2. The limiting post 4 drives the moving plate 3 to slide and engage within the cavity of the limiting box 2. As the limiting post 4 moves, the end of the limiting post 4 away from the fitting plate 6 disengages from the limiting hole 14 on the outer surface of the telescopic rod 8, releasing the limitation on the telescopic rod 8. At this time, the telescopic rod 8 can be easily adjusted in the sleeve tube 1. Then, loosen the limiting post 4, and under the action of the limiting spring 5, insert the limiting post 4 into the corresponding limiting hole 14 to adjust the overall length of the sleeve tube 1 and the telescopic rod 8. This process is repeated in sequence. The multiple sleeve tubes 1 and telescopic rods 8 assemblies are adjusted. Further, by rotating the mounting bolts 7 through the protruding rods 15, the mounting bolts 7 are threaded and connected to the mounting plate 6, and the mounting plate 6 is fixedly connected to the limiting box 2. At this time, the stability of the sleeve tubes 1 and telescopic rods 8 assemblies is ensured. Furthermore, if too many cables are laid, the insertion rod 16 at the top of the first connecting post 10 is inserted into the slot below the second connecting post 11, and then the connecting ring 12 is rotated to the outer surface position of the first connecting post 10 and the second connecting post 11 to connect the first connecting post 10 and the second connecting post 11. The first ladder baffle 9 and the second ladder baffle 13 are connected to lay the cables in layers, which is conducive to the heat dissipation of the cables.
