Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray with adjustable width. Background Technology

[0002] In modern buildings and industrial facilities, cable trays are essential structures for supporting and managing cables. Cable trays not only provide support for cables but also ensure their safe and stable arrangement, and facilitate cable maintenance and management. With the continuous development of power and communication systems, the design requirements for cable trays are becoming increasingly stringent, demanding greater functionality and flexibility.

[0003] Traditional cable trays typically have a fixed width and structure. While this design can meet the needs of cable arrangement in most cases, it has certain limitations in the following aspects:

[0004] Fixed width: Fixed-width cable trays lack sufficient flexibility when dealing with variations in the number or size of cables. Users need to use cable trays of different widths or make modifications, increasing the complexity of construction and maintenance.

[0005] Installation and maintenance difficulties: During the installation of fixed cable trays, additional processing of the wall or other supporting structures may be required to accommodate the size of the cable trays. This not only increases the installation cost but may also affect the efficiency of the installation.

[0006] Poor adaptability: When faced with changes in the type and quantity of cables, traditional cable trays often require replacing the entire cable tray system, which is not only time-consuming but also costly.

[0007] Therefore, it is essential to invent a cable tray with adjustable width. Utility Model Content

[0008] To address the aforementioned technical problems, this utility model provides an adjustable-width cable tray, solving the issues of existing cable trays still being unable to change width as needed, having poor support strength, and being unstable during use.

[0038] Cable support and protection: The adjusted cable tray structure places the cables on the support cable tray 3. The structural design of the support cable tray ensures that the cables remain stable during the laying process, preventing the cables from slipping or being damaged due to gravity or external forces. At the same time, the width of the support cable tray can be adjusted according to the number and size of the cables, providing flexible cable laying space.

[0039] Easy installation and maintenance: With its well-designed load-bearing and adjustment brackets, the cable tray installation is more flexible. Users can adjust the width and angle of the cable tray according to their actual needs. At the same time, the natural drop design of the adjustment unit plate makes the cable tray easier to maintain and adjust when there is no load.
