[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a quick-installation cable tray structure for municipal underground integrated pipe gallery, including: a fixed recess 1 and an installation structure 2; A lifting protrusion 101 is fixedly connected to one end of the top of the fixed recess 1. A reinforcing corner block 1011 is fixedly connected between the lifting protrusion 101 and the fixed recess 1. An expansion bolt 102 is installed on the lifting protrusion 101. The fixed recess 1 is provided with a mounting structure 2, which includes the following components: Fixed convex plate 201: Fixedly connected to both sides of fixed concave frame 1. There are two sets of fixed convex plates 201. A screw rod 2011 is provided between the fixed convex plates 201. One end of the screw rod 2011 is fixedly connected to a rotating handle 2012. Movable belt plate 202: Located between fixed protrusions 201, the movable belt plate 202 has a threaded hole 2021. One end of the movable belt plate 202 passes through the through groove 2022 and is fixedly connected to the inner connecting support plate 2023. A guide protrusion 2024 is fixedly connected to the side of the connecting support plate 2023 near the fixed recess 1. The guide protrusion 2024 is slidably installed in the limiting slide groove 2025 on the inner side wall of the fixed recess 1. A locking block 2026 is fixedly connected to the bottom of the connecting support plate 2023. Cable tray 203: Located on the top of the fixed recess 1, cable tray 203 has connecting frames 2031 fixedly connected to both sides, and locking slots 2032 are provided in the connecting frames 2031. At the same time, locking blocks 2026 are inserted into the locking slots 2032.

[0022] The bottom of the cable tray 203 is fixedly connected with a positioning protrusion 204, and the bottom end of the fixed recess 1 is provided with a positioning groove 2041, and the positioning protrusion 204 is fitted into the positioning groove 2041.

[0023] By hoisting the cable tray 203 onto the fixed recess 1, and then having its bottom positioning protrusion 204 engage in the positioning groove 2041, the handle 2012 is turned to drive the lead screw 2011 to rotate. The lead screw 2011 engages with the threaded hole 2021 on the movable belt plate 202. The movable belt plate 202 is guided and limited in the limiting groove 2025 by the guide protrusion 2024 on the connecting support plate 2023, so that the lead screw 2011 drives the movable belt plate 202 to move. As a result, the movable belt plate 202 drives the locking block 2026 at the bottom of the connecting support plate 2023 to move, thereby engaging in the locking slot 2032, thus completing the installation of the cable tray 203.

[0024] Example 2: Based on Example 1, wherein, as Figure 5 and Figure 6 As shown, anti-rotation components 3 are provided on both sides of the fixed recess 1. The anti-rotation components 3 include a connecting plate 301, a connecting bottom cylinder 3011, and a movable sliding hole 3012. The connecting plate 301 is fixedly connected to the bottom of both sides of the fixed recess 1. The connecting bottom cylinder 301 is fixedly connected to the bottom of the connecting plate 301. A movable sliding hole 3012 is provided in the middle of the connecting bottom cylinder 3011.

[0025] A connecting slide rod 302 is slidably installed in the movable sliding hole 3012. One end of the connecting slide rod 302 is fixedly connected to an anti-rotation block 3021, and an anti-rotation groove 3022 is opened at the bottom of the rotating handle 2012. The anti-rotation block 3021 is fitted and snapped into the anti-rotation groove 3022.

[0026] A compression ring 3023 is fixedly connected to the outer side of the connecting slide rod 302. Limiting blocks 3024 are fixedly connected to both sides of the compression ring 3023. A compression groove 3025 is opened inside the connecting bottom cylinder 3011, and a spring 3026 is provided inside the compression groove 3025. At the same time, a pull handle 3027 is fixedly connected to the other end of the connecting slide rod 302.

[0027] A connecting inner ring 303 is fixedly connected in the extrusion groove 3025. Through grooves 3031 are opened on both sides of the connecting inner ring 303, and limit slots 3032 are opened on the other two sides of the connecting inner ring 303. The limit block 3024 is fitted and installed in the limit slot 3032.

[0028] When the locking block 2026 is inserted into the locking slot 2032, the anti-rotation groove 3022 at the bottom of the handle 2012 aligns with the anti-rotation block 3021. Pulling the handle 3027 moves the connecting slide rod 302, causing the anti-rotation block 3021 to disengage from the anti-rotation groove 3022. Then, the connecting slide rod 302 causes the compression ring 3023 to pass through the through groove 3031. Rotating the handle 3027 rotates the connecting slide rod 302, causing it to rotate. The connecting slide rod 302 then rotates the compression ring 3023, aligning the limiting block 3024 with the limiting groove 3032. Releasing the handle 3027 allows the connecting slide rod to move. The lever 302 will not reset due to the spring 3026, so the handle 2012 can be rotated. When the handle 2012 is limited, the connecting slide rod 302 is moved by pulling the handle 3027. Then, the handle 3027 is rotated to rotate the limiting block 3024 to align with the through groove 3031. At this time, the handle 3027 is released, and the compression ring 3023 is pushed to move under the elastic action of the spring 3026. The compression ring 3023 then moves the connecting slide rod 302, and the connecting slide rod 302 then drives the anti-rotation block 3021 to reset and be locked into the anti-rotation groove 3022 aligned with it, thereby completing the limitation of the handle 2012.

[0029] The specific usage and function of this embodiment are as follows: In this utility model, the cable tray 203 is hoisted onto the fixed recess 1, and then its bottom positioning protrusion 204 is engaged in the positioning groove 2041. The handle 2012 is then turned to rotate the lead screw 2011, which engages with the threaded hole 2021 on the movable belt plate 202. The movable belt plate 202 is guided and limited within the limiting groove 2025 by the guide protrusion 2024 on the connecting support plate 2023, causing the lead screw 2011 to move the movable belt plate 202. This, in turn, moves the locking block 2026 at the bottom of the connecting support plate 2023, securing it into the locking slot 2032, thus completing the installation of the cable tray 203. This method abandons the traditional complex bolt and welding connection method, using a snap-fit ​​structure to achieve rapid connection between the cable tray and the pipe rack. Simple and quick, it can significantly shorten the connection time, effectively improve the installation efficiency, and make the construction process more efficient and orderly. At this time, the anti-rotation groove 3022 at the bottom of the handle 2012 is aligned with the anti-rotation block 3021. Then, by pulling the handle 3027, the connecting slide rod 302 is moved. Then, the handle 3027 is rotated to rotate the limiting block 3024 to align with the through groove 3031. At this time, the handle 3027 is released, and under the elastic action of the spring 3026, the compression protrusion ring 3023 is pushed to move. The compression protrusion ring 3023 then drives the connecting slide rod 302 to move. The connecting slide rod 302 then drives the anti-rotation block 3021 to reset and be locked into the anti-rotation groove 3022 aligned with it, thereby completing the limiting of the handle 2012 and preventing the screw rod 2011 from rotating unexpectedly due to vibration of the pipe gallery environment, thus blocking the potential for loosening at the connection from the root.
