[0002] To protect the optical cable during installation, it can be installed inside the cable tray. According to patent authorization announcement number CN203287573U, a grooved optical cable tray is proposed. This utility model relates to a grooved optical cable tray comprising N interconnected cable tray units. The connected cable tray units form a routing space for the optical cable.

[0023] Please see Figure 1-5 The cable tray 1 is internally fixedly connected with a guide rail 5, which slides in contact with the cover 2. During splicing, the guide rail 5 of one cable tray 1 can be processed to slide into the outside of the protrusion of another cable tray 1. The bottom inner side of the cable tray 1 is provided with a splicing groove 7, the shape of which is consistent with the splicing piece 6. During splicing, the splicing piece 6 can be slid into the splicing groove 7. One end of the spring 10 is fixedly connected to the fixing nail 8, and the other end of the spring 10 is fixedly connected to the limiting frame 9. The spring 10 can automatically reset the limiting frame 9 through its elastic force.

[0024] Please see Figure 1-5The optical cable limiting mechanism 4 includes a pressing frame 41. The upper end of the support frame 3 is hinged to the pressing frame 41. Anti-slip pads 42 are glued inside both the pressing frame 41 and the support frame 3. A fixing cover 43 is fixedly connected to the outside of the support frame 3. A connecting pin 44 is slidably connected inside the fixing cover 43. A locking frame 45 is fixedly connected to one end of the connecting pin 44. A second spring 46 is provided on the outside of the connecting pin 44. The locking frame 45 can limit the pressing frame 41. The locking frame 45 is in slidable contact with both the pressing frame 41 and the fixing cover 43. The pressing frame 41 is in contact with the fixing cover 43.

The other end of the second spring 46 is fixedly connected to the fixing cover 43. The second spring 46 can automatically reset the connecting pin 44 through its elastic force.

[0025] The specific implementation process of this utility model is as follows: When in use, after aligning the splicing piece 6 of one cable tray 1 with the splicing groove 7 of another cable tray 1, slide the guide rail 5 of the cable tray 1 into the interior of the other cable tray 1, so that the two cable trays 1 can be spliced. At the same time, pull the limiting frame 9, and the limiting frame 9 compresses the spring 10. Then slide the cover 2 to the outside of the cable tray 1. After the cover 2 slides to the outside of the cable tray 1, it can limit the other cable tray 1 through the guide rail 5. After the sliding is completed, release the limiting frame 9, and the spring 10 returns to its original position. The spring 10 can drive the limiting frame 9 to slide to the outside of the cover 2 through its elasticity, so that the assembly of the cable tray 1 can be completed.

[0026] Then, place the optical cable inside the support frame 3. After placement, flip the lower pressure frame 41 back to its original position. Then pull the locking frame 45. The locking frame 45 compresses the second spring 46 through the connecting pin 44. When the lower pressure frame 41 is released from the support frame 3, release the locking frame 45. The second spring 46 returns to its original position. The second spring 46 can automatically reset the locking frame 45 through its elasticity. The locking frame 45 slides to the outside of the lower pressure frame 41, thus completing the installation of the optical cable.
