Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a modular combined cable tray. Background Technology

[0002] Cable trays are classified into trough type, tray type, and ladder type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building structures and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are widely used in the cable tray industry. Tray-type cable trays are the most widely used and ideal laying device in petroleum, chemical, power, television, and telecommunications industries. They have advantages such as light weight, high load capacity, beautiful appearance, simple structure, convenient installation, and good heat dissipation and ventilation. They are suitable for both power cable installation and control cable laying.

[0003] For example, utility model patent CN218415643U discloses a combined cable tray, including a tray, a base plate, and a top plate. The base plate is mounted inside the tray via a bracket. Sliding grooves are provided on both sides of the tray, and sliders are slidably connected within these grooves. A top plate for organizing and limiting cables is located between the sliders. An insertion block is provided on one side of each slider. Slots corresponding to the insertion blocks are provided on both sides of the top plate, and these slots are slidably connected to the insertion blocks. This utility model of a combined cable tray is simple in structure, easy to operate, flexible and stable in use, and has high practical value, making it suitable for widespread promotion and use. However, it has the problem of not being able to effectively limit cables of different outer diameters. This can lead to situations where cables of the same size are adequately limited during installation, but cables of different sizes are not fully limited. Ultimately, this results in loose cable installation and poor applicability of the device during use. Therefore, we propose a modular combined cable tray. Utility Model Content

[0004] The purpose of this invention is to provide a modular and combined cable tray to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular combined cable tray, including a cable tray body, with sliding grooves on both sides inside the cable tray body. A cable limiting assembly is provided within the cable tray body, comprising multiple inner cable limiting plates. Each inner cable limiting plate has multiple linearly distributed springs connected to its upper end. The springs are connected to cable limiting grooves opened at the inner ends of outer cable limiting plates. Threaded moving plates are connected to both sides of the outer cable limiting plates, and the threaded moving plates are slidably connected to the sliding grooves. Each threaded moving plate on the same side is threadedly connected to a rotating rod. Two symmetrical threaded grooves are opened on the outer periphery of each rotating rod. Each threaded moving plate is slidably connected to the sliding groove. A contact plate is rotatably connected to the upper end of each rotating rod, and the contact plate is connected to the cable tray body.

[0006] Preferably, the end of the rotating rod away from the contact plate is connected to a rotating shaft, the rotating shaft is connected to a rotating handle, the upper end of the rotating handle abuts against the cable tray body, and the rotating handle is located on the outside of the cable tray body. The rotating handle is used to rotate the rotating rod, thereby displacing the threaded moving plate.

[0007] Preferably, the front end of the cable tray body has a slot, and two symmetrically arranged arc-shaped opening slots are opened on both sides of the cable tray body. Each arc-shaped opening slot is connected to the slot. An insert plate is connected to the end of the cable tray body away from the slot. Locking screw holes are opened on both front ends of the insert plate. Locking bolts are installed in the arc-shaped opening slots. The locking bolts are matched with the locking screw holes. When the insert plate of one cable tray body is inserted into the slot of another cable tray body, and the locking screw holes on both sides of the insert plate are aligned with the arc-shaped opening slots on both sides of the cable tray body, the locking bolts are screwed into the locking screw holes to achieve a firm connection between the cable trays.

[0008] Preferably, each of the inner cable limiting plates has a guide post connected to the middle of its upper end. The guide post is slidably connected to the outer cable limiting plate, and the guide post ensures the stability of the movement of the outer cable limiting plate.

[0009] Preferably, the lower end of the cable outer limiting plate is connected to a plurality of evenly distributed blocking plates. The length of the blocking plates is equal to the length of the cable tray body. The blocking plates can block the cables on both sides to prevent mutual interference between the cables.

[0010] Preferably, the lengths of the outer cable limiting plate and the inner cable limiting plate are matched with the dimensions of the cable tray body, and the width of the outer cable limiting plate is smaller than the width of the cable tray body, so as to ensure that when the two cable tray bodies are closed, the outer cable limiting plate can also be closed, and the cable will not become loose.

[0011] Preferably, the inner cable limiting plate is semi-circular in shape, and the inner diameter of the cable limiting groove is larger than the outer diameter of the inner cable limiting plate, so that the inner cable limiting plate will not interfere with the cable limiting groove.

[0012] Preferably, the size of the insert plate is matched with the size of the slot, the inner diameter of the arc-shaped opening slot is larger than the inner diameter of the locking screw hole, and weight-reducing grooves are provided on both outer ends of the cable tray body to ensure the stability of the insert plate when it is inserted into the slot.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Equipped with a cable tray body, sliding groove, cable limiting components, and weight reduction groove, the cable limiting components can effectively fix cables of different sizes, preventing cables from moving freely within the cable tray, reducing wear and damage caused by cable shaking, and extending the service life of the cables. The semi-circular inner cable limiting plate and adjustable spring structure can adapt to cables of different outer diameters, providing a tighter fit and stable limiting, ensuring the safe placement of cables.

