Description

Technical Field

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

[0002] Interlocking galvanized cable trays are cable laying support structures made of galvanized steel plates assembled by splicing. They flexibly assemble the various parts of the cable tray together with connectors, eliminating the need for welding, making them easy to install and maintain. They have good corrosion resistance and mechanical strength, and are suitable for cable laying and protection in various building and industrial environments.

[0003] Currently, a certain gap needs to be left when installing and splicing two galvanized cable trays to facilitate air circulation and improve the heat dissipation of the cables. At the same time, the gap provides the necessary space for cable inspection, maintenance, and replacement, making it convenient for operators to carry out inspection and maintenance work. However, currently, two galvanized cable trays are generally installed and spliced ​​by bolts and connecting plates. The connecting plates and galvanized cable trays have pre-set mounting holes. Although the splicing installation of two galvanized cable trays has good stability, the distance between the two galvanized cable trays is fixed because the pre-set mounting holes of the connecting plates and galvanized cable trays need to correspond. Since different cables have different heat dissipation requirements and maintenance space requirements, when the distance between the two galvanized cable trays cannot be adjusted, the galvanized cable trays cannot meet the needs of various different cables. Therefore, a splicing type of galvanized cable tray is proposed. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a splicing galvanized cable tray, comprising a first galvanized cable tray, a second galvanized cable tray, and two connecting mounting plates, wherein the outer walls of the first galvanized cable tray and the outer walls of the second galvanized cable tray are provided with mounting structures;

[0006] The installation structure includes mounting screws movably installed inside the connecting mounting plates. An adjusting frame is fixedly installed on the outer wall of the second galvanized cable tray. Threaded rods are fixedly installed on the top and bottom outer walls of the adjusting frame. Nuts are threaded onto the outer periphery of the threaded rods. Mounting seats are fixedly installed on the opposite outer walls of the two connecting mounting plates. Limiting plates are movably installed on the opposite outer walls of the two mounting seats. Fixing screws are movably installed inside the limiting plates. Two protective frame plates are movably installed between the two limiting plates. Card holders are fixedly installed on the opposite outer walls of the two limiting plates.

[0007] Furthermore, the connecting mounting plate has mounting holes inside, and the top and bottom of the first galvanized cable tray both have first threaded grooves. The mounting screws pass through the mounting holes and are threaded into the first threaded grooves, and are of the same size.

[0008] Furthermore, the inner walls of the front and rear sides of the adjusting frame are fixedly connected to the outer walls of the front and rear sides of the second galvanized cable tray, respectively. There are gaps between the inner walls of the top and bottom of the adjusting frame and the outer walls of the top and bottom of the second galvanized cable tray. The connecting mounting plate is slidably connected at the gap and is of a suitable size.

[0009] Furthermore, the mounting base has a second threaded groove inside, the limiting plate has a through hole inside, and the fixing screw passes through the through hole and is threaded inside the second threaded groove and is of the same size.

[0010] Furthermore, a U-shaped groove is provided on the left side of the limiting plate, and the threaded rod is slidably connected inside the U-shaped groove and is of a suitable size. The outer walls of the two nuts on opposite sides are respectively attached to the outer walls of the two limiting plates on opposite sides, and the adjusting frame is movably installed between the two limiting plates.

[0011] Furthermore, the protective frame plate is U-shaped, with the outer walls of the two protective frame plates on opposite sides fitting together. The outer walls of the two protective frame plates on opposite sides are provided with slots, and the slots are fitted into the slots and are of the same size. The front and back sides of the protective frame plate are provided with a number of heat dissipation vents, and the front and back sides of the first and second galvanized cable trays are provided with a number of heat dissipation holes.

[0012] Furthermore, both the first galvanized cable tray and the second galvanized cable tray are slidably connected between two connecting mounting plates, and the first galvanized cable tray and the second galvanized cable tray are the same size.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This modular galvanized cable tray uses mounting screws to position the first galvanized cable tray between two connecting mounting plates. An adjusting frame causes the second galvanized cable tray to slide and adjust its position between the mounting plates. A limiting plate, fixing screws, mounting base, threaded rod, and nut secure the adjusting frame through friction. This allows for easy adjustment of the distance between the first and second galvanized cable trays according to cable heat dissipation requirements and maintenance space needs, thus expanding the applicability of this modular galvanized cable tray.
