Technical Field

[0001] This utility model belongs to the field of cable tray technology, and in particular relates to an interconnection structure for multi-compartment cable trays in underground pipe corridors. Background Technology

[0002] Cable trays are typically installed inside underground utility tunnel compartments for cable laying. Cable trays between multiple underground utility tunnel compartments need to be interconnected. This requires the use of cable tray interconnection components to connect the cable trays. Cable tray interconnection components are accessories used to connect different parts of the cable tray, enabling functions such as cable branching, turning, and merging, thereby making cable laying more flexible and orderly, and improving the stability and maintainability of the cabling system.

[0003] When installing cable tray interchange components, internal partitions are required to separate different types of cables, preventing interference or entanglement. After installation, the partition positions need adjustment as needed, which is cumbersome. Therefore, a multi-compartment cable tray interchange structure for underground utility tunnels is needed. This structure allows for easy adjustment of the partition positions, eliminating the need for manual removal and ensuring quick adjustment of the partitions. Utility Model Content

[0004] The purpose of this utility model is to provide an interconnection structure for multi-compartment cable trays in underground utility tunnels, which allows for adjustment of the position of the partition plates through an adjustable structure, avoiding the need for users to dismantle and adjust the partition plates, and ensuring the speed of adjustment of the partition plates of the cable tray interconnection components, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-compartment cable tray interconnection structure for underground pipe gallery, comprising a shell, a cover plate provided on the top of the shell, an adjusting plate provided in the inner cavity of the shell, multiple pairs of limiting grooves opened on the surface of the adjusting plate, multiple pairs of longitudinal limiting strips fixedly connected to the inner cavity of the shell, a sleeve fixedly connected to the bottom of the inner cavity of the shell, a threaded rod rotatably connected to the inner cavity of the sleeve, a fixed sleeve provided through the top of the adjusting plate, a threaded sleeve fixedly connected to the inner cavity of the fixed sleeve, the threaded sleeve sliding in the inner cavity of the sleeve, the threaded rod passing through the threaded sleeve and threadedly connected to the threaded sleeve, the top of the threaded rod passing through to the outside of the sleeve and fixedly connected to a rotating head, multiple pairs of hooks fixedly connected to the surface of the cover plate, and multiple pairs of hooks fixedly connected to the surface of the shell, the hooks and hooks being adapted to each other.

[0006] Preferably, a limiting sleeve is fixedly connected to the bottom of the cover plate, and the limiting sleeve is adapted to the sleeve.

[0007] Preferably, the surface of the housing has multiple connection holes, which are elongated openings.

[0008] Preferably, the housing is cross-shaped, the cover plate is adapted to the housing, and the adjusting plate slides within the inner cavity of the housing.

[0009] Preferably, the corners of the limiting strip are arc surfaces, the threaded sleeve is adapted to the inner cavity of the sleeve, and the rotating head is a hexagonal nut.

[0010] The beneficial effects of this utility model are: 1. This utility model rotates the rotating head to make the threaded rod rotate, so that the threaded rod and the threaded sleeve move together. Through the limiting groove and the limiting strip, the threaded sleeve drives the adjusting plate to move up and down. This allows the position of the partition plate to be adjusted through the adjusting structure, avoiding the need for the user to remove the partition plate for adjustment and ensuring the speed of adjusting the partition plate of the cable tray interconnection component. 2. By setting a limiting sleeve, when the cover plate is fixed to the top of the shell by hooks and buckles, the limiting sleeve will be fitted on the top of the sleeve, preventing the sleeve from bending under pressure and ensuring the stability of the sleeve.

[0016] In summary, this multi-compartment cable tray interconnection structure in the underground utility tunnel allows for the rotation of the rotating head 10, which in turn causes the threaded rod 7 to rotate, resulting in the threaded movement of the threaded rod 7 and the threaded sleeve 9. Through the limiting groove 4 and the limiting strip 5, the threaded sleeve 9 drives the adjusting plate 3 to move up and down. This allows for the adjustment of the partition plate's position via the adjustment structure, avoiding the need for users to dismantle and adjust the partition plate, and ensuring the speed of partition plate adjustment in the cable tray interconnection component.