[0015] 2. Through modular design, the combination of insert plates, slots, and locking bolts makes the installation and disassembly of cable trays more convenient and faster, improving construction efficiency. Attached Figure Description

[0023] Please see Figure 1-Figure 5 This utility model provides a technical solution: a modular combined cable tray, including a cable tray body 1. Slide grooves 2 are provided on both sides of the inner side of the cable tray body 1. A cable limiting assembly 3 is provided inside the cable tray body 1. The cable limiting assembly 3 includes multiple inner cable limiting plates 309. Multiple linearly distributed springs 308 are connected to the upper end of each inner cable limiting plate 309. The springs 308 are connected to cable limiting grooves 307 opened at the inner end of outer cable limiting plates 306. Threaded moving plates 304 are connected to both sides of the outer cable limiting plates 306. The threaded moving plates 304 are slidably connected to the slide grooves 2. Rotating rods 303 are threadedly connected to the threaded moving plates 304 on the same side. Two symmetrical threaded grooves are opened on the outer periphery of the rotating rods 303. Each threaded moving plate 304 is slidably connected to the slide grooves 2. A contact plate 305 is rotatably connected to the upper end of each rotating rod 303. The contact plate 305 is connected to the cable tray body 1.

[0024] In this embodiment, the end of the rotating rod 303 away from the contact plate 305 is connected to a rotating shaft 302, the rotating shaft 302 is connected to a rotating handle 301, the upper end of the rotating handle 301 abuts against the cable tray body 1, and the rotating handle 301 is located on the outside of the cable tray body 1.

[0025] Specifically, rotating the handle 301 rotates the rotating rod 303, thereby displacing the threaded moving plate 304.

[0026] In this embodiment, a slot 5 is provided at the front end of the cable tray body 1, and two symmetrically arranged arc-shaped opening slots 6 are provided on both sides of the cable tray body 1. Each arc-shaped opening slot 6 is connected to the slot 5. An insert plate 8 is connected to the end of the cable tray body 1 away from the slot 5. Locking screw holes 9 are provided at the front ends of both sides of the insert plate 8. Locking bolts 7 are provided in the arc-shaped opening slots 6, and the locking bolts 7 are matched with the locking screw holes 9.

[0027] Specifically, insert the plate 8 of one cable tray body 1 into the slot 5 of another cable tray body 1. After aligning the locking screw holes 9 on both sides of the plate 8 with the arc-shaped opening slots 6 on both sides of the cable tray body 1, screw the locking bolt 7 into the locking screw holes 9 to achieve a firm connection between the cable trays.

[0028] In this embodiment, a guide post 310 is connected to the middle of the upper end of each inner cable limiting plate 309, and the guide post 310 is slidably connected to the outer cable limiting plate 306.

[0029] Specifically, the guide post 310 ensures the stability of the movement of the cable outer limit plate 306.

[0030] In this embodiment, the lower end of the cable outer limiting plate 306 is connected to a plurality of evenly distributed blocking plates 311, the length of which is equal to the length of the cable tray body 1.

[0031] Specifically, the blocking plate 311 can block the cables from both sides to prevent mutual interference between them.

[0032] In this embodiment, the lengths of the outer cable limiting plate 306 and the inner cable limiting plate 309 are matched with the dimensions of the cable tray body 1, and the width of the outer cable limiting plate 306 is smaller than the width of the cable tray body 1.

[0033] Specifically, this ensures that when the two cable tray bodies 1 are closed, the cable outer limiting plate 306 can also be closed, preventing the cable from becoming loose.

[0034] In this embodiment, the inner cable limiting plate 309 is semi-circular in shape, and the inner diameter of the cable limiting groove 307 is larger than the outer diameter of the inner cable limiting plate 309.

[0035] Specifically, this ensures that the inner limit plate 309 of the cable does not interfere with the cable limit groove 307.

[0036] In this embodiment, the size of the insert plate 8 is matched with the size of the slot 5, the inner diameter of the arc-shaped opening slot 6 is larger than the inner diameter of the locking screw hole 9, and weight reduction slots 4 are provided on both outer ends of the cable tray body 1.

[0037] Specifically, this ensures the stability of the plug-in board 8 when it is plugged into the slot 5, and reduces the weight of the cable tray.

[0038] This utility model enables the effective fixing of cables of different sizes through the cable limiting component 3, preventing the cables from moving freely in the cable tray, reducing wear and damage caused by cable shaking, and extending the service life of the cables. The semi-circular inner cable limiting plate 309 and the adjustable spring 308 structure can adapt to cables of different outer diameters, providing a tighter fit and stable limiting, ensuring the safe placement of the cables.

[0039] Working principle: First, when installing cables, place the cables inside the cable tray body 1. Rotating the handle 301 drives the rotating shaft 302 to rotate, which in turn rotates the rotating rod 303. Two symmetrical threaded grooves on the outer periphery of the rotating rod 303 drive the threaded moving plates 304 on both sides to move towards or away from each other within the sliding groove 2. The threaded moving plates 304 drive the outer cable limiting plate 306 to move. The outer cable limiting plate 306 is connected to the inner cable limiting plate 309 via a spring 308. When the threaded moving plates 304 move, the distance between the outer cable limiting plate 306 and the inner cable limiting plate 309 changes to accommodate cables of different diameters. The limiting plate 309 is semi-circular in shape, which can better fit the cable surface. The guide post 310 ensures the stability of the movement of the cable outer limiting plate 306. At the same time, the blocking plate 311 prevents the cable from coming out between the limiting plates. When multiple cable tray bodies 1 are assembled, the insert plate 8 of one cable tray body 1 is inserted into the slot 5 of another cable tray body 1. After the locking screw holes 9 on both sides of the insert plate 8 are aligned with the arc-shaped opening slots 6 on both sides of the cable tray body 1, the locking bolt 7 is screwed into the locking screw holes 9 to achieve a firm connection between the cable trays. The weight reduction groove 4 ensures the strength of the cable tray while ensuring the stability of the insert plate 8 when it is inserted into the slot 5, thus reducing the weight of the cable tray.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
