Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, and more specifically, to an expandable cable tray. Background Technology
[0002] With the rapid development of modern industry, data centers, intelligent buildings, and new energy, cable trays, as the core support structure of power and signal transmission systems, are facing increasingly complex and large-scale applications. Cable trays are primarily used for integrated cabling in power supply systems, including power transmission and wired telecommunications, serving as support components for cable laying. These support components are most widely used in power supply departments, centralized power distribution systems in industrial and mining enterprises, hotels, and comprehensive office facilities, as well as in wired telecommunications. Typically, cable trays are pre-installed before the cables are laid.
[0003] Traditional cable tray designs are mostly fixed structures. In the initial planning stage, the type of cable tray needs to be selected based on the estimated cable capacity, and future expansion needs are met by reserving redundant space or stacking cable tray layers. The drawback of this approach is that it cannot be freely adjusted for expansion according to actual needs. If the internal space of the initially installed cable tray is sufficient, the reserved redundant space may not be enough to meet the actual expansion needs. At the same time, by stacking cable tray layers, another cable tray needs to be installed, which occupies more space. If multiple cable trays need to be disassembled for maintenance later, it is inconvenient. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an expandable cable tray.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an expandable cable tray, including a base plate, side plates provided on both sides of the base plate, telescopic plates horizontally inserted into the base plate fixedly provided on the bottom inner sidewalls of the two side plates, locking mechanisms provided at the four corners of the top of the base plate, and an adjustable cover assembly provided between the tops of the two side plates.
[0006] As a further improvement to the technical solution of this utility model, the inside of the base plate is provided with a telescopic cavity in the horizontal direction corresponding to the outside of the telescopic plate, and the vertical cross-sectional width of the telescopic cavity is greater than the thickness of the telescopic plate.
[0007] As a further improvement to the technical solution of this utility model, the locking mechanism includes a groove provided at the top of the base plate near the corner, the bottom of the groove is connected to an internal hexagon bolt for locking the position of the telescopic plate, and the bottom of the groove is provided with a threaded hole matching the external thread structure of the internal hexagon bolt, the threaded hole communicating with the telescopic cavity and the groove.
[0008] As a further improvement to the technical solution of this utility model, the adjustable cover assembly includes a middle plate disposed above the base plate, and two L-shaped plates are symmetrically connected to the bottom of the middle plate, with the vertical edges of the two L-shaped plates respectively attached to the top outer wall of the two side plates.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] As attached Figure 1-6 An expandable cable tray is shown, including a base plate 1, side plates 2 are provided on both sides of the base plate 1, and telescopic plates 3 are fixedly provided on the bottom inner side walls of the two side plates 2, which are horizontally inserted into the base plate 1. Locking mechanisms are provided at the four corners of the top of the base plate 1, and an adjustable cover assembly is provided between the tops of the two side plates 2.
[0024] As attached Figure 1-2 and attached Figure 5-6 As shown, a telescopic cavity 4 is provided inside the base plate 1 along the horizontal direction corresponding to the outside of the telescopic plate 3. The vertical cross-sectional width of the telescopic cavity 4 is greater than the thickness of the telescopic plate 3, which facilitates the stable horizontal movement of the telescopic plate 3 within the telescopic cavity 4 inside the base plate 1.
[0025] As attached Figure 1-2 and attached Figure 5-6 As shown, the locking mechanism includes a groove 5 located at the top of the base plate 1 near the corner. The bottom of the groove 5 is connected to an internal hex bolt 6 for locking the position of the telescopic plate 3. The bottom of the groove 5 is provided with a threaded hole 7 that matches the external thread structure of the internal hex bolt 6. The threaded hole 7 communicates with the telescopic cavity 4 and the groove 5, which facilitates locking the adjusted telescopic plate 3 during use, thereby allowing the internal space of the entire cable tray to be adjusted and expanded according to actual needs.
[0026] As attached Figure 1 and attached Figure 3-4 As shown, the adjustable cover assembly includes a middle plate 10 disposed above the base plate 1. Two L-shaped plates 9 are symmetrically connected to the bottom of the middle plate 10. The vertical edges of the two L-shaped plates 9 are respectively attached to the top outer walls of the two side plates 2. A T-shaped locking block 11 is disposed on the top of the L-shaped plate 9 in the horizontal direction. A T-shaped locking groove 12 is disposed on the bottom of the middle plate 10 corresponding to the outside of the T-shaped locking block 11 in the horizontal direction. Magnet blocks 8 are disposed at the bottom edges of both ends of the middle plate 10 for adsorbing and fixing to the upper surface of the L-shaped plate 9. A T-shaped slider 13 is disposed on the inner side wall of the vertical edge of the L-shaped plate 9. A misalignment groove 201 is disposed on the top outer wall of the side plate 2 to match the structure of the vertical edge of the L-shaped plate 9. A T-shaped sliding groove 202 is disposed on the inner side wall of the misalignment groove 201 to match the structure of the T-shaped slider 13. The adjustable cover assembly can be adaptively adjusted according to the adjustment of the bottom during use, so as not to cause the problem of the top cover not fitting when the space of the cable tray is expanded.
[0027] Working principle: This utility model designs an expandable cable tray, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, the cable tray designed in this technical solution can be quickly assembled. The assembled vertical cross-sectional structure is as follows: Figure 1 As shown, the bottom uses a telescopic plate 3 for telescopic adjustment, which, together with the side plates 2 on both sides, expands the internal space of the cable tray. A locking mechanism allows the telescopic plate 3 to be unlocked by loosening the hex bolts 6 as needed. The operator pulls the side plates 2 outwards, causing the telescopic plate 3 to move outwards. When the desired expansion space is reached, the hex bolts 6 are tightened. The adjustable cover assembly at the top can be adjusted adaptively according to the bottom adjustment, preventing mismatches when the cable tray expands its space. During operation, the L-shaped plate 9 slides at the bottom of the middle plate 10, and the magnetic block 8 helps maintain stability without external force. The T-shaped slider 13 at the end of the L-shaped plate 9, in conjunction with the T-shaped groove 202, limits vertical movement, preventing the adjustable cover assembly from falling off.
