Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, and in particular to a cable tray turning structure. Background Technology

[0002] Cable trays are widely used auxiliary equipment for cable laying in modern industrial and construction engineering, and are often used for centralized cable laying and support. However, when encountering corners, bends or space-constrained locations, existing cable trays often require cutting, welding or adapters for connection, which is complicated to install, has poor stability, and is inconvenient to disassemble and maintain, affecting construction efficiency and overall system safety.

[0003] Therefore, there is an urgent need for a steering structure that is simple in structure, easy to install, and capable of turning and flexibly splicing the cable tray, in order to adapt to diverse construction needs and improve installation quality and efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cable tray steering structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable tray turning structure includes a circular base, a circular plate, and an annular trapezoidal groove and an annular mounting groove formed by circular rings on the top of the circular plate. The diameter of the annular mounting groove is larger than the diameter of the trapezoidal groove. Several fixed units are slidably disposed in the trapezoidal groove. Several movable bases are slidably disposed in the annular mounting groove. A cable tray unit is fixed to the top of the fixed units and the movable bases. The cable tray unit and the movable base are fixed together by a second screw.

[0007] Preferably, the circular base further includes an annular step portion disposed on the outer periphery of the top of the circular plate.

[0008] Preferably, it also includes an annular cover plate used in conjunction with the annular step portion; when the annular cover plate is installed on the annular step portion, the annular mounting groove has a T-shaped structure; the annular cover plate is fixed to the circular base by a first screw.

[0009] Preferably, the fixing unit includes a first T-shaped base that matches the trapezoidal groove, and a fixing bolt disposed on the top of the first T-shaped base.

[0010] Preferably, the movable base includes a second T-shaped base that matches the annular mounting groove, and a fixing plate is fixed to the top of the second T-shaped base, with a plurality of first mounting holes provided on the fixing plate.

[0011] Preferably, the cable tray unit includes a cable tray body, which has fastening holes that match the fixing bolts, and a second mounting hole that matches the fixing plate. The side wall of the cable tray body has a connection hole for connecting with an adjacent cable tray.

[0012] Preferably, the fixing bolt passes through the fastening hole and is threaded to the fastening nut.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model utilizes a circular base structure combining a trapezoidal groove and an annular mounting groove, allowing the cable tray unit to slide and adjust its direction along the annular track during installation. This effectively solves the problem of installation difficulties for existing cable trays when encountering corners or complex paths. Compared to traditional methods that achieve turning through cutting and welding, this structure achieves multi-angle adjustment without damaging the cable tray itself, significantly improving construction efficiency and adaptability to the construction environment.

[0015] 2. This utility model adopts a separate sliding design for the fixed unit and the movable base, allowing the cable tray unit to flexibly switch between fixed and adjustable states. This not only improves the stability of the overall structure but also enhances installation flexibility. Especially during maintenance or wiring changes, cable tray components can be easily disassembled and replaced, avoiding the problems of high workload and high wear and tear caused by repeated disassembly and assembly in traditional structures, thus greatly reducing subsequent maintenance costs.

[0016] 3. This utility model further incorporates an annular cover plate, which forms a T-shaped limiting structure with the stepped portion on the circular base. After being secured with screws, it effectively covers and protects the sliding structure within the base, preventing the entry of external impurities such as dust and moisture, ensuring long-term stable use. Simultaneously, this structure enhances the mechanical strength of the cable tray's turning parts, solving the problems of low connection strength and easy deformation in traditional cable tray connectors, thus improving the safety and service life of the entire system.
