[0002] Suspended cable trays are metal or composite material structural systems used to support and lay cables. They are typically installed on the top of buildings or at high altitudes via hangers, supports, or suspension devices, without occupying ground space. They have good load-bearing capacity and ventilation and heat dissipation performance, and are suitable for industrial plants, commercial buildings, data centers, and other places, facilitating cable installation, maintenance, and expansion.

[0003] For cable trays with 90-degree bends, existing suspended cable trays are usually fixed with connecting plates and bolts. This traditional connection method requires bolts to be installed from the top or side of the cable tray. In cases where the operating space is limited, the operating space is insufficient, which makes the installation and disassembly process very inconvenient and significantly increases the construction difficulty and operation time. Therefore, a suspended cable tray is proposed to address the above problems. Utility Model Content

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.

[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0017] Please see Figures 1-6 This utility model provides a technical solution: A suspended cable tray includes a first cable tray 1 and a second cable tray 3. The first cable tray 1 has an assembly hole 2 on its inner side, and a snap-fit ​​component 5 is snapped into the assembly hole 2. One side of the snap-fit ​​component 5 is fixedly connected to a connecting shell component 4. The connecting shell component 4 includes a bent shell 41, and a receiving hole 42 is opened on the inner side of the bent shell 41. A guide block 43 is fixedly connected to the inner side of the receiving hole 42. The snap-fit ​​component 5 includes a fixing seat 51. An arc-shaped spring 52 is fixedly connected to the end of the fixing seat 51 away from the bent shell 41. An assembly block 53 is fixedly connected to one side of the arc-shaped spring 52. Guide grooves 54 are opened at the upper and lower ends of the assembly block 53. A ramp 55 is opened at the end of the assembly block 53 away from the arc-shaped spring 52. The fixing seat 51 is fixedly connected to the bent shell 41.

[0018] As a further implementation of this solution, assembly holes 2 are opened inside the first cable tray 1 and the second cable tray 3. The first cable tray 1 and the second cable tray 3 are arranged at a 90-degree angle. The bent shell 41 is fitted on the outside of the first cable tray 1 and the second cable tray 3. The number of receiving holes 42 is the same as the number of assembly holes 2. The receiving holes 42 are aligned with the assembly holes 2. Through the above settings, the precise docking of the cable trays at the corner is achieved, ensuring accurate connection angle and improving the overall installation accuracy and structural stability. As a further implementation of this solution, guide blocks 43 are fixed at both the upper and lower ends of the receiving hole 42. The outer side of the guide block 43 slides on the inner side of the guide groove 54. Through the above arrangement, the movement trajectory of the connecting parts is effectively restricted, the guidance and stability during the assembly process are improved, and deviation or jamming is avoided. As a further implementation of this solution, the assembly block 53 extends into the interior of the assembly hole 2, and the outer side of the assembly block 53 fits against the inner side of the assembly hole 2. The number of assembly blocks 53 is the same as the number of assembly holes 2. Through the above settings, multi-point synchronous snap-fit ​​is achieved, enhancing the connection firmness and preventing the cable tray from loosening or falling off under stress or vibration. As a further implementation of this solution, guide grooves 54 are provided at both the upper and lower ends of the assembly block 53, and ramp 55 is located at the upper part of the assembly block 53. Through the above settings, the snap-fit ​​path and trigger position are optimized, making the connection action smoother, improving assembly efficiency and reducing the difficulty of operation. As a further implementation of this solution, a gap is provided between the arc-shaped spring 52 and the bent shell 41. The arc-shaped spring 52 is provided with an arc near the assembly block 53. The arc part of the arc-shaped spring 52 extends towards the assembly block 53. Through the above settings, the arc design provides elastic restoring force, ensuring that it automatically resets and emits a prompt sound after the snap-fit ​​is completed, thereby enhancing the operational feedback and connection reliability.

[0019] Workflow: When installing a 90-degree cable tray in a limited space, the first cable tray 1 and the second cable tray 3 are pre-installed on the hanger. The bent shell 41 is then fitted onto the outside of the first cable tray 1 and the second cable tray 3 from bottom to top, ensuring that the receiving hole 42 is aligned with the assembly hole 2 of the second cable tray 3 and the assembly hole 2 of the first cable tray 1. As the bent shell 41 is pushed upward, the ramp 55 of the assembly block 53 will contact the first cable tray 1 or the second cable tray 3. When the ramp 55 contacts the first cable tray 1 or the second cable tray 3, the compression of the first cable tray 1 and the second cable tray 3 pushes the assembly block 53 to move. The assembly block 53 slides inside the receiving hole 42, and the guide block 43 is located inside the guide groove 54. The guide block 43 and the guide groove 54 are designed to guide the movement of the assembly block 53. When the assembly block 53 moves, it acts as a limit stop. After the assembly block 53 moves, it will squeeze the arc-shaped spring 52. The arc-shaped spring 52 is set with a certain arc structure near the assembly block 53, which does not hinder the normal movement of the assembly block 53. When the assembly block 53 is aligned with the assembly hole 2, the assembly block 53 slides into the interior of the assembly hole 2 under the action of the restoring deformation force of the arc-shaped spring 52. This prevents the first cable tray 1 and the second cable tray 3 from separating from the connecting shell assembly 4. At the same time, a "click" sound will be heard, indicating that the first cable tray 1, the second cable tray 3 and the connecting shell assembly 4 are installed. Based on the above principle, the device realizes the connection between the first cable tray 1, the second cable tray 3 and the connecting shell assembly 4 by operating up and down. This is applicable to limited installation, improves the convenience of operation and reduces the installation intensity.

[0020] 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.
