[0002] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) supports and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance.

[0003] In existing cable tray installations, if indoor beams obstruct the installation, the length of the hangers connecting the installation foundation and the cable tray needs to be adjusted to avoid the beams for easier laying. This is typically done by cutting the hangers to the required length, but on-site cutting is inconvenient and requires additional cutting equipment. Furthermore, existing hangers lack the function of supporting the cable tray, requiring manual labor or supporting equipment to lift the tray during installation and secure it to the installation foundation using the hangers, resulting in low installation efficiency. Therefore, this invention proposes an adjustable cable tray device for easier laying, to solve the aforementioned problems. Utility Model Content

[0016] Please see Figure 1-7 This utility model provides a technical solution: an adjustable cable tray for easy installation, comprising a frame 1, a hanger assembly 2, and a cable fixing assembly 3. The frame 1 is fixed to the installation foundation via the hanger assembly 2. The frame 1 includes a base plate 101, side plates 102, a first assembly groove 103, a top plate 104, and a second assembly groove 105. The base plate 101 has first assembly grooves 103 on both sides for assembling the side plates 102, and a top plate 104 is provided above the base plate 101. The inner side of the upper end of the side plates 102 has a groove for assembling the top plate 104. The second assembly slot 105 is provided, and the side plate 102 is provided with a docking hole 5 that matches the positioning hole 202. The frame 1 is provided with a wire fixing assembly 3 inside. The wire fixing assembly 3 includes a base 301, a wire fixing groove 302 and a pressure plate 303. Multiple sets of bases 301 are detachably provided on the top of the base plate 101. Each set of bases 301 is provided with a wire fixing groove 302. A pressure plate 303 is detachably provided on the top of the base 301. One side of the pressure plate 303 is hinged to the base 301, and the other side of the pressure plate 303 is connected to the top of the base 301 by connecting bolts. At this point, the assembled frame 1 can be placed on the assembly plate 207, which supports the frame 1 without the need for manual or external support. The locking bolt 6 passes through the connecting hole 4 on the side plate 102, and one end passes through the positioning hole 202 on the extension plate 203 and the boom 201, then is locked with a nut, completing the installation of the frame 1. During cable laying, after the cable is placed in the multiple cable trays 302 on the base plate 101, the upper pressure plate 303 is adjusted via the hinge shaft, and one side of the pressure plate 303 is connected to the base 301 via the connecting bolt 6, thus securing the cable. The boom assembly 2 includes a boom 201, positioning holes 202, an extension plate 203, a fixing box 204, an adjusting plate 205, a moving shaft 206, an assembly plate 207, a moving groove 208, and a stop block 209. The boom 201 has a moving groove, within which the extension plate 203 slides. Both the boom 201 and the extension plate 203 have four sets of corresponding positioning holes 202. The lower outer wall of the extension plate 203 has a fixing box 204. Adjusting plates 205 are hinged to both sides of the fixing box 204, and an assembly plate 207 is hinged to the upper part of the inside of the fixing box 204. The assembly plate 207 is provided with a moving groove 208, and a moving shaft 206 is provided in the moving groove 208. The front end of the adjusting plate 205 is hinged to the moving shaft 206. A stop block 209 is hinged in the moving groove 208. One end of the stop block 209 is hinged to the inside of the assembly plate 207. A locking bolt 6 is provided in the docking hole 5. One end of the locking bolt 6 passes through the positioning hole 202 on the extension plate 203 and the boom 201 and is provided with a nut. A fixing plate 7 is provided at the upper end of the boom 201. An assembly bolt is provided on the fixing plate 7. The side plates 102 of adjacent frames 1 are connected by a connector 4. In use, first, install multiple sets of hanger assemblies 2 at designated positions on the indoor ceiling using the fixing plate 7, following the installation steps. Then, when encountering indoor beams obstructing the installation, pull the extension plate 203 out of the hanger arm 201 to a specified length and lock it in place using bolts through the positioning holes 202 on the hanger arm 201 and extension plate 203. Next, install multiple sets of bases 301 onto the base plate 101 using bolts, and then insert the lower end of the side plate 102 into the first assembly slot 103 on the base plate 101 to complete the assembly. Pull the adjusting plate 205, causing the adjusting plate 205 to move the moving shaft 206 within the moving slot 208, thus adjusting and unfolding the assembly plate 207 by 90 degrees. As the moving shaft 206 moves, it rotates the stop block 209, which then moves to one end of the moving slot 208. The stop block 209, in conjunction with the assembly plate 207, automatically resets to hold the moving shaft 206 in place, preventing it from moving during use. During transportation, the assembly plate 207 is inserted into the fixed box 204 to reduce the space occupied.

[0017] Working Principle: When using the adjustable cable tray for easy installation, first, install multiple sets of hanger assemblies 2 at designated positions on the indoor ceiling using the fixing plate 7, following the installation steps. Then, when encountering indoor beams obstructing the installation, pull the extension plate 203 out of the hanger arm 201 to the designated length and lock it in place using bolts through the positioning holes 202 on the hanger arm 201 and extension plate 203. Next, install multiple sets of bases 301 onto the base plate 101 using bolts, and then insert the lower end of the side plate 102 into the first assembly slot 103 on the base plate 101 to complete the assembly. Pull the adjusting plate 205, causing the adjusting plate 205 to move the moving shaft 206 within the moving slot 208, thus adjusting and unfolding the assembly plate 207 by 90 degrees. During the movement of the moving shaft 206, the stop block 209 rotates and moves to one end of the moving slot 208. The stop block 209, in conjunction with the assembly plate 207, automatically resets to hold the moving shaft 206 in place, preventing movement during use. During transportation, the assembly plate 207 is retracted into the fixing box 204 to reduce space occupation. At this time, the assembled frame 1 can be placed on the assembly plate 207, which supports the frame 1 without the need for manual or external equipment support. The locking bolt 6 passes through the connecting hole 4 on the side plate 102, and one end passes through the positioning hole 202 on the extension plate 203 and the boom 201, and is then locked with a nut, completing the installation of the frame 1. During cable laying, after the cable is placed in the multiple cable trays 302 on the base plate 101, the upper pressure plate 303 is adjusted via the hinge shaft, and one side of the pressure plate 303 is connected to the base 301 via the connecting bolt 6, thus fixing the cable. All the work not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0018] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
