Technical Field
[0001] This utility model relates to the technical field of cable trays, specifically to a clip-on cable tray with internal snap-fit design. Background Technology
[0002] Cable trays are devices used to support and protect cables for power, communication, and data transmission. They are typically made of metallic or non-metallic materials and are primarily used to carry and arrange various cables, allowing for orderly cabling. They also offer good mechanical protection and fire resistance. Cable trays can be installed on walls, ceilings, or floors and are widely used in construction, IT, manufacturing, and transportation. While cable trays have different definitions and uses in different industries, they all aim to provide support and protection for cables to ensure the effective operation and safety of cable systems.
[0003] In common cable trays, the trays are usually fixed together with bolts. Using bolts requires tightening the nuts one by one, which increases installation time, especially when a large number of connections are needed. If the bolts are not installed properly, the bolt heads or nuts may protrude, scratching the cable sheath and causing cable damage, which has a certain adverse effect on the use process. To address this, we propose a clip-on cable tray with internal snap-fit. Utility Model Content
[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides an internally snap-fit cable tray, offering advantages such as improved installation efficiency and enhanced flexibility. A positioning post at one end of the first cable tray is inserted into the inner side of a positioning insertion hole. The positioning block, through the action of a damper and elastic element at the rear end, provides elasticity and snaps into the inner side of the anti-detachment locking hole for positioning, enabling rapid splicing between the first and second cable trays. A limiting plate inside the movable connecting hole serves to limit movement and prevent slippage. An upper movable protective plate, positioned at the upper end of the connecting frame by the second and first magnetic blocks, acts as a barrier for the cables inside the first and second cable trays, preventing them from detaching. The snap-fit connection requires no tools, allowing for rapid connection between cable trays, significantly shortening installation time, improving work efficiency, and making disassembly and reinstallation of the cable trays more convenient. The position and layout of the cable trays can be flexibly adjusted as needed, effectively solving the problems in the background technology.
